How to open a .txt file directly by clicking on a label

FranciscoSantiago

Hi all,
maybe this is a stupid issue, but I've been searching the solution on Internet since two hours and now I'm fed up and I ask to you.

I have a Qlabel. When I click it (by using the slot linkActivated I suppose) I want to directly open a .txt file in my PC.

Is this doable? Who can help me? Please let me know the proper instructions.

Yes you can do this with QDesktopServices::openUrl.

Hi, Thank you for reply.
Could you be more precise? Have you got an example ?

How can I set the label, link, url, QDesktopService, and so on... ?

Thank you ;)

QLabel* label = new QLabel("<a href=\"file:///path/to/my/local/file\">Any text or file path</a>");
connect( label, SIGNAL(linkActivated(QString)), this, SLOT(onLabelLinkClicked(QString)) );
...
void onLabelLinkClicked(const QString & link)
{
      QUrl url = QUrl::fromUserInput(link);
      if( url.isValid() )
          QDesktopServices::openUrl(url);
}
