pyqt5 列表内添加按钮

Posted 2020-10-06 yuanlp

我们想在操作列表内添加按钮，例如查看、修改、删除

1、定义添加按钮的方法

 1 # 列表内添加按钮
 2     def buttonForRow(self,id):
 3         widget=QWidget()
 4         # 修改
 5         updateBtn = QPushButton(\'修改\')
 6         updateBtn.setStyleSheet(\'\'\' text-align : center;
 7                                           background-color : NavajoWhite;
 8                                           height : 30px;
 9                                           border-style: outset;
10                                           font : 13px  \'\'\')
11 
12         updateBtn.clicked.connect(lambda:self.updateTable(id))
13 
14         # 查看
15         viewBtn = QPushButton(\'查看\')
16         viewBtn.setStyleSheet(\'\'\' text-align : center;
17                                   background-color : DarkSeaGreen;
18                                   height : 30px;
19                                   border-style: outset;
20                                   font : 13px; \'\'\')
21 
22         viewBtn.clicked.connect(lambda: self.viewTable(id))
23 
24         # 删除
25         deleteBtn = QPushButton(\'删除\')
26         deleteBtn.setStyleSheet(\'\'\' text-align : center;
27                                     background-color : LightCoral;
28                                     height : 30px;
29                                     border-style: outset;
30                                     font : 13px; \'\'\')
31 
32 
33         hLayout = QHBoxLayout()
34         hLayout.addWidget(updateBtn)
35         hLayout.addWidget(viewBtn)
36         hLayout.addWidget(deleteBtn)
37         hLayout.setContentsMargins(5,2,5,2)
38         widget.setLayout(hLayout)
39         return widget

2、在向tableWidget里添加数据时插入即可

1 for row_number, row_data in enumerate(rsdata):
2     self.ui.tableWidget.insertRow(row_number)
3     for i in range(len(row_data)+1):
4         if i<len(row_data):
5             self.ui.tableWidget.setItem(row_number, i, QtWidgets.QTableWidgetItem(str(row_data[i])))
6         # 添加按钮
7         if i==len(row_data):
8             # 传入当前id
9             self.ui.tableWidget.setCellWidget(row_number, i,self.buttonForRow(str(row_data[0])))
