[Qt-interest] Loading gif animation on a qgraphicsview

[Andreas Unger]

Hello all,

I'm building a cross-platform application that must work consistently on
Windows and Linux OSes. I have a Qgraphicsview with a scene to which I add
and remove widgets. now some times, it takes long for the processing of all
the widgets to be loaded into the scene to take place, so I need to add an
animated gif to the scene such that while the other widgets are being
loaded, the user can get visual feedback that some processing is taking
place.

However, I'm at loss on how to do this, I can load an animated gif on a
Qlabel by doing qlabel->setMovie(QMovie *movie) but I can't have the
animation going while concurrently processing other gui events. What I first
tried to do is, when the user clicks a button, I start a new QThread that
emits a signal, and the main window has a slot which is connected to the
signal emitted by the thread and this slot starts the gif animation movie.
however, this doesn't work.

can someone please give me some tips or point me to some example source
code?

best regards,
Andreas
