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. | |

55 | ||
56 | \docparam{id}{An identifier for the panel. A value of -1 is taken to mean a default.} | |
57 | ||
58 | \docparam{pos}{The panel position. A value of (-1, -1) indicates a default position, chosen by | |
59 | either the windowing system or wxWidgets, depending on platform.} | |

91 | \membersection{wxPanel::GetDefaultItem}\label{wxpanelgetdefaultitem} | |
92 | ||
93 | \constfunc{wxWindow*}{GetDefaultItem}{\void} | |
94 | ||
95 | Returns a pointer to the button which is the default for this window, or NULL. | |
96 | The default button is the one activated by pressing the Enter key. | |

99 | ||
100 | \func{void}{InitDialog}{\void} | |
101 | ||
102 | Sends a \helpref{wxInitDialogEvent}{wxinitdialogevent}, which | |
103 | in turn transfers data to the dialog via validators. | |

110 | ||
111 | \func{void}{OnSysColourChanged}{\param{wxSysColourChangedEvent\& }{event}} | |
112 | ||
113 | The default handler for wxEVT\_SYS\_COLOUR\_CHANGED. | |
114 | ||
115 | \wxheading{Parameters} | |
116 | ||
117 | \docparam{event}{The colour change event.} | |
118 | ||
119 | \wxheading{Remarks} | |
120 | ||
121 | Changes the panel's colour to conform to the current settings (Windows only). | |
122 | Add an event table entry for your panel class if you wish the behaviour | |
123 | to be different (such as keeping a user-defined | |
124 | background colour). If you do override this function, call wxEvent::Skip to | |
125 | propagate the notification to child windows and controls. | |

133 | ||

143 | \membersection{wxPanel::SetFocus}\label{wxpanelsetfocus} | |
144 | ||
145 | \func{virtual void}{SetFocus}{\void} | |
146 | ||
147 | Overrides \helpref{wxWindow::SetFocus}{wxwindowsetfocus}. This method | |
148 | uses the (undocumented) mix-in class wxControlContainer which manages | |
149 | the focus and TAB logic for controls which usually have child controls. | |
150 | In practice, if you call this method and the control has at least | |
151 | one child window, the focus will be given to the child window. | |

160 | ||
161 | \func{virtual void}{SetFocusIgnoringChildren}{\void} | |
162 | ||
163 | In contrast to \helpref{wxPanel::SetFocus}{wxpanelsetfocus} (see above) | |
164 | this will set the focus to the panel even of there are child windows | |
165 | in the panel. This is only rarely needed. | |
