              javax.swing.JLabel
                  ch.epfl.craft.maglib.magnet.DefaultMagnetCellRenderer

All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, MagnetCellRenderer, java.awt.MenuContainer, java.io.Serializable, javax.swing.SwingConstants

Direct Known Subclasses:

MagMapMagnetCellRenderer

public class DefaultMagnetCellRenderer

extends javax.swing.JLabel

implements MagnetCellRenderer

Displays a node in a MagnetView.

To customize the way nodes are painted, subclass DefaultMagnetCellRenderer and override getMagnetCellRendererComponent to return a custom component

Implementation Note: This class overrides validate, revalidate, repaint, and firePropertyChange solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default tree cell renderer. If you write your own renderer, take care to weigh the benefits and drawbacks of overriding these methods.

Method Detail

getMagnetCellRendererComponent

public java.awt.Component getMagnetCellRendererComponent(MagnetView view,
                                                         java.lang.Object value,
                                                         boolean selected,
                                                         boolean magnetic,
                                                         boolean mouseIsOver,
                                                         boolean mouseIsNear)

Sets the value of the current magnet cell to value. If selected is true, the cell will be drawn as if selected. view is the MagnetView the receiver is being configured for. mouseOvered and mouseIsNear allow to make some subtle differences in the way the component is rendered depending on the mouse cursor position in the view. Returns the Component that the renderer uses to draw the value.

Specified by:

getMagnetCellRendererComponent in interface MagnetCellRenderer

Parameters:

view - the MagnetView instance for which the component is configured.

value - the object that we want to draw.

selected - true if value is selected, else false.

magnetic - true if the node attracts other nodes.

mouseIsOver - true if the mouse cursor is over the node

mouseIsNear - true if the mouse is near the component.

Returns:

the Component that the renderer uses to draw the value.

paint

public void paint(java.awt.Graphics g)

Paint the component in g.

Parameters:

g - the graphic context in which to draw

repaint

public void repaint(long tm,
                    int x,
                    int y,
                    int width,
                    int height)

Overridden for performance reasons.

Parameters:

tm - this parameter is not used

x - the x value of the dirty region

y - the y value of the dirty region

width - the width of the dirty region

height - the height of the dirty region

repaint

public void repaint(java.awt.Rectangle r)

Overridden for performance reasons.

Parameters:

r - a Rectangle containing the dirty region

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  java.lang.Object oldValue,
                                  java.lang.Object newValue)

Overridden for performance reasons.

Parameters:

propertyName - the programmatic name of the property that was changed

oldValue - the old value of the property (as an Object)

newValue - the new value of the property (as an Object)
