Hello I declared a field of type binary in my python file like this:

'nom_champ':field.binary('Importe fichier')

And in my xml file I declared the field as follows:

<field name="nom_champ"/>

At the interface I have two 3 buttons: "Select", "Save As" and "Empty".

The buttons work well. My only problem is that these buttons overlap. How do they not overlap? Is there attributes allow that? It seems to me that the "Select" button and "Save as" do the same thing. If yes how to eliminate one of them?

Basically how to get hold of these buttons?
