Label to connector disappears. [message #125208]

Hi,

I have created a figure for my connectors.

public class XFigure
extends PolylineConnection {

private Label label;
private ConnectionLocator locator;

public XFigure() {
super();
}

public XFigure() {
super();

label = new Label("Connector label text");
locator = new ConnectionLocator(this);
locator.setRelativePosition(PositionConstants.SOUTH);
locator.setGap(15);
this.add(label);
}

public void paintFigure(Graphics g) {
super.paintFigure(g);
locator.relocate(label);
}

}

The text "Connector label text" appears fine just below the connector line.
When I move my source or target, sometimes half the text disappears but when
I select the connector the text appears. Can somebody help me with the
problem.

thanks
Khurrum

You cannot relocate the figure during painting. The connections bounds have
already been calculated, and they will clip the child.
Instead, use a DelegatingLayoutManager on the connection. This will get
tied in before the new bounds are calculated.
