CellPanel

Version 1.0 onwards

An Abstract Panel For Panels With Cells

---

Notes

---

Not something to play with when you are just getting started. It's not one of the basic layout widgets

Useful if you are passing a parameter or creating an abstract class where you don't know if it is going to be a HorizontalPanel, VerticalPanel, or a DockPanel

You can create your own cell panels using this, but it would have to be an exceptional situation.

Code

public void demo()
{
    MyPanel panel = new MyPanel();
    panel.setSize("200px", "130px");
    panel.addStyleName("demo-panel");
    Label label = new Label("Label");
    panel.add(label);
    label.setWidth("100px");
    label.setStyleName("demo-label");
    panel.setCellHeight(label, "100%");
    panel.setCellWidth(label, "100%");
    panel.setCellHorizontalAlignment(label,
        HasAlignment.ALIGN_CENTER);
    RootPanel.get("demo").add(panel);
}
class MyPanel extends CellPanel
{
    public void add(Widget child)
    {
        Element tr = DOM.createTR();
        Element td = DOM.createTD();
        DOM.appendChild(tr, td);
        DOM.appendChild(getBody(), tr);
        super.add(child, td);
    }
}
