Lightweight Python Web Browser
I'd use PyQT to display the page but if the way PyQT use threads does not fit within you application, you may just write a minimalist (I'm speaking of ~10 lines of code here) web browser using PyQT, and fork it from your main application ?
Got a bit of weird request here, however it's one which I can't really figure out the answer to.
I'm writing a python application that displays web pages and locally stored images. 
What I need is a way of displaying a web page using python that is really lightweight and quite fast. The reason for this is that it is running on a Raspberry Pi.
Of course I have many options, I can run it through web browser installed on the Raspbian distribution and run it as a separate process in python, I can download an Arch-Linux compatible browser and run it as a separate process in python and finally I can write my own native python file using Gtk or PyQt. 
All of these approaches have their downsides as well as serious overheads. The web browser must also be full screen when I have a web page to display, and minimised when I'm displaying an image. 
The main issue I have had with Gtk and PyQt is the way they have to be executed on the main thread - which is impossible as it doesn't align with my multithreaded architecture. The downside to using the web browsers that are pre-installed on raspbian, is that from python you lack control and it's slow. And finally, the issue with using an Arch-Linux browser is that it ends up being messy and hard to control.
What I would Ideally need is a web browser that loads a web page almost instantaneously, or a multithreaded web browser that can handle multiple instances. This way I can buffer one web page in the background whilst another browser is being displayed.
Do you guys have any advice to point me in the right direction? I would've thought that there would be a neat multithreaded python based solution by now, and I would think that's either because no one needs to do what I'm doing (less likely) - or I'm missing something big (more likely)!
Any advice would be appreciated.
James.
