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.

42 \twocolitem{\windowstyle{wxFRAME\_NO\_TASKBAR}}{Creates an otherwise normal
43 frame but it does not appear in the taskbar under Windows or GTK+ (note that it
44 will minimize to the desktop window under Windows which may seem strange to the
45 users and thus it might be better to use this style only without
46 wxMINIMIZE\_BOX style). In wxGTK, the flag is respected only if GTK+ is at
47 least version 2.2 and the window manager supports
48 \urlref{\_NET\_WM\_STATE\_SKIP\_TASKBAR}{http://freedesktop.org/Standards/wm-spec/1.3/ar01s05.html} hint.
49 Has no effect under other platforms.}
50 \twocolitem{\windowstyle{wxFRAME\_FLOAT\_ON\_PARENT}}{The frame will always be
51 on top of its parent (unlike wxSTAY\_ON\_TOP). A frame created with this style
52 must have a non-NULL parent.}
53 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
54 caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send
55 a wxEVT\_HELP event if the user clicked on an application window. {\it Note} that this is an extended
56 style and must be set by calling \helpref{SetExtraStyle}{wxwindowsetextrastyle} before Create is called (two-step construction).
57 You cannot use this style together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
58 you should use\rtfsp
59 {\tt wxDEFAULT\_FRAME\_STYLE \& ~ (wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
60 frames having this style (the dialogs don't have a minimize or a maximize box by
61 default)}

63 allowed to have their shape changed with the \helpref{SetShape}{wxtoplevelwindowsetshape} method.}
64 \end{twocollist}
65
66 The default frame style is for normal, resizeable frames. To create a frame
67 which can not be resized by user, you may use the following combination of
68 styles: {\tt wxDEFAULT\_FRAME\_STYLE \& ~ (wxRESIZE\_BORDER \pipe wxRESIZE\_BOX \pipe wxMAXIMIZE\_BOX)}.
69 % Note: the space after the tilde is necessary or Tex2RTF complains.

73 \wxheading{Default event processing}
74
75 wxFrame processes the following events:
76
77 \begin{twocollist}\itemsep=0pt
78 \twocolitem{\helpref{wxEVT\_SIZE}{wxsizeevent}}{If the frame has exactly one
79 child window, not counting the status and toolbar, this child is resized to
80 take the entire frame client area. If two or more windows are present, they
81 should be laid out explicitly either by manually handling wxEVT\_SIZE or using
82 \helpref{sizers}{sizeroverview}}
83
84 \twocolitem{\helpref{wxEVT\_MENU\_HIGHLIGHT}{wxmenuevent}}{The default
85 implementation displays the \helpref{help string}{wxmenuitemgethelp} associated
86 with the selected item in the first pane of the status bar, if there is one.}
87 \end{twocollist}
88
89 \wxheading{Remarks}
90
91 An application should normally define an \helpref{wxCloseEvent}{wxcloseevent} handler for the
92 frame to respond to system close events, for example so that related data and subwindows can be cleaned up.

207 The width of the status bar is the whole width of the frame (adjusted automatically when
208 resizing), and the height and text size are chosen by the host windowing system.
209
210 By default, the status bar is an instance of wxStatusBar. To use a different class,
211 override \helpref{wxFrame::OnCreateStatusBar}{wxframeoncreatestatusbar}.
212
213 Note that you can put controls and other windows on the status bar if you wish.

225
226 Creates a toolbar at the top or left of the frame.
227
228 \wxheading{Parameters}
229
230 \docparam{style}{The toolbar style. See \helpref{wxToolBar}{wxtoolbar} for a list
231 of valid styles.}
232

236 \docparam{name}{The toolbar window name.}
237
238 \wxheading{Return value}
239
240 A pointer to the the toolbar if it was created successfully, NULL otherwise.
241
242 \wxheading{Remarks}
243
244 By default, the toolbar is an instance of wxToolBar (which is defined to be
245 a suitable toolbar class on each platform, such as wxToolBar95). To use a different class,
246 override \helpref{wxFrame::OnCreateToolBar}{wxframeoncreatetoolbar}.
247
248 When a toolbar has been created with this function, or made known to the frame
249 with \helpref{wxFrame::SetToolBar}{wxframesettoolbar}, the frame will manage the toolbar
250 position and adjust the return value from \helpref{wxWindow::GetClientSize}{wxwindowgetclientsize} to
251 reflect the available space for application windows.

371 \membersection{wxFrame::SendSizeEvent}\label{wxframesendsizeevent}
372
373 \func{void}{SendSizeEvent}{\void}
374
375 This function sends a dummy \helpref{size event}{wxsizeevent} to the frame
376 forcing it to reevaluate its children positions. It is sometimes useful to call
377 this function after adding or deleting a children after the frame creation or
378 if a child size changes.
379
380 Note that if the frame is using either sizers or constraints for the children
381 layout, it is enough to call \helpref{Layout()}{wxwindowlayout} directly and
382 this function should not be used in this case.
383
384 % VZ: we don't have all this any more (18.08.00)
385 %
386 %Under Windows, instead of using {\bf SetIcon}, you can add the
387 %following lines to your MS Windows resource file:
388 %
389 %\begin{verbatim}
390 %wxSTD_MDIPARENTFRAME ICON icon1.ico
391 %wxSTD_MDICHILDFRAME ICON icon2.ico
392 %wxSTD_FRAME ICON icon3.ico
393 %\end{verbatim}
394 %
395 %where icon1.ico will be used for the MDI parent frame, icon2.ico
396 %will be used for MDI child frames, and icon3.ico will be used for
397 %non-MDI frames.
398 %
399 %If these icons are not supplied, and {\bf SetIcon} is not called either,
400 %then the following defaults apply if you have included wx.rc.
401 %
402 %\begin{verbatim}
403 %wxDEFAULT_FRAME ICON std.ico
404 %wxDEFAULT_MDIPARENTFRAME ICON mdi.ico
405 %wxDEFAULT_MDICHILDFRAME ICON child.ico
406 %\end{verbatim}

408 %You can replace std.ico, mdi.ico and child.ico with your own defaults

416
417 \wxheading{Parameters}
418
419 \docparam{menuBar}{The menu bar to associate with the frame.}
420
421 \wxheading{Remarks}
422
423 If the frame is destroyed, the
424 menu bar and its menus will be destroyed also, so do not delete the menu
425 bar explicitly (except by resetting the frame's menu bar to another
426 frame or NULL).
427
428 Under Windows, a size event is generated, so be sure to initialize
429 data members properly before calling {\bf SetMenuBar}.
430
431 Note that on some platforms, it is not possible to call this function twice for the same frame object.

489
490 \wxheading{Remarks}
491
