qt gridlayout跨越多列

Question

我正在尝试创建这种几何图形：

 _ ___
| |   |
|1| 3 |
|_|___|
  |_2_|

如果1盒高而瘦，则2盒子短而宽。我无法完全理解布局。当我将rowSpan和columnSpan从1和2装入0到1时，我看到底部框位于正确的相对位置，但高度错误，框1的宽度错误。

这样qq有帮助，但没有完全解决我的问题：How to arrange the items in QGridLayout as shown?

import sys
from PyQt4 import QtGui
class Example(QtGui.QWidget):
    def __init__(self):
        super(Example, self).__init__()
        self.initUI()

    def initUI(self):
        textEdit1 = QtGui.QTextEdit("LHS rectangle")      
        textEdit2 = QtGui.QTextEdit("Bottom rectangle")      
        textEdit3 = QtGui.QTextEdit("Central square")      
        self.gridLayout = QtGui.QGridLayout()
        self.gridLayout.addWidget(textEdit1, 0, 0, 2, 0) 
        self.gridLayout.addWidget(textEdit2, 2, 1, 0, 2)
        self.gridLayout.addWidget(textEdit3, 0, 1, 2, 2) 
        self.setLayout(self.gridLayout)
        self.show()

def main():
    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

Answer 1

您需要设置适当的拉伸系数以更改给予每行/列的空间量：

    self.gridLayout.addWidget(textEdit1, 0, 0)
    self.gridLayout.addWidget(textEdit2, 1, 1)
    self.gridLayout.addWidget(textEdit3, 0, 1)
    self.gridLayout.setColumnStretch(0, 1)
    self.gridLayout.setColumnStretch(1, 3)
    self.gridLayout.setRowStretch(0, 3)
    self.gridLayout.setRowStretch(1, 1)

结果：
