Python - Showing a web browser/iframe right into the app

问题

I have a script which if helpful to people answering questions, is using kivy. I want to have it show a iframe kind of thing right into it when run, instead of opening the browser. For example something like this:

def browser():
    url = "google.com"
    iframe(url)
browser()

Obviously this wouldnt work as python is not html. Keep in mind, I am not trying to run this script on the web, but on the kivy launcher. As intended, it should not open the webbrowser but instead show the page in a box built right into the script.

You are trying to do this on an android device? There's currently not a build in way to do this, but I'm pretty sure it's possible to load a native android webview via pyjnius. I'm not sure the current state, but for example here is an example of how to do it. I've pasted some of the code below, but I recommend asking on the kivy mailing list or irc if you have any questions, as this kind of thing is under discussion and development.

from android.runnable import run_on_ui_thread

WebView = autoclass('android.webkit.WebView')
LayoutParams = autoclass('android.view.ViewGroup$LayoutParams')
activity = autoclass('org.renpy.android.PythonActivity').mActivity

class Wv(Widget):
    def __init__(self, **kwargs):
        super(Wv, self).__init__(**kwargs)
        self.create_webview()

    @run_on_ui_thread
    def create_webview(self):
        webview = WebView(activity)
        activity.addContentView(webview, LayoutParams(-1, -1))
        webview.getSettings().setJavaScriptEnabled(True)
        #having some trouble with this one: webview.setBackgroundColor(Color.TRANSPARENT)

        html = "<html><body style='margin:0;padding:0;'>\
            <script type='text/javascript'\
            src='http://ad.leadboltads.net/show_app_ad.js?section_id=ID_HERE'>\
            </script></body></html>"    

        activity.setContentView(webview)
        webview.loadData(html, "text/html", "utf-8")
        layout = LinearLayout(activity)
        layout.addView(activity.mView)
        activity.setContentView(layout)

Here's an actual running example which works right inside the "Kivy Launcher" app:

import kivy                                                                                     
from kivy.app import App                                                                        
from kivy.lang import Builder                                                                   
from kivy.utils import platform                                                                 
from kivy.uix.widget import Widget                                                              
from kivy.clock import Clock

from android.runnable import run_on_ui_thread                                                   

WebView = autoclass('android.webkit.WebView')                                                   
WebViewClient = autoclass('android.webkit.WebViewClient')

class Wv(Widget):                                                                               
    def __init__(self, **kwargs):                                                               
        super(Wv, self).__init__(**kwargs)                                                      
        Clock.schedule_once(self.create_webview, 0)

    def create_webview(self, *args):                                                            
        webview = WebView(activity)                                                             
        webview.getSettings().setJavaScriptEnabled(True)                                        
        wvc = WebViewClient();

        activity.setContentView(webview)

    ServiceApp().run()
