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.}

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

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::CanSetTransparent}\label{wxwindowcansettransparent}
230
231 \func{bool}{CanSetTransparent}{\void}
232
233 Returns \true if the system supports transparent windows and calling
234 \helpref{SetTransparent}{wxwindowsettransparent} may succeed. If this function
235 returns \false, transparent windows are definitely not supported by the current
236 system.
237
238
239 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
240
241 \func{virtual void}{CaptureMouse}{\void}
242
243 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
244 release the capture.
245
246 Note that wxWidgets maintains the stack of windows having captured the mouse
247 and when the mouse is released the capture returns to the window which had had
248 captured it previously and it is only really released if there were no previous
249 window. In particular, this means that you must release the mouse as many times
250 as you capture it, unless the window receives
251 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
252
253 Any application which captures the mouse in the beginning of some operation
254 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
255 and cancel this operation when it receives the event. The event handler must
256 not recapture mouse.

283
284
285 \membersection{wxWindow::Centre}\label{wxwindowcentre}
286
287 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
288
289 Centres the window.
290
291 \wxheading{Parameters}
292
293 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
294 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
295 if you want to center the window on the entire screen and not on its
296 parent window.}
297
298 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
299 (it has no effect).
300
301 \wxheading{Remarks}
302
303 If the window is a top level one (i.e. doesn't have a parent), it will be
304 centered relative to the screen anyhow.

311 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
312
313 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
314
315 Centres the window on its parent. This is a more readable synonym for
316 \helpref{Centre}{wxwindowcentre}.
317
318 \wxheading{Parameters}
319
320 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
321 or {\tt wxBOTH}.}
322
323 \wxheading{Remarks}
324
325 This methods provides for a way to center top level windows over their
326 parents instead of the entire screen. If there is no parent or if the
327 window is not a top level window, then behaviour is the same as
328 \helpref{wxWindow::Centre}{wxwindowcentre}.

336
337 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
338
339 Centres the window on screen. This only works for top level windows -
340 otherwise, the window will still be centered on its parent.
341
342 \wxheading{Parameters}
343
344 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

353
354 \func{void}{ClearBackground}{\void}
355
356 Clears the window by filling it with the current background colour. Does not
357 cause an erase background event to be generated.
358
359
360 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
361
362 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}

369 Converts to screen coordinates from coordinates relative to this window.
370
371 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
372 a screen coordinate will be passed out.}

387
388 \membersection{wxWindow::Close}\label{wxwindowclose}
389
390 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
391
392 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
393 handler usually tries to close the window. It doesn't close the window itself,
394 however.
395
396 \wxheading{Parameters}
397
398 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
399 of this window, {\tt true} if it cannot.}
400
401 \wxheading{Remarks}
402
403 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
404 an opportunity for the window to choose whether to destroy the window.
405 Usually it is only used with the top level windows (wxFrame and wxDialog
406 classes) as the others are not supposed to have any special OnClose() logic.
407
408 The close handler should check whether the window is being deleted forcibly,
409 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
410 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
411
412 {\it Note} that calling Close does not guarantee that the window will be
413 destroyed; but it provides a way to simulate a manual close of a window, which
414 may or may not be implemented by destroying the window. The default
415 implementation of wxDialog::OnCloseWindow does not necessarily delete the
416 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
417 the appropriate button event handler and may do anything at all.
418
419 To guarantee that the window will be destroyed, call
420 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

430
431 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
432
433 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
434
435 Converts a point or size from dialog units to pixels.
436
437 For the x dimension, the dialog units are multiplied by the average character width
438 and then divided by 4.
439
440 For the y dimension, the dialog units are multiplied by the average character height
441 and then divided by 8.
442
443 \wxheading{Remarks}
444
445 Dialog units are used for maintaining a dialog's proportions even if the font changes.
446
447 You can also use these functions programmatically. A convenience macro is defined:

512 different window classes can be destroyed differently. Frames and dialogs
513 are not destroyed immediately when this function is called -- they are added

515 have been processed. This prevents problems with events being sent to non-existent
516 windows.

557 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
558 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
559 act appropriately. For example, to allow frame and dialog title updating, wxWidgets

702 \func{virtual void}{Fit}{\void}
703
704 Sizes the window so that it fits around its subwindows. This function won't do
705 anything if there are no subwindows and will only really work correctly if
706 sizers are used for the subwindows layout. Also, if the window has exactly one
707 subwindow it is better (faster and the result is more precise as Fit adds some
708 margin to account for fuzziness of its calculations) to call
709
710 \begin{verbatim}

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

733 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
734 be called to reenable window redrawing. Calls to these two functions may be
735 nested.
736
737 This method is useful for visual appearance optimization (for example, it
738 is a good idea to use it before doing many large text insertions in a row into
739 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
740 controls so it is mostly just a hint to wxWidgets and not a mandatory

891
892 Returns the default font and colours which are used by the control. This is
893 useful if you want to use the same font or colour in your own control as in a
894 standard control -- which is a much better idea than hard coding specific
895 colours or fonts which might look completely out of place on the users
896 system, especially if it uses themes.
897
898 The \arg{variant} parameter is only relevant under Mac currently and is
899 ignore under other platforms. Under Mac, it will change the size of the
900 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
901 for more about this.
902
903 This static method is ``overridden'' in many derived classes and so calling,
904 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
905 return the values appropriate for a button which will be normally different
906 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
907
908 The \texttt{wxVisualAttributes} structure has at least the fields
909 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
910 if it was not possible to determine the default control appearance or,
911 especially for the background colour, if the field doesn't make sense as is
912 the case for \texttt{colBg} for the controls with themed background.

986 Currently this is the same as calling
987 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
988
989 One advantage of using this function compared to the static version is that
990 the call is automatically dispatched to the correct class (as usual with
991 virtual functions) and you don't have to specify the class name explicitly.
992
993 The other one is that in the future this function could return different
994 results, for example it might return a different font for an ``Ok'' button
995 than for a generic button if the users GUI is configured to show such buttons
996 in bold font. Of course, the down side is that it is impossible to call this
997 function without actually having an object to apply it to whereas the static
998 version can be used without having to create an object first.

1570
1571 \func{void}{InheritAttributes}{\void}
1572
1573 This function is (or should be, in case of custom controls) called during
1574 window creation to intelligently set up the window visual attributes, that is
1575 the font and the foreground and background colours.
1576
1577 By ``intelligently'' the following is meant: by default, all windows use their
1578 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1579 if some of the parents attributes are explicitly (that is, using
1580 \helpref{SetFont}{wxwindowsetfont} and not
1581 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1582 corresponding attribute hadn't been explicitly set for this window itself,
1583 then this window takes the same value as used by the parent. In addition, if
1584 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1585 to return \false, the colours will not be changed no matter what and only the
1586 font might.
1587
1588 This rather complicated logic is necessary in order to accommodate the
1589 different usage scenarios. The most common one is when all default attributes
1590 are used and in this case, nothing should be inherited as in modern GUIs
1591 different controls use different fonts (and colours) than their siblings so
1592 they can't inherit the same value from the parent. However it was also deemed
1593 desirable to allow to simply change the attributes of all children at once by
1594 just changing the font or colour of their common parent, hence in this case we
1595 do inherit the parents attributes.

1820 This means that when the user presses \texttt{TAB} key on that other window,
1821 the focus switches to this window.
1822
1823 Default tab order is the same as creation order, this function and

1880 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1881 function allows to retrieve the effective id of the latter control from the id
1882 of the former. This is useful for example to find the control following its

2470
2471 An event handler is an object that is capable of processing the events
2472 sent to a window. By default, the window is its own event handler, but
2473 an application may wish to substitute another, for example to allow
2474 central implementation of event-handling for a variety of different
2475 window classes.
2476
2477 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2478 an application to set up a chain of event handlers, where an event not handled by one event handler is
2479 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2480 remove the event handler.

2749 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2750
2751 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2752
2753 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2754 be called automatically when the window is resized. Please note that this only
2755 happens for the windows usually used to contain children, namely
2756 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2757 (and the classes deriving from them).
2758
2759 This method is called implicitly by
2760 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2761 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2762 manually or otherwise the window layout won't be correctly updated when its
2763 size changes.
2764
2765 \wxheading{Parameters}

2776
2777 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2778
2779 Sets the background colour of the window.
2780
2781 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2782 explanation of the difference between this method and
2783 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2784
2785 \wxheading{Parameters}
2786
2787 \docparam{colour}{The colour to be used as the background colour, pass
2788 {\tt wxNullColour} to reset to the default colour.}
2789
2790 \wxheading{Remarks}
2791
2792 The background colour is usually painted by the default\rtfsp
2793 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2794 under Windows and automatically under GTK.
2795
2796 Note that setting the background colour does not cause an immediate refresh, so you
2797 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2798 calling this function.
2799
2800 Using this function will disable attempts to use themes for this
2801 window, if the system supports them. Use with care since usually the
2802 themes represent the appearance chosen by the user to be used for all
2803 applications on the system.

2834
2835 This method is only implemented by ports which have support for
2836 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2837 container control code to give the native system a hint when
2838 doing TAB traversal. A call to this does not disable or change
2839 the effect of programmatically calling
2840 \helpref{wxWindow::SetFocus}{wxwindowsetfocus}.

2859
2860 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2861
2862 This sets the size of the window client area in pixels. Using this function to size a window
2863 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2864 worry about what dimensions the border or title bar have when trying to fit the window
2865 around panel items, for example.
2866
2867 \wxheading{Parameters}
2868
2869 \docparam{width}{The required client area width.}
2870

2889 will then own the object, and will take care of its deletion.
2890 If an existing layout constraints object is already owned by the
2891 window, it will be deleted.
2892
2893 \wxheading{Parameters}
2894
2895 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2896 constraints.}
2897
2898 \wxheading{Remarks}
2899
2900 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2901 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2902 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2903 sizer will have effect.

2956 \wxheading{Parameters}
2957
2958 \docparam{handler}{Specifies the handler to be set.}
2959
2960 \wxheading{Remarks}
2961
2962 An event handler is an object that is capable of processing the events
2963 sent to a window. By default, the window is its own event handler, but
2964 an application may wish to substitute another, for example to allow
2965 central implementation of event-handling for a variety of different
2966 window classes.
2967
2968 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
2969 since this sets up a chain of event handlers, where an event not handled by
2970 one event handler is handed to the next one in the chain.

2991 and Validate() methods will recursively descend into all children of the
2992 window if it has this style flag set.}
2993 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2994 events are propagated upwards to the window parent recursively until a handler
2995 for them is found. Using this style allows to prevent them from being
2996 propagated beyond this window. Notice that wxDialog has this style on by
2997 default for the reasons explained in the
2998 \helpref{event processing overview}{eventprocessing}.}
2999 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
3000 window from being used as an implicit parent for the dialogs which were
3001 created without a parent. It is useful for the windows which can disappear at
3002 any moment as creating children of such windows results in fatal problems.}
3003 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
3004 button on the caption. When pressed, Windows will go into a context-sensitive
3005 help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an
3006 application window.
3007 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
3008 these two styles are automatically turned of if this one is used.}
3009 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even

3032
3033 This function is called by wxWidgets keyboard navigation code when the user
3034 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
3035 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

3045 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3046 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3047 explanations.
3048
3049 Please notice that the given font is \emph{not} automatically used for
3050 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
3051 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3282 Let's say you wish to display 50 lines of text, using the same font.
3283 The window is sized so that you can only see 16 lines at a time.
3284
3285 You would use:
3286
3287 {\small%
3288 \begin{verbatim}
3289 SetScrollbar(wxVERTICAL, 0, 16, 50);
3290 \end{verbatim}
3291 }
3292
3293 Note that with the window at this size, the thumb position can never go
3294 above 50 minus 16, or 34.
3295
3296 You can determine how many lines are currently visible by dividing the current view
3297 size by the character height in pixels.
3298
3299 When defining your own scrollbar behaviour, you will always need to recalculate
3300 the scrollbar settings when the window size changes. You could therefore put your
3301 scrollbar calculations and SetScrollbar
3302 call into a function named AdjustScrollbars, which can be called initially and also
3303 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3329
3330 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3331 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3332 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3333 value has to be adjusted when the window is resized, since the page size will have changed.
3334
3335 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3336 the thumb changes size to reflect the page size relative to the length of the document. When the
3337 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3338 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3339 disappear.
3340
3341 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3342 handling of pages and ranges.

3397
3398 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3399 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3400 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3401 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3402 and usually the scrollbar will be automatically hidden.

3544 This function tells a window if it should use the system's "theme" code
3545 to draw the windows' background instead if its own background drawing
3546 code. This does not always have any effect since the underlying platform
3547 obviously needs to support the notion of themes in user defined windows.
3548 One such platform is GTK+ where windows can have (very colourful) backgrounds
3549 defined by a user's selected theme.

3727
3728 Turns the given \arg{flag} on if it's currently turned off and vice versa.
3729 This function cannot be used if the value of the flag is $0$ (which is often
3730 the case for default flags).

3805
3806 \func{virtual void}{Update}{\void}
3807
3808 Calling this method immediately repaints the invalidated area of the window and
3809 all of its children recursively while this would usually only happen when the
3810 flow of control returns to the event loop.
3811 Notice that this function doesn't invalidate any area of the window so
3812 nothing happens if nothing has been invalidated (i.e. marked as requiring
3813 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3814 immediately redraw the window unconditionally.

3817 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3818
3819 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3820
3821 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3822 the window. The particular implementation depends on the window; for
3823 example a wxToolBar will send an update UI event for each toolbar button,
3824 and a wxFrame will send an update UI event for each menubar menu item.
3825 You can call this function from your application to ensure that your
3826 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3827 are concerned). This may be necessary if you have called
3828 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3829 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3830 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3831
3832 {\it flags} should be a bitlist of one or more of the following values.
3833
3834 \begin{verbatim}
3835 enum wxUpdateUI
3836 {
3837 wxUPDATE_UI_NONE = 0x0000, // No particular value
3838 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3839 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3840 };
3841 \end{verbatim}
3842
3843 If you are calling this function from an OnInternalIdle or OnIdle
3844 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3845 this tells the window to only update the UI elements that need
3846 to be updated in idle time. Some windows update their elements
3847 only when necessary, for example when a menu is about to be shown.
3848 The following is an example of how to call UpdateWindowUI from
3849 an idle function.
3850
3851 \begin{verbatim}
3852 void MyWindow::OnInternalIdle()
3853 {
3854 if (wxUpdateUIEvent::CanUpdate(this))
3855 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3856 }
