2
3 wxWindow is the base class for all windows. Any children of the window will be deleted
4 automatically by the destructor before the window itself is deleted.
5
6 %Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7 %help text. These must not be called by a user program and are documented only for illustration.
8 %On several platforms, only a few of these handlers are actually written (they are not always
9 %needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10 %the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
11 %platform can implement its native behaviour or just ignore the event if nothing needs to be
12 %done.

25 The following styles can apply to all windows, although they will not always make sense for a particular
26 window class or on all platforms.

30 \twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
31 for this style. }

37 events. Windows only.}
38 \twocolitem{\windowstyle{wxNO\_3D}}{Prevents the children of this window taking on 3D styles, even though
39 the application-wide policy is for 3D controls. Windows only.}
40 \twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
41 \twocolitem{\windowstyle{wxWANTS\_CHARS}}{Use this to indicate that the window
42 wants to get all char events - even for keys like TAB or ENTER which are
43 usually used for dialog navigation and which wouldn't be generated without
44 this style}
45 \twocolitem{\windowstyle{wxNO\_FULL\_REPAINT\_ON\_RESIZE}}{Disables repainting
46 the window completely when its size is changed - you will have to repaint the
47 new window area manually if you use this style. Currently only has an effect for
48 Windows.}

50 \twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
51 \twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being

69 \func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
70 \param{const wxPoint\& }{pos = wxDefaultPosition},
71 \param{const wxSize\& }{size = wxDefaultSize},
72 \param{long }{style = 0},
73 \param{const wxString\& }{name = wxPanelNameStr}}
74
75 Constructs a window, which can be a child of a frame, dialog or any other non-control window.
76
77 \wxheading{Parameters}
78
79 \docparam{parent}{Pointer to a parent window.}
80
81 \docparam{id}{Window identifier. If -1, will automatically create an identifier.}
82
83 \docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
84 should generate a default position for the window. If using the wxWindow class directly, supply
85 an actual position.}
86
87 \docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
88 should generate a default size for the window. If no suitable size can be found, the
89 window will be sized to 20x20 pixels so that the window is visible but obviously not
90 correctly sized. }
91
92 \docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
93
94 \docparam{name}{Window name.}
95
96 \membersection{wxWindow::\destruct{wxWindow}}
97
98 \func{}{\destruct{wxWindow}}{\void}
99
100 Destructor. Deletes all subwindows, then deletes itself. Instead of using
101 the {\bf delete} operator explicitly, you should normally
102 use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
103 can delete a window only when it is safe to do so, in idle time.

111 \membersection{wxWindow::AddChild}
112
113 \func{virtual void}{AddChild}{\param{wxWindow* }{child}}
114
115 Adds a child window. This is called automatically by window creation
116 functions so should not be required by the application programmer.
117
118 \wxheading{Parameters}
119
120 \docparam{child}{Child window to add.}
121
122 \membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
123
124 \func{virtual void}{CaptureMouse}{\void}
125
126 Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
127 release the capture.
128
129 Note that wxWindows maintains the stack of windows having captured the mouse
130 and when the mouse is released the capture returns to the window which had had
131 captured it previously and it is only really released if there were no previous
132 window. In particular, this means that you must release the mouse as many times
133 as you capture it.

156
157 \membersection{wxWindow::Centre}\label{wxwindowcentre}
158
159 \func{void}{Centre}{\param{int}{ direction = wxBOTH}}
160
161 Centres the window.
162
163 \wxheading{Parameters}
164
165 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
166 or {\tt wxBOTH}. It may also include {\tt wxCENTRE\_ON\_SCREEN} flag
167 if you want to center the window on the entire screen and not on its
168 parent window.}
169
170 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer
171 (it has no effect).
172
173 \wxheading{Remarks}
174
175 If the window is a top level one (i.e. doesn't have a parent), it will be
176 centered relative to the screen anyhow.

184 \func{void}{CentreOnParent}{\param{int}{ direction = wxBOTH}}
185
186 Centres the window on its parent. This is a more readable synonym for
187 \helpref{Centre}{wxwindowcentre}.
188
189 \wxheading{Parameters}
190
191 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
192 or {\tt wxBOTH}.}
193
194 \wxheading{Remarks}
195
196 This methods provides for a way to center top level windows over their
197 parents instead of the entire screen. If there is no parent or if the
198 window is not a top level window, then behaviour is the same as
199 \helpref{wxWindow::Centre}{wxwindowcentre}.

207 \func{void}{CentreOnScreen}{\param{int}{ direction = wxBOTH}}
208
209 Centres the window on screen. This only works for top level windows -
210 otherwise, the window will still be centered on its parent.
211
212 \wxheading{Parameters}
213
214 \docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp

233 modifying its parameters.}
234
235 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
236
237 Converts to screen coordinates from coordinates relative to this window.
238
239 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
240 a screen coordinate will be passed out.}
241
242 \docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
243 a screen coordinate will be passed out.}
244
245 \docparam{pt}{The client position for the second form of the function.}
246
247 \pythonnote{In place of a single overloaded method name, wxPython
248 implements the following methods:\par

254
255 \membersection{wxWindow::Close}\label{wxwindowclose}
256
257 \func{bool}{Close}{\param{bool}{ force = {\tt false}}}
258
259 This function simply generates a \helpref{wxCloseEvent}{wxcloseevent} whose
260 handler usually tries to close the window. It doesn't close the window itself,
261 however.
262
263 \wxheading{Parameters}
264
265 \docparam{force}{{\tt false} if the window's close handler should be able to veto the destruction
266 of this window, {\tt true} if it cannot.}
267
268 \wxheading{Remarks}
269
270 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing
271 an opportunity for the window to choose whether to destroy the window.
272 Usually it is only used with the top level windows (wxFrame and wxDialog
273 classes) as the others are not supposed to have any special OnClose() logic.
274
275 The close handler should check whether the window is being deleted forcibly,
276 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it
277 should destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
278
279 {\it Note} that calling Close does not guarantee that the window will be
280 destroyed; but it provides a way to simulate a manual close of a window, which
281 may or may not be implemented by destroying the window. The default
282 implementation of wxDialog::OnCloseWindow does not necessarily delete the
283 dialog, since it will simply simulate an wxID\_CANCEL event which is handled by
284 the appropriate button event handler and may do anything at all.
285
286 To guarantee that the window will be destroyed, call
287 \helpref{wxWindow::Destroy}{wxwindowdestroy} instead

296
297 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
298
299 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
300
301 Converts a point or size from dialog units to pixels.
302
303 For the x dimension, the dialog units are multiplied by the average character width
304 and then divided by 4.
305
306 For the y dimension, the dialog units are multiplied by the average character height
307 and then divided by 8.
308
309 \wxheading{Remarks}
310
311 Dialog units are used for maintaining a dialog's proportions even if the font changes.
312 Dialogs created using Dialog Editor optionally use dialog units.
313
314 You can also use these functions programmatically. A convenience macro is defined:
315
316 {\small
317 \begin{verbatim}
318 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

378
379 Destroys the window safely. Use this function instead of the delete operator, since
380 different window classes can be destroyed differently. Frames and dialogs
381 are not destroyed immediately when this function is called -- they are added
382 to a list of windows to be deleted on idle time, when all the window's events
383 have been processed. This prevents problems with events being sent to non-existent
384 windows.
385
386 \wxheading{Return value}

521
522 \func{virtual void}{Fit}{\void}
523
524 Sizes the window so that it fits around its subwindows. This function won't do
525 anything if there are no subwindows.
526
527 \membersection{wxWindow::FitInside}\label{wxwindowfitinside}

529 \func{virtual void}{FitInside}{\void}
530
531 Similar to \helpref{Fit}{wxwindowfit}, but sizes the interior (virtual) size
532 of a window. Mainly useful with scrolled windows to reset scrollbars after
533 sizing changes that do not trigger a size event, and/or scrolled windows without
534 an interior sizer. This function similarly won't do anything if there are no
535 subwindows.
536
537 \membersection{wxWindow::Freeze}\label{wxwindowfreeze}
538
539 \func{virtual void}{Freeze}{\void}
540
541 Freezes the window or, in other words, prevents any updates from taking place
542 on screen, the window is not redrawn at all. \helpref{Thaw}{wxwindowthaw} must
543 be called to reenable window redrawing.
544
545 This method is useful for visual appearance optimization (for example, it
546 is a good idea to use it before inserting large amount of text into a
547 wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
548 controls so it is mostly just a hint to wxWindows and not a mandatory

1975 Determines whether the \helpref{wxWindow::Layout}{wxwindowlayout} function will
1976 be called automatically when the window is resized. It is called implicitly by
1977 \helpref{wxWindow::SetSizer}{wxwindowsetsizer} but if you use
1978 \helpref{wxWindow::SetConstraints}{wxwindowsetconstraints} you should call it
1979 manually or otherwise the window layout won't be correctly updated when its

1998
1999 \docparam{colour}{The colour to be used as the background colour.}
2000
2001 \wxheading{Remarks}
2002
2003 The background colour is usually painted by the default\rtfsp
2004 \helpref{wxEraseEvent}{wxeraseevent} event handler function
2005 under Windows and automatically under GTK.
2006
2007 Note that setting the background colour does not cause an immediate refresh, so you
2008 may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
2009 calling this function.
2010
2011 Use this function with care under GTK as the new appearance of the window might
2012 not look equally well when used with "Themes", i.e GTK's ability to change its
2013 look as the user wishes with run-time loadable modules.

2034 \func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
2035
2036 This sets the size of the window client area in pixels. Using this function to size a window
2037 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
2038 worry about what dimensions the border or title bar have when trying to fit the window
2039 around panel items, for example.

2089 Sets the window to have the given layout constraints. The window
2090 will then own the object, and will take care of its deletion.
2091 If an existing layout constraints object is already owned by the
2092 window, it will be deleted.
2093
2094 \wxheading{Parameters}

2096 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
2097 constraints.}
2098
2099 \wxheading{Remarks}
2100
2101 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2102 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
2103 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the

2167 \twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a

2312 Let's say you wish to display 50 lines of text, using the same font.
2313 The window is sized so that you can only see 16 lines at a time.
2314
2315 You would use:
2316
2317 {\small%
2318 \begin{verbatim}
2319 SetScrollbar(wxVERTICAL, 0, 16, 50);
2320 \end{verbatim}
2321 }
2322
2323 Note that with the window at this size, the thumb position can never go
2324 above 50 minus 16, or 34.
2325
2326 You can determine how many lines are currently visible by dividing the current view
2327 size by the character height in pixels.
2328
2329 When defining your own scrollbar behaviour, you will always need to recalculate
2330 the scrollbar settings when the window size changes. You could therefore put your
2331 scrollbar calculations and SetScrollbar
2332 call into a function named AdjustScrollbars, which can be called initially and also
2333 from your \helpref{wxSizeEvent}{wxsizeevent} handler function.

2354
2355 \wxheading{Remarks}
2356
2357 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2358 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2359 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2360 value has to be adjusted when the window is resized, since the page size will have changed.
2361
2362 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2363 the thumb changes size to reflect the page size relative to the length of the document. When the
2364 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2365 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2366 disappear.
2367
2368 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2369 handling of pages and ranges.

2421
2422 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2423 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2424 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2425 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2426 and usually the scrollbar will be automatically hidden.

2656 \membersection{wxWindow::SetWindowStyleFlag}\label{wxwindowsetwindowstyleflag}
2657
2658 \func{virtual void}{SetWindowStyleFlag}{\param{long}{ style}}
2659
2660 Sets the style of the window. Please note that some styles cannot be changed
2661 after the window creation and that \helpref{Refresh()}{wxwindowrefresh} might
2662 be called after changing the others for the change to take place immediately.
2663
2664 See \helpref{Window styles}{windowstyles} for more information about flags.

2670 \membersection{wxWindow::Show}\label{wxwindowshow}
2671
2672 \func{virtual bool}{Show}{\param{bool}{ show = {\tt true}}}
2673
2674 Shows or hides the window. You may need to call \helpref{Raise}{wxwindowraise}
2675 for a top level window if you want to bring it to top, although this is not
2676 needed if Show() is called immediately after the frame creation.
2677
2678 \wxheading{Parameters}
2679
2680 \docparam{show}{If {\tt true} displays the window. Otherwise, hides it.}
2681
2682 \wxheading{Return value}
2683
2684 {\tt true} if the window has been shown or hidden or {\tt false} if nothing was
2685 done because it already was in the requested state.

2698 \membersection{wxWindow::TransferDataFromWindow}\label{wxwindowtransferdatafromwindow}
2699
2700 \func{virtual bool}{TransferDataFromWindow}{\void}
2701
2702 Transfers values from child controls to data areas specified by their validators. Returns
2703 {\tt false} if a transfer failed.
2704
2705 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2706 the method will also call TransferDataFromWindow() of all child windows.

2734
2735 Calling this method immediately repaints the invalidated area of the window
2736 while this would usually only happen when the flow of control returns to the
2737 event loop. Notice that this function doesn't refresh the window and does
2738 nothing if the window hadn't been already repainted. Use
2739 \helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
2740 window unconditionally.
2741
2742 \membersection{wxWindow::Validate}\label{wxwindowvalidate}
2743
2744 \func{virtual bool}{Validate}{\void}
2745
2746 Validates the current values of the child controls using their validators.
2747
2748 If the window has {\tt wxWS\_EX\_VALIDATE\_RECURSIVELY} extra style flag set,
2749 the method will also call Validate() of all child windows.
2750
2751 \wxheading{Return value}
2752
2753 Returns {\tt false} if any of the validations failed.
