Biglistbox Renderer


The implementation of a custom renderer for a Biglistbox (MatrixRenderer) is straightforward[1]:

public class DataRenderer implements org.zkoss.zkmax.zul.MatrixRenderer<List<String>> {
 
    @Override
    public String renderCell(Component owner, List<String> data,
            int rowIndex, int colIndex) throws Exception {
        String d = data.get(colIndex);
        d = d.replace("ZK", "<span class='red' title='ZK'>ZK</span>")
                .replace("Hello", "<span class='blue' title='Hello'>Hello</span>");
        return "<div class='images_" + (colIndex%28) + "' title='x=" +
        colIndex + ",y=" + rowIndex + "'>" + d + "</div>";
    }
 
    @Override
    public String renderHeader(Component owner, List<String> data,
            int rowIndex, int colIndex) throws Exception {
        return "<div class='images_" + (colIndex % 28) + "' title='"
                + images[colIndex % 28] + "'>" + data.get(colIndex)
                + "</div>";
    }
}

Then, if we have a list model (MatrixModel) called data, and an instance of a custom renderer called dataRenderer, then we can put them together in a ZUML document as follows:

<biglistbox model="${data}" matrixRenderer="${dataRenderer}"/>

  1. For the concept about component, model and renderer, please refer to the Model-driven Display section.
