Re: [Interest] Weird sizing in Qt Designer 5.12.0 with hi-res screen

2019-01-23 Thread Tony Rietwyk 

Hi Dmitriy,

The software is at https://www.risingsoftware.com/ and covers both 
aspects that you mention.  It can generate progressions, or use supplied 
set pieces and notation.  The student can either annotate the notation 
with the chord symbols - or even fill in the voices as well.  The 
student may or may not actually hear the progression.  It's wonderful 
software to work on - sure beats boring business crap!


Regards, Tony

Off topic but out of curiosity: what is the software you have on your 
screenshot? A harmony learning helper or some kind of a harmony 
progression generator?

Hi Everybody,

I have recently installed a hi-res screen 3840 x 2160 @ 150%
scaling on
my Windows 10 machine.

The attached screen capture has Qt Designer on the right of the
actual
running dialog, with a screen ruler on top of the designer. You
can see
the following:

- Designer is showing the form at double the size it should be
(1200 for
a form at minimum size 600 high).

- Even the grid spacing has been stretched.

- We do not set any of the newer high-res related settings at run
time,
so the dialog appears at the expected 600 pixels high. Instead we use
style sheets to adjust fonts, images, etc.

Why is Designer doing this?  Where is it getting the factor of 2
from?
How do I get it to display the form at the correct size?

Regards, Tony

I'm not sure if this explains the problem you report, but we've found that
Qt does not fully support scale factors that are not a multiple of 100%. If
you change your scale factor to 200% (you may also need to log out/in
and/or reboot) you might find that you get the correct behavior.

On a related note, we've also sometimes found that Qt (and even other
non-Qt applications) misbehave on a system with multiple displays that have
different scale factors or on a mixed DPI environment (eg. one regular DPI,
one high DPI). The situation here has improved since Qt first started
supporting high DPI displays.
