something like: amount=CountGadgetColumns (#ListIcon_1)

Hope you have an Idea

One way is to ask the header control for the number of items:

headerhWnd=SendMessage_(GadgetID(1),#LVM_GETHEADER,0,0)
debug sendmessage_(headerhWnd, #HDM_GETITEMCOUNT,0,0)

Regards.

The #LVM_GETHEADER message simply retrieves the handle of the header control which is attached to the ListIcon gadget.

The column headings you see in a ListIcon gadget are actually part of a Windows header control which has been bound to the ListIcon. You can use header controls almost anywhere, not just with ListIcons.

Anyhow, the number of columns in a ListIcon is simply the number of items in the attached header control.

In 'MoreListIconGadget'-Lib you find a lot of functions like 'GetColumnsNumber(#Gadget)' and more.
