Ongoing problems with lack of icon control [message #1871856]

Having invested in a 3840 x 2160p resolution monitor I have been fighting to get ALL applications displaying at the same higher resolution in a readable manner. The first hurdle was getting SUSE linux to display the cursor at the right size independent of the 'widgets' library being used and that requires hand editing ini files so that the icon/cursor setting is 48. But that does not fix the eclipse desktop toolbar ...
I've tried editing the '-Dswt.autoScale=150 ' but anything other than 100 messes up the rest of the window. The 'windows fix' is obviously not applicable. I've not as yet found just where the bulk of the icons are stored? They are not as directed in other posts although I have now found the eclipse-icon-enlarger on github. Not as yet resorted to that as I would prefer to know just where the icons are to back them up first! Does it still work 10 years on and why is it STILL necessary?
Other fixes say select 'large icons' which I presume at some time in the past WAS an option on some previous builds? Again it is not an option today, but it seems to me that it is more relevant given the much higher resolution displays we have NOW.
In the short term just switching off the tool bar altogether seems the best option, but that still leaves a few icons elsewhere in the display area. At least here in the forum edit window one CAN zoom and the formatting tools icons zoom with it, but this problem is not just restricted to eclipse, it seems to be generic to current display tools?

It's probably better to ask here.

https://github.com/eclipse-platform/eclipse.platform.swt/discussions

There is quite a bit of work going on for HDPI support, but I think it was mostly focused on Windows. Be sure to provide details about which version of Eclipse you are using.

Have you tried '-Dswt.autoScale=200`, or other settings that might have been shown in https://eclipse.dev/eclipse/news/4.6/platform.php#swt-autoscale-tweaks ?

"Have you tried '-Dswt.autoScale=200`,"

As I said ... ANY setting other than 100 results in the whole page being corrupted.

I've got a few more tools set up on this brand new machine and I suspect this is a 'platform' problem? I'm running a package called PDFArranger which has the same problem on it's window top bar but that package was fine on the previous set of hardware on the same monitor.

(There are reasons beyond my control why I do not have access to the older machine :( )

Problems can and will only be fixed if the developers are made aware of the problem which is why I provided a GitHub link where you can ask questions and an issue can be created if something is truly broken.

There has been no response on github. But then it was only 3 days ago.
I have not been sitting on my hands and have been trying to establish JUST where the problem is. I think I am now in the right area and assuming eclipse is using QT5 then https://doc.qt.io/qt-5/highdpi.html is the relevant base to work from. This identifies that iOS and Windows have options to change the way HighRes scaling happens, but no mention of Linux.
Following your suggestion I DID go back and try it again, but without success. In addition I have now noticed other places where 16x16 icons are displayed. Is that 'truly broken' behaviour? Probably not, but the size of toolbar icons on eclipse has reports going back at least 13 years. That a 'fix' is platform dependent I personally think is a fault in QT which is supposed to provided a platform agnostic base? That distributions such as openSUSE can't update the QT settings when loading new themes is another 'bug' that requires manual editing of the relevant setting file. That eclipse.ini has in the past been hand modified to provide a fix is not a solution to the base problem ... which in my opinion is not a bug IN eclipse, but rather in it's choice of interface?
Once I get a server back up again I will start documenting this for reference.

I see this:

https://github.com/eclipse-platform/eclipse.platform.swt/discussions/1534

Yes, apparently not so many people consider answering questions a high priority. :-(

If I had the problem, and no one answered my question, I would download the latest 4.34 I-Build:

https://download.eclipse.org/eclipse/downloads/

Currently

https://download.eclipse.org/eclipse/downloads/drops4/I20241016-2000/

So probably this for SDK IDE for linux:

https://download.eclipse.org/eclipse/downloads/drops4/I20241016-2000/download.php?dropFile=eclipse-SDK-I20241016-2000-linux-gtk-x86_64.tar.gz

And I'd try to reproduce the problem. Then I would open an issue at the following place with screen captures of what I am seeing and what I am trying that looks completely wrong:

https://github.com/eclipse-platform/eclipse.platform.swt/issues/

It's really easy to copy an image and paste it directly into the browser area where you author the issue markdown.

I would include all the details about my operating system and version as well as my Java version. No guarantees that people will help, but I'd do it anyway.
