QtGui.QSplitter

QtGui.QSplitter lets the user control the size of child widgets by dragging the boundary between the children. In our example, we show three QtGui.QFrame widgets organized with two splitters.

import sys
from PyQt4 import QtGui, QtCore

class Example(QtGui.QWidget):
    
    def __init__(self):
        super(Example, self).__init__()
        
        self.initUI()
        
    def initUI(self):      

        hbox = QtGui.QHBoxLayout(self)

        topleft = QtGui.QFrame(self)
        topleft.setFrameShape(QtGui.QFrame.StyledPanel)
 
        topright = QtGui.QFrame(self)
        topright.setFrameShape(QtGui.QFrame.StyledPanel)

        bottom = QtGui.QFrame(self)
        bottom.setFrameShape(QtGui.QFrame.StyledPanel)

        splitter1 = QtGui.QSplitter(QtCore.Qt.Horizontal)
        splitter1.addWidget(topleft)
        splitter1.addWidget(topright)

        splitter2 = QtGui.QSplitter(QtCore.Qt.Vertical)
        splitter2.addWidget(splitter1)
        splitter2.addWidget(bottom)

        hbox.addWidget(splitter2)
        self.setLayout(hbox)
        QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Cleanlooks'))
        
        self.setGeometry(300, 300, 300, 200)
        self.setWindowTitle('QtGui.QSplitter')
        self.show()
        
def main():
    
    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()    

In our example, we have three frame widgets and two splitters.

topleft = QtGui.QFrame(self)
topleft.setFrameShape(QtGui.QFrame.StyledPanel)

We use a styled frame in order to see the boundaries between the QtGui.QFrame widgets.

splitter1 = QtGui.QSplitter(QtCore.Qt.Horizontal)
splitter1.addWidget(topleft)
splitter1.addWidget(topright)

We create a QtGui.QSplitter widget and add two frames into it.

splitter2 = QtGui.QSplitter(QtCore.Qt.Vertical)
splitter2.addWidget(splitter1)

We can also add a splitter to another splitter widget.

QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Cleanlooks'))

We use a Cleanlooks style. In some styles the frames are not visible.
