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.

24
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.
27
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.}
56 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
57 a complete redraw of the window whenever it is resized instead of redrawing
58 just the part of the window affected by resizing. Note that this was the
59 behaviour by default before 2.5.1 release and that if you experience redraw
60 problems with the code which previously used to work you may want to try this.}

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

106
107 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
108
109 \wxheading{Parameters}
110
111 \docparam{parent}{Pointer to a parent window.}
112
113 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
114
115 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
116 should generate a default position for the window. If using the wxWindow class directly, supply
117 an actual position.}
118
119 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
120 should generate a default size for the window. If no suitable size can be found, the
121 window will be sized to 20x20 pixels so that the window is visible but obviously not
122 correctly sized. }
123
124 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
125
126 \docparam{name}{Window name.}
127
128 \membersection{wxWindow::\destruct{wxWindow}}
129
130 \func{}{\destruct{wxWindow}}{\void}
131
132 Destructor. Deletes all subwindows, then deletes itself. Instead of using
133 the {\bf delete} operator explicitly, you should normally
134 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
135 can delete a window only when it is safe to do so, in idle time.

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

191
192 \membersection{wxWindow::Centre}\label{wxwindowcentre}
193
194 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
195
196 Centres the window.
197
198 \wxheading{Parameters}
199
200 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
201 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
202 if you want to center the window on the entire screen and not on its
203 parent window.}
204
205 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
206 (it has no effect).
207
208 \wxheading{Remarks}
209
210 If the window is a top level one (i.e. doesn't have a parent), it will be
211 centered relative to the screen anyhow.

220
221 Centres the window on its parent. This is a more readable synonym for
222 \helpref{Centre}{wxwindowcentre}.
223
224 \wxheading{Parameters}
225
226 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
227 or {\tt wxBOTH}.}
228
229 \wxheading{Remarks}
230
231 This methods provides for a way to center top level windows over their
232 parents instead of the entire screen. If there is no parent or if the
233 window is not a top level window, then behaviour is the same as
234 \helpref{wxWindow::Centre}{wxwindowcentre}.

241
242 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
243
244 Centres the window on screen. This only works for top level windows -
245 otherwise, the window will still be centered on its parent.
246
247 \wxheading{Parameters}
248
249 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

274 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
275 a screen coordinate will be passed out.}

288 }
289
290 \membersection{wxWindow::Close}\label{wxwindowclose}
291
292 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
293
294 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
295 handler usually tries to close the window. It doesn't close the window itself,
296 however.
297
298 \wxheading{Parameters}
299
300 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
301 of this window, {\tt true} if it cannot.}
302
303 \wxheading{Remarks}
304
305 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
306 an opportunity for the window to choose whether to destroy the window.
307 Usually it is only used with the top level windows (wxFrame and wxDialog
308 classes) as the others are not supposed to have any special OnClose() logic.
309
310 The close handler should check whether the window is being deleted forcibly,
311 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
312 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
313
314 {\it Note} that calling Close does not guarantee that the window will be
315 destroyed; but it provides a way to simulate a manual close of a window, which
316 may or may not be implemented by destroying the window. The default
317 implementation of wxDialog::OnCloseWindow does not necessarily delete the
318 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
319 the appropriate button event handler and may do anything at all.
320
321 To guarantee that the window will be destroyed, call
322 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

331
332 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
333
334 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
335
336 Converts a point or size from dialog units to pixels.
337
338 For the x dimension, the dialog units are multiplied by the average character width
339 and then divided by 4.
340
341 For the y dimension, the dialog units are multiplied by the average character height
342 and then divided by 8.
343
344 \wxheading{Remarks}
345
346 Dialog units are used for maintaining a dialog's proportions even if the font changes.
347 Dialogs created using Dialog Editor optionally use dialog units.
348
349 You can also use these functions programmatically. A convenience macro is defined:
350
351 {\small
352 \begin{verbatim}
353 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

411

413
414 Destroys the window safely. Use this function instead of the delete operator, since
415 different window classes can be destroyed differently. Frames and dialogs
416 are not destroyed immediately when this function is called -- they are added
417 to a list of windows to be deleted on idle time, when all the window's events
418 have been processed. This prevents problems with events being sent to non-existent
419 windows.
420

447 Does the window-specific updating after processing the update event.
448 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
449 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
450 act appropriately. For example, to allow frame and dialog title updating, wxWindows

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

608 \func{virtual void}{Freeze}{\void}
609
610 Freezes the window or, in other words, prevents any updates from taking place
611 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
612 be called to reenable window redrawing.
613
614 This method is useful for visual appearance optimization (for example, it
615 is a good idea to use it before inserting large amount of text into a
616 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
617 controls so it is mostly just a hint to wxWindows and not a mandatory

632 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
633 in one thing. GetBestSize should return the minimum untruncated size of the
634 window, while this method will return the largest of BestSize and any user

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

1831 \docparam{handler}{Specifies the handler to be pushed.}
1832
1833 \wxheading{Remarks}
1834
1835 An event handler is an object that is capable of processing the events
1836 sent to a window. By default, the window is its own event handler, but
1837 an application may wish to substitute another, for example to allow
1838 central implementation of event-handling for a variety of different
1839 window classes.
1840
1841 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1842 an application to set up a chain of event handlers, where an event not handled by one event handler is
1843 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1844 remove the event handler.

2130 not look equally well when used with "Themes", i.e GTK+'s ability to change its

2154 This sets the size of the window client area in pixels. Using this function to size a window
2155 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2156 worry about what dimensions the border or title bar have when trying to fit the window

2207 Sets the window to have the given layout constraints. The window
2208 will then own the object, and will take care of its deletion.
2209 If an existing layout constraints object is already owned by the
2210 window, it will be deleted.
2211
2212 \wxheading{Parameters}

2244
2245 \docparam{handler}{Specifies the handler to be set.}
2246
2247 \wxheading{Remarks}
2248
2249 An event handler is an object that is capable of processing the events
2250 sent to a window. By default, the window is its own event handler, but
2251 an application may wish to substitute another, for example to allow
2252 central implementation of event-handling for a variety of different
2253 window classes.
2254
2255 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2256 this sets up a chain of event handlers, where an event not handled by one event handler is
2257 handed to the next one in the chain.

2279 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2280 events are propagated upwards to the window parent recursively until a handler
2281 for them is found. Using this style allows to prevent them from being
2282 propagated beyond this window. Notice that wxDialog has this style on by
2283 default for the reasons explained in the
2284 \helpref{event processing overview}{eventprocessing}.}
2285 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2286 window from being used as an implicit parent for the dialogs which were
2287 created without a parent. It is useful for the windows which can disappear at

2291 a wxEVT\_HELP event if the user clicked on an application window.
2292 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2293 you should use the style of
2294 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2430 Let's say you wish to display 50 lines of text, using the same font.
2431 The window is sized so that you can only see 16 lines at a time.
2432
2433 You would use:
2434
2435 {\small%
2436 \begin{verbatim}
2437 SetScrollbar(wxVERTICAL, 0, 16, 50);
2438 \end{verbatim}
2439 }
2440
2441 Note that with the window at this size, the thumb position can never go
2442 above 50 minus 16, or 34.
2443
2444 You can determine how many lines are currently visible by dividing the current view
2445 size by the character height in pixels.
2446
2447 When defining your own scrollbar behaviour, you will always need to recalculate
2448 the scrollbar settings when the window size changes. You could therefore put your
2449 scrollbar calculations and SetScrollbar
2450 call into a function named AdjustScrollbars, which can be called initially and also
2451 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2472
2473 \wxheading{Remarks}
2474
2475 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2476 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2477 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2478 value has to be adjusted when the window is resized, since the page size will have changed.
2479
2480 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2481 the thumb changes size to reflect the page size relative to the length of the document. When the
2482 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2483 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2484 disappear.
2485
2486 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2487 handling of pages and ranges.

2539
2540 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2541 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2542 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2543 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2544 and usually the scrollbar will be automatically hidden.

2629 Allows specification of minimum and maximum window sizes, and window size increments.
2630 If a pair of values is not set (or set to -1), the default values will be used.
2631
2632 \wxheading{Parameters}
2633
2634 \docparam{minW}{Specifies the minimum width allowable.}
2635
2636 \docparam{minH}{Specifies the minimum height allowable.}
2637
2638 \docparam{maxW}{Specifies the maximum width allowable.}
2639
2640 \docparam{maxH}{Specifies the maximum height allowable.}
2641
2642 \docparam{incW}{Specifies the increment for sizing the width (Motif/Xt only).}
2643
2644 \docparam{incH}{Specifies the increment for sizing the height (Motif/Xt only).}
2645
2646 \wxheading{Remarks}
2647
2648 If this function is called, the user will not be able to size the window outside the
2649 given bounds.
2650
2651 The resizing increments are only significant under Motif or Xt.
2652
2653 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
2654
2655 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2656
2657 Sets the window to have the given layout sizer. The window
2658 will then own the object, and will take care of its deletion.
2659 If an existing layout constraints object is already owned by the
2660 window, it will be deleted if the deleteOld parameter is true.
2661
2662 Note that this function will also call
2663 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
2664 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
2665
2666 \wxheading{Parameters}
2667
2668 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
2669 the window's sizer. See below.}
2670
2671 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
2672 Pass false if you wish to handle deleting the old sizer yourself.}
2673
2674 \wxheading{Remarks}
2675
2676 SetSizer now enables and disables Layout automatically, but prior to wxWindows 2.3.3
2677 the following applied:
2678
2679 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2680 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2681 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2682 only the sizer will have effect.
2683
2684 \membersection{wxWindow::SetSizerAndFit}\label{wxwindowsetsizerandfit}
2685
2686 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2687
2688 The same as \helpref{SetSizer}{wxwindowsetsizer}, except it also sets the size hints
2689 for the window based on the sizer's minimum size.
2690
2691 \membersection{wxWindow::SetTitle}\label{wxwindowsettitle}
2692
2693 \func{virtual void}{SetTitle}{\param{const wxString\& }{title}}
2694
2695 Sets the window's title. Applicable only to frames and dialogs.
2696
2697 \wxheading{Parameters}
2698
2699 \docparam{title}{The window's title.}
2700
2701 \wxheading{See also}
2702
2703 \helpref{wxWindow::GetTitle}{wxwindowgettitle}
2704
2705 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
2706
2707 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
2708
2709 This function tells a window if it should use the system's "theme" code
2710 to draw the windows' background instead if its own background drawing
2711 code. This does not always have any effect since the underlying platform
2712 obviously needs to support the notion of themes in user defined windows.
2713 One such platform is GTK+ where windows can have (very colourful) backgrounds
2714 defined by a user's selected theme.
2715
2716 Dialogs, notebook pages and the status bar have this flag set to true
2717 by default so that the default look and feel is simulated best.
2718

2735 create a new validator of this type.
2736

2746
2747 \func{virtual void}{SetVirtualSizeHints}{\param{int}{ minW},\param{int}{ minH}, \param{int}{ maxW=-1}, \param{int}{ maxH=-1}}
2748
2749 Allows specification of minimum and maximum virtual window sizes.
2750 If a pair of values is not set (or set to -1), the default values
2751 will be used.
2752
2753 \wxheading{Parameters}
2754
2755 \docparam{minW}{Specifies the minimum width allowable.}
2756

2773
2774 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
2775
2776 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
2777
2778 Sets the style of the window. Please note that some styles cannot be changed
2779 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2780 be called after changing the others for the change to take place immediately.

2789
2790 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2791
2792 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2793 for a top level window if you want to bring it to top, although this is not
2794 needed if Show() is called immediately after the frame creation.
2795
2796 \wxheading{Parameters}
2797
2798 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2799
2800 \wxheading{Return value}
2801

2871 \membersection{wxWindow::Update}\label{wxwindowupdate}
2872
2873 \func{virtual void}{Update}{\void}
2874
2875 Calling this method immediately repaints the invalidated area of the window
2876 while this would usually only happen when the flow of control returns to the
2877 event loop. Notice that this function doesn't refresh the window and does
2878 nothing if the window hadn't been already repainted. Use
2879 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2880 window unconditionally.
2881
2882 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
2883
2884 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
2885
2886 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
2887 the window. The particular implementation depends on the window; for
2888 example a wxToolBar will send an update UI event for each toolbar button,
2889 and a wxFrame will send an update UI event for each menubar menu item.
2890 You can call this function from your application to ensure that your
2891 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2892 are concerned). This may be necessary if you have called
2893 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
2894 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
2895 limit the overhead that wxWindows incurs by sending update UI events in idle time.
2896
2897 {\it flags} should be a bitlist of one or more of the following values.
2898
2899 \begin{verbatim}
2900 enum wxUpdateUI
2901 {
2902 wxUPDATE_UI_NONE = 0x0000, // No particular value
2903 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
2904 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
2905 };
2906 \end{verbatim}
2907
2908 If you are calling this function from an OnInternalIdle or OnIdle
2909 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
2910 this tells the window to only update the UI elements that need
2911 to be updated in idle time. Some windows update their elements
2912 only when necessary, for example when a menu is about to be shown.
2913 The following is an example of how to call UpdateWindowUI from
2914 an idle function.
2915
2916 \begin{verbatim}
2917 void MyWindow::OnInternalIdle()
2918 {
2919 if (wxUpdateUIEvent::CanUpdate(this))
2920 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
2921 }

2935
2936 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2937 the method will also call Validate() of all child windows.
