[Gambas-user] Tableview problem

[Peter Peyotle]

Thank you for your answer. I solved the problem. The cells have a continuous internal top component. then top is bigger than the field of vision. my control must be placed in the field of view. a cell is (unfortunately) not a container. So I have to insert the control relative to the scroll position. this is 
tableview [a, b] .y - tableview.scrollY. 
that's it :-), juhuuuuu
