Re: why are important methods in HTMLTable protected?

Look at this: I have a parent widget with an inner class like this:

public class ContainerWidget extends Composite {

private FlowPanel panel = new FlowPanel();

public ContainerWigget() {

//But then, IllegalStateException is thrown here. I don't why

panel.add(new FrontContentPanel());

initWidget(panel);

}

class FrontContentPanel extends HTMLTable {

FlowPanel frontcontentpanel = new FlowPanel();

Grid featureGrid = new Grid(2, 2);

public FrontContentPanel() {

frontcontentpanel.setStyleName("gwt-FrontContentArea");

            

          featureGrid.setBorderWidth(1);

          featureGrid.setCellPadding(3);

          featureGrid.setCellSpacing(3);

          featureGrid.addStyleName("gwt-featureGrid");
          frontcontentpanel.add(featureGrid);

// I can use any of HTMLTable method here once overridden

initWidget(frontcontentpanel);

}

        /*@Override

        public void setCellFormatter(HTMLTable.CellFormatter cellFormatter) {

            

        }

        @Override

        public int getCellCount(int i) {

            throw new UnsupportedOperationException("Not supported yet.");

        }

}

}

When I try to add the inner class to its super (as seen above), I get a IllegalStateException and my app is not initialized.

Alternatively,

public class ContainerWidget extends Composite {

private final FlowPanel panel = new FlowPanel();

public ContainerWidget() {

// Works without issues

panel.add(new FrontContentPanel());

initWidget(panel);

}

class FrontContentPanel extends Composite {

FlowPanel frontcontentpanel = new FlowPanel();

Grid featureGrid = new Grid(2, 2);

public FrontContentPanel() {

frontcontentpanel.setStyleName("gwt-FrontContentArea");

            

          featureGrid.setBorderWidth(1);

          featureGrid.setCellPadding(3);

          featureGrid.setCellSpacing(3);

          featureGrid.addStyleName("gwt-featureGrid");

          frontcontentpanel.add(featureGrid);

// Now I need access to insertCells(), setCellFormatter(HTMLTable.CellFormatter cellFormatter) etc

initWidget(frontcontentpanel);

}

}

}

Then I can't use most of HTMLTable fine methods. If I use a getCellFormatter, where will the values be coming from? It hasn't been set anywhere in my app. Also, do you know if it is possible to have more than one row in a cell; just like the normal HTML table multiple <td> in a <tr>? I can't seem to find any method in HTMLTable or it's subclasses doing this.

Sub classes of HTMLTable provide their own Cell/Column/RowFormatters (either the default one or a sub class of the default one). So if you use Grid or FlexTable you only have to call getCell/Column/RowFormatter to style your columns/rows/cells. Why do you want to set a Formatter from outside the Grid/FlexiTable class?
