[Qt-interest] Asynchronous loading?

[Christopher Rasch-Olsen Raa]

Hi,

I have an application that consist of a QTabWidget. Each of the tabs have a 
widget that have to fetch a fair amount of data from an external database. At 
the present time the program takes a lot of time to start because of all of 
them getting stuff at the same time.

What I'd like to see happen is that the program first loads the data for the 
active tab, and then proceeds to load data for the other "hidden" ones. Do you 
have any pointers on how to implement this somewhat cleanly without blocking 
the GUI?

Oh, and btw; at the present time the loading happens in the constructor of the 
various widgets placed in the QTabWidget. It's no problem changing this.
