The code for doing this has to be mixed up with the code that is invoked when an action is invoked for a menu item or button. ;With update UI events, you define an event handler to look at the state of the application and change UI elements accordingly. wxWidgets will call your member functions in idle time, so you dont have to worry where to call this code. In addition to being a clearer and more declarative method, it also means you dont have to worry whether youre updating a toolbar or menubar identifier. The same handler can update a menu item and toolbar button, if the identifier is the same. ;1.5 Popup Menu;2 工具栏 (ToolBar);3 静态控件;3.2 wxCheckBox ;wxCheckBox (wxWindow *parent, wxWindowID id, const wxString label, const wxPoint pos=wxDefaultPosition, const wxSize size=wxDefaultSize, long style=0, const wxValidator validator=wxDefaultValidator, const wxString name=wxCheckBoxNameStr) EVT_CHECKBOX(id, func):Process a wxEVT_CHECKBOX event, when the checkbox is clicked ;3.3 wxRadioBox;3.4 wxComboBox;EVT_COMBOBOX(id, func):Process a wxEVT_COMBOBOX event, when an item on the list is selected.
