Hi Derrell,
thanks for your post. I'm using quite similar way except in dblclick
handler. What's happen if I double click to empty area (not list item
in list) and where e.getTarget() will point ? (I think to list
itself).
Correct way for me is something like this:
list.addListener("dblclick", function(e)
{
if (!(e.getTarget() instanceof qx.ui.form.ListItem)) return;
// ... now e.getTarget() is list item ...
// ... my code ...
});
Is this correct or there is better solution?
Cheers
- Petr
