I finally figured out how to add style for button cell. Essentially a
button cell renders an htm button. All you need to do is to extend a
ButtonCell class, then override the render method. In the render
method implementation append the html string on the SafehtmlBuilder.
Like so with style attribute on the html button, basically yes
intercepting the html.
private class MyButtonCell extends ButtonCell
{
/**
* Constructor.
*/
public MyButtonCell()
{
super();
}
/*
* (non-Javadoc)
* @see
com.google.gwt.cell.client.ButtonCell#render(com.google.gwt.cell.client.Cell.Context,
* com.google.gwt.safehtml.shared.SafeHtml,
com.google.gwt.safehtml.shared.SafeHtmlBuilder)
*/
@Override
public void render(final Context context, final SafeHtml data,
final SafeHtmlBuilder sb)
{
sb.appendHtmlConstant("<button type=\"button\" style=
\"width=30px;text-align:center;border-radius:50px;font-family:
Helvetica, Verdana, sans-serif; font-size: 0.9em;font-weight: bold;
font-weight: bold;\""
+ "tabindex=\"-1\">");
if (data != null)
{
sb.append(data);
}
sb.appendHtmlConstant("</button>");
}
}
