Enumeration Policy

Example

    // SizePolicy.Policy controls how a widget's size behaves within a layout.
    // Use widget.setSizePolicy(horizontal, vertical) to configure both axes.
    const root = new Widget(parent);
    const layout = new BoxLayout();
    layout.setDirection(Direction.TopToBottom);
    root.layout = layout;

    const fixedLabel = new Label(root);
    fixedLabel.text = 'Fixed height label';
    fixedLabel.setSizePolicy(SizePolicy.Policy.Preferred, SizePolicy.Policy.Fixed);
    layout.addWidget(fixedLabel);

    const expandingLabel = new Label(root);
    expandingLabel.text = 'Expanding label fills remaining space';
    expandingLabel.setSizePolicy(SizePolicy.Policy.Expanding, SizePolicy.Policy.Expanding);
    layout.addWidget(expandingLabel);
