Progress Bar and Scroller reusable components
The two components I've developed are small in size (light weight), and simple to use. The ProgressBar is written without platform-native code (peerless), while the Scroller combines AWT components by "wrapping" a horizontal and vertical Scrollbar around a Canvas.
Here's a
demo applet using both components.
How to use
the ProgressBar component:
-
Download the ProgressBar
class file and put it in the same directory as the applet class files.
-
Use one of the layout
managers like boarderlayout to position it in the applet.
-
When your applet needs
to update the progress bar, just call the updateBar method.
How
to use the Scroller component:
-
Download the Scroller
and ScrollReadable class files and put them in the same directory as the
applet class files.
-
Subclass a Canvas component
and implement the ScrollReadable interface.
-
Create an array of type
ScrollReadable and insert a reference to the Canvas.
-
Instantiate the Scroller
object passing it a reference to the array of type ScrollReadable, it will
return a Panel.
-
Use one of the layout
managers like boarderlayout to position the Panel in the applet.
-
Whenever a scrollbar
is scrolled, the Scroller object will pass to all objects in the ScrollReadable
array the state of the scroll bars.
