Default constructor for a Builder object.

Method Details

build

public DrawingArea build()

Finish building the DrawingArea object. This will call GObject.withProperties(org.gnome.glib.Type, java.lang.String[], org.gnome.gobject.Value[]) to create a new GObject instance, which is then cast to DrawingArea.

Overrides:

build in class Widget.Builder<B extends DrawingArea.Builder<B>>

Returns:

a new instance of DrawingArea with the properties that were set in the Builder object.

setContentHeight

public B setContentHeight(int contentHeight)

The content height.

Parameters:

contentHeight - the value for the content-height property

Returns:

the Builder instance is returned, to allow method chaining

setContentWidth

public B setContentWidth(int contentWidth)

The content width.

Parameters:

contentWidth - the value for the content-width property

Returns:

the Builder instance is returned, to allow method chaining

onResize

public B onResize(DrawingArea.ResizeCallback handler)

Emitted once when the widget is realized, and then each time the widget is changed while realized.

This is useful in order to keep state up to date with the widget size, like for instance a backing surface.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining
