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.

44 \wxheading{Window styles}
45
46 The following styles can apply to all windows, although they will not always make sense for a particular
47 window class or on all platforms.
48
49 \twocolwidtha{5cm}%
50 \begin{twocollist}\itemsep=0pt
51 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
52 for this style. }
53 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
54 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
55 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
56 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
57 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
58 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
59 events. Windows only.}
60 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
61 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
62 the window wants to get all char/key events for all keys - even for
63 keys like TAB or ENTER which are usually used for dialog navigation
64 and which wouldn't be generated without this style. If you need to
65 use this style in order to get the arrows or etc., but would still like
66 to have normal keyboard navigation take place, you should call
67 \helpref{Navigate}{wxwindownavigate} in response to the key events for
68 Tab and Shift-Tab.}
69 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
70 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
71 and no longer has an effect.}
72 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
73 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
74 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
75 disable them instead of hiding them when they are not needed (i.e. when the
76 size of the window is big enough to not require the scrollbars to navigate it).
77 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
78 nothing on the other platforms.}
79 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
80 repainted, then children being painted over them. Windows only.}
81 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
82 a complete redraw of the window whenever it is resized instead of redrawing
83 just the part of the window affected by resizing. Note that this was the
84 behaviour by default before 2.5.1 release and that if you experience redraw
85 problems with code which previously used to work you may want to try this.
86 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
87 done on other platforms.}

92 \wxheading{Extra window styles}
93
94 The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}.
95
96 \twocolwidtha{5cm}%
97 \begin{twocollist}\itemsep=0pt
98 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
99 only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
100 descend into all subwindows.}
101 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
102 parent window and so on recursively by default. Using this flag for the
103 given window allows to block this propagation at this window, i.e. prevent
104 the events from being propagated further upwards. Dialogs have this
105 flag on by default.}
106 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
107 be used with transient windows as otherwise there is the risk of creating a
108 dialog/frame with this window as a parent which would lead to a crash if the
109 parent is destroyed before the child.}
110 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
111 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
112 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
113 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

124 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
125
126 \func{}{wxWindow}{\void}
127
128 Default constructor.
129
130 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
131 \param{const wxPoint\& }{pos = wxDefaultPosition},
132 \param{const wxSize\& }{size = wxDefaultSize},
133 \param{long }{style = 0},
134 \param{const wxString\& }{name = wxPanelNameStr}}
135
136 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
137
138 \wxheading{Parameters}
139
140 \docparam{parent}{Pointer to a parent window.}
141
142 \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
143
144 \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
145 should generate a default position for the window. If using the wxWindow class directly, supply
146 an actual position.}
147
148 \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
149 should generate a default size for the window. If no suitable size can be found, the
150 window will be sized to 20x20 pixels so that the window is visible but obviously not
151 correctly sized. }
152
153 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
154
155 \docparam{name}{Window name.}
156
157
158 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
159
160 \func{}{\destruct{wxWindow}}{\void}
161
162 Destructor. Deletes all subwindows, then deletes itself. Instead of using
163 the {\bf delete} operator explicitly, you should normally
164 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
165 can delete a window only when it is safe to do so, in idle time.

173
174 \membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
175
176 \constfunc{bool}{AcceptsFocus}{\void}
177
178 This method may be overridden in the derived classes to return \false to
179 indicate that this control doesn't accept input at all (i.e. behaves like e.g.
180 \helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
181
182 \wxheading{See also}

184 \helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
185
186
187 \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
188
189 \constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
190
191 This method may be overridden in the derived classes to return \false to
192 indicate that while this control can, in principle, have focus if the user
193 clicks it with the mouse, it shouldn't be included in the TAB traversal chain
194 when using the keyboard.
195
196
197 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
198
199 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
200
201 Adds a child window. This is called automatically by window creation
202 functions so should not be required by the application programmer.
203
204 Notice that this function is mostly internal to wxWidgets and shouldn't be
205 called by the user code.
206
207 \wxheading{Parameters}
208
209 \docparam{child}{Child window to add.}
210
211
212 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
213
214 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
215
216 Sets the cached best size value.
217
218
219 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
220
221 \func{virtual void}{CaptureMouse}{\void}
222
223 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
224 release the capture.
225
226 Note that wxWidgets maintains the stack of windows having captured the mouse
227 and when the mouse is released the capture returns to the window which had had
228 captured it previously and it is only really released if there were no previous
229 window. In particular, this means that you must release the mouse as many times
230 as you capture it, unless the window receives
231 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
232
233 Any application which captures the mouse in the beginning of some operation
234 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
235 and cancel this operation when it receives the event. The event handler must
236 not recapture mouse.

261
262 A synonym for \helpref{CentreOnScreen}{wxwindowcentreonscreen}.
263
264
265 \membersection{wxWindow::Centre}\label{wxwindowcentre}
266
267 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
268
269 Centres the window.
270
271 \wxheading{Parameters}
272
273 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
274 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
275 if you want to center the window on the entire screen and not on its
276 parent window.}
277
278 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
279 (it has no effect).
280
281 \wxheading{Remarks}
282
283 If the window is a top level one (i.e. doesn't have a parent), it will be
284 centered relative to the screen anyhow.

291 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
292
293 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
294
295 Centres the window on its parent. This is a more readable synonym for
296 \helpref{Centre}{wxwindowcentre}.
297
298 \wxheading{Parameters}
299
300 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
301 or {\tt wxBOTH}.}
302
303 \wxheading{Remarks}
304
305 This methods provides for a way to center top level windows over their
306 parents instead of the entire screen. If there is no parent or if the
307 window is not a top level window, then behaviour is the same as
308 \helpref{wxWindow::Centre}{wxwindowcentre}.
309
310 \wxheading{See also}

315 \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
316
317 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
318
319 Centres the window on screen. This only works for top level windows -
320 otherwise, the window will still be centered on its parent.
321
322 \wxheading{Parameters}
323
324 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
325 or {\tt wxBOTH}.}

333
334 \func{void}{ClearBackground}{\void}
335
336 Clears the window by filling it with the current background colour. Does not
337 cause an erase background event to be generated.
338
339
340 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
341
342 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
343
344 \perlnote{In wxPerl this method returns a 2-element list instead of
345 modifying its parameters.}
346
347 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
348
349 Converts to screen coordinates from coordinates relative to this window.
350
351 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
352 a screen coordinate will be passed out.}
353
354 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
355 a screen coordinate will be passed out.}
356
357 \docparam{pt}{The client position for the second form of the function.}
358
359 \pythonnote{In place of a single overloaded method name, wxPython
360 implements the following methods:\par

366
367
368 \membersection{wxWindow::Close}\label{wxwindowclose}
369
370 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
371
372 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
373 handler usually tries to close the window. It doesn't close the window itself,
374 however.
375
376 \wxheading{Parameters}
377
378 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
379 of this window, {\tt true} if it cannot.}
380
381 \wxheading{Remarks}
382
383 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
384 an opportunity for the window to choose whether to destroy the window.
385 Usually it is only used with the top level windows (wxFrame and wxDialog
386 classes) as the others are not supposed to have any special OnClose() logic.
387
388 The close handler should check whether the window is being deleted forcibly,
389 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
390 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
391
392 {\it Note} that calling Close does not guarantee that the window will be
393 destroyed; but it provides a way to simulate a manual close of a window, which
394 may or may not be implemented by destroying the window. The default
395 implementation of wxDialog::OnCloseWindow does not necessarily delete the
396 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
397 the appropriate button event handler and may do anything at all.
398
399 To guarantee that the window will be destroyed, call
400 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

410
411 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
412
413 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
414
415 Converts a point or size from dialog units to pixels.
416
417 For the x dimension, the dialog units are multiplied by the average character width
418 and then divided by 4.
419
420 For the y dimension, the dialog units are multiplied by the average character height
421 and then divided by 8.
422
423 \wxheading{Remarks}
424
425 Dialog units are used for maintaining a dialog's proportions even if the font changes.
426
427 You can also use these functions programmatically. A convenience macro is defined:
428
429 {\small
430 \begin{verbatim}
431 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
432 \end{verbatim}

488
489 \func{virtual bool}{Destroy}{\void}
490
491 Destroys the window safely. Use this function instead of the delete operator, since
492 different window classes can be destroyed differently. Frames and dialogs
493 are not destroyed immediately when this function is called -- they are added
494 to a list of windows to be deleted on idle time, when all the window's events
495 have been processed. This prevents problems with events being sent to non-existent
496 windows.
497
498 \wxheading{Return value}

536 Does the window-specific updating after processing the update event.
537 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
538 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
539 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
540 implements this function as follows:
541
542 \begin{verbatim}
543 // do the window-specific processing after processing the update event
544 void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
545 {

681
682 \func{virtual void}{Fit}{\void}
683
684 Sizes the window so that it fits around its subwindows. This function won't do
685 anything if there are no subwindows and will only really work correctly if
686 sizers are used for the subwindows layout. Also, if the window has exactly one
687 subwindow it is better (faster and the result is more precise as Fit adds some
688 margin to account for fuzziness of its calculations) to call
689
690 \begin{verbatim}
691 window->SetClientSize(child->GetSize());

693
694 instead of calling Fit.

697 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}
698
699 \func{virtual void}{FitInside}{\void}
700
701 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
702 of a window. Mainly useful with scrolled windows to reset scrollbars after
703 sizing changes that do not trigger a size event, and/or scrolled windows without
704 an interior sizer. This function similarly won't do anything if there are no
705 subwindows.
706
707
708 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
709
710 \func{virtual void}{Freeze}{\void}
711
712 Freezes the window or, in other words, prevents any updates from taking place
713 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
714 be called to reenable window redrawing. Calls to these two functions may be
715 nested.
716
717 This method is useful for visual appearance optimization (for example, it
718 is a good idea to use it before doing many large text insertions in a row into
719 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
720 controls so it is mostly just a hint to wxWidgets and not a mandatory
721 directive.

769 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
770 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
771 application to implement (wxBG\_STYLE\_CUSTOM).
772
773 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
774 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

801 example, for a static control, it will be the minimal size such that the
802 control label is not truncated. For windows containing subwindows (typically
803 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the
804 same as the size the window would have had after calling

847
848 \constfunc{const wxWindowList\&}{GetChildren}{\void}
849
850 Returns a reference to the list of the window's children. \texttt{wxWindowList}
851 is a type-safe \helpref{wxList}{wxlist}-like class whose elements are of type
852 \texttt{wxWindow *}.

856
857 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
858
859 Returns the default font and colours which are used by the control. This is
860 useful if you want to use the same font or colour in your own control as in a
861 standard control -- which is a much better idea than hard coding specific
862 colours or fonts which might look completely out of place on the users
863 system, especially if it uses themes.
864
865 The \arg{variant} parameter is only relevant under Mac currently and is
866 ignore under other platforms. Under Mac, it will change the size of the
867 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
868 for more about this.
869
870 This static method is ``overridden'' in many derived classes and so calling,
871 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
872 return the values appropriate for a button which will be normally different
873 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
874
875 The \texttt{wxVisualAttributes} structure has at least the fields
876 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
877 if it was not possible to determine the default control appearance or,
878 especially for the background colour, if the field doesn't make sense as is
879 the case for \texttt{colBg} for the controls with themed background.

953 Currently this is the same as calling
954 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
955
956 One advantage of using this function compared to the static version is that
957 the call is automatically dispatched to the correct class (as usual with
958 virtual functions) and you don't have to specify the class name explicitly.
959
960 The other one is that in the future this function could return different
961 results, for example it might return a different font for an ``Ok'' button
962 than for a generic button if the users GUI is configured to show such buttons
963 in bold font. Of course, the down side is that it is impossible to call this
964 function without actually having an object to apply it to whereas the static
965 version can be used without having to create an object first.

1109 The interpretation of this function differs from class to class.
1110 For frames and dialogs, the value returned is the title. For buttons or static text controls, it is
1111 the button text. This function can be useful for meta-programs (such as testing
1112 tools or special-needs access programs) which need to identify windows
1113 by name.

1484
1485 This method is mostly used internally by the library itself and you normally
1486 shouldn't have to call it. You may, however, have to override it in your

1497 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1498
1499 \func{void}{InheritAttributes}{\void}
1500
1501 This function is (or should be, in case of custom controls) called during
1502 window creation to intelligently set up the window visual attributes, that is
1503 the font and the foreground and background colours.
1504
1505 By ``intelligently'' the following is meant: by default, all windows use their
1506 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1507 if some of the parents attributes are explicitly (that is, using
1508 \helpref{SetFont}{wxwindowsetfont} and not
1509 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1510 corresponding attribute hadn't been explicitly set for this window itself,
1511 then this window takes the same value as used by the parent. In addition, if
1512 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1513 to return \false, the colours will not be changed no matter what and only the
1514 font might.
1515
1516 This rather complicated logic is necessary in order to accommodate the
1517 different usage scenarios. The most common one is when all default attributes
1518 are used and in this case, nothing should be inherited as in modern GUIs
1519 different controls use different fonts (and colours) than their siblings so
1520 they can't inherit the same value from the parent. However it was also deemed
1521 desirable to allow to simply change the attributes of all children at once by
1522 just changing the font or colour of their common parent, hence in this case we
1523 do inherit the parents attributes.

1744
1745 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1746
1747 Moves this window in the tab navigation order after the specified \arg{win}.
1748 This means that when the user presses \texttt{TAB} key on that other window,
1749 the focus switches to this window.
1750
1751 Default tab order is the same as creation order, this function and
1752 \helpref{MoveBeforeInTabOrder()}{wxwindowmovebeforeintaborder} allow to change

1764
1765 Same as \helpref{MoveAfterInTabOrder}{wxwindowmoveafterintaborder} except that

1770 \membersection{wxWindow::Navigate}\label{wxwindownavigate}
1771
1772 \func{bool}{Navigate}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
1773
1774 Performs a keyboard navigation action starting from this window. This method is
1775 equivalent to calling \helpref{NavigateIn()}{wxwindownavigatein} method on the
1776 parent window.
1777
1778 \wxheading{Parameters}

1787 \wxheading{Remarks}
1788
1789 You may wish to call this from a text control custom keypress handler to do the default
1790 navigation behaviour for the tab key, since the standard default behaviour for
1791 a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
1792 and not navigate to the next control.

1807
1808 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1809 function allows to retrieve the effective id of the latter control from the id
1810 of the former. This is useful for example to find the control following its
1811 \helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the

2294 This virtual function is normally only used internally, but
2295 sometimes an application may need it to implement functionality
2296 that should not be disabled by an application defining an OnIdle
2297 handler in a derived class.

2337
2338 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2339
2340 Pops up the given menu at the specified coordinates, relative to this
2341 window, and returns control when the user has dismissed the menu. If a
2342 menu item is selected, the corresponding menu event is generated and will be
2343 processed as usually. If the coordinates are not specified, current mouse
2344 cursor position is used.

2365
2366 It is recommended to not explicitly specify coordinates when calling PopupMenu

2394
2395 \docparam{handler}{Specifies the handler to be pushed.}
2396
2397 \wxheading{Remarks}
2398
2399 An event handler is an object that is capable of processing the events
2400 sent to a window. By default, the window is its own event handler, but
2401 an application may wish to substitute another, for example to allow
2402 central implementation of event-handling for a variety of different
2403 window classes.
2404
2405 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2406 an application to set up a chain of event handlers, where an event not handled by one event handler is
2407 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2408 remove the event handler.

2435
2436 Causes this window, and all of its children recursively (except under wxGTK1
2437 where this is not implemented), to be repainted. Note that repainting doesn't
2438 happen immediately but only during the next event loop iteration, if you need

2458
2459 Redraws the contents of the given rectangle: only the area inside it will be
2460 repainted.
2461
2462 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2468
2469 \func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
2470
2471 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2472 will receive a hotkey event. It will receive the event even if the application is in the background
2473 and does not have the input focus because the user is working with some other application.
2474
2475 \wxheading{Parameters}
2476
2477 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If
2478 this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF.

2688 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2689 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2690 manually or otherwise the window layout won't be correctly updated when its
2691 size changes.
2692
2693 \wxheading{Parameters}
2694
2695 \docparam{autoLayout}{Set this to \true if you wish the Layout function to be
2696 called automatically when the window is resized.}

2703 \membersection{wxWindow::SetBackgroundColour}\label{wxwindowsetbackgroundcolour}
2704
2705 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2706
2707 Sets the background colour of the window.
2708
2709 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2710 explanation of the difference between this method and
2711 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2712
2713 \wxheading{Parameters}
2714
2715 \docparam{colour}{The colour to be used as the background colour, pass
2716 {\tt wxNullColour} to reset to the default colour.}
2717
2718 \wxheading{Remarks}
2719
2720 The background colour is usually painted by the default\rtfsp
2721 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2722 under Windows and automatically under GTK.
2723
2724 Note that setting the background colour does not cause an immediate refresh, so you
2725 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2726 calling this function.
2727
2728 Using this function will disable attempts to use themes for this
2729 window, if the system supports them. Use with care since usually the
2730 themes represent the appearance chosen by the user to be used for all
2731 applications on the system.

2743 \membersection{wxWindow::SetBackgroundStyle}\label{wxwindowsetbackgroundstyle}
2744
2745 \func{virtual void}{SetBackgroundStyle}{\param{wxBackgroundStyle}{ style}}
2746
2747 Sets the background style of the window. The background style indicates
2748 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2749 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2750 application to implement (wxBG\_STYLE\_CUSTOM).
2751
2752 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2753 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2763
2764 \func{void}{SetInitialSize}{\param{const wxSize\& }{size = wxDefaultSize}}
2765
2766 A {\it smart} SetSize that will fill in default size components with the
2767 window's {\it best} size values. Also sets the window's minsize to
2768 the value passed in for use with sizers. This means that if a full or
2769 partial size is passed to this function then the sizers will use that
2770 size instead of the results of GetBestSize to determine the minimum
2771 needs of the window for layout.
2772
2773 Most controls will use this to set their initial size, and their min
2774 size to the passed in value (if any.)

2793 \func{virtual void}{SetClientSize}{\param{int}{ width}, \param{int}{ height}}
2794
2795 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2796
2797 This sets the size of the window client area in pixels. Using this function to size a window
2798 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2799 worry about what dimensions the border or title bar have when trying to fit the window
2800 around panel items, for example.
2801
2802 \wxheading{Parameters}
2803
2804 \docparam{width}{The required client area width.}
2805
2806 \docparam{height}{The required client area height.}

2819 \membersection{wxWindow::SetConstraints}\label{wxwindowsetconstraints}
2820
2821 \func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2822
2823 Sets the window to have the given layout constraints. The window
2824 will then own the object, and will take care of its deletion.
2825 If an existing layout constraints object is already owned by the
2826 window, it will be deleted.
2827
2828 \wxheading{Parameters}
2829
2830 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2831 constraints.}
2832
2833 \wxheading{Remarks}
2834
2835 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2836 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2837 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2838 sizer will have effect.
2839
2840 \membersection{wxWindow::SetContainingSizer}\label{wxwindowsetcontainingsizer}
2841
2842 \func{void}{SetContainingSizer}{\param{wxSizer* }{sizer}}
2843
2844 This normally does not need to be called by user code. It is called
2845 when a window is added to a sizer, and is used so the window can
2846 remove itself from the sizer when it is destroyed.

2849 \membersection{wxWindow::SetCursor}\label{wxwindowsetcursor}

2854 % changed
2855 Sets the window's cursor. Notice that the window cursor also sets it for the
2856 children of the window implicitly.
2857
2858 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2859 be reset back to default.
2860

2890 components of the size passed to ctor/Create() is wxDefaultCoord).
2891
2892 \membersection{wxWindow::SetEventHandler}\label{wxwindowseteventhandler}
2893
2894 \func{void}{SetEventHandler}{\param{wxEvtHandler* }{handler}}
2895
2896 Sets the event handler for this window.
2897
2898 \wxheading{Parameters}
2899
2900 \docparam{handler}{Specifies the handler to be set.}
2901
2902 \wxheading{Remarks}
2903
2904 An event handler is an object that is capable of processing the events
2905 sent to a window. By default, the window is its own event handler, but
2906 an application may wish to substitute another, for example to allow
2907 central implementation of event-handling for a variety of different
2908 window classes.
2909
2910 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2911 this sets up a chain of event handlers, where an event not handled by one event handler is
2912 handed to the next one in the chain.

2924
2925 \func{void}{SetExtraStyle}{\param{long }{exStyle}}
2926
2927 Sets the extra style bits for the window. The currently defined extra style
2928 bits are:
2929
2930 \twocolwidtha{5cm}%
2931 \begin{twocollist}\itemsep=0pt
2932 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2933 and Validate() methods will recursively descend into all children of the
2934 window if it has this style flag set.}
2935 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2936 events are propagated upwards to the window parent recursively until a handler
2937 for them is found. Using this style allows to prevent them from being
2938 propagated beyond this window. Notice that wxDialog has this style on by
2939 default for the reasons explained in the
2940 \helpref{event processing overview}{eventprocessing}.}
2941 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2942 window from being used as an implicit parent for the dialogs which were
2943 created without a parent. It is useful for the windows which can disappear at
2944 any moment as creating children of such windows results in fatal problems.}
2945 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2946 button on the caption. When pressed, Windows will go into a context-sensitive
2947 help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an
2948 application window.
2949 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2950 these two styles are automatically turned of if this one is used.}
2951 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
2952 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
2953 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
2954 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

2972
2973 \func{virtual void}{SetFocusFromKbd}{\void}
2974
2975 This function is called by wxWidgets keyboard navigation code when the user
2976 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2977 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but
2978 can be overridden to do something in addition to this in the derived classes.

2981 \membersection{wxWindow::SetFont}\label{wxwindowsetfont}
2982
2983 \func{bool}{SetFont}{\param{const wxFont\& }{font}}

2985 Sets the font for this window. This function should not be called for the
2986 parent window if you don't want its font to be inherited by its children,
2987 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
2988 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
2989 explanations.
2990
2991 Please notice that the given font is \emph{not} automatically used for
2992 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
2993 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by
2994 any standard controls for drawing their text as well as by
2995 \helpref{wxWindow::GetTextExtent()}{wxwindowgettextextent}.

3017 Sets the foreground colour of the window.
3018
3019 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
3020 explanation of the difference between this method and

3029
3030 The interpretation of foreground colour is open to interpretation according
3031 to the window class; it may be the text colour or other colour, or it may not
3032 be used at all.
3033
3034 Using this function will disable attempts to use themes for this
3035 window, if the system supports them. Use with care since usually the

3193
3194 Let's say you wish to display 50 lines of text, using the same font.
3195 The window is sized so that you can only see 16 lines at a time.
3196
3197 You would use:
3198
3199 {\small%
3200 \begin{verbatim}
3201 SetScrollbar(wxVERTICAL, 0, 16, 50);
3202 \end{verbatim}
3203 }
3204
3205 Note that with the window at this size, the thumb position can never go
3206 above 50 minus 16, or 34.

3208 You can determine how many lines are currently visible by dividing the current view
3209 size by the character height in pixels.
3210
3211 When defining your own scrollbar behaviour, you will always need to recalculate
3212 the scrollbar settings when the window size changes. You could therefore put your
3213 scrollbar calculations and SetScrollbar
3214 call into a function named AdjustScrollbars, which can be called initially and also
3215 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3241
3242 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3243 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3244 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3245 value has to be adjusted when the window is resized, since the page size will have changed.
3246
3247 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3248 the thumb changes size to reflect the page size relative to the length of the document. When the
3249 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3250 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3251 disappear.
3252
3253 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3254 handling of pages and ranges.

3309
3310 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3311 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3312 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3313 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3314 and usually the scrollbar will be automatically hidden.

3418 If an existing layout constraints object is already owned by the
3419 window, it will be deleted if the deleteOld parameter is true.
3420
3421 Note that this function will also call

3456 This function tells a window if it should use the system's "theme" code
3457 to draw the windows' background instead if its own background drawing
3458 code. This does not always have any effect since the underlying platform
3459 obviously needs to support the notion of themes in user defined windows.
3460 One such platform is GTK+ where windows can have (very colourful) backgrounds
3461 defined by a user's selected theme.

3721 example a wxToolBar will send an update UI event for each toolbar button,
3722 and a wxFrame will send an update UI event for each menubar menu item.
3723 You can call this function from your application to ensure that your
3724 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3725 are concerned). This may be necessary if you have called
3726 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3727 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3728 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3729
3730 {\it flags} should be a bitlist of one or more of the following values.
3731
3732 \begin{verbatim}
3733 enum wxUpdateUI
3734 {
3735 wxUPDATE_UI_NONE = 0x0000, // No particular value
3736 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3737 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3738 };
3739 \end{verbatim}
3740
3741 If you are calling this function from an OnInternalIdle or OnIdle
3742 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3743 this tells the window to only update the UI elements that need
3744 to be updated in idle time. Some windows update their elements
3745 only when necessary, for example when a menu is about to be shown.
3746 The following is an example of how to call UpdateWindowUI from
3747 an idle function.
3748
3749 \begin{verbatim}
3750 void MyWindow::OnInternalIdle()
3751 {
3752 if (wxUpdateUIEvent::CanUpdate(this))
3753 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3754 }
3755 \end{verbatim}

3764 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
3765
3766 \func{virtual bool}{Validate}{\void}
3767
3768 Validates the current values of the child controls using their validators.
3769
3770 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3771 the method will also call Validate() of all child windows.
3772
3773 \wxheading{Return value}
3774
3775 Returns {\tt false} if any of the validations failed.
