Class WPointF

java.lang.Object
eu.webtoolkit.jwt.WJavaScriptExposableObject
eu.webtoolkit.jwt.WPointF
public class WPointF extends WJavaScriptExposableObject
A value class that defines a 2D point.

JavaScript exposability

A WPointF is JavaScript exposable. If a WPointF is JavaScript bound, it can be accessed in your custom JavaScript code through its handle's jsRef(). A point is represented in JavaScript as an array of two elements, e.g. a point WPointF(10,20) will be represented in JavaScript as: 


 [10, 20]

Warning: A WPointF that is JavaScript exposed should be modified only through its handle. Any attempt at modifying it will cause an exception to be thrown.

    • getJsValue

      public String getJsValue()
      Description copied from class: WJavaScriptExposableObject
      Returns a JavaScript representation of the value of this object.

      Note: The value returned will reflect the current server side value of the object. If this object is JavaScript bound, this value may not reflect the actual client side value. If you need access to the client side value, use getJsRef() intead.
