* This class is the one used to show informations to users.
* "information" is a common term to say "something users should know about", it can be
* informational, a warning or a critical error (\sa Icon).
*
* Here is an example on how to use it in combination with the AssumaEffect class :
* \code
* AssumaPassivePopup *popup = new AssumaPassivePopup(this);
* popup->setText(str);
* AssumaEffect *effect = new AssumaEffect(0,popup, AssumaEffect::SLIDE_FROM_BOTTOM);
* connect( popup, SIGNAL( closeButtonClicked() ), effect, SLOT( reverseEffect() ) );
* connect( effect, SIGNAL( AssumaEffectFinished() ), popup, SLOT( close() ) );
* effect->setTimeBeforeReversing( popup->timeToShow() );
* effect->doEffect();
* \endcode
