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

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

166 The width of the status bar is the whole width of the frame (adjusted automatically when
167 resizing), and the height and text size are chosen by the host windowing system.
168
169 By default, the status bar is an instance of wxStatusBar. To use a different class,
170 override \helpref{wxFrame::OnCreateStatusBar}{wxframeoncreatestatusbar}.

198
199 A pointer to the the toolbar if it was created successfully, NULL otherwise.
200
201 \wxheading{Remarks}
202
203 By default, the toolbar is an instance of wxToolBar (which is defined to be
204 a suitable toolbar class on each platform, such as wxToolBar95). To use a different class,
205 override \helpref{wxFrame::OnCreateToolBar}{wxframeoncreatetoolbar}.
206
207 When a toolbar has been created with this function, or made known to the frame
208 with \helpref{wxFrame::SetToolBar}{wxframesettoolbar}, the frame will manage the toolbar
209 position and adjust the return value from \helpref{wxWindow::GetClientSize}{wxwindowgetclientsize} to
210 reflect the available space for application windows.

394 See \helpref{wxWindow::OnSize}{wxwindowonsize}.
395
396 The default {\bf wxFrame::OnSize} implementation looks for a single subwindow,
397 and if one is found, resizes it to fit
398 inside the frame. Override this member if more complex behaviour
399 is required (for example, if there are several subwindows).
400
401 \membersection{wxFrame::SetIcon}\label{wxframeseticon}
402
403 \func{void}{SetIcon}{\param{const wxIcon\& }{icon}}
404
405 Sets the icon for this frame.
406
407 \wxheading{Parameters}
408
409 \docparam{icon}{The icon to associate with this frame.}
410
411 \wxheading{Remarks}
412
413 The frame takes a `copy' of {\it icon}, but since it uses reference
414 counting, the copy is very quick. It is safe to delete {\it icon} after
415 calling this function.
416
417 Under Windows, instead of using {\bf SetIcon}, you can add the
418 following lines to your MS Windows resource file:
419
420 \begin{verbatim}
421 wxSTD_MDIPARENTFRAME ICON icon1.ico
422 wxSTD_MDICHILDFRAME ICON icon2.ico
423 wxSTD_FRAME ICON icon3.ico
424 \end{verbatim}
425
426 where icon1.ico will be used for the MDI parent frame, icon2.ico
427 will be used for MDI child frames, and icon3.ico will be used for
428 non-MDI frames.
429
430 If these icons are not supplied, and {\bf SetIcon} is not called either,
431 then the following defaults apply if you have included wx.rc.
432
433 \begin{verbatim}
434 wxDEFAULT_FRAME ICON std.ico
435 wxDEFAULT_MDIPARENTFRAME ICON mdi.ico
436 wxDEFAULT_MDICHILDFRAME ICON child.ico
437 \end{verbatim}
438
439 You can replace std.ico, mdi.ico and child.ico with your own defaults
440 for all your wxWindows application. Currently they show the same icon.
441
442 {\it Note:} a wxWindows application linked with subsystem equal to 4.0
443 (i.e. marked as a Windows 95 application) doesn't respond properly
444 to wxFrame::SetIcon. To work around this until a solution is found,
445 mark your program as a 3.5 application. This will also ensure
446 that Windows provides small icons for the application automatically.
447
448 See also \helpref{wxIcon}{wxicon}.
449
450 \membersection{wxFrame::SetMenuBar}\label{wxframesetmenubar}
451
452 \func{void}{SetMenuBar}{\param{wxMenuBar* }{menuBar}}
453
454 Tells the frame to show the given menu bar.
455
456 \wxheading{Parameters}
457
458 \docparam{menuBar}{The menu bar to associate with the frame.}
459
460 \wxheading{Remarks}
461
462 If the frame is destroyed, the
463 menu bar and its menus will be destroyed also, so do not delete the menu
464 bar explicitly (except by resetting the frame's menu bar to another
465 frame or NULL).
466
467 Under Windows, a call to \helpref{wxFrame::OnSize}{wxframeonsize} is generated, so be sure to initialize
468 data members properly before calling {\bf SetMenuBar}.
469
470 Note that it is not possible to call this function twice for the same frame object.

512
513 \wxheading{Parameters}
514
515 \wxheading{n}{The number of fields in the status bar. It must be the
516 same used in \helpref{CreateStatusBar}{wxframecreatestatusbar}.}
517
518 \docparam{widths}{Must contain an array of {\it n} integers, each of which is a status field width
519 in pixels. A value of -1 indicates that the field is variable width; at least one
520 field must be -1. You should delete this array after calling {\bf SetStatusWidths}.}
521
522 \wxheading{Remarks}
523
524 The widths of the variable fields are calculated from the total width of all fields,
525 minus the sum of widths of the non-variable fields, divided by the number of
526 variable fields.
