Qpainter function on a QFrame problem

[impeteperry]

Hi
I now have my painter working on my laptop whereI compiled the program.
It also runs on my desk computer as long as I don't re-compile it there. If I re-compile the same source code there it locks up the computer on the first "p.drawText" command. I have single stepped the program on both computers. Everything is the same. There is no problem with the "p.drawLine" command. If I option out the single p.drawText(x, y, "text"); line 16, the program runs fine.

p.drawLine ( xs, ys, xe, ye );
						/// start of labeling.
				if ( tempList[4] == "true" )
				{
					xc = ( xs + xe ) / 2;
					yc = ( ys + ye ) / 2;
					if ( xs == xe ) angle = pi/2.0;
					else if ( ys == ye ) angle = 0.0;
					else	angle = atan((double)(ye - ys) / (double)(xe - xs));
					angle = ( angle * 180.0 ) / pi;
					p.save();
					p.translate ( xc, yc );
					p.rotate ( angle );
					p.scale ( 1, -1 );
					k = "S" + h.setNum ( n + 1 );
					p.drawText ( 0, 0, k );
					p.restore();
				}

p.drawLine ( xs, ys, xe, ye );
						/// start of labeling.
				if ( tempList[4] == "true" )
				{
					xc = ( xs + xe ) / 2;
					yc = ( ys + ye ) / 2;
					if ( xs == xe ) angle = pi/2.0;
					else if ( ys == ye ) angle = 0.0;
					else	angle = atan((double)(ye - ys) / (double)(xe - xs));
					angle = ( angle * 180.0 ) / pi;
					p.save();
					p.translate ( xc, yc );
					p.rotate ( angle );
					p.scale ( 1, -1 );
					k = "S" + h.setNum ( n + 1 );
					p.drawText ( 0, 0, k );
					p.restore();
				}

I am using the same Kubuntu 7.10 on each computer.
I am sorry to be such a pest.
Thanks for help.
