The code you’re using as an example seem to work fine and looks quite clean. According to your comment your list widget is not getting initialized; this should be the root cause of your issue. I’ve simplified your code a bit a tried it on my Ubuntu 10.04LTS and it worked fine. My code is listed below, see if it would for you also. You should be able to drag and drop a file into the list widget; once it’s dropped a new item is added showing the image and image’s file name.
import sys
import os
from PyQt4 import QtGui, QtCore
class TestListView(QtGui.QListWidget):
def __init__(self, type, parent=None):
super(TestListView, self).__init__(parent)
self.setAcceptDrops(True)
self.setIconSize(QtCore.QSize(72, 72))
def dragEnterEvent(self, event):
if event.mimeData().hasUrls:
event.accept()
else:
event.ignore()
def dragMoveEvent(self, event):
if event.mimeData().hasUrls:
event.setDropAction(QtCore.Qt.CopyAction)
event.accept()
else:
event.ignore()
def dropEvent(self, event):
if event.mimeData().hasUrls:
event.setDropAction(QtCore.Qt.CopyAction)
event.accept()
links = []
for url in event.mimeData().urls():
links.append(str(url.toLocalFile()))
self.emit(QtCore.SIGNAL("dropped"), links)
else:
event.ignore()
class MainForm(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MainForm, self).__init__(parent)
self.view = TestListView(self)
self.connect(self.view, QtCore.SIGNAL("dropped"), self.pictureDropped)
self.setCentralWidget(self.view)
def pictureDropped(self, l):
for url in l:
if os.path.exists(url):
print(url)
icon = QtGui.QIcon(url)
pixmap = icon.pixmap(72, 72)
icon = QtGui.QIcon(pixmap)
item = QtGui.QListWidgetItem(url, self.view)
item.setIcon(icon)
item.setStatusTip(url)
def main():
app = QtGui.QApplication(sys.argv)
form = MainForm()
form.show()
app.exec_()
if __name__ == '__main__':
main()
hope this helps, regards
