python - 带框架的布局

Question

目前正在研究图形用户界面。我正在尝试使用 3 个 QFrame 进行布局。

如下面的屏幕截图所示，黄色 框位于右侧。我希望该框架位于右框架 之上。 (在小键盘上，占据整个水平空间)

此外，对于右侧框架上的小键盘按钮。我希望它们彼此尽可能靠近，就像键盘上的小键盘一样。我将如何调整网格来做到这一点？

已编辑

这就是我想要的结果。其中红框为rightTopFrame(第一张图中的黄框)。

代码:

def layoutUI(self):
        
        ### Right Top Frame
        self.rightTopFrame = QFrame()
        self.rightTopFrame.resize(1,1)
        self.rightTopFrame.setStyleSheet("background-color: yellow")
        
        
        ### Left Grid
        self.leftGrid = QGridLayout()
        self.leftGrid.setColumnMinimumWidth(10, 10)
        self.leftGrid.setRowMinimumHeight(1, 1) 
        
        # Run, Stop, Speed layout   
        self.leftGrid.addWidget(self.b1, 0, 0)
        self.leftGrid.addWidget(self.b2, 0, 2)
        
        self.leftGrid.addWidget(self.b3, 1, 0)
        self.leftGrid.addWidget(self.l1, 1, 1)
        self.leftGrid.addWidget(self.b4, 1, 2)  
        
        # pl (Pieces and Length) layout     
        self.leftGrid.addWidget(self.b5, 2, 0)
        self.leftGrid.addWidget(self.l2, 2, 1)
        self.leftGrid.addWidget(self.b6, 2, 2)
        
        self.leftGrid.addWidget(self.b7, 3, 0)
        self.leftGrid.addWidget(self.l3, 3, 1)
        self.leftGrid.addWidget(self.b8, 3, 2)
        
        # Manual
        self.leftGrid.addWidget(self.l4, 4, 1)
        
        self.leftGrid.addWidget(self.b9, 5, 0)
        self.leftGrid.addWidget(self.b10, 5, 1)
        self.leftGrid.addWidget(self.b11, 5, 2)



        
        ### Right Grid
        self.rightGrid = QGridLayout()
        self.rightGrid.setColumnMinimumWidth(0, 0)
        self.rightGrid.setRowMinimumHeight(1, 1)    
        
        
        
        self.rightGrid.addWidget(self.np1, 2, 0)
        self.rightGrid.addWidget(self.np2, 2, 1)
        self.rightGrid.addWidget(self.np3, 2, 2)
        self.rightGrid.addWidget(self.np4, 3, 0)
        self.rightGrid.addWidget(self.np5, 3, 1)
        self.rightGrid.addWidget(self.np6, 3, 2)
        self.rightGrid.addWidget(self.np7, 4, 0)
        self.rightGrid.addWidget(self.np8, 4, 1)
        self.rightGrid.addWidget(self.np9, 4, 2)
        self.rightGrid.addWidget(self.np0, 5, 1)
        self.rightGrid.addWidget(self.npCl, 5, 0)
        
        #self.rightGrid.addWidget(self.bExit, 0, 2)
        
        
        
                
        ### Left Frame
        self.leftFrame = QFrame()
        self.leftFrame.resize(150,550)
        #self.leftFrame.setStyleSheet("background-color: red")
        self.leftFrame.setLayout(self.leftGrid)
        
        ### Right Frame
        self.rightFrame = QFrame()
        self.rightFrame.resize(15,50)
        #self.rightFrame.setStyleSheet("background-color: green")
        self.rightFrame.setLayout(self.rightGrid)
        
        
        
        
        
        ### Main Grid
        self.mainGrid = QGridLayout()
        self.mainGrid.setColumnMinimumWidth(10, 0)
        self.mainGrid.addWidget(self.leftFrame)
        self.mainGrid.addWidget(self.rightFrame)
        self.mainGrid.addWidget(self.rightTopFrame)
        
        
        ### Main Interface
        self.setGeometry(300, 200, 850, 450)
        self.setLayout(self.mainGrid)
        self.setStyleSheet("background-color: %s" % backgroundColor)    
        self.setWindowTitle('Signal & slot')
        self.show()

为了使框架位于数字小键盘下方，您必须将它们作为底座放置。为了将按钮放在一起，除了添加 之外，还必须将包含它们的 QGridLayout 中的空间归零({your layout}.setSpacing(0)) QSpacerItem 围绕 QGridLayout。如果您有任何问题，我会将完整的代码留给您。
