Answer 1

I am trying to build a arc with some text. I am able to create the arc and I can place the text along with curve. But so far I cant find a way ro rotate text perpendicular to the curve.
Here is the code I am trying
from __future__ import division
import os
import sys
from PyQt4 import QtGui,QtCore
import math

class PathPaintTest(QtGui.QFrame):

def __init__(self, *args):
super (PathPaintTest, self).__init__(*args)
self.setMaximumSize(250, 110)
self.setMinimumSize(250, 110)
self.setFrameShape(QtGui.QFrame.WinPanel)
self.setFrameShadow(QtGui.QFrame.Sunken)

def paintEvent(self, event):
hw = QtCore.QString("Hello World")
drawWidth = self.width() / 100
painter = QtGui.QPainter(self)
pen = painter.pen()
pen.setWidth(drawWidth)
pen.setColor(QtGui.QColor(QtCore.Qt.red))
painter.setPen(pen)
painter.translate(5,0)
cc1 = QtCore.QPointF(5, -15)
cc2 = QtCore.QPointF(220, -15)
