Question: I'm new in Qt and have a question.

I have `QLabel` and `QLineEdit` objects, and when `QLabel` text is clicked on, I want to set this text in `QLineEdit`.

Also I have read that `QLabel` has not clicked signal.

Can you explain how can I do this and write code for me ?!

Answer: 
Either style another type of QWidget such as a specific QPushButton to look like a QLabel and use its clicked() signal or inherit QLabel yourself and emit your own clicked() signal. 

See this example:
<https://wiki.qt.io/Clickable_QLabel>

If you choose the latter option you can pass the text in the signal. Then connect the necessary signals/slots up between the QLabel and the QLineEdit like so:

```
QObject::connect(&label, SIGNAL(clicked(const QString& text)),
                 &lineEdit, SLOT(setText(const QString& text)));

```
In the above example the header needs Q\_OBJECT:

class YourLabelClass : public QLabel{

Q\_OBJECT

signals:
