How to apply QIntValidator for QTextEdit

[neel2818]

Hi All,

Is there any way to apply integer and real validator to QTextEdit widget ?
I have tried but i am not able to apply the QIntValidator to QTextEdit. For that i have to use QLineEdit.

Is there anyway i can apply integer and real validator in QTextEdit ?

Thanks,
Neel

What's wrong or unclear with the "example of use" in the [[Doc:QIntValidator]] docs?

This example validator is applied on QLineEdit that is applicable. But I am not able to apply validator on QTextEdit.

I could only solve in this way:
QString QTextEdit::toPlainText();
And after this I could use the validator.

Ah, sorry, I misread and confused TEXT edit with LINE edit.

I don't get the use case, though. The text edit widget is designed for multi-line, probably rich, text, whereas an integer or real number is only one line and would best fit into a line edit...

I guess your problem is that QTextedit does not have a setValidator method.
Why that is the case? Volker has given the answer. Multi-line may make it time consuming.
