I'll just respond to the QtQuick issues. On Mon, 12 Mar 2012 01:57:12 ext Ariel Molina R. wrote: > Second observation: > After installing i tried the QML examples/particles from the git clone > dir (as they were not installed either) using the example launcher.
QML examples do not need to be built, but you didn't install anyways. To install, you use 'make install' after make. This doesn't work for all QML examples right now, but the issue is being actively worked on. > Observartions: > > 1.

Low framerate is common, because they were calibrated for visual impact instead of tailored to a specific (or even minimal) hardware configuration (I can assure you it looks great on my computer ;) ). For checking a more realistic qtquick performance case, try the non-particles examples (like the examples in the examples/quick folder, which demonstrate QtQuick 2.0 elements). 2-3. This is probably not expected behavior, but it's hard to tell given your inadequate description. For a useful bug report, I would recommend doing the following two things in the future: A) File it on bugreports.qt-project.org , the Qt Project bug tracker, instead of a mailing list. B) Clearly explain both the error and where the error occurs. "Low framerate" is hard to describe more accurately, and you specified what actions you took. However you did not clearly specify which example this was in. When observing the issue in an examples launcher, you need to specify which example was being shown by the launcher, or if the aberrant behavior was in the menu or wherever it was. Otherwise, it is impossible to be sure if the error has been reproduced, especially if it requires specific hardware to be made clearly apparent. -- Alan Alpert Senior Engineer Nokia, Qt Development Frameworks _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
