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

59either the windowing system or wxWidgets, depending on platform.}

91\membersection{wxPanel::InitDialog}\label{wxpanelinitdialog}
92
93\func{void}{InitDialog}{\void}
94
95Sends a \helpref{wxInitDialogEvent}{wxinitdialogevent}, which
96in turn transfers data to the dialog via validators.

103
104\func{void}{OnSysColourChanged}{\param{wxSysColourChangedEvent\& }{event}}
105
106The default handler for wxEVT\_SYS\_COLOUR\_CHANGED.
107
108\wxheading{Parameters}
109
110\docparam{event}{The colour change event.}
111
112\wxheading{Remarks}
113
114Changes the panel's colour to conform to the current settings (Windows only).
115Add an event table entry for your panel class if you wish the behaviour
116to be different (such as keeping a user-defined
117background colour). If you do override this function, call wxEvent::Skip to
118propagate the notification to child windows and controls.

125\membersection{wxPanel::SetFocus}\label{wxpanelsetfocus}
126
127\func{virtual void}{SetFocus}{\void}
128
129Overrides \helpref{wxWindow::SetFocus}{wxwindowsetfocus}. This method
130uses the (undocumented) mix-in class wxControlContainer which manages
131the focus and TAB logic for controls which usually have child controls.
132In practice, if you call this method and the control has at least
133one child window, the focus will be given to the child window.

142
143\func{virtual void}{SetFocusIgnoringChildren}{\void}
144
145In contrast to \helpref{wxPanel::SetFocus}{wxpanelsetfocus} (see above)
146this will set the focus to the panel even of there are child windows
147in the panel. This is only rarely needed.
