3 wxWindow is the base class for all windows. Any children of the window will be deleted
4 automatically by the destructor before the window itself is deleted.
6 Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
7 help text. These must not be called by a user program and are documented only for illustration.
8 On several platforms, only a few of these handlers are actually written (they are not always
9 needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
10 the respective event as usual and call
\helpref{wxEvent::Skip
}{wxeventskip
} so that the native
11 platform can implement its native behaviour or just ignore the event if nothing needs to be

25 The following styles can apply to all windows, although they will not always make sense for a particular
26 window class or on all platforms.

}\label{wxwindowclose

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

292 Converts a point or size from dialog units to pixels.
294 For the x dimension, the dialog units are multiplied by the average character width
295 and then divided by
4.
297 For the y dimension, the dialog units are multiplied by the average character height
298 and then divided by
8.
302 Dialog units are used for maintaining a dialog's proportions even if the font changes.
303 Dialogs created using Dialog Editor optionally use dialog units.
305 You can also use these functions programmatically. A convenience macro is defined:

1002 use the EVT

1003 default function to achieve default keypress functionality.
1005 Note that the ASCII values do not have explicit key codes: they are passed as ASCII

1034 This member function is called in response to a keypress, if the window is active. To intercept this event,
1035 use the EVT
\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
1036 keypress, call
\helpref{wxEvent::Skip
}{wxeventskip
} to allow default processing.
1038 An example of using this function is in the implementation of escape-character processing for wxDialog,
1039 where pressing ESC dismisses the dialog by
{\bf OnCharHook
} 'forging' a cancel button press event.
1041 Note that the ASCII values do not have explicit key codes: they are passed as ASCII
1044 This function is only relevant to top-level windows (frames and dialogs), and under
1045 Windows only. Under GTK the normal EVT
\_CHAR\_ event has the functionality, i.e.
1046 you can intercepts it and if you don't call

1047 the window won't get the event.

}{\param{wxCloseEvent\&

1106 This is an event handler function called when the user has tried to close a a frame
1107 or dialog box using the window manager (X) or system menu (Windows). It is
1108 called via the
\helpref{wxWindow::Close
}{wxwindowclose
} function, so
1109 that the application can also invoke the handler programmatically.
1111 Use the EVT
\_CLOSE event table macro to handle close events.
1113 You should check whether the application is forcing the deletion of the window
1114 using
\helpref{wxCloseEvent::GetForce
}{wxcloseeventgetforce
}. If this is TRUE,
1115 destroy the window using
\helpref{wxWindow::Destroy
}{wxwindowdestroy
}.
1116 If not, it is up to you whether you respond by destroying the window.
1118 (Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
1119 the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
1120 it is not possible to skip window deletion.)
1122 If you don't destroy the window, you should call
\helpref{wxCloseEvent::Veto
}{wxcloseeventveto
} to
1123 let the calling code know that you did not destroy the window. This allows the
\helpref{wxWindow::Close
}{wxwindowclose
} function
1124 to return TRUE or FALSE depending on whether the close instruction was honoured or not.
1128 The
\helpref{wxWindow::OnClose
}{wxwindowonclose
} virtual function remains
1129 for backward compatibility with earlier versions of wxWindows. The
1130 default
{\bf OnCloseWindow
} handler for wxFrame and wxDialog will call
{\bf OnClose
},
1131 destroying the window if it returns TRUE or if the close is being forced.

2053 The window is sized so that you can only see
16 lines at a time.
2059 SetScrollbar(wxVERTICAL,
0,
16,
50);
2063 Note that with the window at this size, the thumb position can never go

2066 You can determine how many lines are currently visible by dividing the current view
2067 size by the character height in pixels.
2069 When defining your own scrollbar behaviour, you will always need to recalculate
2070 the scrollbar settings when the window size changes. You could therefore put your
2071 scrollbar calculations and SetScrollbar
2072 call into a function named AdjustScrollbars, which can be called initially and also

2097 The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
2098 click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
2099 page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
2100 value has to be adjusted when the window is resized, since the page size will have changed.
2102 In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
2103 the thumb changes size to reflect the page size relative to the length of the
document. When the
2104 document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
2105 will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)

2162 The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
2163 object length of the scrollbar. If you are implementing a scrolling window, for example, you
2164 would adjust the scroll range when the window is resized, by subtracting the window view size from the
2165 total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
2166 and usually the scrollbar will be automatically hidden.
