While setting up a dynamic component in my program, I noticed that there was some flickering whenever the component (a JPanel) was relocated. So, I printed the mouse position at each drag event using:
public void mouseDragged(MouseEvent e) {
System.out.println(e.getX());
}
And it came out with some interesting results. With normal-speed drag from left to right, I got the following output in the console:
49
47
...
55
53
58
56
61
59
64
62
67
65
70
65
73
68
76
71
79
74
...
97
92
100
95
103
95
106
You'll notice the numbers fluctuate up then down as the tracking proceeds. I've fixed this before by throwing some math at it, but it now I'm wondering why and how I can make it work normally. Are certain MouseEvents processed before their event predecessors?
