?? e802. creating a jprogressbar component with an unknown maximum.txt
字號:
A progress bar with an unknown maximum typically displays an animation until the task is complete.
Note: The percentage display should not be enabled when the maximum is not known (e804 Displaying the Percentage Done on a JProgressBar Component).
// Create a horizontal progress bar
int min = 0;
int max = 100;
JProgressBar progress = new JProgressBar(min, max);
// Play animation
progress.setIndeterminate(true);
When information on the task's progress is available, the progress bar can be made determinate:
int value = 33;
progress.setValue(value);
progress.setIndeterminate(false);
