I presume the following is happening: the code in your show() 
method is executed within the main loop. This show()-method returns
after all of your modules are loaded. In other words, you are
blocking the main loop. After all is done, the main loop can 
continue work and paint the window.

You could load all your modules in a designated thread, which sends 
messages to the main thread whenever it's done something. The function 
that receives these notifications can display progress.

If you use the main thread to load your modules, the timeout will not be 
fired until your initialisation routine returns, i.e., when everything is 
done. Even if you break up initialisation into several atomic pieces, your 
application will be irresponsive while each of them runs.

Hope this helps,
