[Gambas-user] kdesu vs gksu

[Steven James Drinnan]

For me I would use neither, it would rely on those packages being
available. In Fedora it uses its own graphical system - sorry can tell
you the name its linked directly to the authentication system. As such
those packages are nowhere to be seen.

Instead let your package do the checking using shell. 

There some examples around. If you need I can give you one that you can
add in to the sample given by Jose J. Rodriguez.

Steven.
