Set default mouse!

Hi all,
I use geant4 OpenGL QT ui,
the default mouse action is rotate, could I set it to Move or others?

Right-click in the viewer window to get a pop-up menu that allows you to change mouse function.

Actually, shift-move pans/translates - just hold down the shift key.

Founded from the source using G4UIExecutive

dynamic_cast<G4UIQt*>(ui->GetSession())->SetIconMoveSelected();

Not sure what you mean.

I just want to change the default mouse function in the code when I open UI without using mouse Right-click.
