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.

129Note that wxWindows maintains the stack of windows having captured the mouse
130and when the mouse is released the capture returns to the window which had had
131captured it previously and it is only really released if there were no previous
132window. In particular, this means that you must release the mouse as many times
133as you capture it.

8a293590 257\func{virtual bool}{Close}{\param{bool}{ force = FALSE}}
a660d684
KB
258
259The purpose of this call is to provide a safer way of destroying a window than using
260the {\it delete} operator.
261
262\wxheading{Parameters}
263
264\docparam{force}{FALSE if the window's close handler should be able to veto the destruction
265of this window, TRUE if it cannot.}
266
267\wxheading{Remarks}
268
269Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
270choose whether to destroy the window.
271
272The close handler should check whether the window is being deleted forcibly,
273using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
274destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
275
276Applies to managed windows (wxFrame and wxDialog classes) only.
277
532372a3
JS
278{\it Note} that calling Close does not guarantee that the window will be destroyed; but it
279provides a way to simulate a manual close of a window, which may or may not be implemented by
280destroying the window. The default implementation of wxDialog::OnCloseWindow does not
281necessarily delete the dialog, since it will simply simulate an wxID\_CANCEL event which
282itself only hides the dialog.
283
284To guarantee that the window will be destroyed, call \helpref{wxWindow::Destroy}{wxwindowdestroy} instead.

295
296\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
297
298Converts a point or size from dialog units to pixels.
299
300For the x dimension, the dialog units are multiplied by the average character width
301and then divided by 4.
302
303For the y dimension, the dialog units are multiplied by the average character height
304and then divided by 8.

306\wxheading{Remarks}
307
308Dialog units are used for maintaining a dialog's proportions even if the font changes.

477This method is useful for visual appearance optimization (for example, it
478is a good idea to use it before inserting large amount of text into a
479wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all
480controls so it is mostly just a hint to wxWindows and not a mandatory

1187%%
1188%% This is an event handler function called when the user has tried to close a a frame
1189%% or dialog box using the window manager (X) or system menu (Windows). It is
1190%% called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
1191%% that the application can also invoke the handler programmatically.
1192%%
1193%% Use the EVT\_CLOSE event table macro to handle close events.
1194%%
1195%% You should check whether the application is forcing the deletion of the window
1196%% using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
1197%% destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
1198%% If not, it is up to you whether you respond by destroying the window.
1199%%
1200%% (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1201%% the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1202%% it is not possible to skip window deletion.)
1203%%
1204%% If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to

1500%%
1501%% Use the EVT\_PAINT macro in an event table definition to intercept paint events.
1502%%
1503%% Note that In a paint event handler, the application must {\it always} create a \helpref{wxPaintDC}{wxpaintdc} object,
1504%% even if you do not use it. Otherwise, under MS Windows, refreshing for this and other windows will go wrong.
1505%%
1506%% For example:
1507%%
1508%% \small{%
1509%% \begin{verbatim}
1510%% void MyWindow::OnPaint(wxPaintEvent\& event)
1511%% {

1514%% DrawMyDocument(dc);
1515%% }
1516%% \end{verbatim}
1517%% }%
1518%%
1519%% You can optimize painting by retrieving the rectangles
1520%% that have been damaged and only repainting these. The rectangles are in
1521%% terms of the client area, and are unscrolled, so you will need to do
1522%% some calculations using the current view position to obtain logical,
1523%% scrolled units.

1526%%
1527%% {\small%
1528%% \begin{verbatim}
1529%% // Called when window needs to be repainted.

1726An event handler is an object that is capable of processing the events

1729central implementation of event-handling for a variety of different
1730window classes.

1732\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows

2070An event handler is an object that is capable of processing the events

2072an application may wish to substitute another, for example to allow

2238Let's say you wish to display 50 lines of text, using the same font.
2239The window is sized so that you can only see 16 lines at a time.
2240
2241You would use:
2242
2243{\small%
2244\begin{verbatim}
2245 SetScrollbar(wxVERTICAL, 0, 16, 50);
2246\end{verbatim}
2247}
2248
2249Note that with the window at this size, the thumb position can never go
2250above 50 minus 16, or 34.
2251
2252You can determine how many lines are currently visible by dividing the current view
2253size by the character height in pixels.
2254
2255When defining your own scrollbar behaviour, you will always need to recalculate
2256the scrollbar settings when the window size changes. You could therefore put your
2257scrollbar calculations and SetScrollbar
2258call into a function named AdjustScrollbars, which can be called initially and also
2259from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

2280
2281\wxheading{Remarks}
2282
2283The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2284click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2285page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2286value has to be adjusted when the window is resized, since the page size will have changed.
2287
2288In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2289the thumb changes size to reflect the page size relative to the length of the document. When the
2290document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2291will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
2292disappear.
2293
2294Currently, this function should be called before SetPageRange, because of a quirk in the Windows
2295handling of pages and ranges.

2350would adjust the scroll range when the window is resized, by subtracting the window view size from the

2412The second form is a convenience for calling the first form with default

2417by wxWindows, or that the current value of the dimension should be used.
