QT 5 Will Be Available For Raspberry Pi

Posted by timothy on from the expectation-ratcheting-continues dept.

New submitter sirjohn writes with the good news that "A small group of ICS and Nokia engineers have started working on a minimal bootstrap to bring fully functional Qt 5" to the Raspberry Pi, writing "Do you want to create the next big thing on embedded devices and have $35 to invest? You can now have a complete development environment with accelerated graphics for basically nothing. I think it's a big deal ..." Plus, Nokia is funding 400 of the boards and looking for ideas (and developers) to use them. The competition is stiff; there are already quite a few impressive ideas listed.

    Qt 5 is about a *minimal* break in compatibility between Qt 4[1], so your suggestion of "breaking compatibility badly" was rather poorly researched.

    As for hating on moc... moc is not just for signals! I hear this sort of thing repeated time and time again, and it's clear that every time, people do not do their homework. When you can come up with a solution that can provide at least these capabilities, feel free to suggest it for Qt 6, and better still, offer a patch.

    - qobject_cast, a dynamic_cast which works across module boundaries (and doesn't use RTTI)
    - the meta object system, allowing you to introspect objects at runtime, think of something like C#'s reflection - take a look at things like QMetaObject[2] and QMetaMethod[3], etc.
        this includes runtime creation of instances of a given class, looking up a method by name and invoking it with random arguments, etc...
    - the properties system (Q_PROPERTY), allowing things like QML to set properties on C++ objects from javascript
    - signals and slots
