how to break one long line of legend into two lines?

In the following legend, the 2nd line is too long to be held in the figure. Is it possible to break it into two lines?

     TLegend* lg0 = new TLegend(0.30,0.55,0.85,0.86, "", "NDC" );
     lg0->Draw();
     lg0->AddEntry(g1, "this analysis", "P" );
     lg0->AddEntry(g2, "some others result that was carried on many many 
years ago on something measurement, etc ", "P");
     lg0->AddEntry(g3, "theory#1", "L");
     lg0->AddEntry(g4, "theory#2", "L");
     lg0->SetTextSize(0.04);
     lg0->SetTextFont(42);
     lg0->Draw();

Thanks
