How to capture a double click event on a QPlainTextEdit using signal and slot?

[gjiang]

I want to perform a text search operation when user double click a text in my QPlainTextEdit, but I can't find the doubleClicked signal in QPlainTextEdit class?
I seem someone mentioned using installEventFilter. I haven't tried that yet, and I prefer using signal and slot. Does anyone know how to do it?

Thanks in advance.

Hi @gjiang
The QPlainTextEdit is a QWiget. A QWidget has a double click event...

void QWidget::mouseDoubleClickEvent(QMouseEvent *event)

see the docs here maybe this will help.
