use the system highlight color

[Brannon]

A few minor nitpicks in version 7:

The installer with style "modern dynamic windows11" doesn't actually use the highlight color specified for the Windows theme. It always uses blue instead. It should use the system theme colors as queried from the system.

The color of the (absent) border around the license text is different from the border around the text box on the next page (that shows the selected installation folder). The license text control might also benefit from a bit of padding inside.

I have an rtf file that contains my license text. The rtf file contains no coloring information at all. When this is displayed via wine (version 11.5) on Linux with the "modern dynamic windows11" style, the license text is black on black. It seems to look okay (showing white text) on Windows.

Hi,

Thanks for the feedback. I think all of it actually applies to version 6 as well.

• A dynamic highlight color is unfortunately not supported by the VCL Styles system we use AFAIK.
• Do you have a screenshot explaining what you mean about the border colors?
• I think the padding might be controlled by the RTF, but am not sure.
• The code we use to handle RTF colors when a style is active can be found at https://github.com/jrsoftware/issrc/blob/e582551b4789b976927fa35679ffe60535a6c8d0/Components/RichEditViewer.pas#L485
  Perhaps wine does not support EM_GETOLEINTERFACE? I suppose it could fallback to our previous implementation, which simply removed all foreground coloring. Not ideal but would avoid black on black.

Greetings,
Martijn

It seems you can use StyleServices.GetSystemColor to read out the current system colors. You would then apply those to your theme or controls. There's some example here: https://support.tmssoftware.com/t/new-delphi-style-system/20774 . I haven't looked into it deeply.

About the border, I just mean that there isn't a border or it's not visible in the dark theme on the license text box.

So the RecolorAutoForegroundText method is trying to override any colors that might be included in the rich text document? Maybe it would work to strip those tags from the RTF before displaying it instead? Or maybe we just warn the user at ISS compilation time that their RTF has colors in it that might conflict with the dynamic theme?

You're probably right about EM_GETOLEINTERFACE being not fully supported on Wine. That seems scary.
