Extending widget classes

ZIETrans provides a number of widget classes. You can extend any of the widget classes found in the ComponentWidget.xml file by replacing the

public class MyCustomWidget extends Widget implements SwtRenderer

in the created .java file for the new widget with the class name of an existing widget, such as

public class MyCustomWidget extends 
  com.ibm.hats.rcp.transform.widgets.SwtFieldWidget

Note: Bidirectional widgets are stored in the com.ibm.hats.transform.widgets.BIDI package. The names of bidirectional classes for widgets are the same as regular widgets, but they are followed by "BIDI"; for example,

public class newBIDIField extends 
  com.ibm.hats.rcp.transform.widgets.BIDI.SwtFieldWidgetBIDI implements SwtRenderer

If you want to modify an existing widget, you must extend one of the existing widget classes and override its drawSwt method. Refer to the ZIETrans API References (Javadoc) for details about widget interfaces and methods. See Using the API documentation (Javadoc).
