+    A progress bar component.
+
+    To use this, just create one and make it visible. It'll run its own timer
+    to keep an eye on a variable that you give it, and will automatically
+    redraw itself when the variable changes.
+
+    If using LookAndFeel_V4 a circular spinning progress bar will be drawn if
+    the width and height of the ProgressBar are equal, otherwise the standard,
+    linear ProgressBar will be drawn.
+
+    For an easy way of running a background task with a dialog box showing its
+    progress, see the ThreadWithProgressWindow class.
