If you set a tooltip on something ( for example a trayicon ) it will look like this:

But if you go on Ubuntu at the clock ( and every tooltip on ubuntu general) that will be shown:

So is this a different type of a tooltip or something?

P.s
I am setting the tooltip with this:
Qt Code: 
  1. ui->Button->setToolTip("Start Operation");
To copy to clipboard, switch view to plain text mode
