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

44\wxheading{Window styles}
45
46The following styles can apply to all windows, although they will not always make sense for a particular
47window 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
52for 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
59events. 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
62the window wants to get all char/key events for all keys - even for
63keys like TAB or ENTER which are usually used for dialog navigation
64and which wouldn't be generated without this style. If you need to
65use this style in order to get the arrows or etc., but would still like
66to have normal keyboard navigation take place, you should call
67\helpref{Navigate}{wxwindownavigate} in response to the key events for
68Tab and Shift-Tab.}
69\twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
70the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
71and 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,
75disable them instead of hiding them when they are not needed (i.e. when the
76size of the window is big enough to not require the scrollbars to navigate it).
77This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
78nothing on the other platforms.}
79\twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80repainted, then children being painted over them. Windows only.}
81\twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
82a complete redraw of the window whenever it is resized instead of redrawing
83just the part of the window affected by resizing. Note that this was the
84behaviour by default before 2.5.1 release and that if you experience redraw
85problems with code which previously used to work you may want to try this.
86Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
87done on other platforms.}

92\wxheading{Extra window styles}
93
94The 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()
99only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
100descend into all subwindows.}
101\twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
102parent window and so on recursively by default. Using this flag for the
103given window allows to block this propagation at this window, i.e. prevent
104the events from being propagated further upwards. Dialogs have this
105flag on by default.}
106\twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
107be used with transient windows as otherwise there is the risk of creating a
108dialog/frame with this window as a parent which would lead to a crash if the
109parent is destroyed before the child.}
110\twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
111if 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,
113even 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
128Default 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
136Constructs 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
145should generate a default position for the window. If using the wxWindow class directly, supply
146an actual position.}
147
148\docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
149should generate a default size for the window. If no suitable size can be found, the
150window will be sized to 20x20 pixels so that the window is visible but obviously not
151correctly 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
162Destructor. Deletes all subwindows, then deletes itself. Instead of using
163the {\bf delete} operator explicitly, you should normally
164use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
165can delete a window only when it is safe to do so, in idle time.

173
174\membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
175
176\constfunc{bool}{AcceptsFocus}{\void}
177
178This method may be overridden in the derived classes to return \false to
179indicate that this control doesn't accept input at all (i.e. behaves like e.g.
180\helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
181
182\wxheading{See also}

184\helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
185
186
187\membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
188
189\constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
190
191This method may be overridden in the derived classes to return \false to
192indicate that while this control can, in principle, have focus if the user
193clicks it with the mouse, it shouldn't be included in the TAB traversal chain
194when using the keyboard.
195
196
197\membersection{wxWindow::AddChild}\label{wxwindowaddchild}
198
199\func{virtual void}{AddChild}{\param{wxWindow* }{child}}
200
201Adds a child window. This is called automatically by window creation
202functions so should not be required by the application programmer.
203
204Notice that this function is mostly internal to wxWidgets and shouldn't be
205called by the user code.
206
207\wxheading{Parameters}
208
209\docparam{child}{Child window to add.}
210
211
212\membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
213
214\constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
215
216Sets the cached best size value.
217
218
219\membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
220
221\func{virtual void}{CaptureMouse}{\void}
222
223Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
224release the capture.
225
226Note that wxWidgets maintains the stack of windows having captured the mouse
227and when the mouse is released the capture returns to the window which had had
228captured it previously and it is only really released if there were no previous
229window. In particular, this means that you must release the mouse as many times
230as you capture it, unless the window receives
231the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
232
233Any application which captures the mouse in the beginning of some operation
234{\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
235and cancel this operation when it receives the event. The event handler must
236not recapture mouse.

263
264
265\membersection{wxWindow::Centre}\label{wxwindowcentre}
266
267\func{void}{Centre}{\param{int}{ direction = wxBOTH}}
268
269Centres the window.
270
271\wxheading{Parameters}
272
273\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
274or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
275if you want to center the window on the entire screen and not on its
276parent window.}
277
278The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
279(it has no effect).
280
281\wxheading{Remarks}
282
283If the window is a top level one (i.e. doesn't have a parent), it will be
284centered relative to the screen anyhow.

292
293\func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
294
295Centres the window on its parent. This is a more readable synonym for
296\helpref{Centre}{wxwindowcentre}.
297
298\wxheading{Parameters}
299
300\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
301or {\tt wxBOTH}.}
302
303\wxheading{Remarks}
304
305This methods provides for a way to center top level windows over their
306parents instead of the entire screen. If there is no parent or if the
307window is not a top level window, then behaviour is the same as
308\helpref{wxWindow::Centre}{wxwindowcentre}.

316
317\func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
318
319Centres the window on screen. This only works for top level windows -
320otherwise, the window will still be centered on its parent.
321
322\wxheading{Parameters}
323
324\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
325or {\tt wxBOTH}.}

339
340\membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
341
342\constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
343
344\perlnote{In wxPerl this method returns a 2-element list instead of
345modifying its parameters.}
346
347\constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
348
349Converts to screen coordinates from coordinates relative to this window.
350
351\docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
352a screen coordinate will be passed out.}

355a screen coordinate will be passed out.}
356
357\docparam{pt}{The client position for the second form of the function.}
358
359\pythonnote{In place of a single overloaded method name, wxPython

366
367
368\membersection{wxWindow::Close}\label{wxwindowclose}
369
370\func{bool}{Close}{\param{bool}{ force = {\tt false}}}
371
372This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
373handler usually tries to close the window. It doesn't close the window itself,
374however.
375
376\wxheading{Parameters}
377
378\docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
379of this window, {\tt true} if it cannot.}
380
381\wxheading{Remarks}
382
383Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
384an opportunity for the window to choose whether to destroy the window.
385Usually it is only used with the top level windows (wxFrame and wxDialog
386classes) as the others are not supposed to have any special OnClose() logic.
387
388The close handler should check whether the window is being deleted forcibly,
389using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
390should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
391
392{\it Note} that calling Close does not guarantee that the window will be
393destroyed; but it provides a way to simulate a manual close of a window, which
394may or may not be implemented by destroying the window. The default
395implementation of wxDialog::OnCloseWindow does not necessarily delete the
396dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
397the appropriate button event handler and may do anything at all.
398
399To guarantee that the window will be destroyed, call
400\helpref{wxWindow::Destroy}{wxwindowdestroy} instead

410
411\func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
412
413\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
414
415Converts a point or size from dialog units to pixels.
416
417For the x dimension, the dialog units are multiplied by the average character width
418and then divided by 4.
419
420For the y dimension, the dialog units are multiplied by the average character height
421and then divided by 8.
422
423\wxheading{Remarks}
424
425Dialog units are used for maintaining a dialog's proportions even if the font changes.
426
427You can also use these functions programmatically. A convenience macro is defined:
428
429{\small
430\begin{verbatim}
431#define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

488
489\func{virtual bool}{Destroy}{\void}
490
491Destroys the window safely. Use this function instead of the delete operator, since
492different window classes can be destroyed differently. Frames and dialogs
493are not destroyed immediately when this function is called -- they are added
494to a list of windows to be deleted on idle time, when all the window's events
495have been processed. This prevents problems with events being sent to non-existent
496windows.
497

537This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
538in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
539act appropriately. For example, to allow frame and dialog title updating, wxWidgets
540implements this function as follows:
541
542\begin{verbatim}
543// do the window-specific processing after processing the update event
544void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
545{

680\membersection{wxWindow::Fit}\label{wxwindowfit}
681
682\func{virtual void}{Fit}{\void}
683
684Sizes the window so that it fits around its subwindows. This function won't do
685anything if there are no subwindows and will only really work correctly if
686sizers are used for the subwindows layout. Also, if the window has exactly one
687subwindow it is better (faster and the result is more precise as Fit adds some
688margin to account for fuzziness of its calculations) to call
689
690\begin{verbatim}
691 window->SetClientSize(child->GetSize());

694instead of calling Fit.
695

697\membersection{wxWindow::FitInside}\label{wxwindowfitinside}
698
699\func{virtual void}{FitInside}{\void}
700
701Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
702of a window. Mainly useful with scrolled windows to reset scrollbars after
703sizing changes that do not trigger a size event, and/or scrolled windows without
704an interior sizer. This function similarly won't do anything if there are no
705subwindows.
706
707
708\membersection{wxWindow::Freeze}\label{wxwindowfreeze}
709
710\func{virtual void}{Freeze}{\void}
711
712Freezes the window or, in other words, prevents any updates from taking place
713on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
714be called to reenable window redrawing. Calls to these two functions may be
715nested.
716
717This method is useful for visual appearance optimization (for example, it
718is a good idea to use it before doing many large text insertions in a row into
719a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
720controls so it is mostly just a hint to wxWidgets and not a mandatory
721directive.

769whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
770be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
771application to implement (wxBG\_STYLE\_CUSTOM).
772
773On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
774background, such as a tiled bitmap. Currently the style has no effect on other platforms.

801example, for a static control, it will be the minimal size such that the
802control label is not truncated. For windows containing subwindows (typically
803\helpref{wxPanel}{wxpanel}), the size returned by this function will be the
804same as the size the window would have had after calling

847
848\constfunc{const wxWindowList\&}{GetChildren}{\void}
849
850Returns a reference to the list of the window's children. \texttt{wxWindowList}
851is a type-safe \helpref{wxList}{wxlist}-like class whose elements are of type
852\texttt{wxWindow *}.

856
857\func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
858
859Returns the default font and colours which are used by the control. This is
860useful if you want to use the same font or colour in your own control as in a
861standard control -- which is a much better idea than hard coding specific
862colours or fonts which might look completely out of place on the users
863system, especially if it uses themes.
864
865The \arg{variant} parameter is only relevant under Mac currently and is
866ignore under other platforms. Under Mac, it will change the size of the
867returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
868for more about this.
869
870This static method is ``overridden'' in many derived classes and so calling,
871for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
872return the values appropriate for a button which will be normally different
873from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
874
875The \texttt{wxVisualAttributes} structure has at least the fields
876\texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
877if it was not possible to determine the default control appearance or,
878especially for the background colour, if the field doesn't make sense as is
879the case for \texttt{colBg} for the controls with themed background.

953Currently this is the same as calling
954\helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
955
956One advantage of using this function compared to the static version is that
957the call is automatically dispatched to the correct class (as usual with
958virtual functions) and you don't have to specify the class name explicitly.
959
960The other one is that in the future this function could return different
961results, for example it might return a different font for an ``Ok'' button
962than for a generic button if the users GUI is configured to show such buttons
963in bold font. Of course, the down side is that it is impossible to call this
964function without actually having an object to apply it to whereas the static
965version can be used without having to create an object first.

1108
1109The interpretation of this function differs from class to class.
1110For frames and dialogs, the value returned is the title. For buttons or static text controls, it is
1111the button text. This function can be useful for meta-programs (such as testing
1112tools or special-needs access programs) which need to identify windows
1113by name.

1484
1485This method is mostly used internally by the library itself and you normally
1486shouldn't have to call it. You may, however, have to override it in your

1497\membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1498
1499\func{void}{InheritAttributes}{\void}
1500
1501This function is (or should be, in case of custom controls) called during
1502window creation to intelligently set up the window visual attributes, that is
1503the font and the foreground and background colours.
1504
1505By ``intelligently'' the following is meant: by default, all windows use their
1506own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1507if some of the parents attributes are explicitly (that is, using
1508\helpref{SetFont}{wxwindowsetfont} and not
1509\helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1510corresponding attribute hadn't been explicitly set for this window itself,
1511then this window takes the same value as used by the parent. In addition, if
1512the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1513to return \false, the colours will not be changed no matter what and only the
1514font might.
1515
1516This rather complicated logic is necessary in order to accommodate the
1517different usage scenarios. The most common one is when all default attributes
1518are used and in this case, nothing should be inherited as in modern GUIs
1519different controls use different fonts (and colours) than their siblings so
1520they can't inherit the same value from the parent. However it was also deemed
1521desirable to allow to simply change the attributes of all children at once by
1522just changing the font or colour of their common parent, hence in this case we
1523do inherit the parents attributes.

1746
1747Moves this window in the tab navigation order after the specified \arg{win}.
1748This means that when the user presses \texttt{TAB} key on that other window,
1749the focus switches to this window.
1750

1809function allows to retrieve the effective id of the latter control from the id
1810of the former. This is useful for example to find the control following its

2338\func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2339
2340Pops up the given menu at the specified coordinates, relative to this
2341window, and returns control when the user has dismissed the menu. If a
2342menu item is selected, the corresponding menu event is generated and will be
2343processed as usually. If the coordinates are not specified, current mouse

2394
2395\docparam{handler}{Specifies the handler to be pushed.}
2396
2397\wxheading{Remarks}
2398
2399An event handler is an object that is capable of processing the events
2400sent to a window. By default, the window is its own event handler, but
2401an application may wish to substitute another, for example to allow
2402central implementation of event-handling for a variety of different
2403window classes.
2404
2405\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2406an application to set up a chain of event handlers, where an event not handled by one event handler is
2407handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2408remove the event handler.

2436Causes this window, and all of its children recursively (except under wxGTK1
2437where this is not implemented), to be repainted. Note that repainting doesn't
2438happen immediately but only during the next event loop iteration, if you need

2460repainted.
2461
2462This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2470
2471Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2472will receive a hotkey event. It will receive the event even if the application is in the background
2473and does not have the input focus because the user is working with some other application.
2474
2475\wxheading{Parameters}
2476
2477\docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2688\helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2689\helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2690manually or otherwise the window layout won't be correctly updated when its
2691size changes.
2692
2693\wxheading{Parameters}
2694
2695\docparam{autoLayout}{Set this to \true if you wish the Layout function to be
2696called automatically when the window is resized.}

2704
2705\func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2706
2707Sets the background colour of the window.
2708
2709Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2710explanation of the difference between this method and
2711\helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2712
2713\wxheading{Parameters}
2714
2715\docparam{colour}{The colour to be used as the background colour, pass
2716 {\tt wxNullColour} to reset to the default colour.}
2717
2718\wxheading{Remarks}
2719
2720The background colour is usually painted by the default\rtfsp
2721\helpref{wxEraseEvent}{wxeraseevent} event handler function
2722under Windows and automatically under GTK.
2723
2724Note that setting the background colour does not cause an immediate refresh, so you
2725may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2726calling this function.
2727
2728Using this function will disable attempts to use themes for this
2729window, if the system supports them. Use with care since usually the
2730themes represent the appearance chosen by the user to be used for all
2731applications on the system.

2743\membersection{wxWindow::SetBackgroundStyle}\label{wxwindowsetbackgroundstyle}
2744
2745\func{virtual void}{SetBackgroundStyle}{\param{wxBackgroundStyle}{ style}}
2746
2747Sets the background style of the window. The background style indicates
2748whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2749be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2750application to implement (wxBG\_STYLE\_CUSTOM).
2751
2752On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2753background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2763
2764\func{void}{SetInitialSize}{\param{const wxSize\& }{size = wxDefaultSize}}
2765
2766A {\it smart} SetSize that will fill in default size components with the
2767window's {\it best} size values. Also sets the window's minsize to
2768the value passed in for use with sizers. This means that if a full or
2769partial size is passed to this function then the sizers will use that
2770size instead of the results of GetBestSize to determine the minimum
2771needs of the window for layout.
2772
2773Most controls will use this to set their initial size, and their min
2774size to the passed in value (if any.)

2793\func{virtual void}{SetClientSize}{\param{int}{ width}, \param{int}{ height}}
2794
2795\func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2796
2797This sets the size of the window client area in pixels. Using this function to size a window
2798tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2799worry about what dimensions the border or title bar have when trying to fit the window
2800around panel items, for example.
2801
2802\wxheading{Parameters}
2803
2804\docparam{width}{The required client area width.}
2805
2806\docparam{height}{The required client area height.}

2819\membersection{wxWindow::SetConstraints}\label{wxwindowsetconstraints}
2820
2821\func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2822
2823Sets the window to have the given layout constraints. The window
2824will then own the object, and will take care of its deletion.
2825If an existing layout constraints object is already owned by the
2826window, it will be deleted.
2827
2828\wxheading{Parameters}
2829
2830\docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2831constraints.}
2832
2833\wxheading{Remarks}
2834
2835You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2836the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2837explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2838sizer will have effect.
2839
2840\membersection{wxWindow::SetContainingSizer}\label{wxwindowsetcontainingsizer}
2841
2842\func{void}{SetContainingSizer}{\param{wxSizer* }{sizer}}
2843
2844This normally does not need to be called by user code. It is called
2845when a window is added to a sizer, and is used so the window can
2846remove itself from the sizer when it is destroyed.

2854% changed
2855Sets the window's cursor. Notice that the window cursor also sets it for the
2856children of the window implicitly.
2857
2858The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2859be reset back to default.

2890components of the size passed to ctor/Create() is wxDefaultCoord).
2891
2892\membersection{wxWindow::SetEventHandler}\label{wxwindowseteventhandler}
2893
2894\func{void}{SetEventHandler}{\param{wxEvtHandler* }{handler}}
2895
2896Sets the event handler for this window.
2897
2898\wxheading{Parameters}
2899
2900\docparam{handler}{Specifies the handler to be set.}
2901
2902\wxheading{Remarks}
2903
2904An event handler is an object that is capable of processing the events
2905sent to a window. By default, the window is its own event handler, but
2906an application may wish to substitute another, for example to allow
2907central implementation of event-handling for a variety of different
2908window classes.
2909
2910It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2911this sets up a chain of event handlers, where an event not handled by one event handler is
2912handed to the next one in the chain.

2924
2925\func{void}{SetExtraStyle}{\param{long }{exStyle}}
2926
2927Sets the extra style bits for the window. The currently defined extra style
2928bits are:
2929
2930\twocolwidtha{5cm}%
2931\begin{twocollist}\itemsep=0pt
2932\twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2933and Validate() methods will recursively descend into all children of the
2934window if it has this style flag set.}
2935\twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2936events are propagated upwards to the window parent recursively until a handler
2937for them is found. Using this style allows to prevent them from being
2938propagated beyond this window. Notice that wxDialog has this style on by
2939default for the reasons explained in the
2940\helpref{event processing overview}{eventprocessing}.}
2941\twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2942window from being used as an implicit parent for the dialogs which were
2943created without a parent. It is useful for the windows which can disappear at
2944any moment as creating children of such windows results in fatal problems.}
2945\twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2946button on the caption. When pressed, Windows will go into a context-sensitive
2947help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an
2948application window.
2949This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2950these two styles are automatically turned of if this one is used.}
2951\twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
2952if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}

2972
2973\func{virtual void}{SetFocusFromKbd}{\void}
2974
2975This function is called by wxWidgets keyboard navigation code when the user
2976gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2977By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but
2978can be overridden to do something in addition to this in the derived classes.

2981\membersection{wxWindow::SetFont}\label{wxwindowsetfont}
2982
2983\func{void}{SetFont}{\param{const wxFont\& }{font}}
2984
2985Sets the font for this window. This function should not be called for the
2986parent window if you don't want its font to be inherited by its children,
2987use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2988see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2989explanations.
2990
2991Please notice that the given font is \emph{not} automatically used for
2992\helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2993call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by
2994any standard controls for drawing their text as well as by
2995\helpref{wxWindow::GetTextExtent()}{wxwindowgettextextent}.

3012Sets the foreground colour of the window.
3013
3014Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
3015explanation of the difference between this method and
3016\helpref{SetOwnForegroundColour}{wxwindowsetownforegroundcolour}.

3024
3025The interpretation of foreground colour is open to interpretation according
3026to the window class; it may be the text colour or other colour, or it may not
3027be used at all.

3029Using this function will disable attempts to use themes for this

3187\wxheading{Remarks}
3188
3189Let's say you wish to display 50 lines of text, using the same font.
3190The window is sized so that you can only see 16 lines at a time.
3191
3192You would use:
3193
3194{\small%
3195\begin{verbatim}
3196 SetScrollbar(wxVERTICAL, 0, 16, 50);
3197\end{verbatim}
3198}
3199
3200Note that with the window at this size, the thumb position can never go
3201above 50 minus 16, or 34.
3202
3203You can determine how many lines are currently visible by dividing the current view
3204size by the character height in pixels.
3205
3206When defining your own scrollbar behaviour, you will always need to recalculate

3223\func{virtual void}{SetScrollPage}{\param{int }{orientation}, \param{int }{pageSize}, \param{bool }{refresh = {\tt true}}}

3236
3237The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3238click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3239page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3240value has to be adjusted when the window is resized, since the page size will have changed.
3241
3242In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3243the thumb changes size to reflect the page size relative to the length of the document. When the
3244document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3245will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3246disappear.
3247
3248Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3249handling of pages and ranges.

3303\wxheading{Remarks}
3304
3305The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3306object length of the scrollbar. If you are implementing a scrolling window, for example, you
3307would adjust the scroll range when the window is resized, by subtracting the window view size from the
3308total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3309and usually the scrollbar will be automatically hidden.

3413If an existing layout constraints object is already owned by the

3416Note that this function will also call

3451This function tells a window if it should use the system's "theme" code
3452to draw the windows' background instead if its own background drawing
3453code. This does not always have any effect since the underlying platform
3454obviously needs to support the notion of themes in user defined windows.
3455One such platform is GTK+ where windows can have (very colourful) backgrounds
3456defined by a user's selected theme.

3702all of its children recursively while this would usually only happen when the
3703flow of control returns to the event loop.
3704Notice that this function doesn't invalidate any area of the window so
3705nothing happens if nothing has been invalidated (i.e. marked as requiring

3714This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3715the window. The particular implementation depends on the window; for
3716example a wxToolBar will send an update UI event for each toolbar button,
3717and a wxFrame will send an update UI event for each menubar menu item.
3718You can call this function from your application to ensure that your
3719UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3720are concerned). This may be necessary if you have called
3721\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3722\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3723limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3724
3725{\it flags} should be a bitlist of one or more of the following values.
3726
3727\begin{verbatim}
3728enum wxUpdateUI
3729{
3730 wxUPDATE_UI_NONE = 0x0000, // No particular value
3731 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3732 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3733};
3734\end{verbatim}
3735
3736If you are calling this function from an OnInternalIdle or OnIdle
3737function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3738this tells the window to only update the UI elements that need
3739to be updated in idle time. Some windows update their elements
3740only when necessary, for example when a menu is about to be shown.
3741The following is an example of how to call UpdateWindowUI from
3742an idle function.
3743
3744\begin{verbatim}
3745void MyWindow::OnInternalIdle()
3746{
3747 if (wxUpdateUIEvent::CanUpdate(this))
3748 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3749}
3750\end{verbatim}

3759\membersection{wxWindow::Validate}\label{wxwindowvalidate}
3760
3761\func{virtual bool}{Validate}{\void}
3762
3763Validates the current values of the child controls using their validators.
3764
3765If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3766the method will also call Validate() of all child windows.
3767
3768\wxheading{Return value}
3769
3770Returns {\tt false} if any of the validations failed.
