Popup menu button - how to prepare the button?

[dunbarx at aol.com]

Hi.


This is really klunky, but maybe you can refine it:




on mouseup
   wait 15
   if not the mouseClick then focus on nothing
end mouseup


LC creates a temporary field that overlays the "cell" in a table field. That is where the entered data goes, and the the engine updates the table field itself when you move on. The trick is to not allow that field to have focus on a single click.


There are likely better ways to do this...

Thanks for the clarification, Klaus - that works perfectly.

My next challenge is that single left click on a basic table field highlights 
the row (good) and puts the item into edit mode (not desired). How might I go 
about suppressing this default behaviour and force the need for a double-click 
to enter item edit mode?
Best,
Keith..
