phoenix_title wx.propgrid.PGProperty

wx.propgrid.PGProperty is base class for all wx.propgrid.PropertyGrid properties and as such it is not intended to be instantiated directly.

In sections below we cover few related topics.

phoenix_title PropertyCategory

Not an actual property per se, but a header for a group of properties. Regardless inherits from wx.propgrid.PGProperty, and supports displaying ‘labels’ for columns other than the first one. Easiest way to set category’s label for second column is to call wx.propgrid.PGProperty.SetValue with string argument.

phoenix_title StringProperty

Simple string property. Supported special attributes:

  • PG_STRING_PASSWORD: Set to True in order to echo value as asterisks and to use TE_PASSWORD on the editor ( wx.TextCtrl).

  • PG_ATTR_AUTOCOMPLETE: Set to True to enable auto-completion (use a list of strings value), and is also supported by any property that happens to use a TextCtrl-based editor.

    PropertyGrid Property Attribute Identifiers

    Note

    wx.propgrid.StringProperty has a special trait: if it has value of “<composed>”, and also has child properties, then its displayed value becomes composition of child property values, similar as with wx.propgrid.FontProperty, for instance.

phoenix_title IntProperty

It derives from wx.propgrid.NumericProperty and displays value as a signed long integer. wx.propgrid.IntProperty seamlessly supports 64-bit integers (i.e. LongLong ) on overlfow. To safely convert variant to integer, use code like this:

# Thanks to the magic of Python nothing extra needs to be done here.

Getting 64-bit value:

def OnButtonClick(self, propGrid, value):
    dlgSize = wx.Size(... size of your dialog ...)
    dlgPos = propGrid.GetGoodEditorDialogPosition(self, dlgSize)

    # Create dialog dlg at dlgPos. Use value as initial string
    # value.
    with MyCustomDialog(None, title, pos=dlgPos, size=dlgSize) as dlg:
        if dlg.ShowModal() == wx.ID_OK:
            value = dlg.GetStringValue()
            return (True, value)
        return (False, value)

Setting 64-bit value:

self.SetFlag(wx.propgrid.PG_PROP_NO_ESCAPE)

Supported special attributes:

  • PG_ATTR_MIN, PG_ATTR_MAX to specify acceptable value range.

  • PG_ATTR_SPINCTRL_STEP, PG_ATTR_SPINCTRL_WRAP, PG_ATTR_SPINCTRL_MOTION: Sets SpinCtrl editor parameters.

phoenix_title UIntProperty

Like wx.propgrid.IntProperty, but displays value as int. To set the prefix used globally, manipulate PG_UINT_PREFIX string attribute. To set the globally used base, manipulate PG_UINT_BASE int attribute. Regardless of current prefix, understands (hex) values starting with both “0x” and “$” (apart from edit mode). Like wx.propgrid.IntProperty, wx.propgrid.UIntProperty seamlessly supports 64-bit integers (i.e. ULongLong ). Same Variant safety rules apply. Supported special attributes:

  • PG_ATTR_MIN, PG_ATTR_MAX: Specifies acceptable value range.

  • PG_UINT_BASE: Defines base. Valid constants are PG_BASE_OCT, PG_BASE_DEC, PG_BASE_HEX and PG_BASE_HEXL (lowercase characters). Arbitrary bases are not supported.

  • PG_UINT_PREFIX: Defines displayed prefix. Possible values are PG_PREFIX_NONE, wx.propgrid.PG_PREFIX_0x and PG_PREFIX_DOLLAR_SIGN. Only PG_PREFIX_NONE works with decimal and octal numbers.

  • PG_ATTR_SPINCTRL_STEP, PG_ATTR_SPINCTRL_WRAP, PG_ATTR_SPINCTRL_MOTION: Sets SpinCtrl editor parameters.

    PropertyGrid Property Attribute Identifiers

    Note

    For example how to use seamless 64-bit integer support, see wx.propgrid.IntProperty documentation (just use ULongLong instead of LongLong ).

phoenix_title FloatProperty

Like wx.propgrid.StringProperty, but converts text to a double-precision floating point. Default float-to-text precision is 6 decimals, but this can be changed by modifying PG_FLOAT_PRECISION attribute. Note that when displaying the value, sign is omitted if the resulting textual representation is effectively zero (for example, -0.0001 with precision of 3 will become 0.0 instead of -0.0). This behaviour is unlike what C standard library does, but should result in better end-user experience in almost all cases. Supported special attributes:

  • PG_ATTR_MIN, PG_ATTR_MAX: Specifies acceptable value range.

  • PG_FLOAT_PRECISION: Sets the (max) precision used when floating point value is rendered as text. The default -1 means shortest floating-point 6-digit representation.

  • PG_ATTR_SPINCTRL_STEP, PG_ATTR_SPINCTRL_WRAP, PG_ATTR_SPINCTRL_MOTION: Sets SpinCtrl editor parameters.

phoenix_title BoolProperty

Represents a boolean value. wx.Choice is used as editor control, by the default. PG_BOOL_USE_CHECKBOX attribute can be set to True in order to use check box instead. Supported special attributes:

  • PG_BOOL_USE_CHECKBOX: If set to True uses check box editor instead of combo box.

  • PG_BOOL_USE_DOUBLE_CLICK_CYCLING: If set to True cycles combo box instead showing the list.

phoenix_title LongStringProperty

Like wx.propgrid.StringProperty, but has a button that triggers a small text editor dialog. Note that in long string values, some control characters are escaped: tab is represented by “\t”, line break by “\n”, carriage return by “\r” and backslash character by “\”. If another character is preceded by backslash, the backslash is skipped. Note also that depending on the system (port), some sequences of special characters, like e.g. “\r\n”, can be interpreted and presented in a different way in the editor and therefore such sequences may not be the same before and after the edition. To display custom dialog on button press, you can subclass wx.propgrid.LongStringProperty and implement OnButtonClick, like this:

Also, if you wish not to have line breaks and tabs translated to escape sequences, then do following in constructor of your subclass:

Supported special attributes:

  • PG_DIALOG_TITLE: Sets a specific title for the text editor dialog.

phoenix_title DirProperty

Like wx.propgrid.LongStringProperty, but the button triggers dir selector instead. Supported special attributes:

  • PG_DIALOG_TITLE: Sets specific title for the dir selector.

    PropertyGrid Property Attribute Identifiers

phoenix_title FileProperty

Like wx.propgrid.LongStringProperty, but the button triggers file selector instead. Default wildcard is “All files…” but this can be changed by setting PG_FILE_WILDCARD attribute. Supported special attributes:

  • PG_DIALOG_TITLE: Sets a specific title for the file dialog.

  • PG_FILE_DIALOG_STYLE: Sets a specific wx.FileDialog style for the file dialog.

  • PG_FILE_WILDCARD: Sets wildcard (see wx.FileDialog for format details), “All

files…” is default. - PG_FILE_SHOW_FULL_PATH: Default True. When False, only the file name is shown (i.e. drive and directory are hidden). - PG_FILE_SHOW_RELATIVE_PATH: If set, then the filename is shown relative to the given path string. - PG_FILE_INITIAL_PATH: Sets the initial path of where to look for files.

phoenix_title EnumProperty

Represents a single selection from a list of choices - wx.adv.OwnerDrawnComboBox is used to edit the value.

phoenix_title FlagsProperty

Represents a bit set that fits in a long integer. wx.propgrid.BoolProperty sub- properties are created for editing individual bits. Textctrl is created to manually edit the flags as a text; a continuous sequence of spaces, commas and semicolons are considered as a flag id separator. Note: When changing “choices” (i.e. flag labels) of wx.propgrid.FlagsProperty, you will need to use wx.propgrid.PGProperty.SetChoices - otherwise they will not get updated properly. wx.propgrid.FlagsProperty supports the same attributes as wx.propgrid.BoolProperty.

phoenix_title ArrayStringProperty

Property that manages a list of strings. Allows editing of a list of strings in wx.TextCtrl and in a separate dialog. Supported special attributes:

  • PG_ARRAY_DELIMITER: Sets string delimiter character.

  • PG_DIALOG_TITLE: Sets a specific title for the editor dialog. Default is comma (‘,’).

    PropertyGrid Property Attribute Identifiers

phoenix_title DateProperty

Property representing wx.DateTime. Default editor is DatePickerCtrl, although TextCtrl should work as well. Supported special attributes:

  • PG_DATE_FORMAT: Determines displayed date format (with wx.DateTime.Format ). Default is recommended as it is locale-dependent.

  • PG_DATE_PICKER_STYLE: Determines window style used with wx.adv.DatePickerCtrl. Default is DP_DEFAULT | DP_SHOWCENTURY. Using DP_ALLOWNONE enables additional support for unspecified property value.

    PropertyGrid Property Attribute Identifiers

phoenix_title EditEnumProperty

Represents a string that can be freely edited or selected from list of choices - custom combobox control is used to edit the value.

phoenix_title MultiChoiceProperty

Allows editing a multiple selection from a list of strings. This is property is pretty much built around concept of wx.MultiChoiceDialog. It uses list of strings value. Supported special attributes:

  • PG_ATTR_MULTICHOICE_USERSTRINGMODE: If > 0, allows user to manually enter strings that are not in the list of choices. If this value is 1, user strings are preferably placed in front of valid choices. If value is 2, then those strings will placed behind valid choices.

  • PG_DIALOG_TITLE: Sets a specific title for the editor dialog.

    PropertyGrid Property Attribute Identifiers

phoenix_title ImageFileProperty

Property representing image file(name). Like wx.propgrid.FileProperty, but has thumbnail of the image in front of the filename and autogenerates wildcard from available image handlers. Supported special attributes:

  • PG_DIALOG_TITLE: Sets a specific title for the file dialog.

  • PG_FILE_DIALOG_STYLE: Sets a specific wx.FileDialog style for the file dialog.

  • PG_FILE_WILDCARD: Sets wildcard (see wx.FileDialog for format details), “All

files…” is default. - PG_FILE_SHOW_FULL_PATH: Default True. When False, only the file name is shown (i.e. drive and directory are hidden). - PG_FILE_SHOW_RELATIVE_PATH: If set, then the filename is shown relative to the given path string. - PG_FILE_INITIAL_PATH: Sets the initial path of where to look for files.

phoenix_title ColourProperty

Useful alternate editor: Choice. Represents wx.Colour. wx.Button is used to trigger a colour picker dialog. There are various sub-classing opportunities with this class. See below in wx.propgrid.SystemColourProperty section for details. Supported special attributes:

  • PG_COLOUR_HAS_ALPHA: If set to True allows user to edit the alpha colour component.

    PropertyGrid Property Attribute Identifiers

phoenix_title FontProperty

Represents wx.Font. Various sub-properties are used to edit individual subvalues. Supported special attributes:

  • PG_DIALOG_TITLE: Sets a specific title for the font dialog.

phoenix_title SystemColourProperty

Represents wx.Colour and a system colour index. wx.Choice is used to edit the value. Drop-down list has color images. Note that value type is wx.propgrid.ColourPropertyValue instead of wx.Colour (which wx.propgrid.ColourProperty uses).

class MyProperty(wx.propgrid.PGProperty):
    # All arguments of this ctor should have a default value -
    # use wx.propgrid.PG_LABEL for label and name
    def __init__(self,
                 label = wx.propgrid.PG_LABEL,
                 name = wx.propgrid.PG_LABEL,
                 value = ""):
        wx.propgrid.PGProperty.__init__(label, name)
        self.value = value

    def DoGetEditorClass(self):
        # Determines editor used by property.
        # You can replace 'TextCtrl' below with any of these
        # builtin-in property editor identifiers: Choice, ComboBox,
        # TextCtrlAndButton, ChoiceAndButton, CheckBox, SpinCtrl,
        # DatePickerCtrl.
        return wx.PGEditor_TextCtrl

    def ValueToString(self, value, argFlags):
        # TODO: Convert given property value to a string and return it
        return ""

    def StringToValue(self, text, argFlags):
        # TODO: Adapt string to property value and return it
        value = do_something(text)
        return (True, value)

In wx.propgrid.SystemColourProperty, and its derived class wx.propgrid.ColourProperty, there are various sub-classing features. To set a basic list of colour names, call wx.propgrid.PGProperty.SetChoices .

|phoenix_title| CursorProperty

Represents a wx.Cursor. wx.Choice is used to edit the value. Drop-down list has cursor images under some (wxMSW) platforms.

phoenix_title Creating Custom Properties

New properties can be created by subclassing wx.propgrid.PGProperty or one of the provided property classes, and (re)implementing necessary member functions. Below, each virtual member function has ample documentation about its purpose and any odd details which to keep in mind. Here is a very simple ‘template’ code:

import wx.propgrid as wxpg

class MyProperty(wxpg.PGProperty):

    def __init__(self, label=wxpg.PG_LABEL, name=wxpg.PG_LABEL, value=0):
        wxpg.PGProperty.__init__(self, label, name)
        self.my_value = int(value)

    def DoGetEditorClass(self):
        """
        Determines what editor should be used for this property type. This
        is one way to specify one of the stock editors.
        """
        return wxpg.PropertyGridInterface.GetEditorByName("TextCtrl")

    def ValueToString(self, value, flags):
        """
        Convert the given property value to a string.
        """
        return str(value)

    def StringToValue(self, st, flags):
        """
        Convert a string to the correct type for the propery.

        If failed, return False or (False, None). If success, return tuple
        (True, newValue).
        """
        try:
            val = int(st)
            return (True, val)
        except (ValueError, TypeError):
            pass
        except:
            raise
        return (False, None)

Since wx.propgrid.PGProperty derives from wx.Object, you can use standard DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS macros. From the above example they were omitted for sake of simplicity, and besides, they are only really needed if you need to use RTTI with your property class. You can change the ‘value type’ of a property by simply assigning different type of variant with SetValue. It is mandatory to implement VariantData class for all data types used as property values. You can use macros declared in wx.propgrid.PropertyGrid headers. For instance:

# NOTE: wxVariants are handled internally in wxPython. Conversions are
# implicitly done for those types that wxVariant already knows about, and
# the Raw PyObject is used for those that it doesn't know about.

Note

Uses int value, similar to wx.propgrid.EnumProperty, unless text entered by user is is not in choices (in which case string value is used).

A public C++ attribute of type ````. This member is public so scripting language bindings wrapper code can access it freely.


api Class API

class wx.propgrid.PGProperty(Object)

Possible constructors:

PGProperty()

PGProperty(label, name)

PGProperty is base class for all PropertyGrid properties and as such it is not intended to be instantiated directly.


Methods

AdaptListToValue(self, list, value)

Adapts list variant into proper value using consecutive ChildChanged calls.

Parameters
  • list (PGVariant) –

  • value (PGVariant) –



AddChoice(self, label, value=PG_INVALID_VALUE)

Append a new choice to property’s list of choices.

Parameters
  • label (string) – Label for added choice.

  • value (int) – Value for new choice. Do not specify if you wish this to equal choice index.

Return type

int

Returns

Index to added choice.



AddPrivateChild(self, prop)

Adds a private child property.

If you use this instead of wx.propgrid.PropertyGridInterface.Insert or wx.propgrid.PropertyGridInterface.AppendIn , then property’s parental type will automatically be set up to PG_PROP_AGGREGATE. In other words, all properties of this property will become private.

Parameters

prop (wx.propgrid.PGProperty) –



AppendChild(self, childProperty)

Use this member function to add independent (i.e.

regular) children to a property.

Parameters

childProperty (wx.propgrid.PGProperty) –

Return type

wx.propgrid.PGProperty

Returns

Appended childProperty.

Note

wx.propgrid.PropertyGrid is not automatically refreshed by this function.



AreAllChildrenSpecified(self, pendingList=None)

Determines, recursively, if all children are not unspecified.

Parameters

pendingList (PGVariant) – Assumes members in this Variant list as pending replacement values.

Return type

bool



AreChildrenComponents(self)

Returns True if children of this property are component values (for instance, points size, face name, and is_underlined are component values of a font).

Return type

bool



ChangeFlag(self, flag, set)

Sets or clears given property flag.

Mainly for internal use.

Parameters

Note

Setting a property flag never has any side-effect, and is intended almost exclusively for internal use. So, for example, if you want to disable a property, call

Enable(False)

instead of setting PG_PROP_DISABLED flag.

See also

HasFlag , GetFlags()



ChildChanged(self, thisValue, childIndex, childValue)

Called after value of a child property has been altered.

Must return new value of the whole property (after any alterations warranted by child’s new value).

Note that this function is usually called at the time that value of this property, or given child property, is still pending for change, and as such, result of GetValue or m_value should not be relied on.

Sample pseudo-code implementation:

# TBW
Parameters
  • thisValue (PGVariant) – Value of this property. Changed value should be returned (in previous versions of wx.propgrid.PropertyGrid it was only necessary to write value back to this argument).

  • childIndex (int) – Index of child changed (you can use Item(childIndex) to get child property).

  • childValue (PGVariant) – (Pending) value of the child property.

Return type

PGVariant

Returns

Modified value of the whole property.



DeleteChildren(self)

Deletes children of the property.



DeleteChoice(self, index)

Removes entry from property’s wx.propgrid.PGChoices and editor control (if it is active).

If selected item is deleted, then the value is set to unspecified.

Parameters

index (int) –



DoGetAttribute(self, name)

Returns value of an attribute.

Override if custom handling of attributes is needed.

Default implementation simply return None variant.

Parameters

name (string) –

Return type

PGVariant



DoGetEditorClass(self)

Returns pointer to an instance of used editor.

Return type

wx.propgrid.PGEditor



DoGetValidator(self)

Returns pointer to the wx.Validator that should be used with the editor of this property (None for no validator).

Setting validator explicitly via SetPropertyValidator will override this.

In most situations, code like this should work well (macros are used to maintain one actual validator instance, so on the second call the function exits within the first macro):

class MyPropertyClass(wx.propgrid.PGProperty):
    ...
    def DoGetValidator(self):
        validator = MyValidator(...)

        ... prepare validator...

        return validator
Return type

Validator

Note

You can get common filename validator by returning wx.propgrid.FileProperty.GetClassValidator . wx.propgrid.DirProperty, for example, uses it.



DoGetValue(self)

Override this to return something else than m_value as the value.

Return type

PGVariant



DoSetAttribute(self, name, value)

Reimplement this member function to add special handling for attributes of this property.

Parameters
  • name (string) –

  • value (PGVariant) –

Return type

bool

Returns

Return False to have the attribute automatically stored in m_attributes. Default implementation simply does that and nothing else.

Note

To actually set property attribute values from the application, use wx.propgrid.PGProperty.SetAttribute instead.



Enable(self, enable=True)

Enables or disables the property.

Disabled property usually appears as having grey text.

Parameters

enable (bool) – If False, property is disabled instead.



EnableCommonValue(self, enable=True)

Call to enable or disable usage of common value (integer value that can be selected for properties instead of their normal values) for this property.

Common values are disabled by the default for all properties.

Parameters

enable (bool) –



GenerateComposedValue(self)

Composes text from values of child properties.

Return type

string



GetAttribute(self, *args, **kw)

  • argFlags (int) – If PG_FULL_VALUE is set, returns complete, storable value instead of displayable one.

Return type

tuple

Returns

( bool, variant )

Note

  • If property is not supposed to use choice or spinctrl or other editor with int-based value, it is not necessary to implement this method.

  • Default implementation simply assign given int to m_value.

  • If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent.

  • You might want to take into account that m_value is Mull variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).



IsCategory(self)

Returns True if this property is actually a wx.propgrid.PropertyCategory.

Return type

bool



IsEnabled(self)

Returns True if property is enabled.

Return type

bool



IsExpanded(self)

Return type

bool



IsRoot(self)

Returns True if this property is actually a RootProperty.

Return type

bool



IsSomeParent(self, candidateParent)

Returns True if candidateParent is some parent of this property.

Use, for example, to detect if item is inside collapsed section.

Parameters

candidateParent (wx.propgrid.PGProperty) –

Return type

bool



IsSubProperty(self)

Returns True if this is a sub-property.

Return type

bool



IsTextEditable(self)

Returns True if property has editable wx.TextCtrl when selected.

Return type

bool

Note

Although disabled properties do not displayed editor, they still return True here as being disabled is considered a temporary condition (unlike being read-only or having limited editing enabled).



IsValueUnspecified(self)

Returns True if property’s value is considered unspecified.

This usually means that value is Null variant.

Return type

bool



IsVisible(self)

Returns True if all parents expanded.

Return type

bool



Item(self, i)

Returns child property at index i.

Parameters

i (int) –

Return type

wx.propgrid.PGProperty



Last(self)

Returns last sub-property.

Return type

wx.propgrid.PGProperty



OnCustomPaint(self, dc, rect, paintdata)

Override to paint an image in front of the property value text or drop-down list item (but only if wx.propgrid.PGProperty.OnMeasureImage is overridden as well).

If property’s OnMeasureImage returns size that has height != 0 but less than row height ( < 0 has special meanings), wx.propgrid.PropertyGrid calls this method to draw a custom image in a limited area in front of the editor control or value text/graphics, and if control has drop-down list, then the image is drawn there as well (even in the case OnMeasureImage returned higher height than row height).

NOTE: Following applies when OnMeasureImage returns a “flexible” height ( using PG_FLEXIBLE_SIZE(W,H) macro), which implies variable height items: If (rect.x+rect.width) is < 0, then this is a measure item call, which means that dc is invalid and only thing that should be done is to set paintdata.m_drawnHeight to the height of the image of item at index paintdata.m_choiceItem. This call may be done even as often as once every drop-down popup show.

Parameters

Note

  • You can actually exceed rect width, but if you do so then paintdata.m_drawnWidth must be set to the full width drawn in pixels.

  • Due to technical reasons, rect’s height will be default even if custom height was reported during measure call.

  • Brush is guaranteed to be default background colour. It has been already used to clear the background of area being painted. It can be modified.

  • Pen is guaranteed to be 1-wide ‘black’ (or whatever is the proper colour) pen for drawing framing rectangle. It can be changed as well.

ValueToString



OnEvent(self, propgrid, wnd_primary, event)

Events received by editor widgets are processed here.

Note that editor class usually processes most events. Some, such as button press events of TextCtrlAndButton class, can be handled here. Also, if custom handling for regular events is desired, then that can also be done (for example, wx.propgrid.SystemColourProperty custom handles wxEVT_CHOICE to display colour picker dialog when ‘custom’ selection is made).

If the event causes value to be changed, SetValueInEvent should be called to set the new value.

The parameter event is the associated wx.Event.

Parameters

return True if any changes in value should be reported.

Return type

bool

Note

  • If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent.



OnMeasureImage(self, item=-1)

Returns size of the custom painted image in front of property.

This method must be overridden to return non-default value if OnCustomPaint is to be called.

Parameters

item (int) – Normally -1, but can be an index to the property’s list of items.

Return type

Size

Note

  • Default behaviour is to return wx.Size, which means no image.

  • Default image width or height is indicated with dimension -1.

  • You can also return PG_DEFAULT_IMAGE_SIZE which equals DefaultSize.



OnSetValue(self)

This virtual function is called after m_value has been set.

Note

  • If m_value was set to Null variant (i.e. unspecified value), OnSetValue will not be called.

  • m_value may be of any variant type. Typically properties internally support only one variant type, and as such OnSetValue provides a good opportunity to convert supported values into internal type.

  • Default implementation does nothing.



OnValidationFailure(self, pendingValue)

Called whenever validation has failed with given pending value.

Parameters

pendingValue (PGVariant) –

Note

If you implement this in your custom property class, please remember to call the base implementation as well, since they may use it to revert property into pre-change state.



RecreateEditor(self)

If property’s editor is created this forces its recreation.

Useful in SetAttribute etc. Returns True if actually did anything.

Return type

bool



RefreshChildren(self)

Refresh values of child properties.

Automatically called after value is set.



RefreshEditor(self)

If property’s editor is active, then update it’s value.



SetAttribute(self, name, value)

Sets an attribute for this property.

Parameters
  • name (string) – Text identifier of attribute. See PropertyGrid Property Attribute Identifiers.

  • value (PGVariant) – Value of attribute.

Note

Setting attribute’s value to Null variant will simply remove it from property’s set of attributes.



SetAttributes(self, attributes)

Set the property’s attributes from a Python dictionary.



SetAutoUnspecified(self, enable=True)

Set if user can change the property’s value to unspecified by modifying the value of the editor control (usually by clearing it).

Currently, this can work with following properties: wx.propgrid.IntProperty, wx.propgrid.UIntProperty, wx.propgrid.FloatProperty, wx.propgrid.EditEnumProperty.

Parameters

enable (bool) – Whether to enable or disable this behaviour (it is disabled by default).



SetBackgroundColour(self, colour, flags=PG_RECURSE)

Sets property’s background colour.

Parameters
  • colour (wx.Colour) – Background colour to use.

  • flags (int) – Default is PG_RECURSE which causes colour to be set recursively. Omit this flag to only set colour for the property in question and not any of its children.

Note

Unlike wx.propgrid.PropertyGridInterface.SetPropertyBackgroundColour , this does not automatically update the display.



SetCell(self, column, cell)

Sets cell information for given column.

Parameters


SetChoiceSelection(self, newValue)

Sets selected choice and changes property value.

Tries to retain value type, although currently if it is not string, then it is forced to integer.

New in version 4.1/wxWidgets-3.1.0.

Note

Unlike wx.propgrid.PropertyGridInterface.SetPropertyColoursToDefault , this does not automatically update the display.

SetValue(self, value, pList=None, flags=PG_SETVAL_REFRESH_EDITOR)

Call this to set value of the property.

Unlike methods in wx.propgrid.PropertyGrid, this does not automatically update the display.

If you need to change property value in event, based on user input, use SetValueInEvent instead.

Parameters
  • value (PGVariant) – The value to set.

  • pList (PGVariant) – Pointer to list variant that contains child values. Used to indicate which children should be marked as modified. Usually you just use None.

  • flags (int) – PG_SETVAL_REFRESH_EDITOR is set by default, to refresh editor and redraw properties.

Use wx.propgrid.PropertyGrid.ChangePropertyValue instead if you need to run through validation process and send property change event.



SetValueFromInt(self, value, flags=0)

Converts integer to a value, and if successful, calls SetValue on it.

Default behaviour is to do nothing.

Parameters
  • value (long) – Int to get the value from.

Converts string to a value, and if successful, calls SetValue on it.

Default behaviour is to do nothing.

Parameters
  • text (string) – String to get the value from.

  • flags (int) – If PG_FULL_VALUE is set, the function sets complete, storable value instead of displayable one (they may be different). PG_PROGRAMMATIC_VALUE flag is used to indicate that value is being set programmatically (i.e. operation is not caused by user input). If PG_REPORT_ERROR is set, a special action should be performed if string couldn’t have been successfully converted to the valid value (e.g. a special value can be set in this case).

Return type

bool

Returns

True if value was changed.

bmp (wx.Bitmap) –



SetValueInEvent(self, value)

Call this function in OnEvent , OnButtonClick() etc.

to change the property value based on user input.

Parameters

value (PGVariant) –

SetValueToUnspecified(self)

Sets property’s value to unspecified (i.e.

Null variant).



SetWasModified(self, set=True)

Call with False in OnSetValue to cancel value changes after all (i.e.

cancel True returned by StringToValue or IntToValue ).

Parameters

set (bool) –



StringToValue(self, text, argFlags=0)

Converts text into Variant value appropriate for this property.

Parameters
  • text (string) – Text to be translated into variant.

  • argFlags (int) – If PG_FULL_VALUE is set, returns complete, storable value instead of displayable one (they may be different). If PG_COMPOSITE_FRAGMENT is set, text is interpreted as a part of composite property string value (as generated by ValueToString called with this same flag).

Return type

tuple

You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).

Returns

( bool, variant )

Note

Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.



UpdateParentValues(self)

Updates composed values of parent non-category properties, recursively.

Returns topmost property updated.

Return type

wx.propgrid.PGProperty

Note

Must not call SetValue (as can be called in it).

ValueToString(self, value, argFlags=0)

Converts property value into a text representation.

Parameters
  • value (PGVariant) – Value to be converted.

  • argFlags (int) – If 0 (default value), then displayed string is returned. If PG_FULL_VALUE is set, returns complete, storable string value instead of displayable. If PG_EDITABLE_VALUE is set, returns string value that must be editable in textctrl. If PG_COMPOSITE_FRAGMENT is set, returns text that is appropriate to display as a part of string property’s composite text representation.

Return type

string

Note

Default implementation calls GenerateComposedValue .



__init__(self, *args, **kw)

__init__ (self)

Default constructor.

It is protected because wx.propgrid.PGProperty is only a base class for other property classes.



__init__ (self, label, name)

Constructor.

It is protected because wx.propgrid.PGProperty is only a base class for other property classes. Non-abstract property classes should have constructor of this style:

class MyProperty(wx.propgrid.PGProperty):
    def __init__(self, label, name, value):
        wx.propgrid.PGProperty.__init__(self, label, name)
        self.SetValue(value)
Parameters
  • label (string) –

  • name (string) –
