Hi,  
I’ ve created a TreeList that shows the files in a directory. How can I  
create a context menu that pops up, when I right-click on a selected  
item? I know how to create the popup menu, but how can I prevent it to  
get shown when I click somewhere else than the item? Do I have to  
remember the items I selected and then check if it’ s under the cursor  
when right-clicking?

Thanks,  
Alexander F…

I think that I’d just call FXTreeList#getItemAt(event.win\_x,  
event.win\_y) to determine which item was right-clicked. If the user  
right-clicked somewhere outside of an item, getItemAt() ought to  
return nil.

Thanks,  
it works, after a while of trying and modifying. I’ m on my way into the  
FXRuby library and still have some newbie problems with the events and  
their handling. But I’ m going to manage that.  
Thanks,  
Alex.

Hi,  
but now another question:  
When I selected an item, all works fine, but the menu always pops up,  
when I right-clicked in the item’ s row. That doesn’ t happen above or  
below the row. What happens here?

Thanks,  
Alex.
