I'm investigating whether it is possible to implement QPaintEngine in
Python, but I have a problem with my test program:
-----------------------------------------------
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys
class PaintEngine(QPaintEngine):
def begin(self, paintdevice):
self.paintdevice = paintdevice
return True
def drawLines(self, lines, count):
print count, lines
def end(self):
return True
class PaintDevice(QPaintDevice):
def __init__(self):
QPaintDevice.__init__(self)
self.engine = PaintEngine()
def paintEngine(self):
return self.engine
app = QApplication(sys.argv)
device = PaintDevice()
p = QPainter(device)
p.drawLines( [QLineF(0, 0, 100, 100), QLineF(100,100,200,200)] )
p.drawLine( QLineF(200,200,300,300))
----------------------------------------------
This outputs:
2 PyQt4.QtCore.QLineF(0.0, 0.0, 100.0, 100.0)
1 PyQt4.QtCore.QLineF(200.0, 200.0, 300.0, 300.0)
As far as I can see, from the C++ API the first call to drawLines should
pass a list of two QLineF objects, but only one is received.
The C++ documentation says:
void QPaintEngine::drawLines ( const QLineF * lines, int lineCount )
but the PyQt documentation says:
QPaintEngine.drawLines (self, QLineF lines, int lineCount)
Shouldn't lines be a list of QLineF objects? is this a mistake in the
bindings or am I doing something wrong?
Thanks
Jeremy
