Hi,
I think these are bugs but I'm not sure, so, in case I'm doing something
wrong, I'm emailing first. I am using Python 2.7.2, PySide 1.0.5, Qt 4.7.3,
and ArchLinux with kernel 3.0.3.
I'm porting an application from PyQt4, and the code works as intended
there. I'm trying to create a table by subclassing QAbstractTableModel and
using QTableView. When I minimally implement QAbstractTableModel (just
implementing rowCount, columnCount, data, headerData, and flags) the
resulting table is not how I would expect it to look (again, based on my
experiences with PyQt4).
First, each cell has a checkbox in it, even though I have not requested that
the cells be checkable, nor is the data boolean values. I cannot find any
setCheckable-like method to use with the model or view, and flags() never
includes Qt.ItemIsUserCheckable.
Second, if I call resizeColumnsToContents and resizeRowsToContents, then the
columns and rows are resized to the checkboxes and headers that are
displayed (even though I don't want checkboxes). However, the cell data,
even if it is very long, is not considered during the resize. Since the
headers are displayed, I can resize the rows and see that there is data to
the right of the checkboxes. Shouldn't the resize methods also consider the
cell contents?
If I use a QStandardItemModel instead of subclass a QAbstractTableModel,
then none of these problems appear. I'm not sure what goes into the
QStandardItemModel, however; perhaps it is calling some methods that I
should be calling during __init__?
I have attached a file that shows these two things when run as python2
table.py
Thanks in advance for any help with these issues, and great work with PySide
so far!
Ben
