Windows 10 Screen Scaling with GF/ST

We are using GF/ST to provide a graphical interface for our users.

We are having troubles on Windows Screen, when Scaling is != 100%. X & Y coordinates of mouse operations are not correct (If I manually factor in the screen scaling, everything seems to work again ;-) ).

I remember reading something about the screen DPI scaling that could be used in order to set the correct factors for GF/ST. Does anyone have a tip on where to look?

Thanks

Thomas

Re: Windows 10 Screen Scaling with GF/ST

Hi Thomas,

Could you please tell which exact version of VAST and Windows are you using?

Also...sorry for the newbie question but what is GF/ST?

Thanks,

Re: Windows 10 Screen Scaling with GF/ST

Hi Mariano

We are using VAST 10.0.1 however the code has its origins in VA/Smalltalk 8.2 (And we did quite some "special" stuff in GF/ST ;-))

Re: Windows 10 Screen Scaling with GF/ST

I still need to know which Windows version and what it is "GF/ST"

Re: Windows 10 Screen Scaling with GF/ST

I thought, it is a problem from our migrated code but the GF/ST demos have the same problem....

I am using a 4K graphics card with 4K monitor with 200% scaling running Windows 10 (20H2).

In VAST 10.0.1 32-bit load the config maps.

GF/ST IBM/ST - Runtime

GF/ST IBM/ST

GF/ST Demo IBM/ST

Then Start

GFDemo->GFDemoLauncher

Start the "Drawing" Demo and the connectors are not aligned and it is easy to get draw errors - see the attached PNG

Re: Windows 10 Screen Scaling with GF/ST

Hi Thomas,

Thanks for your report. I was able to reproduce it. I will create a support case on your behalf with this information and we will allocate engineering time to fix it.

Best,
