12 \section{\class{wxWindow}}\label{wxwindow}
13
14 wxWindow is the base class for all windows and represents any visible object on
15 screen. All controls, top level windows and so on are windows. Sizers and
16 device contexts are not, however, as they don't appear on screen themselves.
17
18 Please note that all children of the window will be deleted automatically by
19 the destructor before the window itself is deleted which means that you don't
20 have to worry about deleting them manually. Please see the \helpref{window
21 deletion overview}{windowdeletionoverview} for more information.
22
23 Also note that in this, and many others, wxWidgets classes some
24 \texttt{GetXXX()} methods may be overloaded (as, for example,
25 \helpref{GetSize}{wxwindowgetsize} or
26 \helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
27 are non-virtual because having multiple virtual functions with the same name
28 results in a virtual function name hiding at the derived class level (in
29 English, this means that the derived class has to override all overloaded
30 variants if it overrides any of them). To allow overriding them in the derived
31 class, wxWidgets uses a unique protected virtual \texttt{DoGetXXX()} method
32 and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
33 changes the behaviour of the latter.

50 The following styles can apply to all windows, although they will not always make sense for a particular
51 window class or on all platforms.
52
53 \twocolwidtha{5cm}%
54 \begin{twocollist}\itemsep=0pt
55 \twocolitem{\windowstyle{wxBORDER\_DEFAULT}}{The window class will decide the kind of border to show, if any.}
56 \twocolitem{\windowstyle{wxBORDER\_SIMPLE}}{Displays a thin border around the window. wxSIMPLE\_BORDER is the old name
57 for this style. }
58 \twocolitem{\windowstyle{wxBORDER\_SUNKEN}}{Displays a sunken border. wxSUNKEN\_BORDER is the old name for this style.}
59 \twocolitem{\windowstyle{wxBORDER\_RAISED}}{Displays a raised border. wxRAISED\_BORDER is the old name for this style. }
60 \twocolitem{\windowstyle{wxBORDER\_STATIC}}{Displays a border suitable for a static control. wxSTATIC\_BORDER is the old name for this style. Windows only. }
61 \twocolitem{\windowstyle{wxBORDER\_THEME}}{Displays a native border suitable for a control, on the current platform. On Windows XP or Vista, this will be a themed border; on most other platforms
62 a sunken border will be used. For more information for themed borders on Windows, please see \helpref{Themed borders on Windows}{wxmswthemedborders}.}
63 \twocolitem{\windowstyle{wxBORDER\_NONE}}{Displays no border, overriding the default border style for the window. wxNO\_BORDER is the old name for this style.}
64 \twocolitem{\windowstyle{wxBORDER\_DOUBLE}}{This style is obsolete and should not be used.}
65 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
66 events. Windows only.}
67 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
68 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
69 the window wants to get all char/key events for all keys - even for
70 keys like TAB or ENTER which are usually used for dialog navigation
71 and which wouldn't be generated without this style. If you need to
72 use this style in order to get the arrows or etc., but would still like
73 to have normal keyboard navigation take place, you should call
74 \helpref{Navigate}{wxwindownavigate} in response to the key events for
75 Tab and Shift-Tab.}
76 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
77 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
78 and no longer has an effect.}
79 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical
80 scrollbar. Notice that this style cannot be used with native controls
81 which don't support scrollbars nor with top-level windows in most ports.}
82 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal
83 scrollbar. The same limitations as for wxVSCROLL apply to this style.}
84 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
85 disable them instead of hiding them when they are not needed (i.e. when the
86 size of the window is big enough to not require the scrollbars to navigate it).
87 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
88 nothing on the other platforms.}
89 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
90 repainted, then children being painted over them. Windows only.}
91 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
92 a complete redraw of the window whenever it is resized instead of redrawing
93 just the part of the window affected by resizing. Note that this was the
94 behaviour by default before 2.5.1 release and that if you experience redraw
95 problems with code which previously used to work you may want to try this.
96 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
97 done on other platforms.}

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

134 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
135
136 \func{}{wxWindow}{\void}
137
138 Default constructor.
139
140 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
141 \param{const wxPoint\& }{pos = wxDefaultPosition},
142 \param{const wxSize\& }{size = wxDefaultSize},
143 \param{long }{style = 0},
144 \param{const wxString\& }{name = wxPanelNameStr}}
145
146 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
147
148 \wxheading{Parameters}
149
150 \docparam{parent}{Pointer to a parent window.}
151
152 \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
153
154 \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
155 should generate a default position for the window. If using the wxWindow class directly, supply
156 an actual position.}
157
158 \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
159 should generate a default size for the window. If no suitable size can be found, the
160 window will be sized to 20x20 pixels so that the window is visible but obviously not
161 correctly sized. }
162
163 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
164
165 \docparam{name}{Window name.}
166
167
168 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
169
170 \func{}{\destruct{wxWindow}}{\void}
171
172 Destructor. Deletes all subwindows, then deletes itself. Instead of using
173 the {\bf delete} operator explicitly, you should normally
174 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
175 can delete a window only when it is safe to do so, in idle time.

183
184 \membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
185
186 \constfunc{bool}{AcceptsFocus}{\void}
187
188 This method may be overridden in the derived classes to return \false to
189 indicate that this control doesn't accept input at all (i.e. behaves like e.g.
190 \helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
191
192 \wxheading{See also}

194 \helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
195
196
197 \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
198
199 \constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
200
201 This method may be overridden in the derived classes to return \false to
202 indicate that while this control can, in principle, have focus if the user
203 clicks it with the mouse, it shouldn't be included in the TAB traversal chain
204 when using the keyboard.
205
206
207 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
208
209 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
210
211 Adds a child window. This is called automatically by window creation
212 functions so should not be required by the application programmer.
213
214 Notice that this function is mostly internal to wxWidgets and shouldn't be
215 called by the user code.
216
217 \wxheading{Parameters}
218
219 \docparam{child}{Child window to add.}
220
221
222 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
223
224 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
225
226 Sets the cached best size value.
227
228
229 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
230
231 \func{virtual void}{CaptureMouse}{\void}
232
233 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
234 release the capture.
235
236 Note that wxWidgets maintains the stack of windows having captured the mouse
237 and when the mouse is released the capture returns to the window which had had
238 captured it previously and it is only really released if there were no previous
239 window. In particular, this means that you must release the mouse as many times
240 as you capture it, unless the window receives
241 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
242
243 Any application which captures the mouse in the beginning of some operation
244 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
245 and cancel this operation when it receives the event. The event handler must
246 not recapture mouse.

273
274
275 \membersection{wxWindow::Centre}\label{wxwindowcentre}
276
277 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
278
279 Centres the window.
280
281 \wxheading{Parameters}
282
283 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
284 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
285 if you want to center the window on the entire screen and not on its
286 parent window.}
287
288 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
289 (it has no effect).
290
291 \wxheading{Remarks}
292
293 If the window is a top level one (i.e. doesn't have a parent), it will be
294 centered relative to the screen anyhow.

302
303 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
304
305 Centres the window on its parent. This is a more readable synonym for
306 \helpref{Centre}{wxwindowcentre}.
307
308 \wxheading{Parameters}
309
310 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
311 or {\tt wxBOTH}.}
312
313 \wxheading{Remarks}
314
315 This methods provides for a way to center top level windows over their
316 parents instead of the entire screen. If there is no parent or if the
317 window is not a top level window, then behaviour is the same as
318 \helpref{wxWindow::Centre}{wxwindowcentre}.

326
327 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
328
329 Centres the window on screen. This only works for top level windows -
330 otherwise, the window will still be centered on its parent.
331
332 \wxheading{Parameters}
333
334 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

355 modifying its parameters.}
356
357 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
358
359 Converts to screen coordinates from coordinates relative to this window.
360
361 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
362 a screen coordinate will be passed out.}

377
378 \membersection{wxWindow::Close}\label{wxwindowclose}
379
380 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
381
382 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
383 handler usually tries to close the window. It doesn't close the window itself,
384 however.
385
386 \wxheading{Parameters}
387
388 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
389 of this window, {\tt true} if it cannot.}
390
391 \wxheading{Remarks}
392
393 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
394 an opportunity for the window to choose whether to destroy the window.
395 Usually it is only used with the top level windows (wxFrame and wxDialog
396 classes) as the others are not supposed to have any special OnClose() logic.
397
398 The close handler should check whether the window is being deleted forcibly,
399 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
400 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
401
402 {\it Note} that calling Close does not guarantee that the window will be
403 destroyed; but it provides a way to simulate a manual close of a window, which
404 may or may not be implemented by destroying the window. The default
405 implementation of wxDialog::OnCloseWindow does not necessarily delete the
406 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
407 the appropriate button event handler and may do anything at all.
408
409 To guarantee that the window will be destroyed, call
410 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

420
421 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
422
423 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
424
425 Converts a point or size from dialog units to pixels.
426
427 For the x dimension, the dialog units are multiplied by the average character width
428 and then divided by 4.
429
430 For the y dimension, the dialog units are multiplied by the average character height
431 and then divided by 8.
432
433 \wxheading{Remarks}
434
435 Dialog units are used for maintaining a dialog's proportions even if the font changes.
436
437 You can also use these functions programmatically. A convenience macro is defined:
438
439 {\small
440 \begin{verbatim}
441 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

498
499 \func{virtual bool}{Destroy}{\void}
500
501 Destroys the window safely. Use this function instead of the delete operator, since
502 different window classes can be destroyed differently. Frames and dialogs
503 are not destroyed immediately when this function is called -- they are added
504 to a list of windows to be deleted on idle time, when all the window's events
505 have been processed. This prevents problems with events being sent to non-existent
506 windows.
507
508 \wxheading{Return value}

546 Does the window-specific updating after processing the update event.
547 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
548 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
549 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
550 implements this function as follows:

693
694 Sizes the window so that it fits around its subwindows. This function won't do
695 anything if there are no subwindows and will only really work correctly if
696 sizers are used for the subwindows layout. Also, if the window has exactly one
697 subwindow it is better (faster and the result is more precise as Fit adds some
698 margin to account for fuzziness of its calculations) to call
699
700 \begin{verbatim}

712 of a window. Mainly useful with scrolled windows to reset scrollbars after
713 sizing changes that do not trigger a size event, and/or scrolled windows without
714 an interior sizer. This function similarly won't do anything if there are no
715 subwindows.
716
717
718 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

720 \func{virtual void}{Freeze}{\void}
721
722 Freezes the window or, in other words, prevents any updates from taking place
723 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
724 be called to reenable window redrawing. Calls to these two functions may be
725 nested.
726
727 This method is useful for visual appearance optimization (for example, it
728 is a good idea to use it before doing many large text insertions in a row into
729 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
730 controls so it is mostly just a hint to wxWidgets and not a mandatory

867 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
868
869 Returns the default font and colours which are used by the control. This is
870 useful if you want to use the same font or colour in your own control as in a
871 standard control -- which is a much better idea than hard coding specific
872 colours or fonts which might look completely out of place on the users
873 system, especially if it uses themes.
874
875 The \arg{variant} parameter is only relevant under Mac currently and is
876 ignore under other platforms. Under Mac, it will change the size of the
877 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
878 for more about this.
879
880 This static method is ``overridden'' in many derived classes and so calling,
881 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
882 return the values appropriate for a button which will be normally different
883 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
884
885 The \texttt{wxVisualAttributes} structure has at least the fields
886 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
887 if it was not possible to determine the default control appearance or,
888 especially for the background colour, if the field doesn't make sense as is
889 the case for \texttt{colBg} for the controls with themed background.

963 Currently this is the same as calling
964 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
965
966 One advantage of using this function compared to the static version is that
967 the call is automatically dispatched to the correct class (as usual with
968 virtual functions) and you don't have to specify the class name explicitly.
969
970 The other one is that in the future this function could return different
971 results, for example it might return a different font for an ``Ok'' button
972 than for a generic button if the users GUI is configured to show such buttons
973 in bold font. Of course, the down side is that it is impossible to call this
974 function without actually having an object to apply it to whereas the static
975 version can be used without having to create an object first.

1520
1521 \func{void}{InheritAttributes}{\void}
1522
1523 This function is (or should be, in case of custom controls) called during
1524 window creation to intelligently set up the window visual attributes, that is
1525 the font and the foreground and background colours.
1526
1527 By ``intelligently'' the following is meant: by default, all windows use their
1528 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1529 if some of the parents attributes are explicitly (that is, using
1530 \helpref{SetFont}{wxwindowsetfont} and not
1531 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1532 corresponding attribute hadn't been explicitly set for this window itself,
1533 then this window takes the same value as used by the parent. In addition, if
1534 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1535 to return \false, the colours will not be changed no matter what and only the
1536 font might.
1537
1538 This rather complicated logic is necessary in order to accommodate the
1539 different usage scenarios. The most common one is when all default attributes
1540 are used and in this case, nothing should be inherited as in modern GUIs
1541 different controls use different fonts (and colours) than their siblings so
1542 they can't inherit the same value from the parent. However it was also deemed
1543 desirable to allow to simply change the attributes of all children at once by
1544 just changing the font or colour of their common parent, hence in this case we
1545 do inherit the parents attributes.

1766
1767 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1768
1769 Moves this window in the tab navigation order after the specified \arg{win}.
1770 This means that when the user presses \texttt{TAB} key on that other window,
1771 the focus switches to this window.
1772
1773 Default tab order is the same as creation order, this function and
1774 \helpref{MoveBeforeInTabOrder()}{wxwindowmovebeforeintaborder} allow to change

1792 \membersection{wxWindow::Navigate}\label{wxwindownavigate}
1793
1794 \func{bool}{Navigate}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
1795
1796 Performs a keyboard navigation action starting from this window. This method is
1797 equivalent to calling \helpref{NavigateIn()}{wxwindownavigatein} method on the
1798 parent window.
1799
1800 \wxheading{Parameters}
1801
1802 \docparam{flags}{A combination of wxNavigationKeyEvent::IsForward and wxNavigationKeyEvent::WinChange.}

1809 \wxheading{Remarks}
1810
1811 You may wish to call this from a text control custom keypress handler to do the default
1812 navigation behaviour for the tab key, since the standard default behaviour for
1813 a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
1814 and not navigate to the next control. See also \helpref{wxNavigationKeyEvent}{wxnavigationkeyevent}.

1829
1830 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1831 function allows to retrieve the effective id of the latter control from the id
1832 of the former. This is useful for example to find the control following its
1833 \helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the

2156 %% Use the EVT\_PAINT macro in an event table definition to intercept paint events.
2157 %%
2158 %% Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
2159 %% even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong.
2160 %%
2161 %% For example:
2162 %%
2163 %% \small{%
2164 %% \begin{verbatim}
2165 %% void MyWindow::OnPaint(wxPaintEvent\& event)
2166 %% {

2169 %% DrawMyDocument(dc);
2170 %% }
2171 %% \end{verbatim}
2172 %% }%
2173 %%
2174 %% You can optimize painting by retrieving the rectangles
2175 %% that have been damaged and only repainting these. The rectangles are in
2176 %% terms of the client area, and are unscrolled, so you will need to do
2177 %% some calculations using the current view position to obtain logical,
2178 %% scrolled units.
2179 %%

2183 %% \begin{verbatim}
2184 %% // Called when window needs to be repainted.
2185 %% void MyWindow::OnPaint(wxPaintEvent\& event)
2186 %% {
2187 %% wxPaintDC dc(this);
2188 %%
2189 %% // Find Out where the window is scrolled to
2190 %% int vbX,vbY; // Top left corner of client
2191 %% GetViewStart(&vbX,&vbY);

2360 \func{bool}{PopupMenu}{\param{wxMenu* }{menu}, \param{int }{x}, \param{int }{y}}
2361
2362 Pops up the given menu at the specified coordinates, relative to this
2363 window, and returns control when the user has dismissed the menu. If a
2364 menu item is selected, the corresponding menu event is generated and will be
2365 processed as usually. If the coordinates are not specified, current mouse

2418
2419 \wxheading{Remarks}
2420
2421 An event handler is an object that is capable of processing the events
2422 sent to a window. By default, the window is its own event handler, but
2423 an application may wish to substitute another, for example to allow
2424 central implementation of event-handling for a variety of different
2425 window classes.
2426
2427 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2428 an application to set up a chain of event handlers, where an event not handled by one event handler is
2429 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2430 remove the event handler.

2458 Causes this window, and all of its children recursively (except under wxGTK1
2459 where this is not implemented), to be repainted. Note that repainting doesn't
2460 happen immediately but only during the next event loop iteration, if you need

2483
2484 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2492
2493 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2494 will receive a hotkey event. It will receive the event even if the application is in the background
2495 and does not have the input focus because the user is working with some other application.
2496
2497 \wxheading{Parameters}
2498
2499 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2699 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2700
2701 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2702
2703 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2704 be called automatically when the window is resized. Please note that this only
2705 happens for the windows usually used to contain children, namely
2706 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2707 (and the classes deriving from them).
2708
2709 This method is called implicitly by
2710 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2711 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2712 manually or otherwise the window layout won't be correctly updated when its
2713 size changes.
2714
2715 \wxheading{Parameters}
2716
2717 \docparam{autoLayout}{Set this to \true if you wish the Layout function to be
2718 called automatically when the window is resized.}

2726
2727 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2728
2729 Sets the background colour of the window.
2730
2731 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2732 explanation of the difference between this method and
2733 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2734
2735 \wxheading{Parameters}
2736
2737 \docparam{colour}{The colour to be used as the background colour, pass
2738 {\tt wxNullColour} to reset to the default colour.}
2739
2740 \wxheading{Remarks}
2741
2742 The background colour is usually painted by the default\rtfsp
2743 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2744 under Windows and automatically under GTK.
2745
2746 Note that setting the background colour does not cause an immediate refresh, so you
2747 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2748 calling this function.
2749
2750 Using this function will disable attempts to use themes for this
2751 window, if the system supports them. Use with care since usually the
2752 themes represent the appearance chosen by the user to be used for all
2753 applications on the system.

2766
2767 \func{virtual void}{SetBackgroundStyle}{\param{wxBackgroundStyle}{ style}}
2768
2769 Sets the background style of the window. The background style indicates
2770 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2771 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2772 application to implement (wxBG\_STYLE\_CUSTOM).
2773
2774 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2775 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2788
2789 This method is only implemented by ports which have support for
2790 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2791 container control code to give the native system a hint when
2792 doing TAB traversal. A call to this does not disable or change
2793 the effect of programmatically calling
2794 \helpref{wxWindow::SetFocus}{wxwindowsetfocus}.

2813
2814 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2815
2816 This sets the size of the window client area in pixels. Using this function to size a window
2817 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2818 worry about what dimensions the border or title bar have when trying to fit the window
2819 around panel items, for example.
2820
2821 \wxheading{Parameters}
2822
2823 \docparam{width}{The required client area width.}
2824

2842 Sets the window to have the given layout constraints. The window
2843 will then own the object, and will take care of its deletion.
2844 If an existing layout constraints object is already owned by the
2845 window, it will be deleted.
2846
2847 \wxheading{Parameters}
2848
2849 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2850 constraints.}
2851
2852 \wxheading{Remarks}
2853
2854 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2855 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2856 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2857 sizer will have effect.

2863 This normally does not need to be called by user code. It is called

2910 \wxheading{Parameters}
2911
2912 \docparam{handler}{Specifies the handler to be set.}
2913
2914 \wxheading{Remarks}
2915
2916 An event handler is an object that is capable of processing the events
2917 sent to a window. By default, the window is its own event handler, but
2918 an application may wish to substitute another, for example to allow
2919 central implementation of event-handling for a variety of different
2920 window classes.
2921
2922 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
2923 since this sets up a chain of event handlers, where an event not handled by
2924 one event handler is handed to the next one in the chain.

2943 \begin{twocollist}\itemsep=0pt
2944 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
2945 and Validate() methods will recursively descend into all children of the
2946 window if it has this style flag set.}
2947 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2948 events are propagated upwards to the window parent recursively until a handler
2949 for them is found. Using this style allows to prevent them from being
2950 propagated beyond this window. Notice that wxDialog has this style on by
2951 default for the reasons explained in the
2952 \helpref{event processing overview}{eventprocessing}.}
2953 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2954 window from being used as an implicit parent for the dialogs which were
2955 created without a parent. It is useful for the windows which can disappear at
2956 any moment as creating children of such windows results in fatal problems.}
2957 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2958 button on the caption. When pressed, Windows will go into a context-sensitive
2959 help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an
2960 application window.
2961 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2962 these two styles are automatically turned of if this one is used.}
2963 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even

2986
2987 This function is called by wxWidgets keyboard navigation code when the user
2988 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2989 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but
2990 can be overridden to do something in addition to this in the derived classes.

2999 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3000 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3001 explanations.
3002
3003 Please notice that the given font is \emph{not} automatically used for
3004 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
3005 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3045
3046 Using this function will disable attempts to use themes for this

3236 Let's say you wish to display 50 lines of text, using the same font.
3237 The window is sized so that you can only see 16 lines at a time.
3238
3239 You would use:
3240
3241 {\small%
3242 \begin{verbatim}
3243 SetScrollbar(wxVERTICAL, 0, 16, 50);
3244 \end{verbatim}
3245 }
3246
3247 Note that with the window at this size, the thumb position can never go
3248 above 50 minus 16, or 34.
3249
3250 You can determine how many lines are currently visible by dividing the current view
3251 size by the character height in pixels.
3252
3253 When defining your own scrollbar behaviour, you will always need to recalculate
3254 the scrollbar settings when the window size changes. You could therefore put your
3255 scrollbar calculations and SetScrollbar
3256 call into a function named AdjustScrollbars, which can be called initially and also
3257 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3283
3284 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3285 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3286 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3287 value has to be adjusted when the window is resized, since the page size will have changed.
3288
3289 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3290 the thumb changes size to reflect the page size relative to the length of the document. When the
3291 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3292 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3293 disappear.
3294
3295 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3296 handling of pages and ranges.

3351
3352 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3353 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3354 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3355 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3356 and usually the scrollbar will be automatically hidden.

3498 This function tells a window if it should use the system's "theme" code
3499 to draw the windows' background instead if its own background drawing
3500 code. This does not always have any effect since the underlying platform
3501 obviously needs to support the notion of themes in user defined windows.
3502 One such platform is GTK+ where windows can have (very colourful) backgrounds
3503 defined by a user's selected theme.

3746 \func{virtual void}{Update}{\void}
3747
3748 Calling this method immediately repaints the invalidated area of the window and
3749 all of its children recursively while this would usually only happen when the
3750 flow of control returns to the event loop.
3751 Notice that this function doesn't invalidate any area of the window so
3752 nothing happens if nothing has been invalidated (i.e. marked as requiring
3753 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3754 immediately redraw the window unconditionally.

3758
3759 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3760
3761 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3762 the window. The particular implementation depends on the window; for
3763 example a wxToolBar will send an update UI event for each toolbar button,
3764 and a wxFrame will send an update UI event for each menubar menu item.
3765 You can call this function from your application to ensure that your
3766 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3767 are concerned). This may be necessary if you have called
3768 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3769 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3770 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3771
3772 {\it flags} should be a bitlist of one or more of the following values.
3773
3774 \begin{verbatim}
3775 enum wxUpdateUI
3776 {
3777 wxUPDATE_UI_NONE = 0x0000, // No particular value
3778 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3779 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3780 };
3781 \end{verbatim}
3782
3783 If you are calling this function from an OnInternalIdle or OnIdle
3784 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3785 this tells the window to only update the UI elements that need
3786 to be updated in idle time. Some windows update their elements
3787 only when necessary, for example when a menu is about to be shown.
3788 The following is an example of how to call UpdateWindowUI from
3789 an idle function.
3790
3791 \begin{verbatim}
3792 void MyWindow::OnInternalIdle()
3793 {
3794 if (wxUpdateUIEvent::CanUpdate(this))
3795 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3796 }

3806 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
3807
3808 \func{virtual bool}{Validate}{\void}
3809
3810 Validates the current values of the child controls using their validators.
3811
3812 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3813 the method will also call Validate() of all child windows.
3814
3815 \wxheading{Return value}
3816
3817 Returns {\tt false} if any of the validations failed.
