Class TreeCollapseImprint

java.lang.Object
  cz.cuni.pogamut.posh.view.TreeCollapseImprint

public class TreeCollapseImprint
extends Object

This class is an attempt to remember which widgets were collapse in the widget tree so I can try to restore collapse state of tree after some modifications in source view.

Basically :

• Graph view is notified about view switch
• Graph view will create a TreeCollapseImprint to store which nodes in the tree were collapsed
• User will modify the source of posh plan
• User will switch to graph view
• Graph view will regerate the graph of posh plan or announce syntax error.
• Graph view will use TreeCollapseImprint to colapse the tree, but since tree has changed, there will be some changes
