| Re: [platform-dev] Scaling of Self-Hosted Eclipse Applications on Windows 10 |
Rolf,
The issue of SWT lagging behind the evolving native graphics support is has been highlighted by the planning council as an issue of high priority.

Thanks for pointing me at this bug! After some searching based on the information you provided in that bug I stumbled on this posting with a solution:
https://superuser.com/questions/988379/how-do-i-run-java-apps-upscaled-on-a-high-dpi-display
I.e., change javaw.exe like this to let the system do the
scaling.

Ed
Hi Ed,
This is most likely caused by Bug 572262, the HiDPI settings are not enabled consistently in windows. There is a difference when launching with the Eclipse executable or with the Java executable.
It would be really helpful if the Windows platform would get some more attention, it seems that quality is slowly fading.
Best Regards,Rolf

_______________________________________________Hi,
I'm not sure if someone else has run into the following problem and maybe has a solution...
I have a new computer with Windows 10 with 3 ultra HD monitors, each with the same resolution but with different physical sizes. On Windows 10 you can set a scale factor separately for each monitor such that as you move any application window from one monitor to another, the fonts and graphics automatically scale as specified. As such, you can see the size "jump" as you move a window more than 1/2 way onto a given monitor. This way everything stays at a readable/usable size on each monitor. This all works well with an Eclipse application too, except for a self-hosted launched application where the menus and title change sizes but other parts don't; even the scrollbars paint funny with "cheese" to the left of the vertical scroll bar (as seen in the properties view of the final image below).
Here are two screen captures from different monitors for a normal application. Note how the menu font size and other font sizes are relatively the same with just the entire image scaled:
But dragging a self-host launched IDE onto a physically smaller monitor (smaller than the primary monitor) looks like this, where you can see the menu fonts are much bigger than the other fonts and graphics:
This didn't happen when I had older target platforms (two years old) from which I launched...
Does anyone have a clue on some magical thing (system property or command line argument?) I need to make the self-hosted launch scale the way every other application scales automatically?
Regards,
Ed
