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. @library{wxcore} @category{events} @see wxNotebookEvent, wxTreebook */ class wxTreebookEvent : public wxNotifyEvent { public: /** @see wxNotebookEvent */ wxTreebookEvent(wxEventType commandType = wxEVT_NULL, int id = 0, int nSel = wxNOT_FOUND, int nOldSel = wxNOT_FOUND); /** Returns the page that was selected before the change, wxNOT_FOUND if none was selected. */ int GetOldSelection() const; /** Returns the currently selected page, or wxNOT_FOUND if none was selected. */ int GetSelection() const; }; /** @class wxTreebook @wxheader{treebook.h} This class is an extension of the Notebook class that allows a tree structured set of pages to be shown in a control. A classic example is a netscape preferences dialog that shows a tree of preference sections on the left and select section page on the right. To use the class simply create it and populate with pages using wxTreebook::InsertPage, wxTreebook::InsertSubPage, wxTreebook::AddPage, wxTreebook::AddSubPage. If your tree is no more than 1 level in depth then you could simply use wxTreebook::AddPage and wxTreebook::AddSubPage to sequentially populate your tree by adding at every step a page or a subpage to the end of the tree. @library{wxcore} @category{miscwnd} @see wxNotebook, wxTreebookEvent, wxImageList, @ref overview_samplenotebook "notebook sample" */ class wxTreebook : public wxBookCtrl overview { public: //@{ /** Creates an empty TreeBook control. @param parent The parent window.
