Callback mechanism

[supplyondemand]

Hi!

I am new to EA scripting, so please bear with me.

I want to do two things:

1. Display a custom tooltip.
2. Display a custom window (for example like the predefined "Tagged Values" or "Notes" window) to display information that I can assemble according to the selected element.

Is there some kind of callback mechanism, meaning that the function will be invoked every time I select an element (with a reference to this element) or move the mouse over an element (to display the tooltip)?

Thank you!

No. IIRC Rational Rose had that neat callback which we used for quite a lot of things. But EA hasn't. You only get called if you're actually manipulating elements.

I don't think a custom tooltip is possible, but a custom window certainly is.
I use that feature to for the  EA Navigator.

Thanks a lot Geert.

Could you however give me some more specific pointers where I can find the "entry point", meaning the function that is called when I select an element and that does the window update? And how I define that this function is actually called?

Like I said I am really new to this.

                this.navigatorControl.BeforeExpand += new TreeViewCancelEventHandler(this.NavigatorTreeBeforeExpand);
                this.navigatorControl.NodeDoubleClick += new TreeNodeMouseClickEventHandler(this.NavigatorTreeNodeDoubleClick);
            }
            if (this.navigatorControl != null && this.model != null)
            {
                if (item != null)
                {
                    this.navigatorControl.setElement(item);
                }

            }
        }
