[SOLVED] How can a label be linkable not to a website but to a void funtion of the program?

Leon

Well even if i dont assign it by UI but create it with ur code it's the same error about the emit not beeing declared..

In that case I don't know, it works for me, emit is the standard Qt keyword to emit a signal. Do you have the Q_OBJECT macro in the header of MyLabel as in my example?

There is no need to subclass QLabel.

Just set "openExternalLinks":http://qt-project.org/doc/qt-5.0/qtwidgets/qlabel.html#openExternalLinks-prop to false on connect to the "linkActivated":http://qt-project.org/doc/qt-5.0/qtwidgets/qlabel.html#linkActivated signal.
@
ui->label->setOpenExternalLinks(false);
connect(ui->label, SIGNAL(linkActivated(QString)), this, SLOT(label_clicked(QString)));

void MainWindow::label_clicked(const QString &link)
{
if (link == "...") ...
}

The text SHOULD be in "Rich text" , AFAIK.

I know that.. You click change rich text in the designer and there is a button "Insert link".

What should i put there when i want the label_clicked void to be called..?

Whatever you like.

@
ui->label->setText("This is text with a <a href='someLink'>link</a>.");

void MainWindow::label_clicked(const QString &link)
{
if (link == "someLink") ...
}
