Hi,
how can I do this?
When I click on popup menu and I don't change a content, than print "You didnt change it". When I change the content, than print "You changed it".
thank you

save the Value property of the menu. In the callback, compare the new Value property to the saved property.
Now if you need to be able to detect that the use moved onto the popup menu but did not click on anything or pressed escape to avoid selecting anything, then that task is more complicated.
