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

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

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

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

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

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

238
239 A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}.
240
241
242 \membersection{wxWindow::Centre}\label{wxwindowcentre}
243
244 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
245
246 Centres the window.
247
248 \wxheading{Parameters}
249
250 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
251 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
252 if you want to center the window on the entire screen and not on its
253 parent window.}
254
255 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
256 (it has no effect).
257
258 \wxheading{Remarks}
259
260 If the window is a top level one (i.e. doesn't have a parent), it will be
261 centered relative to the screen anyhow.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

1458 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1459
1460 \func{void}{InheritAttributes}{\void}
1461
1462 This function is (or should be, in case of custom controls) called during
1463 window creation to intelligently set up the window visual attributes, that is
1464 the font and the foreground and background colours.
1465
1466 By ``intelligently'' the following is meant: by default, all windows use their
1467 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1468 if some of the parents attributes are explicitly (that is, using
1469 \helpref{SetFont}{wxwindowsetfont} and not
1470 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1471 corresponding attribute hadn't been explicitly set for this window itself,
1472 then this window takes the same value as used by the parent. In addition, if
1473 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1474 to return \false, the colours will not be changed no matter what and only the
1475 font might.
1476
1477 This rather complicated logic is necessary in order to accommodate the
1478 different usage scenarios. The most common one is when all default attributes
1479 are used and in this case, nothing should be inherited as in modern GUIs
1480 different controls use different fonts (and colours) than their siblings so
1481 they can't inherit the same value from the parent. However it was also deemed
1482 desirable to allow to simply change the attributes of all children at once by
1483 just changing the font or colour of their common parent, hence in this case we
1484 do inherit the parents attributes.

1689
1690 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1691
1692 Moves this window in the tab navigation order after the specified \arg{win}.
1693 This means that when the user presses \texttt{TAB} key on that other window,
1694 the focus switches to this window.
1695
1696 Default tab order is the same as creation order, this function and

1728 You may wish to call this from a text control custom keypress handler to do the default

1731 and not navigate to the next control.

2206
2207 This virtual function is normally only used internally, but
2208 sometimes an application may need it to implement functionality
2209 that should not be disabled by an application defining an OnIdle
2210 handler in a derived class.
2211
2212 This function may be used to do delayed painting, for example,
2213 and most implementations call \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}

2250
2251 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2252
2253 Pops up the given menu at the specified coordinates, relative to this
2254 window, and returns control when the user has dismissed the menu. If a
2255 menu item is selected, the corresponding menu event is generated and will be
2256 processed as usually. If the coordinates are not specified, current mouse
2257 cursor position is used.

2278
2279 It is recommended to not explicitly specify coordinates when calling PopupMenu
2280 in response to mouse click, because some of the ports (namely, wxGTK) can do
2281 a better job of positioning the menu in that case.

2298 \wxheading{Parameters}
2299
2300 \docparam{handler}{Specifies the handler to be pushed.}
2301
2302 \wxheading{Remarks}
2303
2304 An event handler is an object that is capable of processing the events
2305 sent to a window. By default, the window is its own event handler, but
2306 an application may wish to substitute another, for example to allow
2307 central implementation of event-handling for a variety of different
2308 window classes.
2309
2310 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2311 an application to set up a chain of event handlers, where an event not handled by one event handler is
2312 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2313 remove the event handler.

2340
2341 Causes this window, and all of its children recursively (except under wxGTK1
2342 where this is not implemented), to be repainted. Note that repainting doesn't
2343 happen immediately but only during the next event loop iteration, if you need

2365 repainted.
2366
2367 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2376 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2377 will receive a hotkey event. It will receive the event even if the application is in the background
2378 and does not have the input focus because the user is working with some other application.

2380 \wxheading{Parameters}
2381
2382 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2585
2586 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2587 be called automatically when the window is resized. Please note that this only
2588 happens for the windows usually used to contain children, namely
2589 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2590 (and the classes deriving from them).
2591
2592 This method is called implicitly by
2593 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2594 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2595 manually or otherwise the window layout won't be correctly updated when its
2596 size changes.
2597

2614 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2615 explanation of the difference between this method and
2616 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.

2618 \wxheading{Parameters}
2619
2620 \docparam{colour}{The colour to be used as the background colour, pass
2621 {\tt wxNullColour} to reset to the default colour.}
2622
2623 \wxheading{Remarks}
2624
2625 The background colour is usually painted by the default\rtfsp
2626 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2627 under Windows and automatically under GTK.
2628
2629 Note that setting the background colour does not cause an immediate refresh, so you
2630 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2631 calling this function.
2632
2633 Using this function will disable attempts to use themes for this
2634 window, if the system supports them. Use with care since usually the
2635 themes represent the appearance chosen by the user to be used for all
2636 applications on the system.

2653 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2654 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2655 application to implement (wxBG\_STYLE\_CUSTOM).
2656
2657 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2673 the value passed in for use with sizers. This means that if a full or
2674 partial size is passed to this function then the sizers will use that
2675 size instead of the results of GetBestSize to determine the minimum
2676 needs of the window for layout.
2677
2678 Most controls will use this to set their initial size, and their min

2700 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2701
2702 This sets the size of the window client area in pixels. Using this function to size a window
2703 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2704 worry about what dimensions the border or title bar have when trying to fit the window
2705 around panel items, for example.

2727
2728 Sets the window to have the given layout constraints. The window
2729 will then own the object, and will take care of its deletion.
2730 If an existing layout constraints object is already owned by the
2731 window, it will be deleted.

2739
2740 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2741 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2742 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2803 \wxheading{Parameters}
2804
2805 \docparam{handler}{Specifies the handler to be set.}
2806
2807 \wxheading{Remarks}
2808
2809 An event handler is an object that is capable of processing the events
2810 sent to a window. By default, the window is its own event handler, but
2811 an application may wish to substitute another, for example to allow
2812 central implementation of event-handling for a variety of different
2813 window classes.
2814
2815 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2816 this sets up a chain of event handlers, where an event not handled by one event handler is
2817 handed to the next one in the chain.

2841 events are propagated upwards to the window parent recursively until a handler
2842 for them is found. Using this style allows to prevent them from being
2843 propagated beyond this window. Notice that wxDialog has this style on by
2844 default for the reasons explained in the
2845 \helpref{event processing overview}{eventprocessing}.}
2846 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2847 window from being used as an implicit parent for the dialogs which were
2848 created without a parent. It is useful for the windows which can disappear at
2849 any moment as creating children of such windows results in fatal problems.}
2850 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2851 button on the caption. When pressed, Windows will go into a context-sensitive

2854 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2855 these two styles are automatically turned of if this one is used.}

2879
2880 This function is called by wxWidgets keyboard navigation code when the user
2881 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2882 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2891 parent window if you don't want its font to be inherited by its children,
2892 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2893 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2894 explanations.
2895
2896 Please notice that the given font is \emph{not} automatically used for
2897 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2898 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3094 Let's say you wish to display 50 lines of text, using the same font.
3095 The window is sized so that you can only see 16 lines at a time.
3096
3097 You would use:
3098
3099 {\small%
3100 \begin{verbatim}
3101 SetScrollbar(wxVERTICAL, 0, 16, 50);
3102 \end{verbatim}
3103 }
3104
3105 Note that with the window at this size, the thumb position can never go
3106 above 50 minus 16, or 34.
3107
3108 You can determine how many lines are currently visible by dividing the current view
3109 size by the character height in pixels.
3110
3111 When defining your own scrollbar behaviour, you will always need to recalculate
3112 the scrollbar settings when the window size changes. You could therefore put your
3113 scrollbar calculations and SetScrollbar
3114 call into a function named AdjustScrollbars, which can be called initially and also
3115 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3139
3140 \wxheading{Remarks}
3141
3142 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3143 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3144 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3145 value has to be adjusted when the window is resized, since the page size will have changed.
3146
3147 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3148 the thumb changes size to reflect the page size relative to the length of the document. When the
3149 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3150 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3151 disappear.
3152
3153 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3154 handling of pages and ranges.

3209
3210 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3211 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3212 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3213 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3214 and usually the scrollbar will be automatically hidden.

3260
3261 {\bf wxSIZE\_AUTO\_WIDTH}: a $wxDefaultCoord$ width value is taken to indicate

3263 {\bf wxSIZE\_AUTO\_HEIGHT}: a $wxDefaultCoord$ height value is taken to indicate

3270 as real dimensions, not default values.
3271 {\bf wxSIZE\_FORCE}: normally, if the position and the size of the window are
3272 already the same as the parameters of this function, nothing is done. but with

3281
3282 The first form sets the position and optionally size, of the window.
3283 Parameters may be $wxDefaultCoord$ to indicate either that a default should be supplied

3313
3314 \func{void}{SetSizer}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3315
3316 Sets the window to have the given layout sizer. The window
3317 will then own the object, and will take care of its deletion.
3318 If an existing layout constraints object is already owned by the
3319 window, it will be deleted if the deleteOld parameter is true.
3320
3321 Note that this function will also call
3322 \helpref{SetAutoLayout}{wxwindowsetautolayout} implicitly with {\tt true}
3323 parameter if the {\it sizer}\/ is non-NULL and {\tt false} otherwise.
3324
3325 \wxheading{Parameters}
3326
3327 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and conditionally delete
3328 the window's sizer. See below.}
3329
3330 \docparam{deleteOld}{If true (the default), this will delete any prexisting sizer.
3331 Pass false if you wish to handle deleting the old sizer yourself.}

3334
3335 SetSizer now enables and disables Layout automatically, but prior to wxWidgets 2.3.3
3336 the following applied:
3337
3338 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3339 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3340 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3341 only the sizer will have effect.

3353
3354 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
3355
3356 This function tells a window if it should use the system's "theme" code
3357 to draw the windows' background instead if its own background drawing
3358 code. This does not always have any effect since the underlying platform
3359 obviously needs to support the notion of themes in user defined windows.
3360 One such platform is GTK+ where windows can have (very colourful) backgrounds
3361 defined by a user's selected theme.
3362
3363 Dialogs, notebook pages and the status bar have this flag set to true
3364 by default so that the default look and feel is simulated best.

3453
3454 This function can be called under all platforms but only does anything under
3455 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3456 exist in several sizes which correspond to the elements of wxWindowVariant
3457 enum:
3458 \begin{verbatim}
3459 enum wxWindowVariant
3460 {
3461 wxWINDOW_VARIANT_NORMAL, // Normal size
3462 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3463 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3464 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3465 };

3582
3583 Calling this method immediately repaints the invalidated area of the window and
3584 all of its children recursively while this would usually only happen when the
3585 flow of control returns to the event loop.
3586 Notice that this function doesn't invalidate any area of the window so
3587 nothing happens if nothing has been invalidated (i.e. marked as requiring
3588 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3589 immediately redraw the window unconditionally.

3592 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3593
3594 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3595
3596 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3597 the window. The particular implementation depends on the window; for
3598 example a wxToolBar will send an update UI event for each toolbar button,
3599 and a wxFrame will send an update UI event for each menubar menu item.
3600 You can call this function from your application to ensure that your
3601 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3602 are concerned). This may be necessary if you have called
3603 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3604 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3605 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3606
3607 {\it flags} should be a bitlist of one or more of the following values.
3608
3609 \begin{verbatim}
3610 enum wxUpdateUI
3611 {
3612 wxUPDATE_UI_NONE = 0x0000, // No particular value
3613 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3614 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3615 };
3616 \end{verbatim}
3617
3618 If you are calling this function from an OnInternalIdle or OnIdle
3619 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3620 this tells the window to only update the UI elements that need
3621 to be updated in idle time. Some windows update their elements
3622 only when necessary, for example when a menu is about to be shown.
3623 The following is an example of how to call UpdateWindowUI from
3624 an idle function.
3625
3626 \begin{verbatim}
3627 void MyWindow::OnInternalIdle()
3628 {
3629 if (wxUpdateUIEvent::CanUpdate(this))
