Re: [Discuss-gnuradio] gr-display

First, if you run the generated top_block.py you see

Traceback (most recent call last):
  File "./top_block.py", line 99, in <module>
    tb = top_block()
  File "./top_block.py", line 71, in __init__
    self.tab_grid_layout_0.addWidget(self._show_text_0_win, 1000,110)
  File 
"/usr/local/gnuradio/lib64/python2.7/site-packages/gnuradio/gr/hier_block2.py", 
line 93, in __getattr__
    return getattr(self._impl, name)
AttributeError: 'top_block_sptr' object has no attribute 'tab_grid_layout_0'

So remove remove the entry in the gui hint of gr_display.

Second, characters that can be displayed are in the range of 32 to 128 
and not between 0 and 2.

Third, you try to generate 1000 * 32000 each second. That's to much to 
display.

Set repeat of in you random source and min and max appropriate and 
you'll see the generated values will be displayed.
