Dear Tadeusz,
I always just use the editor from the canvas menu to create a pavelabel.
You can create the pavelabel with your text anywhere (i.e. somwhere in the
middle) on your canvas, and then move it with the mouse to wherever you
want.
If you want to get rid of the surrounding box, just right-click on the
box border and set the bordersize to 0.
To my opinion this is the most convenient way, but maybe our 'Guru Rene'
has even a more elegant way.
Cheers,
Nick.
