This is NOT wishlist, this is a bug!
But the bug is not about append/prepend behavior: path must be
appended, like it is now, and NOT prepended. If it was prepended, the
apps' theme_path would always be picked first, and any user theme would
be ignored. So prepending would prevent themability.
The REAL bug is what evelio said in comment #1: app-indicator searches
for alternate icon names before trying an exact match in other themes
(including apps "theme_path"). THAT is what prevents an app from
changing icons.
A common scenario:
- temperature monitor 'myapp' app has several status-like icons as
myapp-{normal,hot,cool,error}.png
- they are in "/usr/share/myapp" , and app sets that when calling
AppIndicator3.Indicator.new_with_path()
- app also installs a desktop file and an icon (for dash, launcher, autostart)
in /usr/share/icons/hicolor/48x48/apps/myapp.png
- at run time, eventually app tries to set_icon('myapp-hot')
FAIL!
It can't! AppIndicator icon is locked to hicolor/myapp (the 'main'
icon), because libappindicator thinks 'myapp' is acceptable and it won't
even *try* to look for <theme_path>/myapp-hot
This is a BUG, *not* a Wishlist
A workaround is to rename the apps' "main" icon to 'myapp-icon' (which
is quite silly), or install the status icons along with main one
(polluting the themes and defeating the whole point of
new_with_path(,,,theme_path). And pray there is no similar-named icons
in other packages/themes. And not using stock icons as OP wanted.
A proper solution is not to prepend theme_path (it would work, but
defeats themability), but to first try *exact* icon name matches in all
themes BEFORE it tries this "smart" similarity matching.
Any chance of this happening?
** Summary changed:
- Appindicators should prepend app specific icon paths instead of append
+ Icon name search should try exact match in all themes before trying similar
icon names
** Also affects: libappindicator (Ubuntu)
