Hi,

i guess your loop is in one function inside your plugin.

The problem is, that you never return control to the Qt Mainloop where
the view updates are executed, as you stay in your loop.

The easiest way would be to create a QTimer in your plugin, that fires
at your desired frame rate and calls a function, only containing the
internal part of the loop. That way, the core will have the chance to
update the scene in between.

BTW, you can omit the updateView call. updatedObject already takes care
about the view update.

Best,
Jan Möbius
