detecting when a control is drop over an Xcontrol

[Jonathan Borduas]

Hello,

I try to detect the following action in edit mode:

I took control and moves over an xcontrol and then I released.

Note that in my program, it must be the Xcontrol that detects the action.

So I tried with the mouse up event, but since it happens on the control moved, the mouseup event is not triggered.

After trying several strategies that have not given the desired results.

Have you tried the Drag/Drop Events?

Have you tried the Drag/Drop Events?

I'm not familiar with these events, I thought they were for drag/dropping data.

I don't know if the drag events will work or not, but if not, I think you might have to do this with polling. You can use the initialization of the XControl to spawn a running VI which will use the mouse input VIs to monitor whether the mouse button is released when the VI is front most and the cursor is over the XControl. I'm assuming that if you grabbed a control, you will be able to get a reference to it using the panel's Selection List[] property.

You can use the uninit code to destroy the process.

Sounds good. Do you have a simple example you can upload? It might help someone else in the future.
