Re: [Discuss-gnuradio] Help with wx-gui, window size error

[Thilina Mallawa Arachchi]

Hi Martin,

I am feeding in IQ samples at a sample rate supported by the SDR via the IShorttoComplex block.

I cannot use the QT GUI sinks, the blocks are not visible to me in my gnuradio install.

On a side not I can use the WX-GUI Waterfall Plot, so not all my WX-GUI blocks are 'broken'

Kind Regards,

Thil

Is this a know bug? whats the best way to fix it? I am new to gnuradio.

I'm running gnuradio 3.7.3-4

Kind Regards,

Thil
