Returns the minimum value supported by the scrollbar (usually zero).

Usage

From source file:Main.java

/**
 * Scrolls the given component to its top or bottom.
 * Useful for implementing behavior like in Apple's Mail where home/end in the list cause scrolling in the text.
 *///w  ww  .  j  a v a2s. c o m

    JScrollBar scrollBar = ((JScrollPane) SwingUtilities.getAncestorOfClass(JScrollPane.class, c))
            .getVerticalScrollBar();
    scrollBar.setValue(top ? scrollBar.getMinimum() : scrollBar.getMaximum());
}
