GRC Qt
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.
Preferences
Go to File->Preferences to open the preferences menu.
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!
