Subject: [Cs-dev] dispfft and
QuteCsound
Andres,
I have been looking at this issue and I reckon it's something
you need to address in your client code.
Basically, it looks like no matter which fft graph you have
displayed, the widget will attempt to redraw the last one
that a Csound instrument asked for.
The opcode dispfft calls display() which in its turn
calls csoundDrawGraphCallback_(). This appears to be trying
to redraw everything, not only the displayed graph. Then
we get the last graph on the screen, not the one we selected.
If the two opcodes have different display intervals, then there is
alternation of graphs, if you select one that is not the last
being drawn.
This issue appears to be there on FLTK as well. I will investigate
further.
Regards
Victor
