Class GListCellRenderer<E>

  • Type Parameters:
    E - the element-type this list models.
    All Implemented Interfaces:
    GComponent, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, javax.swing.ListCellRenderer<E>, javax.swing.SwingConstants
    public class GListCellRenderer<E>
extends AbstractGCellRenderer
implements javax.swing.ListCellRenderer<E>

      • createDefaultCellTextRenderer

        public static <E> GListCellRenderer<E> createDefaultCellTextRenderer​(java.util.function.Function<E,​java.lang.String> cellToTextMappingFunction)
        Returns a new ListCellRenderer that maps the list's data instance to a string used in the cell.

        Use this if you only need to provide a way to get the string value from the type being shown in the list.

        Parameters:
        cellToTextMappingFunction - a function that maps your custom type to a string value
        Returns:
        new GListCellRenderer instance

      • getItemText

        protected java.lang.String getItemText​(E value)
        Return the cell renderer text
        Parameters:
        value - Cell object value
        Returns:
        A string interpretation of value; generated by calling value.toString()

      • getListCellRendererComponent

        public java.awt.Component getListCellRendererComponent​(javax.swing.JList<? extends E> list,

        Returns the width, height necessary to display the largest element in this list.

        Useful for setting a JList's fixed cell width and height to the actual necessary size.

        NOTE: the items and the renderer must be in plain text mode, not HTML rendering mode.

        Parameters:
        list - the JList that uses this cell renderer
        items - the items to measure
        minWidth - the minimum width that can be returned
        minHeight - the minimum height that can be returned
        Returns:
        a new Dimension containing a width and height value necessary to display the largest element in the list
