Question

有三个框架：顶部，中部和底部。每当我调整底部框架的大小时，顶部框架总是同时调整大小。我希望顶部框架在底部框架调整大小时保持其大小。如何实现？

from PyQt5.QtWidgets import (QWidget, QHBoxLayout, QFrame, 
    QSplitter, QStyleFactory, QApplication)
from PyQt5.QtCore import Qt
import sys

class Example(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()


    def initUI(self):      

        hbox = QHBoxLayout(self)
        top =  QFrame(self)
        top.setFrameShape(QFrame.StyledPanel)

        middle = QFrame(self)
        middle.setFrameShape(QFrame.StyledPanel)

        bottom = QFrame(self)
        bottom.setFrameShape(QFrame.StyledPanel)
        splitter1 = QSplitter(Qt.Vertical)
        splitter1.addWidget(top)
        splitter1.addWidget(middle)
        splitter1.setSizes([300,300])
        splitter2 = QSplitter(Qt.Vertical)
        splitter2.addWidget(splitter1)
        splitter2.addWidget(bottom)
        splitter2.setSizes([600,400])
        hbox.addWidget(splitter2)
        self.setLayout(hbox)

        self.setGeometry(300, 300, 1000, 1000)
        self.setWindowTitle('QSplitter')
        self.show()


if __name__ == '__main__':

    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

如果您希望所有帧彼此独立调整大小，请将它们全部放在同一个分割器中，如下所示：

def initUI(self):
    hbox = QHBoxLayout(self)

    top = QFrame(self)
    top.setFrameShape(QFrame.StyledPanel)
    middle = QFrame(self)
    middle.setFrameShape(QFrame.StyledPanel)
    bottom = QFrame(self)
    bottom.setFrameShape(QFrame.StyledPanel)

    splitter1 = QSplitter(Qt.Vertical)
    splitter1.addWidget(top)
    splitter1.addWidget(middle)
    splitter1.addWidget(bottom)
    splitter1.setSizes([500,300,200])

    hbox.addWidget(splitter1)
    self.setLayout(hbox)

如何在使用QSplitter时修复一个小部件
