Grasshopper

algorithmic modeling for Rhino

I have recently upgraded to the latest version of grasshopper. I hadn't upgraded in a while. I now find that my components which had a member that was derived from GH_ComponentAttributes no longer bring up a dialog box(winform) when double clicked. I override:

public override Grasshopper.GUI.Canvas.GH_ObjectResponse RespondToMouseDoubleClick(Grasshopper.GUI.Canvas.GH_Canvas sender, Grasshopper.GUI.GH_CanvasMouseEvent e)

This was working great in the previous release but no longer seems to. Any ideas on how i can get my dialog boxes working again?

Hi Erik,

 

have you compiled against the new version? If yes, I assume there are no errors or warnings? If no, can you please test that?

Yes I am compiling using version 1.0.0.20. and i get no errors or warnings at compile time.

To be more exact my code is as follows:

 

public class resEdges : GH_Component
    {

        public resEdges()
            : base("Restrain Edges", "ResEdge", "Restrain Edges", "RhinoBIM", "DOFs")
        {
            base.m_attributes = new HelperAttributes(this);
        }

 

and then in the helper attributes class i have:

class HelperAttributes : GH_ComponentAttributes
    {
        resEdges c;
        public HelperAttributes(resEdges _c)
            : base(_c)
        {
            c = _c;
        }
        public override Grasshopper.GUI.Canvas.GH_ObjectResponse RespondToMouseDoubleClick(Grasshopper.GUI.Canvas.GH_Canvas sender, Grasshopper.GUI.GH_CanvasMouseEvent e)
        {
            Rhino.RhinoApp.WriteLine("double click called\n");
            c.ShowDialog();
            return base.RespondToMouseDoubleClick(sender, e);
        }
    }

 

But Rhino fails to write the line "double click called"

Thanks

Ahhh, it's because you're being a naughty boy!

 

You're not supposed to assign the m_attributes field from the constructor, you're supposed to override the CreateAttributes() method.

 

public override void CreateAttributes()

{

  m_attributes = new HelperAttributes(this);

}

 

the reason it used to work is because my default implementation of CreateAttributes checked to see whether the m_attributes field had already been set, and wouldn't overwrite if it had. Now it always assigns new attributes regardless, so your attributes were being overwritten with the default ones.
