1.新建Python项目使用QtDesigner设计界面使用PyUIC把设计的界面转换成py文件编写业务代码和Ui文件结合起来SetTextStyleMainWindow.pyimport sysfrom SetTextStyle import Ui_SetTextStylefrom PyQt5.QtWidgets import QMainWindow, QApplication, QCheckBox, QSpinBoxfrom PyQt5.QtGui import QPen, QPal

import sysfrom PyQt5.QtWidgets import QWidget,QApplication,QAbstractItemView,QMessageBox,QTableWidgetItemfrom PyQt5.QtCore import pyqtSlotfrom MySQL import Ui_MySQLfrom PyQt5.QtSql import QSqlDatabase,QSqlQueryModel,QSqlQueryclass NameTableItem(QTab.

import sysfrom PyQt5.QtCore import Qt, QRectfrom PyQt5.QtGui import (QPen, QPainter, QBrush, QColor,QLinearGradient)from PyQt5.QtWidgets import QWidget, QApplicationfrom Painter import Ui_Painterclass MyPainter(QWidget): def __init__(self,par.

使用QTimer做了一个计时工具import sysfrom PyQt5.QtWidgets import QWidget,QApplicationfrom PyQt5.QtCore import QTime,QTimerfrom Timer import Ui_Formclass TimerWgt(QWidget): def __init__(self,parent = None): super().__init__(parent) self.ui

先看效果：import sysfrom PyQt5.QtWidgets import QWidget,QApplicationfrom PyQt5.QtCore import pyqtSlotfrom Price import Ui_Formclass PriceMain(QWidget): def __init__(self,parent = None): super().__init__(parent) self.ui = Ui_Form()

先看一个实例：import sysfrom PyQt5.QtWidgets import QWidget,QApplication,QMainWindowfrom PyQt5.QtCore import pyqtSignalfrom Main import Ui_MainWindowclass MainWnd(QMainWindow,Ui_MainWindow): # 定义一个带有字符串类型的信号 sendStr = pyqtSignal(str) def __ini

Python可以通过调用Dll中的到处符号调用C++.新建一个QT的DLL项目：class MyMath {public: int add(int a, int b); int multiply(int a,int b);};extern "C" { QTPYTHONDLL_EXPORT int addEx(int a, int b); QTPYTHONDLL_EXPORT int multiplyEx(int a, int b); QTPYTHONDLL_EXPORT void

利用PyCharm创建一个PyQt程序1.新建一个QT界面设计完成之后，点击保存2.把UI文件编译成Py文件3.创建主程序文件，调用当前界面文件import sysfrom PyQt5 import QtWidgets, QtCoreimport Mainif __name__ == '__main__': app = QtWidgets.QApplication(sys.argv) mainWindow = QtWidgets.QMainWindow()

1.安装PyQt5直接连接服务器比较慢，可以连接镜像pip3 install -i https://https:pypi.tuna.tsinghua.edu.cn/simple PyQt52.安装pyqt5-tools安装镜像pip3 install PyQt5-tools -i http://pypi.douban.com/simple --trusted-host=pypi.douban.com3.配置QtDesignerQtDesigner用来设计程序界面由于我的电脑安装了Qt5.1
