Method Detail

setDraggableElements

public void setDraggableElements(int mask)

Sets the Draggable elements - the Horizontal or Vertical Direction. One

can use a bitmasked 'or' (HORIZONTAL_SCROLL_BAR | VERTICAL_SCROLL_BAR ).

Parameters:

mask - One of HORIZONTAL_SCROLL_BAR, VERTICAL_SCROLL_BAR, or HORIZONTAL_SCROLL_BAR | VERTICAL_SCROLL_BAR

setScrollingIntensity

public void setScrollingIntensity(int intensity)

Sets the scrolling intensity - the default value being 5. Note, that this has an

inverse relationship to intensity (1 has the biggest difference, higher numbers having

less impact).

Parameters:

intensity - The new intensity value (Note the inverse relationship).

setAnimationTiming

public void setAnimationTiming(int timing)

Sets how frequently the animation will occur in milliseconds. Default

value is 30 milliseconds. 60+ will get a bit flickery.

Parameters:

timing - The timing, in milliseconds.

setDamping

public void setDamping(double damping)

Sets the animation damping.

Parameters:

damping - The new value

mouseEntered

public void mouseEntered(MouseEvent e)

Empty implementation

Specified by:

mouseEntered in interface MouseListener

mouseExited

public void mouseExited(MouseEvent e)

Empty implementation

Specified by:

mouseExited in interface MouseListener

mousePressed

public void mousePressed(MouseEvent e)

Mouse pressed implementation

Specified by:

mousePressed in interface MouseListener

mouseReleased

public void mouseReleased(MouseEvent e)

Mouse released implementation. This determines if further animation

is necessary and launches the appropriate times.

Specified by:

mouseReleased in interface MouseListener

mouseClicked

public void mouseClicked(MouseEvent e)

Empty implementation

Specified by:

mouseClicked in interface MouseListener

mouseDragged

public void mouseDragged(MouseEvent e)

MouseDragged implementation. Sets up timing and frame animation.

Specified by:

mouseDragged in interface MouseMotionListener

mouseMoved

public void mouseMoved(MouseEvent e)

Empty

Specified by:

mouseMoved in interface MouseMotionListener
