TArrow Class Reference

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();
