Java javax.swing.plaf.nimbus Class State<T extends JComponent>（JDK8）

Constructor Detail

• State

  protected State(String name)

  Create a new custom State. Specify the name for the state. The name should be unique within the states set for any one particular component. The name of the state should coincide with the name used in UIDefaults.

  For example, the following would be correct:

  
       defaults.put("Button.States", "Enabled, Foo, Disabled");
       defaults.put("Button.Foo", new FooState("Foo"));
   

  Parameters:

  name - a simple user friendly name for the state, such as "Indeterminate" or "EmbeddedPanel" or "Blurred". It is customary to use camel case, with the first letter capitalized.

Method Detail

• toString

  public String toString()

  Description copied from class: Object
  Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

  The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

   getClass().getName() + '@' + Integer.toHexString(hashCode())
   

  Overrides:

  toString in class Object

  Returns:

  a string representation of the object.

• isInState

  protected abstract boolean isInState(T c)

  Gets whether the specified JComponent is in the custom state represented by this class. This is an extremely performance sensitive loop. Please take proper precautions to ensure that it executes quickly.

  Nimbus uses this method to help determine what state a JComponent is in. For example, a custom State could exist for JProgressBar such that it would return true when the progress bar is indeterminate. Such an implementation of this method would simply be:

   return c.isIndeterminate();

  Parameters:

  c - the JComponent to test. This will never be null.

  Returns:

  true if c is in the custom state represented by this State instance
