      Returns:
      DrawOval instance, for chaining setter calls

      Parameters:
      left - new left coordinate. Default value is 0
      Returns:
      DrawOval instance, for chaining setter calls

    • setRadius

      public DrawOval setRadius(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
      Returns:
      DrawOval instance, for chaining setter calls

    • 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
