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.}

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.

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 \wxheading{Parameters}
146
147 \docparam{child}{Child window to add.}
148
149 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
150
151 \func{virtual void}{CaptureMouse}{\void}
152
153 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
154 release the capture.
155
156 Note that wxWindows maintains the stack of windows having captured the mouse
157 and when the mouse is released the capture returns to the window which had had
158 captured it previously and it is only really released if there were no previous
159 window. In particular, this means that you must release the mouse as many times
160 as you capture it.

183
184 \membersection{wxWindow::Centre}\label{wxwindowcentre}
185
186 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
187
188 Centres the window.
189
190 \wxheading{Parameters}
191
192 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
193 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
194 if you want to center the window on the entire screen and not on its
195 parent window.}
196
197 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
198 (it has no effect).
199
200 \wxheading{Remarks}
201
202 If the window is a top level one (i.e. doesn't have a parent), it will be
203 centered relative to the screen anyhow.

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

234 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
235
236 Centres the window on screen. This only works for top level windows -
237 otherwise, the window will still be centered on its parent.
238
239 \wxheading{Parameters}
240
241 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

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

281
282 \membersection{wxWindow::Close}\label{wxwindowclose}
283
284 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
285
286 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
287 handler usually tries to close the window. It doesn't close the window itself,
288 however.
289
290 \wxheading{Parameters}
291
292 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
293 of this window, {\tt true} if it cannot.}
294
295 \wxheading{Remarks}
296
297 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
298 an opportunity for the window to choose whether to destroy the window.
299 Usually it is only used with the top level windows (wxFrame and wxDialog
300 classes) as the others are not supposed to have any special OnClose() logic.
301
302 The close handler should check whether the window is being deleted forcibly,
303 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
304 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
305
306 {\it Note} that calling Close does not guarantee that the window will be
307 destroyed; but it provides a way to simulate a manual close of a window, which
308 may or may not be implemented by destroying the window. The default
309 implementation of wxDialog::OnCloseWindow does not necessarily delete the
310 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
311 the appropriate button event handler and may do anything at all.
312
313 To guarantee that the window will be destroyed, call
314 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

323
324 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
325
326 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
327
328 Converts a point or size from dialog units to pixels.
329
330 For the x dimension, the dialog units are multiplied by the average character width
331 and then divided by 4.
332
333 For the y dimension, the dialog units are multiplied by the average character height
334 and then divided by 8.
335
336 \wxheading{Remarks}
337
338 Dialog units are used for maintaining a dialog's proportions even if the font changes.
339 Dialogs created using Dialog Editor optionally use dialog units.
340
341 You can also use these functions programmatically. A convenience macro is defined:
342
343 {\small
344 \begin{verbatim}
345 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

405
406 Destroys the window safely. Use this function instead of the delete operator, since
407 different window classes can be destroyed differently. Frames and dialogs
408 are not destroyed immediately when this function is called -- they are added
409 to a list of windows to be deleted on idle time, when all the window's events
410 have been processed. This prevents problems with events being sent to non-existent
411 windows.
412

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

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

562
563 Find a window by its label. Depending on the type of window, the label may be a window title
564 or panel item label. If {\it parent} is NULL, the search will start from all top-level
565 frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy.

572 \membersection{wxWindow::Fit}\label{wxwindowfit}
573
574 \func{virtual void}{Fit}{\void}
575
576 Sizes the window so that it fits around its subwindows. This function won't do
577 anything if there are no subwindows and will only really work correctly if the
578 sizers are used for the subwindows layout. Also, if the window has exactly one
579 subwindow it is better (faster and the result is more precise as Fit adds some
580 margin to account for fuzziness of its calculations) to call
581
582 \begin{verbatim}
583 window->SetClientSize(child->GetSize());
584 \end{verbatim}
585
586 instead of calling Fit.
587
588 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}
589
590 \func{virtual void}{FitInside}{\void}
591
592 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
593 of a window. Mainly useful with scrolled windows to reset scrollbars after
594 sizing changes that do not trigger a size event, and/or scrolled windows without
595 an interior sizer. This function similarly won't do anything if there are no
596 subwindows.
597
598 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
599
600 \func{virtual void}{Freeze}{\void}
601
602 Freezes the window or, in other words, prevents any updates from taking place
603 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
604 be called to reenable window redrawing.
605
606 This method is useful for visual appearance optimization (for example, it
607 is a good idea to use it before inserting large amount of text into a
608 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
609 controls so it is mostly just a hint to wxWindows and not a mandatory

623
624 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
625 in one thing. GetBestSize should return the minimum untruncated size of the
626 window, while this method will return the largest of BestSize and any user
627 specified minimum size. ie. it is the minimum size the window should currently
628 be drawn at, not the minimal size it can possibly tolerate.

646 This functions returns the best acceptable minimal size for the window. For
647 example, for a static control, it will be the minimal size such that the
648 control label is not truncated. For windows containing subwindows (typically
649 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the

1781
1782 Pops up the given menu at the specified coordinates, relative to this

1822
1823 \docparam{handler}{Specifies the handler to be pushed.}
1824
1825 \wxheading{Remarks}
1826
1827 An event handler is an object that is capable of processing the events
1828 sent to a window. By default, the window is its own event handler, but
1829 an application may wish to substitute another, for example to allow
1830 central implementation of event-handling for a variety of different
1831 window classes.
1832
1833 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1834 an application to set up a chain of event handlers, where an event not handled by one event handler is
1835 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
1836 remove the event handler.

2116 calling this function.
2117
2118 Use this function with care under GTK as the new appearance of the window might

2143 This sets the size of the window client area in pixels. Using this function to size a window
2144 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not

2233
2234 \docparam{handler}{Specifies the handler to be set.}
2235
2236 \wxheading{Remarks}
2237
2238 An event handler is an object that is capable of processing the events
2239 sent to a window. By default, the window is its own event handler, but
2240 an application may wish to substitute another, for example to allow
2241 central implementation of event-handling for a variety of different
2242 window classes.
2243
2244 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2245 this sets up a chain of event handlers, where an event not handled by one event handler is
2246 handed to the next one in the chain.

2268 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2269 events are propagated upwards to the window parent recursively until a handler
2270 for them is found. Using this style allows to prevent them from being
2271 propagated beyond this window. Notice that wxDialog has this style on by
2272 default for the reasons explained in the
2273 \helpref{event processing overview}{eventprocessing}.}
2274 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2419 Let's say you wish to display 50 lines of text, using the same font.
2420 The window is sized so that you can only see 16 lines at a time.
2421
2422 You would use:
2423
2424 {\small%
2425 \begin{verbatim}
2426 SetScrollbar(wxVERTICAL, 0, 16, 50);
2427 \end{verbatim}
2428 }
2429
2430 Note that with the window at this size, the thumb position can never go
2431 above 50 minus 16, or 34.
2432
2433 You can determine how many lines are currently visible by dividing the current view
2434 size by the character height in pixels.
2435
2436 When defining your own scrollbar behaviour, you will always need to recalculate
2437 the scrollbar settings when the window size changes. You could therefore put your
2438 scrollbar calculations and SetScrollbar
2439 call into a function named AdjustScrollbars, which can be called initially and also
2440 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2461
2462 \wxheading{Remarks}
2463
2464 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2465 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2466 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2467 value has to be adjusted when the window is resized, since the page size will have changed.
2468
2469 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2470 the thumb changes size to reflect the page size relative to the length of the document. When the
2471 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2472 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2473 disappear.
2474
2475 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2476 handling of pages and ranges.

2528
2529 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2530 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2531 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2532 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2533 and usually the scrollbar will be automatically hidden.

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

2724 create a new validator of this type.
2725

2735
2736 \func{virtual void}{SetVirtualSizeHints}{\param{int}{ minW},\param{int}{ minH}, \param{int}{ maxW=-1}, \param{int}{ maxH=-1}}
2737
2738 Allows specification of minimum and maximum virtual window sizes.
2739 If a pair of values is not set (or set to -1), the default values
2740 will be used.
2741
2742 \wxheading{Parameters}
2743
2744 \docparam{minW}{Specifies the minimum width allowable.}
2745
2746 \docparam{minH}{Specifies the minimum height allowable.}

2762
2763 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
2764
2765 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
2766
2767 Sets the style of the window. Please note that some styles cannot be changed
2768 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2769 be called after changing the others for the change to take place immediately.

2778
2779 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2780
2781 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2782 for a top level window if you want to bring it to top, although this is not
2783 needed if Show() is called immediately after the frame creation.
2784
2785 \wxheading{Parameters}
2786
2787 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2788
2789 \wxheading{Return value}
2790

2860 \membersection{wxWindow::Update}\label{wxwindowupdate}
2861
2862 \func{virtual void}{Update}{\void}
2863
2864 Calling this method immediately repaints the invalidated area of the window
2865 while this would usually only happen when the flow of control returns to the
2866 event loop. Notice that this function doesn't refresh the window and does
2867 nothing if the window hadn't been already repainted. Use
2868 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2869 window unconditionally.
2870
2871 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
2872
2873 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
2874
2875 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
2876 the window. The particular implementation depends on the window; for
2877 example a wxToolBar will send an update UI event for each toolbar button,
2878 and a wxFrame will send an update UI event for each menubar menu item.
2879 You can call this function from your application to ensure that your
2880 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
2881 are concerned). This may be necessary if you have called
2882 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
2883 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
2884 limit the overhead that wxWindows incurs by sending update UI events in idle time.
2885
2886 {\it flags} should be a bitlist of one or more of the following values.
2887
2888 \begin{verbatim}
2889 enum wxUpdateUI
2890 {
2891 wxUPDATE_UI_NONE = 0x0000, // No particular value
2892 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
2893 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
2894 };
2895 \end{verbatim}
2896
2897 If you are calling this function from an OnInternalIdle or OnIdle
2898 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
2899 this tells the window to only update the UI elements that need
2900 to be updated in idle time. Some windows update their elements
2901 only when necessary, for example when a menu is about to be shown.
2902 The following is an example of how to call UpdateWindowUI from
2903 an idle function.
2904
2905 \begin{verbatim}
2906 void MyWindow::OnInternalIdle()
2907 {
2908 if (wxUpdateUIEvent::CanUpdate(this))
2909 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
2910 }

2924
2925 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2926 the method will also call Validate() of all child windows.
