我自定义了ListGrid,可以在其中展开记录并显示展开组件。我知道记录的左上角存在展开/折叠记录的小箭头,但我想知道是否可以手动检查所选记录是否展开或折叠。我希望记录在单击记录时展开/折叠。我的代码示例:
private RecordClickHandler gatherRecordClickHandler() {
return new RecordClickHandler() {
@Override
public void onRecordClick(RecordClickEvent event) {
//Here i want to check if the record is expanded/collapsed
if(/*expanded check method here*/)
collapseRecord(event.getRecord());
else
expandRecord(event.getRecord());
}
};
}
