python pyqt5 QTableWidget 添加右键菜单

'''

【简介】

PyQT5的表格中支持右键菜单例子

'''

import sys

from PyQt5.QtWidgets import (QMenu, QPushButton, QWidget, QTableWidget, QHBoxLayout, QApplication, QTableWidgetItem,

QHeaderView)

from PyQt5.QtCore import QObject, Qt

class Table(QWidget):

if name == ' main ':

app = QApplication(sys.argv)

example = Table()

example.show()

sys.exit(app.exec_())

下面是我给treeWidget加的右键。。。楼主参考下，改下就可以了 复制代码 private slots: on_treeWidget_customContextMenuRequested(QPoint pos) 复制代码 ui->treeWidget->setContextMenuPolicy(Qt::CustomContextMenu)void Composer::on_treeWidget_customContextMenuRequested(QPoint pos) { currentItem = ui->treeWidget->itemAt( pos ) if( currentItem == 0) return QMenu *treeWidgeMenu = new QMenu(ui->treeWidget) treeWidgeMenu->addAction(ui->actionS_rename)treeWidgeMenu->addAction(ui->actionCollpase_Rooms)treeWidgeMenu->addAction(ui->actionUpdate_Driver)treeWidgeMenu->addSeparator()treeWidgeMenu->addAction(ui->actionS_delete)treeWidgeMenu->exec(QCursor::pos())}
