- public final class LongProgressBar
- extends javax.swing.JProgressBar
A progress bar that doesn't pack a sad when you feed it longs (such as the sizes of files) which get mangled into negative numbers. I know how it feels, as I often have negative progress. Also tries to be efficent when updating the JProgressBar, so only updates when the value actually changes, which become necessary when you move a large number of files with millions of bytes (where upon shifting a file of a thousand bytes would be pretty insignificant, maybe not even a percent, but would fire several progress updates).

setIndeterminate
public void setIndeterminate(boolean state)
- Description copied from class:
javax.swing.JProgressBar
- This method changes the indeterminate property. If the
JProgressBar is determinate, it paints a percentage
of the bar described by its value. If it is indeterminate,
it simply bounces a box between the ends of the bar; the
value of the JProgressBar is ignored.
setMaximum
public void setMaximum(int size)
- Description copied from class:
javax.swing.JProgressBar
- This method sets the maximum value of this JProgressBar.
setMaximum
public void setMaximum(long size)
setString
public void setString(java.lang.String label)
- Description copied from class:
javax.swing.JProgressBar
- This method changes the string property. The string
given will be the one painted. If you want to
revert to the default string given, set the
string to null.
setValue
public void setValue(int size)
- Description copied from class:
javax.swing.JProgressBar
- This method sets the value of the JProgressBar.
setValue
public void setValue(long size)
unsafeSetIndeterminate
public void unsafeSetIndeterminate(boolean state)
- This method is an unsafe way to set the progress bar to be indeterminate, -unless- it is called from the Event Queue.
unsafeSetString
public void unsafeSetString(java.lang.String label)
unsafeSetValue
public void unsafeSetValue(int value)
update
private void update()
safeSetString
private void safeSetString(java.lang.String label)
- Change the string displayed on the progress bar.
safeSetValue
private void safeSetValue(int ammount)
- Increase the value of the progress bar.
