Class SectionFactory

java.lang.Object

org.eclipse.jface.widgets.AbstractWidgetFactory<SectionFactory, Section, Composite>

public final class SectionFactory
extends AbstractCompositeFactory<SectionFactory, Section>

This class provides a convenient shorthand for creating and initializing Section. This offers several benefits over creating Section normal way:

• The same factory can be used many times to create several Section instances
• The setters on SectionFactory all return "this", allowing them to be chained
• SectionFactory accepts a Lambda for ExpansionEvent (see onExpanded(Consumer)) and onExpanding(Consumer)

Example usage:

Section section = SectionFactory.newSection(Section.TWISTIE | Section.DESCRIPTION) //
                .title("My Section") //
                .description("My section created with a factory") //
                .onExpand(event -> sectionExpanded(event)) //
                .create(parent);

The above example creates a section with a title, a description, registers an IExpansionListener and finally creates the section in "parent".

SectionFactory sectionFactory = SectionFactory.newSection(Section.TWISTIE);
sectionFactory.title("Section 1").create(parent);
sectionFactory.title("Section 2").create(parent);
sectionFactory.title("Section 3").create(parent);

The above example creates three section using the same instance of SectionFactory.

Method Details

newSection

public static SectionFactory newSection(int style)

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

Parameters:

style - the style to use

Returns:

a new SectionFactory instance

title

public SectionFactory title(String title)

Sets the title of the section. The title will act as a hyperlink and activating it will toggle the client between expanded and collapsed state.

Parameters:

title - the new title string

See Also:

• ExpandableComposite.setText(String)

description

public SectionFactory description(String description)

Sets the description text. Has no effect if DESCRIPTION style was not used in AbstractWidgetFactory.create(P)

Parameters:

description - new description text; not null

See Also:

• Section.setDescription(String)

description

public SectionFactory description(Function<Section,Control> controlFunction)

Sets a function which must provide a description control for the given Section. The control must not be null and must be a direct child of the section.

This method and DESCRIPTION style are mutually exclusive. Use the method only if you want to create the description control yourself.

Parameters:

controlFunction - the function to create the description control

See Also:

• Section.setDescriptionControl(Control)

onExpanded

public SectionFactory onExpanded(Consumer<ExpansionEvent> consumer)

Creates an IExpansionListener and registers it for the expansionStateChanged event. If the section was expanded by the user the given consumer is invoked. The ExpansionEvent is passed to the consumer.

Parameters:

consumer - the consumer whose accept method is called

Returns:

this

See Also:

• ExpandableComposite.addExpansionListener(IExpansionListener)
• IExpansionListener.expansionStateChanged(ExpansionEvent)

onExpanding

public SectionFactory onExpanding(Consumer<ExpansionEvent> consumer)

Creates an IExpansionListener and registers it for the expansionStateChanging event. If the section is expanded by the user the given consumer is invoked. The ExpansionEvent is passed to the consumer.

Parameters:

consumer - the consumer whose accept method is called

Returns:

this

• ExpandableComposite.addExpansionListener(IExpansionListener)
• IExpansionListener.expansionStateChanging(ExpansionEvent)
