Project description

tkwebview2

tkinter浏览器-网页组件,tkwebview2登场!!!

基于pythonnet-webview绑定和WebView2.Core,将受到微软WebView2的持续改进支持,外观和效能相比tkinterie得到大幅度改进。

依赖

以下是tkwebview2的依赖库:

  • pythonnet(clr)
  • pywebview(webview)

使用方法

WebView2(master,width:int,height:int,url:str='',**kw)
'''
master::父组件
width::初始宽度
height::初始高度
url::网址或html文件,可以为空
**kw::其它Frame参数
'''

例子:

from tkinter import Tk
from tkwebview2.tkwebview2 import WebView2

root=Tk()
root.title('pywebview for tkinter test')
root.geometry('1200x600+5+5')

frame=WebView2(root,500,500)
frame.load_html('<h1>hi hi hi</h1>')
frame.pack(side='left')

frame2=WebView2(root,500,500)
frame2.load_url('https://smart-space.com.cn/')
frame2.pack(side='right',fill='x',expand=True)

root.mainloop()

方法

get_url()

返回当前url。

evaluate_js(self,script)

执行JavaScript代码,并返回最终结果。

load_css(self,css)

加载CSS样式。

load_html(self,content,base_uri=None)

加载HTML代码,base_uri为基本URL,默认为本程序启动目录。

load_url(self,url)

加载全新url。


判断WebView2 runtime是否存在并处理

tkwebview2提供了两个函数:have_runtime, install_runtime

have_runtime()

判断运行环境是否存在,存在返回True,不存在返回False。

from tkwebview2.tkwebview2 import have_runtime

print(have_runtime())

install_runtime()

下载并安装运行环境。

from tkwebview2.tkwebview2 import have_runtime, install_runtime

if not have_runtime():
    install_runtime()

注意:该函数会暂停程序运行,直到安装界面被用户手动关闭。期间,会下载安装程序到D盘,安装完成后会自动删除。
