Custom compound figure / accessors [message #170609]

Hi,

Suppose I have a Custom Figure containing another figure (a label).

class MyFigure extends Figure {
// ...
Label getContainedLabel() { //... };
}

How would I access that figure (like with Child Access) to use it as
say a Diagram Label?

Thanks,
Jelle.

Hello Jelle,

You have to create:
- Custom figure in your figure descriptor
- Figure accessor in this figure descriptor with the accessor property set
to "getContainedLabel"
- Custom figure in this Fgiure Accessor with Qualified Class Name "org.eclipse.draw2d.Label"
(you can create Label figure instead if you change return type of getContainedLabel
to WrapLabel)
- FigureAccessor in the parent figure descriptor. This accessor should reference
inner label custom figure (child of Fgiure Accessor) as a Figure.

As a result you should be able to use child label of the Custom figure in
a label mapping via corresponding FigureAccessor.
