Double-click on edit field

How can I catch a double click when the cursor is placed over an edit field? The normal double-click handler doesn't respond. I need to open a dialog window following a double click on an edit control.

Well, I have good news and bad news. The bad news is that I don't think you will be able to pick up the double click in an edit field. The edit field is a unique OPO object, and to the best of my knowledge it does not respond to double clicks.

The good news is that it is fairly easy to pick up another key stroke combination with the OnKey() method. I advise using this technique.

If you want to return the focus to another field when the dialog box closes, you will have to use the SetFocus() method before you call the dialog box. This is just an OPO peculiarity (or bug . . .).
