QtPen draw wrong border for Rectangle (PyQt)
-
Hello everyone!
I try to draw the Rectangle:
@paint.setBrush(QtGui.QBrush(some gradient))
paint.setPen(QtGui.QPen(QtGui.QColor("black"), 1))
paint.drawRect(x, y, width, height)
@
as the result, this:!http://i60.tinypic.com/rhs8z5.jpg(sample)!
Why QPen border on top and on right side are shifted?
left and bottom border correct -
Hi,
You should give more information, like the complete painting code, PyQt/Qt/OS you are using.

Qt - 4.8.4
PyQt - 4.9.6
Windows 7As for you SGaist my friend, code as he is:
@
class Chart(QtGui.QWidget):
def init(self, parent=None):
super(Chart, self).init(parent)
def paintEvent(self, Event):
paint = QtGui.QPainter(self)
paint.setBrush(QtGui.QColor("#808080"))
paint.drawRect(40, 20, 580, 410)
paint.setPen(QtGui.QPen(QtGui.QColor("#ffffff"), 1))
grad = QtGui.QLinearGradient(0, 20, 0, 410)
grad.setColorAt(0.0, QtGui.QColor("#fefdc5"))
grad.setColorAt(1.0, QtGui.QColor("#f3c169"))
paint.setBrush(QtGui.QBrush(grad))
paint.drawRect(70, 430, 25, -100)
@I hope this will help

At last I understood myself (((
The problem occurs only if I'm trying to set (draw) a rectangle height from bottom to top using a negative value (drawRect(0, 0, 20, -100)).
If I set (draw) from top to bottom (drawRect(0, 0, 20, 100)) the rectangle looks perfect with no shifts.
Whyyyyyyyyyyyyyyyyyyyy???????????
