[Glgui-dev] a few more updates

[sfranke <sf...@us...>]

added a couple simple but cool classes:
 DraggableViewFrame
 DraggableFrame

I'm very happy about how easily these were added.  It tells me that I did
at least one or two things right in the underlying design.

You can select the active frame based on a string name, like selecting
resources.

The callback functions are much more robust and useful now.  It's similar
to win32 and glut, where you have a function that gets passed frameIDs
when they have been clicked (or are being dragged).  They have arbitrary
parameters (based on the type of the frame) that are also passed back.

I won't know how well all this really works until I (or someone
else) implements something in a real (or semi-real) app.  But I feel
pretty good about it.

I'm going to write a list box class now, and that is the last low-level
frame I'm going to do.  Then I start working on the controls which are
higher level classes (though they inherit from CUI_Frame to get the base
functionality they need) that automatically create and handle a number of
frames below them.

These are the controls I have planned right now:
	menubar
	popup menu
	chooser
	spinner
	toggle button
	radio button group
	textfield (one liner)
	console

Any other suggestions?  Or any input at all?
