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.

97\membersection{wxWindow::AddChild}
98
99\func{virtual void}{AddChild}{\param{wxWindow* }{child}}
100
101Adds a child window. This is called automatically by window creation
102functions so should not be required by the application programmer.
103
104\wxheading{Parameters}
105
106\docparam{child}{Child window to add.}
107
108\membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}

135Centres the window.
136
137\wxheading{Parameters}
138
139\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
140or {\tt wxBOTH}.}
141
142\wxheading{Remarks}
143
144The actual behaviour depends on the derived window. For a frame or dialog box,
145centring is relative to the whole display. For a panel item, centring is
146relative to the panel.

164
165This methods provides for a way to center top level windows over their
166parents instead of the entire screen. If there is no parent or if the
167window is not a top level window, then behaviour is the same as
168\helpref{wxWindow::Centre}{wxwindowcentre}.

183\constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
184
185\constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
186
187Converts to screen coordinates from coordinates relative to this window.
188
189\docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
190a screen coordinate will be passed out.}
191
192\docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
193a screen coordinate will be passed out.}
194
195\docparam{pt}{The client position for the second form of the function.}
196

205
206\membersection{wxWindow::Close}\label{wxwindowclose}
207
208\func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
209
210The purpose of this call is to provide a safer way of destroying a window than using
211the {\it delete} operator.
212
213\wxheading{Parameters}
214
215\docparam{force}{FALSE if the window's close handler should be able to veto the destruction
216of this window, TRUE if it cannot.}
217
218\wxheading{Remarks}
219
220Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
221choose whether to destroy the window.
222
223The close handler should check whether the window is being deleted forcibly,
224using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
225destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
226
227Applies to managed windows (wxFrame and wxDialog classes) only.
228
229{\it Note} that calling Close does not guarantee that the window will be destroyed; but it
230provides a way to simulate a manual close of a window, which may or may not be implemented by
231destroying the window. The default implementation of wxDialog::OnCloseWindow does not
232necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
233itself only hides the dialog.
234
235To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

245
246\func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
247
248\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
249
250Converts a point or size from dialog units to pixels.
251
252For the x dimension, the dialog units are multiplied by the average character width
253and then divided by 4.
254
255For the y dimension, the dialog units are multiplied by the average character height
256and then divided by 8.
257
258\wxheading{Remarks}
259
260Dialog units are used for maintaining a dialog's proportions even if the font changes.
261Dialogs created using Dialog Editor optionally use dialog units.
262
263You can also use these functions programmatically. A convenience macro is defined:
264
265{\small
266\begin{verbatim}
267#define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
268\end{verbatim}

297
298Converts a point or size from pixels to dialog units.
299
300For the x dimension, the pixels are multiplied by 4 and then divided by the average
301character width.
302
303For the y dimension, the pixels are multipled by 8 and then divided by the average
304character height.

325
326\func{virtual bool}{Destroy}{\void}
327
328Destroys the window safely. Use this function instead of the delete operator, since
329different window classes can be destroyed differently. Frames and dialogs
330are not destroyed immediately when this function is called - they are added
331to a list of windows to be deleted on idle time, when all the window's events
332have been processed. This prevents problems with events being sent to non-existant
333windows.
334
335\wxheading{Return value}
336
337TRUE if the window has either been successfully deleted, or it has been added
338to the list of windows pending real deletion.

916This member function is called in response to a keypress. To intercept this event,

922
923Note that not all keypresses can be intercepted this way. If you wish to intercept modifier
924keypresses, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or

946
947\wxheading{Remarks}
948
949This member function is called in response to a keypress, if the window is active. To intercept this event,
950use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
951keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
952
953An example of using this function is in the implementation of escape-character processing for wxDialog,
954where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
955
956Note that the ASCII values do not have explicit key codes: they are passed as ASCII
957values.
958
959This function is only relevant to top-level windows (frames and dialogs), and under
960Windows only. Under GTK the normal EVT\_CHAR\_ event has the functionality, i.e.
961you can intercepts it and if you don't call \helpref{wxEvent::Skip}{wxeventskip}
962the window won't get the event.

1020
1021This is an event handler function called when the user has tried to close a a frame
1022or dialog box using the window manager (X) or system menu (Windows). It is
1023called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1024that the application can also invoke the handler programmatically.
1025
1026Use the EVT\_CLOSE event table macro to handle close events.
1027
1028You should check whether the application is forcing the deletion of the window
1029using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1030destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1031If not, it is up to you whether you respond by destroying the window.
1032
1033(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1034the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1035it is not possible to skip window deletion.)
1036
1037If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1038let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1039to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1040
1041\wxheading{Remarks}
1042
1043The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1044for backward compatibility with earlier versions of wxWindows. The
1045default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1046destroying the window if it returns TRUE or if the close is being forced.

1147This member function is called in response to a key up event. To intercept this event,
1148use the EVT\_KEY\_UP macro in an event table definition. Your {\bf OnKeyUp} handler may call this
1149default function to achieve default keypress functionality.
1150
1151Note that not all keypresses can be intercepted this way. If you wish to intercept special
1152keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
1153\helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
1154
1155Most, but not all, windows allow key up events to be intercepted.

1242pressed.
1243
1244\wxheading{Parameters}

1319Sent to the event handler when the window must be refreshed.
1320
1321\wxheading{Parameters}
1322
1323\docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
1324
1325\wxheading{Remarks}
1326
1327Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1328
1329In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
1330
1331For example:
1332
1333\small{%
1334\begin{verbatim}
1335 void MyWindow::OnPaint(wxPaintEvent& event)
1336 {
1337 wxPaintDC dc(this);
1338
1339 DrawMyDocument(dc);
1340 }
1341\end{verbatim}
1342}%
1343
1344You can optimize painting by retrieving the rectangles
1345that have been damaged and only repainting these. The rectangles are in
1346terms of the client area, and are unscrolled, so you will need to do
1347some calculations using the current view position to obtain logical,
1348scrolled units.
1349
1350Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
1351
1352{\small%
1353\begin{verbatim}
1354// Called when window needs to be repainted.
1355void MyWindow::OnPaint(wxPaintEvent& event)
1356{
1357 wxPaintDC dc(this);
1358
1359 // Find Out where the window is scrolled to
1360 int vbX,vbY; // Top left corner of client
1361 ViewStart(&vbX,&vbY);
1362
1363 int vX,vY,vW,vH; // Dimensions of client area in pixels
1364 wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
1365
1366 while (upd)
1367 {
1368 vX = upd.GetX();
1369 vY = upd.GetY();
1370 vW = upd.GetW();
1371 vH = upd.GetH();
1372
1373 // Alternatively we can do this:
1374 // wxRect rect;
1375 // upd.GetRect(&rect);
1376
1377 // Repaint this rectangle
1378 ...some code...
1379
1380 upd ++ ;
1381 }
1382}

1535An event handler is an object that is capable of processing the events

1537an application may wish to substitute another, for example to allow
1538central implementation of event-handling for a variety of different
1539window classes.
1540
1541\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
1542an application to set up a chain of event handlers, where an event not handled by one event handler is
1543handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to

1679
1680\docparam{colour}{The colour to be used as the background colour.}
1681
1682\wxheading{Remarks}
1683
1684The background colour is usually painted by the default\rtfsp

1686under Windows and automatically under GTK.
1687
1688Note that setting the background colour does not cause an immediate refresh, so you
1689may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
1690calling this function.

1711This sets the size of the window client area in pixels. Using this function to size a window
1712tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
1713worry about what dimensions the border or title bar have when trying to fit the window

1755
1756\docparam{handler}{Specifies the handler to be set.}
1757
1758\wxheading{Remarks}
1759
1760An event handler is an object that is capable of processing the events
1761sent to a window. By default, the window is its own event handler, but
1762an application may wish to substitute another, for example to allow
1763central implementation of event-handling for a variety of different
1764window classes.
1765
1766It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
1767this sets up a chain of event handlers, where an event not handled by one event handler is
1768handed to the next one in the chain.

1915
1916Let's say you wish to display 50 lines of text, using the same font.
1917The window is sized so that you can only see 16 lines at a time.
1918
1919You would use:
1920
1921{\small%
1922\begin{verbatim}
1923 SetScrollbar(wxVERTICAL, 0, 16, 50);
1924\end{verbatim}
1925}
1926
1927Note that with the window at this size, the thumb position can never go
1928above 50 minus 16, or 34.
1929
1930You can determine how many lines are currently visible by dividing the current view
1931size by the character height in pixels.
1932
1933When defining your own scrollbar behaviour, you will always need to recalculate
1934the scrollbar settings when the window size changes. You could therefore put your
1935scrollbar calculations and SetScrollbar
1936call into a function named AdjustScrollbars, which can be called initially and also
1937from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

1958
1959\wxheading{Remarks}
1960
1961The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1962click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1963page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1964value has to be adjusted when the window is resized, since the page size will have changed.
1965
1966In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1967the thumb changes size to reflect the page size relative to the length of the document. When the
1968document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1969will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1970disappear.
1971
1972Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1973handling of pages and ranges.

2025
2026The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2027object length of the scrollbar. If you are implementing a scrolling window, for example, you
2028would adjust the scroll range when the window is resized, by subtracting the window view size from the
2029total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2030and usually the scrollbar will be automatically hidden.
