How to store the name of QlineEdit in a variable when its clicked?

Question

There is no signal as clicked for QlineEdit.

connect(w,SIGNAL(clicked()),this,SLOT());

Have you looked at [`focusInEvent`](http://doc.qt.io/qt-5/qlineedit.html#focusInEvent)? — m7913d, Jun 20 '17 at 14:19
Concerning `focusInEvent`, see [Event System](http://doc.qt.io/qt-5/eventsandfilters.html) for more information. An alternative is to use the [`textEdited`](http://doc.qt.io/qt-5/qlineedit.html#textEdited) or [`textChanged`](http://doc.qt.io/qt-5/qlineedit.html#textChanged) signals depending on what you really want. — m7913d, Jun 20 '17 at 14:52

There is no such signal in Qt widgets. You need to derive QLineEdit class and implement void QLineEdit::mouseReleaseEvent(QMouseEvent *e), like this:

class MyLineEdit public QLineEdit {
...
virtual void mouseReleaseEvent(QMouseEvent *e) { emit clicked(); }

signals:
void clicked();
}

Later, you can promote QLineEdit in graphical editor to MyLineEdit class.
