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.}

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
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::AlwaysShowScrollbars}\label{wxwindowalwaysshowscrollbars}
223
224 \func{void}{AlwaysShowScrollbars}{\param{bool}{ hflag}, \param{bool}{ vflag}}
225
226 Call this function to force one or both scrollbars to be always shown, even if
227 the window is big enough to show its entire contents without scrolling.
228
229 \newsince{2.9.0}
230
231 \wxheading{Parameters}
232
233 \docparam{hflag}{Whether the horizontal scroll bar should always be visible.}
234
235 \docparam{vflag}{Whether the vertical scroll bar should always be visible.}
236
237 \wxheading{Remarks}
238
239 This function is currently only implemented under Mac/Carbon.
240
241
242 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
243
244 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
245
246 Sets the cached best size value.
247
248
249 \membersection{wxWindow::CanSetTransparent}\label{wxwindowcansettransparent}
250
251 \func{bool}{CanSetTransparent}{\void}
252
253 Returns \true if the system supports transparent windows and calling
254 \helpref{SetTransparent}{wxwindowsettransparent} may succeed. If this function
255 returns \false, transparent windows are definitely not supported by the current
256 system.
257
258
259 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
260
261 \func{virtual void}{CaptureMouse}{\void}
262
263 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
264 release the capture.
265
266 Note that wxWidgets maintains the stack of windows having captured the mouse
267 and when the mouse is released the capture returns to the window which had had
268 captured it previously and it is only really released if there were no previous
269 window. In particular, this means that you must release the mouse as many times
270 as you capture it, unless the window receives
271 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
272
273 Any application which captures the mouse in the beginning of some operation
274 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
275 and cancel this operation when it receives the event. The event handler must
276 not recapture mouse.

305 \membersection{wxWindow::Centre}\label{wxwindowcentre}
306
307 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
308
309 Centres the window.
310
311 \wxheading{Parameters}
312
313 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
314 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
315 if you want to center the window on the entire screen and not on its
316 parent window.}
317
318 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
319 (it has no effect).
320
321 \wxheading{Remarks}
322
323 If the window is a top level one (i.e. doesn't have a parent), it will be
324 centered relative to the screen anyhow.

331 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
332
333 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
334
335 Centres the window on its parent. This is a more readable synonym for
336 \helpref{Centre}{wxwindowcentre}.
337
338 \wxheading{Parameters}
339
340 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
341 or {\tt wxBOTH}.}
342
343 \wxheading{Remarks}
344
345 This methods provides for a way to center top level windows over their
346 parents instead of the entire screen. If there is no parent or if the
347 window is not a top level window, then behaviour is the same as
348 \helpref{wxWindow::Centre}{wxwindowcentre}.

355 \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
356
357 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
358
359 Centres the window on screen. This only works for top level windows -
360 otherwise, the window will still be centered on its parent.
361
362 \wxheading{Parameters}
363
364 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

408 \membersection{wxWindow::Close}\label{wxwindowclose}
409
410 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
411
412 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
413 handler usually tries to close the window. It doesn't close the window itself,
414 however.
415
416 \wxheading{Parameters}
417
418 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
419 of this window, {\tt true} if it cannot.}
420
421 \wxheading{Remarks}
422
423 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
424 an opportunity for the window to choose whether to destroy the window.
425 Usually it is only used with the top level windows (wxFrame and wxDialog
426 classes) as the others are not supposed to have any special OnClose() logic.
427
428 The close handler should check whether the window is being deleted forcibly,
429 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
430 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
431
432 {\it Note} that calling Close does not guarantee that the window will be
433 destroyed; but it provides a way to simulate a manual close of a window, which
434 may or may not be implemented by destroying the window. The default
435 implementation of wxDialog::OnCloseWindow does not necessarily delete the
436 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
437 the appropriate button event handler and may do anything at all.
438
439 To guarantee that the window will be destroyed, call
440 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

451 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
452
453 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
454
455 Converts a point or size from dialog units to pixels.
456
457 For the x dimension, the dialog units are multiplied by the average character width
458 and then divided by 4.
459
460 For the y dimension, the dialog units are multiplied by the average character height
461 and then divided by 8.
462
463 \wxheading{Remarks}
464
465 Dialog units are used for maintaining a dialog's proportions even if the font changes.
466
467 You can also use these functions programmatically. A convenience macro is defined:
468
469 {\small
470 \begin{verbatim}
471 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

532 different window classes can be destroyed differently. Frames and dialogs
533 are not destroyed immediately when this function is called -- they are added
534 to a list of windows to be deleted on idle time, when all the window's events
535 have been processed. This prevents problems with events being sent to non-existent
536 windows.
537
538 \wxheading{Return value}
539
540 {\tt true} if the window has either been successfully deleted, or it has been added
541 to the list of windows pending real deletion.

577 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
578 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
579 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
580 implements this function as follows:

722 \func{virtual void}{Fit}{\void}
723
724 Sizes the window so that it fits around its subwindows. This function won't do
725 anything if there are no subwindows and will only really work correctly if
726 sizers are used for the subwindows layout. Also, if the window has exactly one
727 subwindow it is better (faster and the result is more precise as Fit adds some
728 margin to account for fuzziness of its calculations) to call
729
730 \begin{verbatim}

741 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
742 of a window. Mainly useful with scrolled windows to reset scrollbars after
743 sizing changes that do not trigger a size event, and/or scrolled windows without
744 an interior sizer. This function similarly won't do anything if there are no
745 subwindows.

752 Freezes the window or, in other words, prevents any updates from taking place
753 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
754 be called to reenable window redrawing. Calls to these two functions may be
755 nested.
756
757 This method is useful for visual appearance optimization (for example, it
758 is a good idea to use it before doing many large text insertions in a row into
759 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
760 controls so it is mostly just a hint to wxWidgets and not a mandatory

911
912 Returns the default font and colours which are used by the control. This is
913 useful if you want to use the same font or colour in your own control as in a
914 standard control -- which is a much better idea than hard coding specific
915 colours or fonts which might look completely out of place on the users
916 system, especially if it uses themes.
917
918 The \arg{variant} parameter is only relevant under Mac currently and is
919 ignore under other platforms. Under Mac, it will change the size of the
920 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
921 for more about this.
922
923 This static method is ``overridden'' in many derived classes and so calling,
924 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
925 return the values appropriate for a button which will be normally different
926 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
927
928 The \texttt{wxVisualAttributes} structure has at least the fields
929 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
930 if it was not possible to determine the default control appearance or,
931 especially for the background colour, if the field doesn't make sense as is
932 the case for \texttt{colBg} for the controls with themed background.

1008
1009 One advantage of using this function compared to the static version is that
1010 the call is automatically dispatched to the correct class (as usual with
1011 virtual functions) and you don't have to specify the class name explicitly.
1012
1013 The other one is that in the future this function could return different
1014 results, for example it might return a different font for an ``Ok'' button
1015 than for a generic button if the users GUI is configured to show such buttons
1016 in bold font. Of course, the down side is that it is impossible to call this
1017 function without actually having an object to apply it to whereas the static
1018 version can be used without having to create an object first.

1618
1619 \func{void}{InheritAttributes}{\void}
1620
1621 This function is (or should be, in case of custom controls) called during
1622 window creation to intelligently set up the window visual attributes, that is
1623 the font and the foreground and background colours.
1624
1625 By ``intelligently'' the following is meant: by default, all windows use their
1626 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1627 if some of the parents attributes are explicitly (that is, using
1628 \helpref{SetFont}{wxwindowsetfont} and not
1629 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1630 corresponding attribute hadn't been explicitly set for this window itself,
1631 then this window takes the same value as used by the parent. In addition, if
1632 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1633 to return \false, the colours will not be changed no matter what and only the
1634 font might.
1635
1636 This rather complicated logic is necessary in order to accommodate the
1637 different usage scenarios. The most common one is when all default attributes
1638 are used and in this case, nothing should be inherited as in modern GUIs
1639 different controls use different fonts (and colours) than their siblings so
1640 they can't inherit the same value from the parent. However it was also deemed
1641 desirable to allow to simply change the attributes of all children at once by
1642 just changing the font or colour of their common parent, hence in this case we
1643 do inherit the parents attributes.

1882 Moves this window in the tab navigation order after the specified \arg{win}.
1883 This means that when the user presses \texttt{TAB} key on that other window,
1884 the focus switches to this window.
1885
1886 Default tab order is the same as creation order, this function and

1943 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1944 function allows to retrieve the effective id of the latter control from the id
1945 of the former. This is useful for example to find the control following its

2534 An event handler is an object that is capable of processing the events

2536 an application may wish to substitute another, for example to allow
2537 central implementation of event-handling for a variety of different
2538 window classes.
2539
2540 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2541 an application to set up a chain of event handlers, where an event not handled by one event handler is
2542 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2812 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2813
2814 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2815
2816 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2817 be called automatically when the window is resized. Please note that this only
2818 happens for the windows usually used to contain children, namely
2819 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2820 (and the classes deriving from them).
2821
2822 This method is called implicitly by
2823 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2824 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2825 manually or otherwise the window layout won't be correctly updated when its
2826 size changes.
2827

2839
2840 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2841
2842 Sets the background colour of the window.
2843
2844 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2845 explanation of the difference between this method and
2846 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2847
2848 \wxheading{Parameters}
2849
2850 \docparam{colour}{The colour to be used as the background colour, pass
2851 {\tt wxNullColour} to reset to the default colour.}
2852
2853 \wxheading{Remarks}
2854
2855 The background colour is usually painted by the default\rtfsp
2856 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2857 under Windows and automatically under GTK.
2858
2859 Note that setting the background colour does not cause an immediate refresh, so you
2860 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2861 calling this function.
2862
2863 Using this function will disable attempts to use themes for this
2864 window, if the system supports them. Use with care since usually the
2865 themes represent the appearance chosen by the user to be used for all
2866 applications on the system.

2897
2898 This method is only implemented by ports which have support for
2899 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2900 container control code to give the native system a hint when
2901 doing TAB traversal. A call to this does not disable or change
2902 the effect of programmatically calling

2924
2925 This sets the size of the window client area in pixels. Using this function to size a window
2926 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2927 worry about what dimensions the border or title bar have when trying to fit the window
2928 around panel items, for example.
2929
2930 \wxheading{Parameters}
2931
2932 \docparam{width}{The required client area width.}

2963 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2964 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2965 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

3020
3021 \docparam{handler}{Specifies the handler to be set.}
3022
3023 \wxheading{Remarks}
3024
3025 An event handler is an object that is capable of processing the events
3026 sent to a window. By default, the window is its own event handler, but
3027 an application may wish to substitute another, for example to allow
3028 central implementation of event-handling for a variety of different
3029 window classes.
3030
3031 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3032 since this sets up a chain of event handlers, where an event not handled by
3033 one event handler is handed to the next one in the chain.

3054 and Validate() methods will recursively descend into all children of the

3056 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
3057 events are propagated upwards to the window parent recursively until a handler
3058 for them is found. Using this style allows to prevent them from being
3059 propagated beyond this window. Notice that wxDialog has this style on by
3060 default for the reasons explained in the
3061 \helpref{event processing overview}{eventprocessing}.}
3062 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
3063 window from being used as an implicit parent for the dialogs which were
3064 created without a parent. It is useful for the windows which can disappear at
3065 any moment as creating children of such windows results in fatal problems.}

3070 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so

3095
3096 This function is called by wxWidgets keyboard navigation code when the user
3097 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
3098 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

3109 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3110 explanations.
3111
3112 Please notice that the given font is \emph{not} automatically used for
3113 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to

3212
3213 A {\it smart} SetSize that will fill in default size components with the
3214 window's {\it best} size values. Also sets the window's minsize to
3215 the value passed in for use with sizers. This means that if a full or
3216 partial size is passed to this function then the sizers will use that
3217 size instead of the results of GetBestSize to determine the minimum
3218 needs of the window for layout.
3219
3220 Most controls will use this to set their initial size, and their min
3221 size to the passed in value (if any.)

3344
3345 Let's say you wish to display 50 lines of text, using the same font.
3346 The window is sized so that you can only see 16 lines at a time.
3347
3348 You would use:
3349
3350 {\small%
3351 \begin{verbatim}
3352 SetScrollbar(wxVERTICAL, 0, 16, 50);
3353 \end{verbatim}
3354 }
3355
3356 Note that with the window at this size, the thumb position can never go
3357 above 50 minus 16, or 34.
3358
3359 You can determine how many lines are currently visible by dividing the current view
3360 size by the character height in pixels.
3361
3362 When defining your own scrollbar behaviour, you will always need to recalculate
3363 the scrollbar settings when the window size changes. You could therefore put your
3364 scrollbar calculations and SetScrollbar
3365 call into a function named AdjustScrollbars, which can be called initially and also
3366 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3392
3393 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3394 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3395 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3396 value has to be adjusted when the window is resized, since the page size will have changed.
3397
3398 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3399 the thumb changes size to reflect the page size relative to the length of the document. When the
3400 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3401 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3402 disappear.
3403
3404 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3405 handling of pages and ranges.

3461 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3462 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3463 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3464 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3465 and usually the scrollbar will be automatically hidden.

3719
3720 This function can be called under all platforms but only does anything under
3721 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3722 exist in several sizes which correspond to the elements of wxWindowVariant
3723 enum:
3724 \begin{verbatim}
3725 enum wxWindowVariant
3726 {
3727 wxWINDOW_VARIANT_NORMAL, // Normal size
3728 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3729 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3730 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3731 };
3732 \end{verbatim}
3733
3734 By default the controls use the normal size, of course, but this function can
3735 be used to change this.

3742 Return \true from here to allow the colours of this window to be changed by
3743 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3744 forbids inheriting them from the parent window.
3745
3746 The base class version returns \false, but this method is overridden in
3747 \helpref{wxControl}{wxcontrol} where it returns \true.

3750 \membersection{wxWindow::Show}\label{wxwindowshow}
3751
3752 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3753
3754 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3755 for a top level window if you want to bring it to top, although this is not
3756 needed if Show() is called immediately after the frame creation.
3757
3758 \wxheading{Parameters}
3759
3760 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3761
3762 \wxheading{Return value}
3763
3764 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3765 done because it already was in the requested state.

3790
3791 Turns the given \arg{flag} on if it's currently turned off and vice versa.
3792 This function cannot be used if the value of the flag is $0$ (which is often
3793 the case for default flags).

3868
3869 \func{virtual void}{Update}{\void}
3870
3871 Calling this method immediately repaints the invalidated area of the window and
3872 all of its children recursively while this would usually only happen when the
3873 flow of control returns to the event loop.
3874 Notice that this function doesn't invalidate any area of the window so
3875 nothing happens if nothing has been invalidated (i.e. marked as requiring
3876 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3877 immediately redraw the window unconditionally.
3878

3880 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3881
3882 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3883
3884 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3885 the window. The particular implementation depends on the window; for
3886 example a wxToolBar will send an update UI event for each toolbar button,
3887 and a wxFrame will send an update UI event for each menubar menu item.
3888 You can call this function from your application to ensure that your
3889 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3890 are concerned). This may be necessary if you have called
3891 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3892 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3893 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3894
3895 {\it flags} should be a bitlist of one or more of the following values.
3896
3897 \begin{verbatim}
3898 enum wxUpdateUI
3899 {
3900 wxUPDATE_UI_NONE = 0x0000, // No particular value
3901 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3902 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3903 };
3904 \end{verbatim}
3905
3906 If you are calling this function from an OnInternalIdle or OnIdle
3907 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3908 this tells the window to only update the UI elements that need
3909 to be updated in idle time. Some windows update their elements
3910 only when necessary, for example when a menu is about to be shown.
3911 The following is an example of how to call UpdateWindowUI from
3912 an idle function.
3913
3914 \begin{verbatim}
3915 void MyWindow::OnInternalIdle()
3916 {
3917 if (wxUpdateUIEvent::CanUpdate(this))
3918 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3919 }

3930

3934
3935 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3936 the method will also call Validate() of all child windows.
3937
3938 \wxheading{Return value}
