How to add tooltip to the cells in celltable?

gwt, java

Solution

Here's an abstract tooltip column class that you can extend in place of the normal Column class:

public abstract class MyToolTipColumn<T, C> extends Column<T, C> {

  interface Templates extends SafeHtmlTemplates {

    @Template("<div title=\"{0}\">")
    SafeHtml startToolTip(String toolTipText);

    @Template("</div>")
    SafeHtml endToolTip();

  }

  private static final Templates TEMPLATES = GWT.create(Templates.class);
  private final String toolTipText;

  public MyToolTipColumn(final Cell<C> cell, final String toolTipText) {
    super(cell);
    this.toolTipText = toolTipText;
  }

  @Override
  public void render(final Context context, final T object, final SafeHtmlBuilder sb) {

    sb.append(TEMPLATES.startToolTip(toolTipText));
    super.render(context, object, sb);
    sb.append(TEMPLATES.endToolTip());

  }
}

Problem

I am using gwt cellTable. In this cell table i have one column containing compositeCell. Now i want to add a tooltip for all cells in that composite cell. Any work around for this?
