PyQT Problems

[jacek]

How can i read the Content of a QTextEdit Widget line by line and how can i write it in line by line?

To append a line you can use QTextEdit::append(). Reading line by line is a bit more complex, but you can get all of the text with QTextEdit::toPlainText() (the docs are for C++ version, but PyQt behaves almost the same).

How can i read out the content of a QLineEdit Widget?

See QLineEdit::text() and QLineEdit::setText() methods.

How can i set and Read out the Date of a QDateEdit Widget?

See QDateTime::date() and QDateTime::setDate() methods.
