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

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

239
240
241 \membersection{wxWindow::Centre}\label{wxwindowcentre}
242
243 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
244
245 Centres the window.
246
247 \wxheading{Parameters}
248
249 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
250 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
251 if you want to center the window on the entire screen and not on its
252 parent window.}
253
254 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
255 (it has no effect).
256
257 \wxheading{Remarks}
258
259 If the window is a top level one (i.e. doesn't have a parent), it will be
260 centered relative to the screen anyhow.

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

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

313 cause an erase background event to be generated.
314
315
316 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}

321 modifying its parameters.}
322
323 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
324
325 Converts to screen coordinates from coordinates relative to this window.
326
327 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
328 a screen coordinate will be passed out.}
329
330 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
331 a screen coordinate will be passed out.}
332
333 \docparam{pt}{The client position for the second form of the function.}
334
335 \pythonnote{In place of a single overloaded method name, wxPython
336 implements the following methods:\par
337 \indented{2cm}{\begin{twocollist}

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

386
387 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
388
389 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
390
391 Converts a point or size from dialog units to pixels.
392
393 For the x dimension, the dialog units are multiplied by the average character width
394 and then divided by 4.
395
396 For the y dimension, the dialog units are multiplied by the average character height
397 and then divided by 8.
398
399 \wxheading{Remarks}
400
401 Dialog units are used for maintaining a dialog's proportions even if the font changes.
402
403 You can also use these functions programmatically. A convenience macro is defined:
404
405 {\small
406 \begin{verbatim}
407 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

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

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

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

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

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

723
724 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
725 in one thing. GetBestSize should return the minimum untruncated size of the
726 window, while this method will return the largest of BestSize and any user

750 application to implement (wxBG\_STYLE\_CUSTOM).
751

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

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

1457 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1458
1459 \func{void}{InheritAttributes}{\void}
1460
1461 This function is (or should be, in case of custom controls) called during
1462 window creation to intelligently set up the window visual attributes, that is
1463 the font and the foreground and background colours.
1464
1465 By ``intelligently'' the following is meant: by default, all windows use their
1466 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1467 if some of the parents attributes are explicitly (that is, using
1468 \helpref{SetFont}{wxwindowsetfont} and not
1469 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1470 corresponding attribute hadn't been explicitly set for this window itself,
1471 then this window takes the same value as used by the parent. In addition, if
1472 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1473 to return \false, the colours will not be changed no matter what and only the
1474 font might.
1475
1476 This rather complicated logic is necessary in order to accommodate the
1477 different usage scenarios. The most common one is when all default attributes
1478 are used and in this case, nothing should be inherited as in modern GUIs
1479 different controls use different fonts (and colours) than their siblings so
1480 they can't inherit the same value from the parent. However it was also deemed
1481 desirable to allow to simply change the attributes of all children at once by
1482 just changing the font or colour of their common parent, hence in this case we
1483 do inherit the parents attributes.

1688
1689 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1690
1691 Moves this window in the tab navigation order after the specified \arg{win}.
1692 This means that when the user presses \texttt{TAB} key on that other window,
1693 the focus switches to this window.
1694
1695 Default tab order is the same as creation order, this function and

1722
1723 \docparam{flags}{A combination of wxNavigationKeyEvent::IsForward and wxNavigationKeyEvent::WinChange.}

1727 You may wish to call this from a text control custom keypress handler to do the default
1728 navigation behaviour for the tab key, since the standard default behaviour for
1729 a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
1730 and not navigate to the next control.

2204 \func{virtual void}{OnInternalIdle}{\void}
2205
2206 This virtual function is normally only used internally, but
2207 sometimes an application may need it to implement functionality
2208 that should not be disabled by an application defining an OnIdle
2209 handler in a derived class.
2210
2211 This function may be used to do delayed painting, for example,
2212 and most implementations call \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}

2249
2250 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2251
2252 Pops up the given menu at the specified coordinates, relative to this
2253 window, and returns control when the user has dismissed the menu. If a
2254 menu item is selected, the corresponding menu event is generated and will be
2255 processed as usually. If the coordinates are not specified, current mouse
2256 cursor position is used.

2275 is called to ensure that the menu items are in the correct state. The menu does
2276 not get deleted by the window.
2277
2278 It is recommended to not explicitly specify coordinates when calling PopupMenu
2279 in response to mouse click, because some of the ports (namely, wxGTK) can do
2280 a better job of positioning the menu in that case.

2297 \wxheading{Parameters}
2298
2299 \docparam{handler}{Specifies the handler to be pushed.}
2300
2301 \wxheading{Remarks}
2302
2303 An event handler is an object that is capable of processing the events
2304 sent to a window. By default, the window is its own event handler, but
2305 an application may wish to substitute another, for example to allow
2306 central implementation of event-handling for a variety of different
2307 window classes.
2308
2309 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2310 an application to set up a chain of event handlers, where an event not handled by one event handler is
2311 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2312 remove the event handler.

2339
2340 Causes this window, and all of its children recursively (except under wxGTK1
2341 where this is not implemented), to be repainted. Note that repainting doesn't
2342 happen immediately but only during the next event loop iteration, if you need

2363 Redraws the contents of the given rectangle: only the area inside it will be
2364 repainted.
2365
2366 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2375 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2376 will receive a hotkey event. It will receive the event even if the application is in the background
2377 and does not have the input focus because the user is working with some other application.

2379 \wxheading{Parameters}
2380
2381 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2584
2585 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2586 be called automatically when the window is resized. Please note that this only
2587 happens for the windows usually used to contain children, namely
2588 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2589 (and the classes deriving from them).
2590
2591 This method is called implicitly by
2592 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2593 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2594 manually or otherwise the window layout won't be correctly updated when its
2595 size changes.
2596

2617 \wxheading{Parameters}
2618
2619 \docparam{colour}{The colour to be used as the background colour, pass
2620 {\tt wxNullColour} to reset to the default colour.}
2621
2622 \wxheading{Remarks}
2623
2624 The background colour is usually painted by the default\rtfsp
2625 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2626 under Windows and automatically under GTK.
2627
2628 Note that setting the background colour does not cause an immediate refresh, so you
2629 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2630 calling this function.
2631
2632 Using this function will disable attempts to use themes for this
2633 window, if the system supports them. Use with care since usually the
2634 themes represent the appearance chosen by the user to be used for all
2635 applications on the system.

2652 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2653 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2654 application to implement (wxBG\_STYLE\_CUSTOM).
2655
2656 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2674 size instead of the results of GetBestSize to determine the minimum
2675 needs of the window for layout.

2698
2699 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2700
2701 This sets the size of the window client area in pixels. Using this function to size a window
2702 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2703 worry about what dimensions the border or title bar have when trying to fit the window

2726
2727 Sets the window to have the given layout constraints. The window
2728 will then own the object, and will take care of its deletion.
2729 If an existing layout constraints object is already owned by the
2730 window, it will be deleted.

2738
2739 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2740 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2741 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2803
2804 \docparam{handler}{Specifies the handler to be set.}
2805
2806 \wxheading{Remarks}
2807
2808 An event handler is an object that is capable of processing the events
2809 sent to a window. By default, the window is its own event handler, but
2810 an application may wish to substitute another, for example to allow
2811 central implementation of event-handling for a variety of different
2812 window classes.
2813
2814 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2815 this sets up a chain of event handlers, where an event not handled by one event handler is
2816 handed to the next one in the chain.

2841 for them is found. Using this style allows to prevent them from being
2842 propagated beyond this window. Notice that wxDialog has this style on by
2843 default for the reasons explained in the

2845 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2846 window from being used as an implicit parent for the dialogs which were
2847 created without a parent. It is useful for the windows which can disappear at

2853 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so

2878
2879 This function is called by wxWidgets keyboard navigation code when the user
2880 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).

2890 parent window if you don't want its font to be inherited by its children,
2891 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2892 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2893 explanations.
2894
2895 Please notice that the given font is \emph{not} automatically used for
2896 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2897 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3093 Let's say you wish to display 50 lines of text, using the same font.
3094 The window is sized so that you can only see 16 lines at a time.
3095
3096 You would use:
3097
3098 {\small%
3099 \begin{verbatim}
3100 SetScrollbar(wxVERTICAL, 0, 16, 50);
3101 \end{verbatim}
3102 }
3103
3104 Note that with the window at this size, the thumb position can never go
3105 above 50 minus 16, or 34.
3106
3107 You can determine how many lines are currently visible by dividing the current view
3108 size by the character height in pixels.
3109
3110 When defining your own scrollbar behaviour, you will always need to recalculate
3111 the scrollbar settings when the window size changes. You could therefore put your
3112 scrollbar calculations and SetScrollbar
3113 call into a function named AdjustScrollbars, which can be called initially and also
3114 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3138
3139 \wxheading{Remarks}
3140
3141 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3142 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3143 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3144 value has to be adjusted when the window is resized, since the page size will have changed.
3145
3146 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3147 the thumb changes size to reflect the page size relative to the length of the document. When the
3148 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3149 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3150 disappear.
3151
3152 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3153 handling of pages and ranges.

3208
3209 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3210 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3211 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3212 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3213 and usually the scrollbar will be automatically hidden.

3309
3310 Sets the window to have the given layout sizer. The window
3311 will then own the object, and will take care of its deletion.
3312 If an existing layout constraints object is already owned by the
3313 window, it will be deleted if the deleteOld parameter is true.
3314
3315 Note that this function will also call
3316 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3317 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3318
3319 \wxheading{Parameters}
3320
3321 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3322 the window's sizer. See below.}

3331
3332 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3333 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3334 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3335 only the sizer will have effect.

3349
3350 This function tells a window if it should use the system's "theme" code
3351 to draw the windows' background instead if its own background drawing
3352 code. This does not always have any effect since the underlying platform
3353 obviously needs to support the notion of themes in user defined windows.
3354 One such platform is GTK+ where windows can have (very colourful) backgrounds
3355 defined by a user's selected theme.
3356
3357 Dialogs, notebook pages and the status bar have this flag set to true
3358 by default so that the default look and feel is simulated best.

3447
3448 This function can be called under all platforms but only does anything under
3449 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3450 exist in several sizes which correspond to the elements of wxWindowVariant
3451 enum:
3452 \begin{verbatim}
3453 enum wxWindowVariant

3576
3577 Calling this method immediately repaints the invalidated area of the window and
3578 all of its children recursively while this would usually only happen when the
3579 flow of control returns to the event loop.
3580 Notice that this function doesn't invalidate any area of the window so
3581 nothing happens if nothing has been invalidated (i.e. marked as requiring
3582 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3583 immediately redraw the window unconditionally.

3586 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3587
3588 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3589
3590 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3591 the window. The particular implementation depends on the window; for
3592 example a wxToolBar will send an update UI event for each toolbar button,
3593 and a wxFrame will send an update UI event for each menubar menu item.
3594 You can call this function from your application to ensure that your
3595 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3596 are concerned). This may be necessary if you have called
3597 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3598 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3599 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3600
3601 {\it flags} should be a bitlist of one or more of the following values.
3602
3603 \begin{verbatim}
3604 enum wxUpdateUI
3605 {
3606 wxUPDATE_UI_NONE = 0x0000, // No particular value
3607 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3608 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3609 };
3610 \end{verbatim}
3611
3612 If you are calling this function from an OnInternalIdle or OnIdle
3613 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3614 this tells the window to only update the UI elements that need
3615 to be updated in idle time. Some windows update their elements
3616 only when necessary, for example when a menu is about to be shown.
3617 The following is an example of how to call UpdateWindowUI from
3618 an idle function.
3619
3620 \begin{verbatim}
3621 void MyWindow::OnInternalIdle()
3622 {
3623 if (wxUpdateUIEvent::CanUpdate(this))
