Wrong icon for search in Software Center

As shown in this screenshot, the search icon USC uses is different from the one Nautilus uses, but it's the same as the one Firefox uses.

I don't understand what's going on here. Maybe Firefox and USC are using a non-symbolic icon, while Nautilus is using a symbolic variant? I think a search icon inside a text field should always be a symbolic one.

As for why it's on the left, the Clear button is on the right. In Firefox and Nautilus, the search icon is something you click to perform the search. In USC, we use a live search instead, so putting it on the right would be misleading.

nb. to Self blue icon (Firefox, USC):

  /usr/share/icons/gnome/22x22/actions/edit-find.png

Symbolic flat icon (Nautilus screenshot + Toolbars):

  /usr/share/icons/gnome/scalable/actions/edit-find-symbolic.svg

So, the USC search widget just needs to use edit-find-symbolic rather than edit-find. Thanks Paul.

mpt: to pre-empt your next question, the clear icon used in the Shotwell search field is:

  /usr/share/icons/gnome/scalable/actions/edit-clear-symbolic.svg

nb. to self; the QML version's search box is hard-coded:

  softwarecenter/ui/gtk3/widgets/qml/SearchBox.qml:
    FocusScope::searchbox:
      source: "file:///usr/share/icons/Humanity/actions/16/edit-find.svg"
      source: "file:///usr/share/icons/Humanity/actions/16/edit-clear.svg"

Gtk3 search box uses Gtk+ STOCK_* enums:

  softwarecenter/ui/gtk3/widgets/searchentry.py:
    Gtk.Entry::SearchEntry::__init__():
      self.set_icon_from_stock(Gtk.EntryIconPosition.PRIMARY, Gtk.STOCK_FIND)
    Gtk.Entry::SearchEntry::_check_style():
      self.set_icon_from_stock(Gtk.EntryIconPosition.SECONDARY, Gtk.STOCK_CLEAR)

I've updated s-c to use the 'edit-find-symbolic' icon in the search box. As for the clear icon I've left that as non-symbolic in the mean time as the symbolic variant looks fairly dark and bulky - but that's just one opinion, so if you want the clear icon to use the symbolic variant too just give a shout and I'll change that too.

Looks very nice indeed. Thank you Kiwinote! Now merged to trunk.

This bug was fixed in the package software-center - 4.1.22
