Constructor Detail

DrawSector

public DrawSector()

DrawSector

public DrawSector(com.google.gwt.core.client.JavaScriptObject jsObj)

Method Detail

getOrCreateRef

public static DrawSector getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

setJavaScriptObject

public void setJavaScriptObject(com.google.gwt.core.client.JavaScriptObject jsObj)

Overrides:

setJavaScriptObject in class DrawItem

create

public com.google.gwt.core.client.JavaScriptObject create()

Overrides:

create in class DrawItem

setCenterPoint

public void setCenterPoint(Point centerPoint)

Center point of the sector

If this method is called after the component has been drawn/initialized: Change the center point for this sector.

Parameters:

centerPoint - left coordinate. Default value is [0,0]

getCenterPoint

public Point getCenterPoint()

Center point of the sector

Returns:

Point

setEndAngle

public void setEndAngle(float endAngle)
                 throws java.lang.IllegalStateException

End angle of the sector in degrees.

Parameters:

endAngle - endAngle Default value is 20.0

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getEndAngle

public float getEndAngle()

End angle of the sector in degrees.

Returns:

float

setKnobs

public void setKnobs(KnobType... knobs)

NOTE: DrawSector items do not support knobs.

Overrides:

setKnobs in class DrawItem

Parameters:

knobs - knobs Default value is null

getKnobs

public KnobType[] getKnobs()

NOTE: DrawSector items do not support knobs.

Overrides:

getKnobs in class DrawItem

Returns:

KnobType

setRadius

public void setRadius(int radius)
               throws java.lang.IllegalStateException

Radius of the sector.

Parameters:

radius - radius Default value is 100

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getRadius

public int getRadius()

Radius of the sector.

Returns:

int

setStartAngle

public void setStartAngle(float startAngle)
                   throws java.lang.IllegalStateException

Start angle of the sector in degrees.

Parameters:

startAngle - startAngle Default value is 0.0

Throws:

java.lang.IllegalStateException - this property cannot be changed after the underlying component has been created

getStartAngle

public float getStartAngle()

Start angle of the sector in degrees.

Returns:

float

moveBy

public void moveBy(int x,
          int y)

Move the drawSector to the specified position.

Overrides:

moveBy in class DrawItem

Parameters:

x - number of pixels to move by horizontally

y - number of pixels to move by vertically

moveTo

public void moveTo(int x,
          int y)

Move the drawSector by the specified delta

Parameters:

x - coordinate to move to horizontally

y - coordinate to move to vertically

resizeBy

public void resizeBy(int dX,
            int dY)

Resize by the specified delta. Note that the resize delta will be applied to each point.

Overrides:

resizeBy in class DrawItem

Parameters:

dX - number of pixels to resize by horizontally

dY - number of pixels to resize by vertically

setDefaultProperties

public static void setDefaultProperties(DrawSector drawSectorProperties)

Class level method to set the default properties of this class. If set, then all subsequent instances of this class will automatically have the default properties that were set when this method was called. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will effect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead.

Parameters:

drawSectorProperties - properties that should be used as new defaults when instances of this class are created
