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
- This looks like a nice reference.
- Building Qt to make use of the Beagle board’s SGX GPU
- Building Qt from TI's site
- Embedded Linux Qt
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
