There are several different datatypes, but I won’t go into detail about them here. When working with computer code, we must tell the computer what type of data we want it to work with. This is because we set the script parameter “overlay” to “true”. Alternatively, you can replace the default with a different string by calling setString.Notice that the blue line is no longer drawn in its own indicator box, but is now drawn directly onto the price chart. By default, the progress bar displays the value returned by its getPercentComplete method formatted as a percent, such as 33%. The call to setStringPainted causes the progress bar to display, within its bounds, a textual indication of the percentage of the task that has completed.

The code snippet also sets the progress bar's current value to 0. However, a progress bar's minimum and maximum values can be any value, even negative. The minimum and maximum values used in this program are 0 and the length of the task, which is typical of many programs and tasks. You can also set these values with setMinimum and setMaximum. The constructor that creates the progress bar sets the progress bar's minimum and maximum values. ProgressBar = new JProgressBar(0, task.getLengthOfTask()) Here's a picture of a small demo application that uses a progress bar to measure the progress of a task that runs in its own thread:

You can get the stream's progress monitor with a call to getProgressMonitor and configure it as described in How to Use Progress Monitors.Īfter you see a progress bar and a progress monitor in action, Deciding Whether to Use a Progress Bar or a Progress Monitor can help you figure out which is appropriate for your application. You use an instance of this stream like any of the other input streams described inīasic I/O. ProgressMonitorInputStream An input stream with an attached progress monitor, which monitors reading from the stream. See How to Use Progress Monitors for details and an example of using a progress monitor. Instead, an instance of this class monitors the progress of a task and pops up a dialog if necessary. The section Using Indeterminate Mode tells you how to animate a progress bar to show activity before the task's scope is known. See Using Determinate Progress Bars for information and an example of using a typical progress bar. Swing provides three classes to help you use progress bars: JProgressBar A visible component to graphically display how much of a total task has completed. In the Java look and feel, indeterminate progress bars look like this: As soon as the progress bar can display more meaningful information, you should switch it back into its default, determinate mode. A progress bar in indeterminate mode displays animation to indicate that work is occurring.

You can show work without measurable progress by putting the progress bar in indeterminate mode. Sometimes you can't immediately determine the length of a long-running task, or the task might stay stuck at the same state of completion for a long time. To convey how complete a task is, you can use a progress bar like this one: tCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR))
