Re: Cannot resize GRC window panels

[Ryan Volz]

Hi,

And now the conclusion to this riveting saga...

Further investigation has revealed that the problem is that the drag 
indicator icons were not being found with the conda xorg-libxcursor 
package installed. You can still actually click and drag to resize the 
panel boundaries, there's just no visual indication. This happens 
because installing that package causes X11 to look for cursors in the 
conda prefix but not the system prefix, and unless you're using the 
Adwaita theme it won't find them.

You can set the XCURSOR_PATH environment variable to point to your 
system cursor installation (probably /usr/share/icons) to get things 
working properly again:

export XCURSOR_PATH=/usr/share/icons:/usr/share/pixmaps
gnuradio-companion

I also have a fix to the xorg-libxcursor package so that it will fall 
back to the system directories when looking for cursors. That should be 
rolled out soon so that the environment variable workaround is not 
necessary after an upgrade.

Cheers,
Ryan
