关于QTableWidget中setRangeSelected的问题

[weixin_38066328]

我想用QTableWidget显示一些条目，鼠标点选一个格子则自动选一行connect(imagefilesTable, SIGNAL(currentItemChanged(QTableWidgetItem*, QTableWidgetItem*)),            this, SLOT(showImage(QTableWidgetItem*)));void MainWindow::showImage(QTableWidgetItem* item){    if (item && item == imagefilesTable->currentItem()) {    imagefilesTable->setRangeSelected(QTableWidgetSelectionRange(item->row(),0,item->row(),7), true);  //0和7栏在表格范围内    }}为啥执行了setRangeSelected之后没效果？选择的还是单元格。。。哪位大虾能帮帮小弟？谢谢！
