|api| Class API
===============
.. class:: wx.propgrid.PropertyGridEvent(CommandEvent)
**Possible constructors**::
PropertyGridEvent(commandType=0, id=0)
PropertyGridEvent(event)
A property grid event holds information about events associated with
PropertyGrid objects.
.. method:: __init__(self, *args, **kw)
|overload| Overloaded Implementations:
:html:`<hr class="overloadsep" /><br />`
**__init__** `(self, commandType=0, id=0)`
Constructor.
:param `commandType`:
:type `commandType`: wx.EventType
:param `id`:
:type `id`: int
:html:`<hr class="overloadsep" /><br />`
**__init__** `(self, event)`
Copy constructor.
:param `event`:
:type `event`: wx.propgrid.PropertyGridEvent
:html:`<hr class="overloadsep" /><br />`
.. 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.
.. seealso:: :meth:`GetPropertyValue`
.. method:: GetValidationFailureBehavior(self)
Returns current validation failure flags.
:rtype: `wx.propgrid.PGVFBFlags`
.. 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.propgrid.PGVFBFlags
.. method:: SetValidationFailureMessage(self, message)
Sets custom failure message for this time only.
Only applies if ``wx.propgrid.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`
