2. 상세 내용

• QHBoxLayout : 수평(Horizontal)으로 쌓는 레이아웃

QHBoxLayout - Qt for Python

This class is used to construct horizontal box layout objects. See for details. The simplest use of the class is like this: First, we create the widgets we want in the layout. Then, we create the object and add the widgets into the layout. Finally, we call to install the object onto the widget.

• QVBoxLayout : 수직(Vertical)으로 쌓는 레이아웃

QVBoxLayout - Qt for Python

This class is used to construct vertical box layout objects. See for details. The simplest use of the class is like this: First, we create the widgets we want in the layout. Then, we create the object and add the widgets into the layout. Finally, we call to install the object onto the widget.

https://doc.qt.io/qtforpython/PySide2/QtWidgets/QVBoxLayout.html

vbox1 = QVBoxLayout() 
vbox2 = QVBoxLayout()
        
vbox1.addWidget(label1_img) 
vbox1.addWidget(label1) 

vbox2.addWidget(label2_img) 
vbox2.addWidget(label2) 

hbox = QHBoxLayout()
hbox.addLayout(vbox1)  
hbox.addLayout(vbox2) 
       
self.setLayout(hbox)

• addWidget(추가할 위젯)

• 여기서는 hbox(수평 레이아웃에) 1개의 vbox(수직 레이아웃)이 담겨진 상태

• setLayout(연결시킬 레이아웃)
