Got a question...
I'm trying to gather the output of a system command and display it in a browser object, however, if the command takes a while the window will not appear (with the browser object in it) until the command is complete.. even-though the command is producing output. Actually the output window will start to appear, depending on the command, but won't fully paint. For example doing a ping or traceroute and showing the output as it is produced. Is there a better/recommended way to do this:

function execute_cmd()
local fh = io.popen( cmd );
if ( fh ) then
output_window:show();
while true do
local data = fh:read( "*l" );
if data == nil then break end
br_output:add( data );
output_window:redraw();
br_output:redraw();
end
fh:close();
end
end

Thanks,
-Craig
