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

[Marcus Leech]

Just a note that the file-sink block takes a runtime-settable parameter for the file name.  In GRC, make this a variable, and link it to a text entry field, and Bob's your uncle.  This doesn't have the "file browser" aspects, but it achieves a big part of the goal.

You could have a text box with a file open dialog, and the callback would lock/stop the flowgraph, give the returned file path string to a file_source block, and then unlock/start the flowgraph.

I was thinking about people who just load a flowgraph and start it. In this case it would be very convenient to have all parameters that need adjusting (including filepath) in the GUI.
