Intro
What is Maemo?
Few words about the maemo software platform

If you want to install the maemo SDK on your linux box this is the page that you want to check: SDK Releases
Porting a Qt application in Maemo

API changes
We don't want to break the API compatibility at all, but sometime we need to add some functions then to develop a Qt application in Maemo you can use the Official Qt 4.4 API Documentation and check the list below to know what are the API changes and additional info.
This is the list of the API changes.
bool QApplicationPrivate::areXInputEventsUsed(). Basically this functions returns true if the application runs on the device.
Other useful info about the API are:
QTableEvents are able to get the touchscreen info (Eg: pressure). - Touchscreen eventdeviceType is QTabletEvent::Stylus.
