 public Point location

 public ListItem()

Constructs a ListItem

 public ListItem(ListContainer container,
                 String title)

Constructs a ListItem with a title

Parameters:

container - the parent ListContainer

title - the title of the ListItem

 public boolean doubleClick(int x,
                            int y)

Method called on a double mouse click

Parameters:

x - the x coordinate of the double click

y - the y coordinate of the double click

 public void move(Point start,
                  int x,
                  int y)

Move this primitive from the current location to a new (x,y)

Parameters:

start - the reference Point at which this move started

x - the x coordinate

y - the y coordinate

 public void drawItem(Graphics g)

Draw the ListItem in the given graphics context

Parameters:

the - graphics context

 public void setBoundingBoxes(Graphics g)

Set the bounding box for this primitive. The Graphics context is required to obtain the FontMetrics for this ListItem.

Parameters:

g - the graphics context

pnts - the vector containing the ListItem location

 public void setParentListContainer(ListContainer container)

set the parent of this ListItem to the given folder

Parameters:

folder - the new parent folder

 public ListContainer getParentListContainer()

get the parent folder of this ListItem

 public void removeMyself()

 public void unselect()

toggle the selected value of this ListItem

 public void select()

 public Object clone()

clone this ListItem

Overrides:

 public void setCanvas(Component canvas)

Sets the component we're drawing into

Parameters:

component - the component

 public Component getCanvas()

 public void setColor(Color color)

Sets the color we're drawing with

Parameters:

the - Color

 public void mouseDown(int x,
                       int y)

Sets up the vector of points we're going to do in this drawing operation, and calls the mouseDownAction with point coordinates.

Parameters:

x - the x coordinate when the mouseDown event occurred.

y - the y coordinate when the mouseDown event occurred.

 public void mouseDrag(int x,
                       int y)

Preforms the mouse dragging operation for this primitive. If the primitive has been selected for a dragging operation, the move method is called. Otherwise, it's a straight drawing operation, so the mouseDragAction method is called.

Parameters:

x - the x coordinate when the mouseDrag event occurred.

y - the y coordinate when the mouseDrag event occurred.

 public void mouseUp(int x,
                     int y)

Preforms the mouse up operation for this primitive. If the primitive has been selected for a dragging operation, nothing is done. Otherwise, it's a straight drawing operation, so the mouseUpAction method is called.

Parameters:

x - the x coordinate when the mouseUp event occurred.

y - the y coordinate when the mouseUp event occurred.

 public final boolean grabbed()

Returns whether or not this primitive has been grabbed

Returns:

a boolean value

 public Point grabbedPoint()

return the point at which the ListItem was grabbed

 public void grab(int x,
                  int y)

Grabs this primitive

Parameters:

x - the x coordinate where the primitive was grabbed

y - the y coordinate where the primitive was grabbed

 public void repaintMe()

 public void release()

Releases the grab on this primitive

 public boolean contains(int x,
                         int y)

Java 1.1 Code

 public boolean intersects(Point point)

 public boolean rightBefore(Point point)

 public boolean rightAfter(Point point)

 public final Rectangle getBoundingBox()

Returns the bounding box for this ListItem

 public String getText()

 public void setArg(Object arg)

 public Object getArg()
