1. Download and install a dark theme for your distribution. Beware
there are many broken and outdated themes for gtk2. So you have to try
a few. For example NOX.
2. Start the IDE with:
GTK2_RC_FILES=/usr/share/themes/NOX/gtk-2.0/gtkrc ./lazarus
3. Set the source editor colors:
 Tools / Options / Display / Editor / Display / Colors
3.1 Change Default to Twilight.

I give up!  After looking at most of the links in this thread, I can not 
get the Lazarus IDE to use anything other than the default theme ('black 
on white - with language highlighting).  I would really like to use a 
dark theme (white on black or gray - again with language highlighting).


I normally start lazarus from a .desktop file, but even dropping back to 
the command line (with --pcp= ... ) nothing I have done changes the theme.


Could someone give me a command line that I could adapt to produce a 
dark theme?


Thanks,

For gtk2:
GTK2_RC_FILES=/usr/share/themes/HighContrast/gtk-2.0/gtkrc ./project1

From what I remember, LCL-GTK3 is not stable yet (I might be wrong though).

Thanks for your answers!

I reverted XFCE color scheme dark to normal ... no trouble any more :-)

Example:

TStringGrid.AlternateColor := clMoneygreen -> unreadable with a dark 
color scheme -> white font on white background,

The issue here is that the native theming clashes with some built in 
Lazarus settings. E.g. if you look at the link I posted that showcases 
SynEdit color schemes you will notice there is an image asset that 
does not blend in well with dark backgrounds.


These issues are typical, but they mean Lazarus does not currently 
support a native look and feel.


I don't doubt you are relaying the developer's statements accurately, 
but this probably needs to be looked at again.


Integrated theming is a good idea because unless all assets are 
obtained from the windowing toolkit then there is no way to know they 
will mesh well with a given color scheme. The theming support could be 
very minimal, and might amount to a few sets of bitmap assets and a 
review of existing UI code to ensure there are no hardcoded settings.



OP, if you could supply screenshots it would be appreciated.

Respectfully,

Hello again, very sorry for the three posts. It is the case I am not very

I realize now you were asking to disable theming in Lazarus. That answer is
related to the contents of my other posts, but for GTK you may use the
environment variable GTK_THEME:
https://developer.gnome.org/gtk3/stable/gtk-running.html.

GTK_THEME=theme:variant

If you have some time I would invite you to comment on the forum as it is
more active. It would be nice to see pictures of the interface quirks you
take exception to.

Cheers,

Unfortunately the Lazarus developers will disagree with you. They want 
"native look and feel" at all costs. So individual application theming 
is not on their priority list. I've asked for this since 2006.

Theming is typically handled by your toolkit. For GTK, you will need to
modify files in a location like "~/.themes" or "~/.gtkrc-2."

E.g. https://developer.gnome.org/gtk3/stable/theming.html and
https://wiki.archlinux.org/index.php/GTK%2B#Configuration.

Theming can also be handled by your application. The best support for
theming tends to be implemented in this way. Unfortunately from a user's
standpoint this means each program must be customized separately. On the
other hand, toolkit wide theming support tends to not be very good. Form
components (like a SynEdit) may be drawn with colors not taken from the
toolkit's configuration.

Theming support for Lazarus might be a tall order but I think it would be
worth it. See Visual Studio's dark theme, for example.
