When you open Windows Explorer, then select some file or folder, then click its file name, an inline label-edit will be invoked. But there is an intentional delay before the textbox is displayed. Why?

First I thought its because I can move the mouse away until the textbox appears to cancel the edit, but it happens in any case.


I would guess that the delay is to distinguish clicks from double clicks.

  • This is correct. If you use Control Panel to alter the double-click speed (under "Mouse" properties) then the speed of the textbox appearing changes accordingly. – Andrew Leach Jul 26 '12 at 11:23
