QT網格佈局橫跨多個列

Question

我試圖創建此geometery：

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

凡1盒又高又瘦，2盒短而寬。我無法完全正確地確定佈局。當我將rowSpan和columnSpan從1到2從0變爲1時，我看到底部框的正確相對位置，但高度錯誤，框1的寬度錯誤。

這使QQ幫助，但並沒有完全解決我的問題：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

您需要設置一個適當的拉伸係數，改變給每個行/列的空間量：

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) 

結果：
