How to change attributes value when i move(change position) point? I don't found some information about this. Sorry for my english.
I solved this problem as follows:
I added new another field attributes, for example,
orig_coord = concat($x,' ',$y)
and in color rule i added this
if("orig_coord" = concat($x,' ',$y),color_rgb(0,0,0),color_rgb(0,255,50))
So I see the color of some of the objects changed their position in the process of moving.
Again sorry for my english.
