JTrackBar
Initial date: 2007/07/11
Author:xlingFairy
Blog:
Currently, only horizontal and vertical ones have not been written.
Design functions:
When changed, the event onChange is triggered and the current value is passed.
2007/07/12
Added drag function.
2007/07/13
Add skin function
2007/08/06
Add vertical. And fix a bug caused by setRange.
Not made function: specify trackFrequence, you can try to modify it yourself.
Please respect the fruits of labor! The original work information is not allowed! You will bear the consequences at your own risk!
