【PyQt5-Qt Designer】PyQt5+pyecharts 实现GUI界面的数据可视化展示

先用纯Python代码写一个简单的小案例：

 

from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication,QWidget,QHBoxLayout,QFrame
from PyQt5.QtWebEngineWidgets import QWebEngineView
import sys

class Stacked(QWidget):
    def __init__(self):
        super(Stacked, self).__init__()
        self.initUI()
        self.mainLayout()

    def initUI(self):
        self.setGeometry(400,400,800,600)
        self.setWindowTitle("demo1")

    def mainLayout(self):
        self.mainhboxLayout = QHBoxLayout(self)
        self.frame = QFrame(self)
        self.mainhboxLayout.addWidget(self.frame)
        self.hboxLayout = QHBoxLayout(self.frame)
        self.myHtml = QWebEngineView()
        url = "http://www.baidu.com"
        #打开本地html文件
        self.myHtml.load(QUrl("file:///D:/360Downloads/Python编程/数据分析+数据可视化/pyecharts/PyQt5+pyecharts/bar1.html"))
        # self.myHtml.load(QUrl("bar1.html"))   #无法显示，要使用绝对地址定位，在地址前面加上 file:/// ，将地址的 \ 改为/
        #打开网页url
        # self.myHtml.load(QUrl(url))
        
        self.hboxLayout.addWidget(self.myHtml)
        self.setLayout(self.mainhboxLayout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Stacked()
    ex.show()
    sys.exit(app.exec_())

案例2：使用Eric6-Qtdesigner完成界面，再重写事件响应

效果如下：

ps:

　　用的结构是左边一个QListWidget + 右边QStackedWidget，将QWebEngineView加在QStackedWidget里面的QFrame里面（用的pyecharts做的数据可视化 生成的html文件，直接嵌入在GUI界面中）

注意：

PyQt5 最新版本之后统一使用 ： 

from PyQt5.QtWebEngineWidgets import QWebEngineView

试了很多次 QStackedWidget.addWidget(self.browser)  总是出错，故在QStackedWidget 里面嵌套了一个QFrame，再把self.browser 添加到QFrame里面

解决 No module named PyQt5.QtWebKitWidgets
原因：在 PyQt 5.6(+) 版本中, 新增 QtWebEngineWidgets 代替QtWebKitWidgets。
