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 only implemented for wxMSW 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}.

291 \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
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}

320 \perlnote{In wxPerl this method returns a 2-element list instead of
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.}

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
681 subwindows.

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
727 specified minimum size. ie. it is the minimum size the window should currently

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

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

1454 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1455
1456 \func{void}{InheritAttributes}{\void}
1457
1458 This function is (or should be, in case of custom controls) called during
1459 window creation to intelligently set up the window visual attributes, that is
1460 the font and the foreground and background colours.
1461
1462 By ``intelligently'' the following is meant: by default, all windows use their
1463 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1464 if some of the parents attributes are explicitly (that is, using
1465 \helpref{SetFont}{wxwindowsetfont} and not
1466 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1467 corresponding attribute hadn't been explicitly set for this window itself,
1468 then this window takes the same value as used by the parent. In addition, if
1469 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1470 to return \false, the colours will not be changed no matter what and only the
1471 font might.
1472
1473 This rather complicated logic is necessary in order to accommodate the
1474 different usage scenarios. The most common one is when all default attributes
1475 are used and in this case, nothing should be inherited as in modern GUIs
1476 different controls use different fonts (and colours) than their siblings so
1477 they can't inherit the same value from the parent. However it was also deemed
1478 desirable to allow to simply change the attributes of all children at once by
1479 just changing the font or colour of their common parent, hence in this case we
1480 do inherit the parents attributes.

2159
2160 \func{virtual void}{OnInternalIdle}{\void}
2161
2162 This virtual function is normally only used internally, but
2163 sometimes an application may need it to implement functionality
2164 that should not be disabled by an application defining an OnIdle
2165 handler in a derived class.
2166
2167 This function may be used to do delayed painting, for example,
2168 and most implementations call \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
2169 in order to send update events to the window in idle time.

2205
2206 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2207
2208 Pops up the given menu at the specified coordinates, relative to this
2209 window, and returns control when the user has dismissed the menu. If a
2210 menu item is selected, the corresponding menu event is generated and will be
2211 processed as usually. If the coordinates are not specified, current mouse
2212 cursor position is used.

2231 is called to ensure that the menu items are in the correct state. The menu does
2232 not get deleted by the window.
2233
2234 It is recommended to not explicitly specify coordinates when calling PopupMenu
2235 in response to mouse click, because some of the ports (namely, wxGTK) can do
2236 a better job of positioning the menu in that case.

2253 \wxheading{Parameters}
2254
2255 \docparam{handler}{Specifies the handler to be pushed.}
2256
2257 \wxheading{Remarks}
2258
2259 An event handler is an object that is capable of processing the events
2260 sent to a window. By default, the window is its own event handler, but
2261 an application may wish to substitute another, for example to allow
2262 central implementation of event-handling for a variety of different
2263 window classes.
2264
2265 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2266 an application to set up a chain of event handlers, where an event not handled by one event handler is
2267 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2268 remove the event handler.

2294 \func{virtual void}{Refresh}{\param{bool}{ eraseBackground = {\tt true}}, \param{const wxRect* }{rect = NULL}}
2295
2296 Causes this window, and all of its children recursively (except under wxGTK1
2297 where this is not implemented), to be repainted. Note that repainting doesn't
2298 happen immediately but only during the next event loop iteration, if you need

2318
2319 Redraws the contents of the given rectangle: only the area inside it will be
2320 repainted.
2321
2322 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2329 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2330
2331 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2332 will receive a hotkey event. It will receive the event even if the application is in the background
2333 and does not have the input focus because the user is working with some other application.
2334
2335 \wxheading{Parameters}
2336
2337 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If
2338 this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF.
2339 This is a MSW specific detail.}

2540
2541 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2542 be called automatically when the window is resized. Please note that this only
2543 happens for the windows usually used to contain children, namely
2544 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2545 (and the classes deriving from them).
2546
2547 This method is called implicitly by
2548 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2549 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2550 manually or otherwise the window layout won't be correctly updated when its
2551 size changes.
2552

2569 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2570 explanation of the difference between this method and
2571 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2572
2573 \wxheading{Parameters}
2574
2575 \docparam{colour}{The colour to be used as the background colour, pass
2576 {\tt wxNullColour} to reset to the default colour.}
2577
2578 \wxheading{Remarks}
2579
2580 The background colour is usually painted by the default\rtfsp
2581 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2582 under Windows and automatically under GTK.
2583
2584 Note that setting the background colour does not cause an immediate refresh, so you
2585 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2586 calling this function.
2587
2588 Using this function will disable attempts to use themes for this
2589 window, if the system supports them. Use with care since usually the
2590 themes represent the appearance chosen by the user to be used for all
2591 applications on the system.

2608 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2609 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2610 application to implement (wxBG\_STYLE\_CUSTOM).
2611
2612 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2625
2626 A {\it smart} SetSize that will fill in default size components with the

2654 This sets the size of the window client area in pixels. Using this function to size a window
2655 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2656 worry about what dimensions the border or title bar have when trying to fit the window

2680 Sets the window to have the given layout constraints. The window
2681 will then own the object, and will take care of its deletion.
2682 If an existing layout constraints object is already owned by the
2683 window, it will be deleted.
2684
2685 \wxheading{Parameters}

2691
2692 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2693 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2694 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2695 sizer will have effect.

2701 This normally does not need to be called by user code. It is called

2756
2757 \docparam{handler}{Specifies the handler to be set.}
2758
2759 \wxheading{Remarks}
2760
2761 An event handler is an object that is capable of processing the events
2762 sent to a window. By default, the window is its own event handler, but
2763 an application may wish to substitute another, for example to allow
2764 central implementation of event-handling for a variety of different
2765 window classes.
2766
2767 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2768 this sets up a chain of event handlers, where an event not handled by one event handler is
2769 handed to the next one in the chain.

2793 events are propagated upwards to the window parent recursively until a handler
2794 for them is found. Using this style allows to prevent them from being
2795 propagated beyond this window. Notice that wxDialog has this style on by
2796 default for the reasons explained in the

2798 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2799 window from being used as an implicit parent for the dialogs which were

2831
2832 This function is called by wxWidgets keyboard navigation code when the user
2833 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2834 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2844 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2845 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2846 explanations.
2847
2848 Please notice that the given font is \emph{not} automatically used for
2849 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2850 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3046 Let's say you wish to display 50 lines of text, using the same font.
3047 The window is sized so that you can only see 16 lines at a time.
3048
3049 You would use:
3050
3051 {\small%
3052 \begin{verbatim}
3053 SetScrollbar(wxVERTICAL, 0, 16, 50);
3054 \end{verbatim}
3055 }
3056
3057 Note that with the window at this size, the thumb position can never go
3058 above 50 minus 16, or 34.
3059
3060 You can determine how many lines are currently visible by dividing the current view
3061 size by the character height in pixels.
3062
3063 When defining your own scrollbar behaviour, you will always need to recalculate
3064 the scrollbar settings when the window size changes. You could therefore put your
3065 scrollbar calculations and SetScrollbar
3066 call into a function named AdjustScrollbars, which can be called initially and also
3067 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3092 \wxheading{Remarks}
3093
3094 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3095 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3096 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3097 value has to be adjusted when the window is resized, since the page size will have changed.
3098
3099 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3100 the thumb changes size to reflect the page size relative to the length of the document. When the
3101 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3102 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3103 disappear.
3104
3105 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3106 handling of pages and ranges.

3161
3162 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3163 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3164 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3165 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3166 and usually the scrollbar will be automatically hidden.

3210
3211 \docparam{sizeFlags}{Indicates the interpretation of other parameters. It is a bit list of the following:
3212
3213 {\bf wxSIZE\_AUTO\_WIDTH}: a $wxDefaultCoord$ width value is taken to indicate
3214 a wxWidgets-supplied default width.\\
3215 {\bf wxSIZE\_AUTO\_HEIGHT}: a $wxDefaultCoord$ height value is taken to indicate
3216 a wxWidgets-supplied default height.\\
3217 {\bf wxSIZE\_AUTO}: $wxDefaultCoord$ size values are taken to indicate

3221 {\bf wxSIZE\_ALLOW\_MINUS\_ONE}: allow negative dimensions (ie. value of $wxDefaultCoord$) to be interpreted
3222 as real dimensions, not default values.
3223 {\bf wxSIZE\_FORCE}: normally, if the position and the size of the window are
3224 already the same as the parameters of this function, nothing is done. but with

3295
3296 Sets the window to have the given layout sizer. The window
3297 will then own the object, and will take care of its deletion.
3298 If an existing layout constraints object is already owned by the
3299 window, it will be deleted if the deleteOld parameter is true.
3300
3301 Note that this function will also call
3302 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3303 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3304
3305 \wxheading{Parameters}
3306
3307 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3308 the window's sizer. See below.}
3309
3310 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3311 Pass false if you wish to handle deleting the old sizer yourself.}

3314
3315 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3316 the following applied:
3317
3318 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3319 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3320 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3321 only the sizer will have effect.

3335
3336 This function tells a window if it should use the system's "theme" code
3337 to draw the windows' background instead if its own background drawing
3338 code. This does not always have any effect since the underlying platform
3339 obviously needs to support the notion of themes in user defined windows.
3340 One such platform is GTK+ where windows can have (very colourful) backgrounds
3341 defined by a user's selected theme.
3342
3343 Dialogs, notebook pages and the status bar have this flag set to true
3344 by default so that the default look and feel is simulated best.

3433
3434 This function can be called under all platforms but only does anything under
3435 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3436 exist in several sizes which correspond to the elements of wxWindowVariant
3437 enum:
3438 \begin{verbatim}
3439 enum wxWindowVariant
3440 {
3441 wxWINDOW_VARIANT_NORMAL, // Normal size
3442 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3443 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3444 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3445 };

3560
3561 \func{virtual void}{Update}{\void}
3562
3563 Calling this method immediately repaints the invalidated area of the window and
3564 all of its children recursively while this would usually only happen when the
3565 flow of control returns to the event loop. Notice that this function doesn't
3566 refresh the window and does nothing if the window hadn't been already
3567 repainted. Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3568 immediately redraw the window unconditionally.

3571 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3572
3573 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3574
3575 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3576 the window. The particular implementation depends on the window; for
3577 example a wxToolBar will send an update UI event for each toolbar button,
3578 and a wxFrame will send an update UI event for each menubar menu item.
3579 You can call this function from your application to ensure that your
3580 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3581 are concerned). This may be necessary if you have called
3582 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3583 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3584 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3585
3586 {\it flags} should be a bitlist of one or more of the following values.
3587
3588 \begin{verbatim}
3589 enum wxUpdateUI
3590 {
3591 wxUPDATE_UI_NONE = 0x0000, // No particular value
3592 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3593 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3594 };
3595 \end{verbatim}
3596
3597 If you are calling this function from an OnInternalIdle or OnIdle
3598 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3599 this tells the window to only update the UI elements that need
3600 to be updated in idle time. Some windows update their elements
3601 only when necessary, for example when a menu is about to be shown.
3602 The following is an example of how to call UpdateWindowUI from
3603 an idle function.
3604
3605 \begin{verbatim}
3606 void MyWindow::OnInternalIdle()
3607 {
3608 if (wxUpdateUIEvent::CanUpdate(this))
3609 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
