One suggestion as I suspect this was unintended.
When dragging form low index to higher index the dropped index was (dest
-1) and for me should be dest idx.
if(destIndex > i) {
t.insertTab(title, null, source, destIndex - 1);
} else {
t.insertTab(title, null, source, destIndex);
}
should become:
t.insertTab(title, null, source, destIndex);
Q. How can we change the drag sensitivity or delay so that when I want to
scroll my tab list the dragged listener does not interpret this as a drag
request.
Thanks in advance.
Regards
