cursor moving and autosize of Image Display

[jingli]

I have LabVIEW 7.1 and vision7.1. I want the size of Image Display in the front panel to be auto enlarged when the cursor is moving into its field and to be auto shrunk when the cursor is out of it. how can I do?
thank you very much

Use an even structure with the following two event cases. (1) "Image Display":mouse enter (2) "Image Display":mouse leave. In event case (1), you programmatically zoom in, and in event case (2), you zoom out.

(If you want to pan around in the zoomed-in display as a function of mouse position, it gets slighly more complicated.)

I don't have vision, but the technique should be universal.

Here is a quick example in LabVIEW 7.1, is that what you had in mind?

Thank you very much.
I think it will do the work.
