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.}

123 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
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.

171
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.

215 \func{void}{Center}{\param{int}{ direction}}
216
217 A synonym for \helpref{Centre}{wxwindowcentre}.
218
219
220 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}

225
226
227 \membersection{wxWindow::CenterOnScreen}\label{wxwindowcenteronscreen}
228
229 \func{void}{CenterOnScreen}{\param{int}{ direction}}
230
231 A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}.
232
233
234 \membersection{wxWindow::Centre}\label{wxwindowcentre}
235
236 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
237
238 Centres the window.
239
240 \wxheading{Parameters}
241
242 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
243 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
244 if you want to center the window on the entire screen and not on its
245 parent window.}
246
247 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
248 (it has no effect).
249
250 \wxheading{Remarks}
251
252 If the window is a top level one (i.e. doesn't have a parent), it will be
253 centered relative to the screen anyhow.

260 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
261
262 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
263
264 Centres the window on its parent. This is a more readable synonym for
265 \helpref{Centre}{wxwindowcentre}.
266
267 \wxheading{Parameters}
268
269 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
270 or {\tt wxBOTH}.}
271
272 \wxheading{Remarks}
273
274 This methods provides for a way to center top level windows over their
275 parents instead of the entire screen. If there is no parent or if the
276 window is not a top level window, then behaviour is the same as
277 \helpref{wxWindow::Centre}{wxwindowcentre}.

285
286 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
287
288 Centres the window on screen. This only works for top level windows -
289 otherwise, the window will still be centered on its parent.
290
291 \wxheading{Parameters}
292
293 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

306 cause an erase background event to be generated.
307
308
309 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}

314 modifying its parameters.}
315
316 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
317
318 Converts to screen coordinates from coordinates relative to this window.
319
320 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
321 a screen coordinate will be passed out.}
322
323 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
324 a screen coordinate will be passed out.}
325
326 \docparam{pt}{The client position for the second form of the function.}
327
328 \pythonnote{In place of a single overloaded method name, wxPython
329 implements the following methods:\par
330 \indented{2cm}{\begin{twocollist}

335
336
337 \membersection{wxWindow::Close}\label{wxwindowclose}
338
339 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
340
341 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
342 handler usually tries to close the window. It doesn't close the window itself,
343 however.
344
345 \wxheading{Parameters}
346
347 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
348 of this window, {\tt true} if it cannot.}
349
350 \wxheading{Remarks}
351
352 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
353 an opportunity for the window to choose whether to destroy the window.
354 Usually it is only used with the top level windows (wxFrame and wxDialog
355 classes) as the others are not supposed to have any special OnClose() logic.
356
357 The close handler should check whether the window is being deleted forcibly,
358 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
359 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
360
361 {\it Note} that calling Close does not guarantee that the window will be
362 destroyed; but it provides a way to simulate a manual close of a window, which
363 may or may not be implemented by destroying the window. The default
364 implementation of wxDialog::OnCloseWindow does not necessarily delete the
365 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
366 the appropriate button event handler and may do anything at all.
367
368 To guarantee that the window will be destroyed, call
369 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

379
380 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
381
382 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
383
384 Converts a point or size from dialog units to pixels.
385
386 For the x dimension, the dialog units are multiplied by the average character width
387 and then divided by 4.
388
389 For the y dimension, the dialog units are multiplied by the average character height
390 and then divided by 8.
391
392 \wxheading{Remarks}
393
394 Dialog units are used for maintaining a dialog's proportions even if the font changes.
395
396 You can also use these functions programmatically. A convenience macro is defined:
397
398 {\small
399 \begin{verbatim}
400 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

459
460 Destroys the window safely. Use this function instead of the delete operator, since
461 different window classes can be destroyed differently. Frames and dialogs
462 are not destroyed immediately when this function is called -- they are added
463 to a list of windows to be deleted on idle time, when all the window's events
464 have been processed. This prevents problems with events being sent to non-existent
465 windows.
466
467 \wxheading{Return value}

502
503 \func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}
504
505 Does the window-specific updating after processing the update event.
506 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
507 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
508 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
509 implements this function as follows:

652
653 Sizes the window so that it fits around its subwindows. This function won't do
654 anything if there are no subwindows and will only really work correctly if the
655 sizers are used for the subwindows layout. Also, if the window has exactly one
656 subwindow it is better (faster and the result is more precise as Fit adds some
657 margin to account for fuzziness of its calculations) to call
658
659 \begin{verbatim}

671 of a window. Mainly useful with scrolled windows to reset scrollbars after
672 sizing changes that do not trigger a size event, and/or scrolled windows without
673 an interior sizer. This function similarly won't do anything if there are no
674 subwindows.
675
676
677 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

680
681 Freezes the window or, in other words, prevents any updates from taking place
682 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
683 be called to reenable window redrawing. Calls to these two functions may be
684 nested.
685
686 This method is useful for visual appearance optimization (for example, it
687 is a good idea to use it before doing many large text insertions in a row into
688 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
689 controls so it is mostly just a hint to wxWidgets and not a mandatory

716
717 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
718 in one thing. GetBestSize should return the minimum untruncated size of the
719 window, while this method will return the largest of BestSize and any user
720 specified minimum size. ie. it is the minimum size the window should currently

742 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
743 application to implement (wxBG\_STYLE\_CUSTOM).
744
745 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

773 control label is not truncated. For windows containing subwindows (typically

819
820 Returns a reference to the list of the window's children. \texttt{wxWindowList}

827 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
828
829 Returns the default font and colours which are used by the control. This is
830 useful if you want to use the same font or colour in your own control as in a
831 standard control -- which is a much better idea than hard coding specific
832 colours or fonts which might look completely out of place on the users
833 system, especially if it uses themes.
834
835 The \arg{variant} parameter is only relevant under Mac currently and is
836 ignore under other platforms. Under Mac, it will change the size of the
837 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
838 for more about this.
839
840 This static method is ``overridden'' in many derived classes and so calling,
841 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
842 return the values appropriate for a button which will be normally different
843 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
844
845 The \texttt{wxVisualAttributes} structure has at least the fields
846 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
847 if it was not possible to determine the default control appearance or,
848 especially for the background colour, if the field doesn't make sense as is
849 the case for \texttt{colBg} for the controls with themed background.

920 Currently this is the same as calling
921 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
922
923 One advantage of using this function compared to the static version is that
924 the call is automatically dispatched to the correct class (as usual with
925 virtual functions) and you don't have to specify the class name explicitly.
926
927 The other one is that in the future this function could return different
928 results, for example it might return a different font for an ``Ok'' button
929 than for a generic button if the users GUI is configured to show such buttons
930 in bold font. Of course, the down side is that it is impossible to call this
931 function without actually having an object to apply it to whereas the static
932 version can be used without having to create an object first.

1416 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1417
1418 \func{void}{InheritAttributes}{\void}
1419
1420 This function is (or should be, in case of custom controls) called during
1421 window creation to intelligently set up the window visual attributes, that is
1422 the font and the foreground and background colours.
1423
1424 By ``intelligently'' the following is meant: by default, all windows use their
1425 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1426 if some of the parents attributes are explicitly (that is, using
1427 \helpref{SetFont}{wxwindowsetfont} and not
1428 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1429 corresponding attribute hadn't been explicitly set for this window itself,
1430 then this window takes the same value as used by the parent. In addition, if
1431 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1432 to return \false, the colours will not be changed no matter what and only the
1433 font might.
1434
1435 This rather complicated logic is necessary in order to accommodate the
1436 different usage scenarios. The most common one is when all default attributes
1437 are used and in this case, nothing should be inherited as in modern GUIs
1438 different controls use different fonts (and colours) than their siblings so
1439 they can't inherit the same value from the parent. However it was also deemed
1440 desirable to allow to simply change the attributes of all children at once by
1441 just changing the font or colour of their common parent, hence in this case we
1442 do inherit the parents attributes.

2167
2168 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2169
2170 Pops up the given menu at the specified coordinates, relative to this
2171 window, and returns control when the user has dismissed the menu. If a
2172 menu item is selected, the corresponding menu event is generated and will be
2173 processed as usually. If the coordinates are not specified, current mouse
2174 cursor position is used.

2193 is called to ensure that the menu items are in the correct state. The menu does
2194 not get deleted by the window.
2195
2196 It is recommended to not explicitly specify coordinates when calling PopupMenu
2197 in response to mouse click, because some of the ports (namely, wxGTK) can do
2198 a better job of positioning the menu in that case.

2215 \wxheading{Parameters}
2216
2217 \docparam{handler}{Specifies the handler to be pushed.}
2218
2219 \wxheading{Remarks}
2220
2221 An event handler is an object that is capable of processing the events
2222 sent to a window. By default, the window is its own event handler, but
2223 an application may wish to substitute another, for example to allow
2224 central implementation of event-handling for a variety of different
2225 window classes.
2226
2227 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2228 an application to set up a chain of event handlers, where an event not handled by one event handler is
2229 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2230 remove the event handler.

2256 \func{virtual void}{Refresh}{\param{bool}{ eraseBackground = {\tt true}}, \param{const wxRect* }{rect = NULL}}
2257
2258 Causes this window, and all of its children recursively (except under wxGTK1
2259 where this is not implemented), to be repainted. Note that repainting doesn't
2260 happen immediately but only during the next event loop iteration, if you need

2283
2284 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2293 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2294 will receive a hotkey event. It will receive the event even if the application is in the background
2295 and does not have the input focus because the user is working with some other application.
2296
2297 \wxheading{Parameters}
2298
2299 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2501
2502 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2503 be called automatically when the window is resized. Please note that this only
2504 happens for the windows usually used to contain children, namely
2505 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2506 (and the classes deriving from them).
2507
2508 This method is called implicitly by
2509 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2510 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2511 manually or otherwise the window layout won't be correctly updated when its
2512 size changes.
2513

2530 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2531 explanation of the difference between this method and
2532 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2533
2534 \wxheading{Parameters}
2535
2536 \docparam{colour}{The colour to be used as the background colour, pass
2537 {\tt wxNullColour} to reset to the default colour.}
2538
2539 \wxheading{Remarks}
2540
2541 The background colour is usually painted by the default\rtfsp
2542 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2543 under Windows and automatically under GTK.
2544
2545 Note that setting the background colour does not cause an immediate refresh, so you
2546 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2547 calling this function.
2548
2549 Using this function will disable attempts to use themes for this
2550 window, if the system supports them. Use with care since usually the
2551 themes represent the appearance chosen by the user to be used for all
2552 applications on the system.

2569 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2570 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2571 application to implement (wxBG\_STYLE\_CUSTOM).
2572
2573 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2614
2615 This sets the size of the window client area in pixels. Using this function to size a window
2616 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2617 worry about what dimensions the border or title bar have when trying to fit the window

2718 \docparam{handler}{Specifies the handler to be set.}
2719
2720 \wxheading{Remarks}
2721
2722 An event handler is an object that is capable of processing the events
2723 sent to a window. By default, the window is its own event handler, but
2724 an application may wish to substitute another, for example to allow
2725 central implementation of event-handling for a variety of different
2726 window classes.
2727
2728 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2729 this sets up a chain of event handlers, where an event not handled by one event handler is
2730 handed to the next one in the chain.

2753 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2754 events are propagated upwards to the window parent recursively until a handler

2756 propagated beyond this window. Notice that wxDialog has this style on by
2757 default for the reasons explained in the
2758 \helpref{event processing overview}{eventprocessing}.}
2759 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2760 window from being used as an implicit parent for the dialogs which were
2761 created without a parent. It is useful for the windows which can disappear at

2767 you should use the style of
2768 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2794
2795 This function is called by wxWidgets keyboard navigation code when the user
2796 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2797 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2807 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2808 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2809 explanations.
2810
2811 Please notice that the given font is \emph{not} automatically used for
2812 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2813 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3008
3009 Let's say you wish to display 50 lines of text, using the same font.
3010 The window is sized so that you can only see 16 lines at a time.
3011
3012 You would use:
3013
3014 {\small%
3015 \begin{verbatim}
3016 SetScrollbar(wxVERTICAL, 0, 16, 50);
3017 \end{verbatim}
3018 }
3019
3020 Note that with the window at this size, the thumb position can never go
3021 above 50 minus 16, or 34.
3022
3023 You can determine how many lines are currently visible by dividing the current view
3024 size by the character height in pixels.
3025
3026 When defining your own scrollbar behaviour, you will always need to recalculate
3027 the scrollbar settings when the window size changes. You could therefore put your
3028 scrollbar calculations and SetScrollbar
3029 call into a function named AdjustScrollbars, which can be called initially and also
3030 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3055 \wxheading{Remarks}
3056
3057 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3058 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3059 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3060 value has to be adjusted when the window is resized, since the page size will have changed.
3061
3062 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3063 the thumb changes size to reflect the page size relative to the length of the document. When the
3064 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3065 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3066 disappear.
3067
3068 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3069 handling of pages and ranges.

3124
3125 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3126 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3127 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3128 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3129 and usually the scrollbar will be automatically hidden.

3256
3257 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3258
3259 Sets the window to have the given layout sizer. The window
3260 will then own the object, and will take care of its deletion.
3261 If an existing layout constraints object is already owned by the
3262 window, it will be deleted if the deleteOld parameter is true.
3263
3264 Note that this function will also call
3265 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3266 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3267
3268 \wxheading{Parameters}
3269
3270 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3271 the window's sizer. See below.}
3272
3273 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3274 Pass false if you wish to handle deleting the old sizer yourself.}
3275
3276 \wxheading{Remarks}
3277
3278 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3279 the following applied:
3280
3281 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3282 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3283 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3284 only the sizer will have effect.

3298
3299 This function tells a window if it should use the system's "theme" code
3300 to draw the windows' background instead if its own background drawing
3301 code. This does not always have any effect since the underlying platform
3302 obviously needs to support the notion of themes in user defined windows.
3303 One such platform is GTK+ where windows can have (very colourful) backgrounds
3304 defined by a user's selected theme.
3305
3306 Dialogs, notebook pages and the status bar have this flag set to true
3307 by default so that the default look and feel is simulated best.

3396
3397 This function can be called under all platforms but only does anything under
3398 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3399 exist in several sizes which correspond to the elements of wxWindowVariant
3400 enum:
3401 \begin{verbatim}
3402 enum wxWindowVariant
3403 {
3404 wxWINDOW_VARIANT_NORMAL, // Normal size
3405 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3406 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3407 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3408 };

3523
3524 \func{virtual void}{Update}{\void}
3525
3526 Calling this method immediately repaints the invalidated area of the window and
3527 all of its children recursively while this would usually only happen when the
3528 flow of control returns to the event loop. Notice that this function doesn't
3529 refresh the window and does nothing if the window hadn't been already
3530 repainted. Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3531 immediately redraw the window unconditionally.

3534 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3535
3536 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3537
3538 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3539 the window. The particular implementation depends on the window; for
3540 example a wxToolBar will send an update UI event for each toolbar button,
3541 and a wxFrame will send an update UI event for each menubar menu item.
3542 You can call this function from your application to ensure that your
3543 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3544 are concerned). This may be necessary if you have called
3545 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3546 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3547 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3548
3549 {\it flags} should be a bitlist of one or more of the following values.
3550
3551 \begin{verbatim}
3552 enum wxUpdateUI
3553 {
3554 wxUPDATE_UI_NONE = 0x0000, // No particular value
3555 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3556 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3557 };
3558 \end{verbatim}
3559
3560 If you are calling this function from an OnInternalIdle or OnIdle
3561 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3562 this tells the window to only update the UI elements that need
3563 to be updated in idle time. Some windows update their elements
3564 only when necessary, for example when a menu is about to be shown.
3565 The following is an example of how to call UpdateWindowUI from
3566 an idle function.
3567
3568 \begin{verbatim}
3569 void MyWindow::OnInternalIdle()
3570 {
3571 if (wxUpdateUIEvent::CanUpdate(this))
3572 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
