[Qgis-user] Re: Overview (inset map ) in map composer

[Andreas Neumann]

Hi Lionel,

Do you mean a zoom-rectangle in the selected map view?

I usually set the map scale to some round value (I don't like map scales
that are not rounded). This sets the zoom value for me. Then you can
change the map extent by dragging the map content.

Are you aware that you can also zoom with the mouse wheel in the map in
the print composer? Given this functionality - do you still think that the
zoom rectangle is necessary?
