  • Method Details

    • build

      Finish building the Button object. This will call GObject.withProperties(Type, String[], Value[]) to create a new GObject instance, which is then cast to Button.
      Overrides:
      build in class Widget.Builder<B extends Button.Builder<B>>
      Returns:
      a new instance of Button with the properties that were set in the Builder object.

    • setCanShrink

      public B setCanShrink(boolean canShrink)

      Whether the size of the button can be made smaller than the natural size of its contents.

      For text buttons, setting this property will allow ellipsizing the label.

      If the contents of a button are an icon or a custom widget, setting this property has no effect.

      Parameters:
      canShrink - the value for the can-shrink property
      Returns:
      the Builder instance is returned, to allow method chaining
