In https://bugs.eclipse.org/bugs/show_bug.cgi?id=532185 we enhanced the eclipse help system and the help documents so that the prefers-color-scheme media query (see https://drafts.csswg.org/mediaqueries-5/#prefers-color-scheme ) is used there. With this the help is displayed in dark mode when the OS-level settings are set to "dark mode". When the help is displayed in the integrated help view the SWT browser widget is used. In this case the OS-level (or even eclipse "appearance" preferences") don't have an effect on that. Can this be changed so that the embedded browser also considers these settings?
Do you have an example snippet or use case that shows this bug? I.e. some place where the browser isn't properly themed because of this bug?
This causes a problem for Eclipse Memory Analyzer. The tool builds HTML reports which it displays using the SWT browser. On Windows the SWT internal browser does not handle the CSS: @media screen and (prefers-color-scheme: dark) { nor does it handle: img { filter: invert(100%) hue-rotate(180deg); } The first is useful to automatically change the style sheet. The second is a neat way of fixing coloured charts - white goes to black, black to white, and with the hue rotate dark blue goes to light blue and vice versa etc., so charts look normal. I can work around the first by copying a different style sheet when in dark mode. I don't think I can fix the second without having new image files. See bug 567533
I think this is a Windows problem with the internal "ie" browser as it works for Memory Analyzer based off 2020-03 running on Ubuntu (via Docker). If this is confirmed we could update the Hardware fields for this bug.
