Constructor Detail

DrawOval

public DrawOval()

DrawOval

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

Method Detail

getOrCreateRef

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

create

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

Overrides:

create in class DrawItem

setCenterPoint

public void setCenterPoint(Point centerPoint)

Center point of the oval. If unset, derived from left/top/width/height.

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

Parameters:

centerPoint - left coordinate. Default value is null

getCenterPoint

public Point getCenterPoint()

Center point of the oval. If unset, derived from left/top/width/height.

Returns:

Point

setHeight

public void setHeight(int height)

Height in pixels.

If this method is called after the component has been drawn/initialized: Set the height of the drawOval

Parameters:

height - new height. Default value is 100

getHeight

public int getHeight()

Height in pixels.

Returns:

int

setLeft

public void setLeft(int left)

Left coordinate in pixels relative to the DrawPane.

If this method is called after the component has been drawn/initialized: Set the left coordinate of the drawOval

Parameters:

left - new left coordinate. Default value is 0

getLeft

public int getLeft()

Left coordinate in pixels relative to the DrawPane.

Returns:

int

setRadius

public void setRadius(java.lang.Integer radius)

Radius of the oval. Since this is used to initialize the horizontal and vertical radii, then the oval is a circle.

If unset, the horizontal and vertical radii are set to half the width and height.

If this method is called after the component has been drawn/initialized: Resize the drawOval by setting its radius, and retaining its current center point. Equivalent to setRadii(radius, radius).

Parameters:

radius - new radius. This will be applied on both axes, meaning calling this method will always result in the DrawOval being a circle.. Default value is null

See Also:

getRadiusX(), getRadiusY()

setTop

public void setTop(int top)

Top coordinate in pixels relative to the DrawPane.

If this method is called after the component has been drawn/initialized: Set the top coordinate of the drawOval

Parameters:

top - new top coordinate. Default value is 0

getTop

public int getTop()

Top coordinate in pixels relative to the DrawPane.

Returns:

int

setWidth

public void setWidth(int width)

Width in pixels.

If this method is called after the component has been drawn/initialized: Set the width of the drawOval

Parameters:

width - new width. Default value is 100

getWidth

public int getWidth()

Width in pixels.

Returns:

int

getCenter

public Point getCenter()

Get the center of the oval.

Returns:

the center point

getRadiusX

public int getRadiusX()

Returns the horizontal radius of the DrawOval.

Returns:

the horizontal radius.

See Also:

setRadii(int, int)

getRadiusY

public int getRadiusY()

Returns the vertical radius of the DrawOval.

Returns:

the vertical radius.

See Also:

setRadii(int, int)

moveBy

public void moveBy(int dX,
          int dY)

Move the drawOval by the specified delta

Overrides:

moveBy in class DrawItem

Parameters:

dX - number of pixels to move horizontally

dY - number of pixels to move vertically

moveTo

public void moveTo(int left,
          int top)

Move the drawOval to the specified left/top position. You may also call DrawOval.setCenterPoint() to reposition the oval around a new center position.

Parameters:

left - new left coordinate

top - new top coordinate

resizeBy

public void resizeBy(int dX,
            int dY)

Resize by the specified delta. Note that the resize will occur from the current top/left coordinates, meaning the center positon of the oval may change. You may also use DrawOval.setRadii() to change the radius in either direction without modifying the centerpoint.

Overrides:

resizeBy in class DrawItem

Parameters:

dX - number of pixels to resize by horizontally

dY - number of pixels to resize by vertically

resizeTo

public void resizeTo(int width,
            int height)

Resize to the specified size. Note that the resize will occur from the current top/left coordinates, meaning the center positon of the oval may change. You may also use DrawOval.setRadii() to change the radius in either direction without modifying the centerpoint.

Overrides:

resizeTo in class DrawItem

Parameters:

width - new width

height - new height

setOval

public void setOval(int cx,
           int cy,
           int rx,
           int ry)

Resize and reposition the drawOval by setting its radius, and centerPoint.

Parameters:

cx - new horizontal center point coordinate

cy - new vertical center point coordinate

rx - new horizontal radius

ry - new vertical radius

setRadii

public void setRadii(int rx,
            int ry)

Resize the drawOval by setting its horizontal and vertical radius, and retaining its current center point.

Parameters:

rx - new horizontal radius

ry - new vertical radius

See Also:

getRadiusX(), getRadiusY()

setRect

public void setRect(int left,
           int top,
           int width,
           int height)

Move and resize the drawOval to match the specified coordinates and size.

Parameters:

left - new left coordinate

top - new top coordinate

width - new width

height - new height

setDefaultProperties

public static void setDefaultProperties(DrawOval drawOvalProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. 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 affect 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. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

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