GRC Qt

GRC Qt (November 2023)

GRC Qt is a work-in-progress port of GRC from Gtk to Qt. GRC Qt aims to provide better cross-platform support, both across different OSes, but also across different versions of Qt/PyQt (PyQt and PySide, version 5 and 6). GRC Qt can be tried out at https://github.com/gnuradio/gnuradio/tree/feature-grc-qt.

New features

Example integration

Go to File->Examples to open the example browser. You can also open a block's properties dialog (double-click) and click the Examples tab to see which examples contain the block.

OOT browser

You can find the OOT browser at Tools->OOT Module Browser. It lists the installed OOTs and displays information about it from MANIFEST.md.

Undo stack

GRC Qt uses Qt's Undo framework, which comes with a built-in Undo stack viewer. You can find it at Edit->Undo stack.

Log file

GRC Qt writes logs (levels INFO and higher) to ~/.gnuradio/grc.log by default. Run GRC with --log debug to enable DEBUG level log messages too.

GUI testing

The file grc/tests/test_qtbot.py uses Pytest-qt and PyAutoGUI to test various GUI features. Warning: The script will use your mouse and keyboard for ~30 seconds!

Automatic block wiki loading

When clicking a block (either in the flowgraph canvas or in the block library to the left), the wiki tab to the right will automatically load the page from wiki.gnuradio.org corresponding to the block.
