I see quite a few applications adopting a popup instead that collapses into
a toolbar icon showing a progress summary as a micro-pie-chart. And if you
need to disable access to some components in the main window, you can
disable/enable respective widgets depending on the progress. If the
operation really blocks everything, maybe put the progress controls into an
overlay widget parented by the main window, disabling actual main window
controls. If you still need the ability to move the progress dialog
independently of the main window, I'd suggest using a torn-off toolbar as a
container of progress controls.

Kind regards,
