Hi,
Quoting Alan <[email protected]>:
The problem is that if more than one item is selected, say two, you have
to click on the second item twice for it to register when the button is
clicked.
You should look into the 'changed' signal of the treeselection object
instead of using the 'cursor-changed' signal of the treeview itself.
I've adapted your first example, see below.
hth,
Dieter
