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.

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.}

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

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.

158
159 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer.
160
161 \wxheading{Remarks}
162
163 If the window is a top level one (i.e. doesn't have a parent), it will be
164 centered relative to the screen anyhow.

183 This methods provides for a way to center top level windows over their
184 parents instead of the entire screen. If there is no parent or if the
185 window is not a top level window, then behaviour is the same as
186 \helpref{wxWindow::Centre}{wxwindowcentre}.

199 \membersection{wxWindow::ClientToScreen}
200
201 \constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
202
203 \constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
204
205 Converts to screen coordinates from coordinates relative to this window.
206
207 \docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
208 a screen coordinate will be passed out.}

222
223
224 \membersection{wxWindow::Close}\label{wxwindowclose}
225
226 \func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
227
228 The purpose of this call is to provide a safer way of destroying a window than using
229 the {\it delete} operator.
230
231 \wxheading{Parameters}
232
233 \docparam{force}{FALSE if the window's close handler should be able to veto the destruction
234 of this window, TRUE if it cannot.}
235
236 \wxheading{Remarks}
237
238 Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
239 choose whether to destroy the window.
240
241 The close handler should check whether the window is being deleted forcibly,
242 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
243 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
244
245 Applies to managed windows (wxFrame and wxDialog classes) only.
246
247 {\it Note} that calling Close does not guarantee that the window will be destroyed; but it
248 provides a way to simulate a manual close of a window, which may or may not be implemented by
249 destroying the window. The default implementation of wxDialog::OnCloseWindow does not
250 necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
251 itself only hides the dialog.
252
253 To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

263
264 \func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
265
266 \func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
267
268 Converts a point or size from dialog units to pixels.
269
270 For the x dimension, the dialog units are multiplied by the average character width
271 and then divided by 4.
272
273 For the y dimension, the dialog units are multiplied by the average character height
274 and then divided by 8.
275
276 \wxheading{Remarks}
277
278 Dialog units are used for maintaining a dialog's proportions even if the font changes.
279 Dialogs created using Dialog Editor optionally use dialog units.
280
281 You can also use these functions programmatically. A convenience macro is defined:
282
283 {\small
284 \begin{verbatim}
285 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
286 \end{verbatim}

346 Destroys the window safely. Use this function instead of the delete operator, since
347 different window classes can be destroyed differently. Frames and dialogs
348 are not destroyed immediately when this function is called - they are added
349 to a list of windows to be deleted on idle time, when all the window's events
350 have been processed. This prevents problems with events being sent to non-existant
351 windows.
352

948
949 This member function is called in response to a keypress. To intercept this event,

952
953 Note that the ASCII values do not have explicit key codes: they are passed as ASCII

955
956 Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
957 keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
958 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.

973 before they are processed by child windows.
974
975 \wxheading{Parameters}
976
977 \docparam{event}{Object containing keypress information. See \helpref{wxKeyEvent}{wxkeyevent} for
978 details about this class.}
979
980 \wxheading{Remarks}
981
982 This member function is called in response to a keypress, if the window is active. To intercept this event,
983 use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
984 keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
985
986 An example of using this function is in the implementation of escape-character processing for wxDialog,
987 where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
988
989 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
990 values.
991
992 This function is only relevant to top-level windows (frames and dialogs), and under
993 Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
994 you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
995 the window won't get the event.

1053
1054 This is an event handler function called when the user has tried to close a a frame
1055 or dialog box using the window manager (X) or system menu (Windows). It is
1056 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1057 that the application can also invoke the handler programmatically.
1058
1059 Use the EVT\_CLOSE event table macro to handle close events.
1060
1061 You should check whether the application is forcing the deletion of the window
1062 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1063 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1064 If not, it is up to you whether you respond by destroying the window.
1065
1066 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1067 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1068 it is not possible to skip window deletion.)
1069
1070 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1071 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1072 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1073
1074 \wxheading{Remarks}
1075
1076 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1077 for backward compatibility with earlier versions of wxWindows. The
1078 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1079 destroying the window if it returns TRUE or if the close is being forced.

1127 This event is only generated under Windows. It is therefore recommended that
1128 you set the text background colour explicitly in order to prevent flicker.
1129 The default background colour under GTK is grey.

1353
1354 \wxheading{Parameters}
1355
1356 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1357
1358 \wxheading{Remarks}
1359
1360 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1361
1362 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1363
1364 For example:
1365
1366 \small{%
1367 \begin{verbatim}
1368 void MyWindow::OnPaint(wxPaintEvent& event)
1369 {
1370 wxPaintDC dc(this);
1371
1372 DrawMyDocument(dc);
1373 }
1374 \end{verbatim}
1375 }%
1376
1377 You can optimize painting by retrieving the rectangles
1378 that have been damaged and only repainting these. The rectangles are in
1379 terms of the client area, and are unscrolled, so you will need to do
1380 some calculations using the current view position to obtain logical,
1381 scrolled units.
1382
1383 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1384
1385 {\small%
1386 \begin{verbatim}
1387 // Called when window needs to be repainted.
1388 void MyWindow::OnPaint(wxPaintEvent& event)
1389 {
1390 wxPaintDC dc(this);
1391
1392 // Find Out where the window is scrolled to
1393 int vbX,vbY; // Top left corner of client
1394 ViewStart(&vbX,&vbY);
1395
1396 int vX,vY,vW,vH; // Dimensions of client area in pixels
1397 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1398
1399 while (upd)
1400 {
1401 vX = upd.GetX();
1402 vY = upd.GetY();
1403 vW = upd.GetW();
1404 vH = upd.GetH();
1405
1406 // Alternatively we can do this:
1407 // wxRect rect;
1408 // upd.GetRect(&rect);
1409
1410 // Repaint this rectangle
1411 ...some code...
1412
1413 upd ++ ;
1414 }
1415 }

1576
1577 An event handler is an object that is capable of processing the events
1578 sent to a window. By default, the window is its own event handler, but
1579 an application may wish to substitute another, for example to allow
1580 central implementation of event-handling for a variety of different
1581 window classes.
1582
1583 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1584 an application to set up a chain of event handlers, where an event not handled by one event handler is
1585 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1739
1740 \docparam{colour}{The colour to be used as the background colour.}
1741
1742 \wxheading{Remarks}
1743
1744 The background colour is usually painted by the default\rtfsp

1746 under Windows and automatically under GTK.
1747
1748 Note that setting the background colour does not cause an immediate refresh, so you

1771 This sets the size of the window client area in pixels. Using this function to size a window
1772 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1773 worry about what dimensions the border or title bar have when trying to fit the window

1797 not set it for its children so you'll need to explicitly call SetCursor() for
1798 them too if you need it.

1814 \wxheading{Parameters}
1815
1816 \docparam{handler}{Specifies the handler to be set.}
1817
1818 \wxheading{Remarks}
1819
1820 An event handler is an object that is capable of processing the events
1821 sent to a window. By default, the window is its own event handler, but
1822 an application may wish to substitute another, for example to allow
1823 central implementation of event-handling for a variety of different
1824 window classes.
1825
1826 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1827 this sets up a chain of event handlers, where an event not handled by one event handler is
1828 handed to the next one in the chain.

1841
1842 Sets the window to have the given layout constraints. The window
1843 will then own the object, and will take care of its deletion.
1844 If an existing layout constraints object is already owned by the
1845 window, it will be deleted.

1849 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
1850 constraints.}
1851
1852 \wxheading{Remarks}
1853
1854 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
1855 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
1856 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
1857 sizer will have effect.

1977 Let's say you wish to display 50 lines of text, using the same font.
1978 The window is sized so that you can only see 16 lines at a time.
1979
1980 You would use:
1981
1982 {\small%
1983 \begin{verbatim}
1984 SetScrollbar(wxVERTICAL, 0, 16, 50);
1985 \end{verbatim}
1986 }
1987
1988 Note that with the window at this size, the thumb position can never go
1989 above 50 minus 16, or 34.
1990
1991 You can determine how many lines are currently visible by dividing the current view
1992 size by the character height in pixels.
1993
1994 When defining your own scrollbar behaviour, you will always need to recalculate
1995 the scrollbar settings when the window size changes. You could therefore put your
1996 scrollbar calculations and SetScrollbar
1997 call into a function named AdjustScrollbars, which can be called initially and also
1998 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

2020 \wxheading{Remarks}
2021
2022 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2023 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2024 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2025 value has to be adjusted when the window is resized, since the page size will have changed.
2026
2027 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2028 the thumb changes size to reflect the page size relative to the length of the document. When the
2029 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2030 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2031 disappear.
2032
2033 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2034 handling of pages and ranges.

2086
2087 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2088 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2089 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2090 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2091 and usually the scrollbar will be automatically hidden.

2174 \param{int}{ incW=-1}, \param{int}{ incH=-1}}
2175
2176 Allows specification of minimum and maximum window sizes, and window size increments.
2177 If a pair of values is not set (or set to -1), the default values will be used.
2178
2179 \wxheading{Parameters}
2180
2181 \docparam{minW}{Specifies the minimum width allowable.}
2182
2183 \docparam{minH}{Specifies the minimum height allowable.}
2184
2185 \docparam{maxW}{Specifies the maximum width allowable.}
2186
2187 \docparam{maxH}{Specifies the maximum height allowable.}
2188
2189 \docparam{incW}{Specifies the increment for sizing the width (Motif/Xt only).}
2190
2191 \docparam{incH}{Specifies the increment for sizing the height (Motif/Xt only).}
2192
2193 \wxheading{Remarks}
2194
2195 If this function is called, the user will not be able to size the window outside the
2196 given bounds.
2197
2198 The resizing increments are only significant under Motif or Xt.

2200 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
2201
2202 \func{void}{SetSizer}{\param{wxSizer* }{sizer}}
2203
2204 Sets the window to have the given layout sizer. The window
2205 will then own the object, and will take care of its deletion.
2206 If an existing layout constraints object is already owned by the
2207 window, it will be deleted.
2208
2209 \wxheading{Parameters}
2210
2211 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and delete the window's
2212 sizer.}
2213
2214 \wxheading{Remarks}
2215
2216 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2217 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2218 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2219 only the sizer will have effect.
