Here are some notes on using Qt on the Beagle.

Useful Links

  • The Qt site
  • Setting Up Qt Development Environment for BeagleBoard-xM has some nice instructions on getting QT going on the Beagle. It's set up for using Qt embedded. This writes directly to the framebuffer and doesn't need (and interferes with) X windows. I'm trying the following configure to make it work with the X11 version.
./configure -opensource -confirm-license -prefix /opt/qt-arm -no-qt3support -x11 -little-endian -xplatform qws/linux-DM3730-g++ -qtlibinfix E

I'm working through this example. I can't change mousearea1 to MouseArea to match the figure. I think something is missing in the instructions.

The Transitions section has some details missing:


   transitions: [
        Transition {
            from: "*"; to: "State1"
            NumberAnimation {
                properties: "x,y";
                duration: 1000
            }
        }
    ]

QWT

QWT is short for Qt Widgets for Technical Applications. It is a collection of widgets and support classes for creating technical applications such as those created using, for example, LabView or Test Point.

Here is some info on QWT. I think it might be able to plot data as it comes in.

Installs

Here's what I've installed on the Beagle

opkg install qt4-demos
opkg install linuxtag-ics
opkg install qt4-examples
opkr install qt4-x11-free qt4-x11-free-doc qt4-x11-free-dev
