Hi All,

I am Generating a flowchart of any given input source code using JDiagram .
I want to hide a part of flowchart, I have already tried

But my problem is that : - After using node.setExpandable(true) when I click on some node it will shirnk the whole diagram under it. But i want that only a part of diagram to collapse on clicking that node, and the portion above and below the required portions remains the same.

For example if a block conatins loop statements . Now If one wants to show detaiiled
statemts of that loop only, and wants that remaing diagram remains the same.
I am not clear with the approach,How do I proceed. Are there any other method by
which I can achive this .

If you provide me some sample code lines, it would be more beneficial for me.


Please Guide me.

Hi , I havnt Got , what u described in the reply, Please be more elaborative.

Hi,
   I have used nodeClicked() method in DiagramListener, and in this method
   i am changing setExpanded(true/false) properties of ShapeNodes, to hide respect nodes and show others.
  I am able to hide the nodes i want ,by changing there Expanded properties or setting setVisible(false),
  The problem is :- "If i am hiding the nodes , The nodes which are not hided retains there location ,
there location doesnot change accordingly."


For eg.
If there are 8 nodes in my flow chart
  I want to hide 3,4,5 nodes and want 1,2,6,7,8 nodes to be visible when I click on 2nd node, 
  so 6th node should take position of  3rd node while the 3,4,5 are collapsed.
As soon as 3,4,5 are expanded 6 should retain its old location(i.e after 5).

I am able to hide the nodes but not able to change the location of 6th node to 3rd node and again adjust 6th node's position after 5th(when expanded)

Dear Stoyo,
I am Not using Tree Layout (infect i am not using any layout) . I embedded the class which extends DiagramView into my GUI,and  which is a swing based GUI.

Please Guide me , what to do ?
