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 sub-windows, 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
293 \func{void}{CenterOnParent}{\param{int}{ direction}}
294

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.

320
321 \helpref{wxWindow::Center}{wxwindowcenter}
322
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}}
359
360 \perlnote{In wxPerl this method returns a 2-element list instead of
361 modifying its parameters.}
362
363 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
364
365 Converts to screen coordinates from coordinates relative to this window.
366
367 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
368 a screen coordinate will be passed out.}

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
377 \indented{2cm}{\begin{twocollist}

382
383 \membersection{wxWindow::ClientToWindowSize}\label{wxwindowclienttowindowsize}
384
385 \func{virtual wxSize}{ClientToWindowSize}{\param{const wxSize\&}{ size}}
386
387 Converts client area size \arg{size} to corresponding window size. In other
388 words, the returned value is what would \helpref{GetSize}{wxwindowgetsize}
389 return if this window had client area of given size.
390 Components with $wxDefaultCoord$ value are left unchanged.
391
392 Note that the conversion is not always exact, it assumes that non-client area
393 doesn't change and so doesn't take into account things like menu bar
394 (un)wrapping or (dis)appearance of the scrollbars.

400
401 \membersection{wxWindow::Close}\label{wxwindowclose}
402
403 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
404
405 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
406 handler usually tries to close the window. It doesn't close the window itself,
407 however.
408
409 \wxheading{Parameters}
410
411 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
412 of this window, {\tt true} if it cannot.}
413
414 \wxheading{Remarks}
415
416 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
417 an opportunity for the window to choose whether to destroy the window.
418 Usually it is only used with the top level windows (wxFrame and wxDialog
419 classes) as the others are not supposed to have any special OnClose() logic.
420
421 The close handler should check whether the window is being deleted forcibly,
422 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
423 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
424
425 {\it Note} that calling Close does not guarantee that the window will be
426 destroyed; but it provides a way to simulate a manual close of a window, which
427 may or may not be implemented by destroying the window. The default
428 implementation of wxDialog::OnCloseWindow does not necessarily delete the
429 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
430 the appropriate button event handler and may do anything at all.
431
432 To guarantee that the window will be destroyed, call
433 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

443
444 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
445
446 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
447
448 Converts a point or size from dialog units to pixels.
449
450 For the x dimension, the dialog units are multiplied by the average character width
451 and then divided by 4.
452
453 For the y dimension, the dialog units are multiplied by the average character height
454 and then divided by 8.
455
456 \wxheading{Remarks}
457
458 Dialog units are used for maintaining a dialog's proportions even if the font changes.
459
460 You can also use these functions programmatically. A convenience macro is defined:
461
462 {\small
463 \begin{verbatim}
464 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

523
524 Destroys the window safely. Use this function instead of the delete operator, since
525 different window classes can be destroyed differently. Frames and dialogs
526 are not destroyed immediately when this function is called -- they are added

717
718 Sizes the window so that it fits around its subwindows. This function won't do
719 anything if there are no subwindows and will only really work correctly if
720 sizers are used for the subwindows layout. Also, if the window has exactly one
721 subwindow it is better (faster and the result is more precise as Fit adds some
722 margin to account for fuzziness of its calculations) to call
723
724 \begin{verbatim}

734
735 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
736 of a window. Mainly useful with scrolled windows to reset scrollbars after
737 sizing changes that do not trigger a size event, and/or scrolled windows without
738 an interior sizer. This function similarly won't do anything if there are no
739 subwindows.
740
741
742 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
743
744 \func{virtual void}{Freeze}{\void}
745
746 Freezes the window or, in other words, prevents any updates from taking place
747 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
748 be called to reenable window redrawing. Calls to these two functions may be
749 nested but to ensure that the window is properly repainted again, you must thaw
750 it exactly as many times as you froze it.
751
752 This method is useful for visual appearance optimization (for example, it
753 is a good idea to use it before doing many large text insertions in a row into
754 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
755 controls so it is mostly just a hint to wxWidgets and not a mandatory

906
907 Returns the default font and colours which are used by the control. This is
908 useful if you want to use the same font or colour in your own control as in a
909 standard control -- which is a much better idea than hard coding specific
910 colours or fonts which might look completely out of place on the users
911 system, especially if it uses themes.
912
913 The \arg{variant} parameter is only relevant under Mac currently and is
914 ignore under other platforms. Under Mac, it will change the size of the
915 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
916 for more about this.
917
918 This static method is ``overridden'' in many derived classes and so calling,
919 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
920 return the values appropriate for a button which will be normally different
921 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
922
923 The \texttt{wxVisualAttributes} structure has at least the fields
924 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
925 if it was not possible to determine the default control appearance or,
926 especially for the background colour, if the field doesn't make sense as is
927 the case for \texttt{colBg} for the controls with themed background.

1001 Currently this is the same as calling
1002 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
1003
1004 One advantage of using this function compared to the static version is that
1005 the call is automatically dispatched to the correct class (as usual with
1006 virtual functions) and you don't have to specify the class name explicitly.
1007
1008 The other one is that in the future this function could return different
1009 results, for example it might return a different font for an ``Ok'' button
1010 than for a generic button if the users GUI is configured to show such buttons
1011 in bold font. Of course, the down side is that it is impossible to call this
1012 function without actually having an object to apply it to whereas the static
1013 version can be used without having to create an object first.

1663 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1664
1665 \func{void}{InheritAttributes}{\void}
1666
1667 This function is (or should be, in case of custom controls) called during
1668 window creation to intelligently set up the window visual attributes, that is
1669 the font and the foreground and background colours.
1670
1671 By ``intelligently'' the following is meant: by default, all windows use their
1672 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1673 if some of the parents attributes are explicitly (that is, using
1674 \helpref{SetFont}{wxwindowsetfont} and not
1675 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1676 corresponding attribute hadn't been explicitly set for this window itself,
1677 then this window takes the same value as used by the parent. In addition, if
1678 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1679 to return \false, the colours will not be changed no matter what and only the
1680 font might.
1681
1682 This rather complicated logic is necessary in order to accommodate the
1683 different usage scenarios. The most common one is when all default attributes
1684 are used and in this case, nothing should be inherited as in modern GUIs
1685 different controls use different fonts (and colours) than their siblings so
1686 they can't inherit the same value from the parent. However it was also deemed
1687 desirable to allow to simply change the attributes of all children at once by
1688 just changing the font or colour of their common parent, hence in this case we
1689 do inherit the parents attributes.

2580 \wxheading{Remarks}
2581
2582 An event handler is an object that is capable of processing the events
2583 sent to a window. By default, the window is its own event handler, but
2584 an application may wish to substitute another, for example to allow
2585 central implementation of event-handling for a variety of different
2586 window classes.
2587
2588 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2589 an application to set up a chain of event handlers, where an event not handled by one event handler is
2590 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2591 remove the event handler.

2863
2864 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2865 be called automatically when the window is resized. Please note that this only
2866 happens for the windows usually used to contain children, namely
2867 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2868 (and the classes deriving from them).
2869
2870 This method is called implicitly by
2871 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2872 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2873 manually or otherwise the window layout won't be correctly updated when its
2874 size changes.
2875

2887
2888 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2889
2890 Sets the background colour of the window.
2891
2892 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2893 explanation of the difference between this method and

2896 \wxheading{Parameters}
2897
2898 \docparam{colour}{The colour to be used as the background colour, pass
2899 {\tt wxNullColour} to reset to the default colour.}
2900
2901 \wxheading{Remarks}
2902
2903 The background colour is usually painted by the default\rtfsp
2904 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2905 under Windows and automatically under GTK.
2906
2907 Note that setting the background colour does not cause an immediate refresh, so you
2908 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2909 calling this function.
2910
2911 Using this function will disable attempts to use themes for this
2912 window, if the system supports them. Use with care since usually the
2913 themes represent the appearance chosen by the user to be used for all
2914 applications on the system.

2945
2946 This method is only implemented by ports which have support for
2947 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2948 container control code to give the native system a hint when
2949 doing TAB traversal. A call to this does not disable or change
2950 the effect of programmatically calling

2972
2973 This sets the size of the window client area in pixels. Using this function to size a window
2974 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2975 worry about what dimensions the border or title bar have when trying to fit the window
2976 around panel items, for example.

2978 \wxheading{Parameters}
2979
2980 \docparam{width}{The required client area width.}

3001 If an existing layout constraints object is already owned by the
3002 window, it will be deleted.

3010
3011 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
3012 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
3013 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

3068
3069 \docparam{handler}{Specifies the handler to be set.}
3070
3071 \wxheading{Remarks}
3072
3073 An event handler is an object that is capable of processing the events
3074 sent to a window. By default, the window is its own event handler, but
3075 an application may wish to substitute another, for example to allow
3076 central implementation of event-handling for a variety of different
3077 window classes.
3078
3079 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3080 since this sets up a chain of event handlers, where an event not handled by
3081 one event handler is handed to the next one in the chain.

3104 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
3105 events are propagated upwards to the window parent recursively until a handler
3106 for them is found. Using this style allows to prevent them from being

3394 Let's say you wish to display 50 lines of text, using the same font.
3395 The window is sized so that you can only see 16 lines at a time.
3396
3397 You would use:
3398
3399 {\small%
3400 \begin{verbatim}
3401 SetScrollbar(wxVERTICAL, 0, 16, 50);
3402 \end{verbatim}
3403 }
3404
3405 Note that with the window at this size, the thumb position can never go
3406 above 50 minus 16, or 34.
3407
3408 You can determine how many lines are currently visible by dividing the current view
3409 size by the character height in pixels.
3410
3411 When defining your own scrollbar behaviour, you will always need to recalculate
3412 the scrollbar settings when the window size changes. You could therefore put your
3413 scrollbar calculations and SetScrollbar
3414 call into a function named AdjustScrollbars, which can be called initially and also
3415 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3441
3442 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3443 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3444 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3445 value has to be adjusted when the window is resized, since the page size will have changed.
3446
3447 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3448 the thumb changes size to reflect the page size relative to the length of the document. When the
3449 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3450 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3451 disappear.
3452
3453 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3454 handling of pages and ranges.

3510 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3511 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3512 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3513 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3514 and usually the scrollbar will be automatically hidden.

3775
3776 This function can be called under all platforms but only does anything under
3777 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3778 exist in several sizes which correspond to the elements of wxWindowVariant
3779 enum:
3780 \begin{verbatim}
3781 enum wxWindowVariant
3782 {
3783 wxWINDOW_VARIANT_NORMAL, // Normal size
3784 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3785 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3786 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3787 };
3788 \end{verbatim}

3790 By default the controls use the normal size, of course, but this function can
3791 be used to change this.

3810 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3811 for a top level window if you want to bring it to top, although this is not
3812 needed if Show() is called immediately after the frame creation.
3813
3814 \wxheading{Parameters}
3815
3816 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3817
3818 \wxheading{Return value}

3832 \func{virtual bool}{ShowWithEffect}{\param{wxShowEffect }{effect}, \param{unsigned }{timeout = $0$}, \param{wxDirection }{dir = wxBOTTOM}}
3833
3834 This function shows a window, like \helpref{Show()}{wxwindowshow}, but using a
3835 special visual effect if possible.
3836
3837 Possible values for \arg{effect} are:
3838 \begin{twocollist}\itemsep=0pt
3839 \twocolitem{wxSHOW\_EFFECT\_ROLL}{Roll window effect}
3840 \twocolitem{wxSHOW\_EFFECT\_SLIDE}{Sliding window effect}
3841 \twocolitem{wxSHOW\_EFFECT\_BLEND}{Fade in or out effect}
3842 \twocolitem{wxSHOW\_EFFECT\_EXPAND}{Expanding or collapsing effect}
3843 \end{twocollist}
3844
3845 For the roll and slide effects the \arg{dir} parameter specifies the animation
3846 direction: it can be one of \texttt{wxTOP}, \texttt{wxBOTTOM}, \texttt{wxLEFT}
3847 or \texttt{wxRIGHT}. For the other effects, this parameter is unused.
3848
3849 The \arg{timeout} parameter specifies the time of the animation, in
3850 milliseconds. If the default value of $0$ is used, the default animation time
3851 for the current platform is used.
3852
3853 Currently this function is only implemented in wxMSW and does the same thing as
3854 Show() in the other ports.

3975 \membersection{wxWindow::Update}\label{wxwindowupdate}
3976
3977 \func{virtual void}{Update}{\void}
3978
3979 Calling this method immediately repaints the invalidated area of the window and
3980 all of its children recursively while this would usually only happen when the
3981 flow of control returns to the event loop.
3982 Notice that this function doesn't invalidate any area of the window so
3983 nothing happens if nothing has been invalidated (i.e. marked as requiring
3984 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3985 immediately redraw the window unconditionally.
3986
3987
3988 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3989
3990 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3991
3992 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3993 the window. The particular implementation depends on the window; for
3994 example a wxToolBar will send an update UI event for each toolbar button,
3995 and a wxFrame will send an update UI event for each menubar menu item.
3996 You can call this function from your application to ensure that your
3997 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3998 are concerned). This may be necessary if you have called
3999 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
4000 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
4001 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
4002
4003 {\it flags} should be a bitlist of one or more of the following values.
4004
4005 \begin{verbatim}
4006 enum wxUpdateUI
4007 {
4008 wxUPDATE_UI_NONE = 0x0000, // No particular value
4009 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
4010 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
4011 };
4012 \end{verbatim}
4013
4014 If you are calling this function from an OnInternalIdle or OnIdle
4015 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
4016 this tells the window to only update the UI elements that need
4017 to be updated in idle time. Some windows update their elements
4018 only when necessary, for example when a menu is about to be shown.
4019 The following is an example of how to call UpdateWindowUI from
4020 an idle function.
4021
4022 \begin{verbatim}
4023 void MyWindow::OnInternalIdle()
4024 {
4025 if (wxUpdateUIEvent::CanUpdate(this))
4026 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

4078 \helpref{GetClientSize}{wxwindowgetclientsize} return if this window had
4079 given window size. Components with $wxDefaultCoord$ value are left unchanged.
4080
4081 Note that the conversion is not always exact, it assumes that non-client area
4082 doesn't change and so doesn't take into account things like menu bar
4083 (un)wrapping or (dis)appearance of the scrollbars.
