Constructor Detail

ProgressMonitor

public ProgressMonitor(Component parentComponent,
                       Object message,
                       String note,
                       int min,
                       int max)

Enabled: Constructs a graphic object that shows progress, typically by filling in a rectangular bar as the process nears completion.

Parameters:

parentComponent - the parent component for the dialog box

message - a descriptive message that will be shown to the user to indicate what operation is being monitored. This does not change as the operation progresses. See the message parameters to methods in JOptionPane.message for the range of values.

note - a short note describing the state of the operation. As the operation progresses, you can call setNote to change the note displayed. This is used, for example, in operations that iterate through a list of files to show the name of the file being processes. If note is initially null, there will be no note line in the dialog box and setNote will be ineffective

min - the lower bound of the range

max - the upper bound of the range
