Context menus

When you right-click on your Linux desktop you get a context menu displayed. It looks like this:

How to edit it highly depends on your desktop environment.

See /usr/share/kde4/services/plasma-containmentactions-contextmenu.desktop

tweedleburg:~/.kde4/share/config # diff plasma-desktop-appletsrc~ plasma-desktop-appletsrc
3d2
< wheel:Vertical;NoModifier=switchdesktop
tweedleburg:~/.kde4/share/config # cd /usr/share/kde4/services
tweedleburg:/usr/share/kde4/services # grep -ir "switchdesktop" *
plasma-containmentactions-switchdesktop.desktop:X-KDE-Library=plasma_containmentactions_switchdesktop
plasma-containmentactions-switchdesktop.desktop:X-KDE-PluginInfo-Name=switchdesktop
tweedleburg:/usr/share/kde4/services # grep -ir "contextmenu" *
plasma-containmentactions-contextmenu.desktop:X-KDE-Library=plasma_containmentactions_contextmenu
plasma-containmentactions-contextmenu.desktop:X-KDE-PluginInfo-Name=contextmenu

Questions

• why can't I

plasmoidviewer contextmenu

while i can use the contextmenu in .kde4/share/config/plasma-desktop-appletsrc

• why can't I use charselect in .kde4/share/config/plasma-desktop-appletsrc

while I can

plasmoidviewer charselect

• seems this is determined by the type. One has

ServiceTypes=Plasma/ContainmentActions

the other

ServiceTypes=Plasma/Applet

• hm... do ContainmentActions need an init function to work? And in case of javascript Applets, just the javascript code is executed and an init function is not needed?
