how to revert to light mode in 4.0?

masp · 10-07-2019, 12:49 AM

Hi: just got 4.0 working and finding the "dark mode" a bit hard to read: is there an option to switch back to "light mode"? (dark text on light background)

Thanks!

I assume you are on macOS? Change your system appearance to light and calibre (or more precisely Qt) will pick it up automatically after a restart.

Yes I am (mac os). I don't want to turn off dark mode system-wide but I'm finding calibre's text colors (especially blue hyperlinks) hard to read against the dark background (and also black text against a dark green background), so I was hoping that calibre would allow me to override the system setting and use a light background: not possible?

No not possible. But you can change the blue color in Preferences->Look & feel->Book details and the dark green in the edit metadata dialog box has become a baorder not a background in the next release

Thanks for the pointers! I do have a strong preference for the dark-on-light (rather than light-on-dark) look for viewing databases like calibre, despite also preferring a system-wide "dark mode" for UI elements in general, so if it's possible to add an option to switch to the (pre-4.0) dark-on-light theme, that would be even better

This is not really something calibre does, it's automatic at the toolkit (Qt) level.

masp · 10-07-2019, 09:52 PM

Wow, I'm surprised that QT cedes so much control over the UI to the OS! Thanks for the clarification!

FYI, I just discovered how to disable dark mode at the app level:

Quote:

defaults write net.kovidgoyal.calibre NSRequiresAquaSystemAppearance -bool yes

or revert to default with:

Quote:

defaults delete net.kovidgoyal.calibre NSRequiresAquaSystemAppearance

Tested and works: I'm delighted!

Cool just dont later forget you did that and complain dark mode is not working

HogDrvr · 10-08-2019, 08:06 AM

Can somebody tell me exactly where and what I should alter to change the dark blue text while in dark mode? I assume it goes somewhere in the following:

Code:

table.fields {
    margin-bottom: 0;
    padding-bottom: 0;
}

table.fields td {
    vertical-align: top
}

table.fields td.title {
    font-weight: bold
}

kovidgoyal · 10-08-2019, 08:11 AM

Just add

Code:

a { color: yellow }

at the top change the color to whatever yo uwant

HogDrvr · 10-08-2019, 08:58 AM

I've tried putting { color: yellow } in every possible field including at the very top. I get no results and still can't read the text. I know it should only go in once and I'll delete all the extras as soon as I figure out just where the code should go.

kovidgoyal · 10-08-2019, 09:02 AM

You missed the "a" and put it only at the top

HogDrvr · 10-08-2019, 09:06 AM

Beautiful, thanks. I've got it working now.

In my humble defense, I read that as put a "block of code" instead of "a block of code". I read the "a" as an article in the sentence.

Same complaint. This fix worked for me. Thanks.
