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

44 \wxheading{Window styles}
45
46 The following styles can apply to all windows, although they will not always make sense for a particular
47 window class or on all platforms.
48
49 \twocolwidtha{5cm}%
50 \begin{twocollist}\itemsep=0pt
51 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
52 for this style. }
53 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
54 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
55 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
56 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
57 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
58 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
59 events. Windows only.}
60 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
61 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
62 the window wants to get all char/key events for all keys - even for
63 keys like TAB or ENTER which are usually used for dialog navigation
64 and which wouldn't be generated without this style. If you need to
65 use this style in order to get the arrows or etc., but would still like to have
66 normal keyboard navigation take place, you should create and send a
67 wxNavigationKeyEvent in response to the key events for Tab and
68 Shift-Tab.}
69 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
70 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
71 and no longer has an effect.}
72 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
73 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
74 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
75 disable them instead of hiding them when they are not needed (i.e. when the
76 size of the window is big enough to not require the scrollbars to navigate it).
77 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
78 nothing on the other platforms.}
79 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80 repainted, then children being painted over them. Windows only.}
81 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
82 a complete redraw of the window whenever it is resized instead of redrawing
83 just the part of the window affected by resizing. Note that this was the
84 behaviour by default before 2.5.1 release and that if you experience redraw
85 problems with code which previously used to work you may want to try this.
86 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
87 done on other platforms.}

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

124 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
125
126 \func{}{wxWindow}{\void}
127
128 Default constructor.
129
130 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
131 \param{const wxPoint\& }{pos = wxDefaultPosition},
132 \param{const wxSize\& }{size = wxDefaultSize},
133 \param{long }{style = 0},
134 \param{const wxString\& }{name = wxPanelNameStr}}
135
136 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
137
138 \wxheading{Parameters}
139
140 \docparam{parent}{Pointer to a parent window.}
141
142 \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
143
144 \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
145 should generate a default position for the window. If using the wxWindow class directly, supply
146 an actual position.}
147
148 \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
149 should generate a default size for the window. If no suitable size can be found, the
150 window will be sized to 20x20 pixels so that the window is visible but obviously not
151 correctly sized. }
152
153 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
154
155 \docparam{name}{Window name.}
156
157
158 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
159
160 \func{}{\destruct{wxWindow}}{\void}
161
162 Destructor. Deletes all subwindows, then deletes itself. Instead of using
163 the {\bf delete} operator explicitly, you should normally
164 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
165 can delete a window only when it is safe to do so, in idle time.

172
173
174 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
175
176 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
177
178 Adds a child window. This is called automatically by window creation
179 functions so should not be required by the application programmer.
180
181 Notice that this function is mostly internal to wxWidgets and shouldn't be
182 called by the user code.
183
184 \wxheading{Parameters}
185
186 \docparam{child}{Child window to add.}
187
188
189 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
190
191 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
192
193 Sets the cached best size value.
194
195
196 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
197
198 \func{virtual void}{CaptureMouse}{\void}
199
200 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
201 release the capture.
202
203 Note that wxWidgets maintains the stack of windows having captured the mouse
204 and when the mouse is released the capture returns to the window which had had
205 captured it previously and it is only really released if there were no previous
206 window. In particular, this means that you must release the mouse as many times
207 as you capture it, unless the window receives
208 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
209
210 Any application which captures the mouse in the beginning of some operation
211 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
212 and cancel this operation when it receives the event. The event handler must
213 not recapture mouse.

222
223 \func{void}{Center}{\param{int}{ direction}}
224
225 A synonym for \helpref{Centre}{wxwindowcentre}.
226
227
228 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}

238
239 A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}.
240
241
242 \membersection{wxWindow::Centre}\label{wxwindowcentre}
243
244 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
245
246 Centres the window.
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}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
252 if you want to center the window on the entire screen and not on its
253 parent window.}
254
255 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
256 (it has no effect).
257
258 \wxheading{Remarks}
259
260 If the window is a top level one (i.e. doesn't have a parent), it will be
261 centered relative to the screen anyhow.

268 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
269
270 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
271
272 Centres the window on its parent. This is a more readable synonym for
273 \helpref{Centre}{wxwindowcentre}.
274
275 \wxheading{Parameters}
276
277 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
278 or {\tt wxBOTH}.}
279
280 \wxheading{Remarks}
281
282 This methods provides for a way to center top level windows over their
283 parents instead of the entire screen. If there is no parent or if the
284 window is not a top level window, then behaviour is the same as
285 \helpref{wxWindow::Centre}{wxwindowcentre}.

292 \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
293
294 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
295
296 Centres the window on screen. This only works for top level windows -
297 otherwise, the window will still be centered on its parent.
298
299 \wxheading{Parameters}
300
301 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
302 or {\tt wxBOTH}.}

310
311 \func{void}{ClearBackground}{\void}
312
313 Clears the window by filling it with the current background colour. Does not
314 cause an erase background event to be generated.
315
316
317 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
318
319 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
320
321 \perlnote{In wxPerl this method returns a 2-element list instead of
322 modifying its parameters.}
323
324 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
325
326 Converts to screen coordinates from coordinates relative to this window.
327
328 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
329 a screen coordinate will be passed out.}
330
331 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
332 a screen coordinate will be passed out.}
333
334 \docparam{pt}{The client position for the second form of the function.}
335
336 \pythonnote{In place of a single overloaded method name, wxPython
337 implements the following methods:\par
338 \indented{2cm}{\begin{twocollist}

343
344
345 \membersection{wxWindow::Close}\label{wxwindowclose}
346
347 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
348
349 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
350 handler usually tries to close the window. It doesn't close the window itself,
351 however.
352
353 \wxheading{Parameters}
354
355 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
356 of this window, {\tt true} if it cannot.}
357
358 \wxheading{Remarks}
359
360 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
361 an opportunity for the window to choose whether to destroy the window.
362 Usually it is only used with the top level windows (wxFrame and wxDialog
363 classes) as the others are not supposed to have any special OnClose() logic.
364
365 The close handler should check whether the window is being deleted forcibly,
366 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
367 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
368
369 {\it Note} that calling Close does not guarantee that the window will be
370 destroyed; but it provides a way to simulate a manual close of a window, which
371 may or may not be implemented by destroying the window. The default
372 implementation of wxDialog::OnCloseWindow does not necessarily delete the
373 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
374 the appropriate button event handler and may do anything at all.
375
376 To guarantee that the window will be destroyed, call
377 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

387
388 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
389
390 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
391
392 Converts a point or size from dialog units to pixels.
393
394 For the x dimension, the dialog units are multiplied by the average character width
395 and then divided by 4.
396
397 For the y dimension, the dialog units are multiplied by the average character height
398 and then divided by 8.
399
400 \wxheading{Remarks}
401
402 Dialog units are used for maintaining a dialog's proportions even if the font changes.
403
404 You can also use these functions programmatically. A convenience macro is defined:
405
406 {\small
407 \begin{verbatim}
408 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

468 Destroys the window safely. Use this function instead of the delete operator, since
469 different window classes can be destroyed differently. Frames and dialogs
470 are not destroyed immediately when this function is called -- they are added
471 to a list of windows to be deleted on idle time, when all the window's events
472 have been processed. This prevents problems with events being sent to non-existent
473 windows.
474

514 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
515 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and

658
659 \func{virtual void}{Fit}{\void}
660
661 Sizes the window so that it fits around its subwindows. This function won't do
662 anything if there are no subwindows and will only really work correctly if
663 sizers are used for the subwindows layout. Also, if the window has exactly one
664 subwindow it is better (faster and the result is more precise as Fit adds some
665 margin to account for fuzziness of its calculations) to call
666
667 \begin{verbatim}
668 window->SetClientSize(child->GetSize());

677
678 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
679 of a window. Mainly useful with scrolled windows to reset scrollbars after
680 sizing changes that do not trigger a size event, and/or scrolled windows without
681 an interior sizer. This function similarly won't do anything if there are no
682 subwindows.
683
684
685 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

687 \func{virtual void}{Freeze}{\void}
688
689 Freezes the window or, in other words, prevents any updates from taking place
690 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
691 be called to reenable window redrawing. Calls to these two functions may be
692 nested.
693
694 This method is useful for visual appearance optimization (for example, it
695 is a good idea to use it before doing many large text insertions in a row into
696 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
697 controls so it is mostly just a hint to wxWidgets and not a mandatory
698 directive.

826
827 Returns a reference to the list of the window's children. \texttt{wxWindowList}

833
834 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
835
836 Returns the default font and colours which are used by the control. This is
837 useful if you want to use the same font or colour in your own control as in a
838 standard control -- which is a much better idea than hard coding specific
839 colours or fonts which might look completely out of place on the users
840 system, especially if it uses themes.
841
842 The \arg{variant} parameter is only relevant under Mac currently and is
843 ignore under other platforms. Under Mac, it will change the size of the
844 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
845 for more about this.
846
847 This static method is ``overridden'' in many derived classes and so calling,
848 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
849 return the values appropriate for a button which will be normally different
850 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
851
852 The \texttt{wxVisualAttributes} structure has at least the fields
853 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
854 if it was not possible to determine the default control appearance or,
855 especially for the background colour, if the field doesn't make sense as is
856 the case for \texttt{colBg} for the controls with themed background.

930 Currently this is the same as calling
931 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
932
933 One advantage of using this function compared to the static version is that
934 the call is automatically dispatched to the correct class (as usual with
935 virtual functions) and you don't have to specify the class name explicitly.
936
937 The other one is that in the future this function could return different
938 results, for example it might return a different font for an ``Ok'' button
939 than for a generic button if the users GUI is configured to show such buttons
940 in bold font. Of course, the down side is that it is impossible to call this
941 function without actually having an object to apply it to whereas the static
942 version can be used without having to create an object first.

1457 This method is mostly used internally by the library itself and you normally

1469 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1470
1471 \func{void}{InheritAttributes}{\void}
1472
1473 This function is (or should be, in case of custom controls) called during
1474 window creation to intelligently set up the window visual attributes, that is
1475 the font and the foreground and background colours.
1476
1477 By ``intelligently'' the following is meant: by default, all windows use their
1478 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1479 if some of the parents attributes are explicitly (that is, using
1480 \helpref{SetFont}{wxwindowsetfont} and not
1481 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1482 corresponding attribute hadn't been explicitly set for this window itself,
1483 then this window takes the same value as used by the parent. In addition, if
1484 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1485 to return \false, the colours will not be changed no matter what and only the
1486 font might.
1487
1488 This rather complicated logic is necessary in order to accommodate the
1489 different usage scenarios. The most common one is when all default attributes
1490 are used and in this case, nothing should be inherited as in modern GUIs
1491 different controls use different fonts (and colours) than their siblings so
1492 they can't inherit the same value from the parent. However it was also deemed
1493 desirable to allow to simply change the attributes of all children at once by
1494 just changing the font or colour of their common parent, hence in this case we
1495 do inherit the parents attributes.

1700
1701 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1702
1703 Moves this window in the tab navigation order after the specified \arg{win}.
1704 This means that when the user presses \texttt{TAB} key on that other window,
1705 the focus switches to this window.
1706
1707 Default tab order is the same as creation order, this function and
1708 \helpref{MoveBeforeInTabOrder()}{wxwindowmovebeforeintaborder} allow to change
1709 it after creating all the windows.
1710

1726 \membersection{wxWindow::Navigate}\label{wxwindownavigate}

1731 a wxNavigationKeyEvent.
1732
1733 \wxheading{Parameters}
1734
1735 \docparam{flags}{A combination of wxNavigationKeyEvent::IsForward and wxNavigationKeyEvent::WinChange.}
1736
1737 \wxheading{Remarks}
1738
1739 You may wish to call this from a text control custom keypress handler to do the default
1740 navigation behaviour for the tab key, since the standard default behaviour for
1741 a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
1742 and not navigate to the next control.

1749 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1750 function allows to retrieve the effective id of the latter control from the id
1751 of the former. This is useful for example to find the control following its
1752 \helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the
1753 label is available to the caller but it is known that the two controls were

2235 This virtual function is normally only used internally, but
2236 sometimes an application may need it to implement functionality
2237 that should not be disabled by an application defining an OnIdle
2238 handler in a derived class.

2278
2279 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2280
2281 Pops up the given menu at the specified coordinates, relative to this
2282 window, and returns control when the user has dismissed the menu. If a
2283 menu item is selected, the corresponding menu event is generated and will be
2284 processed as usually. If the coordinates are not specified, current mouse
2285 cursor position is used.

2306
2307 It is recommended to not explicitly specify coordinates when calling PopupMenu
2308 in response to mouse click, because some of the ports (namely, wxGTK) can do
2309 a better job of positioning the menu in that case.

2328 \membersection{wxWindow::PushEventHandler}\label{wxwindowpusheventhandler}

2335
2336 \docparam{handler}{Specifies the handler to be pushed.}
2337
2338 \wxheading{Remarks}
2339
2340 An event handler is an object that is capable of processing the events
2341 sent to a window. By default, the window is its own event handler, but
2342 an application may wish to substitute another, for example to allow
2343 central implementation of event-handling for a variety of different
2344 window classes.
2345
2346 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2347 an application to set up a chain of event handlers, where an event not handled by one event handler is
2348 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2349 remove the event handler.

2376
2377 Causes this window, and all of its children recursively (except under wxGTK1
2378 where this is not implemented), to be repainted. Note that repainting doesn't
2379 happen immediately but only during the next event loop iteration, if you need

2399
2400 Redraws the contents of the given rectangle: only the area inside it will be
2401 repainted.
2402
2403 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2410 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2411
2412 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2413 will receive a hotkey event. It will receive the event even if the application is in the background
2414 and does not have the input focus because the user is working with some other application.
2415
2416 \wxheading{Parameters}
2417
2418 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2621
2622 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2623 be called automatically when the window is resized. Please note that this only
2624 happens for the windows usually used to contain children, namely
2625 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2626 (and the classes deriving from them).
2627
2628 This method is called implicitly by
2629 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2630 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2631 manually or otherwise the window layout won't be correctly updated when its

2656 \docparam{colour}{The colour to be used as the background colour, pass
2657 {\tt wxNullColour} to reset to the default colour.}
2658
2659 \wxheading{Remarks}
2660
2661 The background colour is usually painted by the default\rtfsp
2662 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2663 under Windows and automatically under GTK.
2664
2665 Note that setting the background colour does not cause an immediate refresh, so you
2666 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2667 calling this function.
2668
2669 Using this function will disable attempts to use themes for this
2670 window, if the system supports them. Use with care since usually the

2690 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2691 application to implement (wxBG\_STYLE\_CUSTOM).
2692
2693 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2694 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2704
2705 \func{void}{SetInitialSize}{\param{const wxSize\& }{size = wxDefaultSize}}
2706
2707 A {\it smart} SetSize that will fill in default size components with the
2708 window's {\it best} size values. Also sets the window's minsize to
2709 the value passed in for use with sizers. This means that if a full or
2710 partial size is passed to this function then the sizers will use that
2711 size instead of the results of GetBestSize to determine the minimum
2712 needs of the window for layout.
2713
2714 Most controls will use this to set their initial size, and their min
2715 size to the passed in value (if any.)

2736 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2737
2738 This sets the size of the window client area in pixels. Using this function to size a window
2739 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2740 worry about what dimensions the border or title bar have when trying to fit the window

2840
2841 \docparam{handler}{Specifies the handler to be set.}
2842
2843 \wxheading{Remarks}
2844
2845 An event handler is an object that is capable of processing the events
2846 sent to a window. By default, the window is its own event handler, but
2847 an application may wish to substitute another, for example to allow
2848 central implementation of event-handling for a variety of different
2849 window classes.
2850
2851 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2852 this sets up a chain of event handlers, where an event not handled by one event handler is
2853 handed to the next one in the chain.

2882 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2916 This function is called by wxWidgets keyboard navigation code when the user
2917 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).

2928 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2929 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2930 explanations.
2931
2932 Please notice that the given font is \emph{not} automatically used for

3130 Let's say you wish to display 50 lines of text, using the same font.
3131 The window is sized so that you can only see 16 lines at a time.
3132
3133 You would use:
3134
3135 {\small%
3136 \begin{verbatim}
3137 SetScrollbar(wxVERTICAL, 0, 16, 50);
3138 \end{verbatim}
3139 }
3140
3141 Note that with the window at this size, the thumb position can never go
3142 above 50 minus 16, or 34.
3143
3144 You can determine how many lines are currently visible by dividing the current view
3145 size by the character height in pixels.
3146
3147 When defining your own scrollbar behaviour, you will always need to recalculate
3148 the scrollbar settings when the window size changes. You could therefore put your
3149 scrollbar calculations and SetScrollbar
3150 call into a function named AdjustScrollbars, which can be called initially and also
3151 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3175
3176 \wxheading{Remarks}
3177
3178 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3179 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3180 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3181 value has to be adjusted when the window is resized, since the page size will have changed.
3182
3183 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3184 the thumb changes size to reflect the page size relative to the length of the document. When the
3185 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3186 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3187 disappear.
3188
3189 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3190 handling of pages and ranges.

3244 \wxheading{Remarks}
3245
3246 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3247 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3248 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3249 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3250 and usually the scrollbar will be automatically hidden.

3351
3352 Sets the window to have the given layout sizer. The window
3353 will then own the object, and will take care of its deletion.
3354 If an existing layout constraints object is already owned by the
3355 window, it will be deleted if the deleteOld parameter is true.
3356
3357 Note that this function will also call
3358 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3359 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3360
3361 \wxheading{Parameters}
3362
3363 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3364 the window's sizer. See below.}

3374 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3375 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3376 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3377 only the sizer will have effect.

3391
3392 This function tells a window if it should use the system's "theme" code
3393 to draw the windows' background instead if its own background drawing
3394 code. This does not always have any effect since the underlying platform
3395 obviously needs to support the notion of themes in user defined windows.
3396 One such platform is GTK+ where windows can have (very colourful) backgrounds
3397 defined by a user's selected theme.
3398
3399 Dialogs, notebook pages and the status bar have this flag set to true
3400 by default so that the default look and feel is simulated best.

3491 This function can be called under all platforms but only does anything under
3492 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3493 exist in several sizes which correspond to the elements of wxWindowVariant

3641
3642 Calling this method immediately repaints the invalidated area of the window and
3643 all of its children recursively while this would usually only happen when the
3644 flow of control returns to the event loop.
3645 Notice that this function doesn't invalidate any area of the window so
3646 nothing happens if nothing has been invalidated (i.e. marked as requiring
3647 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3648 immediately redraw the window unconditionally.

3651 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3652
3653 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3654
3655 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3656 the window. The particular implementation depends on the window; for
3657 example a wxToolBar will send an update UI event for each toolbar button,
3658 and a wxFrame will send an update UI event for each menubar menu item.
3659 You can call this function from your application to ensure that your
3660 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3661 are concerned). This may be necessary if you have called
3662 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3663 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3664 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3665
3666 {\it flags} should be a bitlist of one or more of the following values.
3667
3668 \begin{verbatim}
3669 enum wxUpdateUI
3670 {
3671 wxUPDATE_UI_NONE = 0x0000, // No particular value
3672 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3673 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3674 };
3675 \end{verbatim}
3676
3677 If you are calling this function from an OnInternalIdle or OnIdle
3678 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3679 this tells the window to only update the UI elements that need
3680 to be updated in idle time. Some windows update their elements
3681 only when necessary, for example when a menu is about to be shown.
3682 The following is an example of how to call UpdateWindowUI from
3683 an idle function.
3684
3685 \begin{verbatim}
3686 void MyWindow::OnInternalIdle()
3687 {
3688 if (wxUpdateUIEvent::CanUpdate(this))
