I’ve done some more experiments, and it seems that cdk functions always take an 
absolute coordinate (relative to the root full-screen window) no matter what 
screen I passed to them. So in order to put some widget at the top-left corner 
of a sub-screen I cannot just use (0,0), but have to use (x, y) instead, where 
x, y is the location of the sub-screen. Widgets that are placed outside the 
region of the sub-screen will be moved into the subscreen according to some 
rule, it seems to me.

Is that how cdk functions supposed to behave?
