2
3 A frame is a window whose size and position can (usually) be changed by the user. It usually has
4 thick borders and a title bar, and can optionally contain a menu bar, toolbar and
5 status bar. A frame can contain any window that is not a frame or dialog.
6
7 A frame that has a status bar and toolbar created via the CreateStatusBar/CreateToolBar functions
8 manages these windows, and adjusts the value returned by GetClientSize to reflect
9 the remaining size available to application windows.

38 An application should normally define an \helpref{OnCloseWindow}{wxwindowonclosewindow} handler for the
39 frame to respond to system close events, for example so that related data and subwindows can be cleaned up.

150 A pointer to the the status bar if it was created successfully, NULL otherwise.
151
152 \wxheading{Remarks}
153
154 The width of the status bar is the whole width of the frame (adjusted automatically when
155 resizing), and the height and text size are chosen by the host windowing system.
156
157 By default, the status bar is an instance of wxStatusBar. To use a different class,
158 override \helpref{wxFrame::OnCreateStatusBar}{wxframeoncreatestatusbar}.
159
160 Note that you can put controls and other windows on the status bar if you wish.

174
175 \wxheading{Parameters}
176
177 \docparam{style}{The toolbar style. See \helpref{wxToolBar}{wxtoolbar} for a list
178 of valid styles.}

186
187 A pointer to the the toolbar if it was created successfully, NULL otherwise.
188
189 \wxheading{Remarks}
190
191 By default, the toolbar is an instance of wxToolBar (which is defined to be
192 a suitable toolbar class on each platform, such as wxToolBar95). To use a different class,
193 override \helpref{wxFrame::OnCreateToolBar}{wxframeoncreatetoolbar}.
194
195 When a toolbar has been created with this function, or made known to the frame
196 with \helpref{wxFrame::SetToolBar}{wxframesettoolbar}, the frame will manage the toolbar
197 position and adjust the return value from \helpref{wxWindow::GetClientSize}{wxwindowgetclientsize} to
198 reflect the available space for application windows.

263 Returns TRUE if the frame is iconized.
264
265 \membersection{wxFrame::LoadAccelerators}\label{wxframeloadaccelerators}
266
267 \func{void}{LoadAccelerators}{\param{const wxString\& }{table}}
268

270
271 \wxheading{Parameters}
272
273 \docparam{table}{Accelerator table to load.}
274
275 \wxheading{Return value}
276
277 TRUE if the operation was successful, FALSE otherwise.
278
279 \wxheading{Remarks}
280
281 Accelerator tables map keystrokes onto control and menu identifiers, so the
282 programmer does not have to explicitly program this correspondence.
283
284 See the hello demo ({\tt hello.cpp} and {\tt hello.rc}) for
285 an example of accelerator usage. This is a fragment from {\tt hello.rc}:
286
287 \begin{verbatim}
288 #define HELLO_LOAD_FILE 111
289
290 menus_accel ACCELERATORS
291 {
292
293 "^L", HELLO_LOAD_FILE
294
295 }
296 \end{verbatim}
297
298 This function only works under Windows.
299
300 % huh? If you call LoadAccelerators, you need to override wxFrame::OnActivate to do nothing.
301
302 \membersection{wxFrame::Maximize}\label{wxframemaximize}
303
304 \func{void}{Maximize}{\param{const bool }{maximize}}
305
306 Maximizes or restores the frame.
307
308 \wxheading{Parameters}
309
310 \docparam{maximize}{If TRUE, maximizes the frame, otherwise it restores it}.
311
312 \wxheading{Remarks}
313

319
320 \membersection{wxFrame::OnActivate}
321
322 \func{void}{OnActivate}{\param{bool}{ active}}
323
324 Called when a window is activated or deactivated (MS Windows
325 only). If the window is being activated, {\it active} is TRUE, else it
326 is FALSE.
327
328 If you call wxFrame::LoadAccelerators, you need to override this function e.g.
329
330 \begin{verbatim}
331 void OnActivate(bool) {};
332 \end{verbatim}
333
334 \membersection{wxFrame::OnCreateStatusBar}\label{wxframeoncreatestatusbar}
335
336 \func{virtual wxStatusBar*}{OnCreateStatusBar}{\param{int }{number}
337 \param{long}{ style},
338 \param{wxWindowID}{ id}, \param{const wxString\&}{ name}}
339
340 Virtual function called when a status bar is requested by \helpref{wxFrame::CreateStatusBar}{wxframecreatestatusbar}.
341
342 \wxheading{Parameters}
343
344 \docparam{number}{The number of fields to create.}
345
346 \docparam{style}{The window style. See \helpref{wxStatusBar}{wxstatusbar} for a list
347 of valid styles.}
348
349 \docparam{id}{The window identifier. If -1, an identifier will be chosen by
350 wxWindows.}
351
352 \docparam{name}{The window name.}
353
354 \wxheading{Return value}
355
356 A status bar object.
357
358 \wxheading{Remarks}
359
360 An application can override this function to return a different kind of status bar. The default
361 implementation returns an instance of \helpref{wxStatusBar}{wxstatusbar}.

371
372 Virtual function called when a toolbar is requested by \helpref{wxFrame::CreateToolBar}{wxframecreatetoolbar}.
373
374 \wxheading{Parameters}
375
376 \docparam{style}{The toolbar style. See \helpref{wxToolBar}{wxtoolbar} for a list

380 wxWindows.}
381
382 \docparam{name}{The toolbar window name.}
383
384 \wxheading{Return value}
385
386 A toolbar object.
387
388 \wxheading{Remarks}
389
390 An application can override this function to return a different kind of toolbar. The default
391 implementation returns an instance of \helpref{wxToolBar}{wxtoolbar}.

410
411 \func{void}{OnSize}{\param{wxSizeEvent\& }{event}}
412
413 See \helpref{wxWindow::OnSize}{wxwindowonsize}.
414
415 The default {\bf wxFrame::OnSize} implementation looks for a single subwindow,
416 and if one is found, resizes it to fit
417 inside the frame. Override this member if more complex behaviour
418 is required (for example, if there are several subwindows).
419
420 \membersection{wxFrame::SetIcon}\label{wxframeseticon}
421
422 \func{void}{SetIcon}{\param{const wxIcon\& }{icon}}
423
424 Sets the icon for this frame.
425
426 \wxheading{Parameters}
427
428 \docparam{icon}{The icon to associate with this frame.}
429
430 \wxheading{Remarks}
431
432 The frame takes a `copy' of {\it icon}, but since it uses reference
433 counting, the copy is very quick. It is safe to delete {\it icon} after
434 calling this function.
435
436 Under Windows, instead of using {\bf SetIcon}, you can add the
437 following lines to your MS Windows resource file:
438
439 \begin{verbatim}
440 wxSTD_MDIPARENTFRAME ICON icon1.ico
441 wxSTD_MDICHILDFRAME ICON icon2.ico
442 wxSTD_FRAME ICON icon3.ico
443 \end{verbatim}
444
445 where icon1.ico will be used for the MDI parent frame, icon2.ico
446 will be used for MDI child frames, and icon3.ico will be used for
447 non-MDI frames.
448
449 If these icons are not supplied, and {\bf SetIcon} is not called either,
450 then the following defaults apply if you have included wx.rc.
451
452 \begin{verbatim}
453 wxDEFAULT_FRAME ICON std.ico
454 wxDEFAULT_MDIPARENTFRAME ICON mdi.ico
455 wxDEFAULT_MDICHILDFRAME ICON child.ico
456 \end{verbatim}
457
458 You can replace std.ico, mdi.ico and child.ico with your own defaults
459 for all your wxWindows application. Currently they show the same icon.
460
461 {\it Note:} a wxWindows application linked with subsystem equal to 4.0
462 (i.e. marked as a Windows 95 application) doesn't respond properly
463 to wxFrame::SetIcon. To work around this until a solution is found,
464 mark your program as a 3.5 application. This will also ensure
465 that Windows provides small icons for the application automatically.
466
467 See also \helpref{wxIcon}{wxicon}.
468
469 \membersection{wxFrame::SetMenuBar}\label{wxframesetmenubar}
470
471 \func{void}{SetMenuBar}{\param{wxMenuBar* }{menuBar}}
472
473 Tells the frame to show the given menu bar.
474
475 \wxheading{Parameters}
476
477 \docparam{menuBar}{The menu bar to associate with the frame.}
478
479 \wxheading{Remarks}
480
481 If the frame is destroyed, the
482 menu bar and its menus will be destroyed also, so do not delete the menu
483 bar explicitly (except by resetting the frame's menu bar to another
484 frame or NULL).
485
486 Under Windows, a call to \helpref{wxFrame::OnSize}{wxframeonsize} is generated, so be sure to initialize
487 data members properly before calling {\bf SetMenuBar}.
488
489 Note that it is not possible to call this function twice for the same frame object.

530 Sets the widths of the fields in the status bar.
531
532 \wxheading{Parameters}
533
534 \wxheading{n}{The number of fields in the status bar. It must be the
535 same used in \helpref{CreateStatusBar}{wxframecreatestatusbar}.}
536
537 \docparam{widths}{Must contain an array of {\it n} integers, each of which is a status field width
538 in pixels. A value of -1 indicates that the field is variable width; at least one
539 field must be -1. You should delete this array after calling {\bf SetStatusWidths}.}
540
541 \wxheading{Remarks}
542
