I posted this on my blog (http://www.leifwells.com), but I thought I'd
try giving the Flashcoders list a shot at this, too.
We are trying to get a tool tip to work with a DataGrid component. And failing.
The project we are doing is a rather complex AS 2.0 project, so I
created this rather simple AS 1.0 version as a stand-alone example of
our problem. (you'll note that the setInterval() and
clearInterval() calls are commented to prove that they are not the
problem)
The FLA file with the code (below) can be downloaded at:
http://www.leifwells.com/zip/dg_problem.zip
THE PROBLEM: when you roll over the text in the cell a itemRollOut
event is getting fired a itemRollOver is also fired -- that's when
the cursor changes to the i-beam cursor.
For instance, if you test the FLA file and you move your cursor over
the area to the right of the price column, you'll see the tool tip
pop up just fine. But then try moving your cursor over the price or
the name. Keep moving it across the text. What a mess!
If anyone has experience with this issue or has issues with the way
that we are trying to accomplish this, feel free to shout.
