Class WidgetFactory

java.lang.Object
org.eclipse.jface.widgets.WidgetFactory
public final class WidgetFactory extends Object
This class provides a convenient shorthand for creating and initializing factories for SWT widgets. This offers several benefits over creating SWT widgets with the low level SWT API
  • The same factory can be used many times to create several widget instances
  • The setters can be chained
  • Factories accept a lambda whenever applicable
Example usage: 
 Button button = WidgetFactory.button(SWT.PUSH) //
                .text("Click me!") //
                .onSelect(event -> buttonClicked(event)) //
                .layoutData(gridData) //
                .create(parent);

The above example creates a push button with a text, registers a SelectionListener and finally creates the button in "parent". 

 GridDataFactory gridDataFactory = GridDataFactory.swtDefaults();
 ButtonFactory buttonFactory = WidgetFactory.button(SWT.PUSH).onSelect(event -> buttonClicked(event))
                .layout(gridDataFactory::create);
 buttonFactory.text("Button 1").create(parent);
 buttonFactory.text("Button 2").create(parent);
 buttonFactory.text("Button 3").create(parent);

The above example creates three buttons using the same instance of ButtonFactory. Note the layout method. A Supplier is used to create unique GridData for every single button.
