Create a class that renders anchor like below:
public class CustomAnchorCell
extends ClickableTextCell {
private String itsHref = "";
private boolean isEnabled = true;
public CustomAnchorCell(String inHref) {
super();
itsHref = inHref;
}
public CustomAnchorCell() {
super();
itsHref = "";
}
public CustomAnchorCell(String inHref, boolean inEnabled) {
this(inHref);
isEnabled = inEnabled;
}
@Override
protected void render(Context context, SafeHtml value, SafeHtmlBuilder sb) {
if (value != null) {
String theElementStart = "";
String theElementEnd = "";
if (isEnabled) {
theElementStart = "<a href='" + itsHref + "'";
theElementEnd = "</a>";
} else {
theElementStart = "<span";
theElementEnd = "</span>";
}
sb.appendHtmlConstant(theElementStart + " class='" + itsClassName +
"'>")
.append(value)
.appendHtmlConstant(theElementEnd);
}
}
public void setHref(String inHref) {
itsHref = inHref;
}
public void setEnabled(boolean inEnabled) {
isEnabled = inEnabled;
}
public void setClassName(String inClassName) {
itsClassName = inClassName;
}
}
Use it like this:
Column<Report, String> theReport = new Column< Report, String>(new
CustomAnchorCell()) {
@Override
public String getValue(Report object) {
return "Hello New Tab";
}
@Override
public void render(Cell.Context context, Report object, SafeHtmlBuilder sb)
{
CustomAnchorCell theCustomAnchorCell = (CustomAnchorCell) getCell();
theCustomAnchorCell.setHref("_your new tab url_");
theCustomAnchorCell.setClassName(*"_your custom css class name_"*);
super.render(context, object, sb);
}
};
