1. Encapsulated main window class
Step 1: Encapsulate the window class
Step 2: Add a drawer interface
Step 3: Add the relevant layout of the drawer interface
Step 4: Click trigger for each drawer interface
Second, the packaged drawer class
0x01 Preface:
Drawer layout (only one interface is displayed at a time)
Requires module: QStackedLayout
The complete code consists of three parts: encapsulated main window class + encapsulated drawer class + program entry program
Ideas:
1. Package window class
2. First, there is a drawer interface
3. Then there are multiple drawers (interface) in the drawer interface
4. Encapsulate multiple separate drawer classes
1. Encapsulated main window class
Step 1: Encapsulate the window class
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.create_stack_layout()
self.init_ui()Step 2: Add a drawer interface
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.create_stack_layout()
self.init_ui()
#————————————————————————————————————————————————————————————————
# 下面为新增
def create_stack_layout(self):
# 创建堆叠（抽屉）布局
self.stacked_layout = QStackedLayout()
w1 = Window1()
w2 = Window2()
# 将2个添加到抽屉布局中
self.stacked_layout.addWidget(w1)
self.stacked_layout.addWidget(w2)Step 3: Add the relevant layout of the drawer interface
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.create_stack_layout()
self.init_ui()
def create_stack_layout(self):
# 创建堆叠（抽屉）布局
self.stacked_layout = QStackedLayout()
w1 = Window1()
w2 = Window2()
# 将2个添加到抽屉布局中
self.stacked_layout.addWidget(w1)
self.stacked_layout.addWidget(w2)
#————————————————————————————————————————————————————————————————
# 下面为新增
def init_ui(self):
self.setWindowTitle('form')
self.setFixedSize(500,400)
# 先定义最外层的垂直布局（水平布局是QHBoxLayout）
container = QVBoxLayout() # 最外层布局器（命名为容器）
self.setLayout(container) # 设置显示最外层布局器 (布局器的应用)
# 创建要显示的子widget
widget = QWidget()
widget.setLayout(self.stacked_layout)
widget.setStyleSheet("background-color:grey;")
# 创建2个按钮，用来点击进行切换抽屉布局中的weight
btn_press1 = QPushButton("界面1")
btn_press2 = QPushButton("界面2")
# 给按钮添加事件 （点击后调用的函数）
btn_press1.clicked.connect(self.btn_pres1_clicked)
btn_press2.clicked.connect(self.btn_pres2_clicked)
# 将需要显示的控件添加到布局中
container.addWidget(widget)
container.addWidget(btn_press1)
container.addWidget(btn_press2)Step 4: Click trigger for each drawer interface
First set the index value of the layout
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.create_stack_layout()
self.init_ui()
def create_stack_layout(self):
self.stacked_layout = QStackedLayout()
w1 = Window1()
w2 = Window2()
self.stacked_layout.addWidget(w1)
self.stacked_layout.addWidget(w2)
def init_ui(self):
self.setWindowTitle('form')
self.setFixedSize(500, 400)
container = QVBoxLayout()
self.setLayout(container)
widget = QWidget()
widget.setLayout(self.stacked_layout)
widget.setStyleSheet("background-color:grey;")
btn_press1 = QPushButton("界面1")
btn_press2 = QPushButton("界面2")
btn_press1.clicked.connect(self.btn_press1_clicked)
btn_press2.clicked.connect(self.btn_press2_clicked)
container.addWidget(widget)
container.addWidget(btn_press1)
container.addWidget(btn_press2)
#————————————————————————————————————————————————————————————————
# 下面为新增
def btn_press1(self):
# 设置抽屉布局当前的索引值（即可切换到指定的weight）
self.stacked_layout.setCurrentIndex(0)
def btn_press2(self):
# 设置抽屉布局当前的索引值（即可切换到指定的weight）
self.stacked_layout.setCurrentIndex(1)Second, the packaged drawer class
code:
class Window1(QWidget):
def __init__(self):
super().__init__()
QLabel("抽屉1内容", self)
self.setStyleSheet("background-color:green;")
class Window2(QWidget):
def __init__(self):
super().__init__()
QLabel("抽屉2内容", self)
self.setStyleSheet("background-color:red;")3. Program entry program
code:
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())4. Complete code
code:
import sys
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QLabel, QLineEdit, QDesktopWidget, QHBoxLayout, QVBoxLayout, QGroupBox, QRadioButton, QGridLayout, QFormLayout, QStackedLayout
class Window1(QWidget):
def __init__(self):
super().__init__()
QLabel("抽屉1内容", self)
self.setStyleSheet("background-color:green;")
class Window2(QWidget):
def __init__(self):
super().__init__()
QLabel("抽屉2内容", self)
self.setStyleSheet("background-color:red;")
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.create_stack_layout()
self.init_ui()
def create_stack_layout(self):
self.stacked_layout = QStackedLayout()
w1 = Window1()
w2 = Window2()
self.stacked_layout.addWidget(w1)
self.stacked_layout.addWidget(w2)
def init_ui(self):
self.setWindowTitle('form')
self.setFixedSize(500, 400)
container = QVBoxLayout()
self.setLayout(container)
widget = QWidget()
widget.setLayout(self.stacked_layout)
widget.setStyleSheet("background-color:grey;")
btn_press1 = QPushButton("界面1")
btn_press2 = QPushButton("界面2")
btn_press1.clicked.connect(self.btn_press1_clicked)
btn_press2.clicked.connect(self.btn_press2_clicked)
container.addWidget(widget)
container.addWidget(btn_press1)
container.addWidget(btn_press2)
def btn_press1_clicked(self):
self.stacked_layout.setCurrentIndex(0)
def btn_press2_clicked(self):
self.stacked_layout.setCurrentIndex(1)
if __name__ == '__main__':
app = QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())Example effect:
(interface 1)
(interface 2)
