Im not sure if anyone can help out here but its worth a shot. In the program im writing we are using jogl for animation and as the anmiation is running we would like to have in our main GUI window the ability to use a JLabel as an animation clock to display the correct times of the animation as well as have a JSlider as a progress bar, with the intention of the user being able to move the JSlider to a position and have the animation go forward and back in time. I wrote a small little app to test how I could do this but it doesnt work. I was basically having a for loop to run through the min and max time and every time the for loop would increment i would call the setText() function of the JLabel and the setValue() function of the JSlider to have the values incremented but when i click the button to accomplish it it never updates the labels or the slider until the program is done running through the for loop. Can anyone help me?
