Re: [OpenMap Users] Re: Single Distance Line with the Distance Layer

Well, i try to make changes to the DistanceLayer by using a custom
DrawingEditorTool...

However, I've encountered a brick wall when I try to remove the old line...
please advise..

Perhaps there's another way, but the following is what I've experimented...
Code Snippets...
//imports....
public class DistanceDrawingEditorTool extends DrawingEditorTool {
    private List<EditableOMGraphic> drawnLines = new
ArrayList<EditableOMGraphic>();

    public DistanceDrawingEditorTool(EditorLayer layer) {
        super(layer);
    }

    @Override
    public boolean mouseClicked(MouseEvent e) {
        System.out.println("Total Count: " + drawnLines.size());
        //remove old line if present
        if (drawnLines.size() > 1) {
            EditableOMGraphic oldLine = drawnLines.get(0);
            //remove old line here....
            //BRICK WALL -> How to remove line?
        }

        return super.mouseClicked(e);
    }

    @Override
    protected OMDrawingToolMouseMode activateDrawingTool(String ttc) {
        OMDrawingToolMouseMode mouseMode = super.activateDrawingTool(ttc);
        drawnLines.add(getDrawingTool().getCurrentEditable());
        return mouseMode;
    }
}
