Hi Marco,
The fill styles in the range 2000->2999 are reserved for a future
implementation. The only fill patterns currently supported are
in the range 3000->3100. These patterns are common to X11 and
Postscript.
The macro below draw these patterns.

//macro pattern.C
void pattern()
{
TCanvas *c1 = new TCanvas("c1","special fill patterns",600,500);
Int_t nx=5, ny=4;
c1->Divide(nx,ny);
Int_t i,j,pat;
TText t;
t.SetTextAlign(22);
t.SetTextSize(0.3);
t.SetTextColor(kRed);
char textpat[10];
pat = 4;
for (Int_t i=0;i<ny;i++) {
for (Int_t j=0;j<nx;j++) {
pat++;
c1->cd(i*nx +j +1);
gPad->SetFillColor(kBlue);
gPad->SetFillStyle(3000+pat);
sprintf(textpat,"%d",3000+pat);
t.DrawText(0.5,0.5,textpat);
}
}
c1->Print("pattern.ps");
gInterpreter->ProcessLine(".!gv pattern.ps");
}
