Qt how to open Device Manager

I am trying to open device manager from a button on Qt Windows app.

What I tried: Assigned the slot/signal to the button. And the method:

 QProcess *proc = new QProcess(this);
    QString cmdStr = "devmgmt.msc";
    proc->start(cmdStr);
    qDebug() << "btn clicked";

But nothing happens when I click it. btn clicked is displayed in console tho.

Edit: I tried also

cmdStr="mmc devmgmt.msc"

But also unable to open.

Solution

  • Ok managed to get it to work by using QDesktopServices.

    QDesktopServices::openUrl(QUrl("file:///C:/Windows/System32/devmgmt.msc", QUrl::TolerantMode));
