[Gambas-user] GridView.ClientWidth yields incorrect size on Form_Open

[Denis Crowther]

Sure Lee,

Copied straight from a working program.

I 'think' the trick is to use the Arrange event.
Using -1 didn't work for me in the arrange event,
I haven't tested it anywhere else yet.


Public Sub tblTest_Arrange()

   With tblTest
     .Columns[0].Width = 0
     '.Columns[1].Width = 150
     .Columns[1].Expand = True
     .Columns[2].Width = 50
   End With

End

Regards
Denis
