Unfortunately I deleted by mistake the Dolphin widget (icon?) which normally shows up in the system panel (?) in the lower left corner of the display (KDE4).
I tried to use the “Add Widgets…” function of the right mouse button menu “Panel Options”, but the list of widgets does not show a Dolphin entry nor does it allow for adding a generic one…
Any link or immediate help is appreciated very much!
klick on the kicker icon, go to System, File Manager and grab the Dolphin icon with the left mouse button pressed. Now drag it to the panel. It’s kind of tricky, but works.
