Some controls are not available in the Java version;
multi-column treeview
sidebar
activex (of course)
hideshow
xaml
carousel
cube
internal window
toolbar
and chart , but other than that, they are indistinguishable. I'll try to throw up some screenshots running on windows / linux / mac. They look exactly alike.
I know the list of unavailable controls seems long but there a a few options. One is to look for methods to create similar acting controls with existing controls, or the other is to see if you can use outside controls.
Cheers!
