[PyQt] Is it possible to override/extend QTextCursor?

[Aaron Digulla]

Hello,

I tried to overload insertText() of QTextCursor like this:

------------------------------------------------------------
from PyQt4.QtGui import QTextEdit, QTextCursor, QApplication
import sys

class MyCursor(QTextCursor):
    def __init__(self, doc):
        super(MyCursor, self).__init__(doc)

    def beginEditBlock(self):
        print 'beginEditBlock'
        super(MyCursor, self).beginEditBlock()

    def insertHtml(self, text):
        print 'insertHtml',repr(text)
        super(MyCursor, self).insertHtml(text)

    def insertText(self, text, format=None):
        print 'insertText',repr(text)
        super(MyCursor, self).insertText(text, format)

app = QApplication(sys.argv)

edit = QTextEdit()
cursor = MyCursor(edit.document())
edit.setTextCursor(cursor)

edit.append('x')

print edit.toPlainText()
------------------------------------------------------------

but this test only outputs "x". I've checked the C++ source of Qt4 and
it should call at least the methods defined above.

I'm using openSUSE Linux and python-qt4 4.3-19. The methods are defined
in qtextcursor.sip, only insertText() is confusing:

    void insertText(const QString &text);
    void insertText(const QString &text, const QTextCharFormat &format);

Which one will Python overload?

Any ideas what could be wrong?

Thanks a lot,
