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.

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

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

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

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

214
215 \membersection{wxWindow::Centre}\label{wxwindowcentre}
216
217 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
218
219 Centres the window.
220
221 \wxheading{Parameters}
222
223 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
224 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
225 if you want to center the window on the entire screen and not on its
226 parent window.}
227
228 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
229 (it has no effect).
230
231 \wxheading{Remarks}
232
233 If the window is a top level one (i.e. doesn't have a parent), it will be
234 centered relative to the screen anyhow.

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

266
267 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
268
269 Centres the window on screen. This only works for top level windows -
270 otherwise, the window will still be centered on its parent.
271
272 \wxheading{Parameters}
273
274 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

317
318 \membersection{wxWindow::Close}\label{wxwindowclose}
319
320 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
321
322 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
323 handler usually tries to close the window. It doesn't close the window itself,
324 however.
325
326 \wxheading{Parameters}
327
328 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
329 of this window, {\tt true} if it cannot.}
330
331 \wxheading{Remarks}
332
333 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
334 an opportunity for the window to choose whether to destroy the window.
335 Usually it is only used with the top level windows (wxFrame and wxDialog
336 classes) as the others are not supposed to have any special OnClose() logic.
337
338 The close handler should check whether the window is being deleted forcibly,
339 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
340 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
341
342 {\it Note} that calling Close does not guarantee that the window will be
343 destroyed; but it provides a way to simulate a manual close of a window, which
344 may or may not be implemented by destroying the window. The default
345 implementation of wxDialog::OnCloseWindow does not necessarily delete the
346 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
347 the appropriate button event handler and may do anything at all.
348
349 To guarantee that the window will be destroyed, call
350 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

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

440
441 Destroys the window safely. Use this function instead of the delete operator, since
442 different window classes can be destroyed differently. Frames and dialogs
443 are not destroyed immediately when this function is called -- they are added
444 to a list of windows to be deleted on idle time, when all the window's events
445 have been processed. This prevents problems with events being sent to non-existent
446 windows.
447
448 \wxheading{Return value}

473 \membersection{wxWindow::DoUpdateWindowUI}\label{wxwindowdoupdatewindowui}
474
475 \func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}
476
477 Does the window-specific updating after processing the update event.
478 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
479 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
480 act appropriately. For example, to allow frame and dialog title updating, wxWindows

517
518 \func{virtual bool}{Enable}{\param{bool}{ enable = {\tt true}}}
519
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.
523
524 \wxheading{Parameters}

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

634 instead of calling Fit.

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

648 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

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

683
684 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
685 in one thing. GetBestSize should return the minimum untruncated size of the
686 window, while this method will return the largest of BestSize and any user
687 specified minimum size. ie. it is the minimum size the window should currently
688 be drawn at, not the minimal size it can possibly tolerate.

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

1953 An event handler is an object that is capable of processing the events

1956 central implementation of event-handling for a variety of different
1957 window classes.
1958
1959 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1960 an application to set up a chain of event handlers, where an event not handled by one event handler is
1961 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2191 \docparam{dx}{Amount to scroll horizontally.}
2192
2193 \docparam{dy}{Amount to scroll vertically.}
2194
2195 \docparam{rect}{Rectangle to invalidate. If this is NULL, the whole window is invalidated. If you
2196 pass a rectangle corresponding to the area of the window exposed by the scroll, your painting handler
2197 can optimize painting by checking for the invalidated region. This parameter is ignored under GTK.}
2198
2199 \wxheading{Remarks}
2200
2201 Use this function to optimise your scrolling implementations, to minimise the area that must be

2222 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2223
2224 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2225
2226 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2227 be called automatically when the window is resized. It is called implicitly by
2228 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2229 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2230 manually or otherwise the window layout won't be correctly updated when its
2231 size changes.
2232
2233 \wxheading{Parameters}
2234
2235 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called
2236 from within wxWindow::OnSize functions.}

2248
2249 \wxheading{Parameters}
2250
2251 \docparam{colour}{The colour to be used as the background colour.}
2252
2253 \wxheading{Remarks}
2254
2255 The background colour is usually painted by the default\rtfsp
2256 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2257 under Windows and automatically under GTK.
2258
2259 Note that setting the background colour does not cause an immediate refresh, so you
2260 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2261 calling this function.
2262
2263 Use this function with care under GTK+ as the new appearance of the window might
2264 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2265 look as the user wishes with run-time loadable modules.

2287
2288 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2289
2290 This sets the size of the window client area in pixels. Using this function to size a window
2291 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2292 worry about what dimensions the border or title bar have when trying to fit the window
2293 around panel items, for example.
2294
2295 \wxheading{Parameters}
2296
2297 \docparam{width}{The required client area width.}
2298
2299 \docparam{height}{The required client area height.}

2325 % VZ: the docs are correct, if the code doesn't behave like this, it must be

2327 Sets the window's cursor. Notice that the window cursor also sets it for the
2328 children of the window implicitly.
2329
2330 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2331 be reset back to default.

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

2385 \wxheading{Parameters}
2386
2387 \docparam{handler}{Specifies the handler to be set.}
2388
2389 \wxheading{Remarks}
2390
2391 An event handler is an object that is capable of processing the events
2392 sent to a window. By default, the window is its own event handler, but
2393 an application may wish to substitute another, for example to allow
2394 central implementation of event-handling for a variety of different
2395 window classes.
2396
2397 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2398 this sets up a chain of event handlers, where an event not handled by one event handler is
2399 handed to the next one in the chain.

2417 \twocolwidtha{5cm}%
2418 \begin{twocollist}\itemsep=0pt

2420 and Validate() methods will recursively descend into all children of the

2422 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2423 events are propagated upwards to the window parent recursively until a handler
2424 for them is found. Using this style allows to prevent them from being
2425 propagated beyond this window. Notice that wxDialog has this style on by
2426 default for the reasons explained in the
2427 \helpref{event processing overview}{eventprocessing}.}
2428 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2429 window from being used as an implicit parent for the dialogs which were
2430 created without a parent. It is useful for the windows which can disappear at
2431 any moment as creating children of such windows results in fatal problems.}
2432 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2433 caption. When pressed, Windows will go into a context-sensitive help mode and wxWindows will send
2434 a wxEVT\_HELP event if the user clicked on an application window.
2435 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2436 you should use the style of
2437 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the
2438 frames having this style (the dialogs don't have minimize nor maximize box by

2587 Let's say you wish to display 50 lines of text, using the same font.
2588 The window is sized so that you can only see 16 lines at a time.
2589
2590 You would use:
2591
2592 {\small%
2593 \begin{verbatim}
2594 SetScrollbar(wxVERTICAL, 0, 16, 50);
2595 \end{verbatim}
2596 }
2597
2598 Note that with the window at this size, the thumb position can never go
2599 above 50 minus 16, or 34.
2600
2601 You can determine how many lines are currently visible by dividing the current view
2602 size by the character height in pixels.
2603
2604 When defining your own scrollbar behaviour, you will always need to recalculate
2605 the scrollbar settings when the window size changes. You could therefore put your
2606 scrollbar calculations and SetScrollbar
2607 call into a function named AdjustScrollbars, which can be called initially and also
2608 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2631
2632 \wxheading{Remarks}
2633
2634 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2635 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2636 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2637 value has to be adjusted when the window is resized, since the page size will have changed.
2638
2639 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2640 the thumb changes size to reflect the page size relative to the length of the document. When the
2641 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2642 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2643 disappear.
2644
2645 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2646 handling of pages and ranges.

2702 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2703 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2704 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2705 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2706 and usually the scrollbar will be automatically hidden.

2819
2820 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
2821
2822 Sets the window to have the given layout sizer. The window
2823 will then own the object, and will take care of its deletion.
2824 If an existing layout constraints object is already owned by the
2825 window, it will be deleted if the deleteOld parameter is true.
2826
2827 Note that this function will also call
2828 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
2829 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.

2831 \wxheading{Parameters}
2832
2833 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
2834 the window's sizer. See below.}

2843
2844 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2845 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2846 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2847 only the sizer will have effect.

2876
2877 This function tells a window if it should use the system's "theme" code
2878 to draw the windows' background instead if its own background drawing
2879 code. This does not always have any effect since the underlying platform
2880 obviously needs to support the notion of themes in user defined windows.
2881 One such platform is GTK+ where windows can have (very colourful) backgrounds
2882 defined by a user's selected theme.
2883
2884 Dialogs, notebook pages and the status bar have this flag set to true
2885 by default so that the default look and feel is simulated best.

3056 \func{virtual void}{Update}{\void}
3057
3058 Calling this method immediately repaints the invalidated area of the window
3059 while this would usually only happen when the flow of control returns to the
3060 event loop. Notice that this function doesn't refresh the window and does
3061 nothing if the window hadn't been already repainted. Use
3062 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3063 window unconditionally.

3066 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3067
3068 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3069
3070 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3071 the window. The particular implementation depends on the window; for
3072 example a wxToolBar will send an update UI event for each toolbar button,
3073 and a wxFrame will send an update UI event for each menubar menu item.
3074 You can call this function from your application to ensure that your
3075 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3076 are concerned). This may be necessary if you have called
3077 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3078 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3079 limit the overhead that wxWindows incurs by sending update UI events in idle time.
3080
3081 {\it flags} should be a bitlist of one or more of the following values.
3082
3083 \begin{verbatim}
3084 enum wxUpdateUI
3085 {
3086 wxUPDATE_UI_NONE = 0x0000, // No particular value
3087 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3088 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3089 };
3090 \end{verbatim}
3091
3092 If you are calling this function from an OnInternalIdle or OnIdle
3093 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3094 this tells the window to only update the UI elements that need
3095 to be updated in idle time. Some windows update their elements
3096 only when necessary, for example when a menu is about to be shown.
3097 The following is an example of how to call UpdateWindowUI from
3098 an idle function.
3099
3100 \begin{verbatim}
3101 void MyWindow::OnInternalIdle()
3102 {
3103 if (wxUpdateUIEvent::CanUpdate(this))
