2
3 wxWindow is the base class for all windows. Any children of the window will be deleted
4 automatically by the destructor before the window itself is deleted.
5
6 %Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7 %help text. These must not be called by a user program and are documented only for illustration.
8 %On several platforms, only a few of these handlers are actually written (they are not always
9 %needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10 %the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
11 %platform can implement its native behaviour or just ignore the event if nothing needs to be
12 %done.

25 The following styles can apply to all windows, although they will not always make sense for a particular
26 window class or on all platforms.

28 \twocolwidtha{5cm}%
29 \begin{twocollist}\itemsep=0pt
30 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
31 for this style. }
32 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows only.}
33 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
34 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border. GTK only. }
35 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
36 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
37 events. Windows only.}
38 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
39 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that the window
40 wants to get all char events - even for keys like TAB or ENTER which are
41 usually used for dialog navigation and which wouldn't be generated without
42 this style}
43 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
44 the window completely when its size is changed - you will have to repaint the
45 new window area manually if you use this style. Currently only has an effect for
46 Windows.}
47 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
48 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
49 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
50 disable them instead of hiding them when they are not needed (i.e. when the
51 size of the window is big enough to not require the scrollbars to navigate it).
52 This style is currently only implemented for wxMSW and wxUniversal and does
53 nothing on the other platforms.}
54 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
55 repainted, then children being painted over them. Windows only.}

63
64 \twocolwidtha{5cm}%
65 \begin{twocollist}\itemsep=0pt
66 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
67 only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
68 descend into all subwindows.}
69 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
70 parent window and so on recursively by default. Using this flag for the
71 given window allows to block this propagation at this window, i.e. prevent
72 the events from being propagated further upwards. Dialogs have this
73 flag on by default.}
74 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
75 be used with transient windows as otherwise there is the risk of creating a
76 dialog/frame with this window as a parent which would lead to a crash if the
77 parent is destroyed before the child.}
78 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
79 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
80 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
81 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

96 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
97 \param{const wxPoint\& }{pos = wxDefaultPosition},
98 \param{const wxSize\& }{size = wxDefaultSize},
99 \param{long }{style = 0},

101
102 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
103
104 \wxheading{Parameters}
105
106 \docparam{parent}{Pointer to a parent window.}
107
108 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
109
110 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
111 should generate a default position for the window. If using the wxWindow class directly, supply
112 an actual position.}
113
114 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
115 should generate a default size for the window. If no suitable size can be found, the
116 window will be sized to 20x20 pixels so that the window is visible but obviously not
117 correctly sized. }
118
119 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
120
121 \docparam{name}{Window name.}
122
123 \membersection{wxWindow::\destruct{wxWindow}}
124
125 \func{}{\destruct{wxWindow}}{\void}
126
127 Destructor. Deletes all subwindows, then deletes itself. Instead of using
128 the {\bf delete} operator explicitly, you should normally
129 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
130 can delete a window only when it is safe to do so, in idle time.

137
138 \membersection{wxWindow::AddChild}
139
140 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
141
142 Adds a child window. This is called automatically by window creation
143 functions so should not be required by the application programmer.
144
145 Notice that this function is mostly internal to wxWindows and shouldn't be
146 called by the user code.
147
148 \wxheading{Parameters}
149
150 \docparam{child}{Child window to add.}
151
152 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
153
154 \func{virtual void}{CaptureMouse}{\void}
155
156 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
157 release the capture.
158
159 Note that wxWindows maintains the stack of windows having captured the mouse
160 and when the mouse is released the capture returns to the window which had had
161 captured it previously and it is only really released if there were no previous
162 window. In particular, this means that you must release the mouse as many times
163 as you capture it.

186
187 \membersection{wxWindow::Centre}\label{wxwindowcentre}
188
189 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
190
191 Centres the window.
192
193 \wxheading{Parameters}
194
195 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
196 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
197 if you want to center the window on the entire screen and not on its
198 parent window.}
199
200 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
201 (it has no effect).
202
203 \wxheading{Remarks}
204
205 If the window is a top level one (i.e. doesn't have a parent), it will be
206 centered relative to the screen anyhow.

214 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
215
216 Centres the window on its parent. This is a more readable synonym for
217 \helpref{Centre}{wxwindowcentre}.
218
219 \wxheading{Parameters}
220
221 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
222 or {\tt wxBOTH}.}
223
224 \wxheading{Remarks}
225
226 This methods provides for a way to center top level windows over their
227 parents instead of the entire screen. If there is no parent or if the
228 window is not a top level window, then behaviour is the same as
229 \helpref{wxWindow::Centre}{wxwindowcentre}.

236
237 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
238
239 Centres the window on screen. This only works for top level windows -
240 otherwise, the window will still be centered on its parent.
241
242 \wxheading{Parameters}
243
244 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

284
285 \membersection{wxWindow::Close}\label{wxwindowclose}
286
287 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
288
289 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
290 handler usually tries to close the window. It doesn't close the window itself,
291 however.
292
293 \wxheading{Parameters}
294
295 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
296 of this window, {\tt true} if it cannot.}
297
298 \wxheading{Remarks}
299
300 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
301 an opportunity for the window to choose whether to destroy the window.
302 Usually it is only used with the top level windows (wxFrame and wxDialog
303 classes) as the others are not supposed to have any special OnClose() logic.
304
305 The close handler should check whether the window is being deleted forcibly,
306 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
307 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
308
309 {\it Note} that calling Close does not guarantee that the window will be
310 destroyed; but it provides a way to simulate a manual close of a window, which
311 may or may not be implemented by destroying the window. The default
312 implementation of wxDialog::OnCloseWindow does not necessarily delete the
313 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
314 the appropriate button event handler and may do anything at all.
315
316 To guarantee that the window will be destroyed, call
317 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

326
327 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
328
329 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
330
331 Converts a point or size from dialog units to pixels.
332
333 For the x dimension, the dialog units are multiplied by the average character width
334 and then divided by 4.
335
336 For the y dimension, the dialog units are multiplied by the average character height
337 and then divided by 8.
338
339 \wxheading{Remarks}
340
341 Dialog units are used for maintaining a dialog's proportions even if the font changes.
342 Dialogs created using Dialog Editor optionally use dialog units.
343
344 You can also use these functions programmatically. A convenience macro is defined:
345
346 {\small
347 \begin{verbatim}
348 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

409 Destroys the window safely. Use this function instead of the delete operator, since
410 different window classes can be destroyed differently. Frames and dialogs
411 are not destroyed immediately when this function is called -- they are added
412 to a list of windows to be deleted on idle time, when all the window's events
413 have been processed. This prevents problems with events being sent to non-existent
414 windows.
415

442 Does the window-specific updating after processing the update event.
443 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
444 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and

548 \func{static wxWindow*}{FindWindowByName}{\param{const wxString\&}{ name}, \param{wxWindow*}{ parent = NULL}}
549
550 Find a window by its name (as given in a window constructor or {\bf Create} function call).
551 If {\it parent} is NULL, the search will start from all top-level
552 frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy.
553 The search is recursive in both cases.
554
555 If no window with such name is found,
556 \helpref{FindWindowByLabel}{wxwindowfindwindowbylabel} is called.

567 or panel item label. If {\it parent} is NULL, the search will start from all top-level

575 \membersection{wxWindow::Fit}\label{wxwindowfit}
576
577 \func{virtual void}{Fit}{\void}
578
579 Sizes the window so that it fits around its subwindows. This function won't do
580 anything if there are no subwindows and will only really work correctly if the
581 sizers are used for the subwindows layout. Also, if the window has exactly one
582 subwindow it is better (faster and the result is more precise as Fit adds some
583 margin to account for fuzziness of its calculations) to call
584
585 \begin{verbatim}
586 window->SetClientSize(child->GetSize());
587 \end{verbatim}
588
589 instead of calling Fit.
590
591 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}
592
593 \func{virtual void}{FitInside}{\void}
594
595 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
596 of a window. Mainly useful with scrolled windows to reset scrollbars after
597 sizing changes that do not trigger a size event, and/or scrolled windows without
598 an interior sizer. This function similarly won't do anything if there are no
599 subwindows.

603 \func{virtual void}{Freeze}{\void}
604
605 Freezes the window or, in other words, prevents any updates from taking place
606 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
607 be called to reenable window redrawing.
608
609 This method is useful for visual appearance optimization (for example, it
610 is a good idea to use it before inserting large amount of text into a
611 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
612 controls so it is mostly just a hint to wxWindows and not a mandatory

627 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
628 in one thing. GetBestSize should return the minimum untruncated size of the
629 window, while this method will return the largest of BestSize and any user
630 specified minimum size. ie. it is the minimum size the window should currently

650 example, for a static control, it will be the minimal size such that the
651 control label is not truncated. For windows containing subwindows (typically
652 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the

1825
1826 \docparam{handler}{Specifies the handler to be pushed.}
1827
1828 \wxheading{Remarks}
1829
1830 An event handler is an object that is capable of processing the events
1831 sent to a window. By default, the window is its own event handler, but
1832 an application may wish to substitute another, for example to allow
1833 central implementation of event-handling for a variety of different
1834 window classes.
1835
1836 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1837 an application to set up a chain of event handlers, where an event not handled by one event handler is
1838 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1839 remove the event handler.

2118 under Windows and automatically under GTK.
2119
2120 Note that setting the background colour does not cause an immediate refresh, so you

2122 calling this function.
2123
2124 Use this function with care under GTK+ as the new appearance of the window might
2125 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2126 look as the user wishes with run-time loadable modules.

2148
2149 This sets the size of the window client area in pixels. Using this function to size a window
2150 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2151 worry about what dimensions the border or title bar have when trying to fit the window

2184 Sets the window's cursor. Notice that the window cursor also sets it for the
2185 children of the window implicitly.
2186
2187 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will

2201
2202 Sets the window to have the given layout constraints. The window
2203 will then own the object, and will take care of its deletion.
2204 If an existing layout constraints object is already owned by the
2205 window, it will be deleted.
2206
2207 \wxheading{Parameters}
2208
2209 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2210 constraints.}
2211
2212 \wxheading{Remarks}
2213
2214 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2215 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2216 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2239
2240 \docparam{handler}{Specifies the handler to be set.}
2241
2242 \wxheading{Remarks}
2243
2244 An event handler is an object that is capable of processing the events
2245 sent to a window. By default, the window is its own event handler, but
2246 an application may wish to substitute another, for example to allow
2247 central implementation of event-handling for a variety of different
2248 window classes.
2249
2250 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2251 this sets up a chain of event handlers, where an event not handled by one event handler is
2252 handed to the next one in the chain.

2274 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2275 events are propagated upwards to the window parent recursively until a handler
2276 for them is found. Using this style allows to prevent them from being
2277 propagated beyond this window. Notice that wxDialog has this style on by
2278 default for the reasons explained in the
2279 \helpref{event processing overview}{eventprocessing}.}
2280 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2281 window from being used as an implicit parent for the dialogs which were

2287 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2288 you should use the style of
2289 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2425 Let's say you wish to display 50 lines of text, using the same font.
2426 The window is sized so that you can only see 16 lines at a time.
2427
2428 You would use:
2429
2430 {\small%
2431 \begin{verbatim}
2432 SetScrollbar(wxVERTICAL, 0, 16, 50);
2433 \end{verbatim}
2434 }
2435
2436 Note that with the window at this size, the thumb position can never go
2437 above 50 minus 16, or 34.
2438
2439 You can determine how many lines are currently visible by dividing the current view
2440 size by the character height in pixels.
2441
2442 When defining your own scrollbar behaviour, you will always need to recalculate
2443 the scrollbar settings when the window size changes. You could therefore put your
2444 scrollbar calculations and SetScrollbar
2445 call into a function named AdjustScrollbars, which can be called initially and also
2446 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2467
2468 \wxheading{Remarks}
2469
2470 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2471 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2472 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2473 value has to be adjusted when the window is resized, since the page size will have changed.
2474
2475 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2476 the thumb changes size to reflect the page size relative to the length of the document. When the
2477 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2478 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2479 disappear.
2480
2481 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2482 handling of pages and ranges.

2534
2535 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2536 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2537 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2538 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2539 and usually the scrollbar will be automatically hidden.

2640
2641 \wxheading{Remarks}
2642
2643 If this function is called, the user will not be able to size the window outside the
2644 given bounds.
2645
2646 The resizing increments are only significant under Motif or Xt.
2647
2648 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
2649
2650 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2651
2652 Sets the window to have the given layout sizer. The window
2653 will then own the object, and will take care of its deletion.
2654 If an existing layout constraints object is already owned by the
2655 window, it will be deleted if the deleteOld parameter is true.
2656
2657 Note that this function will also call
2658 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
2659 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
2660
2661 \wxheading{Parameters}
2662
2663 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
2664 the window's sizer. See below.}
2665
2666 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
2667 Pass false if you wish to handle deleting the old sizer yourself.}
2668
2669 \wxheading{Remarks}
2670
2671 SetSizer now enables and disables Layout automatically, but prior to wxWindows 2.3.3
2672 the following applied:
2673
2674 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2675 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2676 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2677 only the sizer will have effect.
2678

2680
2681 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2682
2683 The same as \helpref{SetSizer}{wxwindowsetsizer}, except it also sets the size hints
2684 for the window based on the sizer's minimum size.
2685
2686 \membersection{wxWindow::SetTitle}\label{wxwindowsettitle}

2700 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
2701
2702 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
2703
2704 This function tells a window if it should use the system's "theme" code
2705 to draw the windows' background instead if its own background drawing
2706 code. This does not always have any effect since the underlying platform
2707 obviously needs to support the notion of themes in user defined windows.
2708 One such platform is GTK+ where windows can have (very colourful) backgrounds
2709 defined by a user's selected theme.
2710
2711 Dialogs, notebook pages and the status bar have this flag set to true
2712 by default so that the default look and feel is simulated best.

2742 \func{virtual void}{SetVirtualSizeHints}{\param{int}{ minW},\param{int}{ minH}, \param{int}{ maxW=-1}, \param{int}{ maxH=-1}}
2743
2744 Allows specification of minimum and maximum virtual window sizes.
2745 If a pair of values is not set (or set to -1), the default values
2746 will be used.
2747

2772
2773 Sets the style of the window. Please note that some styles cannot be changed
2774 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2775 be called after changing the others for the change to take place immediately.

2784
2785 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2786
2787 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2788 for a top level window if you want to bring it to top, although this is not
2789 needed if Show() is called immediately after the frame creation.
2790

2792
2793 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2794
2795 \wxheading{Return value}
2796

2866 \membersection{wxWindow::Update}\label{wxwindowupdate}
2867
2868 \func{virtual void}{Update}{\void}
2869
2870 Calling this method immediately repaints the invalidated area of the window
2871 while this would usually only happen when the flow of control returns to the
2872 event loop. Notice that this function doesn't refresh the window and does
2873 nothing if the window hadn't been already repainted. Use
2874 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2875 window unconditionally.
2876
2877 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
2878
2879 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
2880
2881 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
2882 the window. The particular implementation depends on the window; for
2883 example a wxToolBar will send an update UI event for each toolbar button,
2884 and a wxFrame will send an update UI event for each menubar menu item.
2885 You can call this function from your application to ensure that your
2886 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2887 are concerned). This may be necessary if you have called
2888 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
2889 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
2890 limit the overhead that wxWindows incurs by sending update UI events in idle time.
2891
2892 {\it flags} should be a bitlist of one or more of the following values.
2893
2894 \begin{verbatim}
2895 enum wxUpdateUI
2896 {
2897 wxUPDATE_UI_NONE = 0x0000, // No particular value
2898 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
2899 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
2900 };
2901 \end{verbatim}
2902
2903 If you are calling this function from an OnInternalIdle or OnIdle
2904 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
2905 this tells the window to only update the UI elements that need
2906 to be updated in idle time. Some windows update their elements
2907 only when necessary, for example when a menu is about to be shown.
2908 The following is an example of how to call UpdateWindowUI from
2909 an idle function.
2910
2911 \begin{verbatim}
2912 void MyWindow::OnInternalIdle()
2913 {
2914 if (wxUpdateUIEvent::CanUpdate(this))
2915 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
2916 }
