Draw all kinds of Arrows.

The different arrow's formats are explained in TArrow::TArrow. The picture below gives some examples.

Once an arrow is drawn on the screen:

One can click on one of the edges and move this edge.
One can click on any other arrow part to move the entire arrow.

 
void arrows(){
   TCanvas *c1 = new TCanvas("c1");
   c1->Range(0,0,1,1);
 
   TPaveLabel *par = new TPaveLabel(0.1,0.8,0.9,0.95,"Examples of various arrows formats");
   par->SetFillColor(42);
   par->Draw();
 
   TArrow *ar1 = new TArrow(0.1,0.1,0.1,0.7);
   ar1->Draw();
   TArrow *ar2 = new TArrow(0.2,0.1,0.2,0.7,0.05,"|>");
   ar2->SetAngle(40);
   ar2->SetLineWidth(2);
   ar2->Draw();
