Shortcut QLineEdit

[A Former User]

I need created shortcut grabber, such as used in Qt Creator keyboard mapping. Can any body tell, if something already exist in free use. Or point me where to find, source of Qt Creator shortcut edit class grab ?

Create a class which inherits from QLineEdit.
And then , reimplement keyPressEvent()

This is a quick exemple !
@
GrabLineEdit::GrabLineEdit(QWidget *parent) :
QLineEdit(parent)
{
}

void GrabLineEdit::keyPressEvent(QKeyEvent *event)
{
QString grab;
switch ( event->modifiers())
{
case Qt::ShiftModifier : grab.append("Shift+");break;
case Qt::ControlModifier : grab.append("Ctrl+");break;
case Qt::AltModifier : grab.append("Alt+");break;
}

    grab.append(event->text());
    setText(grab);

// QLineEdit::keyPressEvent(event);

}

But some thing strange comes, when Ctrl pressed no key text
returned by QKeyEvent::text()

[A Former User]

solve problem with Ctrl and modify keyPressEvent function
@
void keyPressEvent(QKeyEvent *event)
{
QString grab;
int modifiers = event->modifiers();
if(modifiers & Qt::ControlModifier)
grab.append("Ctrl+");
if(modifiers & Qt::ShiftModifier)
grab.append("Shift+");
if(modifiers & Qt::AltModifier)
grab.append("Alt+");
grab.append(event->key());
setText(grab);
// QLineEdit::keyPressEvent(event);
}

Sorry for digging it out :)

Is there any way to solve this issue without inheriting QLineEdit?

P.S. I already built my ui so reimplementing a new class will be hard to me.

eventFilter comes to mind if you don't want to subclass
