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.

49
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\_SIMPLE}}{Displays a thin border around the window. wxBORDER is the old name
56 for this style. }
57 \twocolitem{\windowstyle{wxBORDER\_DOUBLE}}{Displays a double border. Windows and Mac only.}
58 \twocolitem{\windowstyle{wxBORDER\_SUNKEN}}{Displays a sunken border.}
59 \twocolitem{\windowstyle{wxBORDER\_RAISED}}{Displays a raised border.}
60 \twocolitem{\windowstyle{wxBORDER\_STATIC}}{Displays a border suitable for a static control. Windows only. }
61 \twocolitem{\windowstyle{wxBORDER\_NONE}}{Displays no border, overriding the default border style for the window.}
62 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
63 events. Windows only.}
64 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
65 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
66 the window wants to get all char/key events for all keys - even for
67 keys like TAB or ENTER which are usually used for dialog navigation
68 and which wouldn't be generated without this style. If you need to
69 use this style in order to get the arrows or etc., but would still like
70 to have normal keyboard navigation take place, you should call
71 \helpref{Navigate}{wxwindownavigate} in response to the key events for
72 Tab and Shift-Tab.}
73 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{On Windows, this style used to disable repainting
74 the window completely when its size is changed. Since this behaviour is now the default, the style is now obsolete
75 and no longer has an effect.}
76 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical
77 scrollbar. Notice that this style cannot be used with native controls
78 which don't support scrollbars nor with top-level windows in most ports.}
79 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal
80 scrollbar. The same limitations as for wxVSCROLL apply to this style.}
81 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
82 disable them instead of hiding them when they are not needed (i.e. when the
83 size of the window is big enough to not require the scrollbars to navigate it).
84 This style is currently implemented for wxMSW, wxGTK and wxUniversal and does
85 nothing on the other platforms.}
86 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
87 repainted, then children being painted over them. Windows only.}
88 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
89 a complete redraw of the window whenever it is resized instead of redrawing
90 just the part of the window affected by resizing. Note that this was the
91 behaviour by default before 2.5.1 release and that if you experience redraw
92 problems with code which previously used to work you may want to try this.
93 Currently this style applies on GTK+ 2 and Windows only, and full repainting is always
94 done on other platforms.}

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

131 \membersection{wxWindow::wxWindow}\label{wxwindowctor}
132
133 \func{}{wxWindow}{\void}
134
135 Default constructor.
136
137 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
138 \param{const wxPoint\& }{pos = wxDefaultPosition},
139 \param{const wxSize\& }{size = wxDefaultSize},
140 \param{long }{style = 0},
141 \param{const wxString\& }{name = wxPanelNameStr}}
142
143 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
144
145 \wxheading{Parameters}
146
147 \docparam{parent}{Pointer to a parent window.}
148
149 \docparam{id}{Window identifier. If wxID\_ANY, will automatically create an identifier.}
150
151 \docparam{pos}{Window position. wxDefaultPosition indicates that wxWidgets
152 should generate a default position for the window. If using the wxWindow class directly, supply
153 an actual position.}
154
155 \docparam{size}{Window size. wxDefaultSize indicates that wxWidgets
156 should generate a default size for the window. If no suitable size can be found, the
157 window will be sized to 20x20 pixels so that the window is visible but obviously not
158 correctly sized. }
159
160 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
161
162 \docparam{name}{Window name.}
163
164
165 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
166
167 \func{}{\destruct{wxWindow}}{\void}
168
169 Destructor. Deletes all subwindows, then deletes itself. Instead of using
170 the {\bf delete} operator explicitly, you should normally
171 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
172 can delete a window only when it is safe to do so, in idle time.

180
181 \membersection{wxWindow::AcceptsFocus}\label{wxwindowacceptsfocus}
182
183 \constfunc{bool}{AcceptsFocus}{\void}
184
185 This method may be overridden in the derived classes to return \false to
186 indicate that this control doesn't accept input at all (i.e. behaves like e.g.
187 \helpref{wxStaticText}{wxstatictext}) and so doesn't need focus.
188
189 \wxheading{See also}
190
191 \helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
192
193
194 \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
195
196 \constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
197
198 This method may be overridden in the derived classes to return \false to
199 indicate that while this control can, in principle, have focus if the user
200 clicks it with the mouse, it shouldn't be included in the TAB traversal chain
201 when using the keyboard.
202
203
204 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
205
206 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
207
208 Adds a child window. This is called automatically by window creation
209 functions so should not be required by the application programmer.
210
211 Notice that this function is mostly internal to wxWidgets and shouldn't be
212 called by the user code.
213
214 \wxheading{Parameters}
215
216 \docparam{child}{Child window to add.}
217
218
219 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
220
221 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
222
223 Sets the cached best size value.
224
225
226 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
227
228 \func{virtual void}{CaptureMouse}{\void}
229
230 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
231 release the capture.
232
233 Note that wxWidgets maintains the stack of windows having captured the mouse
234 and when the mouse is released the capture returns to the window which had had
235 captured it previously and it is only really released if there were no previous
236 window. In particular, this means that you must release the mouse as many times
237 as you capture it, unless the window receives
238 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
239
240 Any application which captures the mouse in the beginning of some operation
241 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
242 and cancel this operation when it receives the event. The event handler must
243 not recapture mouse.

270
271
272 \membersection{wxWindow::Centre}\label{wxwindowcentre}
273
274 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
275
276 Centres the window.
277
278 \wxheading{Parameters}
279
280 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
281 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
282 if you want to center the window on the entire screen and not on its
283 parent window.}
284
285 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
286 (it has no effect).
287
288 \wxheading{Remarks}
289
290 If the window is a top level one (i.e. doesn't have a parent), it will be
291 centered relative to the screen anyhow.

300 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
301
302 Centres the window on its parent. This is a more readable synonym for
303 \helpref{Centre}{wxwindowcentre}.
304
305 \wxheading{Parameters}
306
307 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
308 or {\tt wxBOTH}.}
309
310 \wxheading{Remarks}
311
312 This methods provides for a way to center top level windows over their
313 parents instead of the entire screen. If there is no parent or if the
314 window is not a top level window, then behaviour is the same as
315 \helpref{wxWindow::Centre}{wxwindowcentre}.

322 \membersection{wxWindow::CentreOnScreen}\label{wxwindowcentreonscreen}
323
324 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
325
326 Centres the window on screen. This only works for top level windows -
327 otherwise, the window will still be centered on its parent.
328
329 \wxheading{Parameters}
330
331 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

344 cause an erase background event to be generated.
345
346
347 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}

352 modifying its parameters.}
353
354 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
355
356 Converts to screen coordinates from coordinates relative to this window.
357
358 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
359 a screen coordinate will be passed out.}

374
375 \membersection{wxWindow::Close}\label{wxwindowclose}
376
377 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
378
379 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
380 handler usually tries to close the window. It doesn't close the window itself,
381 however.
382
383 \wxheading{Parameters}
384
385 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
386 of this window, {\tt true} if it cannot.}
387
388 \wxheading{Remarks}
389
390 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
391 an opportunity for the window to choose whether to destroy the window.
392 Usually it is only used with the top level windows (wxFrame and wxDialog
393 classes) as the others are not supposed to have any special OnClose() logic.
394
395 The close handler should check whether the window is being deleted forcibly,
396 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
397 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
398
399 {\it Note} that calling Close does not guarantee that the window will be
400 destroyed; but it provides a way to simulate a manual close of a window, which
401 may or may not be implemented by destroying the window. The default
402 implementation of wxDialog::OnCloseWindow does not necessarily delete the
403 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
404 the appropriate button event handler and may do anything at all.
405
406 To guarantee that the window will be destroyed, call
407 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

417
418 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
419
420 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
421
422 Converts a point or size from dialog units to pixels.
423
424 For the x dimension, the dialog units are multiplied by the average character width
425 and then divided by 4.
426
427 For the y dimension, the dialog units are multiplied by the average character height
428 and then divided by 8.
429
430 \wxheading{Remarks}
431
432 Dialog units are used for maintaining a dialog's proportions even if the font changes.
433
434 You can also use these functions programmatically. A convenience macro is defined:
435
436 {\small
437 \begin{verbatim}
438 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

495
496 \func{virtual bool}{Destroy}{\void}
497
498 Destroys the window safely. Use this function instead of the delete operator, since
499 different window classes can be destroyed differently. Frames and dialogs
500 are not destroyed immediately when this function is called -- they are added
501 to a list of windows to be deleted on idle time, when all the window's events
502 have been processed. This prevents problems with events being sent to non-existent
503 windows.
504

543 Does the window-specific updating after processing the update event.
544 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
545 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
546 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
547 implements this function as follows:
548
549 \begin{verbatim}
550 // do the window-specific processing after processing the update event
551 void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
552 {

587 disabled, all of its children are disabled as well and they are reenabled again
588 when the parent is.
589

688
689 \func{virtual void}{Fit}{\void}
690
691 Sizes the window so that it fits around its subwindows. This function won't do
692 anything if there are no subwindows and will only really work correctly if
693 sizers are used for the subwindows layout. Also, if the window has exactly one
694 subwindow it is better (faster and the result is more precise as Fit adds some
695 margin to account for fuzziness of its calculations) to call
696
697 \begin{verbatim}
698 window->SetClientSize(child->GetSize());

707
708 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
709 of a window. Mainly useful with scrolled windows to reset scrollbars after
710 sizing changes that do not trigger a size event, and/or scrolled windows without
711 an interior sizer. This function similarly won't do anything if there are no
712 subwindows.
713
714
715 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
716
717 \func{virtual void}{Freeze}{\void}
718
719 Freezes the window or, in other words, prevents any updates from taking place
720 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
721 be called to reenable window redrawing. Calls to these two functions may be
722 nested.
723
724 This method is useful for visual appearance optimization (for example, it
725 is a good idea to use it before doing many large text insertions in a row into
726 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
727 controls so it is mostly just a hint to wxWidgets and not a mandatory
728 directive.

778 application to implement (wxBG\_STYLE\_CUSTOM).

864 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
865
866 Returns the default font and colours which are used by the control. This is
867 useful if you want to use the same font or colour in your own control as in a
868 standard control -- which is a much better idea than hard coding specific
869 colours or fonts which might look completely out of place on the users
870 system, especially if it uses themes.
871
872 The \arg{variant} parameter is only relevant under Mac currently and is
873 ignore under other platforms. Under Mac, it will change the size of the
874 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
875 for more about this.
876
877 This static method is ``overridden'' in many derived classes and so calling,
878 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
879 return the values appropriate for a button which will be normally different
880 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
881
882 The \texttt{wxVisualAttributes} structure has at least the fields
883 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
884 if it was not possible to determine the default control appearance or,
885 especially for the background colour, if the field doesn't make sense as is
886 the case for \texttt{colBg} for the controls with themed background.

960 Currently this is the same as calling
961 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
962
963 One advantage of using this function compared to the static version is that
964 the call is automatically dispatched to the correct class (as usual with
965 virtual functions) and you don't have to specify the class name explicitly.
966
967 The other one is that in the future this function could return different
968 results, for example it might return a different font for an ``Ok'' button
969 than for a generic button if the users GUI is configured to show such buttons
970 in bold font. Of course, the down side is that it is impossible to call this
971 function without actually having an object to apply it to whereas the static
972 version can be used without having to create an object first.

1109 \constfunc{virtual wxString }{GetLabel}{\void}
1110
1111 Generic way of getting a label from any window, for
1112 identification purposes.
1113
1114 \wxheading{Remarks}
1115
1116 The interpretation of this function differs from class to class.
1117 For frames and dialogs, the value returned is the title. For buttons or static text controls, it is
1118 the button text. This function can be useful for meta-programs (such as testing
1119 tools or special-needs access programs) which need to identify windows
1120 by name.

1516 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1517
1518 \func{void}{InheritAttributes}{\void}
1519
1520 This function is (or should be, in case of custom controls) called during
1521 window creation to intelligently set up the window visual attributes, that is
1522 the font and the foreground and background colours.
1523
1524 By ``intelligently'' the following is meant: by default, all windows use their
1525 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1526 if some of the parents attributes are explicitly (that is, using
1527 \helpref{SetFont}{wxwindowsetfont} and not
1528 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1529 corresponding attribute hadn't been explicitly set for this window itself,
1530 then this window takes the same value as used by the parent. In addition, if
1531 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1532 to return \false, the colours will not be changed no matter what and only the
1533 font might.
1534
1535 This rather complicated logic is necessary in order to accommodate the
1536 different usage scenarios. The most common one is when all default attributes
1537 are used and in this case, nothing should be inherited as in modern GUIs
1538 different controls use different fonts (and colours) than their siblings so
1539 they can't inherit the same value from the parent. However it was also deemed
1540 desirable to allow to simply change the attributes of all children at once by
1541 just changing the font or colour of their common parent, hence in this case we
1542 do inherit the parents attributes.

1763
1764 \func{void}{MoveAfterInTabOrder}{\param{wxWindow *}{win}}
1765
1766 Moves this window in the tab navigation order after the specified \arg{win}.
1767 This means that when the user presses \texttt{TAB} key on that other window,
1768 the focus switches to this window.
1769
1770 Default tab order is the same as creation order, this function and
1771 \helpref{MoveBeforeInTabOrder()}{wxwindowmovebeforeintaborder} allow to change

1789 \membersection{wxWindow::Navigate}\label{wxwindownavigate}
1790
1791 \func{bool}{Navigate}{\param{int}{ flags = wxNavigationKeyEvent::IsForward}}
1792
1793 Performs a keyboard navigation action starting from this window. This method is
1794 equivalent to calling \helpref{NavigateIn()}{wxwindownavigatein} method on the
1795 parent window.
1796
1797 \wxheading{Parameters}

1806 \wxheading{Remarks}
1807
1808 You may wish to call this from a text control custom keypress handler to do the default
1809 navigation behaviour for the tab key, since the standard default behaviour for
1810 a multiline text control with the wxTE\_PROCESS\_TAB style is to insert a tab
1811 and not navigate to the next control.

1826
1827 If two controls are created consecutively using \texttt{wxID\_ANY} id, this
1828 function allows to retrieve the effective id of the latter control from the id
1829 of the former. This is useful for example to find the control following its
1830 \helpref{wxStaticText}{wxstatictext} label if only the id of or pointer to the

2358
2359 Pops up the given menu at the specified coordinates, relative to this
2360 window, and returns control when the user has dismissed the menu. If a
2361 menu item is selected, the corresponding menu event is generated and will be
2362 processed as usually. If the coordinates are not specified, current mouse

2415
2416 \wxheading{Remarks}
2417
2418 An event handler is an object that is capable of processing the events
2419 sent to a window. By default, the window is its own event handler, but
2420 an application may wish to substitute another, for example to allow
2421 central implementation of event-handling for a variety of different
2422 window classes.
2423
2424 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2425 an application to set up a chain of event handlers, where an event not handled by one event handler is
2426 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2427 remove the event handler.

2455 Causes this window, and all of its children recursively (except under wxGTK1
2456 where this is not implemented), to be repainted. Note that repainting doesn't
2457 happen immediately but only during the next event loop iteration, if you need

2479 repainted.
2480
2481 This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax

2490 Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
2491 will receive a hotkey event. It will receive the event even if the application is in the background
2492 and does not have the input focus because the user is working with some other application.

2495
2496 \docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If

2697
2698 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2699
2700 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2701 be called automatically when the window is resized. Please note that this only
2702 happens for the windows usually used to contain children, namely
2703 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2704 (and the classes deriving from them).
2705
2706 This method is called implicitly by
2707 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2708 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2709 manually or otherwise the window layout won't be correctly updated when its
2710 size changes.
2711
2712 \wxheading{Parameters}
2713
2714 \docparam{autoLayout}{Set this to \true if you wish the Layout function to be
2715 called automatically when the window is resized.}

2723
2724 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2725
2726 Sets the background colour of the window.
2727
2728 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2729 explanation of the difference between this method and
2730 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2731
2732 \wxheading{Parameters}
2733
2734 \docparam{colour}{The colour to be used as the background colour, pass
2735 {\tt wxNullColour} to reset to the default colour.}
2736
2737 \wxheading{Remarks}
2738
2739 The background colour is usually painted by the default\rtfsp
2740 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2741 under Windows and automatically under GTK.
2742
2743 Note that setting the background colour does not cause an immediate refresh, so you
2744 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2745 calling this function.
2746
2747 Using this function will disable attempts to use themes for this
2748 window, if the system supports them. Use with care since usually the
2749 themes represent the appearance chosen by the user to be used for all
2750 applications on the system.

2765
2766 Sets the background style of the window. The background style indicates
2767 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2768 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2769 application to implement (wxBG\_STYLE\_CUSTOM).
2770
2771 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
2772 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

2782
2783 \func{void}{SetInitialSize}{\param{const wxSize\& }{size = wxDefaultSize}}
2784
2785 A {\it smart} SetSize that will fill in default size components with the
2786 window's {\it best} size values. Also sets the window's minsize to
2787 the value passed in for use with sizers. This means that if a full or
2788 partial size is passed to this function then the sizers will use that
2789 size instead of the results of GetBestSize to determine the minimum
2790 needs of the window for layout.
2791
2792 Most controls will use this to set their initial size, and their min
2793 size to the passed in value (if any.)

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.}

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.

2848
2849 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's

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.

2917 \wxheading{Parameters}
2918
2919 \docparam{handler}{Specifies the handler to be set.}
2920
2921 \wxheading{Remarks}
2922
2923 An event handler is an object that is capable of processing the events
2924 sent to a window. By default, the window is its own event handler, but
2925 an application may wish to substitute another, for example to allow
2926 central implementation of event-handling for a variety of different
2927 window classes.
2928
2929 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2930 this sets up a chain of event handlers, where an event not handled by one event handler is
2931 handed to the next one in the chain.

2954 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2955 events are propagated upwards to the window parent recursively until a handler
2956 for them is found. Using this style allows to prevent them from being
2957 propagated beyond this window. Notice that wxDialog has this style on by
2958 default for the reasons explained in the
2959 \helpref{event processing overview}{eventprocessing}.}
2960 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2961 window from being used as an implicit parent for the dialogs which were
2962 created without a parent. It is useful for the windows which can disappear at
2963 any moment as creating children of such windows results in fatal problems.}
2964 \twocolitem{\windowstyle{wxWS\_EX\_CONTEXTHELP}}{Under Windows, puts a query
2965 button on the caption. When pressed, Windows will go into a context-sensitive
2966 help mode and wxWidgets will send a wxEVT\_HELP event if the user clicked on an

2968 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2969 these two styles are automatically turned of if this one is used.}

2994 This function is called by wxWidgets keyboard navigation code when the user
2995 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).

3007 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3008 explanations.
3009
3010 Please notice that the given font is \emph{not} automatically used for

3213 Let's say you wish to display 50 lines of text, using the same font.
3214 The window is sized so that you can only see 16 lines at a time.
3215
3216 You would use:
3217
3218 {\small%
3219 \begin{verbatim}
3220 SetScrollbar(wxVERTICAL, 0, 16, 50);
3221 \end{verbatim}
3222 }
3223
3224 Note that with the window at this size, the thumb position can never go
3225 above 50 minus 16, or 34.
3226
3227 You can determine how many lines are currently visible by dividing the current view
3228 size by the character height in pixels.
3229
3230 When defining your own scrollbar behaviour, you will always need to recalculate
3231 the scrollbar settings when the window size changes. You could therefore put your
3232 scrollbar calculations and SetScrollbar
3233 call into a function named AdjustScrollbars, which can be called initially and also
3234 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3260
3261 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3262 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3263 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3264 value has to be adjusted when the window is resized, since the page size will have changed.
3265
3266 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3267 the thumb changes size to reflect the page size relative to the length of the document. When the
3268 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3269 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3270 disappear.
3271
3272 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3273 handling of pages and ranges.

3328
3329 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3330 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3331 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3332 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3333 and usually the scrollbar will be automatically hidden.

3437 If an existing layout constraints object is already owned by the
3438 window, it will be deleted if the deleteOld parameter is true.
3439
3440 Note that this function will also call

3475 This function tells a window if it should use the system's "theme" code
3476 to draw the windows' background instead if its own background drawing
3477 code. This does not always have any effect since the underlying platform
3478 obviously needs to support the notion of themes in user defined windows.
3479 One such platform is GTK+ where windows can have (very colourful) backgrounds
3480 defined by a user's selected theme.

3728 Notice that this function doesn't invalidate any area of the window so
3729 nothing happens if nothing has been invalidated (i.e. marked as requiring
3730 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3731 immediately redraw the window unconditionally.

3736 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3737
3738 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3739 the window. The particular implementation depends on the window; for
3740 example a wxToolBar will send an update UI event for each toolbar button,
3741 and a wxFrame will send an update UI event for each menubar menu item.
3742 You can call this function from your application to ensure that your
3743 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3744 are concerned). This may be necessary if you have called
3745 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3746 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3747 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3748
3749 {\it flags} should be a bitlist of one or more of the following values.
3750
3751 \begin{verbatim}
3752 enum wxUpdateUI
3753 {
3754 wxUPDATE_UI_NONE = 0x0000, // No particular value
3755 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3756 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3757 };
3758 \end{verbatim}
3759
3760 If you are calling this function from an OnInternalIdle or OnIdle
3761 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3762 this tells the window to only update the UI elements that need
3763 to be updated in idle time. Some windows update their elements
3764 only when necessary, for example when a menu is about to be shown.
3765 The following is an example of how to call UpdateWindowUI from
3766 an idle function.
3767
3768 \begin{verbatim}
3769 void MyWindow::OnInternalIdle()
3770 {
3771 if (wxUpdateUIEvent::CanUpdate(this))
3772 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3773 }
3774 \end{verbatim}

3784
3785 \func{virtual bool}{Validate}{\void}
3786
3787 Validates the current values of the child controls using their validators.
3788
3789 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3790 the method will also call Validate() of all child windows.
3791
3792 \wxheading{Return value}
3793
3794 Returns {\tt false} if any of the validations failed.
