[Discuss-gnuradio] How to resize qtgui spectrum display widget (qtgui::sink_c)

[Adrian Musceac]

Hello,

I'm trying to get the qtgui sink_c widget to display with a custom
size based on window coordinates. I am calling
fft_gui->qwidget()->resize(700,350) but the only thing that gets
resized is the parent widget (returned by qwidget() ) which holds the
FFT and waterfall. Unfortunately the FFT widget gets clipped and
displayed with an incorrect size making it useless.
Is there any way to control the FFT widget directly or get it to
automatically follow the size of the parent widget?

Attaching screenshot for reference.

Thanks,
Adrian
