Informative dialog

[franco.amato]

Hi,
I would know if Qt provide an informative dialog. Something as wxWidget has.
Is not properly a dialog with button, is only a little window, without border and without buttons that informs the user of what is happenind.
For example...in my case I'm writing an audio editor and when user click a button the software encode part of the audio.
So I would run such dialog that "inform" the user of what's happening.

Something as:
creating output buffer
creating background sound
etc..

The text can change.
The dialog doesn't block the application, only inform and tasks still work.
I hope to be clear..
wxWidget fraemwork has exactly such dialog and the dialog is semi-transparent.

Best Regards,
Franco
