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
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.

287
288 A synonym for \helpref{Centre}{wxwindowcentre}.
289
290
291 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}
292

296
297
298 \membersection{wxWindow::Centre}\label{wxwindowcentre}
299
300 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
301
302 Centres the window.
303
304 \wxheading{Parameters}
305
306 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
307 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
308 if you want to center the window on the entire screen and not on its
309 parent window.}
310
311 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
312 (it has no effect).
313
314 \wxheading{Remarks}
315
316 If the window is a top level one (i.e. doesn't have a parent), it will be
317 centered relative to the screen anyhow.

323
324 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
325
326 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
327
328 Centres the window on its parent. This is a more readable synonym for
329 \helpref{Centre}{wxwindowcentre}.
330
331 \wxheading{Parameters}
332
333 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
334 or {\tt wxBOTH}.}
335
336 \wxheading{Remarks}
337
338 This methods provides for a way to center top level windows over their
339 parents instead of the entire screen. If there is no parent or if the
340 window is not a top level window, then behaviour is the same as
341 \helpref{wxWindow::Centre}{wxwindowcentre}.

349
350 \func{void}{ClearBackground}{\void}
351
352 Clears the window by filling it with the current background colour. Does not
353 cause an erase background event to be generated.
354
355
356 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
357
358 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}

361 modifying its parameters.}
362
363 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}

371 a screen coordinate will be passed out.}
372
373 \docparam{pt}{The client position for the second form of the function.}
374
375 \pythonnote{In place of a single overloaded method name, wxPython
376 implements the following methods:\par

383
384 \membersection{wxWindow::Close}\label{wxwindowclose}
385
386 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
387
388 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
389 handler usually tries to close the window. It doesn't close the window itself,
390 however.
391
392 \wxheading{Parameters}
393
394 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
395 of this window, {\tt true} if it cannot.}
396
397 \wxheading{Remarks}
398
399 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
400 an opportunity for the window to choose whether to destroy the window.
401 Usually it is only used with the top level windows (wxFrame and wxDialog
402 classes) as the others are not supposed to have any special OnClose() logic.
403
404 The close handler should check whether the window is being deleted forcibly,
405 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
406 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
407
408 {\it Note} that calling Close does not guarantee that the window will be
409 destroyed; but it provides a way to simulate a manual close of a window, which
410 may or may not be implemented by destroying the window. The default
411 implementation of wxDialog::OnCloseWindow does not necessarily delete the
412 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
413 the appropriate button event handler and may do anything at all.
414
415 To guarantee that the window will be destroyed, call
416 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

426
427 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
428
429 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
430
431 Converts a point or size from dialog units to pixels.
432
433 For the x dimension, the dialog units are multiplied by the average character width
434 and then divided by 4.
435
436 For the y dimension, the dialog units are multiplied by the average character height
437 and then divided by 8.
438
439 \wxheading{Remarks}
440
441 Dialog units are used for maintaining a dialog's proportions even if the font changes.
442

508 different window classes can be destroyed differently. Frames and dialogs
509 are not destroyed immediately when this function is called -- they are added
510 to a list of windows to be deleted on idle time, when all the window's events
511 have been processed. This prevents problems with events being sent to non-existent
512 windows.

552 Does the window-specific updating after processing the update event.
553 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
554 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
555 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
556 implements this function as follows:
557
558 \begin{verbatim}
559 // do the window-specific processing after processing the update event
560 void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
561 {

699
700 Sizes the window so that it fits around its subwindows. This function won't do
701 anything if there are no subwindows and will only really work correctly if
702 sizers are used for the subwindows layout. Also, if the window has exactly one
703 subwindow it is better (faster and the result is more precise as Fit adds some
704 margin to account for fuzziness of its calculations) to call
705
706 \begin{verbatim}
707 window->SetClientSize(child->GetSize());

712
713 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}

716
717 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
718 of a window. Mainly useful with scrolled windows to reset scrollbars after
719 sizing changes that do not trigger a size event, and/or scrolled windows without
720 an interior sizer. This function similarly won't do anything if there are no
721 subwindows.
722
723
724 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

726 \func{virtual void}{Freeze}{\void}
727
728 Freezes the window or, in other words, prevents any updates from taking place
729 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
730 be called to reenable window redrawing. Calls to these two functions may be
731 nested but to ensure that the window is properly repainted again, you must thaw
732 it exactly as many times as you froze it.
733
734 This method is useful for visual appearance optimization (for example, it
735 is a good idea to use it before doing many large text insertions in a row into
736 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
737 controls so it is mostly just a hint to wxWidgets and not a mandatory

888
889 Returns the default font and colours which are used by the control. This is
890 useful if you want to use the same font or colour in your own control as in a
891 standard control -- which is a much better idea than hard coding specific
892 colours or fonts which might look completely out of place on the users
893 system, especially if it uses themes.
894
895 The \arg{variant} parameter is only relevant under Mac currently and is
896 ignore under other platforms. Under Mac, it will change the size of the
897 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
898 for more about this.
899
900 This static method is ``overridden'' in many derived classes and so calling,
901 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
902 return the values appropriate for a button which will be normally different
903 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
904
905 The \texttt{wxVisualAttributes} structure has at least the fields
906 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
907 if it was not possible to determine the default control appearance or,
908 especially for the background colour, if the field doesn't make sense as is
909 the case for \texttt{colBg} for the controls with themed background.

983 Currently this is the same as calling
984 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
985
986 One advantage of using this function compared to the static version is that
987 the call is automatically dispatched to the correct class (as usual with
988 virtual functions) and you don't have to specify the class name explicitly.
989
990 The other one is that in the future this function could return different
991 results, for example it might return a different font for an ``Ok'' button
992 than for a generic button if the users GUI is configured to show such buttons
993 in bold font. Of course, the down side is that it is impossible to call this
994 function without actually having an object to apply it to whereas the static
995 version can be used without having to create an object first.

1616
1617 \func{void}{InheritAttributes}{\void}
1618
1619 This function is (or should be, in case of custom controls) called during
1620 window creation to intelligently set up the window visual attributes, that is
1621 the font and the foreground and background colours.
1622
1623 By ``intelligently'' the following is meant: by default, all windows use their
1624 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1625 if some of the parents attributes are explicitly (that is, using
1626 \helpref{SetFont}{wxwindowsetfont} and not
1627 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1628 corresponding attribute hadn't been explicitly set for this window itself,
1629 then this window takes the same value as used by the parent. In addition, if
1630 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1631 to return \false, the colours will not be changed no matter what and only the
1632 font might.
1633
1634 This rather complicated logic is necessary in order to accommodate the
1635 different usage scenarios. The most common one is when all default attributes

1637 different controls use different fonts (and colours) than their siblings so
1638 they can't inherit the same value from the parent. However it was also deemed
1639 desirable to allow to simply change the attributes of all children at once by
1640 just changing the font or colour of their common parent, hence in this case we
1641 do inherit the parents attributes.

2533 An event handler is an object that is capable of processing the events

2536 central implementation of event-handling for a variety of different
2537 window classes.
2538
2539 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2811 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2812
2813 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2814
2815 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2816 be called automatically when the window is resized. Please note that this only
2817 happens for the windows usually used to contain children, namely
2818 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2819 (and the classes deriving from them).
2820
2821 This method is called implicitly by
2822 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2823 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2824 manually or otherwise the window layout won't be correctly updated when its
2825 size changes.
2826

2838
2839 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2840
2841 Sets the background colour of the window.
2842
2843 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2844 explanation of the difference between this method and
2845 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2846
2847 \wxheading{Parameters}
2848
2849 \docparam{colour}{The colour to be used as the background colour, pass
2850 {\tt wxNullColour} to reset to the default colour.}
2851
2852 \wxheading{Remarks}
2853
2854 The background colour is usually painted by the default\rtfsp
2855 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2856 under Windows and automatically under GTK.
2857
2858 Note that setting the background colour does not cause an immediate refresh, so you
2859 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2860 calling this function.
2861
2862 Using this function will disable attempts to use themes for this
2863 window, if the system supports them. Use with care since usually the
2864 themes represent the appearance chosen by the user to be used for all
2865 applications on the system.

2896
2897 This method is only implemented by ports which have support for
2898 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2899 container control code to give the native system a hint when
2900 doing TAB traversal. A call to this does not disable or change
2901 the effect of programmatically calling

2923
2924 This sets the size of the window client area in pixels. Using this function to size a window
2925 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2926 worry about what dimensions the border or title bar have when trying to fit the window
2927 around panel items, for example.
2928
2929 \wxheading{Parameters}
2930
2931 \docparam{width}{The required client area width.}

2961
2962 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2963 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2964 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

3019
3020 \docparam{handler}{Specifies the handler to be set.}
3021
3022 \wxheading{Remarks}
3023
3024 An event handler is an object that is capable of processing the events
3025 sent to a window. By default, the window is its own event handler, but
3026 an application may wish to substitute another, for example to allow
3027 central implementation of event-handling for a variety of different
3028 window classes.
3029
3030 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3031 since this sets up a chain of event handlers, where an event not handled by
3032 one event handler is handed to the next one in the chain.

3053 and Validate() methods will recursively descend into all children of the

3055 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
3056 events are propagated upwards to the window parent recursively until a handler
3057 for them is found. Using this style allows to prevent them from being
3058 propagated beyond this window. Notice that wxDialog has this style on by
3059 default for the reasons explained in the
3060 \helpref{event processing overview}{eventprocessing}.}
3061 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
3062 window from being used as an implicit parent for the dialogs which were
3063 created without a parent. It is useful for the windows which can disappear at
3064 any moment as creating children of such windows results in fatal problems.}

3094
3095 This function is called by wxWidgets keyboard navigation code when the user
3096 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
3097 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

3107 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3108 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3109 explanations.
3110
3111 Please notice that the given font is \emph{not} automatically used for
3112 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
3113 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3211
3212 A {\it smart} SetSize that will fill in default size components with the
3213 window's {\it best} size values. Also sets the window's minsize to
3214 the value passed in for use with sizers. This means that if a full or
3215 partial size is passed to this function then the sizers will use that
3216 size instead of the results of GetBestSize to determine the minimum
3217 needs of the window for layout.
3218
3219 Most controls will use this to set their initial size, and their min
3220 size to the passed in value (if any.)

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

3391
3392 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3393 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3394 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3395 value has to be adjusted when the window is resized, since the page size will have changed.
3396
3397 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3398 the thumb changes size to reflect the page size relative to the length of the document. When the
3399 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3400 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3401 disappear.
3402
3403 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3404 handling of pages and ranges.

3460 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3461 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3462 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3463 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3464 and usually the scrollbar will be automatically hidden.

3707 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
3708 need to be be called after changing the others for the change to take place
3709 immediately.

3721
3722 This function can be called under all platforms but only does anything under
3723 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3724 exist in several sizes which correspond to the elements of wxWindowVariant
3725 enum:
3726 \begin{verbatim}
3727 enum wxWindowVariant
3728 {
3729 wxWINDOW_VARIANT_NORMAL, // Normal size
3730 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3731 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3732 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3733 };
3734 \end{verbatim}
3735
3736 By default the controls use the normal size, of course, but this function can
3737 be used to change this.

3745 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3746 forbids inheriting them from the parent window.

3752 \membersection{wxWindow::Show}\label{wxwindowshow}
3753
3754 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3755
3756 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3757 for a top level window if you want to bring it to top, although this is not
3758 needed if Show() is called immediately after the frame creation.
3759
3760 \wxheading{Parameters}
3761
3762 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3763
3764 \wxheading{Return value}
3765
3766 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3767 done because it already was in the requested state.

3778 \func{virtual bool}{ShowWithEffect}{\param{wxShowEffect }{effect}, \param{unsigned }{timeout = $0$}, \param{wxDirection }{dir = wxBOTTOM}}
3779
3780 This function shows a window, like \helpref{Show()}{wxwindowshow}, but using a
3781 special visual effect if possible.
3782
3783 Possible values for \arg{effect} are:
3784 \begin{twocollist}\itemsep=0pt
3785 \twocolitem{wxSHOW\_EFFECT\_ROLL}{Roll window effect}
3786 \twocolitem{wxSHOW\_EFFECT\_SLIDE}{Sliding window effect}
3787 \twocolitem{wxSHOW\_EFFECT\_BLEND}{Fade in or out effect}
3788 \twocolitem{wxSHOW\_EFFECT\_EXPAND}{Expanding or collapsing effect}
3789 \end{twocollist}
3790
3791 For the roll and slide effects the \arg{dir} parameter specifies the animation
3792 direction: it can be one of \texttt{wxTOP}, \texttt{wxBOTTOM}, \texttt{wxLEFT}
3793 or \texttt{wxRIGHT}. For the other effects, this parameter is unused.
3794
3795 The \arg{timeout} parameter specifies the time of the animation, in
3796 milliseconds. If the default value of $0$ is used, the default animation time
3797 for the current platform is used.
3798
3799 Currently this function is only implemented in wxMSW and does the same thing as
3800 Show() in the other ports.

3921 \membersection{wxWindow::Update}\label{wxwindowupdate}
3922
3923 \func{virtual void}{Update}{\void}
3924
3925 Calling this method immediately repaints the invalidated area of the window and
3926 all of its children recursively while this would usually only happen when the
3927 flow of control returns to the event loop.
3928 Notice that this function doesn't invalidate any area of the window so
3929 nothing happens if nothing has been invalidated (i.e. marked as requiring
3930 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3931 immediately redraw the window unconditionally.
3932
3933
3934 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3935
3936 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3937
3938 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3939 the window. The particular implementation depends on the window; for
3940 example a wxToolBar will send an update UI event for each toolbar button,
3941 and a wxFrame will send an update UI event for each menubar menu item.
3942 You can call this function from your application to ensure that your
3943 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3944 are concerned). This may be necessary if you have called
3945 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3946 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3947 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3948
3949 {\it flags} should be a bitlist of one or more of the following values.
3950
3951 \begin{verbatim}
3952 enum wxUpdateUI
3953 {
3954 wxUPDATE_UI_NONE = 0x0000, // No particular value
3955 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3956 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3957 };
3958 \end{verbatim}
3959
3960 If you are calling this function from an OnInternalIdle or OnIdle
3961 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3962 this tells the window to only update the UI elements that need
3963 to be updated in idle time. Some windows update their elements
3964 only when necessary, for example when a menu is about to be shown.
3965 The following is an example of how to call UpdateWindowUI from
3966 an idle function.
3967
3968 \begin{verbatim}
3969 void MyWindow::OnInternalIdle()
3970 {
3971 if (wxUpdateUIEvent::CanUpdate(this))
3972 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3973 }
