第一步
//设置treeView可以使用右键菜单
ui->treeView->setContextMenuPolicy(Qt::CustomContextMenu);
第二步,在槽函数添加右键菜单
voidMainWindow::on_treeView_customContextMenuRequested(constQPoint&pos)
{
qDebug()<<"on_treeView_customContextMenuRequested";
QModelIndexindex=ui->treeView->currentIndex();
QStringfileName=ui->treeView->model()->data(index).toString();
QMenu*menu=newQMenu;
menu->addAction(QString(tr("%1-Import").arg(fileName)),this,SLOT(slotTest()));
menu->addAction(QString(tr("%1-Export").arg(fileName)),this,SLOT(slotTest()));
menu->exec(QCursor::pos());
}
