Re: [PyQt] QTreeWidgetItem.addChild() no longer keeping references

I noticed this because I often assign custom attributes to these items and found that the attributes go missing under 4.9.6 if I don't keep an explicit reference to the item. Here's an example from 4.8.3: from PyQt4.QtGui import * app = QApplication([]) tree = QTreeWidget() item = QTreeWidgetItem([Item]) item.attr = test tree.invisibleRootItem().addChild(item) del item import gc gc.collect() 0 tree.topLevelItem(0).attr 'test' ..and the same under 4.9.6: from PyQt4.QtGui import * app = QApplication([]) tree = QTreeWidget() item = QTreeWidgetItem([Item]) item.attr = test tree.invisibleRootItem().addChild(item) del item import gc gc.collect() 0 tree.topLevelItem(0).attr Traceback (most recent call last): File stdin, line 1, in module AttributeError: 'QTreeWidgetItem' object has no attribute 'attr' Questions are: 1) Is this a bug, or was the change deliberate? 2) Does this apply only to QTreeWidgetItem, or are there similar changes elsewhere I should watch out for? I think it's an old bug (specifically with invisibleRootItem()) exposed by a recent SIP fix. Fixed in tonight's PyQt snapshot.

Actually there are two. 1. configure.py doesn't detect, that the wrapper for QtWebkit should be built. 2. That left an old wrapper for QtWebkit in my installation directory, which caused the issue (a mix of compilations doesn't work). So I think, fixing 1. will get rid of 2 automatically. All this was done with Qt 5.0.1 on Linux (openSUSE 12.2) and Mac OS X Mountain Lion. Can you run configure.py with --verbose so that you can see why it doesn't think QtWebKit is available?

[PyQt] Are the older versions still available?
Source forge only goes back as far as 4.9.4 but I'm looking for an even older version (4.7.3-1, 4.8.3). Are they still available somewhere? Thanks ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
