Visualization entry Python programming interface embodied as shown in the code:
(1) Normal visual interface programming code entry:
SYS Import
the QWidget, the QApplication # introduced from PyQt5.QtWidgets import two classes procedural programming interface
IF __name__ __ == "__ main__":
# Create a class of Application
App the QApplication = (the sys.argv)
# create a window
w = QWidget ( )
# size setting window
w.resize (400,200)
# moving window
w.move (300,300)
# title of the window
w.setWindowTitle ( "PyQt5 have a desktop based application")
# display window
w.show ()
# static enter the main loop of the program, and to ensure the safety of the main loop by the end of the exit function
sys.exit (app.exec_ ()) # display window has a shape on the desktop
#QTdesigner and pyGUI expansion tool installed in the platform of pycharm and configuration
after installation directly # QT software or installation anaconda development environment will be installed on the computer a good QTdesigner.exe file, after which pycharm configuration file extension tool external tool, it can easily be started directly inside pycharm
In pycharm extended configuration tools inside and external toolQTdesigne pyGUI (ui file can be directly converted to .py file, establish categories of visual design interface direct calls)
After configuring step visual interface design are:
(1) using the expansion tool pychar inside QTdesigner visualization interface design, and save it as a file .ui;
(2) use pyGUI extension tool to design the converted file as a visual interface .ui .py file, generate a visual template categories established, you can call directly.
Specific code as follows:
import sys
import mainwinvertical #导入相应的设计好的QTdesigner主窗口的类，然后即可直接进行展示（由ui文件经过PYGUI扩展工具转换而来）
from PyQt5.QtWidgets import QApplication,QMainWindow
if __name__=="__main__":
app=QApplication(sys.argv)
mainwin=QMainWindow() #创建一个窗口
ui=mainwinvertical.Ui_MainWindow() #创建一个QTdesigner的类
ui.setupUi(mainwin) #将对象直接进行运行设置函数，向主窗口上添加控件
mainwin.show() #展示出来窗口的形式
sys.exit(app.exec_()) #承接开头语句，用来实时的显示窗口
其中mainwinvertical类的具体代码如下：（由QTdesigner设计好可是换界面，然后直接用pyGUi扩展工具转换为.python代码文件）
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'mainwinvertical.ui'
#
# Created by: PyQt5 UI code generator 5.13.2
