TreeBranch.setExpandedIcon("@images/iconfile.png") Doesn't work in Pivot 2.0

Hi All,

 

I am migrating pivot 1.5.2 application to pivot 2.0 and converting the
following statement in 1.5.2 (these two statements work just fine in
pivot 1.5.2):

 

myTreeBranch.setIcon("images/iconfile.png");

myTreeBranch.setExpandedIcon("images/expandedIconfile.png");

 

To

 

myTreeBranch.setIcon("@images/iconfile.png");

myTreeBranch.setExpandedIcon("@images/expandedIconfile.png");

 

For pivot 2.0.

 

The setIcon method works fine but I got the following exception for the
setExpandedIcon method:

 

java.lang.IllegalArgumentException: expandedIconURL is null.

Is this a bug in 2.0?

 

Thanks,

The '@' syntax only works in BXML. It means "load the image from a path that is relative to the current file". I think what you are trying to do is load the image from an absolute path (i.e. one that is relative to the classpath). You should use a string that starts with a "/" - the fact that the '@' symbol works is just a side-effect, since setIcon(String) simply drops the first character.

However, I have fixed the issue with setExpandedIcon(). Thanks for catching that.
