Button with SWT.ARROW style is not styled correctly in dark theme

[dhendriks]

A Button with SWT.PUSH style is correctly styled with the dark theme. If I use the SWT.ARROW style however, it does not get styled:

I use these in an Eclipse EditorPart. I create them as follows:

Button push = new Button(comp, SWT.PUSH);
Button arrow = new Button(comp, SWT.ARROW | SWT.DOWN);

I don't do anything special with them regarding styling. I just set Eclipse to use its built-in dark theme. I use Eclipse 2022-06 on Windows.

Is this an SWT issue? Or is some other part of the Eclipse Platform responsible for this problem?

This looks like bug in SWT windows port. Ideally one should provide a pure SWT snippet demonstrating the issue to ease further development.

How can I create a pure SWT snippet that uses the OS dark theme? My Windows is set to a dark theme. I tried using the following, but they don't seem to have an affect:

-Dorg.eclipse.swt.display.useSystemTheme=true
-Dorg.eclipse.swt.internal.win32.enableCustomDarkTheme=true

Unfortunately I can't help much with Windows specific things. Eclipse theming engine does a lot of setForeground/Background with hardcoded colors.
Maybe @niraj-modi or @sravanlakkimsetti can guide you about windows specifics.
