Class DateTimeFactory

java.lang.Object

org.eclipse.jface.widgets.AbstractWidgetFactory<DateTimeFactory, DateTime, Composite>

org.eclipse.jface.widgets.AbstractControlFactory<DateTimeFactory, DateTime>

org.eclipse.jface.widgets.DateTimeFactory

public final class DateTimeFactory
extends AbstractControlFactory<DateTimeFactory, DateTime>

This class provides a convenient shorthand for creating and initializing DateTime. This offers several benefits over creating with widget the normal way:

• The same factory can be used many times to create several instances
• The setters all return "this", allowing them to be chained
• The onSelect(Consumer)) accepts a Lambda for SelectionEvent

Example usage:

DateTime DateTime = DateTimeFactory.newDateTime(SWT.BORDER) //
                .onSelect(event -> DateTimeClicked(event)) //
                .layoutData(gridData) //
                .create(parent);

The above example creates a new DateTime, registers a SelectionListener and finally creates the DateTime in "parent".

GridDataFactory gridDataFactory = GridDataFactory.swtDefaults();
DateTimeFactory DateTimeFactory = DateTimeFactory.newDateTime(SWT.BORDER).onSelect(event -> DateTimeClicked(event))
                .layout(gridDataFactory::create);
DateTimeFactory.create(parent);
DateTimeFactory.create(parent);
DateTimeFactory.create(parent);

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

Method Details

newDateTime

public static DateTimeFactory newDateTime(int style)

Creates a new DateTimeFactory with the given style. Refer to DateTime(Composite, int) for possible styles.

Returns:

a new DateTimeFactory instance

onSelect

public DateTimeFactory onSelect(Consumer<SelectionEvent> consumer)

Creates a SelectionListener and registers it for the widgetSelected event. If the receiver is selected by the user the given consumer is invoked. The SelectionEvent is passed to the consumer.

Parameters:

consumer - the consumer whose accept method is called

Returns:

this

onDefaultSelect

public DateTimeFactory onDefaultSelect(Consumer<SelectionEvent> consumer)

Creates a SelectionListener and registers it for the widgetDefaultSelected event. If the receiver is selected by the user the given consumer is invoked. The SelectionEvent is passed to the consumer.

Parameters:

consumer - the consumer whose accept method is called

Returns:

this
