Hi,
I want to make some hard calc with some values, but only with visible items from a ListIcon gadget.
Is possible retrieve this data?..
A 'fake' of results will be this
Thank you in advance

On Windows you can use the LVM_HITTEST message for a point such as 5,5 and it will return the item found there, which will be your first visible item. For the last one, you can use a point such as 5, GadgetHeight(listicon)-5. For other OS's, dunno.

There's also the #LVM_GETTOPINDEX and #LVM_GETCOUNTPERPAGE messages.

Netmaestro, Srod, very thank you. But, for now, I would like to make my app for Windows/Linux, so I'm thinking to remake the frontend of my app.
Again, thankyou for answers.
