[Discuss-gnuradio] GRC: File/Path browser in QT or WX gui ?

[M Dammer]

I am looking for a standard file browser widget for a QT or Wx based
GUI. You browse the filesystem and the moment you click "o.k." the
choosen path is put into a variable that can be used within your
flowgraph. Is this possible ? Currently the only option I see is to set
the filename/path within the flowgraph (e.g. WAV sinks/sources).
