Function setName

pj_plotting/widget/src/TabbedPlotWidget.cpp:91–129

Small private widget for one tab in the strip. Holds a name label plus a close button. Double-clicking flips the label out for an in-place QLineEdit; pressing Enter commits the rename, Escape or loss of focus reverts to the previous name.
