Normally a listbox doesnt support much in the way of live resizing of rows or columns if you dont have a header row.
Turns out that for something else I’m working on I needed to be able to resize things and NOT have a header row – and also make it possible to resize rows as well by clicking & dragging.
And the result so far is this
Live resizing by clicking & moving the grids themselves !
There is no header on this listbox either.
I’ll see if I can release this as a stand alone item.
