1 \section{\class{wxWindow}}\label{wxwindow}
2
3 wxWindow is the base class for all windows and represents any visible object on
4 screen. All controls, top level windows and so on are windows. Sizers and
5 device contexts are not, however, as they don't appear on screen themselves.
6
7 Please note that all children of the window will be deleted automatically by
8 the destructor before the window itself is deleted which means that you don't
9 have to worry about deleting them manually. Please see the \helpref{window
10 deletion overview}{windowdeletionoverview} for more information.
11
12 Also note that in this, and many others, wxWidgets classes some
13 \texttt{GetXXX()} methods may be overloaded (as, for example,
14 \helpref{GetSize}{wxwindowgetsize} or
15 \helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
16 are non-virtual because having multiple virtual functions with the same name
17 results in a virtual function name hiding at the derived class level (in
18 English, this means that the derived class has to override all overloaded
19 variants if it overrides any of them). To allow overriding them in the derived
20 class, wxWidgets uses a unique protected virtual \texttt{DoGetXXX()} method
21 and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
22 changes the behaviour of the latter.

33 \wxheading{Window styles}
34
35 The following styles can apply to all windows, although they will not always make sense for a particular
36 window class or on all platforms.
37
38 \twocolwidtha{5cm}%
39 \begin{twocollist}\itemsep=0pt
40 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
41 for this style. }
42 \twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows and Mac only.}
43 \twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
44 \twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
45 \twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control. Windows only. }
46 \twocolitem{\windowstyle{wxNO\_BORDER}}{Displays no border, overriding the default border style for the window.}
47 \twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
48 events. Windows only.}
49 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
50 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that
51 the window wants to get all char/key events for all keys - even for
52 keys like TAB or ENTER which are usually used for dialog navigation
53 and which wouldn't be generated without this style. If you need to
54 use this style in order to get the arrows or etc., but would still like to have
55 normal keyboard navigation take place, you should create and send a
56 wxNavigationKeyEvent in response to the key events for Tab and
57 Shift-Tab.}
58 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
59 the window completely when its size is changed - you will have to repaint the
60 new window area manually if you use this style. Currently only has an effect for
61 Windows.}
62 \twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
63 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
64 \twocolitem{\windowstyle{wxALWAYS\_SHOW\_SB}}{If a window has scrollbars,
65 disable them instead of hiding them when they are not needed (i.e. when the
66 size of the window is big enough to not require the scrollbars to navigate it).
67 This style is currently only implemented for wxMSW and wxUniversal and does
68 nothing on the other platforms.}
69 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
70 repainted, then children being painted over them. Windows only.}
71 \twocolitem{\windowstyle{wxFULL\_REPAINT\_ON\_RESIZE}}{Use this style to force
72 a complete redraw of the window whenever it is resized instead of redrawing
73 just the part of the window affected by resizing. Note that this was the
74 behaviour by default before 2.5.1 release and that if you experience redraw
75 problems with the code which previously used to work you may want to try this.}

80 \wxheading{Extra window styles}
81
82 The following are extra styles, set using \helpref{wxWindow::SetExtraStyle}{wxwindowsetextrastyle}.
83
84 \twocolwidtha{5cm}%
85 \begin{twocollist}\itemsep=0pt
86 \twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{By default, Validate/TransferDataTo/FromWindow()
87 only work on direct children of the window (compatible behaviour). Set this flag to make them recursively
88 descend into all subwindows.}
89 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{wxCommandEvents and the objects of the derived classes are forwarded to the
90 parent window and so on recursively by default. Using this flag for the
91 given window allows to block this propagation at this window, i.e. prevent
92 the events from being propagated further upwards. Dialogs have this
93 flag on by default.}
94 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{Don't use this window as an implicit parent for the other windows: this must
95 be used with transient windows as otherwise there is the risk of creating a
96 dialog/frame with this window as a parent which would lead to a crash if the
97 parent is destroyed before the child.}
98 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_IDLE}}{This window should always process idle events, even
99 if the mode set by \helpref{wxIdleEvent::SetMode}{wxidleeventsetmode} is wxIDLE\_PROCESS\_SPECIFIED.}
100 \twocolitem{\windowstyle{wxWS\_EX\_PROCESS\_UI\_UPDATES}}{This window should always process UI update events,
101 even if the mode set by \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} is wxUPDATE\_UI\_PROCESS\_SPECIFIED.}

115 Default constructor.
116
117 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
118 \param{const wxPoint\& }{pos = wxDefaultPosition},
119 \param{const wxSize\& }{size = wxDefaultSize},
120 \param{long }{style = 0},
121 \param{const wxString\& }{name = wxPanelNameStr}}
122
123 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
124
125 \wxheading{Parameters}
126
127 \docparam{parent}{Pointer to a parent window.}
128
129 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
130
131 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWidgets
132 should generate a default position for the window. If using the wxWindow class directly, supply
133 an actual position.}
134
135 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWidgets
136 should generate a default size for the window. If no suitable size can be found, the
137 window will be sized to 20x20 pixels so that the window is visible but obviously not
138 correctly sized. }
139
140 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
141
142 \docparam{name}{Window name.}
143
144
145 \membersection{wxWindow::\destruct{wxWindow}}\label{wxwindowdtor}
146
147 \func{}{\destruct{wxWindow}}{\void}
148
149 Destructor. Deletes all subwindows, then deletes itself. Instead of using
150 the {\bf delete} operator explicitly, you should normally
151 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWidgets
152 can delete a window only when it is safe to do so, in idle time.

161 \membersection{wxWindow::AddChild}\label{wxwindowaddchild}
162
163 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
164
165 Adds a child window. This is called automatically by window creation
166 functions so should not be required by the application programmer.
167
168 Notice that this function is mostly internal to wxWidgets and shouldn't be
169 called by the user code.
170
171 \wxheading{Parameters}
172
173 \docparam{child}{Child window to add.}
174
175
176 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
177
178 \func{virtual void}{CaptureMouse}{\void}
179
180 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
181 release the capture.
182
183 Note that wxWidgets maintains the stack of windows having captured the mouse
184 and when the mouse is released the capture returns to the window which had had
185 captured it previously and it is only really released if there were no previous
186 window. In particular, this means that you must release the mouse as many times
187 as you capture it.

214
215 \membersection{wxWindow::Centre}\label{wxwindowcentre}
216
217 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
218
219 Centres the window.
220
221 \wxheading{Parameters}
222
223 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
224 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
225 if you want to center the window on the entire screen and not on its
226 parent window.}
227
228 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
229 (it has no effect).
230
231 \wxheading{Remarks}
232
233 If the window is a top level one (i.e. doesn't have a parent), it will be
234 centered relative to the screen anyhow.

244
245 Centres the window on its parent. This is a more readable synonym for
246 \helpref{Centre}{wxwindowcentre}.
247
248 \wxheading{Parameters}
249
250 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
251 or {\tt wxBOTH}.}
252
253 \wxheading{Remarks}
254
255 This methods provides for a way to center top level windows over their
256 parents instead of the entire screen. If there is no parent or if the
257 window is not a top level window, then behaviour is the same as
258 \helpref{wxWindow::Centre}{wxwindowcentre}.

266
267 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
268
269 Centres the window on screen. This only works for top level windows -
270 otherwise, the window will still be centered on its parent.
271
272 \wxheading{Parameters}
273
274 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

317
318 \membersection{wxWindow::Close}\label{wxwindowclose}
319
320 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
321
322 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
323 handler usually tries to close the window. It doesn't close the window itself,
324 however.
325
326 \wxheading{Parameters}
327
328 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
329 of this window, {\tt true} if it cannot.}
330
331 \wxheading{Remarks}
332
333 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
334 an opportunity for the window to choose whether to destroy the window.
335 Usually it is only used with the top level windows (wxFrame and wxDialog
336 classes) as the others are not supposed to have any special OnClose() logic.
337
338 The close handler should check whether the window is being deleted forcibly,
339 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
340 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
341
342 {\it Note} that calling Close does not guarantee that the window will be
343 destroyed; but it provides a way to simulate a manual close of a window, which
344 may or may not be implemented by destroying the window. The default
345 implementation of wxDialog::OnCloseWindow does not necessarily delete the
346 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
347 the appropriate button event handler and may do anything at all.
348
349 To guarantee that the window will be destroyed, call
350 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

360
361 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
362
363 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
364
365 Converts a point or size from dialog units to pixels.
366
367 For the x dimension, the dialog units are multiplied by the average character width
368 and then divided by 4.
369
370 For the y dimension, the dialog units are multiplied by the average character height
371 and then divided by 8.
372
373 \wxheading{Remarks}
374
375 Dialog units are used for maintaining a dialog's proportions even if the font changes.
376
377 You can also use these functions programmatically. A convenience macro is defined:
378
379 {\small
380 \begin{verbatim}
381 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

440
441 Destroys the window safely. Use this function instead of the delete operator, since
442 different window classes can be destroyed differently. Frames and dialogs
443 are not destroyed immediately when this function is called -- they are added
444 to a list of windows to be deleted on idle time, when all the window's events
445 have been processed. This prevents problems with events being sent to non-existent
446 windows.
447

474
475 \func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}

477 Does the window-specific updating after processing the update event.
478 This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
479 in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
480 act appropriately. For example, to allow frame and dialog title updating, wxWidgets

517
518 \func{virtual bool}{Enable}{\param{bool}{ enable = {\tt true}}}
519
520 Enable or disable the window for user input. Note that when a parent window is
521 disabled, all of its children are disabled as well and they are reenabled again
522 when the parent is.

621
622 \func{virtual void}{Fit}{\void}
623
624 Sizes the window so that it fits around its subwindows. This function won't do
625 anything if there are no subwindows and will only really work correctly if the
626 sizers are used for the subwindows layout. Also, if the window has exactly one
627 subwindow it is better (faster and the result is more precise as Fit adds some
628 margin to account for fuzziness of its calculations) to call
629
630 \begin{verbatim}

642 of a window. Mainly useful with scrolled windows to reset scrollbars after
643 sizing changes that do not trigger a size event, and/or scrolled windows without
644 an interior sizer. This function similarly won't do anything if there are no
645 subwindows.

648 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}

652 Freezes the window or, in other words, prevents any updates from taking place
653 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
654 be called to reenable window redrawing. Calls to these two functions may be
655 nested.
656
657 This method is useful for visual appearance optimization (for example, it
658 is a good idea to use it before doing many large text insertions in a row into
659 a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
660 controls so it is mostly just a hint to wxWidgets and not a mandatory

683
684 This method is similar to \helpref{GetBestSize}{wxwindowgetbestsize}, except
685 in one thing. GetBestSize should return the minimum untruncated size of the
686 window, while this method will return the largest of BestSize and any user
687 specified minimum size. ie. it is the minimum size the window should currently

708 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
709 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
710 application to implement (wxBG\_STYLE\_CUSTOM).
711
712 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom
713 background, such as a tiled bitmap. Currently the style has no effect on other platforms.

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

789
790 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
791
792 Returns the default font and colours which are used by the control. This is
793 useful if you want to use the same font or colour in your own control as in a
794 standard control -- which is a much better idea than hard coding specific
795 colours or fonts which might look completely out of place on the users
796 system, especially if it uses themes.
797
798 The \arg{variant} parameter is only relevant under Mac currently and is
799 ignore under other platforms. Under Mac, it will change the size of the
800 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
801 for more about this.
802
803 This static method is ``overridden'' in many derived classes and so calling,
804 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
805 return the values appropriate for a button which will be normally different
806 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
807
808 The \texttt{wxVisualAttributes} structure has at least the fields
809 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
810 if it was not possible to determine the default control appearance or,
811 especially for the background colour, if the field doesn't make sense as is
812 the case for \texttt{colBg} for the controls with themed background.

882
883 Currently this is the same as calling
884 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
885
886 One advantage of using this function compared to the static version is that
887 the call is automatically dispatched to the correct class (as usual with
888 virtual functions) and you don't have to specify the class name explicitly.
889
890 The other one is that in the future this function could return different
891 results, for example it might return a different font for an ``Ok'' button
892 than for a generic button if the users GUI is configured to show such buttons
893 in bold font. Of course, the down side is that it is impossible to call this
894 function without actually having an object to apply it to whereas the static
895 version can be used without having to create an object first.

1316 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1317
1318 \func{void}{InheritAttributes}{\void}
1319
1320 This function is (or should be, in case of custom controls) called during
1321 window creation to intelligently set up the window visual attributes, that is
1322 the font and the foreground and background colours.
1323
1324 By ``intelligently'' the following is meant: by default, all windows use their
1325 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1326 if some of the parents attributes are explicitly (that is, using
1327 \helpref{SetFont}{wxwindowsetfont} and not
1328 \helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
1329 corresponding attribute hadn't been explicitly set for this window itself,
1330 then this window takes the same value as used by the parent. In addition, if
1331 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1332 to return \false, the colours will not be changed no matter what and only the
1333 font might.
1334
1335 This rather complicated logic is necessary in order to accommodate the
1336 different usage scenarios. The most common one is when all default attributes
1337 are used and in this case, nothing should be inherited as in modern GUIs
1338 different controls use different fonts (and colours) than their siblings so
1339 they can't inherit the same value from the parent. However it was also deemed
1340 desirable to allow to simply change the attributes of all children at once by
1341 just changing the font or colour of their common parent, hence in this case we
1342 do inherit the parents attributes.

2141 An event handler is an object that is capable of processing the events
2142 sent to a window. By default, the window is its own event handler, but
2143 an application may wish to substitute another, for example to allow
2144 central implementation of event-handling for a variety of different
2145 window classes.
2146
2147 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
2148 an application to set up a chain of event handlers, where an event not handled by one event handler is
2149 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
2150 remove the event handler.

2413
2414 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2415 be called automatically when the window is resized. It is called implicitly by
2416 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2417 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2418 manually or otherwise the window layout won't be correctly updated when its
2419 size changes.
2420
2421 \wxheading{Parameters}
2422
2423 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called

2435 Sets the background colour of the window.
2436
2437 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2438 explanation of the difference between this method and
2439 \helpref{SetOwnBackgroundColour}{wxwindowsetownbackgroundcolour}.
2440
2441 \wxheading{Parameters}
2442
2443 \docparam{colour}{The colour to be used as the background colour, pass
2444 {\tt wxNullColour} to reset to the default colour.}
2445
2446 \wxheading{Remarks}
2447
2448 The background colour is usually painted by the default\rtfsp
2449 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2450 under Windows and automatically under GTK.
2451
2452 Note that setting the background colour does not cause an immediate refresh, so you
2453 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2454 calling this function.
2455
2456 Using this function will disable attempts to use themes for this
2457 window, if the system supports them. Use with care since usually the
2458 themes represent the appearance chosen by the user to be used for all
2459 applications on the system.

2475 Sets the background style of the window. The background style indicates
2476 whether background colour should be determined by the system (wxBG\_STYLE\_SYSTEM),
2477 be set to a specific colour (wxBG\_STYLE\_COLOUR), or should be left to the
2478 application to implement (wxBG\_STYLE\_CUSTOM).
2479
2480 On GTK+, use of wxBG\_STYLE\_CUSTOM allows the flicker-free drawing of a custom

2496 the value passed in for use with sizers. This means that if a full or
2497 partial size is passed to this function then the sizers will use that
2498 size instead of the results of GetBestSize to determine the minimum

2520 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2521
2522 This sets the size of the window client area in pixels. Using this function to size a window
2523 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2524 worry about what dimensions the border or title bar have when trying to fit the window
2525 around panel items, for example.

2579 will then own the object, and will take care of its deletion.
2580 If an existing layout constraints object is already owned by the
2581 window, it will be deleted.
2582

2590 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2591 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2592 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2673 \docparam{handler}{Specifies the handler to be set.}
2674
2675 \wxheading{Remarks}
2676
2677 An event handler is an object that is capable of processing the events
2678 sent to a window. By default, the window is its own event handler, but
2679 an application may wish to substitute another, for example to allow
2680 central implementation of event-handling for a variety of different
2681 window classes.
2682
2683 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2684 this sets up a chain of event handlers, where an event not handled by one event handler is
2685 handed to the next one in the chain.

2708 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2709 events are propagated upwards to the window parent recursively until a handler
2710 for them is found. Using this style allows to prevent them from being
2711 propagated beyond this window. Notice that wxDialog has this style on by
2712 default for the reasons explained in the
2713 \helpref{event processing overview}{eventprocessing}.}
2714 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
2715 window from being used as an implicit parent for the dialogs which were
2716 created without a parent. It is useful for the windows which can disappear at
2717 any moment as creating children of such windows results in fatal problems.}
2718 \twocolitem{\windowstyle{wxFRAME\_EX\_CONTEXTHELP}}{Under Windows, puts a query button on the
2719 caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send
2720 a wxEVT\_HELP event if the user clicked on an application window.
2721 This style cannot be used together with wxMAXIMIZE\_BOX or wxMINIMIZE\_BOX, so
2722 you should use the style of
2723 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2885
2886 Let's say you wish to display 50 lines of text, using the same font.
2887 The window is sized so that you can only see 16 lines at a time.
2888
2889 You would use:
2890
2891 {\small%
2892 \begin{verbatim}
2893 SetScrollbar(wxVERTICAL, 0, 16, 50);
2894 \end{verbatim}
2895 }
2896
2897 Note that with the window at this size, the thumb position can never go
2898 above 50 minus 16, or 34.
2899
2900 You can determine how many lines are currently visible by dividing the current view
2901 size by the character height in pixels.
2902
2903 When defining your own scrollbar behaviour, you will always need to recalculate
2904 the scrollbar settings when the window size changes. You could therefore put your
2905 scrollbar calculations and SetScrollbar
2906 call into a function named AdjustScrollbars, which can be called initially and also
2907 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2930
2931 \wxheading{Remarks}
2932
2933 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2934 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2935 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2936 value has to be adjusted when the window is resized, since the page size will have changed.
2937
2938 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2939 the thumb changes size to reflect the page size relative to the length of the document. When the
2940 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2941 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2942 disappear.
2943
2944 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2945 handling of pages and ranges.

3000
3001 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
3002 object length of the scrollbar. If you are implementing a scrolling window, for example, you
3003 would adjust the scroll range when the window is resized, by subtracting the window view size from the
3004 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
3005 and usually the scrollbar will be automatically hidden.

3186 This function tells a window if it should use the system's "theme" code
3187 to draw the windows' background instead if its own background drawing
3188 code. This does not always have any effect since the underlying platform
3189 obviously needs to support the notion of themes in user defined windows.
3190 One such platform is GTK+ where windows can have (very colourful) backgrounds
3191 defined by a user's selected theme.
3192
3193 Dialogs, notebook pages and the status bar have this flag set to true
3194 by default so that the default look and feel is simulated best.

3265 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
3266
3267 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
3268
3269 Sets the style of the window. Please note that some styles cannot be changed
3270 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
3271 be called after changing the others for the change to take place immediately.

3281
3282 \func{void}{SetWindowVariant}{\param{wxWindowVariant}{variant}}
3283
3284 This function can be called under all platforms but only does anything under
3285 Mac OS X 10.3+ currently. Under this system, each of the standard control can
3286 exist in several sizes which correspond to the elements of wxWindowVariant
3287 enum:
3288 \begin{verbatim}
3289 enum wxWindowVariant
3290 {
3291 wxWINDOW_VARIANT_NORMAL, // Normal size
3292 wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )
3293 wxWINDOW_VARIANT_MINI, // Mini size (about 33 % smaller than normal )
3294 wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
3295 };
3296 \end{verbatim}
3297
3298 By default the controls use the normal size, of course, but this function can
3299 be used to change this.

3305
3306 Return \true from here to allow the colours of this window to be changed by
3307 \helpref{InheritAttributes}{wxwindowinheritattributes}, returning \false
3308 forbids inheriting them from the parent window.
3309
3310 The base class version returns \false, but this method is overridden in
3311 \helpref{wxControl}{wxcontrol} where it returns \true.
3312
3313
3314 \membersection{wxWindow::Show}\label{wxwindowshow}
3315
3316 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
3317
3318 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
3319 for a top level window if you want to bring it to top, although this is not
3320 needed if Show() is called immediately after the frame creation.
3321
3322 \wxheading{Parameters}
3323
3324 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
3325
3326 \wxheading{Return value}
3327
3328 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
3329 done because it already was in the requested state.

3340
3341 Reenables window updating after a previous call to

3343 exactly the same number of times as \helpref{Freeze}{wxwindowfreeze}.

3349
3350 Transfers values from child controls to data areas specified by their validators. Returns
3351 {\tt false} if a transfer failed.
3352
3353 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3354 the method will also call TransferDataFromWindow() of all child windows.

3404 \membersection{wxWindow::Update}\label{wxwindowupdate}
3405
3406 \func{virtual void}{Update}{\void}
3407
3408 Calling this method immediately repaints the invalidated area of the window
3409 while this would usually only happen when the flow of control returns to the
3410 event loop. Notice that this function doesn't refresh the window and does
3411 nothing if the window hadn't been already repainted. Use
3412 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3413 window unconditionally.
3414
3415
3416 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3417
3418 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3419
3420 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3421 the window. The particular implementation depends on the window; for
3422 example a wxToolBar will send an update UI event for each toolbar button,
3423 and a wxFrame will send an update UI event for each menubar menu item.
3424 You can call this function from your application to ensure that your
3425 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3426 are concerned). This may be necessary if you have called
3427 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3428 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3429 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3430
3431 {\it flags} should be a bitlist of one or more of the following values.
3432
3433 \begin{verbatim}
3434 enum wxUpdateUI
3435 {
3436 wxUPDATE_UI_NONE = 0x0000, // No particular value
3437 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3438 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3439 };
3440 \end{verbatim}
3441
3442 If you are calling this function from an OnInternalIdle or OnIdle
3443 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3444 this tells the window to only update the UI elements that need
3445 to be updated in idle time. Some windows update their elements
3446 only when necessary, for example when a menu is about to be shown.
3447 The following is an example of how to call UpdateWindowUI from
3448 an idle function.
3449
3450 \begin{verbatim}
3451 void MyWindow::OnInternalIdle()
3452 {
3453 if (wxUpdateUIEvent::CanUpdate(this))
3454 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3455 }

3470
3471 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3472 the method will also call Validate() of all child windows.
3473
3474 \wxheading{Return value}
