wx.propgrid.UIntProperty¶Basic property with integer value.
Seamlessly supports 64-bit integer (ULongLong ) on overflow.
Supported special attributes:
PG_UINT_BASE: Define 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: 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_MIN, PG_ATTR_MAX, PG_ATTR_SPINCTRL_STEP, PG_ATTR_SPINCTRL_WRAP, PG_ATTR_SPINCTRL_MOTION: like in wx.propgrid.NumericProperty.
Note
For example how to use seamless 64-bit integer support, see wx.propgrid.IntProperty documentation (just use ULongLong instead of LongLong ).

Class API¶
wx.propgrid.UIntProperty(NumericProperty)¶Possible constructors:
UIntProperty(label=PG_LABEL, name=PG_LABEL, value=0)
UIntProperty(label, name, value)
Basic property with integer value.
__init__(self, *args, **kw)¶
Overloaded Implementations:
__init__ (self, label=PG_LABEL, name=PG_LABEL, value=0)
label (string) –
name (string) –
value (long) –
__init__ (self, label, name, value)
label (string) –
name (string) –
value (ULongLong) –
AddSpinStepValue(self, stepScale)¶Returns what would be the new value of the property after adding SpinCtrl editor step to the current value.
Current value range and wrapping (if enabled) are taken into account. This member has to be implemented in derived properties.
stepScale (long) – SpinCtrl editor step is first multiplied by this factor and next added to the current value.
PGVariant
Value which property would have after adding SpinCtrl editor step.
Note
Current property value is not changed.
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.UIntProperty):
...
def DoGetValidator(self):
validator = MyValidator(...)
... prepare validator...
return validator
Validator
Note
You can get common filename validator by returning wx.propgrid.FileProperty.GetClassValidator . wx.propgrid.DirProperty, for example, uses it.
DoSetAttribute(self, name, value)¶Reimplement this member function to add special handling for attributes of this property.
name (string) –
value (PGVariant) –
bool
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.
IntToValue(self, number, argFlags=0)¶Converts integer (possibly a choice selection) into Variant value appropriate for this property.
number (int) – Integer to be translated into variant.
argFlags (int) – If PG_FULL_VALUE is set, returns complete, storable value instead of displayable one.
tuple
( 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).
StringToValue(self, text, argFlags=0)¶Converts text into Variant value appropriate for this property.
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).
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).
( bool, variant )
Note
Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.
ValidateValue(self, value, validationInfo)¶Implement this function in derived class to check the value.
Return True if it is ok. Returning False prevents property change events from occurring.
value (PGVariant) –
validationInfo (wx.propgrid.PGValidationInfo) –
bool
Note
Default implementation always returns True.
ValueToString(self, value, argFlags=0)¶Converts property value into a text representation.
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.
string
Note
Default implementation calls GenerateComposedValue .
