Remarks

Although internally an MDI child frame is a child of the MDI client window, in wxWidgets you create it as a child of wxMDIParentFrame. You can usually forget that the client window exists.

MDI child frames are clipped to the area of the MDI client window, and may be iconized on the client window.

You can associate a menubar with a child frame as usual, although an MDI child doesn't display its menubar under its own title bar. The MDI parent frame's menubar will be changed to reflect the currently active child frame. If there are currently no children, the parent frame's own menubar will be displayed.

### wxMDIChildFrame::wxMDIChildFrame

wxMDIChildFrame()

Default constructor.

wxMDIChildFrame(wxMDIParentFrame* parent, wxWindowID id, const wxString& title, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxDEFAULT_FRAME_STYLE, const wxString& name = "frame")
