Question

I have a JTable where I can select one or more cells. I also want to react on double-click for doing some extra action for the selected cells. But the problem is, when the user double-clicks, the selection changes to the clicked cell. But I want to keep the prior selection on double-click, so I can handle the double-click for all selected cells.

EDIT:
Related to this question:
Java : ignore single click on double click?
But I hope, there is a better/easier solution for my case.

Answer 1

The problem is, that on the first click the first event goes out. A bit later the second click might come or not. So the first click event does know nothing. As in the proposed solution a timer might do.

What also might do is on the first click to select nothing, but invoke a special selection event a bit later.

SwingUtilities.invokeLater(myRunnable);

and on handling the double click/myRunnable the true selection. Timing might be unavoidable though.
