webbrowser in Kivy

[Bronco0]

Hi,

How is it possible to create a web browser with Kivy?
I wanted to try with webkit python but uses Gtk or Qt, not possible to
integrate directly to Kivy.

I tried to use a Qt widget in a widget Kivy, but I have a problem with
the event loop.
Is there a way to disabled the loop and Qt to use than Kivy?

Thank you.

You can drive the Qt event loop by function calls, if you need to
(ie: if you have multiple frameworks that all want to run the event loop,
only one can really do it, so you have to drive the other manually..)

Are you trying to make a web browser, or just use webkit/etc to
render html to a display, to show a textfile or help box or something?

If its mostly just a display thing, you might be able to get away
with trying to render webkit to a framebuffer (or even to a texture and
then apply the texture in kivy?) ie: Like some of the video players work
.. use a widget in the toolkit (kivy in this case) and then find the
widget location and dimensions, then direct the webkit renderer to render
to framebuffer at that location/size; make it look like its in the UI, but
the UI is only aware of an empty box there.. that sort of trickery.

Hi,

It's actually possible, but working right now only on linux 64bits.

https://github.com/kivy/kivy-berkelium
Download the extension from https://github.com/kivy/kivy-berkelium/downloads

We have done an initial wrapper around berkelium.org project, even if
it's works mostly, it's linux only. Anybody wanna help / update the
project on the latest berkelium version is welcome !

Otherwise, you can use other toolkit (gtk, qt), but the main issue is
not to drive the main loop of both framework (that's the simple part),
the complex part is to be able to do the rendering of the framework in a
pixmap, put it in a texture, and use the texture for a Rectangle
instruction.

Hello lads!

I would like to ask about how is the work about porting webkit to kivy going? I picked an engineer project that requires multi-touch framework and a web rendering engine. Basically it would be a website editor/creator for a touchscreen devices. As a framework i picked Kivy for its simplicity. Now I would need an HTML rendering engine for it to work. Of course if there is another relatively simple framework with multi-touch support and a rendering engine that works with it, I'd be happy to change my used technologies. Also I could help to contribute with any rendering engine for Kivy, by supporting the team (of course I'm a not bad programmer).

Cheers,

Dracco

[SongHua Liu]

So is the web rendering engine thing solved?

I am also looking for a functionality as what Dracco said. Let's improve it. :)

On Android at least, a possible alternative but less platform independent way is to use web-views.  We're in the process of figuring out which Android widgets "just work."  There is plenty of support in pyjnius for making the API calls to Android.  There might be some code out there for showing a Maps widget.  Not sure what status is.

This guy posted an example of using a native webview, but I can't get it to work.

https://groups.google.com/forum/#!topic/kivy-users/9sH0y3KxCuU

He defines a simple widget that creates a webview. How do you load native widgets after they are created in pyjnius?

Ideas?

[Ahmad Alobaid]

1-copy the code to lets say we.py

2-import Webview to your main.py as a Widget, but note that it will take the whole screen (I tried to resize it with no luck)

I do not remember where did I got this code from, 

##in we.py

Hi,

Is there any other library by using which Browser can be developed on Kivy.
How about pywebview .

Can you give me pls an advice on how to make kivy to display a window with a specific web page?
 

[Boca Valentin]

I mean I want to use Kivy as a web browser.

if I understand correctly, your example simply opens a web page in the default browser (for example, Google Chrome).

I have already found a solution - cefpython, it works, at least on ubuntu.

Ok, now i understand what were you after. I had no idea of CefPython, thanks!
