[PyQt] enums and hand written code
Hi, I've got some hand written code using the SIP API to integrate PyQt with other C++ classes wrapped with another tool. I've got things generally working, but I'm not quite sure how to handle enums, such as Qt::AutoConnection. When I call api->api_convert_to_type(...) it asserts. I can do a sipTypeIsEnum(...) to check beforehand, but I don't see in the docs how to get the value out. Also, the docs should be updated to show how to get the sip api if its a PyCapsule. Thanks, Clint ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] pyuic4 problem
I downloaded a new version of PyQt and SIP and reinstalled. PyQt4
appeared to be installed properly, as was pyuic4. However when I ran
the following command:
david$ pyuic4 -d window.ui > window.py
I go this error message:

I don't understand what this means. Should I just delete all my python
files from the frameworks folder, and reinstall everything (a new
python install, etc)?

[PyQt] could this be a PyQt problem or it is Qt behavior change?
Hello, i have a QTableView with a QSortFilterProxyModel using a QSqlQueryModel as source, in Qt 4.5 i execute after the query has populated the data of the table resizeColumnsToContents() or resizeColumnToContent(int) and it get adjusted to the column contents but in Qt 4.6 if i have not reimplemented the sizeHint method in the delegate and i use the default QStyledItemDelegate.sizeHint method the col get not resized correctly, you can see an example here: http://img819.imageshack.us/img819/804/examplet.png I have printed to console the output of the sizehint of the delegate for the first visible col "SERIE" and row 0 and i get QSize(31, 15) in QT 4.6 and QSize(31, 16) in QT 4.5 but when i print the size of the section from the horizontal QHeaderView after the resize of the col i get 73 in Qt 4.6 and 46 in Qt 4.5, this col it is ever of three chars in all the rows of the model, the same three chars, so i don't understand why happens this difference, can anyone help me with this? Thanks. Regards, Miguel Angel. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
