Hi,

Why not useing TableViewer#editElement(Object,int). Please let's follow
up on JFace-questions on the eclipse.platform.jface-Newsgroup.

Oh iŽm sorry, next time i will use the jface newsgroup.

I already used editElement() but the problem is that when i click with my
mouse on a special cell, this cell should be edit, not the first one. If i
enter the table in another way (i.e. press TAB) then the first cell should
be editet.

So i had the idea that i implement a check in the focusGained method if
the focus was gained by mouse or by Tab, but i couldnt find anything in my
event class which could help me :-(

I don't think that focus gained is a good strategy because you receive
this event when ever an editor is open and closed.

I'm not sure either how to implement this feature without experimenting
with the various events.

hey,

well i also came to this point, so i thought about other strategies or
events. I thought about using the traverse listener but i cant use it
since its only active when iŽm already in the table, i will experiment
with some other listeners. Anyway thanks for your help, if you get an idea
just tell me ;-)
Greetz,
Thomas
