Method Detail

getBounds

public GRectangle getBounds()

Description copied from class: GObject

Returns the bounding box of this object, which is defined to be the smallest rectangle that covers everything drawn by the figure. The coordinates of this rectangle do not necessarily match the location returned by getLocation. Given a GLabel object, for example, getLocation returns the coordinates of the point on the baseline at which the string begins; getBounds, by contrast, returns a rectangle that covers the entire window area occupied by the string.

Specified by:

getBounds in class GObject

Returns:

The bounding box for this object

contains

public boolean contains(double d,
                        double d1)

Description copied from class: GObject

Checks to see whether a point is inside the object. By default, this method simply checks to see if the point is inside the bounding box. Many subclasses will need to override this to check whether the point is contained in the shape.

Overrides:

contains in class GObject

Parameters:

d - The x-coordinate of the point being tested

d1 - The y-coordinate of the point being tested

Returns:

true if the point (x, y) is inside the object, and false otherwise

paint2d

protected void paint2d(Graphics2D graphics2d)

Description copied from class: GObject

All subclasses of GObject must define a paint2d method which allows the object to draw itself on the Graphics context passed in as the parameter g.

Specified by:

paint2d in class GObject

Parameters:

graphics2d - The graphics context into which the painting is done

setFilled

public void setFilled(boolean flag)

Specified by:

setFilled in interface acm.graphics.GFillable

isFilled

public boolean isFilled()

Specified by:

isFilled in interface acm.graphics.GFillable

setFillColor

public void setFillColor(Color color)

Specified by:

setFillColor in interface acm.graphics.GFillable

getFillColor

public Color getFillColor()

Specified by:

getFillColor in interface acm.graphics.GFillable

setSize

public void setSize(double d,
                    double d1)

Description copied from interface: GResizable

Changes the size of this object to the specified width and height.

Specified by:

setSize in interface GResizable

Parameters:

d - The new width of the object

d1 - The new height of the object

setSize

public final void setSize(acm.graphics.GDimension gdimension)

Description copied from interface: GResizable

Changes the size of this object as specified by the GDimension object.

Specified by:

setSize in interface GResizable

Parameters:

gdimension - A GDimension object specifying the new size

getSize

public acm.graphics.GDimension getSize()

Description copied from class: GObject

Returns the size of the bounding box for this object.

Overrides:

getSize in class GObject

Returns:

The size of this object

setBounds

public void setBounds(double d,
                      double d1,
                      double d2,
                      double d3)

Description copied from interface: GResizable

Changes the bounds of this object to the specified values.

Specified by:

setBounds in interface GResizable

Parameters:

d - The new x-coordinate for the object

d1 - The new y-coordinate for the object

d2 - The new width of the object

d3 - The new height of the object

setBounds

public final void setBounds(GRectangle grectangle)

Description copied from interface: GResizable

Changes the bounds of this object to the values from the specified GRectangle.

Specified by:

setBounds in interface GResizable

Parameters:

grectangle - A GRectangle specifying the new bounds
