Gohar,

Below are two solutions with different characteristics:-

First,

plotObject[G_] :=
  Locator[{RandomReal[30], RandomReal[30]}, Graphics[G], ImageSize ->  
20]


Framed@Graphics[
   Table[{Arrow[{{RandomReal[30], RandomReal[30]}, {RandomReal[30],
        RandomReal[30]}}],
     plotObject[{RGBColor[RandomReal[1], RandomReal[1], RandomReal[1],  
0.5],
       Disk[{5, 5}, 5]}]}, {i, 10}], PlotRange -> 50]

gives black arrows which can be double clicked to move, resize &  
redirect each of them but are not Locators.

Second,

plotObject[G_] :=
  Locator[{RandomReal[30], RandomReal[30]}, Graphics[G], ImageSize ->  
40]

Framed@Graphics[
   Table[{plotObject[{RGBColor[RandomReal[1], RandomReal[1],  
RandomReal[1],
        0.5], Arrowheads[Large],
       Arrow[{{RandomReal[30], RandomReal[30]}, {RandomReal[30],
          RandomReal[30]}}]}],
     plotObject[{RGBColor[RandomReal[1], RandomReal[1], RandomReal[1],  
0.9],
       Disk[{5, 5}, 5]}]}, {i, 10}], PlotRange -> 50]

gives random coloured arrows which are locators which can be dragged  
but which cannot be resized or redirected.

HTH,

Cheers ... Syd
