}\label{wxwindowclose
}
210 \func{virtual bool
}{Close
}{\param{const bool
}{ force = FALSE

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

252 Converts a point or size from dialog units to pixels.
254 For the x dimension, the dialog units are multiplied by the average character width
255 and then divided by
4.
257 For the y dimension, the dialog units are multiplied by the average character height
258 and then divided by
8.
262 Dialog units are used for maintaining a dialog's proportions even if the font changes.
263 Dialogs created using Dialog Editor optionally use dialog units.
265 You can also use these functions programmatically. A convenience macro is defined:
269 #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)

333 to a list of windows to be deleted on idle time, when all the window's events
334 have been processed. This prevents problems with events being sent to non-existant

}{\param{wxCloseEvent\&

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

1918 Let's say you wish to display
50 lines of text, using the same font.
1919 The window is sized so that you can only see
16 lines at a time.
1925 SetScrollbar(wxVERTICAL,
0,
16,
50);
1929 Note that with the window at this size, the thumb position can never go
1930 above
50 minus
16, or
34.
1932 You can determine how many lines are currently visible by dividing the current view
1933 size by the character height in pixels.
1935 When defining your own scrollbar behaviour, you will always need to recalculate
1936 the scrollbar settings when the window size changes. You could therefore put your
1937 scrollbar calculations and SetScrollbar
1938 call into a function named AdjustScrollbars, which can be called initially and also
1939 from your
\helpref{wxWindow::OnSize
}{wxwindowonsize

1963 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
1964 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
1965 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
1966 value has to be adjusted when the window is resized, since the page size will have changed.
1968 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
1969 the thumb changes size to reflect the page size relative to the length of the
document. When the
1970 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
1971 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
1974 Currently, this function should be called before SetPageRange, because of a quirk in the Windows
1975 handling of pages and ranges.

2028 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2029 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2030 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2031 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2032 and usually the scrollbar will be automatically hidden.
