How to get the zoom factor of the display?

[Zinn]

How to get in a BlackBox program the number of pixel on the display and which zoom factor is set?

Since Ubuntu 16.04 the status line at bottom is not display complete by using a zoom factor in the operating system.

Further I have the problem with subsystem Desktop by moving to another machine. The windows have the wrong size after restore the saved desktop, because they have set different zoom factors.

How to get in a BlackBox program ... which zoom factor is set?

If I understand the question:

Ports.port.unit
or
Ports.frame.unit
or
HostWindows.unit.

Also HostWindows.mainW, mainH might relate to the other part of your question.


PS - Is this question better on the other forum?
