$FileDir$

4、 test

（1） Create a new one Pycharm engineering , Select the project directory , Other defaults will do .
And then through Pycharm In the menu bar Tools->External Tools, Choose the configured QtDesigner, start-up designer.

（2） stay designer Create a new one in Wdiget：

（3） Through the left sidebar , Select the drag method and drag it to the work window , add to Lable、pushButton：

（4） Then save to the project location , Save as test.ui.

（5） Switch to Pycharm, Found under the project directory test.ui file , Right click the file , And select PyUIC convert , Here's the picture ：

After successful execution , You'll find out that there's a test.py file , This document is ui Converted py file

（6） Call the UI, stay main.py（main.py It is the file generated by default when creating the project ） Delete the original code in the file , And enter the following code to call ：

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication

import test

#######################  Global variables #########################
app = QApplication(sys.argv)
num = 0


class MyWindows(test.Ui_Form, QMainWindow):
    def __init__(self):
        super(MyWindows, self).__init__()
        self.setupUi(self)
        self.label.setText("click:{}".format(num))


my_windows = MyWindows()  #  Instantiate objects 
my_windows.show()  #  Display window 


####################### button click #########################
def button_click():
    global num
    num += 1
    my_windows.label.setText("click:{}".format(num))


my_windows.pushButton.clicked.connect(button_click)

sys.exit(app.exec_())

（7） Right click execution main.py, Here's the picture ：

Test success ！
