[PATCH weston 4/9] shell: Implement menu for window list items
Scott Moreau
oreaus at gmail.com
Thu Mar 7 20:47:13 PST 2013
Right-click dropdown menu for window list items. This patch introduces a simple
minimize feature. The surface is removed from the layer list on minimize and
re-added on unminimize. The close item sends the client a SIGTERM signal.
