Welcome

About forcing the applications to use a diferent icon set.
This is possible with Gtk2 apps.
Need to create a file /home/USERNAME/.themes/medit.gtkrc
#To set the Gtk theme
include "/usr/share/themes/dorian-theme-3.12/gtk-2.0/gtkrc"
#To set the icon theme
gtk-icon-theme-name = "LinuxLex-8"
Then running the gtk2 app like medit with a prefix launches app with different theme and icon set.
GTK2_RC_FILES=/home/USERNAME/.themes/medit.gtkrc medit
To launch Gtk3+ app with a different theme:
GTK_THEME="dorian-theme-3.12" iceweasel
That would probably need to be wrapped for the desktop files.
/bin/sh -c 'GTK_THEME="dorian-theme-3.12" iceweasel'
/bin/sh -c 'GTK_THEME="dorian-theme-3.12" /usr/local/bin/menu.py'
Took me while to figure it out that the only way to force icons on a certain gtk3 app is to edit the theme settings.ini file and define which icon set will that theme use.
In my case /usr/share/themes/dorian-theme-3.12/settings.ini
adding next line to the file end, changes the icons for that theme.
gtk-icon-theme-name = HumanXMint
Also the font for that theme can be changed if needed.
http://fluxbox-wiki.org/category/howtos/en/Using_gtk_themes.htmlNow when I run iceweasel I have a different theme icons and font size applied on the browser.
GTK_THEME="dorian-theme-3.12" launch iceweasel
The icon in tint2 is also from a custom icon set. That can be changed because open source is awesome.
