You'll have to override the scrollable increment methods in your
scrollable component (the thing you add to the scrollpane). Following
code makes scrolling in a JEditorPane really slow. The numeric values
are the number of pixels the view should be moved for a click on the
arrow or in the gray area of the scrollbar.
JEditorPane ePane = new JEditorPane(url) {
public int getScrollableUnitIncrement(Rectangle visibleRect, int
orientation, int direction) {
return 1;
}
public int getScrollableBlockIncrement(Rectangle visibleRect, int
orientation, int direction) {
return 2;
}
};

Why override when he can simply do the following to the scrollpane itself?
myScrollPane.getHorizontalScrollBar().setUnitIncrement(10);
myScrollPane.getVerticalScrollBar().setUnitIncrement(10);
Those work fine for me when having a jlist in a scrollpane.
Damn, I was looking for such method in JScrollPane and in JViewport,
never occured to me to look on the scrollbars to set them.
Thanks,
Bart
