 517 /** @class wxPropertyGrid
 518
 519     wxPropertyGrid is a specialized grid for editing properties
 520     such as strings, numbers, flagsets, fonts, and colours. wxPropertySheet
 521     used to do the very same thing, but it hasn't been updated for a while
 522     and it is currently deprecated.
 523
 524     Please note that most member functions are inherited and as such not
 525     documented on this page. This means you will probably also want to read
 526     wxPropertyGridInterface class reference.

 533
 534     @section propgrid_event_handling Event Handling
 535
 536     To process input from a propertygrid control, use these event handler
 537     macros to direct input to member functions that take a wxPropertyGridEvent
 538     argument.
 539
 540     @beginEventTable{wxPropertyGridEvent}
 541     @event{EVT_PG_SELECTED (id, func)}
 542         Respond to wxEVT_PG_SELECTED event, generated when property value
 543         has been changed by user.
 544     @event{EVT_PG_CHANGING(id, func)}
 545         Respond to wxEVT_PG_CHANGING event, generated when property value
 546         is about to be changed by user. Use wxPropertyGridEvent::GetValue()
 547         to take a peek at the pending value, and wxPropertyGridEvent::Veto()
 548         to prevent change from taking place, if necessary.
 549     @event{EVT_PG_HIGHLIGHTED(id, func)}
 550         Respond to wxEVT_PG_HIGHLIGHTED event, which occurs when mouse
 551         moves over a property. Event's property is NULL if hovered area does
 552         not belong to any property.
 553     @event{EVT_PG_RIGHT_CLICK(id, func)}
 554         Respond to wxEVT_PG_RIGHT_CLICK event, which occurs when property is
 555         clicked on with right mouse button.
 556     @event{EVT_PG_DOUBLE_CLICK(id, func)}
 557         Respond to wxEVT_PG_DOUBLE_CLICK event, which occurs when property is
 558         double-clicked onwith left mouse button.
 559     @event{EVT_PG_ITEM_COLLAPSED(id, func)}
 560         Respond to wxEVT_PG_ITEM_COLLAPSED event, generated when user collapses
 561         a property or category..
 562     @event{EVT_PG_ITEM_EXPANDED(id, func)}
 563         Respond to wxEVT_PG_ITEM_EXPANDED event, generated when user expands
 564         a property or category..
 565     @endEventTable
 566
 567     @remarks
 568
 569     - Use Freeze() and Thaw() respectively to disable and enable drawing. This
 570       will also delay sorting etc. miscellaneous calculations to the last
 571       possible moment.
