Themes

Hello guys.

I am trying to use a dark theme for the editor. I've chosen "solarized-dark". But I would like to change a few things, so I tried to edit the theme. When I click the button to create/edit personalized color scheme, Calibre throws an error msg. This is the msg:

Righ now I don't know what I will find inside this option, because it fails to activate. Is it possible to choose a color for the selected line, just like on the default theme? All the other themes besides default lacks this functionality. When using "Solarized dark", it does change the color of the element you are inside (for instance, it will change the color o the <p> tag when you click that paragraph). But, the actual line is not highlighted like on the default theme.

that looks like abug in the calibre translation, try temporarily changing your calibre interface language to english and see if the error goes away

ohand all themes are capable of all features, you just need to define a different color for the feature you want so that it shows up.

Thanks, Kovid. It worked!

By the way, if you want, I could help translating Calibre to Brazilian Portuguese. The software is already translated, but there are two bugs that I can recall at the moment: this one you just pointed out and another one on the "Smart comment" menu item (looks like the h3 closing tag is falty), also on the Editor.

I think the Manual is what needs more work, since there are a lot of sections without translation.

Anyway, I would need some instructions, since I don't know anything about the translating process.

Once I changed it to English, I could see all the options there. Now it looks just the way I wanted. Thanks!

Tweaking the translation did the trick. Now, the Theme Editing GUI is working fine. Thank you for the tip!

Now that I know how translating works, I'll keep helping translate other sections.

Just one last comment...

I've noticed a particular behavior: when I launch the Editor and go directly (whitout openning any file) to Theme settings, the "SpellError" rules do not apply to the live panel on the right. On the other hand, if a file is opened on the Editor, then the rules apply correctly. Is this because the dictionaries are not loaded before an actual file is opened?

yeah without any book open, the spelling system is not intialized.
