3wxWindow is the base class for all windows. Any
4children of the window will be deleted automatically by the destructor
5before the window itself is deleted.

51
52Default constructor.
53
54\func{}{wxWindow}{\param{wxWindow*}{ parent}, \param{wxWindowID }{id},
55 \param{const wxPoint\& }{pos = wxDefaultPosition},
56 \param{const wxSize\& }{size = wxDefaultSize},
57 \param{long }{style = 0},
58 \param{const wxString\& }{name = wxPanelNameStr}}
59
60Constructs a window, which can be a child of a frame, dialog or any other non-control window.
61
62\wxheading{Parameters}
63
64\docparam{parent}{Pointer to a parent window.}
65
66\docparam{id}{Window identifier. If -1, will automatically create an identifier.}
67
68\docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
69should generate a default position for the window. If using the wxWindow class directly, supply
70an actual position.}
71
72\docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
73should generate a default size for the window. If no suitable size can be found, the
74window will be sized to 20x20 pixels so that the window is visible but obviously not
75correctly sized. }
76
77\docparam{style}{Window style. For generic window styles, please see \helpref{wxWindow}{wxwindow}.}
78
79\docparam{name}{Window name.}
80
81\membersection{wxWindow::\destruct{wxWindow}}
82
83\func{}{\destruct{wxWindow}}{\void}
84
85Destructor. Deletes all subwindows, then deletes itself. Instead of using
86the {\bf delete} operator explicitly, you should normally
87use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
88can delete a window only when it is safe to do so, in idle time.

142
143The flag {\tt wxCENTRE\_FRAME} is obsolete and should not be used any longer.
144
145\wxheading{Remarks}
146
147If the window is a top level one (i.e. doesn't have a parent), it will be
148centered relative to the screen anyhow.

166
167This methods provides for a way to center top level windows over their
168parents instead of the entire screen. If there is no parent or if the
169window is not a top level window, then behaviour is the same as
170\helpref{wxWindow::Centre}{wxwindowcentre}.

185\constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
186
187\constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
188
189Converts to screen coordinates from coordinates relative to this window.
190
191\docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
192a screen coordinate will be passed out.}

207
208\membersection{wxWindow::Close}\label{wxwindowclose}
209
210\func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
211
212The purpose of this call is to provide a safer way of destroying a window than using
213the {\it delete} operator.
214
215\wxheading{Parameters}
216
217\docparam{force}{FALSE if the window's close handler should be able to veto the destruction
218of this window, TRUE if it cannot.}
219
220\wxheading{Remarks}
221
222Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
223choose whether to destroy the window.
224
225The close handler should check whether the window is being deleted forcibly,
226using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
227destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
228
229Applies to managed windows (wxFrame and wxDialog classes) only.
230
231{\it Note} that calling Close does not guarantee that the window will be destroyed; but it
232provides a way to simulate a manual close of a window, which may or may not be implemented by
233destroying the window. The default implementation of wxDialog::OnCloseWindow does not
234necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
235itself only hides the dialog.
236
237To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

247
248\func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
249
250\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
251
252Converts a point or size from dialog units to pixels.
253
254For the x dimension, the dialog units are multiplied by the average character width
255and then divided by 4.
256
257For the y dimension, the dialog units are multiplied by the average character height
258and then divided by 8.
259
260\wxheading{Remarks}
261
262Dialog units are used for maintaining a dialog's proportions even if the font changes.
263Dialogs created using Dialog Editor optionally use dialog units.
264
265You can also use these functions programmatically. A convenience macro is defined:
266
267{\small
268\begin{verbatim}
269#define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
270\end{verbatim}

329
330Destroys the window safely. Use this function instead of the delete operator, since
331different window classes can be destroyed differently. Frames and dialogs
332are not destroyed immediately when this function is called - they are added
333to a list of windows to be deleted on idle time, when all the window's events
334have been processed. This prevents problems with events being sent to non-existant
335windows.
336
337\wxheading{Return value}
338
339TRUE if the window has either been successfully deleted, or it has been added
340to the list of windows pending real deletion.

918This member function is called in response to a keypress. To intercept this event,

924
925Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
926keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or

948
949\wxheading{Remarks}
950
951This member function is called in response to a keypress, if the window is active. To intercept this event,
952use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
953keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
954
955An example of using this function is in the implementation of escape-character processing for wxDialog,
956where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
957
958Note that the ASCII values do not have explicit key codes: they are passed as ASCII
959values.
960
961This function is only relevant to top-level windows (frames and dialogs), and under
962Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
963you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
964the window won't get the event.

1001
1002{\bf Note:} This is an obsolete function.

1022
1023This is an event handler function called when the user has tried to close a a frame
1024or dialog box using the window manager (X) or system menu (Windows). It is
1025called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1026that the application can also invoke the handler programmatically.
1027
1028Use the EVT\_CLOSE event table macro to handle close events.
1029
1030You should check whether the application is forcing the deletion of the window
1031using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1032destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1033If not, it is up to you whether you respond by destroying the window.
1034
1035(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1036the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1037it is not possible to skip window deletion.)
1038
1039If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1040let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1041to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1042
1043\wxheading{Remarks}
1044
1045The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1046for backward compatibility with earlier versions of wxWindows. The
1047default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1048destroying the window if it returns TRUE or if the close is being forced.

1149This member function is called in response to a key up event. To intercept this event,
1150use the EVT\_KEY\_UP macro in an event table definition. Your {\bf OnKeyUp} handler may call this
1151default function to achieve default keypress functionality.
1152
1153Note that not all keypresses can be intercepted this way. If you wish to intercept special
1154keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
1155\helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
1156
1157Most, but not all, windows allow key up events to be intercepted.

1244pressed.
1245
1246\wxheading{Parameters}

1321Sent to the event handler when the window must be refreshed.
1322
1323\wxheading{Parameters}
1324
1325\docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1326
1327\wxheading{Remarks}
1328
1329Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1330
1331In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1332
1333For example:
1334
1335\small{%
1336\begin{verbatim}
1337 void MyWindow::OnPaint(wxPaintEvent& event)
1338 {
1339 wxPaintDC dc(this);
1340
1341 DrawMyDocument(dc);
1342 }
1343\end{verbatim}
1344}%
1345
1346You can optimize painting by retrieving the rectangles
1347that have been damaged and only repainting these. The rectangles are in
1348terms of the client area, and are unscrolled, so you will need to do
1349some calculations using the current view position to obtain logical,
1350scrolled units.
1351
1352Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1353
1354{\small%
1355\begin{verbatim}
1356// Called when window needs to be repainted.
1357void MyWindow::OnPaint(wxPaintEvent& event)
1358{
1359 wxPaintDC dc(this);
1360
1361 // Find Out where the window is scrolled to
1362 int vbX,vbY; // Top left corner of client
1363 ViewStart(&vbX,&vbY);
1364
1365 int vX,vY,vW,vH; // Dimensions of client area in pixels
1366 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1367
1368 while (upd)
1369 {
1370 vX = upd.GetX();
1371 vY = upd.GetY();
1372 vW = upd.GetW();
1373 vH = upd.GetH();
1374
1375 // Alternatively we can do this:
1376 // wxRect rect;
1377 // upd.GetRect(&rect);
1378
1379 // Repaint this rectangle
1380 ...some code...
1381
1382 upd ++ ;
1383 }
1384}

1546An event handler is an object that is capable of processing the events
1547sent to a window. By default, the window is its own event handler, but
1548an application may wish to substitute another, for example to allow
1549central implementation of event-handling for a variety of different
1550window classes.
1551
1552\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1553an application to set up a chain of event handlers, where an event not handled by one event handler is
1554handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1703
1704\docparam{colour}{The colour to be used as the background colour.}
1705
1706\wxheading{Remarks}
1707
1708The background colour is usually painted by the default\rtfsp
1709\helpref{wxWindow::OnEraseBackground}{wxwindowonerasebackground} event handler function
1710under Windows and automatically under GTK.
1711
1712Note that setting the background colour does not cause an immediate refresh, so you
1713may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
1714calling this function.
1715

1734
1735This sets the size of the window client area in pixels. Using this function to size a window
1736tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1737worry about what dimensions the border or title bar have when trying to fit the window
1738around panel items, for example.

1779
1780\docparam{handler}{Specifies the handler to be set.}
1781
1782\wxheading{Remarks}
1783
1784An event handler is an object that is capable of processing the events
1785sent to a window. By default, the window is its own event handler, but
1786an application may wish to substitute another, for example to allow
1787central implementation of event-handling for a variety of different
1788window classes.
1789
1790It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1791this sets up a chain of event handlers, where an event not handled by one event handler is
1792handed to the next one in the chain.

1940Let's say you wish to display 50 lines of text, using the same font.
1941The window is sized so that you can only see 16 lines at a time.
1942
1943You would use:
1944
1945{\small%
1946\begin{verbatim}
1947 SetScrollbar(wxVERTICAL, 0, 16, 50);
1948\end{verbatim}
1949}
1950
1951Note that with the window at this size, the thumb position can never go
1952above 50 minus 16, or 34.
1953
1954You can determine how many lines are currently visible by dividing the current view
1955size by the character height in pixels.
1956
1957When defining your own scrollbar behaviour, you will always need to recalculate
1958the scrollbar settings when the window size changes. You could therefore put your
1959scrollbar calculations and SetScrollbar
1960call into a function named AdjustScrollbars, which can be called initially and also
1961from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1976
1977\docparam{orientation}{Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.}

1980
1981\docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.}
1982
1983\wxheading{Remarks}
1984
1985The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1986click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1987page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1988value has to be adjusted when the window is resized, since the page size will have changed.
1989
1990In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1991the thumb changes size to reflect the page size relative to the length of the document. When the
1992document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1993will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1994disappear.
1995
1996Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1997handling of pages and ranges.

2049
2050The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2051object length of the scrollbar. If you are implementing a scrolling window, for example, you
2052would adjust the scroll range when the window is resized, by subtracting the window view size from the
2053total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2054and usually the scrollbar will be automatically hidden.
