To process input from a property grid control, use these event handler macros to direct input to member functions that take a :ref:`wx.propgrid.PropertyGridEvent` argument. ^^ .. _PropertyGridEvent-events: |events| Events Emitted by this Class ===================================== Handlers bound for the following event types will receive a :ref:`wx.propgrid.PropertyGridEvent` parameter. - ``EVT_PG_SELECTED`` : Respond to ``wxEVT_PG_SELECTED`` event, generated when a property selection has been changed, either by user action or by indirect program function. For instance, collapsing a parent property programmatically causes any selected child property to become unselected, and may therefore cause this event to be generated. - EVT_PG_CHANGED: Respond to ``wxEVT_PG_CHANGED`` event, generated when property value has been changed by the user. - EVT_PG_CHANGING: Respond to ``wxEVT_PG_CHANGING`` event, generated when property value is about to be changed by user. Use :meth:`wx.propgrid.PropertyGridEvent.GetValue` to take a peek at the pending value, and :meth:`wx.propgrid.PropertyGridEvent.Veto` to prevent change from taking place, if necessary. - EVT_PG_HIGHLIGHTED: Respond to ``wxEVT_PG_HIGHLIGHTED`` event, which occurs when mouse moves over a property. Event's property is ``None`` if hovered area does not belong to any property. - EVT_PG_RIGHT_CLICK: Respond to ``wxEVT_PG_RIGHT_CLICK`` event, which occurs when property is clicked on with right mouse button. - EVT_PG_DOUBLE_CLICK: Respond to ``wxEVT_PG_DOUBLE_CLICK`` event, which occurs when property is double-clicked on with left mouse button. - EVT_PG_ITEM_COLLAPSED: Respond to ``wxEVT_PG_ITEM_COLLAPSED`` event, generated when user collapses a property or category. - EVT_PG_ITEM_EXPANDED: Respond to ``wxEVT_PG_ITEM_EXPANDED`` event, generated when user expands a property or category. - EVT_PG_LABEL_EDIT_BEGIN: Respond to ``wxEVT_PG_LABEL_EDIT_BEGIN`` event, generated when user is about to begin editing a property label. You can veto this event to prevent the action. - EVT_PG_LABEL_EDIT_ENDING: Respond to ``wxEVT_PG_LABEL_EDIT_ENDING`` event, generated when user is about to end editing of a property label. You can veto this event to prevent the action. - EVT_PG_COL_BEGIN_DRAG: Respond to ``wxEVT_PG_COL_BEGIN_DRAG`` event, generated when user starts resizing a column - can be vetoed. - ``EVT_PG_COL_DRAGGING``, : Respond to ``wxEVT_PG_COL_DRAGGING`` , event, generated when a column resize by user is in progress. This event is also generated when user double-clicks the splitter in order to recenter it. - EVT_PG_COL_END_DRAG: Respond to ``wxEVT_PG_COL_END_DRAG`` event, generated after column resize by user has finished. ^^ | |class_hierarchy| Class Hierarchy ================================= .. raw:: html

` **__init__** `(self, commandType=0, id=0)` Constructor. :param `commandType`: :type `commandType`: wx.EventType :param `id`: :type `id`: int :html:`

` .. method:: CanVeto(self) Returns ``True`` if you can veto the action that the event is signaling. :rtype: `bool` .. method:: GetColumn(self) Returns the column index associated with this event. For the column dragging events, it is the column to the left of the splitter being dragged :rtype: `int` .. method:: GetMainParent(self) Returns highest level non-category, non-root parent of property for which event occurred. Useful when you have nested properties with children. :rtype: :ref:`wx.propgrid.PGProperty` .. note:: If immediate parent is root or category, this will return the property itself. .. method:: GetProperty(self) Returns property associated with this event. :rtype: :ref:`wx.propgrid.PGProperty` .. note:: You should assume that this property can always be ``None``. For instance, ``wxEVT_PG_SELECTED`` is emitted not only when a new property is selected, but also when selection is cleared by user activity. .. method:: GetPropertyName(self) Returns name of the associated property. :rtype: `string` .. note:: Property name is stored in event, so it remains accessible even after the associated property or the property grid has been deleted. .. method:: GetPropertyValue(self) Returns value of the associated property. Works for all event types, but for ``wxEVT_PG_CHANGING`` this member function returns the value that is pending, so you can call :meth:`Veto` if the value is not satisfactory. :rtype: `PGVariant` .. note:: Property value is stored in event, so it remains accessible even after the associated property or the property grid has been deleted. .. method:: GetValidationFailureBehavior(self) Returns current validation failure flags. :rtype: `wx.byte` .. method:: GetValue(self) Returns value of the associated property. :rtype: `PGVariant` .. seealso:: :meth:`GetPropertyValue` .. method:: SetCanVeto(self, canVeto) Set if event can be vetoed. :param `canVeto`: :type `canVeto`: bool .. method:: SetProperty(self, p) Changes the property associated with this event. :param `p`: :type `p`: wx.propgrid.PGProperty .. method:: SetValidationFailureBehavior(self, flags) Set override validation failure behaviour. Only effective if :meth:`Veto` was also called, and only allowed if event type is ``wxEVT_PG_CHANGING`` . :param `flags`: :type `flags`: wx.byte .. method:: SetValidationFailureMessage(self, message) Sets custom failure message for this time only. Only applies if ``PG_VFB_SHOW_MESSAGE`` is set in validation failure flags. :param `message`: :type `message`: string .. method:: Veto(self, veto=True) Call this from your event handler to veto action that the event is signaling. You can only veto a shutdown if :meth:`wx.propgrid.PropertyGridEvent.CanVeto` returns ``True``. :param `veto`: :type `veto`: bool .. note:: Currently only ``wxEVT_PG_CHANGING`` supports vetoing. .. method:: WasVetoed(self) Returns ``True`` if event was vetoed. :rtype: `bool` .. attribute:: Column See :meth:`~wx.propgrid.PropertyGridEvent.GetColumn` .. attribute:: MainParent See :meth:`~wx.propgrid.PropertyGridEvent.GetMainParent` .. attribute:: Property See :meth:`~wx.propgrid.PropertyGridEvent.GetProperty` and :meth:`~wx.propgrid.PropertyGridEvent.SetProperty` .. attribute:: PropertyName See :meth:`~wx.propgrid.PropertyGridEvent.GetPropertyName` .. attribute:: PropertyValue See :meth:`~wx.propgrid.PropertyGridEvent.GetPropertyValue` .. attribute:: ValidationFailureBehavior See :meth:`~wx.propgrid.PropertyGridEvent.GetValidationFailureBehavior` and :meth:`~wx.propgrid.PropertyGridEvent.SetValidationFailureBehavior` .. attribute:: Value See :meth:`~wx.propgrid.PropertyGridEvent.GetValue`
