Re: [bpel-dev] How to change the default behavior of LeafBorder.paint()

[Michael Illiger2 <MILLIGER@xxxxxxxxxx>]

Hello,

there needs to be some "hard-coding"
here because you have to find out whether there are any extension point
implementers. Your code looks good to me  - evtl. you could put this
stuff into org.eclipse.bpel.ui.extensions.BPELUIRegistry. That's
where we handle all our other extension-points...

Mit freundlichen Grüßen / Kind regards

Hello, Michael,

thank you for your answer.
I still have a question about creating an extension point in bpel.ui.

I have defined an extension point with name "customvisual" in
plugin.xml of bpel.ui

I have added following codes in org.eclipse.bpel.ui.editpart.border.LeafBorder
to create an instance of the extension. 
    protected void getExtensionLeafBorder() {
        
        instance = null;
        
        instance =  (LeafBorder) BPELUIRegistry.readCustomvisual("extension.leafborder");
        if (instance == null) {
            return ;
        }
    }

This instance is used in paint(IFigure figure, Graphics graphics, Insets
insets) to adjust the visualization
of the activity nodes.
My question is: is there a way to avoid modifying the source code of org.eclipse.bpel.ui.editpart.border.LeafBorder?
Because the hardcoding is always bad.

thanks!

Zhen and Ting

Hello Ting, 

as of today we don't have the possibility to adjust the visualization of
the activity nodes using extension points. 
So the answer is, yes - you would have to define an extension point in
bpel.ui.
