Constructor Details

JDEllipse

public JDEllipse(String objectName,
 int x,
 int y,
 int w,
 int h)

Construct a JDEllipse.

Parameters:

objectName - Object name

x - Up left corner x coordinate

y - Up left corner y coordinate

w - Ellipse width

h - Ellipse height

Method Details

copy

public JDObject copy(int x,
 int y)

Description copied from class: JDObject

Returns a copy of this object at the specified location.

Specified by:

copy in class JDObject

Parameters:

x - Horizontal position of the copied object (pixel)

y - Vertical Position of the copied object (pixel)

Returns:

The copy of this object.

isInsideObject

public boolean isInsideObject(int x,
 int y)

Overrides:

isInsideObject in class JDObject

Parameters:

x - X coordinate (pixel)

y - Y coordinate (pixel)

Returns:

whether the specified point is inside this object.

convertToPolyline

public JDPolyline convertToPolyline()

rotate90

public void rotate90(double x,
 double y)

Description copied from class: JDObject

Rotate the object by 90deg. A call to refresh() is needed after transformation.

Overrides:

rotate90 in class JDRectangular

Parameters:

x - Rotation center horizontal pos

y - Rotation center vertical pos

See Also:

• JDObject.refresh()

restoreTransform

public void restoreTransform()

Description copied from class: JDObject

Restore original shape previously backuped by saveTransform

Overrides:

restoreTransform in class JDObject

See Also:

• JDObject.saveTransform()

saveTransform

public void saveTransform()

Description copied from class: JDObject

Backup the shape. This can be usefull when making scaling animation, after multiple scale the rounding may result in deformed shape. To avoid this you can use saveTransform() and restoreTransform(). Note: This is done once when JDrawEditor.loadFile() is called().

Overrides:

saveTransform in class JDObject

See Also:

• JDObject.restoreTransform()

setStep

public void setStep(int s)

Sets the interpolation step of this ellispe.

Parameters:

s - Interpolation step (Default is 10)

getStep

public int getStep()

Returns:

the interpolation step.

See Also:

• setStep(int)

setArcType

public void setArcType(int type)

Sets the arc type for this ellipse.

Parameters:

type - Arc type

See Also:

• ARC_OPEN
• ARC_CLOSED
• ARC_PIE

getArcType

public int getArcType()

Returns:

the current arc type.

See Also:

• setArcType(int)

setAngleStart

public void setAngleStart(int a)

Sets the starting angle of the arc.

Parameters:

a - Angle in degrees.

getAngleStart

public int getAngleStart()

Returns:

the starting angle of the arc.

See Also:

• setAngleStart(int)

setAngleExtent

public void setAngleExtent(int a)

Sets the arc angle extent.

Parameters:

a - Angle extent in degrees.

getAngleExtent

public int getAngleExtent()

Returns:

the arc angle extent.

See Also:

• setAngleExtent(int)

paint

public void paint(JDrawEditor parent,
 Graphics g)

Description copied from class: JDObject

Paints this object.

Overrides:

paint in class JDRectangular

Parameters:

parent - JdrawEditor parent (Can be null except for JDSwingObject)

g - the specified Graphics window
