Make sure you use qclone rather than clone.
I ran dip-builder, and
when I tried to make a distutils distribution, I got the following:
File
/home/darren/.local/lib/python2.6/site-packages/dip/ui/toolkits/qt/qlistwidget_editor.py,
line 234
rows = list({index.row() for index in indexes})
^
SyntaxError: invalid syntax
I don't think set comprehensions are available in python2.
Should be fixed now.
Note that dip snapshots are updated on a push rather than being done
overnight. Other packages will be moved to this behaviour over time.
Thanks,
Phil

Oh, sorry. You were right, I overlooked qclone.

It is. Thanks.

[PyQt] pyqt treewidget and multiselection/drag selection event?
Hi there, first post to this mailing list :) Im having real issues with getting my treewidget to behave how i need, im hoping someone can point me in the right direction. Ok so I have a GUI that is heavily based on the QtGui.QTreeWidget. I have set this how i need with the itemClicked method. i.e I select an item, it selects all children items, changes the childrens icons, deselects the all parent items and changes the parents icons. That bit is working great. But I want to replicate the same functionality when people drag/multi select the items with one mouse press/move. I tried using the itemEntered method, but seems to be unpredictable due to the children selection changes. So is there a way to know when a drag/multi selection has occurred, im unsure of how to make a custom event todo this? If i could catch all items selected I can run my set up in a for loop quite easily. Any help would be great.

[PyQt] Preview of a QtGraphicsItem
Hi all, I'm developing a cad application with pyqt: PythonCad I get some truble(crash,Sometimes the line is not rendered,..) creating a preview system for rendering the QtGraphicsItem during the command execution. I follow this steps to create the preview. When the user execute a command es: Segment. I create a QtGraphicsItem, and I grap the mouse moveevent for updating the line . So when the user change the mouse position the line is updated. There is any more smart way to do such a thing, any idea,..?

The book is aimed at C++/Qt programmers and covers ideas and techniques that are too advanced or specialized (but not necessarily difficult) for a first book on Qt. I believe that this book will be helpful and useful to PyQt4 programmers who have a basic familiarity with C++ since most of the Qt techniques shown apply equally to C++ and PyQt4.

[PyQt] Trigger mouse click on arbitrary coordinate using Webkit?
Hi, I'm using Qt Webkit to load a a webpage and interact with it. Is there a way to programmatically trigger a mouse click given the X, Y coordinates of a webpage? So far, I was able to use QWebFrame.hitTestContent(QPoint) to get the QWebElement under the given QPoint. However, the element is a Flash object, and I'd like to trigger a mouse click somewhere on that Flash object. Any suggestions?

[PyQt] Issue with pyqtSlot(QModelIndex, QModelIndex)
Dear list,
I've just upgraded from PyQt 4.6 (PyQt-Py2.6-gpl-4.6-1.exe) to version
4.7.4 (PyQt-Py2.6-gpl-4.7.4-1.exe), and the upgrade introduced a crash
in my program. I've narrowed it down to this example:
from PyQt4 import QtCore, QtGui
class Dialog(QtGui.QDialog):
def __init__(self, parent=None):
QtGui.QDialog.__init__(self, parent)
self.resultsModel = QtGui.QStandardItemModel()
self.resultsModel.appendRow(QtGui.QStandardItem('Item 1'))
self.resultsModel.appendRow(QtGui.QStandardItem('Item 2'))
self.resultsModel.appendRow(QtGui.QStandardItem('Item 3'))
self.layout = QtGui.QVBoxLayout(self)
self.resultsView = QtGui.QTreeView(self)
self.resultsView.setModel(self.resultsModel)
self.layout.addWidget(self.resultsView)
smodel = self.resultsView.selectionModel()
smodel.currentChanged.connect(self.on_change)
@QtCore.pyqtSlot(QtCore.QModelIndex, QtCore.QModelIndex)
def on_change(self, current, previous):
print 'Changed from %s to %s' % (previous.row(), current.row())
app = QtGui.QApplication([])
win = Dialog()
win.show()
app.exec_()
The program crashes with this error:
Traceback (most recent call last):
File qttest.py, line 26, in module
win = Dialog()
File qttest.py, line 19, in __init__
smodel.currentChanged.connect(self.on_change)
TypeError: on_change() has no overload that is compatible with
currentChanged(QModelIndex,QModelIndex)
When I remove the @QtCore.pyqtSlot() decorator the code runs just
fine. It's a workaround, but I would prefer a clearner solution, or at
least an understanding as to the cause of the exception.
The exception occurs when running on PyQt 4.7.4, Qt 4.6.2 and Python
2.6 on Windows XP.
The same code runs without error on PyQt 4.7.3, Qt 4.6.3 and Python
2.6 on Ubuntu Linux.
