Are there any better approaches I don't know of?

Hi,

I have a GEF viewer with large figure,
And an associated outline view for the same,

With outline view the application eats up cpu even while minimized,

Without outline view the application starts eating CPU once in focus with no user activity,

Is this right,
How can i find out what is eating the CPU,
a break point position in GEF or draw2d classes would be appreciated...

Thanks for the solution Pascal!  :)
That looks like a clean solution to my problem.
I will get back with my results in a week from now.

No problem.

Hello all,

I want to react on a click on a label in a figure and pass it to the corresponding editpart in order to create a request and change the model.
What is the best practice to do so? How would I dispatch the mouseClick event to the editpart?
Thanks in advance

I'm guessing you want some custom behavior on a single click of the figure, so I'll start from there. First of all, you need to have a selection tool entry in your palette. You need to modify the tool it gives you for your own SelectionTool. The default one does not ask the edit part for a command, and that's what we want here. So, subclass SelectionTool, and extend the #mouseDown() method as follow:
@Override
public void mouseDown(MouseEvent e, EditPartViewer viewer)
{
// Let the superclass treat it before you, so its state updates.
super.mouseDown(e, viewer);
Command command = getCommand();
getCommandStack().execute(command);
}
note: you may which to extend something else, such has #handleButtonUp(), or #mouseUp(). The #mouseDown() approach was only for quick testing. Also, I didn't do any error checking which you may or may not need.

Then, you need to tell the selection tool entry which tool to use. There is two way for that:
1- pass your own class to the #setToolClass() method (I had no luck with this tho)
2- subclass SelectionToolEntry and override #createTool as follow:
@Override
public Tool createTool()
{
Tool tool = new Test();
tool.setProperties(getToolProperties());
return tool;
}

Then, all you need is an edit policy on your edit part which understand the REQ_SELECTION and gives you the command.

Hope this helps.

wow, major typo. I meant:
note: you may wish to extend ...

1) install a SelectionEditPolicy on the EditPart - add a MouseListener to the figure's label which will toggle a boolean value - from the SelectionEditPolicy's ShowSelection methode read that boolean value of the figure and execute a command

So if someone has a nice and clean solution please feel free to answer!

Is it possible to combine Zest (particulary, layout managers) with GEF?
Is there any example of this?
