1 \section{\class{wxWindow}}\label{wxwindow}
2
3 wxWindow is the base class for all windows and represents any visible objecto n
4 screen. All controls, top level windows and so on are windows. Sizers and
5 device contexts are not, however, as they don't appear on screen themselves.
6
7 Please note that all children of the window will be deleted automatically by
8 the destructor before the window itself is deleted which means that you don't
9 have to worry about deleting them manually. Please see the \helpref{window
10 deletion overview}{windowdeletionoverview} for more information.
11
12 Also note that in this, and many others, wxWindows classes some
13 \texttt{GetXXX()} methods may be overloaded (as, for example,
14 \helpref{GetSize}{wxwindowgetsize} or
15 \helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
16 are non-virtual because having multiple virtual functions with the same name
17 results in a virtual function name hiding at the derived class level (in
18 English, this means that the derived class has to override all overloaded
19 variants if it overrides any of them). To allow overriding them in the derived
20 class, wxWindows uses a unique protected virtual \texttt{DoGetXXX()} method
21 and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
22 changes the behaviour of the latter.

34 \wxheading{Window styles}
35
36 The following styles can apply to all windows, although they will not always make sense for a particular
37 window class or on all platforms.
38
39 \twocolwidtha{5cm}%
40 \begin{twocollist}\itemsep=0pt
41 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
42 for this style. }
43 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
44 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
45 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
46 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
47 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
48 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
49 events. Windows only.}
50 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
51 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
52 the window wants to get all char/key events for all keys - even for
53 keys like TAB or ENTER which are usually used for dialog navigation
54 and which wouldn't be generated without this style. If you need to
55 use this style in order to get the arrows or etc., but would still like to have
56 normal keyboard navigation take place, you should create and send a
57 wxNavigationKeyEvent in response to the key events for Tab and
58 Shift-Tab.}
59 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
60 the window completely when its size is changed - you will have to repaint the
61 new window area manually if you use this style. Currently only has an effect for
62 Windows.}
63 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
64 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
65 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
66 disable them instead of hiding them when they are not needed (i.e. when the
67 size of the window is big enough to not require the scrollbars to navigate it).
68 This style is currently only implemented for wxMSW and wxUniversal and does
69 nothing on the other platforms.}
70 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
71 repainted, then children being painted over them. Windows only.}
72 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
73 a complete redraw of the window whenever it is resized instead of redrawing
74 just the part of the window affected by resizing. Note that this was the
75 behaviour by default before 2.5.1 release and that if you experience redraw
76 problems with the code which previously used to work you may want to try this.}

81 \wxheading{Extra window styles}
82
83 The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}.
84
85 \twocolwidtha{5cm}%
86 \begin{twocollist}\itemsep=0pt
87 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
88 only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
89 descend into all subwindows.}
90 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
91 parent window and so on recursively by default. Using this flag for the
92 given window allows to block this propagation at this window, i.e. prevent
93 the events from being propagated further upwards. Dialogs have this
94 flag on by default.}
95 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
96 be used with transient windows as otherwise there is the risk of creating a
97 dialog/frame with this window as a parent which would lead to a crash if the
98 parent is destroyed before the child.}
99 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
100 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
101 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
102 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

119 \param{const wxPoint\& }{pos = wxDefaultPosition},
120 \param{const wxSize\& }{size = wxDefaultSize},
121 \param{long }{style = 0},

123
124 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
125
126 \wxheading{Parameters}
127
128 \docparam{parent}{Pointer to a parent window.}
129
130 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
131
132 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
133 should generate a default position for the window. If using the wxWindow class directly, supply
134 an actual position.}
135
136 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
137 should generate a default size for the window. If no suitable size can be found, the
138 window will be sized to 20x20 pixels so that the window is visible but obviously not
139 correctly sized. }
140
141 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
142
143 \docparam{name}{Window name.}
144
145
146 \membersection{wxWindow::\destruct{wxWindow}}
147
148 \func{}{\destruct{wxWindow}}{\void}
149
150 Destructor. Deletes all subwindows, then deletes itself. Instead of using
151 the {\bf delete} operator explicitly, you should normally
152 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
153 can delete a window only when it is safe to do so, in idle time.

162 \membersection{wxWindow::AddChild}
163
164 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
165
166 Adds a child window. This is called automatically by window creation
167 functions so should not be required by the application programmer.
168
169 Notice that this function is mostly internal to wxWindows and shouldn't be
170 called by the user code.
171
172 \wxheading{Parameters}
173
174 \docparam{child}{Child window to add.}
175
176
177 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
178
179 \func{virtual void}{CaptureMouse}{\void}
180
181 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
182 release the capture.
183
184 Note that wxWindows maintains the stack of windows having captured the mouse
185 and when the mouse is released the capture returns to the window which had had
186 captured it previously and it is only really released if there were no previous
187 window. In particular, this means that you must release the mouse as many times
188 as you capture it.

216 \membersection{wxWindow::Centre}\label{wxwindowcentre}
217
218 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
219
220 Centres the window.
221
222 \wxheading{Parameters}
223
224 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
225 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
226 if you want to center the window on the entire screen and not on its
227 parent window.}
228
229 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
230 (it has no effect).
231
232 \wxheading{Remarks}
233
234 If the window is a top level one (i.e. doesn't have a parent), it will be
235 centered relative to the screen anyhow.

247 \helpref{Centre}{wxwindowcentre}.
248
249 \wxheading{Parameters}

251 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
252 or {\tt wxBOTH}.}
253
254 \wxheading{Remarks}
255
256 This methods provides for a way to center top level windows over their
257 parents instead of the entire screen. If there is no parent or if the
258 window is not a top level window, then behaviour is the same as
259 \helpref{wxWindow::Centre}{wxwindowcentre}.

269
270 Centres the window on screen. This only works for top level windows -
271 otherwise, the window will still be centered on its parent.
272
273 \wxheading{Parameters}
274
275 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

318
319 \membersection{wxWindow::Close}\label{wxwindowclose}
320
321 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
322
323 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
324 handler usually tries to close the window. It doesn't close the window itself,
325 however.
326
327 \wxheading{Parameters}
328
329 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
330 of this window, {\tt true} if it cannot.}
331
332 \wxheading{Remarks}
333
334 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
335 an opportunity for the window to choose whether to destroy the window.
336 Usually it is only used with the top level windows (wxFrame and wxDialog
337 classes) as the others are not supposed to have any special OnClose() logic.
338
339 The close handler should check whether the window is being deleted forcibly,
340 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
341 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
342
343 {\it Note} that calling Close does not guarantee that the window will be
344 destroyed; but it provides a way to simulate a manual close of a window, which
345 may or may not be implemented by destroying the window. The default
346 implementation of wxDialog::OnCloseWindow does not necessarily delete the
347 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
348 the appropriate button event handler and may do anything at all.
349
350 To guarantee that the window will be destroyed, call
351 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

361
362 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
363
364 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
365
366 Converts a point or size from dialog units to pixels.
367
368 For the x dimension, the dialog units are multiplied by the average character width
369 and then divided by 4.
370
371 For the y dimension, the dialog units are multiplied by the average character height
372 and then divided by 8.
373
374 \wxheading{Remarks}
375
376 Dialog units are used for maintaining a dialog's proportions even if the font changes.
377 Dialogs created using Dialog Editor optionally use dialog units.
378
379 You can also use these functions programmatically. A convenience macro is defined:
380
381 {\small
382 \begin{verbatim}
383 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

445
446 Destroys the window safely. Use this function instead of the delete operator, since
447 different window classes can be destroyed differently. Frames and dialogs
448 are not destroyed immediately when this function is called -- they are added
449 to a list of windows to be deleted on idle time, when all the window's events
450 have been processed. This prevents problems with events being sent to non-existent
451 windows.
452

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

624
625 \func{virtual void}{Fit}{\void}
626
627 Sizes the window so that it fits around its subwindows. This function won't do
628 anything if there are no subwindows and will only really work correctly if the
629 sizers are used for the subwindows layout. Also, if the window has exactly one
630 subwindow it is better (faster and the result is more precise as Fit adds some
631 margin to account for fuzziness of its calculations) to call
632
633 \begin{verbatim}
634 window->SetClientSize(child->GetSize());

645 of a window. Mainly useful with scrolled windows to reset scrollbars after
646 sizing changes that do not trigger a size event, and/or scrolled windows without
647 an interior sizer. This function similarly won't do anything if there are no
648 subwindows.

655 Freezes the window or, in other words, prevents any updates from taking place
656 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
657 be called to reenable window redrawing.
658
659 This method is useful for visual appearance optimization (for example, it
660 is a good idea to use it before inserting large amount of text into a
661 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
662 controls so it is mostly just a hint to wxWindows and not a mandatory

710 example, for a static control, it will be the minimal size such that the
711 control label is not truncated. For windows containing subwindows (typically

1952 An event handler is an object that is capable of processing the events

1955 central implementation of event-handling for a variety of different
1956 window classes.
1957
1958 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1959 an application to set up a chain of event handlers, where an event not handled by one event handler is
1960 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2187
2188 \wxheading{Parameters}
2189
2190 \docparam{dx}{Amount to scroll horizontally.}
2191
2192 \docparam{dy}{Amount to scroll vertically.}

2197
2198 \wxheading{Remarks}

2221 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2222
2223 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2224
2225 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2226 be called automatically when the window is resized. It is called implicitly by
2227 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2228 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2229 manually or otherwise the window layout won't be correctly updated when its
2230 size changes.
2231
2232 \wxheading{Parameters}
2233
2234 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called
2235 from within wxWindow::OnSize functions.}

2246 Sets the background colour of the window.
2247
2248 \wxheading{Parameters}
2249
2250 \docparam{colour}{The colour to be used as the background colour.}
2251
2252 \wxheading{Remarks}
2253
2254 The background colour is usually painted by the default\rtfsp
2255 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2256 under Windows and automatically under GTK.
2257
2258 Note that setting the background colour does not cause an immediate refresh, so you
2259 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2260 calling this function.
2261
2262 Use this function with care under GTK+ as the new appearance of the window might
2263 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2264 look as the user wishes with run-time loadable modules.

2286
2287 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2288
2289 This sets the size of the window client area in pixels. Using this function to size a window
2290 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2291 worry about what dimensions the border or title bar have when trying to fit the window
2292 around panel items, for example.
2293
2294 \wxheading{Parameters}
2295
2296 \docparam{width}{The required client area width.}
2297
2298 \docparam{height}{The required client area height.}

2317 remove itself from the sizer when it is destroyed.

2323
2324 % VZ: the docs are correct, if the code doesn't behave like this, it must be

2326 Sets the window's cursor. Notice that the window cursor also sets it for the
2327 children of the window implicitly.
2328
2329 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2330 be reset back to default.

2342
2343 \func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2344
2345 Sets the window to have the given layout constraints. The window
2346 will then own the object, and will take care of its deletion.
2347 If an existing layout constraints object is already owned by the
2348 window, it will be deleted.
2349
2350 \wxheading{Parameters}
2351
2352 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2353 constraints.}
2354
2355 \wxheading{Remarks}
2356
2357 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2358 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2359 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2360 sizer will have effect.

2383 \wxheading{Parameters}
2384
2385 \docparam{handler}{Specifies the handler to be set.}
2386
2387 \wxheading{Remarks}
2388
2389 An event handler is an object that is capable of processing the events
2390 sent to a window. By default, the window is its own event handler, but
2391 an application may wish to substitute another, for example to allow
2392 central implementation of event-handling for a variety of different
2393 window classes.
2394
2395 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2396 this sets up a chain of event handlers, where an event not handled by one event handler is
2397 handed to the next one in the chain.

2415 \twocolwidtha{5cm}%
2416 \begin{twocollist}\itemsep=0pt
2417 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2418 and Validate() methods will recursively descend into all children of the
2419 window if it has this style flag set.}
2420 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2421 events are propagated upwards to the window parent recursively until a handler
2422 for them is found. Using this style allows to prevent them from being
2423 propagated beyond this window. Notice that wxDialog has this style on by
2424 default for the reasons explained in the
2425 \helpref{event processing overview}{eventprocessing}.}
2426 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2427 window from being used as an implicit parent for the dialogs which were
2428 created without a parent. It is useful for the windows which can disappear at
2429 any moment as creating children of such windows results in fatal problems.}
2430 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2431 caption. When pressed, Windows will go into a context-sensitive help mode and wxWindows will send
2432 a wxEVT\_HELP event if the user clicked on an application window.
2433 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2434 you should use the style of
2435 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2436 frames having this style (the dialogs don't have minimize nor maximize box by

2584 Let's say you wish to display 50 lines of text, using the same font.
2585 The window is sized so that you can only see 16 lines at a time.
2586
2587 You would use:
2588
2589 {\small%
2590 \begin{verbatim}
2591 SetScrollbar(wxVERTICAL, 0, 16, 50);
2592 \end{verbatim}
2593 }
2594
2595 Note that with the window at this size, the thumb position can never go
2596 above 50 minus 16, or 34.
2597
2598 You can determine how many lines are currently visible by dividing the current view
2599 size by the character height in pixels.
2600
2601 When defining your own scrollbar behaviour, you will always need to recalculate
2602 the scrollbar settings when the window size changes. You could therefore put your
2603 scrollbar calculations and SetScrollbar
2604 call into a function named AdjustScrollbars, which can be called initially and also
2605 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2627
2628 \wxheading{Remarks}
2629
2630 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2631 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2632 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2633 value has to be adjusted when the window is resized, since the page size will have changed.
2634
2635 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2636 the thumb changes size to reflect the page size relative to the length of the document. When the
2637 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2638 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2639 disappear.
2640
2641 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2642 handling of pages and ranges.

2698 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2699 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2700 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2701 and usually the scrollbar will be automatically hidden.

2814
2815 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2816
2817 Sets the window to have the given layout sizer. The window
2818 will then own the object, and will take care of its deletion.
2819 If an existing layout constraints object is already owned by the
2820 window, it will be deleted if the deleteOld parameter is true.
2821
2822 Note that this function will also call
2823 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
2824 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.

2827
2828 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
2829 the window's sizer. See below.}

2835
2836 SetSizer now enables and disables Layout automatically, but prior to wxWindows 2.3.3
2837 the following applied:
2838
2839 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2840 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2841 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2842 only the sizer will have effect.

2871
2872 This function tells a window if it should use the system's "theme" code
2873 to draw the windows' background instead if its own background drawing
2874 code. This does not always have any effect since the underlying platform
2875 obviously needs to support the notion of themes in user defined windows.
2876 One such platform is GTK+ where windows can have (very colourful) backgrounds
2877 defined by a user's selected theme.
2878
2879 Dialogs, notebook pages and the status bar have this flag set to true
2880 by default so that the default look and feel is simulated best.

3048 \func{virtual void}{Update}{\void}
3049
3050 Calling this method immediately repaints the invalidated area of the window
3051 while this would usually only happen when the flow of control returns to the
3052 event loop. Notice that this function doesn't refresh the window and does
3053 nothing if the window hadn't been already repainted. Use
3054 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3055 window unconditionally.

3058 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3059
3060 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3061
3062 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3063 the window. The particular implementation depends on the window; for
3064 example a wxToolBar will send an update UI event for each toolbar button,
3065 and a wxFrame will send an update UI event for each menubar menu item.
3066 You can call this function from your application to ensure that your
3067 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3068 are concerned). This may be necessary if you have called
3069 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3070 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3071 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3072
3073 {\it flags} should be a bitlist of one or more of the following values.
3074
3075 \begin{verbatim}
3076 enum wxUpdateUI
3077 {
3078 wxUPDATE_UI_NONE = 0x0000, // No particular value
3079 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3080 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3081 };
3082 \end{verbatim}
3083
3084 If you are calling this function from an OnInternalIdle or OnIdle
3085 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3086 this tells the window to only update the UI elements that need
3087 to be updated in idle time. Some windows update their elements
3088 only when necessary, for example when a menu is about to be shown.
3089 The following is an example of how to call UpdateWindowUI from
3090 an idle function.
3091
3092 \begin{verbatim}
3093 void MyWindow::OnInternalIdle()
3094 {
3095 if (wxUpdateUIEvent::CanUpdate(this))
