Double Click on the vertical separation line of a ListBox?

General

Yes, you are right, I want to adapt the column width.

But I need to get the DoubleClick Event on the vertical separation line of the ListBox.

Is it possible ?

And if so, how ?

Nota: resizing “automagically” the Column is feasable. (in a loop…)

use the mousedown event, and count the time between two clics

Thank you Jean-Yves…

at the mousedown event, store the time of the clic in a property
also check if the mouse is around a column line, and stor it’s position
at the next mousedown, check if the time is less than a doubleclic
then check if the mouse is still at the same position
if yes then fire a doublecliccolumn event

I will try in the afternoon when back home.
