Method Details

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:

• Figure.getClientArea()

getScale

public double getScale()

Returns the current zoom scale level.

Specified by:

getScale in interface ScalableFigure

Returns:

the scale

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)

optimizeClip

public boolean optimizeClip()

Make this method publicly accessible for IScaleablePane.

Specified by:

optimizeClip in interface IScalablePane

Overrides:

optimizeClip in class Figure

Since:

3.13

setScale

public void setScale(double newZoom)

Sets the zoom level

Specified by:

setScale in interface ScalableFigure

Parameters:

newZoom - The new zoom level

useScaledGraphics

public boolean useScaledGraphics()

Specified by:

useScaledGraphics in interface IScalablePane

Since:

3.13

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)

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)

useDoublePrecision

protected boolean useDoublePrecision()

Description copied from class: Figure

Returns true if this Figure should use double-precision arithmetic when translating a Translatable. This method should not be called or overridden by clients. This method is overridden by classes dealing with (fractional) scaling (implementing the ScalableFigure).

Overrides:

useDoublePrecision in class Figure

Returns:

false.

Since:

3.21
