Double click event in the Tree Active-X control

[Ramkumar Damodaran]

Hi,

I know that the Tree control in LabVIEW control palette has Double click event but the same event is not available for TreeView Active-X control. Is it possible to create the Double click event by any other way?

Kindly revert if you have any idea.

Ramkumar,

I understand that you want to preform some action off of a double click event for a TreeView control in an ActiveX container. What do you hope to accomplish with the double click event? Are you trying to open an program/file from a tree? If we know your end goal, there may be an easy solution.

Best Regards,

Thanks Chris for your reply.

Actually I need to open a new window on double clicking the tag in the TreeView active-x control. In that new window user can do someother function. Is it possible to do that?

If yes, kindly explain how it can be done.

You could do what Windows does if you can get more information on the single click event (if you have one).  On a single click event check previous click history for a double click match.  Save the X and Y coordinates and a rough idea of the time on each click.  When a new click comes in check the delta X and Y and if within say 2 pixels also check the time delta and if within a set limit (25ms?) this is now a double click.  Otherwise this is single click and when done save new data to next click iteration (probably through a shift register)...
