wxTreebookEvent

Задать вопрос на форуме...

This class represents the events generated by a treebook control: currently, there are four of them. The PAGE_CHANGING and PAGE_CHANGED - have exactly the same behaviour as wxNotebookEvent.

The other two NODE_COLLAPSED and NODE_EXPANDED are triggered when page node in the tree control is collapsed/expanded. The page index could be retreived by calling wxTreebookEvent::GetSelection.

Derived from

wxBookCtrlBaseEvent
wxNotifyEvent
wxCommandEvent

Event handling

To process input from a treebook control, use the following event handler macros to direct input to member functions that take a wxTreebookEvent argument.

EVT_TREEBOOK_PAGE_CHANGED(id, func)	The page selection was changed. Processes a wxEVT_COMMAND_TREEBOOK_PAGE_CHANGED event.
EVT_TREEBOOK_PAGE_CHANGING(id, func)	The page selection is about to be changed. Processes a wxEVT_COMMAND_TREEBOOK_PAGE_CHANGING event. This event can be vetoed.
EVT_TREEBOOK_NODE_COLLAPSED(id, func)	The page node is going to be collapsed. Processes a wxEVT_COMMAND_TREEBOOK_NODE_COLLAPSED event.
EVT_TREEBOOK_NODE_EXPANDED(id, func)	The page node is going to be expanded. Processes a wxEVT_COMMAND_TREEBOOK_NODE_EXPANDED event.
