Trinidad 1.0.9 Expand/Collapse Tree

[Wu, Billy]

Hi everyone,

 

I have a very simple question regarding Trinidad 1.0.9 Tree.  Do I need
to write any code to expand/collapse a tree node?  It seems like I need
to.  But looking at the demo, I can't find any code that does that.  It
seems like it is done automatically.  Does Trinidad keep track of the
state internally?  If I do need to write some code for this, is there a
good example for this?

 

Thanks,

 

Billy
