尝试在PyQt4图形用户界面中限制每行的QPushbuttons

import sys
from PyQt4.QtGui import QApplication, QWidget, QPushButton, QGridLayout

class MyWidget(QWidget):
    def __init__(self):
        super(MyWidget, self).__init__()

        # 创建QGridLayout布局管理器
        layout = QGridLayout()

        # 创建QPushbuttons并添加到布局中
        for i in range(10):
            button = QPushButton("Button {}".format(i))
            layout.addWidget(button, i // 5, i % 5)  # 每行最多显示5个按钮

        self.setLayout(layout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    widget = MyWidget()
    widget.show()
    sys.exit(app.exec_())
