使用cef在tkinter上设置帧

Question

有人能帮忙吗

我用框架定义了我的页面，但当我运行代码时，它只显示浏览器窗口

本期是Load CEF in labelframe的延续

它基本上是一个带有链接的窗口，右边是一个浏览器窗口

Answer 1

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：

# inside BrowserFrame
def open(self, url):
    if self.browser:
        self.browser.LoadUrl(url)

创建CEF浏览器时，您需要加载默认URL：

# 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()，如下所示：

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：

from tkinter import *
import tkinter as tk

最好只使用后者
