1 \section{\class{wxWindow}}\label{wxwindow}
2
3 wxWindow is the base class for all windows and represents any visible objecto n
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.}

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}}
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.

160
161 \membersection{wxWindow::AddChild}
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.

213
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.

243 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
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)

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}}
476
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.
523
524 \wxheading{Parameters}
525

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}
631 window->SetClientSize(child->GetSize());

634 instead of calling Fit.

639 \func{virtual void}{FitInside}{\void}
640

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}

650 \func{virtual void}{Freeze}{\void}
651
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 inserting large amount of text into a
659 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

682 \constfunc{wxSize}{GetAdjustedBestSize}{\void}
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
688 be drawn at, not the minimal size it can possibly tolerate.

708 This functions returns the best acceptable minimal size for the window. For
709 example, for a static control, it will be the minimal size such that the
710 control label is not truncated. For windows containing subwindows (typically
711 \helpref{wxPanel}{wxpanel}), the size returned by this function will be the
712 same as the size the window would have had after calling

759
760 \func{static wxVisualAttributes}{GetClassDefaultAttributes}{\param{wxWindowVariant}{ variant = \texttt{wxWINDOW\_VARIANT\_NORMAL}}}
761
762 Returns the default font and colours which are used by the control. This is
763 useful if you want to use the same font or colour in your own control as in a
764 standard control -- which is a much better idea than hard coding specific
765 colours or fonts which might look completely out of place on the users
766 system, especially if it uses themes.
767
768 The \arg{variant} parameter is only relevant under Mac currently and is
769 ignore under other platforms. Under Mac, it will change the size of the
770 returned font. See \helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}
771 for more about this.
772
773 This static method is ``overridden'' in many derived classes and so calling,
774 for example, \helpref{wxButton}{wxbutton}::GetClassDefaultAttributes() will typically
775 return the values appropriate for a button which will be normally different
776 from those returned by, say, \helpref{wxListCtrl}{wxlistctrl}::GetClassDefaultAttributes().
777
778 The \texttt{wxVisualAttributes} structure has at least the fields
779 \texttt{font}, \texttt{colFg} and \texttt{colBg}. All of them may be invalid
780 if it was not possible to determine the default control appearance or,
781 especially for the background colour, if the field doesn't make sense as is
782 the case for \texttt{colBg} for the controls with themed background.

852
853 Currently this is the same as calling
854 \helpref{GetClassDefaultAttributes}{wxwindowgetclassdefaultattributes}(\helpref{GetWindowVariant}{wxwindowgetwindowvariant}()).
855
856 One advantage of using this function compared to the static version is that
857 the call is automatically dispatched to the correct class (as usual with
858 virtual functions) and you don't have to specify the class name explicitly.
859
860 The other one is that in the future this function could return different
861 results, for example it might return a different font for an ``Ok'' button
862 than for a generic button if the users GUI is configured to show such buttons
863 in bold font. Of course, the down side is that it is impossible to call this
864 function without actually having an object to apply it to whereas the static
865 version can be used without having to create an object first.

1273 \membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
1274
1275 \func{void}{InheritAttributes}{\void}
1276
1277 This function is (or should be, in case of custom controls) called during
1278 window creation to intelligently set up the window visual attributes, that is
1279 the font and the foreground and background colours.
1280
1281 By ``intelligently'' the following is meant: by default, all windows use their
1282 own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
1283 if some of the parents attributes are explicitly (that is, using
1284 \helpref{SetFont}{wxwindowsetfont} and not
1285 \helpref{SetDefaultFont}{wxwindowsetdefaultfont}) changed \emph{and} if the
1286 corresponding attribute hadn't been explicitly set for this window itself,
1287 then this window takes the same value as used by the parent. In addition, if
1288 the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
1289 to return \false, the colours will not be changed no matter what and only the
1290 font might.
1291
1292 This rather complicated logic is necessary in order to accomodate the
1293 different usage scenarius. The most common one is when all default attributes
1294 are used and in this case, nothing should be inherited as in modern GUIs
1295 different controls use different fonts (and colours) than their siblings so
1296 they can't inherit the same value from the parent. However it was also deemed
1297 desirable to allow to simply change the attributes of all children at once by
1298 just changing the font or colour of their common parent, hence in this case we
1299 do inherit the parents attributes.

2071 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2174 \func{virtual void}{RemoveChild}{\param{wxWindow* }{child}}
2175
2176 Removes a child window. This is called automatically by window deletion

2337
2338 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
2339 be called automatically when the window is resized. It is called implicitly by
2340 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
2341 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
2342 manually or otherwise the window layout won't be correctly updated when its
2343 size changes.
2344
2345 \wxheading{Parameters}
2346
2347 \docparam{autoLayout}{Set this to {\tt true} if you wish the Layout function to be called
2348 from within wxWindow::OnSize functions.}

2356
2357 \func{virtual bool}{SetBackgroundColour}{\param{const wxColour\& }{colour}}
2358
2359 Sets the background colour of the window.
2360
2361 Please see \helpref{InheritAttributes}{wxwindowinheritattributes} for
2362 explanation of the difference between this method and
2363 \helpref{SetDefaultBackgroundColour}{wxwindowsetdefaultbackgroundcolour}.
2364
2365 \wxheading{Parameters}
2366
2367 \docparam{colour}{The colour to be used as the background colour.}
2368
2369 \wxheading{Remarks}
2370
2371 The background colour is usually painted by the default\rtfsp
2372 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2373 under Windows and automatically under GTK.
2374
2375 Note that setting the background colour does not cause an immediate refresh, so you
2376 may wish to call \helpref{wxWindow::ClearBackground}{wxwindowclearbackground} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2377 calling this function.
2378
2379 Use this function with care under GTK+ as the new appearance of the window might
2380 not look equally well when used with "Themes", i.e GTK+'s ability to change its
2381 look as the user wishes with run-time loadable modules.

2403
2404 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2405
2406 This sets the size of the window client area in pixels. Using this function to size a window
2407 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2408 worry about what dimensions the border or title bar have when trying to fit the window
2409 around panel items, for example.
2410
2411 \wxheading{Parameters}
2412
2413 \docparam{width}{The required client area width.}

2431
2432 This normally does not need to be called by user code. It is called
2433 when a window is added to a sizer, and is used so the window can
2434 remove itself from the sizer when it is destroyed.

2441 % VZ: the docs are correct, if the code doesn't behave like this, it must be
2442 % changed
2443 Sets the window's cursor. Notice that the window cursor also sets it for the
2444 children of the window implicitly.
2445
2446 The {\it cursor} may be {\tt wxNullCursor} in which case the window cursor will
2447 be reset back to default.

2460 \func{void}{SetConstraints}{\param{wxLayoutConstraints* }{constraints}}
2461
2462 Sets the window to have the given layout constraints. The window
2463 will then own the object, and will take care of its deletion.
2464 If an existing layout constraints object is already owned by the
2465 window, it will be deleted.
2466
2467 \wxheading{Parameters}
2468
2469 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2470 constraints.}
2471
2472 \wxheading{Remarks}
2473
2474 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2475 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2476 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2541
2542 \docparam{handler}{Specifies the handler to be set.}
2543
2544 \wxheading{Remarks}
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 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
2553 this sets 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.

2577 \twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
2578 events are propagated upwards to the window parent recursively until a handler
2579 for them is found. Using this style allows to prevent them from being
2580 propagated beyond this window. Notice that wxDialog has this style on by
2581 default for the reasons explained in the

2583 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2591 you should use the style of
2592 {\tt wxDEFAULT\_FRAME\_STYLE \& \textasciitilde(wxMINIMIZE\_BOX | wxMAXIMIZE\_BOX)} for the

2617 This function is called by wxWidgets keyboard navigation code when the user
2618 gives the focus to this window from keyboard (e.g. using {\tt TAB} key).
2619 By default this method simply calls \helpref{SetFocus}{wxwindowsetfocus} but

2752 Let's say you wish to display 50 lines of text, using the same font.
2753 The window is sized so that you can only see 16 lines at a time.
2754
2755 You would use:
2756
2757 {\small%
2758 \begin{verbatim}
2759 SetScrollbar(wxVERTICAL, 0, 16, 50);
2760 \end{verbatim}
2761 }
2762
2763 Note that with the window at this size, the thumb position can never go
2764 above 50 minus 16, or 34.
2765
2766 You can determine how many lines are currently visible by dividing the current view
2767 size by the character height in pixels.
2768
2769 When defining your own scrollbar behaviour, you will always need to recalculate
2770 the scrollbar settings when the window size changes. You could therefore put your
2771 scrollbar calculations and SetScrollbar
2772 call into a function named AdjustScrollbars, which can be called initially and also
2773 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2798
2799 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2800 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2801 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2802 value has to be adjusted when the window is resized, since the page size will have changed.
2803
2804 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2805 the thumb changes size to reflect the page size relative to the length of the document. When the
2806 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2807 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2808 disappear.
2809
2810 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2811 handling of pages and ranges.

2866
2867 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2868 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2869 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2870 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2871 and usually the scrollbar will be automatically hidden.

2999 If an existing layout constraints object is already owned by the

3002 Note that this function will also call

3052 This function tells a window if it should use the system's "theme" code
3053 to draw the windows' background instead if its own background drawing
3054 code. This does not always have any effect since the underlying platform
3055 obviously needs to support the notion of themes in user defined windows.
3056 One such platform is GTK+ where windows can have (very colourful) backgrounds
3057 defined by a user's selected theme.

3271
3272 \func{virtual void}{Update}{\void}
3273
3274 Calling this method immediately repaints the invalidated area of the window
3275 while this would usually only happen when the flow of control returns to the
3276 event loop. Notice that this function doesn't refresh the window and does
3277 nothing if the window hadn't been already repainted. Use
3278 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
3279 window unconditionally.

3282 \membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
3283
3284 \func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE\_UI\_NONE}}
3285
3286 This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
3287 the window. The particular implementation depends on the window; for
3288 example a wxToolBar will send an update UI event for each toolbar button,
3289 and a wxFrame will send an update UI event for each menubar menu item.
3290 You can call this function from your application to ensure that your
3291 UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
3292 are concerned). This may be necessary if you have called
3293 \helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
3294 \helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
3295 limit the overhead that wxWidgets incurs by sending update UI events in idle time.
3296
3297 {\it flags} should be a bitlist of one or more of the following values.
3298
3299 \begin{verbatim}
3300 enum wxUpdateUI
3301 {
3302 wxUPDATE_UI_NONE = 0x0000, // No particular value
3303 wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
3304 wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
3305 };
3306 \end{verbatim}
3307
3308 If you are calling this function from an OnInternalIdle or OnIdle
3309 function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
3310 this tells the window to only update the UI elements that need
3311 to be updated in idle time. Some windows update their elements
3312 only when necessary, for example when a menu is about to be shown.
3313 The following is an example of how to call UpdateWindowUI from
3314 an idle function.
3315
3316 \begin{verbatim}
3317 void MyWindow::OnInternalIdle()
3318 {
3319 if (wxUpdateUIEvent::CanUpdate(this))
3320 UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
3321 }

3332
3333 \func{virtual bool}{Validate}{\void}
3334
3335 Validates the current values of the child controls using their validators.
3336
3337 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
3338 the method will also call Validate() of all child windows.
3339
3340 \wxheading{Return value}
3341
3342 Returns {\tt false} if any of the validations failed.
