Hi,
I have the following questions in Logic Editor Example:
1. The LED component has popup menu commands ("Increment", "Decremenet"),
can you tell me where in the code adds those command to the LED component?
The OR, XOR,... gate does NOT have those commands.
2. Where in the code draws the line for the Connection? If I want to change
the line style (e.g. make it a dash line, or an arrow line), where should I
look?
3. If I put components (e.g. XOR gate, OR gate) om Flow Container, it layout
in a flow layout. Can I change it so that it keeps the co-ordinates (the
ones tha user draw)?
Thank you for your help.
Sam

The LogicContextMenuProvider is adding these to the menu.

Not in the example.

And who can I support "Drag-and-Drop" components? In current example, I need
to click on the palette menu to select the components, and I click again on
the diagram to draw it. How can I change the example to do drag-and-drop? I
drag a component and when I drop it, it will place the component on the
location of where I release the mouse.
p.s. I am trying to learn the GEF by understanding /changing the logic
editor example. Thanks for any help.

This is an example. We have a "flow" container not because it makes sense,
but to demonstrate the FlowLayout and the EditPolicy for it. Ignore the
details of the model ;-)
