Here's the problem I am having in FreeRIDE (FOX 1.0): I use an
addInput to listen to a file descriptor which happens to be the STDOUT
of a remote process. I use INPUT_READ on this channel to capture the
incoming text and display it in a FXText object.
The problem I have is when the remote process generate output at full
speed, I can't get the FXText object to refresh and draw the line of
text in a continuous way instead of displaying almost everything in
one go when the remote process finally stop.
Is there a way to solve this problem? Like giving some cycles to the
"normal" update events that will refresh the FXText widget.
Any idea is welcome
Here is the piece of code that I use for monitoring the file descriptor:
def attach_stdout(fh)
getApp().addInput(fh, INPUT_READ|INPUT_EXCEPT) do |sender, sel,
ptr|
case SELTYPE(sel)
when SEL_IO_READ
begin
text = fh.sysread(100000)
print_stdout(text) # print the text in the FXText widget
rescue EOFError
detach_stdout(fh)
end
when SEL_IO_EXCEPT
puts 'onPipeExcept'
end
end
end
