The list of methods to do Swing Mouse are organized into topic(s).

Method

booleanisLeftMouseButton(MouseEvent anEvent)
Replaces SwingUtilities#isLeftMouseButton() for consistency with other button-related methods 
return (anEvent.getModifiersEx() & InputEvent.BUTTON1_DOWN_MASK) > 0;
booleanisLeftMouseButton(MouseEvent e)
Determines if the event is originated from a left mouse button 
return javax.swing.SwingUtilities.isLeftMouseButton(e);
booleanisPopupTrigger(final MouseEvent e)
Returns whether the specifid mouse events triggers popup menu or not. 
return e.isPopupTrigger() || SwingUtilities.isRightMouseButton(e);
booleanisPrimaryMouseButton(MouseEvent e)
Tests if a MouseEvent was triggered by primary mouse button 
return SwingUtilities.isLeftMouseButton(e) && !e.isControlDown();
voidmakeMouseOverBorder(final JComponent b)
Make a mouse over border 
b.setBorder(BorderFactory.createEmptyBorder(1, 1, 1, 1));
b.addMouseListener(new MouseAdapter() {
    public void mouseEntered(MouseEvent e) {
        if (b.isEnabled()) {
            b.setBorder(BorderFactory.createLineBorder(Color.gray));
    public void mouseExited(MouseEvent e) {
...
intmapDragOperationFromModifiers(MouseEvent me, TransferHandler th)
map Drag Operation From Modifiers 
return convertModifiersToDropAction(me.getModifiersEx(), th.getSourceActions((JComponent) me.getSource()));
voidpaintBandTitle(Graphics g, Rectangle titleRectangle, String title, boolean isUnderMouse, boolean hasExpandIcon)
paint Band Title 
Graphics2D g2 = (Graphics2D) g.create();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
Shape s = new RoundRectangle2D.Double(titleRectangle.x, titleRectangle.y, titleRectangle.width,
        titleRectangle.height, 8, 8);
GradientPaint gp1 = new GradientPaint(0, titleRectangle.y + titleRectangle.height / 2,
        new Color(75, 75, 75), 0, titleRectangle.y + titleRectangle.height, new Color(100, 100, 100));
g2.setPaint(gp1);
...
MouseEventparentMouseEvent(JComponent c, MouseEvent m)
build a moue event on the parent coordinates 
Point loc = c.getLocation();
int x = m.getX() + loc.x;
int y = m.getY() + loc.y;
MouseEvent ret = new MouseEvent(c.getParent(), m.getID(), m.getWhen(), m.getModifiers(), x, y,
        m.getClickCount(), m.isPopupTrigger(), m.getButton());
return ret;
voidpassBehind(MouseEvent e)

Pass the event behind. 

JComponent source = (JComponent) e.getSource();
Container parent = source.getParent();
if (parent != null) {
    Point pos = SwingUtilities.convertPoint(source, e.getPoint(), parent);
    MouseEvent event = new MouseEvent(parent, e.getID(), e.getWhen(), e.getModifiers(), pos.x, pos.y,
            e.getClickCount(), e.isPopupTrigger());
    parent.dispatchEvent(event);
voidpropagate(MouseEvent e, Component c)
propagate 
Point p = SwingUtilities.convertPoint(e.getComponent(), e.getX(), e.getY(), c);
MouseEvent e2;
if (e instanceof MouseWheelEvent) {
    e2 = new MouseWheelEvent(c, e.getID(), e.getWhen(), e.getModifiers(), p.x, p.y, e.getClickCount(),
            e.isPopupTrigger(), ((MouseWheelEvent) e).getScrollType(),
            ((MouseWheelEvent) e).getScrollAmount(), ((MouseWheelEvent) e).getWheelRotation());
} else {
    e2 = new MouseEvent(c, e.getID(), e.getWhen(), e.getModifiers(), p.x, p.y, e.getClickCount(),
