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.}

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

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

194 \helpref{AcceptsFocusFromKeyboard}{wxwindowacceptsfocusfromkeyboard}
195
196
197 \membersection{wxWindow::AcceptsFocusFromKeyboard}\label{wxwindowacceptsfocusfromkeyboard}
198
199 \constfunc{bool}{AcceptsFocusFromKeyboard}{\void}
200
201 This method may be overridden in the derived classes to return \false to
202 indicate that while this control can, in principle, have focus if the user
203 clicks it with the mouse, it shouldn't be included in the TAB traversal chain
204 when using the keyboard.
205
206
207 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
208
209 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
210
211 Adds a child window. This is called automatically by window creation
212 functions so should not be required by the application programmer.
213
214 Notice that this function is mostly internal to wxWidgets and shouldn't be
215 called by the user code.
216
217 \wxheading{Parameters}
218
219 \docparam{child}{Child window to add.}
220
221
222 \membersection{wxWindow::AlwaysShowScrollbars}\label{wxwindowalwaysshowscrollbars}
223
224 \func{void}{AlwaysShowScrollbars}{\param{bool}{ hflag}, \param{bool}{ vflag}}
225
226 Call this function to force one or both scrollbars to be always shown, even if
227 the window is big enough to show its entire contents without scrolling.
228
229 \newsince{2.9.0}
230
231 \wxheading{Parameters}
232
233 \docparam{hflag}{Whether the horizontal scroll bar should always be visible.}
234
235 \docparam{vflag}{Whether the vertical scroll bar should always be visible.}
236
237 \wxheading{Remarks}
238
239 This function is currently only implemented under Mac/Carbon.
240
241
242 \membersection{wxWindow::CacheBestSize}\label{wxwindowcachebestsize}
243
244 \constfunc{void}{CacheBestSize}{\param{const wxSize\& }{size}}
245
246 Sets the cached best size value.
247
248
249 \membersection{wxWindow::CanSetTransparent}\label{wxwindowcansettransparent}
250
251 \func{bool}{CanSetTransparent}{\void}
252
253 Returns \true if the system supports transparent windows and calling
254 \helpref{SetTransparent}{wxwindowsettransparent} may succeed. If this function
255 returns \false, transparent windows are definitely not supported by the current
256 system.
257
258
259 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
260
261 \func{virtual void}{CaptureMouse}{\void}
262
263 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
264 release the capture.
265
266 Note that wxWidgets maintains the stack of windows having captured the mouse
267 and when the mouse is released the capture returns to the window which had had
268 captured it previously and it is only really released if there were no previous
269 window. In particular, this means that you must release the mouse as many times
270 as you capture it, unless the window receives
271 the \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent} event.
272
273 Any application which captures the mouse in the beginning of some operation
274 {\em must} handle \helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
275 and cancel this operation when it receives the event. The event handler must
276 not recapture mouse.

287
288 A synonym for \helpref{Centre}{wxwindowcentre}.
289
290
291 \membersection{wxWindow::CenterOnParent}\label{wxwindowcenteronparent}
292

296
297
298 \membersection{wxWindow::Centre}\label{wxwindowcentre}
299
300 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
301
302 Centres the window.
303
304 \wxheading{Parameters}
305
306 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
307 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
308 if you want to center the window on the entire screen and not on its
309 parent window.}
310
311 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
312 (it has no effect).
313
314 \wxheading{Remarks}
315
316 If the window is a top level one (i.e. doesn't have a parent), it will be
317 centered relative to the screen anyhow.

324 \membersection{wxWindow::CentreOnParent}\label{wxwindowcentreonparent}
325
326 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
327
328 Centres the window on its parent. This is a more readable synonym for
329 \helpref{Centre}{wxwindowcentre}.
330
331 \wxheading{Parameters}
332
333 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
334 or {\tt wxBOTH}.}
335
336 \wxheading{Remarks}
337
338 This methods provides for a way to center top level windows over their
339 parents instead of the entire screen. If there is no parent or if the
340 window is not a top level window, then behaviour is the same as
341 \helpref{wxWindow::Centre}{wxwindowcentre}.

349
350 \func{void}{ClearBackground}{\void}
351
352 Clears the window by filling it with the current background colour. Does not
353 cause an erase background event to be generated.
354
355
356 \membersection{wxWindow::ClientToScreen}\label{wxwindowclienttoscreen}
357
358 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}

371 a screen coordinate will be passed out.}
372
373 \docparam{pt}{The client position for the second form of the function.}
374
375 \pythonnote{In place of a single overloaded method name, wxPython

383
384 \membersection{wxWindow::Close}\label{wxwindowclose}
385
386 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
387
388 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
389 handler usually tries to close the window. It doesn't close the window itself,
390 however.
391
392 \wxheading{Parameters}
393
394 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
395 of this window, {\tt true} if it cannot.}
396
397 \wxheading{Remarks}
398
399 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
400 an opportunity for the window to choose whether to destroy the window.
401 Usually it is only used with the top level windows (wxFrame and wxDialog
402 classes) as the others are not supposed to have any special OnClose() logic.
403
404 The close handler should check whether the window is being deleted forcibly,
405 using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}, in which case it
406 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
407
408 {\it Note} that calling Close does not guarantee that the window will be
409 destroyed; but it provides a way to simulate a manual close of a window, which
410 may or may not be implemented by destroying the window. The default
411 implementation of wxDialog::OnCloseWindow does not necessarily delete the
412 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
413 the appropriate button event handler and may do anything at all.
414
415 To guarantee that the window will be destroyed, call
416 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

426
427 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
428
429 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
430
431 Converts a point or size from dialog units to pixels.
432
433 For the x dimension, the dialog units are multiplied by the average character width
434 and then divided by 4.
435
436 For the y dimension, the dialog units are multiplied by the average character height
437 and then divided by 8.
438
439 \wxheading{Remarks}
440
441 Dialog units are used for maintaining a dialog's proportions even if the font changes.
442

508 different window classes can be destroyed differently. Frames and dialogs
509 are not destroyed immediately when this function is called -- they are added

511 have been processed. This prevents problems with events being sent to non-existent
512 windows.

552 Does the window-specific updating after processing the update event.
553 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
554 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
555 act appropriately. For example, to allow frame and dialog title updating, wxWidgets
556 implements this function as follows:
557
558 \begin{verbatim}
559 // do the window-specific processing after processing the update event
560 void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)

698
699 \func{virtual void}{Fit}{\void}
700
701 Sizes the window so that it fits around its subwindows. This function won't do
702 anything if there are no subwindows and will only really work correctly if
703 sizers are used for the subwindows layout. Also, if the window has exactly one
704 subwindow it is better (faster and the result is more precise as Fit adds some
705 margin to account for fuzziness of its calculations) to call
706
707 \begin{verbatim}
708 window->SetClientSize(child->GetSize());

712
713
714 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}

716 \func{virtual void}{FitInside}{\void}
717
718 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
719 of a window. Mainly useful with scrolled windows to reset scrollbars after
720 sizing changes that do not trigger a size event, and/or scrolled windows without
721 an interior sizer. This function similarly won't do anything if there are no
722 subwindows.
723
724
725 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

727 \func{virtual void}{Freeze}{\void}
728
729 Freezes the window or, in other words, prevents any updates from taking place
730 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
731 be called to reenable window redrawing. Calls to these two functions may be
732 nested but to ensure that the window is properly repainted again, you must thaw
733 it exactly as many times as you froze it.
734
735 This method is useful for visual appearance optimization (for example, it
736 is a good idea to use it before doing many large text insertions in a row into
737 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
738 controls so it is mostly just a hint to wxWidgets and not a mandatory

889
890 Returns the default font and colours which are used by the control. This is
891 useful if you want to use the same font or colour in your own control as in a
892 standard control -- which is a much better idea than hard coding specific
893 colours or fonts which might look completely out of place on the users
894 system, especially if it uses themes.
895
896 The \arg{variant} parameter is only relevant under Mac currently and is
897 ignore under other platforms. Under Mac, it will change the size of the
898 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
899 for more about this.
900
901 This static method is ``overridden'' in many derived classes and so calling,
902 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
903 return the values appropriate for a button which will be normally different
904 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
905
906 The \texttt{wxVisualAttributes} structure has at least the fields
907 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
908 if it was not possible to determine the default control appearance or,
909 especially for the background colour, if the field doesn't make sense as is
910 the case for \texttt{colBg} for the controls with themed background.

984 Currently this is the same as calling

986
987 One advantage of using this function compared to the static version is that
988 the call is automatically dispatched to the correct class (as usual with
989 virtual functions) and you don't have to specify the class name explicitly.
990
991 The other one is that in the future this function could return different
992 results, for example it might return a different font for an ``Ok'' button
993 than for a generic button if the users GUI is configured to show such buttons
994 in bold font. Of course, the down side is that it is impossible to call this
995 function without actually having an object to apply it to whereas the static
996 version can be used without having to create an object first.

1633 window creation to intelligently set up the window visual attributes, that is
1634 the font and the foreground and background colours.
1635
1636 By ``intelligently'' the following is meant: by default, all windows use their
1637 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1638 if some of the parents attributes are explicitly (that is, using
1639 \helpref{SetFont}{wxwindowsetfont} and not
1640 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1641 corresponding attribute hadn't been explicitly set for this window itself,
1642 then this window takes the same value as used by the parent. In addition, if
1643 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1644 to return \false, the colours will not be changed no matter what and only the
1645 font might.
1646
1647 This rather complicated logic is necessary in order to accommodate the
1648 different usage scenarios. The most common one is when all default attributes
1649 are used and in this case, nothing should be inherited as in modern GUIs
1650 different controls use different fonts (and colours) than their siblings so
1651 they can't inherit the same value from the parent. However it was also deemed
1652 desirable to allow to simply change the attributes of all children at once by
1653 just changing the font or colour of their common parent, hence in this case we
1654 do inherit the parents attributes.

2545
2546 An event handler is an object that is capable of processing the events
2547 sent to a window. By default, the window is its own event handler, but
2548 an application may wish to substitute another, for example to allow
2549 central implementation of event-handling for a variety of different
2550 window classes.
2551
2552 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2553 an application to set up a chain of event handlers, where an event not handled by one event handler is
2554 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

2824 \membersection{wxWindow::SetAutoLayout}\label{wxwindowsetautolayout}
2825
2826 \func{void}{SetAutoLayout}{\param{bool}{ autoLayout}}
2827
2828 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2829 be called automatically when the window is resized. Please note that this only
2830 happens for the windows usually used to contain children, namely
2831 \helpref{wxPanel}{wxpanel} and \helpref{wxTopLevelWindow}{wxtoplevelwindow}
2832 (and the classes deriving from them).
2833
2834 This method is called implicitly by
2835 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2836 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2837 manually or otherwise the window layout won't be correctly updated when its
2838 size changes.
2839
2840 \wxheading{Parameters}
2841
2842 \docparam{autoLayout}{Set this to \true if you wish the Layout function to be

2851
2852 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2853
2854 Sets the background colour of the window.
2855
2856 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2857 explanation of the difference between this method and
2858 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2859
2860 \wxheading{Parameters}
2861
2862 \docparam{colour}{The colour to be used as the background colour, pass
2863 {\tt wxNullColour} to reset to the default colour.}
2864
2865 \wxheading{Remarks}
2866
2867 The background colour is usually painted by the default\rtfsp
2868 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2869 under Windows and automatically under GTK.
2870
2871 Note that setting the background colour does not cause an immediate refresh, so you
2872 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2873 calling this function.
2874
2875 Using this function will disable attempts to use themes for this
2876 window, if the system supports them. Use with care since usually the
2877 themes represent the appearance chosen by the user to be used for all
2878 applications on the system.

2909
2910 This method is only implemented by ports which have support for
2911 native TAB traversal (such as GTK+ 2.0). It is called by wxWidgets'
2912 container control code to give the native system a hint when
2913 doing TAB traversal. A call to this does not disable or change
2914 the effect of programmatically calling
2915 \helpref{wxWindow::SetFocus}{wxwindowsetfocus}.

2934
2935 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2936
2937 This sets the size of the window client area in pixels. Using this function to size a window
2938 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2939 worry about what dimensions the border or title bar have when trying to fit the window
2940 around panel items, for example.
2941
2942 \wxheading{Parameters}
2943
2944 \docparam{width}{The required client area width.}

2964 will then own the object, and will take care of its deletion.
2965 If an existing layout constraints object is already owned by the
2966 window, it will be deleted.
2967

2969
2970 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2971 constraints.}
2972
2973 \wxheading{Remarks}
2974
2975 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2976 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2977 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
2978 sizer will have effect.

2984 This normally does not need to be called by user code. It is called
2985 when a window is added to a sizer, and is used so the window can
2986 remove itself from the sizer when it is destroyed.

3031 \wxheading{Parameters}
3032
3033 \docparam{handler}{Specifies the handler to be set.}
3034
3035 \wxheading{Remarks}
3036
3037 An event handler is an object that is capable of processing the events
3038 sent to a window. By default, the window is its own event handler, but
3039 an application may wish to substitute another, for example to allow
3040 central implementation of event-handling for a variety of different
3041 window classes.
3042
3043 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler}
3044 since this sets up a chain of event handlers, where an event not handled by
3045 one event handler is handed to the next one in the chain.

3068 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
3069 events are propagated upwards to the window parent recursively until a handler
3070 for them is found. Using this style allows to prevent them from being
3071 propagated beyond this window. Notice that wxDialog has this style on by
3072 default for the reasons explained in the
3073 \helpref{event processing overview}{eventprocessing}.}
3074 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
3075 window from being used as an implicit parent for the dialogs which were

3108
3109 This function is called by wxWidgets keyboard navigation code when the user
3110 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
3111 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

3121 use \helpref{SetOwnFont}{wxwindowsetownfont} instead in this case and
3122 see \helpref{InheritAttributes}{wxwindowinheritattributes} for more
3123 explanations.
3124
3125 Please notice that the given font is \emph{not} automatically used for
3126 \helpref{wxPaintDC}{wxpaintdc} objects associated with this window, you need to
3127 call \helpref{wxDC::SetFont()}{wxdcsetfont} too. However this font is used by

3358 Let's say you wish to display 50 lines of text, using the same font.
3359 The window is sized so that you can only see 16 lines at a time.
3360
3361 You would use:
3362
3363 {\small%
3364 \begin{verbatim}
3365 SetScrollbar(wxVERTICAL, 0, 16, 50);
3366 \end{verbatim}
3367 }
3368
3369 Note that with the window at this size, the thumb position can never go
3370 above 50 minus 16, or 34.
3371
3372 You can determine how many lines are currently visible by dividing the current view
3373 size by the character height in pixels.
3374
3375 When defining your own scrollbar behaviour, you will always need to recalculate
3376 the scrollbar settings when the window size changes. You could therefore put your
3377 scrollbar calculations and SetScrollbar
3378 call into a function named AdjustScrollbars, which can be called initially and also
3379 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

3405
3406 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
3407 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
3408 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
3409 value has to be adjusted when the window is resized, since the page size will have changed.
3410
3411 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
3412 the thumb changes size to reflect the page size relative to the length of the document. When the
3413 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
3414 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
3415 disappear.
3416
3417 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
3418 handling of pages and ranges.

3473
3474 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3475 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3476 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3477 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3478 and usually the scrollbar will be automatically hidden.

3734 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3735
3736 This function can be called under all platforms but only does anything under
3737 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3738 exist in several sizes which correspond to the elements of wxWindowVariant
3739 enum:
3740 \begin{verbatim}
3741 enum wxWindowVariant
3742 {
3743 wxWINDOW_VARIANT_NORMAL, // Normal size
3744 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3745 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3746 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3747 };
3748 \end{verbatim}
3749
3750 By default the controls use the normal size, of course, but this function can
3751 be used to change this.

3758 Return \true from here to allow the colours of this window to be changed by
3759 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3760 forbids inheriting them from the parent window.
3761
3762 The base class version returns \false, but this method is overridden in
3763 \helpref{wxControl}{wxcontrol} where it returns \true.

3766 \membersection{wxWindow::Show}\label{wxwindowshow}
3767
3768 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3769
3770 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3771 for a top level window if you want to bring it to top, although this is not
3772 needed if Show() is called immediately after the frame creation.
3773
3774 \wxheading{Parameters}
3775
3776 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3777
3778 \wxheading{Return value}
3779
3780 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was

3791
3792 \func{virtual bool}{ShowWithEffect}{\param{wxShowEffect }{effect}, \param{unsigned }{timeout = $0$}, \param{wxDirection }{dir = wxBOTTOM}}
3793
3794 This function shows a window, like \helpref{Show()}{wxwindowshow}, but using a
3795 special visual effect if possible.
3796
3797 Possible values for \arg{effect} are:
3798 \begin{twocollist}\itemsep=0pt
3799 \twocolitem{wxSHOW\_EFFECT\_ROLL}{Roll window effect}
3800 \twocolitem{wxSHOW\_EFFECT\_SLIDE}{Sliding window effect}
3801 \twocolitem{wxSHOW\_EFFECT\_BLEND}{Fade in or out effect}
3802 \twocolitem{wxSHOW\_EFFECT\_EXPAND}{Expanding or collapsing effect}
3803 \end{twocollist}
3804
3805 For the roll and slide effects the \arg{dir} parameter specifies the animation
3806 direction: it can be one of \texttt{wxTOP}, \texttt{wxBOTTOM}, \texttt{wxLEFT}
3807 or \texttt{wxRIGHT}. For the other effects, this parameter is unused.
3808
3809 The \arg{timeout} parameter specifies the time of the animation, in
3810 milliseconds. If the default value of $0$ is used, the default animation time
3811 for the current platform is used.
3812
3813 Currently this function is only implemented in wxMSW and does the same thing as
3814 Show() in the other ports.

3935 \membersection{wxWindow::Update}\label{wxwindowupdate}
3936
3937 \func{virtual void}{Update}{\void}
3938
3939 Calling this method immediately repaints the invalidated area of the window and
3940 all of its children recursively while this would usually only happen when the
3941 flow of control returns to the event loop.
3942 Notice that this function doesn't invalidate any area of the window so
3943 nothing happens if nothing has been invalidated (i.e. marked as requiring
3944 a redraw). Use \helpref{Refresh}{wxwindowrefresh} first if you want to
3945 immediately redraw the window unconditionally.
3946
3947
3948 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3949
3950 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3951
3952 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3953 the window. The particular implementation depends on the window; for
3954 example a wxToolBar will send an update UI event for each toolbar button,
3955 and a wxFrame will send an update UI event for each menubar menu item.
3956 You can call this function from your application to ensure that your
3957 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3958 are concerned). This may be necessary if you have called
3959 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3960 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3961 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3962
3963 {\it flags} should be a bitlist of one or more of the following values.
3964
3965 \begin{verbatim}
3966 enum wxUpdateUI
3967 {
3968 wxUPDATE_UI_NONE = 0x0000, // No particular value
3969 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3970 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3971 };
3972 \end{verbatim}
3973
3974 If you are calling this function from an OnInternalIdle or OnIdle
3975 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3976 this tells the window to only update the UI elements that need
3977 to be updated in idle time. Some windows update their elements
3978 only when necessary, for example when a menu is about to be shown.
3979 The following is an example of how to call UpdateWindowUI from
3980 an idle function.
3981
3982 \begin{verbatim}
3983 void MyWindow::OnInternalIdle()
3984 {
3985 if (wxUpdateUIEvent::CanUpdate(this))
3986 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3987 }
