Hi,
I'm new to this list so I apologize if this has been asked / reported
before. I'm trying to add drag n' drop support to a QListWidget. Here
is my current test code:
------------------------------------------------------------------------------
from PyQt4.Qt import *
class ListWidget(QListWidget):
def __init__(self, parent=None):
QListWidget.__init__(self, parent)
self.setAcceptDrops(True)
self.startPos = QPoint();
def mousePressEvent(self, event):
if event.button() == Qt.LeftButton:
self.startPos = event.pos()
QListWidget.mousePressEvent(self, event)
print "mPE - Pos: %dx%d" % (self.startPos.x(), self.startPos.y())
def mouseMoveEvent(self, event):
if event.buttons() & Qt.LeftButton:
print "mME - Pos: %dx%d" % (self.startPos.x(), self.startPos.y())
------------------------------------------------------------------------------
While the app is running, I left-click on my "ListWidget" and then
(while holding the button clicked) move my mouse. The output looks
like:
mPE - Pos: 56x257
mME - Pos: 137x129
mME - Pos: 149x105
mME - Pos: 155x87
mME - Pos: 159x75
mME - Pos: 161x67
mME - Pos: 163x57
mME - Pos: 165x49
mME - Pos: 165x48
[...]
I don't understand why self.startPos keeps changing whenever I move
the mouse ?! Am I doing something wrong or is there a bug somewhere in
Python / SIP / PyQt / Qt ?
I'm running the following software versions (under ArchLinux):
- python 2.5.2
- qt 4.3.3
- sip 4.7.3
- pyqt 4.3.3
Thanks for your help.
Regards,
Gilles.
