a View to separate its subviews horizontally by a movable bar
|
|
|
54 |
to adjust the size-ratios.
|
|
|
55 |
The bar-handle is either an exposed knob (knobStyle == #motif)

56 |
or the forms defined in Scroller (knobStyle ~~ #motif)
|
|
|
57 |
or nothing.

The subvies dimensions MUST be given as relative sizes;
