Get appropriate cell coordinates in List Control while mouse moving

[C.D.]

Hi,

in a List Control of LabVIEW 7.1 I want to show full lenght of truncated entrys via tip strip (like Windows explorer). To this I want to set tip strip by entry of List Control while moving mouse pointer over List Control.

My problem: In Event Case "Mouse Moving" property node provides only XY-coordinates of LV front panel. But I need cell coordinates of List Control who mouse pointer cross over.

Can anybody help? Thanks.

Hi C. Dietz,

you can calculate the row by divide the y value by the row height.

Hi Mike,

thank you for reply.

I tried that already but title of control element and title of columns are unknown dimensions. So I don't know the XY-coordinates from left upper corner of first data cell.

Hi Christian,

can you upload an example of what you have done so far?

Hi Mike,

thank you for your activity (keine Entschuldigung für den Anhang in deutsch, damit komme ich sogar besser zurecht )

This solution works. My initial problem was the unknown offset to first row (see attachement). I hoped this offset can obtain programmatically. Finally I found the offset approximately. It works exactly too.

Hi Christian,

to get the height of the caption see the attached picture. I think the height of the column header is the same as all other rows.

I'm not sure this exist in LabVIEW 8.5:
Active row position
And another reason to upgrade to LabVIEW 8.x:
Get mouse position

Maybe this will do:
