I try dock property, but I can set 1 dock type only. Actually somtimes we need to set more than 1, ex: bottom and top/bottom and right/etc.
IMO, docking has 5 basic type (display in property):
- fill = stretch width and height to parent area
- top, bottom, left, right = stretch only which side is set to parent area
I hope my illustration attached can explain my proposal.
Thanks
