Multithreading in GTKmm

["Zdravko Monov" <zdravko monov gmail com>]

Hi,
I am thinking of writing a multithreaded application in GTKmm. My
programm consists of a main window with a toolbar. Once a button from
the toolbar is clicked, an event is triggered. A thread should start.
This thread should take care of some user input - for example the user
clicks on another button from the toolbar - pretty much the same like a
media player controller. I guess I need some global volatile flag that
indicates whether the thread must be stopped? At several places the
initiated thread should check this flag - if it indicates 'STOP', then
the thread should stop. If the flag is 'PAUSE', the thread should pause
etc. Can you give me an advice for how to handle this situation in
GTKmm?
Best wishes
