/*****************************************************************************
|
|
class CSimpleDividedView
|
|
Simplest divided view.
|
|
|
|
### Standard usage:
|
|
In Constructor, create the CSimpleDividedView from a template,
|
|
set the IDs and min size of subviews
|
|
|
|
It should be in the same level of hierarchy as the views it manages.
|
|
It does not do any drawing
|
|
|
|
It broadcasts msg_SubviewChangedSize after a successful drag. Hook it up
|
|
to your window manually (outside the RidL resource), because it is not a
|
|
LControl subclass. Do this only if you need to do something in response to
|
|
resize. For example, recalc the GrayBevelView.
|
|
|
|
timm has a more sophisticated class, divview.cp, which takes car of resizing
