 553 /** @class wxPropertyGrid
 554
 555     wxPropertyGrid is a specialized grid for editing properties
 556     such as strings, numbers, flagsets, fonts, and colours. wxPropertySheet
 557     used to do the very same thing, but it hasn't been updated for a while
 558     and it is currently deprecated.
 559
 560     Please note that most member functions are inherited and as such not
 561     documented on this page. This means you will probably also want to read
 562     wxPropertyGridInterface class reference.

 569
 570     @section propgrid_event_handling Event Handling
 571
 572     To process input from a propertygrid control, use these event handler
 573     macros to direct input to member functions that take a wxPropertyGridEvent
 574     argument.
 575
 576     @beginEventTable{wxPropertyGridEvent}
 577     @event{EVT_PG_SELECTED (id, func)}
 578         Respond to wxEVT_PG_SELECTED event, generated when a property selection
 579         has been changed, either by user action or by indirect program
 580         function. For instance, collapsing a parent property programmatically
 581         causes any selected child property to become unselected, and may
 582         therefore cause this event to be generated.
 583     @event{EVT_PG_CHANGING(id, func)}
 584         Respond to wxEVT_PG_CHANGING event, generated when property value
 585         is about to be changed by user. Use wxPropertyGridEvent::GetValue()
 586         to take a peek at the pending value, and wxPropertyGridEvent::Veto()
 587         to prevent change from taking place, if necessary.
 588     @event{EVT_PG_HIGHLIGHTED(id, func)}
 589         Respond to wxEVT_PG_HIGHLIGHTED event, which occurs when mouse
 590         moves over a property. Event's property is NULL if hovered area does
 591         not belong to any property.
 592     @event{EVT_PG_RIGHT_CLICK(id, func)}
 593         Respond to wxEVT_PG_RIGHT_CLICK event, which occurs when property is
 594         clicked on with right mouse button.
 595     @event{EVT_PG_DOUBLE_CLICK(id, func)}
 596         Respond to wxEVT_PG_DOUBLE_CLICK event, which occurs when property is
 597         double-clicked onwith left mouse button.
 598     @event{EVT_PG_ITEM_COLLAPSED(id, func)}
 599         Respond to wxEVT_PG_ITEM_COLLAPSED event, generated when user collapses
 600         a property or category..
 601     @event{EVT_PG_ITEM_EXPANDED(id, func)}
 602         Respond to wxEVT_PG_ITEM_EXPANDED event, generated when user expands
 603         a property or category..
 604     @event{EVT_PG_LABEL_EDIT_BEGIN(id, func)}
 605         Respond to wxEVT_PG_LABEL_EDIT_BEGIN event, generated when is about to
 606         begin editing a property label. You can veto this event to prevent the
 607         action.
 608     @event{EVT_PG_LABEL_EDIT_ENDING(id, func)}
 609         Respond to wxEVT_PG_LABEL_EDIT_ENDING event, generated when is about to
 610         end editing of a property label. You can veto this event to prevent the
 611         action.
 612     @endEventTable
 613
 614     @remarks
 615
 616     - Use Freeze() and Thaw() respectively to disable and enable drawing. This
 617       will also delay sorting etc. miscellaneous calculations to the last
 618       possible moment.
