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.}

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

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.

159 The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer.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.

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

950
951 This member function is called in response to a keypress. To intercept this event,
952 use the EVT\_CHAR macro in an event table definition. Your {\bf OnChar} handler may call this
953 default function to achieve default keypress functionality.
954
955 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
956 values.
957
958 Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
959 keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
960 \helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.

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

1034
1035 {\bf Note:} This is an obsolete function.

1055
1056 This is an event handler function called when the user has tried to close a a frame
1057 or dialog box using the window manager (X) or system menu (Windows). It is
1058 called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1059 that the application can also invoke the handler programmatically.
1060
1061 Use the EVT\_CLOSE event table macro to handle close events.
1062
1063 You should check whether the application is forcing the deletion of the window
1064 using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1065 destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1066 If not, it is up to you whether you respond by destroying the window.
1067
1068 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1069 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1070 it is not possible to skip window deletion.)
1071
1072 If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1073 let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1074 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1075
1076 \wxheading{Remarks}
1077
1078 The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1079 for backward compatibility with earlier versions of wxWindows. The
1080 default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1081 destroying the window if it returns TRUE or if the close is being forced.

1129 This event is only generated under Windows. It is therefore recommended that
1130 you set the text background colour explicitly in order to prevent flicker.
1131 The default background colour under GTK is grey.
1132
1133 To intercept this event, use the EVT\_ERASE\_BACKGROUND macro in an event table definition.

1355
1356 \wxheading{Parameters}
1357
1358 \docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1359
1360 \wxheading{Remarks}
1361
1362 Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1363
1364 In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1365
1366 For example:
1367
1368 \small{%
1369 \begin{verbatim}
1370 void MyWindow::OnPaint(wxPaintEvent& event)
1371 {
1372 wxPaintDC dc(this);
1373
1374 DrawMyDocument(dc);
1375 }
1376 \end{verbatim}
1377 }%
1378
1379 You can optimize painting by retrieving the rectangles
1380 that have been damaged and only repainting these. The rectangles are in
1381 terms of the client area, and are unscrolled, so you will need to do
1382 some calculations using the current view position to obtain logical,
1383 scrolled units.
1384
1385 Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1386
1387 {\small%
1388 \begin{verbatim}
1389 // Called when window needs to be repainted.
1390 void MyWindow::OnPaint(wxPaintEvent& event)
1391 {
1392 wxPaintDC dc(this);
1393
1394 // Find Out where the window is scrolled to
1395 int vbX,vbY; // Top left corner of client
1396 ViewStart(&vbX,&vbY);
1397
1398 int vX,vY,vW,vH; // Dimensions of client area in pixels
1399 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1400
1401 while (upd)
1402 {
1403 vX = upd.GetX();
1404 vY = upd.GetY();
1405 vW = upd.GetW();
1406 vH = upd.GetH();
1407
1408 // Alternatively we can do this:
1409 // wxRect rect;
1410 // upd.GetRect(&rect);
1411
1412 // Repaint this rectangle
1413 ...some code...
1414
1415 upd ++ ;
1416 }
1417 }

1578
1579 An event handler is an object that is capable of processing the events
1580 sent to a window. By default, the window is its own event handler, but
1581 an application may wish to substitute another, for example to allow
1582 central implementation of event-handling for a variety of different
1583 window classes.
1584
1585 \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1586 an application to set up a chain of event handlers, where an event not handled by one event handler is
1587 handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1741
1742 \docparam{colour}{The colour to be used as the background colour.}
1743
1744 \wxheading{Remarks}
1745
1746 The background colour is usually painted by the default\rtfsp

1748 under Windows and automatically under GTK.
1749
1750 Note that setting the background colour does not cause an immediate refresh, so you

1773 This sets the size of the window client area in pixels. Using this function to size a window
1774 tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1775 worry about what dimensions the border or title bar have when trying to fit the window

1799 not set it for its children so you'll need to explicitly call SetCursor() for
1800 them too if you need it.

1816 \wxheading{Parameters}
1817
1818 \docparam{handler}{Specifies the handler to be set.}
1819
1820 \wxheading{Remarks}
1821
1822 An event handler is an object that is capable of processing the events
1823 sent to a window. By default, the window is its own event handler, but
1824 an application may wish to substitute another, for example to allow
1825 central implementation of event-handling for a variety of different
1826 window classes.
1827
1828 It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1829 this sets up a chain of event handlers, where an event not handled by one event handler is
1830 handed to the next one in the chain.

1843
1844 Sets the window to have the given layout constraints. The window
1845 will then own the object, and will take care of its deletion.
1846 If an existing layout constraints object is already owned by the
1847 window, it will be deleted.

1851 \docparam{constraints}{The constraints to set. Pass NULL to disassociate and delete the window's
1852 constraints.}
1853
1854 \wxheading{Remarks}
1855
1856 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
1857 the constraints automatically in OnSize; otherwise, you must override OnSize and call Layout()
1858 explicitly. When setting both a wxLayoutConstraints and a \helpref{wxSizer}{wxsizer}, only the
1859 sizer will have effect.

1979 Let's say you wish to display 50 lines of text, using the same font.
1980 The window is sized so that you can only see 16 lines at a time.
1981
1982 You would use:
1983
1984 {\small%
1985 \begin{verbatim}
1986 SetScrollbar(wxVERTICAL, 0, 16, 50);
1987 \end{verbatim}
1988 }
1989
1990 Note that with the window at this size, the thumb position can never go
1991 above 50 minus 16, or 34.
1992
1993 You can determine how many lines are currently visible by dividing the current view
1994 size by the character height in pixels.
1995
1996 When defining your own scrollbar behaviour, you will always need to recalculate
1997 the scrollbar settings when the window size changes. You could therefore put your
1998 scrollbar calculations and SetScrollbar
1999 call into a function named AdjustScrollbars, which can be called initially and also
2000 from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

2021
2022 \wxheading{Remarks}
2023
2024 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2025 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2026 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2027 value has to be adjusted when the window is resized, since the page size will have changed.
2028
2029 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2030 the thumb changes size to reflect the page size relative to the length of the document. When the
2031 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2032 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2033 disappear.
2034
2035 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2036 handling of pages and ranges.

2088
2089 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2090 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2091 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2092 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2093 and usually the scrollbar will be automatically hidden.

2176 \param{int}{ incW=-1}, \param{int}{ incH=-1}}
2177
2178 Allows specification of minimum and maximum window sizes, and window size increments.
2179 If a pair of values is not set (or set to -1), the default values will be used.
2180
2181 \wxheading{Parameters}
2182
2183 \docparam{minW}{Specifies the minimum width allowable.}
2184
2185 \docparam{minH}{Specifies the minimum height allowable.}
2186
2187 \docparam{maxW}{Specifies the maximum width allowable.}
2188
2189 \docparam{maxH}{Specifies the maximum height allowable.}
2190
2191 \docparam{incW}{Specifies the increment for sizing the width (Motif/Xt only).}
2192
2193 \docparam{incH}{Specifies the increment for sizing the height (Motif/Xt only).}
2194
2195 \wxheading{Remarks}
2196
2197 If this function is called, the user will not be able to size the window outside the
2198 given bounds.
2199
2200 The resizing increments are only significant under Motif or Xt.

2202 \membersection{wxWindow::SetSizer}\label{wxwindowsetsizer}
2203
2204 \func{void}{SetSizer}{\param{wxSizer* }{sizer}}
2205
2206 Sets the window to have the given layout sizer. The window
2207 will then own the object, and will take care of its deletion.
2208 If an existing layout constraints object is already owned by the
2209 window, it will be deleted.
2210
2211 \wxheading{Parameters}
2212
2213 \docparam{sizer}{The sizer to set. Pass NULL to disassociate and delete the window's
2214 sizer.}
2215
2216 \wxheading{Remarks}
2217
2218 You must call \helpref{wxWindow::SetAutoLayout}{wxwindowsetautolayout} to tell a window to use
2219 the sizer automatically in OnSize; otherwise, you must override OnSize and call Layout()
2220 explicitly. When setting both a wxSizer and a \helpref{wxLayoutConstraints}{wxlayoutconstraints},
2221 only the sizer will have effect.
