在UI类中,触发按钮事件

public void afterEdit(BillEditEvent event) {
		if(event.getKey().equals("pitchname")){
			String pitchname = this.getBillCardPanel().getHeadItem("pitchname").toString();
			if(pitchname != null && pitchname.length() > 0){
				//关键点
				super.onButtonClicked(this.getButtonManager().getButton(IBillButton.Save));
			}
		}
	}
