Can someone explain the following? In the script below, in the first if/then structure, the mouse moving away from a piece of linked text causes the backgroundColor of that linked text to reset to empty. But the mouse is only moving off the linked text, not out of the field. This makes me think a piece of linked text is a control which receives a mouseLeave message. Is this correct?
But then with the repeat structure below that, only by the mouse actually leaving the field does the backgroundColor of all lines reset to empty. Which leads me to think that the linked text it was hovering over was not a control.
How does this work? Thanks Mark
on mouseLeave -- unhighlight any currently highlighted text:
if storedHilitedChunk is not empty then do "set the backgroundColor of" && \ storedHilitedChunk && "to empty" put empty into storedHilitedChunk end if
repeat with y = 1 to 3 repeat with x = 1 to the number of lines of field y set the backgroundColor of line x of field y to empty end repeat end repeat
pass mouseLeave end mouseLeave
Sorry I'm seeing this and responding so late. The above looks like a mutation of the highlight-text script that I wrote for the original documentation.
The mouseLeave handler actually *isn't* invoked when you move the mouse off of linked text but leave it inside the field. Take a look in the script for the companion mouseMove handler, which has some similar code. The mouseMove handler, not mouseLeave, controls the unhighlighting in this case.
The mouseLeave handler is in the way of being a backup, to make sure that moving the mouse quickly out of the field doesn't leave "highlight droppings" if the mouse is moving too fast to trigger mouseMove before it leaves the field.
