Re: EOG background color ... when in fullscreen mode


Hi Felix,
... yes 'oxygen-gtk' style is already compatible with both GTK+-2.* and GTK+-3.* ... and this is how EOG 3.2.1 looks like on my Kubuntu Oneiric amd64 install : 

http://ge.tt/8nL4OyB/v/0
Talking about IMMERSIVE things ... and why I am so interested in being able of customizing the fullscreen background color to my needs ... ... ... maybe ... maybe the source of the problem is how I am using EOG. The truth is that I am not using EOG just as my Image Viewer ... but also as my 'Document' Viewer ... I will explain myself :
- I have come to the habit that ... whenever I read an interesting article on the web, a useful howto, whatever I consider very interesting and want to have a copy of it ... I take a photo of the whole web page (using Adblock plus gives you the chance of getting a very 'clean' photo) and store it for future consult or whatever. Instead of saving the web page (some files and a folder) I am interested in, having an PNG image is much more confortable ... it is easier to move between machines using Dropbox , I can even use OCR technology if I want to edit the 'document' ... that's what I do ... but ... what I mainly do with these 'documents' is reading them ... and here's where EOG comes in. EOG is so light, snappy, agile that it has become my 'document' viewer. I switched zooming for scrolling on a very deeply hidden entry on DSettings and now I can read, zoom and scroll very LONG 'documents' in a very handy fashion just moving my finger through the touchpad.
When in fullscreen mode ... where an IMMERSIVE background or a dark background may be convenient for viewing IMAGES ... it may not be so confortable for reading 'DOCUMENTS' due to the VERY high contrast between the black background and the usually white document's paper ... here's an example : 


http://ge.tt/8kuWUyB/v/0
... at the end of the day it may just be a matter of tastes ... and yes ... the problem here could be related to the fact that I am using an image viewer as a document viewer ... but ... ... ... EOG does it so well !! ... so soft ... ... the fonts' antialiasing works so smoothly ... ... and ... ... I am not asking for the moon ... just being able of changing the background color ... ... ... ... who knows ... maybe I am not the only one user in this mood ... 



... ANYWAY ...
... if you EOG guys have other priorities ... I can understand it ... so I have tried the workaround you showed me on the previous comment. 

I have added the following at the end of my ~/.config/gtk-3.0/gtk.css


EogThumbView {
background-color: white;
}
... white instead of black just for checking if it works but ... in my case the color I would like to set would be #918E7D .
Actually ~/.config/gtk-3.0/ is a symbolic link to my /usr/share/themes/oxygen-gtk/gtk-3.0 


This is how my ~/.config/gtk-3.0/gtk.css looks like :

Well ... after editing the file nothing happened ... I rebooted the laptop and ... the fullscreen background color remains black. :-(
Regarding to opening a bug in Bugzilla ... I mean ... I don't want to waste your time ... maybe it's just me giving great importance to a nonsense ... do you consider this really worth it ? 


Thanks a lot.

   Hello,

Hi Ana,



   I consider EOG such a great tool ... to the point that I am still
using it as my primary image viewer even though I migrated to KDE
some time ago.

that's always nice to hear. :)


   I always wanted to be able to modify the background color  ... when
in FULLSCREEN mode (BLACK by default on my laptop).

   These days I have had some time for gathering information to look
for a way to carry it out ... and this is what I have found ...

- In 2009 something similar was requested ( Bug 569025 ;
https://bugzilla.gnome.org/show_bug.cgi?id=569025 ) :

       At the end of the thread a responsible stated ...     “I'd
prefer to have this defined in a theme, instead of enforcing this to
eog users or adding a preferences for that. You can probably tweak
this in gtkrc file. Closing as WONTFIX. Thanks for the report anyway!”

   The argument seems reasonable ...  but ... I didn't lose my faith.

Well, this part is actually possible to do. If you are using a eog-3.x
you can add the following CSS to your GTK-3 user overrides
(~/.config/gtk-3.0/gtk.css) to paint your collection background black:

EogThumbView {
	background-color: black;
}


   I am using 'oxygen-gtk' style for gtk+ apps on KDE ... the practical
result of this setup is that widgets, COLORS, typographies on gtk+
apps are virtually identical to qt native ones.

Hmm, okay. Is this actually compatible to GTK+-3.x already or is it
still GTK+-2.x only?


   Coming back to my original itch ( being able to modify background
color of EOG when in fullscreen mode) ... according to the  previous
comment “I'd prefer to have this defined in a theme” ... all I had to
do was to define at KDE theme level the 'background color on
fullscreen mode' I wanted ... then 'oxygen-gtk' style would replicate
the settings for my EOG install in Kubuntu. But I bumped into an
strange KDE bug ...


- In 2005 it was requested having the availability to set the
background color in fullscreen mode on KDE ( Bug 101634 ;
http://bugs.kde.org/101634 ) :

    In May 2011 a responsible stated ...    “Fullscreen mode is
designed to be more IMMERSIVE than browse or view mode. This
is the reason why the background is HARDCODED TO BLACK.”

   The bug was closed as (RESOLVED ; WONT FIX)


   Sincerely ... my personal opinion is that the 'IMMERSIVE' argument
is not a good one ... not at all.


   Now I am STUCK ... at EOG they prefer the background color when in
fullscreen to be set at theme level ... and in KDE this level is
HARDCODED to black because Fullscreen mode is designed to be more
'IMMERSIVE' .

Well, "IMMERSIVE" isn't the term I'd use for it. But generally dark
backgrounds are prefered for this due to the better contrast to the
displayed image. That's also the reason why eog-3.x uses a darker theme
variant (if available).


   I don't feel brave enough myself for negotiating about 'IMMERSIVE'
issues and ... even though I understand EOG initial position is
reasonable ... I also consider that having the availability of setting
background color when in fullscreen would also be a great feature ...
that would make ALL EOG users independent from the desktop
environment ... which shouldn't be a bad thing.


   And my question ...

      ... is there any chance this additional feature could be
implemented so that EOG users outwards GNOME could face things in an
less difficult way ?


   Or at least ...

      ... anybody knows a way / trick / workaround  so that I can
customize the background color of EOG when in fullscreen mode ?    ...
maybe the 'gtkrc' way ?????

It depends a bit on the version of eog you are using. eog-2.x uses GTK
+-2.x and would require an override in a gtkrc file while eog-3.x/gtk
+-3.x can be overriden using CSS (as shown above).

The problem is that we set the background color programmatically when
entering fullscreen mode and reset it upon leaving. This makes
overriding through the theming system unavailable for this case. I
wouldn't want to add a GSettings entry for this (like the other color
settings) though as this setting would be changed by even less users.

So, all I could offer would be to improve the possibility to theme the
image view widget in fullscreen, although I have no idea about what
would be the best way to do it.

Anyway, I'd ask you to open a ticket in our Bugzilla for this request as
it makes it generally easier to track for us.

Regards,

Felix
