Hi,
Does anybody know how to make connections in Visual Editor ?, for example
I have JButton and JLabel on JFrame and I want to connect them with solid
line with an arrow (at design time) - how to do this ?
Regards

Thank you for information - so you saying that there is no easy way just
to draw line between two components (without code generation etc.) ? I've
tried to solve this problem - I can start connection from one component,
but when I try to connect with second component, connection disappear (I
think it's because I don't have Models - only EditParts). Any suggestions
appreciated !
Best regards

VE doesn't do connections. You can add events, e.g. JButton clicked
event -> run some code. When you add an event a listener is created and
then the developer can put any code they want in that listener.

So how should I implement this ? I know that I should subclass
AbstractConnectionEditPart - but I don't know what how to add new entry in
palette, because Connection tool is not visual java bean (it doesn't
extends Composite). I need to add to palette tool similar to "selection",
or "marque".
Thanx for reply

We don't recommend doing this. It is more than just "creating a
connection" that shows visually. It is code generation too. In fact you
must be able to re-interpret the code to find such a connection to show
visually because VE doesn't persist the model information, it only
persists the code.
It is a big deal to do this. VE very intentionally decided to NOT
support this kind of function from VisualAge because it looks cute in
small doses but it quickly gets out of hand and makes a mess of the
visual surface. It is better to not do this.
