        clone in interface Component
        clone in class LabelImageElement
        the new component. Notice that it doesn't belong to any page, nor desktop. It doesn't have a parent, either.
      • setHflex

        public void setHflex​(java.lang.String flex)
        as of release 6.0.0. To control the hflex of Treecell, please use HtmlBasedComponent.setHflex(String) instead.
        Description copied from class: HtmlBasedComponent
        Sets horizontal flex hint of this component.

        Number flex indicates how this component's container distributes remaining empty space among its children horizontally. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios.

        Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1.

        Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components.

        setHflex in class HtmlBasedComponent
        flex - horizontal flex hint of this component.
