bbdoc: noddybox.mwidget
about: <p>Provides a simply class based interface to the MaxGUI.  Note that all widgets have create type methods.  For these to work correctly with
sub-classes they must be called through a new operation, e.g.</p>
<pre>
Type MyApp Extends TMWindow
&nbsp;&nbsp;&nbsp;&nbsp;Method OnClose(e:TEvent)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;closed=Confirm("Really quit?")
&nbsp;&nbsp;&nbsp;&nbsp;End Method
End Type

Local window:TMWindow=New MyApp.Create("Test",100,100,640,400)
MWidgetMainLoop(window)
</pre>
<p>
There are two methods of getting events.  One is to subclass and override the events, as with the @OnClose() above.  The other is to set
function pointers in the matching event lists, @OnCloseEvent in this instance.  For instance:
</p>
<pre>
Function OnClose(o:TMWidget)
&nbsp;&nbsp;&nbsp;&nbsp;Local w:TMWindow=TMWindow(o)
&nbsp;&nbsp;&nbsp;&nbsp;w.closed=Confirm("Really quit?")
End Function

Local window:TMWindow=New TMWindow.Create("Test",100,100,640,400)
window.OnCloseEvent.Add(OnClose)
MWidgetMainLoop(window)
</pre>
<p>
When using the function callback method of capturing events, the parameters to the function are the same as the overridable method with the addition
of the managed widget which is passed in as the first argument.
</p>
