PyQt QGridLayout（）行为异常

Question

我试图使GUI应用程序正常工作，但是不幸的是，单个画布对象的间距不符合预期。我想具有以下布局：

对于网格布局，我使用以下代码：

# Adapt Widget StyleSheet
self.button_classification.setStyleSheet("font: bold 10pt Consolas; color: #009682")  # #009682 is the KIT-Green
self.button_start.setStyleSheet('font: bold 10pt Consolas; color: #009682; border-style: outset; border-width: 2px; border-radius: 10px; border-color: #646873; padding: 6px')
self.layout4_image_widget.setStyleSheet('background-image: url(Python_logo.png);')

# Define Layouts
self.window = QWidget()
self.layout = QGridLayout()

# Add Widgets to layouts
self.layout.addWidget(self.canvas_left, 0, 0, 5, 5)
self.layout.addWidget(self.canvas_right, 0, 5, 5, 5)
self.layout.addWidget(self.canvas_right_buttom, 8, 7, 3, 3)
self.layout.addWidget(self.canvas_right_top, 5, 7, 3, 3)
self.layout.addWidget(self.canvas_middle_buttom, 8, 3, 3, 4)
self.layout.addWidget(self.canvas_middle_top, 5, 3, 3, 4)
self.layout.addWidget(self.layout4_image_widget, 5, 0, 3, 3)
self.layout.addWidget(self.button_start, 8, 0, 1, 3)
self.layout.addWidget(self.button_classification, 9, 0, 1, 3)
self.layout.addWidget(self.LCD_Number, 10, 0, 1, 3)
self.window.setLayout(self.layout)

但是很遗憾，我收到的结果是：

所以中间5-7的行要宽。

也许与此功能有关……他们说拉伸因子与该行的相对空间占用有关，并且其默认值为0。您可以尝试将每行设置为1。] >
