[PyQt] Type information for signals
I'd rather like to be able to write code like this: for name in dir(obj): a = getattr(obj, name) if isinstance(a, QtCore.pyqtSignal): setattr(self, name, a) Unfortunately, signals of objects are of class pyqtBoundSignal and I can't find a class object to pass to isinstance - does it exist? For similar purposes of metaclass hackery, it would be useful to get the string form out of a signal object so that I can call functions like QObject.connectNotify and QObject.receivers ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Python Dict and QAbstractItemModel
hi all, i've a lot of difficulty for browser a standard python dictionnary withing a TreeListView, with QAbstracItemModel as model dictionnary isn't indexable, not trivial to find parent, etc... someone have try it or have an simple implementation example ?

Re: [PyQt] QTreeView DragDropMode (Copy vs. Move)
No problem, Bart. Thanks for replying. I think I am on the right track (a
right track) now. There seems to be many different ways to do what I am
trying to accomplish, but I haven't gotten the hang of quickly figuring out
the documentation and I am running out of time on this project. I think it
would have been quicker for me to do in HTML5, but we are stuck with IE7 on
these restricted machines. The one last thing I would like to do is have
this method remove the source row:
-
def dropMimeData(self, mimedata, action, row, column, parentIndex):
if action == Qt.IgnoreAction:
return True
dragNode = mimedata.instance()
print(mimedata : , dir(mimedata)) span
style='font-size:10.0pt;font-family:Courier New'
print(type = , mimedata.MIME_TYPE)
parentNode = self.nodeFromIndex(parentIndex)
# make a copy of the node being moved
newNode = deepcopy(dragNode)
newNode.setParent(parentNode)
self.insertRow(len(parentNode)-1, parentIndex)
self.emit(SIGNAL(dataChanged(QModelIndex,QModelIndex)),
parentIndex, parentIndex)
if (mimedata.hasFormat('compass/x-ets-qt4-instance')):
self.removeRow(row, parentIndex)
return True
---
The arguments(row, parentindex) here are obviously wrong, so I probably need
to override the drag event and change it to a move or something like that.

Re: [PyQt] Cannot 'configure' PyQt4.9 before build on Linuxmint
I got hit by this as well. Apparently having the correct sip in your path may not be enough. I have attached a script that properly builds sip+qt assuming you have downloaded the current tarballs. It also has the command that fails (SLED10-64/Ubuntu10-64) so Phil can take a look at it. Essentially: I had to specifically tell PyQt's configure where the sip include file (include/sip.h) was. sip -V 4.13.2 which sip .../sip-4.13.2/bin/sip python configure.py \ -q .../Trolltech/Qt-4.8.0/bin/qmake \ -e .../sip-4.13.2/include \ -v .../sip-4.13.2/share/sip Note that -e and -v are the same flags as how you configured sip which is how I figured this out in the first place (purely by serendipity, I copied the wrong configure flags in a shell by accident) I kind of think this might be a bug in the PyQt configure, but then I know all about configuration hell so I have some sympathy ( I had to patch Qt 4.8 to properly build WebKit on SLED10-64 as well ). I don't have sympathy for the amount of time it took me to figure this out though, so hopefully this will help future coders. :) Brian On 4/19/12 2:09 PM, murison muri...@alpheratz.net wrote: I, too, am stopped cold by this very same problem.

[PyQt] QPyNullVariant and bool()
Would it be logical to add a __nonzero__ method to QPyNullVariant which always returns False? I was going through a code of mine which broke with a new version of PyQt. I realized that it was because there is no __nonzero__ method in QPyNullVariant so bool(QPyNullVariant) is always True. Right now, if you use QVariant api 2, you can't check nicely (without typechecking) whether you get a nonzero value or Null/Falsy value. -- Deniz ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] QTreeView DragDropMode (Copy vs. Move)
When time is short I would say, add a method to the source model that you can call from the target model that removes the received items. That would make it work at least. It might even be the best way to do such a thing, but I'm not sure. It seems you handle the dragged in mimedata as the object coming from the source model. That doesn't seem right to me, you should serialise the information in the source models mimeData() method. This can be done in any way you like, so you could include sufficient information to describe the original node and remove it from the source model. -- Bart ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
