[Gambas-user] Modify a control in another form

[Keith Clark]

How do I modify settings of a control on another form?  Let's say that I 
want to be able to control the number of rows and columns of a grid 
view, gvSampleGrid, on form, fGameGrid from form, fGameSetup.

Would it not be fGameGrid.gvSampleGrid.rows.count=10?

I am working with the book A beginner's Guide to Gambas but find it 
confusing on the basics.

Thanks.
