A frame is a window which contains subwindows of various kinds. It has a title bar and, optionally, a menu bar, and a status line. Depending on the platform, the frame has further menus or buttons relating to window movement, sizing, closing, etc. Most of these events are handled by the host system without need for special handling by the application. However, the application should normally define an wxFrame::OnClose handler for the frame so that related data and subwindows can be cleaned up.
The Windows 3 issues of Multiple Document Interface (MDI) versus Single Document Interface (SDI) frames are covered in the user manual.
A frame may contain the subwindows wxCanvas, wxPanel and wxTextWindow.
