Detailed Description

A graphical sink to display freq, spec, time, and const plots.

This is a QT-based graphical sink the takes a complex stream and plots it. The default action is to plot the signal as a PSD (FFT), spectrogram (waterfall), time domain I&Q, and constellation (I vs. Q) plots. The plots may be turned off by setting the appropriate boolean value in the constructor to False.

void qtgui_sink_c::exec_

(

)

int qtgui_sink_c::general_work	(	int	noutput_items,
		gr_vector_int &	ninput_items,
		gr_vector_const_void_star &	input_items,
		gr_vector_void_star &	output_items
	)		[virtual]

compute output items from input items

Parameters:

noutput_items	number of output items to write on each output stream
ninput_items	number of input items available on each input stream
input_items	vector of pointers to the input items, one entry per input stream
output_items	vector of pointers to the output items, one entry per output stream

Returns:

number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items

general_work must call consume or consume_each to indicate how many items were consumed on each input stream.

Reimplemented from gr_block.
