missing icons

[John W. Eaton]

There seem to be many missing icons in the GUI.  Can someone help me
understand how Qt icons are supposed to work?  For example, in the
terminal_dock_widget constructor in
libgui/src/terminal-dock-widget.cc, we currently have

  setWindowIcon (QIcon(":/actions/icons/logo.png"));

I think this is supposed to refer to the Octave logo.png file in
libgnu/src/icons/logo.png, but the terminal dock widget doesn't
display any icon for the window icon position on my system.

Similarly, the code that sets up the context menu that is defined for
the terminal window in QTerminal.h appears to add icons to the menu
but those are also not showing up on my system.

Is it just me, or is this not working properly for others as well?

What does /actions/ mean in the name that is passed to QIcon?
