wx.dataview.DataViewCtrl¶

wx.dataview.DataViewCtrl is a control to display data either in a tree like fashion or in a tabular form or both.

If you only need to display a simple tree structure with an API more like the older wx.TreeCtrl class, then the specialized wx.dataview.DataViewTreeCtrl can be used. Likewise, if you only want to display simple table structure you can use the specialized wx.dataview.DataViewListCtrl class. Both wx.dataview.DataViewTreeCtrl and wx.dataview.DataViewListCtrl can be used without defining your own wx.dataview.DataViewModel.

A wx.dataview.DataViewItem is used to represent a (visible) item in the control.

Unlike wx.ListCtrl, wx.dataview.DataViewCtrl doesn’t get its data from the user through virtual functions or by setting it directly. Instead you need to write your own wx.dataview.DataViewModel and associate it with this control. Then you need to add a number of wx.dataview.DataViewColumn to this control to define what each column shall display. Each wx.dataview.DataViewColumn in turn owns 1 instance of a wx.dataview.DataViewRenderer to render its cells.

A number of standard renderers for rendering text, dates, images, toggle, a progress bar etc. are provided. Additionally, the user can write custom renderers deriving from wx.dataview.DataViewCustomRenderer for displaying anything.

All data transfer from the control to the model and the user code is done through Variant which can be extended to support more data formats as necessary. Accordingly, all type information uses the strings returned from Variant.GetType .

This control supports single column sorting and on some platforms (currently only those using the generic version, i.e. not wxGTK nor wxOSX) also sorting by multiple columns at once. The latter must be explicitly enabled using AllowMultiColumnSort, which will also indicate whether this feature is supported, as it changes the default behaviour of right clicking the column header to add or remove it to the set of columns used for sorting. If this behaviour is not appropriate, you may handle wxEVT_DATAVIEW_COLUMN_HEADER_RIGHT_CLICK event yourself to prevent it from happening. In this case you would presumably call ToggleSortByColumn from some other event handler to still allow the user to configure sort order somehow.

Window Styles¶

This class supports the following styles:

wx.dataview.DV_SINGLE: Single selection mode. This is the default.
wx.dataview.DV_MULTIPLE: Multiple selection mode.
wx.dataview.DV_ROW_LINES: Use alternating colours for odd and even rows.
wx.dataview.DV_HORIZ_RULES: Display the separator lines between rows.
wx.dataview.DV_VERT_RULES: Display the separator lines between columns.
wx.dataview.DV_VARIABLE_LINE_HEIGHT: Allow variable line heights. This can be inefficient when displaying large number of items.
wx.dataview.DV_NO_HEADER: Do not show column headers (which are shown by default). ^^

^^

Events Emitted by this Class¶

Handlers bound for the following event types will receive a wx.dataview.DataViewEvent parameter.

EVT_DATAVIEW_SELECTION_CHANGED: Process a wxEVT_DATAVIEW_SELECTION_CHANGED event.
EVT_DATAVIEW_ITEM_ACTIVATED: Process a wxEVT_DATAVIEW_ITEM_ACTIVATED event. This event is triggered by double clicking an item or pressing some special key (usually “Enter”) when it is focused.
EVT_DATAVIEW_ITEM_START_EDITING: Process a wxEVT_DATAVIEW_ITEM_START_EDITING event. This event can be vetoed in order to prevent editing on an item by item basis.
EVT_DATAVIEW_ITEM_EDITING_STARTED: Process a wxEVT_DATAVIEW_ITEM_EDITING_STARTED event.
EVT_DATAVIEW_ITEM_EDITING_DONE: Process a wxEVT_DATAVIEW_ITEM_EDITING_DONE event.
EVT_DATAVIEW_ITEM_COLLAPSING: Process a wxEVT_DATAVIEW_ITEM_COLLAPSING event.
EVT_DATAVIEW_ITEM_COLLAPSED: Process a wxEVT_DATAVIEW_ITEM_COLLAPSED event.
EVT_DATAVIEW_ITEM_EXPANDING: Process a wxEVT_DATAVIEW_ITEM_EXPANDING event.
EVT_DATAVIEW_ITEM_EXPANDED: Process a wxEVT_DATAVIEW_ITEM_EXPANDED event.
EVT_DATAVIEW_ITEM_VALUE_CHANGED: Process a wxEVT_DATAVIEW_ITEM_VALUE_CHANGED event.
EVT_DATAVIEW_ITEM_CONTEXT_MENU: Process a wxEVT_DATAVIEW_ITEM_CONTEXT_MENU event generated when the user right clicks inside the control. Notice that this menu is generated even if the click didn’t occur on any valid item, in this case wx.dataview.DataViewEvent.GetItem simply returns an invalid item.
EVT_DATAVIEW_COLUMN_HEADER_CLICK: Process a wxEVT_DATAVIEW_COLUMN_HEADER_CLICK event.
EVT_DATAVIEW_COLUMN_HEADER_RIGHT_CLICK: Process a wxEVT_DATAVIEW_COLUMN_HEADER_RIGHT_CLICK event.
EVT_DATAVIEW_COLUMN_SORTED: Process a wxEVT_DATAVIEW_COLUMN_SORTED event.
EVT_DATAVIEW_COLUMN_REORDERED: Process a wxEVT_DATAVIEW_COLUMN_REORDERED event.
EVT_DATAVIEW_ITEM_BEGIN_DRAG: Process a wxEVT_DATAVIEW_ITEM_BEGIN_DRAG event which is generated when the user starts dragging a valid item. This event must be processed and wx.dataview.DataViewEvent.SetDataObject must be called to actually start dragging the item.
EVT_DATAVIEW_ITEM_DROP_POSSIBLE: Process a wxEVT_DATAVIEW_ITEM_DROP_POSSIBLE event.
EVT_DATAVIEW_ITEM_DROP: Process a wxEVT_DATAVIEW_ITEM_DROP event. ^^

Notice that this control doesn’t allow to process generic mouse events such as: wxEVT_LEFT_DOWN in all ports (notably it doesn’t work in wxGTK). If you need to handle any mouse events not covered by the ones above, consider using a custom renderer for the cells that must handle them.

Note

Under wxMSW this control uses SystemThemedControl for an explorer style appearance by default since wxWidgets 3.1.0. If this is not desired, you can call SystemThemedControl.EnableSystemTheme with false argument to disable this.

Removes all columns.

Return type:: bool

Collapse(self, item)¶

Collapses the item.

Parameters:: item (wx.dataview.DataViewItem) –

Create(self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=0, validator=DefaultValidator, name=DataViewCtrlNameStr)¶

Create the control.

Useful for two step creation.

Parameters:

id (wx.WindowID) –
pos (wx.Point) –
size (wx.Size) –
style (long) –
validator (wx.Validator) –
name (string) –

Return type:

bool

DeleteColumn(self, column)¶

Deletes given column.

Parameters:: column (wx.dataview.DataViewColumn) –
Return type:: bool

EditItem(self, item, column)¶

Programmatically starts editing given cell of item.

Doesn’t do anything if the item or this column is not editable.

Parameters:

item (wx.dataview.DataViewItem) –
column (wx.dataview.DataViewColumn) –

New in version 2.9.4.

EnableDragSource(self, format)¶

Enable drag operations using the given format.

Parameters:: format (wx.DataFormat) –
Return type:: bool

EnableDropTarget(self, format)¶

Enable drop operations using the given format.

See EnableDropTargets for providing more than one supported format.

Parameters:: format (wx.DataFormat) –
Return type:: bool

Note

Since 3.1.6 wx.DF_INVALID can be passed to disable drag and drop support.

EnableDropTargets(self, formats)¶

Enable drop operations using any of the specified formats.

Currently this is fully implemented in the generic and native macOS versions. In wxGTK only the first element of the array is used.

Parameters:: formats (Vector) –
Return type:: bool

New in version 4.1/wxWidgets-3.1.6.

Note

Passing empty array disables drag and drop operations completely.

EnableSystemTheme(self, enable=True)¶

Can be used to disable the system theme of controls using it by default.

On Windows there an alternative theme available for the list and list-like controls since Windows Vista. This theme is used by Windows Explorer list and tree view and so is arguably more familiar to the users than the standard appearance of these controls. This class automatically uses the new theme, but if that is not desired then this method can be used to turn it off.

Please note that this method should be called before the widget is actually created, using the 2-phase create pattern. Something like this:

# This creates the object, but not the window
widget = wx.dataview.DataViewCtrl()

# Disable the system theme
widget.EnableSystemTheme(False)

# Now create the window
widget.Create(parent, wx.``wx.ID_ANY``)

This method has no effect on other platorms

Parameters:: enable (bool) –

EnsureVisible(self, item, column=None)¶

Call this to ensure that the given item is visible.

Parameters:

item (wx.dataview.DataViewItem) –
column (wx.dataview.DataViewColumn) –

Expand(self, item)¶

Expands the item.

Parameters:: item (wx.dataview.DataViewItem) –

ExpandAncestors(self, item)¶

Expands all ancestors of the item.

This method also ensures that the item itself as well as all ancestor items have been read from the model by the control.

Parameters:: item (wx.dataview.DataViewItem) –

ExpandChildren(self, item)¶

Expand all children of the given item recursively.

This is the same as calling Expand on the item itself and then calling it for all of its children, grandchildren etc recursively.

Parameters:: item (wx.dataview.DataViewItem) –

New in version 4.1/wxWidgets-3.1.5.

static GetClassDefaultAttributes(variant=WINDOW_VARIANT_NORMAL)¶

Return type:: int

New in version 4.1/wxWidgets-3.1.1.

GetCurrentColumn(self)¶

Returns the column that currently has focus.
