Thanks!
Moh, it's possible to change selection with keyboard by adding this:
function OnWndAboutEvent_LstViewSelStateChanged(PlusWnd, ControlId, ItemIdx, SelectedState) {
if(ItemIdx === -1){ return false; }
if(SelectedState==true){
Pid = PlusWnd.LstView_GetItemText(ControlId, ItemIdx, 1);
PlusWnd.ImageElmt_SetImageFile('avatar', '\\'+Pid);
}
}
