2cdac558 3wxWindow is the base class for all windows. Any children of the window will be deleted
4130b487
RR
4automatically by the destructor before the window itself is deleted.

2cdac558
RD
6Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7help text. These must not be called by a user program and are documented only for illustration.
4130b487
RR
8On several platforms, only a few of these handlers are actually written (they are not always
9needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
11platform can implement its native behaviour or just ignore the event if nothing needs to be
12done.

8a293590 252\func{virtual bool}{Close}{\param{bool}{ force = FALSE}}
a660d684
KB
253
254The purpose of this call is to provide a safer way of destroying a window than using
255the {\it delete} operator.
256
257\wxheading{Parameters}
258
259\docparam{force}{FALSE if the window's close handler should be able to veto the destruction
260of this window, TRUE if it cannot.}
261
262\wxheading{Remarks}
263
264Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
265choose whether to destroy the window.
266
267The close handler should check whether the window is being deleted forcibly,
268using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
269destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
270
271Applies to managed windows (wxFrame and wxDialog classes) only.
272
532372a3
JS
273{\it Note} that calling Close does not guarantee that the window will be destroyed; but it
274provides a way to simulate a manual close of a window, which may or may not be implemented by
275destroying the window. The default implementation of wxDialog::OnCloseWindow does not
276necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
277itself only hides the dialog.
278
279To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

292\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
293
294Converts a point or size from dialog units to pixels.
295
296For the x dimension, the dialog units are multiplied by the average character width
297and then divided by 4.
298
299For the y dimension, the dialog units are multiplied by the average character height
300and then divided by 8.
301
302\wxheading{Remarks}
303
304Dialog units are used for maintaining a dialog's proportions even if the font changes.

1102\wxheading{Remarks}
1103
1104This member function is called in response to a keypress, if the window is active. To intercept this event,
1105use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
1106keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
1107
1108An example of using this function is in the implementation of escape-character processing for wxDialog,
1109where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
1110
1111Note that the ASCII values do not have explicit key codes: they are passed as ASCII
1112values.

1114This function is only relevant to top-level windows (frames and dialogs), and under

1175
1176This is an event handler function called when the user has tried to close a a frame
1177or dialog box using the window manager (X) or system menu (Windows). It is
1178called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1179that the application can also invoke the handler programmatically.
1180
1181Use the EVT\_CLOSE event table macro to handle close events.
1182
1183You should check whether the application is forcing the deletion of the window
1184using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1185destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1186If not, it is up to you whether you respond by destroying the window.
1187
387a3b02
JS
1188(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1189the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1190it is not possible to skip window deletion.)
1191
1192If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
1193let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
1194to return TRUE or FALSE depending on whether the close instruction was honoured or not.

1198The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
1199for backward compatibility with earlier versions of wxWindows. The
1200default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
1201destroying the window if it returns TRUE or if the close is being forced.

1488Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
1489even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong.

1491For example:
1492

1503
1504You can optimize painting by retrieving the rectangles
1505that have been damaged and only repainting these. The rectangles are in
1506terms of the client area, and are unscrolled, so you will need to do
1507some calculations using the current view position to obtain logical,
1508scrolled units.

1614When a window is resized, usually only a small part of the window is damaged and you
1615may only need to repaint that area. However, if your drawing depends on the size of the window,
1616you may need to clear the DC explicitly and repaint the whole window. In which case, you
1617may need to call \helpref{wxWindow::Refresh}{wxwindowrefresh} to invalidate the entire window.

2030An event handler is an object that is capable of processing the events

2032an application may wish to substitute another, for example to allow

2035
2036It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since

2180Let's say you wish to display 50 lines of text, using the same font.
2181The window is sized so that you can only see 16 lines at a time.
2182
2183You would use:
2184
2185{\small%
2186\begin{verbatim}
2187 SetScrollbar(wxVERTICAL, 0, 16, 50);
2188\end{verbatim}
2189}
2190
2191Note that with the window at this size, the thumb position can never go
2192above 50 minus 16, or 34.
2193
2194You can determine how many lines are currently visible by dividing the current view
2195size by the character height in pixels.
2196
2197When defining your own scrollbar behaviour, you will always need to recalculate
2198the scrollbar settings when the window size changes. You could therefore put your
2199scrollbar calculations and SetScrollbar
2200call into a function named AdjustScrollbars, which can be called initially and also
2201from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

2222
2223\wxheading{Remarks}
2224
2225The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2226click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2227page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2228value has to be adjusted when the window is resized, since the page size will have changed.
2229
2230In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2231the thumb changes size to reflect the page size relative to the length of the document. When the
2232document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2233will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2234disappear.
2235
2236Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2237handling of pages and ranges.

2292would adjust the scroll range when the window is resized, by subtracting the window view size from the
