Code:
obj
    MouseEntered()
        var/icon/I=new(icon='icon.dmi',icon_state="select", name="Sel")
        src.overlays.Add(I)
    MouseExited()
        for(var/icon/I in src.overlays) if(I.name=="Sel")// error: I.name: undefined var
            src.overlays.Remove(I)


Problem description:

Something like this is impossible, but is any other idea for this? I know icon don't support name var, i can do this with use obj's, but i'm not sure it's good way.

The image proc might be what you're looking for.
However, also, you can use the {} tags after declaring a new object to define properties.

Sorry, i resolve my all issues... i just use image proc.Thanks for (now useless) help :D

    MouseEntered(location,control,params)
        if(control=="DBPaneTileset.DBPaneTileset")  if(usr.client)
            var/image/I=image('icons.dmi',src,"select",src.layer)
            I.name="select";usr.client<<I
    MouseExited(location,control,params)
        if(control=="DBPaneTileset.DBPaneTileset")  if(usr.client)
            for(var/image/I in usr.client.images)   if(I.name=="select")    {usr.client.images-=I;del I}

Quick tip, the overlays list is always an internal type called an appearance. You can't iterate through the overlays list using an /image, /icon, or /atom filter, because the types in that list are none of those things.

Further, you should never be iterating through an entire list in order to find an object you want to remove.

To do what you are looking to do:

client
    var/tmp
        image/selection_icon
    New()
        . = ..()
        if(.)
            selection_icon = image('icon.dmi',"select")
            src << selection_icon
    Del()
        selection_icon.loc = null
        images -= selection_icon
        selection_icon = null
        ..()

obj
    MouseEntered()
        usr.client.selection_icon.loc = src
    MouseExited()
        usr.client.selection_icon.loc = null


If you are ever looking through a list of objects for a specific object, odds are that you should have that object stored in a variable somewhere.
