Hi,
I just wanted to ask if anybody else on the list sees some strange
behavior
with waterfallsink2.py.
For example when I execute usrp_fft.py with the -W option I do not get
a waterfall graph as expected but instead of having the spectra moving
down slowly the actual spectrum is drawn over the whole height of the
graph.
I tried to track down the problem and it appears that the bitmap is
copied
correctly to shift it one down but later gets overwritten (see [1])
because
the height value of 1 in the method dc1.DrawRectangle() is somehow too
small. If I set it to 2, i.e. dc1.DrawRectangle(x_pos*p_width, 0,
p_width,
2),
it works.
I suppose it’s a problem in wxpython or even wxwidgets and I am just
curious if it is specific on my install or if the other Gutsy users find
the
same behavior.
The computer runs an Ubuntu Gutsy and the version of wxwidgets is 2.8.4.
I use the latest gnuradio from the trunk.
Best regards,
Tobias
ps. In waterfallsink2.py in the class waterfall_window
make_colormap(self)
is defined twice. [2]
