pyqt创建网格布局并加入两个控件

可以按照以下步骤创建网格布局并加入两个控件：

1. 导入 PyQt 模块

from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QLabel, QLineEdit
import sys

2. 创建应用程序实例和窗口实例

app = QApplication(sys.argv)
window = QWidget()

3. 创建网格布局实例并将其设置为窗口的布局

gridLayout = QGridLayout()
window.setLayout(gridLayout)

4. 创建两个控件实例，例如一个标签和一个文本框

label = QLabel('Label')
lineEdit = QLineEdit()

5. 将控件添加到网格布局中

gridLayout.addWidget(label, 0, 0)
gridLayout.addWidget(lineEdit, 0, 1)

6. 显示窗口

window.show()
sys.exit(app.exec_())

完整代码如下：

from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QLabel, QLineEdit
import sys

app = QApplication(sys.argv)
window = QWidget()

gridLayout = QGridLayout()
window.setLayout(gridLayout)

label = QLabel('Label')
lineEdit = QLineEdit()

gridLayout.addWidget(label, 0, 0)
gridLayout.addWidget(lineEdit, 0, 1)

window.show()
sys.exit(app.exec_())
