[Gambas-user] Chronic columnview Woes

[Fabien Bodard]

In fact I think I need a better explanation or an example...
What do you really want ?

To generate a kind of elementclick event?

Normally you just have to do.:
$sKey = cvw.Item.Key
In the cvw_Click event
And then use the value of $sKey in the cvw_menu event

Or maybe I have missed something and so tell us more

Best regards,
Fabien Bodard
