super(arg0, arg1, arg2);
this.arg1 = arg1;
this.style = style;
this.setViewSize(5);
}
@Override
protected void onModelChanged() {
super.onModelChanged();
style.get("first").setVisible(true);
style.get("prev").setVisible(true);
style.get("next").setVisible(true);
style.get("last").setVisible(true);
if (arg1.getCurrentPage() < 2) {
style.get("first").setVisible(false);
}
if (arg1.getCurrentPage() < 1) {
style.get("prev").setVisible(false);
}
if (arg1.getCurrentPage() > arg1.getPageCount() - 2) {
style.get("next").setVisible(false);
}

style.get("last").setVisible(false);
}
}
}
