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.

285
286 \func{void}{Center}{\param{int}{ direction}}
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
295 A synonym for \helpref{CentreOnParent}{wxwindowcentreonparent}.
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.
318
319 \wxheading{See also}
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}.

348 \membersection{wxWindow::ClearBackground}\label{wxwindowclearbackground}
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.}
369
370 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
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}

381 }
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)
465 \end{verbatim}

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
527 to a list of windows to be deleted on idle time, when all the window's events
528 have been processed. This prevents problems with events being sent to non-existent

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

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}

733 \func{virtual void}{FitInside}{\void}
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

905 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
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.

1652 This method should be overridden to return \texttt{true} if this window has
1653 multiple pages. All standard class with multiple pages such as
1654 \helpref{wxNotebook}{wxnotebook}, \helpref{wxListbook}{wxlistbook} and
1655 \helpref{wxTreebook}{wxtreebook} already override it to return \texttt{true}
1656 and user-defined classes with similar behaviour should do it as well to allow
1657 the library to handle such windows appropriately.

1676 wxStaticText) and should show the parent window background.
1677
1678 This method is mostly used internally by the library itself and you normally
1679 shouldn't have to call it. You may, however, have to override it in your

1704 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1705
1706 \func{void}{InheritAttributes}{\void}
1707
1708 This function is (or should be, in case of custom controls) called during
1709 window creation to intelligently set up the window visual attributes, that is
1710 the font and the foreground and background colours.
1711
1712 By ``intelligently'' the following is meant: by default, all windows use their
1713 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1714 if some of the parents attributes are explicitly (that is, using
1715 \helpref{SetFont}{wxwindowsetfont} and not
1716 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1717 corresponding attribute hadn't been explicitly set for this window itself,
1718 then this window takes the same value as used by the parent. In addition, if
1719 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1720 to return \false, the colours will not be changed no matter what and only the
1721 font might.
1722
1723 This rather complicated logic is necessary in order to accommodate the
1724 different usage scenarios. The most common one is when all default attributes
1725 are used and in this case, nothing should be inherited as in modern GUIs
1726 different controls use different fonts (and colours) than their siblings so
1727 they can't inherit the same value from the parent. However it was also deemed
1728 desirable to allow to simply change the attributes of all children at once by
1729 just changing the font or colour of their common parent, hence in this case we
1730 do inherit the parents attributes.

2622
2623 An event handler is an object that is capable of processing the events
2624 sent to a window. By default, the window is its own event handler, but
2625 an application may wish to substitute another, for example to allow
2626 central implementation of event-handling for a variety of different
2627 window classes.
2628
2629 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2630 an application to set up a chain of event handlers, where an event not handled by one event handler is
2631 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2693 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2694
2695 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2696 will receive a hotkey event. It will receive the event even if the application is in the background
2697 and does not have the input focus because the user is working with some other application.

2707
2708 \docparam{virtualKeyCode}{The virtual key code of the hotkey.}
2709
2710 \wxheading{Return value}
2711
2712 {\tt true} if the hotkey was registered successfully. {\tt false} if some other application already registered a

2901 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2902
2903 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2904
2905 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2906 be called automatically when the window is resized. Please note that this only
2907 happens for the windows usually used to contain children, namely
2908 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2909 (and the classes deriving from them).
2910
2911 This method is called implicitly by
2912 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2913 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2914 manually or otherwise the window layout won't be correctly updated when its
2915 size changes.
2916

2930
2931 Sets the background colour of the window.
2932
2933 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2934 explanation of the difference between this method and
2935 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2936
2937 \wxheading{Parameters}
2938
2939 \docparam{colour}{The colour to be used as the background colour, pass
2940 {\tt wxNullColour} to reset to the default colour.}
2941
2942 \wxheading{Remarks}
2943
2944 The background colour is usually painted by the default\rtfsp
2945 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2946 under Windows and automatically under GTK.
2947
2948 Note that setting the background colour does not cause an immediate refresh, so you
2949 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2950 calling this function.
2951
2952 Using this function will disable attempts to use themes for this
2953 window, if the system supports them. Use with care since usually the
2954 themes represent the appearance chosen by the user to be used for all
2955 applications on the system.

2986
2987 This method is only implemented by ports which have support for
2988 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2989 container control code to give the native system a hint when
2990 doing TAB traversal. A call to this does not disable or change

3014 This sets the size of the window client area in pixels. Using this function to size a window
3015 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
3016 worry about what dimensions the border or title bar have when trying to fit the window
3017 around panel items, for example.

3109
3110 \docparam{handler}{Specifies the handler to be set.}
3111
3112 \wxheading{Remarks}
3113
3114 An event handler is an object that is capable of processing the events
3115 sent to a window. By default, the window is its own event handler, but
3116 an application may wish to substitute another, for example to allow
3117 central implementation of event-handling for a variety of different
3118 window classes.
3119
3120 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3121 since this sets up a chain of event handlers, where an event not handled by
3122 one event handler is handed to the next one in the chain.

3145 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command

3471 Let's say you wish to display 50 lines of text, using the same font.
3472 The window is sized so that you can only see 16 lines at a time.
3473
3474 You would use:
3475
3476 {\small%
3477 \begin{verbatim}
3478 SetScrollbar(wxVERTICAL, 0, 16, 50);
3479 \end{verbatim}
3480 }
3481
3482 Note that with the window at this size, the thumb position can never go
3483 above 50 minus 16, or 34.
3484
3485 You can determine how many lines are currently visible by dividing the current view
3486 size by the character height in pixels.
3487
3488 When defining your own scrollbar behaviour, you will always need to recalculate
3489 the scrollbar settings when the window size changes. You could therefore put your
3490 scrollbar calculations and SetScrollbar
3491 call into a function named AdjustScrollbars, which can be called initially and also
3492 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3518
3519 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3520 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3521 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3522 value has to be adjusted when the window is resized, since the page size will have changed.
3523
3524 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3525 the thumb changes size to reflect the page size relative to the length of the document. When the
3526 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3527 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3528 disappear.
3529
3530 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3531 handling of pages and ranges.

3586
3587 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3588 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3589 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3590 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3591 and usually the scrollbar will be automatically hidden.

3720 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
3721 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
3722 only the sizer will have effect.

3727 \func{void}{SetSizerAndFit}{\param{wxSizer* }{sizer}, \param{bool }{deleteOld=true}}
3728
3729 This method calls \helpref{SetSizer}{wxwindowsetsizer} and then
3730 \helpref{wxSizer::SetSizeHints}{wxsizersetsizehints} which sets the initial
3731 window size to the size needed to accommodate all sizer elements and sets the
3732 size hints which, if this window is a top level one, prevent the user from
3733 resizing it to be less than this minimial size.

3736 \membersection{wxWindow::SetThemeEnabled}\label{wxwindowsetthemeenabled}
3737
3738 \func{virtual void}{SetThemeEnabled}{\param{bool }{enable}}
3739
3740 This function tells a window if it should use the system's "theme" code
3741 to draw the windows' background instead if its own background drawing
3742 code. This does not always have any effect since the underlying platform
3743 obviously needs to support the notion of themes in user defined windows.
3744 One such platform is GTK+ where windows can have (very colourful) backgrounds
3745 defined by a user's selected theme.
3746
3747 Dialogs, notebook pages and the status bar have this flag set to true
3748 by default so that the default look and feel is simulated best.

3768 returns \true, otherwise returns \false and the window remains fully opaque.
3769 See also \helpref{CanSetTransparent}{wxwindowcansettransparent}.
3770
3771 The parameter \arg{alpha} is in the range $0..255$ where $0$ corresponds to a
3772 fully transparent window and $255$ to the fully opaque one. The constants
3773 \texttt{wxIMAGE\_ALPHA\_TRANSPARENT} and \texttt{wxIMAGE\_ALPHA\_OPAQUE} can be
3774 used.

3851 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3852
3853 This function can be called under all platforms but only does anything under
3854 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3855 exist in several sizes which correspond to the elements of wxWindowVariant
3856 enum:
3857 \begin{verbatim}
3858 enum wxWindowVariant
3859 {
3860 wxWINDOW_VARIANT_NORMAL, // Normal size
3861 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3862 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3863 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3864 };
3865 \end{verbatim}
3866
3867 By default the controls use the normal size, of course, but this function can
3868 be used to change this.

3876 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3877 forbids inheriting them from the parent window.
3878
3879 The base class version returns \false, but this method is overridden in
3880 \helpref{wxControl}{wxcontrol} where it returns \true.

3883 \membersection{wxWindow::Show}\label{wxwindowshow}
3884
3885 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}

3887 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3888 for a top level window if you want to bring it to top, although this is not
3889 needed if Show() is called immediately after the frame creation.
3890
3891 \wxheading{Parameters}
3892
3893 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3894
3895 \wxheading{Return value}

3909 \func{virtual bool}{ShowWithEffect}{\param{wxShowEffect }{effect}, \param{unsigned }{timeout = $0$}, \param{wxDirection }{dir = wxBOTTOM}}
3910
3911 This function shows a window, like \helpref{Show()}{wxwindowshow}, but using a
3912 special visual effect if possible.
3913
3914 Possible values for \arg{effect} are:
3915 \begin{twocollist}\itemsep=0pt
3916 \twocolitem{wxSHOW\_EFFECT\_ROLL}{Roll window effect}
3917 \twocolitem{wxSHOW\_EFFECT\_SLIDE}{Sliding window effect}
3918 \twocolitem{wxSHOW\_EFFECT\_BLEND}{Fade in or out effect}
3919 \twocolitem{wxSHOW\_EFFECT\_EXPAND}{Expanding or collapsing effect}
3920 \end{twocollist}
3921
3922 For the roll and slide effects the \arg{dir} parameter specifies the animation
3923 direction: it can be one of \texttt{wxTOP}, \texttt{wxBOTTOM}, \texttt{wxLEFT}
3924 or \texttt{wxRIGHT}. For the other effects, this parameter is unused.
3925
3926 The \arg{timeout} parameter specifies the time of the animation, in
3927 milliseconds. If the default value of $0$ is used, the default animation time
3928 for the current platform is used.
3929
3930 Currently this function is only implemented in wxMSW and does the same thing as
3931 Show() in the other ports.

4052 \membersection{wxWindow::Update}\label{wxwindowupdate}
4053
4054 \func{virtual void}{Update}{\void}
4055
4056 Calling this method immediately repaints the invalidated area of the window and
4057 all of its children recursively while this would usually only happen when the
4058 flow of control returns to the event loop.
4059 Notice that this function doesn't invalidate any area of the window so
4060 nothing happens if nothing has been invalidated (i.e. marked as requiring
4061 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
4062 immediately redraw the window unconditionally.
4063
4064
4065 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
4066
4067 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
4068
4069 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
4070 the window. The particular implementation depends on the window; for
4071 example a wxToolBar will send an update UI event for each toolbar button,
4072 and a wxFrame will send an update UI event for each menubar menu item.
4073 You can call this function from your application to ensure that your
4074 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
4075 are concerned). This may be necessary if you have called
4076 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
4077 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
4078 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
4079
4080 {\it flags} should be a bitlist of one or more of the following values.
4081
4082 \begin{verbatim}
4083 enum wxUpdateUI
4084 {
4085 wxUPDATE_UI_NONE = 0x0000, // No particular value
4086 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
4087 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
4088 };
4089 \end{verbatim}
4090
4091 If you are calling this function from an OnInternalIdle or OnIdle
4092 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
4093 this tells the window to only update the UI elements that need
4094 to be updated in idle time. Some windows update their elements
4095 only when necessary, for example when a menu is about to be shown.
4096 The following is an example of how to call UpdateWindowUI from
4097 an idle function.
4098
4099 \begin{verbatim}
4100 void MyWindow::OnInternalIdle()
4101 {
4102 if (wxUpdateUIEvent::CanUpdate(this))
4103 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);

4155 \helpref{GetClientSize}{wxwindowgetclientsize} return if this window had
4156 given window size. Components with $wxDefaultCoord$ value are left unchanged.
4157
4158 Note that the conversion is not always exact, it assumes that non-client area
4159 doesn't change and so doesn't take into account things like menu bar
4160 (un)wrapping or (dis)appearance of the scrollbars.
