[PyKDE] Progress of QTextEdit in PyQt4

[Andreas Pakulat]

Hi,

what's the current status of the QTextEdit support in PyQt4?

I found that copying and pasting in a Plain text QTextEdit changes from
bold-italic Font to italic Font for the inserted text. The same for cut
and drag and drop.

The second more serious thing is, that it seems QTextEdit's support for
Rich Text is not done? I get a segfault when trying to use a
QTextTableFormat with it:

textedit = QtGui.QTextEdit()
cursor = self.textedit.textCursor()
tableFormat = QtGui.QTextTableFormat()
tableFormat.setBorder(1)
tableFormat.setCellPadding(16)
tableFormat.setAlignment(QtCore.Qt.AlignRight)
cursor.insertTable(1, 1, tableFormat)

This is from the dockwidgets example. The backtrace from gdb is at the
end of this mail. Sorry for the lengthy output.

This is with PyQt4 snapshot 20051222, I'm building PyQt4 snapshot
20051224 right now (though from the Changelog I doubt it will change
anything).

Andreas
