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 only.}
44 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
45 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border. GTK only. }
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 the window
52 wants to get all char events - even for keys like TAB or ENTER which are
53 usually used for dialog navigation and which wouldn't be generated without
54 this style}
55 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
56 the window completely when its size is changed - you will have to repaint the
57 new window area manually if you use this style. Currently only has an effect for
58 Windows.}
59 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
60 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
61 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
62 disable them instead of hiding them when they are not needed (i.e. when the
63 size of the window is big enough to not require the scrollbars to navigate it).
64 This style is currently only implemented for wxMSW and wxUniversal and does
65 nothing on the other platforms.}
66 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
67 repainted, then children being painted over them. Windows only.}
68 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
69 a complete redraw of the window whenever it is resized instead of redrawing
70 just the part of the window affected by resizing. Note that this was the
71 behaviour by default before 2.5.1 release and that if you experience redraw
72 problems with the code which previously used to work you may want to try this.}

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

109
110 \func{}{wxWindow}{\void}
111
112 Default constructor.
113
114 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
115 \param{const wxPoint\& }{pos = wxDefaultPosition},
116 \param{const wxSize\& }{size = wxDefaultSize},
117 \param{long }{style = 0},
118 \param{const wxString\& }{name = wxPanelNameStr}}
119
120 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
121
122 \wxheading{Parameters}
123
124 \docparam{parent}{Pointer to a parent window.}
125
126 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
127
128 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
129 should generate a default position for the window. If using the wxWindow class directly, supply
130 an actual position.}
131
132 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
133 should generate a default size for the window. If no suitable size can be found, the
134 window will be sized to 20x20 pixels so that the window is visible but obviously not
135 correctly sized. }
136
137 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
138
139 \docparam{name}{Window name.}
140
141
142 \membersection{wxWindow::\destruct{wxWindow}}
143
144 \func{}{\destruct{wxWindow}}{\void}
145
146 Destructor. Deletes all subwindows, then deletes itself. Instead of using
147 the {\bf delete} operator explicitly, you should normally
148 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
149 can delete a window only when it is safe to do so, in idle time.

156
157
158 \membersection{wxWindow::AddChild}
159
160 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
161
162 Adds a child window. This is called automatically by window creation
163 functions so should not be required by the application programmer.
164
165 Notice that this function is mostly internal to wxWindows and shouldn't be
166 called by the user code.
167
168 \wxheading{Parameters}
169
170 \docparam{child}{Child window to add.}
171
172
173 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
174
175 \func{virtual void}{CaptureMouse}{\void}
176
177 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
178 release the capture.
179
180 Note that wxWindows maintains the stack of windows having captured the mouse
181 and when the mouse is released the capture returns to the window which had had
182 captured it previously and it is only really released if there were no previous
183 window. In particular, this means that you must release the mouse as many times
184 as you capture it.

210
211
212 \membersection{wxWindow::Centre}\label{wxwindowcentre}
213
214 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
215
216 Centres the window.
217
218 \wxheading{Parameters}
219
220 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
221 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
222 if you want to center the window on the entire screen and not on its
223 parent window.}
224
225 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
226 (it has no effect).
227
228 \wxheading{Remarks}
229
230 If the window is a top level one (i.e. doesn't have a parent), it will be
231 centered relative to the screen anyhow.

238 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
239
240 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
241
242 Centres the window on its parent. This is a more readable synonym for
243 \helpref{Centre}{wxwindowcentre}.
244
245 \wxheading{Parameters}
246
247 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
248 or {\tt wxBOTH}.}
249
250 \wxheading{Remarks}
251
252 This methods provides for a way to center top level windows over their
253 parents instead of the entire screen. If there is no parent or if the
254 window is not a top level window, then behaviour is the same as
255 \helpref{wxWindow::Centre}{wxwindowcentre}.

263
264 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
265
266 Centres the window on screen. This only works for top level windows -
267 otherwise, the window will still be centered on its parent.
268
269 \wxheading{Parameters}
270
271 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

313
314
315 \membersection{wxWindow::Close}\label{wxwindowclose}
316
317 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
318
319 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
320 handler usually tries to close the window. It doesn't close the window itself,
321 however.
322
323 \wxheading{Parameters}
324
325 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
326 of this window, {\tt true} if it cannot.}
327
328 \wxheading{Remarks}
329
330 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
331 an opportunity for the window to choose whether to destroy the window.
332 Usually it is only used with the top level windows (wxFrame and wxDialog
333 classes) as the others are not supposed to have any special OnClose() logic.
334
335 The close handler should check whether the window is being deleted forcibly,
336 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
337 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
338
339 {\it Note} that calling Close does not guarantee that the window will be
340 destroyed; but it provides a way to simulate a manual close of a window, which
341 may or may not be implemented by destroying the window. The default
342 implementation of wxDialog::OnCloseWindow does not necessarily delete the
343 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
344 the appropriate button event handler and may do anything at all.
345
346 To guarantee that the window will be destroyed, call
347 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

357
358 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
359
360 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
361
362 Converts a point or size from dialog units to pixels.
363
364 For the x dimension, the dialog units are multiplied by the average character width
365 and then divided by 4.
366
367 For the y dimension, the dialog units are multiplied by the average character height
368 and then divided by 8.
369
370 \wxheading{Remarks}
371
372 Dialog units are used for maintaining a dialog's proportions even if the font changes.
373 Dialogs created using Dialog Editor optionally use dialog units.
374
375 You can also use these functions programmatically. A convenience macro is defined:
376
377 {\small
378 \begin{verbatim}
379 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

441
442 Destroys the window safely. Use this function instead of the delete operator, since
443 different window classes can be destroyed differently. Frames and dialogs
444 are not destroyed immediately when this function is called -- they are added
445 to a list of windows to be deleted on idle time, when all the window's events
446 have been processed. This prevents problems with events being sent to non-existent
447 windows.
448
449 \wxheading{Return value}

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

520 Enable or disable the window for user input. Note that when a parent window is
521 disabled, all of its children are disabled as well and they are reenabled again
522 when the parent is.

620
621 \func{virtual void}{Fit}{\void}
622
623 Sizes the window so that it fits around its subwindows. This function won't do
624 anything if there are no subwindows and will only really work correctly if the
625 sizers are used for the subwindows layout. Also, if the window has exactly one
626 subwindow it is better (faster and the result is more precise as Fit adds some
627 margin to account for fuzziness of its calculations) to call
628
629 \begin{verbatim}
630 window->SetClientSize(child->GetSize());

632
633 instead of calling Fit.

637
638 \func{virtual void}{FitInside}{\void}
639
640 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
641 of a window. Mainly useful with scrolled windows to reset scrollbars after
642 sizing changes that do not trigger a size event, and/or scrolled windows without
643 an interior sizer. This function similarly won't do anything if there are no
644 subwindows.

651 Freezes the window or, in other words, prevents any updates from taking place
652 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
653 be called to reenable window redrawing.
654
655 This method is useful for visual appearance optimization (for example, it
656 is a good idea to use it before inserting large amount of text into a
657 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
658 controls so it is mostly just a hint to wxWindows and not a mandatory

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

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

1934 An event handler is an object that is capable of processing the events

1937 central implementation of event-handling for a variety of different
1938 window classes.
1939
1940 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2203 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2204
2205 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2206
2207 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2208 be called automatically when the window is resized. It is called implicitly by
2209 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2210 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2211 manually or otherwise the window layout won't be correctly updated when its
2212 size changes.
2213
2214 \wxheading{Parameters}
2215
2216 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called
2217 from within wxWindow::OnSize functions.}

2228 Sets the background colour of the window.
2229
2230 \wxheading{Parameters}
2231
2232 \docparam{colour}{The colour to be used as the background colour.}
2233
2234 \wxheading{Remarks}
2235
2236 The background colour is usually painted by the default\rtfsp
2237 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2238 under Windows and automatically under GTK.
2239
2240 Note that setting the background colour does not cause an immediate refresh, so you
2241 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2242 calling this function.
2243
2244 Use this function with care under GTK+ as the new appearance of the window might
2245 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2246 look as the user wishes with run-time loadable modules.

2268
2269 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2270
2271 This sets the size of the window client area in pixels. Using this function to size a window
2272 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2273 worry about what dimensions the border or title bar have when trying to fit the window
2274 around panel items, for example.
2275
2276 \wxheading{Parameters}
2277
2278 \docparam{width}{The required client area width.}
2279
2280 \docparam{height}{The required client area height.}

2325 \func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2326
2327 Sets the window to have the given layout constraints. The window
2328 will then own the object, and will take care of its deletion.
2329 If an existing layout constraints object is already owned by the
2330 window, it will be deleted.
2331
2332 \wxheading{Parameters}
2333
2334 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2335 constraints.}
2336
2337 \wxheading{Remarks}
2338
2339 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2340 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2341 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2365 \wxheading{Parameters}
2366
2367 \docparam{handler}{Specifies the handler to be set.}
2368
2369 \wxheading{Remarks}
2370
2371 An event handler is an object that is capable of processing the events
2372 sent to a window. By default, the window is its own event handler, but
2373 an application may wish to substitute another, for example to allow
2374 central implementation of event-handling for a variety of different
2375 window classes.
2376
2377 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2378 this sets up a chain of event handlers, where an event not handled by one event handler is
2379 handed to the next one in the chain.

2402 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2403 events are propagated upwards to the window parent recursively until a handler
2404 for them is found. Using this style allows to prevent them from being
2405 propagated beyond this window. Notice that wxDialog has this style on by
2406 default for the reasons explained in the
2407 \helpref{event processing overview}{eventprocessing}.}
2408 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2409 window from being used as an implicit parent for the dialogs which were
2410 created without a parent. It is useful for the windows which can disappear at
2411 any moment as creating children of such windows results in fatal problems.}
2412 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the

2414 a wxEVT\_HELP event if the user clicked on an application window.
2415 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2416 you should use the style of
2417 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2418 frames having this style (the dialogs don't have minimize nor maximize box by

2562 Let's say you wish to display 50 lines of text, using the same font.
2563 The window is sized so that you can only see 16 lines at a time.
2564
2565 You would use:
2566
2567 {\small%
2568 \begin{verbatim}
2569 SetScrollbar(wxVERTICAL, 0, 16, 50);
2570 \end{verbatim}
2571 }
2572
2573 Note that with the window at this size, the thumb position can never go
2574 above 50 minus 16, or 34.
2575
2576 You can determine how many lines are currently visible by dividing the current view
2577 size by the character height in pixels.
2578
2579 When defining your own scrollbar behaviour, you will always need to recalculate
2580 the scrollbar settings when the window size changes. You could therefore put your
2581 scrollbar calculations and SetScrollbar
2582 call into a function named AdjustScrollbars, which can be called initially and also
2583 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2605
2606 \wxheading{Remarks}
2607
2608 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2609 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2610 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2611 value has to be adjusted when the window is resized, since the page size will have changed.
2612
2613 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2614 the thumb changes size to reflect the page size relative to the length of the document. When the
2615 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2616 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2617 disappear.
2618
2619 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2620 handling of pages and ranges.

2674
2675 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2676 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2677 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2678 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2679 and usually the scrollbar will be automatically hidden.

2723
2724 \docparam{sizeFlags}{Indicates the interpretation of other parameters. It is a bit list of the following:
2725
2726 {\bf wxSIZE\_AUTO\_WIDTH}: a -1 width value is taken to indicate
2727 a wxWindows-supplied default width.\\
2728 {\bf wxSIZE\_AUTO\_HEIGHT}: a -1 height value is taken to indicate
2729 a wxWindows-supplied default width.\\
2730 {\bf wxSIZE\_AUTO}: -1 size values are taken to indicate

2791 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
2792
2793 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2794
2795 Sets the window to have the given layout sizer. The window
2796 will then own the object, and will take care of its deletion.
2797 If an existing layout constraints object is already owned by the
2798 window, it will be deleted if the deleteOld parameter is true.
2799
2800 Note that this function will also call
2801 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
2802 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
2803
2804 \wxheading{Parameters}
2805
2806 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
2807 the window's sizer. See below.}
2808
2809 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
2810 Pass false if you wish to handle deleting the old sizer yourself.}
2811
2812 \wxheading{Remarks}
2813
2814 SetSizer now enables and disables Layout automatically, but prior to wxWindows 2.3.3
2815 the following applied:
2816
2817 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2818 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2819 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2820 only the sizer will have effect.

2849
2850 This function tells a window if it should use the system's "theme" code
2851 to draw the windows' background instead if its own background drawing
2852 code. This does not always have any effect since the underlying platform
2853 obviously needs to support the notion of themes in user defined windows.
2854 One such platform is GTK+ where windows can have (very colourful) backgrounds
2855 defined by a user's selected theme.
2856
2857 Dialogs, notebook pages and the status bar have this flag set to true
2858 by default so that the default look and feel is simulated best.

3025
3026 \func{virtual void}{Update}{\void}
3027
3028 Calling this method immediately repaints the invalidated area of the window
3029 while this would usually only happen when the flow of control returns to the
3030 event loop. Notice that this function doesn't refresh the window and does
3031 nothing if the window hadn't been already repainted. Use
3032 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3033 window unconditionally.

3036 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3037
3038 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
3039
3040 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3041 the window. The particular implementation depends on the window; for
3042 example a wxToolBar will send an update UI event for each toolbar button,
3043 and a wxFrame will send an update UI event for each menubar menu item.
3044 You can call this function from your application to ensure that your
3045 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3046 are concerned). This may be necessary if you have called
3047 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3048 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3049 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3050
3051 {\it flags} should be a bitlist of one or more of the following values.
3052
3053 \begin{verbatim}
3054 enum wxUpdateUI
3055 {
3056 wxUPDATE_UI_NONE = 0x0000, // No particular value
3057 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3058 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3059 };
3060 \end{verbatim}
3061
3062 If you are calling this function from an OnInternalIdle or OnIdle
3063 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3064 this tells the window to only update the UI elements that need
3065 to be updated in idle time. Some windows update their elements
3066 only when necessary, for example when a menu is about to be shown.
3067 The following is an example of how to call UpdateWindowUI from
3068 an idle function.
3069
3070 \begin{verbatim}
3071 void MyWindow::OnInternalIdle()
3072 {
3073 if (wxUpdateUIEvent::CanUpdate(this))
