For instance, collapsing a parent property programmatically causes any selected child property to become unselected, and may therefore cause this event to be generated. @event{EVT_PG_CHANGED(id, func)} Respond to @c wxEVT_PG_CHANGED event, generated when property value has been changed by the user. @event{EVT_PG_CHANGING(id, func)} Respond to @c wxEVT_PG_CHANGING event, generated when property value is about to be changed by user. Use wxPropertyGridEvent::GetValue() to take a peek at the pending value, and wxPropertyGridEvent::Veto() to prevent change from taking place, if necessary. @event{EVT_PG_HIGHLIGHTED(id, func)} Respond to @c wxEVT_PG_HIGHLIGHTED event, which occurs when mouse moves over a property. Event's property is @NULL if hovered area does not belong to any property. @event{EVT_PG_RIGHT_CLICK(id, func)} Respond to @c wxEVT_PG_RIGHT_CLICK event, which occurs when property is clicked on with right mouse button. @event{EVT_PG_DOUBLE_CLICK(id, func)} Respond to @c wxEVT_PG_DOUBLE_CLICK event, which occurs when property is double-clicked on with left mouse button. @event{EVT_PG_ITEM_COLLAPSED(id, func)} Respond to @c wxEVT_PG_ITEM_COLLAPSED event, generated when user collapses a property or category. @event{EVT_PG_ITEM_EXPANDED(id, func)} Respond to @c wxEVT_PG_ITEM_EXPANDED event, generated when user expands a property or category. @event{EVT_PG_LABEL_EDIT_BEGIN(id, func)} Respond to @c 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. @event{EVT_PG_LABEL_EDIT_ENDING(id, func)} Respond to @c 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. @event{EVT_PG_COL_BEGIN_DRAG(id, func)} Respond to @c wxEVT_PG_COL_BEGIN_DRAG event, generated when user starts resizing a column - can be vetoed. @event{EVT_PG_COL_DRAGGING,(id, func)} Respond to @c 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. @event{EVT_PG_COL_END_DRAG(id, func)} Respond to @c wxEVT_PG_COL_END_DRAG event, generated after column resize by user has finished. @endEventTable @remarks Use Freeze() and Thaw() respectively to disable and enable drawing.
