Building QT Base

Because the QT package shipped with Raspbian doens't come with all dependencies, we need to ship a separate version with the WebView.

At the moment, this build will not work with cross-compiling, and needs to be done on a Raspberry Pi.

Start by building the base image:

$ docker build -t qt-builder .
[...]

With the base image done, you can build QT Base with the following command:

$ docker run --rm -ti \
    -v $(pwd)/build:/build -ti qt-builder

This will output the files in a folder called build/ in the current directory.

Usage

DBus is used for communication. Webview registers screenly.webview object at /Screenly address on the session bus.

Webview provides 2 methods:loadPage and loadImage.

Example of interaction (python):

from pydbus import SessionBus

bus = SessionBus()
browser_bus = bus.get('screenly.webview', '/Screenly')

browser_bus.loadPage("www.example.com")
