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.

50 The following styles can apply to all windows, although they will not always make sense for a particular
51 window class or on all platforms.
52
53 \twocolwidtha{5cm}%
54 \begin{twocollist}\itemsep=0pt
55 \twocolitem{\windowstyle{wxBORDER\_DEFAULT}}{The window class will decide the kind of border to show, if any.}
56 \twocolitem{\windowstyle{wxBORDER\_SIMPLE}}{Displays a thin border around the window. wxSIMPLE\_BORDER is the old name
57 for this style. }
58 \twocolitem{\windowstyle{wxBORDER\_SUNKEN}}{Displays a sunken border. wxSUNKEN\_BORDER is the old name for this style.}
59 \twocolitem{\windowstyle{wxBORDER\_RAISED}}{Displays a raised border. wxRAISED\_BORDER is the old name for this style. }
60 \twocolitem{\windowstyle{wxBORDER\_STATIC}}{Displays a border suitable for a static control. wxSTATIC\_BORDER is the old name for this style. Windows only. }
61 \twocolitem{\windowstyle{wxBORDER\_THEME}}{Displays a native border suitable for a control, on the current platform. On Windows XP or Vista, this will be a themed border; on most other platforms
62 a sunken border will be used. For more information for themed borders on Windows, please see \helpref{Themed borders on Windows}{wxmswthemedborders}.}
63 \twocolitem{\windowstyle{wxBORDER\_NONE}}{Displays no border, overriding the default border style for the window. wxNO\_BORDER is the old name for this style.}
64 \twocolitem{\windowstyle{wxBORDER\_DOUBLE}}{This style is obsolete and should not be used.}
65 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
66 events. Windows only.}
67 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
68 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
69 the window wants to get all char/key events for all keys - even for
70 keys like TAB or ENTER which are usually used for dialog navigation
71 and which wouldn't be generated without this style. If you need to
72 use this style in order to get the arrows or etc., but would still like
73 to have normal keyboard navigation take place, you should call
74 \helpref{Navigate}{wxwindownavigate} in response to the key events for
75 Tab and Shift-Tab.}
76 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
77 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
78 and no longer has an effect.}
79 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical
80 scrollbar. Notice that this style cannot be used with native controls
81 which don't support scrollbars nor with top-level windows in most ports.}
82 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal
83 scrollbar. The same limitations as for wxVSCROLL apply to this style.}
84 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
85 disable them instead of hiding them when they are not needed (i.e. when the
86 size of the window is big enough to not require the scrollbars to navigate it).
87 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
88 nothing on the other platforms.}
89 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
90 repainted, then children being painted over them. Windows only.}
91 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
92 a complete redraw of the window whenever it is resized instead of redrawing
93 just the part of the window affected by resizing. Note that this was the
94 behaviour by default before 2.5.1 release and that if you experience redraw
95 problems with code which previously used to work you may want to try this.
96 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
97 done on other platforms.}

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

134 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
135
136 \func{}{wxWindow}{\void}
137
138 Default constructor.
139
140 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
141 \param{const wxPoint\& }{pos = wxDefaultPosition},
142 \param{const wxSize\& }{size = wxDefaultSize},
143 \param{long }{style = 0},
144 \param{const wxString\& }{name = wxPanelNameStr}}
145
146 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
147
148 \wxheading{Parameters}
149
150 \docparam{parent}{Pointer to a parent window.}
151
152 \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
153
154 \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
155 should generate a default position for the window. If using the wxWindow class directly, supply
156 an actual position.}
157
158 \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
159 should generate a default size for the window. If no suitable size can be found, the
160 window will be sized to 20x20 pixels so that the window is visible but obviously not
161 correctly sized. }
162
163 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
164
165 \docparam{name}{Window name.}
166
167
168 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
169
170 \func{}{\destruct{wxWindow}}{\void}
171
172 Destructor. Deletes all subwindows, then deletes itself. Instead of using
173 the {\bf delete} operator explicitly, you should normally
174 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
175 can delete a window only when it is safe to do so, in idle time.

183
184 \membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
185
186 \constfunc{bool}{AcceptsFocus}{\void}
187
188 This method may be overridden in the derived classes to return \false to
189 indicate that this control doesn't accept input at all (i.e. behaves like e.g.
190 \helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
191
192 \wxheading{See also}

194 \helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
195
196
197 \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
198
199 \constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
200
201 This method may be overridden in the derived classes to return \false to
202 indicate that while this control can, in principle, have focus if the user
203 clicks it with the mouse, it shouldn't be included in the TAB traversal chain
204 when using the keyboard.
205
206
207 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
208
209 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
210
211 Adds a child window. This is called automatically by window creation
212 functions so should not be required by the application programmer.
213
214 Notice that this function is mostly internal to wxWidgets and shouldn't be
215 called by the user code.
216
217 \wxheading{Parameters}
218
219 \docparam{child}{Child window to add.}
220
221
222 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
223
224 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
225
226 Sets the cached best size value.
227
228
229 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
230
231 \func{virtual void}{CaptureMouse}{\void}
232
233 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
234 release the capture.
235
236 Note that wxWidgets maintains the stack of windows having captured the mouse
237 and when the mouse is released the capture returns to the window which had had
238 captured it previously and it is only really released if there were no previous
239 window. In particular, this means that you must release the mouse as many times
240 as you capture it, unless the window receives
241 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
242
243 Any application which captures the mouse in the beginning of some operation
244 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
245 and cancel this operation when it receives the event. The event handler must
246 not recapture mouse.

273
274
275 \membersection{wxWindow::Centre}\label{wxwindowcentre}
276
277 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
278
279 Centres the window.
280
281 \wxheading{Parameters}
282
283 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
284 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
285 if you want to center the window on the entire screen and not on its
286 parent window.}
287
288 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
289 (it has no effect).
290
291 \wxheading{Remarks}
292
293 If the window is a top level one (i.e. doesn't have a parent), it will be
294 centered relative to the screen anyhow.

302
303 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
304
305 Centres the window on its parent. This is a more readable synonym for
306 \helpref{Centre}{wxwindowcentre}.
307
308 \wxheading{Parameters}
309
310 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
311 or {\tt wxBOTH}.}
312
313 \wxheading{Remarks}
314
315 This methods provides for a way to center top level windows over their
316 parents instead of the entire screen. If there is no parent or if the
317 window is not a top level window, then behaviour is the same as
318 \helpref{wxWindow::Centre}{wxwindowcentre}.

326
327 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
328
329 Centres the window on screen. This only works for top level windows -
330 otherwise, the window will still be centered on its parent.
331
332 \wxheading{Parameters}
333
334 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

355 modifying its parameters.}
356
357 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
358
359 Converts to screen coordinates from coordinates relative to this window.
360
361 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
362 a screen coordinate will be passed out.}

377
378 \membersection{wxWindow::Close}\label{wxwindowclose}
379
380 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
381
382 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
383 handler usually tries to close the window. It doesn't close the window itself,
384 however.
385
386 \wxheading{Parameters}
387
388 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
389 of this window, {\tt true} if it cannot.}
390
391 \wxheading{Remarks}
392
393 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
394 an opportunity for the window to choose whether to destroy the window.
395 Usually it is only used with the top level windows (wxFrame and wxDialog
396 classes) as the others are not supposed to have any special OnClose() logic.
397
398 The close handler should check whether the window is being deleted forcibly,
399 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
400 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
401
402 {\it Note} that calling Close does not guarantee that the window will be
403 destroyed; but it provides a way to simulate a manual close of a window, which
404 may or may not be implemented by destroying the window. The default
405 implementation of wxDialog::OnCloseWindow does not necessarily delete the
406 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
407 the appropriate button event handler and may do anything at all.
408
409 To guarantee that the window will be destroyed, call
410 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

420
421 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
422
423 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
424
425 Converts a point or size from dialog units to pixels.
426
427 For the x dimension, the dialog units are multiplied by the average character width
428 and then divided by 4.
429
430 For the y dimension, the dialog units are multiplied by the average character height
431 and then divided by 8.
432
433 \wxheading{Remarks}
434
435 Dialog units are used for maintaining a dialog's proportions even if the font changes.
436
437 You can also use these functions programmatically. A convenience macro is defined:
438
439 {\small
440 \begin{verbatim}
441 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

498
499 \func{virtual bool}{Destroy}{\void}
500
501 Destroys the window safely. Use this function instead of the delete operator, since
502 different window classes can be destroyed differently. Frames and dialogs
503 are not destroyed immediately when this function is called -- they are added
504 to a list of windows to be deleted on idle time, when all the window's events
505 have been processed. This prevents problems with events being sent to non-existent
506 windows.
507
508 \wxheading{Return value}

546 Does the window-specific updating after processing the update event.
547 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
548 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
549 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
550 implements this function as follows:

693
694 Sizes the window so that it fits around its subwindows. This function won't do
695 anything if there are no subwindows and will only really work correctly if
696 sizers are used for the subwindows layout. Also, if the window has exactly one
697 subwindow it is better (faster and the result is more precise as Fit adds some
698 margin to account for fuzziness of its calculations) to call
699
700 \begin{verbatim}

712 of a window. Mainly useful with scrolled windows to reset scrollbars after
713 sizing changes that do not trigger a size event, and/or scrolled windows without
714 an interior sizer. This function similarly won't do anything if there are no
715 subwindows.
716
717
718 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

720 \func{virtual void}{Freeze}{\void}
721
722 Freezes the window or, in other words, prevents any updates from taking place
723 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
724 be called to reenable window redrawing. Calls to these two functions may be
725 nested.
726
727 This method is useful for visual appearance optimization (for example, it
728 is a good idea to use it before doing many large text insertions in a row into
729 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
730 controls so it is mostly just a hint to wxWidgets and not a mandatory

867 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
868
869 Returns the default font and colours which are used by the control. This is
870 useful if you want to use the same font or colour in your own control as in a
871 standard control -- which is a much better idea than hard coding specific
872 colours or fonts which might look completely out of place on the users
873 system, especially if it uses themes.
874
875 The \arg{variant} parameter is only relevant under Mac currently and is
876 ignore under other platforms. Under Mac, it will change the size of the
877 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
878 for more about this.
879
880 This static method is ``overridden'' in many derived classes and so calling,
881 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
882 return the values appropriate for a button which will be normally different
883 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
884
885 The \texttt{wxVisualAttributes} structure has at least the fields
886 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
887 if it was not possible to determine the default control appearance or,
888 especially for the background colour, if the field doesn't make sense as is
889 the case for \texttt{colBg} for the controls with themed background.

963 Currently this is the same as calling
964 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
965
966 One advantage of using this function compared to the static version is that
967 the call is automatically dispatched to the correct class (as usual with
968 virtual functions) and you don't have to specify the class name explicitly.
969
970 The other one is that in the future this function could return different
971 results, for example it might return a different font for an ``Ok'' button
972 than for a generic button if the users GUI is configured to show such buttons
973 in bold font. Of course, the down side is that it is impossible to call this
974 function without actually having an object to apply it to whereas the static
975 version can be used without having to create an object first.

1547
1548 \func{void}{InheritAttributes}{\void}
1549
1550 This function is (or should be, in case of custom controls) called during
1551 window creation to intelligently set up the window visual attributes, that is
1552 the font and the foreground and background colours.
1553
1554 By ``intelligently'' the following is meant: by default, all windows use their
1555 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1556 if some of the parents attributes are explicitly (that is, using
1557 \helpref{SetFont}{wxwindowsetfont} and not
1558 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1559 corresponding attribute hadn't been explicitly set for this window itself,
1560 then this window takes the same value as used by the parent. In addition, if
1561 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1562 to return \false, the colours will not be changed no matter what and only the
1563 font might.
1564
1565 This rather complicated logic is necessary in order to accommodate the
1566 different usage scenarios. The most common one is when all default attributes
1567 are used and in this case, nothing should be inherited as in modern GUIs
1568 different controls use different fonts (and colours) than their siblings so
1569 they can't inherit the same value from the parent. However it was also deemed
1570 desirable to allow to simply change the attributes of all children at once by
1571 just changing the font or colour of their common parent, hence in this case we
1572 do inherit the parents attributes.

1795
1796 Moves this window in the tab navigation order after the specified \arg{win}.
1797 This means that when the user presses \texttt{TAB} key on that other window,
1798 the focus switches to this window.
1799
1800 Default tab order is the same as creation order, this function and
1801 \helpref{MoveBeforeInTabOrder()}{wxwindowmovebeforeintaborder} allow to change

1819 \membersection{wxWindow::Navigate}\label{wxwindownavigate}
1820
1821 \func{bool}{Navigate}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
1822
1823 Performs a keyboard navigation action starting from this window. This method is
1824 equivalent to calling \helpref{NavigateIn()}{wxwindownavigatein} method on the
1825 parent window.
1826
1827 \wxheading{Parameters}

1837
1838 You may wish to call this from a text control custom keypress handler to do the default

1856
1857 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1858 function allows to retrieve the effective id of the latter control from the id
1859 of the former. This is useful for example to find the control following its
1860 \helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the

2446 \wxheading{Remarks}
2447
2448 An event handler is an object that is capable of processing the events
2449 sent to a window. By default, the window is its own event handler, but
2450 an application may wish to substitute another, for example to allow
2451 central implementation of event-handling for a variety of different
2452 window classes.
2453
2454 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2455 an application to set up a chain of event handlers, where an event not handled by one event handler is
2456 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2457 remove the event handler.

2521 will receive a hotkey event. It will receive the event even if the application is in the background
2522 and does not have the input focus because the user is working with some other application.

2726 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2727
2728 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2729
2730 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2731 be called automatically when the window is resized. Please note that this only
2732 happens for the windows usually used to contain children, namely
2733 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2734 (and the classes deriving from them).
2735
2736 This method is called implicitly by
2737 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2738 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2739 manually or otherwise the window layout won't be correctly updated when its
2740 size changes.
2741

2753
2754 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2755
2756 Sets the background colour of the window.
2757
2758 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2759 explanation of the difference between this method and
2760 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2761
2762 \wxheading{Parameters}
2763
2764 \docparam{colour}{The colour to be used as the background colour, pass
2765 {\tt wxNullColour} to reset to the default colour.}
2766
2767 \wxheading{Remarks}
2768
2769 The background colour is usually painted by the default\rtfsp
2770 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2771 under Windows and automatically under GTK.
2772
2773 Note that setting the background colour does not cause an immediate refresh, so you
2774 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2775 calling this function.
2776
2777 Using this function will disable attempts to use themes for this
2778 window, if the system supports them. Use with care since usually the
2779 themes represent the appearance chosen by the user to be used for all
2780 applications on the system.

2793
2794 \func{virtual void}{SetBackgroundStyle}{\param{wxBackgroundStyle}{ style}}
2795
2796 Sets the background style of the window. The background style indicates
2797 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2798 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2799 application to implement (wxBG\_STYLE\_CUSTOM).
2800
2801 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2802 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2815
2816 This method is only implemented by ports which have support for
2817 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2818 container control code to give the native system a hint when
2819 doing TAB traversal. A call to this does not disable or change
2820 the effect of programmatically calling
2821 \helpref{wxWindow::SetFocus}{wxwindowsetfocus}.

2840
2841 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2842
2843 This sets the size of the window client area in pixels. Using this function to size a window
2844 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2845 worry about what dimensions the border or title bar have when trying to fit the window
2846 around panel items, for example.
2847
2848 \wxheading{Parameters}
2849
2850 \docparam{width}{The required client area width.}

2869 Sets the window to have the given layout constraints. The window
2870 will then own the object, and will take care of its deletion.
2871 If an existing layout constraints object is already owned by the
2872 window, it will be deleted.
2873
2874 \wxheading{Parameters}
2875
2876 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2877 constraints.}
2878
2879 \wxheading{Remarks}
2880
2881 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2882 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2883 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2884 sizer will have effect.

2937 \wxheading{Parameters}
2938
2939 \docparam{handler}{Specifies the handler to be set.}
2940
2941 \wxheading{Remarks}
2942
2943 An event handler is an object that is capable of processing the events
2944 sent to a window. By default, the window is its own event handler, but
2945 an application may wish to substitute another, for example to allow
2946 central implementation of event-handling for a variety of different
2947 window classes.
2948
2949 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
2950 since this sets up a chain of event handlers, where an event not handled by
2951 one event handler is handed to the next one in the chain.

2972 and Validate() methods will recursively descend into all children of the

2974 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2975 events are propagated upwards to the window parent recursively until a handler
2976 for them is found. Using this style allows to prevent them from being
2977 propagated beyond this window. Notice that wxDialog has this style on by
2978 default for the reasons explained in the
2979 \helpref{event processing overview}{eventprocessing}.}
2980 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2981 window from being used as an implicit parent for the dialogs which were
2982 created without a parent. It is useful for the windows which can disappear at
2983 any moment as creating children of such windows results in fatal problems.}
2984 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2985 button on the caption. When pressed, Windows will go into a context-sensitive
2986 help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an
2987 application window.
2988 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2989 these two styles are automatically turned of if this one is used.}
2990 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even

3014 This function is called by wxWidgets keyboard navigation code when the user
3015 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).

3026 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3027 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3028 explanations.
3029
3030 Please notice that the given font is \emph{not} automatically used for
3031 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
3032 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3263 Let's say you wish to display 50 lines of text, using the same font.
3264 The window is sized so that you can only see 16 lines at a time.
3265
3266 You would use:
3267
3268 {\small%
3269 \begin{verbatim}
3270 SetScrollbar(wxVERTICAL, 0, 16, 50);
3271 \end{verbatim}
3272 }
3273
3274 Note that with the window at this size, the thumb position can never go
3275 above 50 minus 16, or 34.
3276
3277 You can determine how many lines are currently visible by dividing the current view
3278 size by the character height in pixels.
3279
3280 When defining your own scrollbar behaviour, you will always need to recalculate
3281 the scrollbar settings when the window size changes. You could therefore put your
3282 scrollbar calculations and SetScrollbar
3283 call into a function named AdjustScrollbars, which can be called initially and also
3284 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3310
3311 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3312 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3313 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3314 value has to be adjusted when the window is resized, since the page size will have changed.
3315
3316 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3317 the thumb changes size to reflect the page size relative to the length of the document. When the
3318 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3319 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3320 disappear.
3321
3322 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3323 handling of pages and ranges.

3378
3379 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3380 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3381 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3382 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3383 and usually the scrollbar will be automatically hidden.

3526 to draw the windows' background instead if its own background drawing
3527 code. This does not always have any effect since the underlying platform
3528 obviously needs to support the notion of themes in user defined windows.
3529 One such platform is GTK+ where windows can have (very colourful) backgrounds
3530 defined by a user's selected theme.

3715 \func{virtual bool}{TransferDataFromWindow}{\void}
3716
3717 Transfers values from child controls to data areas specified by their validators. Returns
3718 {\tt false} if a transfer failed.
3719
3720 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3721 the method will also call TransferDataFromWindow() of all child windows.

3771 \membersection{wxWindow::Update}\label{wxwindowupdate}
3772
3773 \func{virtual void}{Update}{\void}
3774
3775 Calling this method immediately repaints the invalidated area of the window and
3776 all of its children recursively while this would usually only happen when the
3777 flow of control returns to the event loop.
3778 Notice that this function doesn't invalidate any area of the window so
3779 nothing happens if nothing has been invalidated (i.e. marked as requiring
3780 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3781 immediately redraw the window unconditionally.

3784 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3785
3786 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3787
3788 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3789 the window. The particular implementation depends on the window; for
3790 example a wxToolBar will send an update UI event for each toolbar button,
3791 and a wxFrame will send an update UI event for each menubar menu item.
3792 You can call this function from your application to ensure that your
3793 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3794 are concerned). This may be necessary if you have called
3795 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3796 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3797 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3798
3799 {\it flags} should be a bitlist of one or more of the following values.
3800
3801 \begin{verbatim}
3802 enum wxUpdateUI
3803 {
3804 wxUPDATE_UI_NONE = 0x0000, // No particular value
3805 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3806 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3807 };
3808 \end{verbatim}
3809
3810 If you are calling this function from an OnInternalIdle or OnIdle
3811 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3812 this tells the window to only update the UI elements that need
3813 to be updated in idle time. Some windows update their elements
3814 only when necessary, for example when a menu is about to be shown.
3815 The following is an example of how to call UpdateWindowUI from
3816 an idle function.
3817
3818 \begin{verbatim}
3819 void MyWindow::OnInternalIdle()
3820 {
3821 if (wxUpdateUIEvent::CanUpdate(this))
3822 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3823 }

3834
3835 \func{virtual bool}{Validate}{\void}
3836
3837 Validates the current values of the child controls using their validators.
3838
3839 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3840 the method will also call Validate() of all child windows.
3841
3842 \wxheading{Return value}
3843
3844 Returns {\tt false} if any of the validations failed.
