I have a graphical console widget that receives output from an interpreter. Unfortunately the console is not fast enough to paint the output in real-time. So I had to implement a buffer(FIFO Thread Safe Queue) that delayed the writes to the console by 5ms. So when normally a loop of 1000 prints would be done in less than 1 ms, it would take 5000ms to print everything.
Sequence diagram for the buffer:
writeLine:Write output from the interpreter to the buffer.
startTimer:Starts a timer that times out every 5ms.
getLine:Get the oldest line out of the buffer. Called every 5ms.
line: Line that gets sent to the console where it is displayed.
What I Need
While this strategy of delaying the output works for now, it is not very practical when real-time solutions are needed. I know one other strategy which is to set a buffer size. Then when the buffer size is reached, flush the output. This is a much better strategy since the console will not be choking considering lines are being sent in blocks.
But the problem is that if I set a buffer size of say 50 lines, the user will not see any output until 50 lines have been printed. Reducing the buffer size does not really help either, because then it's meant to reduce stress on the console.
How can I make a buffer system so the output is printed in real-time while not having the console dying on me.
