   1 \section{\class{wxPanel}}\label{wxpanel}
   2
   3 A panel is a window on which controls are placed. It is usually placed within a frame.
   4 It contains minimal extra functionality over and above its parent class wxWindow; its main
   5 purpose is to be similar in appearance and functionality to a dialog, but with the flexibility of
   6 having any window as a parent.
   7
   8 {\it Note:} if not all characters are being intercepted by your OnKeyDown or OnChar handler,
   9 it may be because you are using the wxTAB\_TRAVERSAL style, which grabs some keypresses for use
  10 by child controls.

 101
 102 \func{void}{InitDialog}{\void}
 103
 104 Sends an \helpref{wxWindow::OnInitDialog}{wxwindowoninitdialog} event, which
 105 in turn transfers data to the dialog via validators.

 124 Add an event table entry for your panel class if you wish the behaviour
 125 to be different (such as keeping a user-defined
 126 background colour). If you do override this function, call \helpref{wxWindow::OnSysColourChanged}{wxwindowonsyscolourchanged} to
 127 propagate the notification to child windows and controls.
