Constructor Detail

ScalableLayeredPane

public ScalableLayeredPane()

Method Detail

getClientArea

public Rectangle getClientArea(Rectangle rect)

Description copied from interface: IFigure

Copies the client area into the specificied Recangle, and returns that rectangle for convenience.

Specified by:

getClientArea in interface IFigure

Overrides:

getClientArea in class Figure

Parameters:

rect - The destination rectangle for the client area

Returns:

The same instance that was passed in, modified to contain the client area

See Also:

IFigure.getClientArea(Rectangle)

getMinimumSize

public Dimension getMinimumSize(int wHint,
                                int hHint)

Description copied from interface: IFigure

Returns a hint indicating the smallest desireable size for the IFigure. The returned dimension may be by reference, and it must not be modified by the caller.

Specified by:

getMinimumSize in interface IFigure

Overrides:

getMinimumSize in class Figure

Parameters:

wHint - the width hint

hHint - the height hint

Returns:

The minimum size

See Also:

Figure.getPreferredSize(int, int)

getPreferredSize

public Dimension getPreferredSize(int wHint,
                                  int hHint)

Description copied from interface: IFigure

Returns the preferred size for this IFigure using the provided width and height hints. The returned dimension may be by reference, and it must not be modified by the caller. A value of -1 indicates that there is no constraint in that direction.

Specified by:

getPreferredSize in interface IFigure

Overrides:

getPreferredSize in class Figure

Parameters:

wHint - a width hint

hHint - a height hint

Returns:

The preferred size

See Also:

Figure.getPreferredSize(int, int)

getScale

public double getScale()

Returns the scale level, default is 1.0.

Specified by:

getScale in interface ScalableFigure

Returns:

the scale level

isCoordinateSystem

public boolean isCoordinateSystem()

Description copied from interface: IFigure

Returns true if this figure is capable of applying a local coordinate system which affects its children.

Specified by:

isCoordinateSystem in interface IFigure

Overrides:

isCoordinateSystem in class Figure

Returns:

true if this figure provides local coordinates to children

See Also:

IFigure.isCoordinateSystem()

paintClientArea

protected void paintClientArea(Graphics graphics)

Description copied from class: Figure

Paints this Figure's client area. The client area is typically defined as the anything inside the Figure's Border or Insets, and by default includes the children of this Figure. On return, this method must leave the given Graphics in its initial state.

Overrides:

paintClientArea in class Figure

Parameters:

graphics - The Graphics used to paint

See Also:

Figure.paintClientArea(Graphics)

setScale

public void setScale(double newZoom)

Sets the zoom level

Specified by:

setScale in interface ScalableFigure

Parameters:

newZoom - The new zoom level

translateFromParent

public void translateFromParent(Translatable t)

Description copied from interface: IFigure

Translates a Translatable from this IFigure's parent's coordinates to this IFigure's local coordinates.

Specified by:

translateFromParent in interface IFigure

Overrides:

translateFromParent in class Figure

Parameters:

t - The object to translate

See Also:

Figure.translateFromParent(Translatable)

translateToParent

public void translateToParent(Translatable t)

Description copied from interface: IFigure

Translates a Translatable from this IFigure's coordinates to its parent's coordinates.

Specified by:

translateToParent in interface IFigure

Overrides:

translateToParent in class Figure

Parameters:

t - The object to translate

See Also:

Figure.translateToParent(Translatable)
