利用利用PyQt5实现窗口切换实现窗口切换
下面是一个小程序，利用PyQt5实现窗口切换，希望对大家有所帮助。
```python
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QPushButton,QDialog,QLabel
class main_windows(QWidget):
def __init__(self):
super(main_windows,self).__init__()
def setupUi(self,Form):
Form.setObjectName("Form")
Form.resize(500,500)
self.form = Form
self.btn1 = QPushButton(Form)
self.btn1.setGeometry(100,100,100,100)
self.btn1.setText("进入dialog1")
self.btn1.clicked.connect(self.slot_btn1_function)
def slot_btn1_function(self):
self.form.hide()
Form1 = QDialog()
first_Dialog = Dialog1()
first_Dialog.setupUi(Form1)
Form1.show()
Form1.exec_()
self.form.show()
class Dialog1(QWidget):
"""docstring for Dialog1"""
def setupUi(self,Dialog):
Dialog.setObjectName('Dialog')
Dialog.resize(500,500)
self.form = Dialog
self.btn1 = QPushButton(Dialog)
self.btn1.setGeometry(100,200,200,100)
self.btn1.setText('进入mian_windows')
self.btn1.clicked.connect(self.slot_btn1_function)
def slot_btn1_function(self):
self.form.close()
if __name__ == '__main__':
app = QApplication(sys.argv)
w = main_windows()
Form = QWidget()
w.setupUi(Form)
Form.show()
sys.exit(app.exec_())
具体效果见下图：
最核心的几句程序：
```python
self.form.hide()
隐藏原界面。
Form1.show()
显示新界面
