Hi, guys!
how do I change icons in a TreeViewer class? For example, if the node is collapsed, one icon is displayed, if expanded other.
thanks for your advice in advance.

You have to implement an ILabelProvider. Look at ILabelProvider,
LabelProvider in help.

yep, I know I have to implement this stuff, otherwise nothing would work. But could you be more specific?

Put this in your LabelProvider:

public Image getImage(Object element){
return treeViewer.getExpandedState(element) ? expandedImage :
collapsedImage;
}
