使用 cef 在 tkinter 上设置框架 [英] Setting frames on tkinter with cef
问题描述
有人可以帮忙吗?
我用框架定义了我的页面，但是当我运行代码时，它只显示浏览器窗口.
I have my page defined with frames but when i run the code it only shows the browser window.
这个问题是在labelframe中加载CEF
它基本上是一个带有链接的窗口，右侧是一个浏览器窗口
Its basicly a window with links and a browser window on the right

推荐答案
请注意，更新 urlset 不会自动在 CEF 浏览器中加载 URL.您需要在 BrowserFrame 中创建一个函数来加载 URL:
Note that updating urlset will not load the URL in the CEF browser automatically. You need to create a function in BrowserFrame to load an URL:
# inside BrowserFrame
def open(self, url):
if self.browser:
self.browser.LoadUrl(url)
并且在创建 CEF 浏览器时需要加载一个默认 URL:
And you need to load a default URL when creating the CEF browser:
# inside BrowserFrame
def on_configure(self, event):
if self.browser is None:
...
self.browser = cef.CreateBrowserSync(cef_winfo,
url="https://www.google.com")
...
然后更新main()如下:
def main():
...
# specify initial width and height
browser = BrowserFrame(home_browser, width=1200, height=700)
browser.grid(row=2, column=0, columnspan=9, sticky="wn")
def choose_browser(urlbook):
if valido_browser.get() == 1:
webbrowser.open(urlbook)
else:
browser.open(urlbook)
# not necessary to call choose_browser() here
#choose_browser("http://www.google.com")
...
不建议像下面这样导入相同的模块:
It is not recommended to import same module like below:
from tkinter import *
import tkinter as tk
最好只使用后者.
