"Group Signal" to be emmited

[DeanQt]

Suppose I have numerous spinbox widgets, say 10 input widgets. I then have 1 output widget.
How do I write the signal slot connect code to make the output widget change after ANY of the input widgets are finished editing?

So for example, for 1 specific signal, the code would be:
@ connect (ui ->doubleSpinBox, SIGNAL (editingFinished()),this, SLOT (mySlot()));@

Now I could do this for every input widget, like so:
@ connect (ui ->doubleSpinBox, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_2, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_3, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_4, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_5, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_6, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_7, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_8, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_9, SIGNAL (editingFinished()),this, SLOT (mySlot()));@
@ connect (ui ->doubleSpinBox_10, SIGNAL (editingFinished()),this, SLOT (mySlot()));@

This is really tedious work. Can I not "group" or "family" all the input widgets into one group and make it so that if any of them are editingFinished, the output widget will change?

I think there isn't such a feature in Qt Creator or even in the Qt library.

Maybe you could use "QObject::children":http://doc-snapshot.qt-project.org/qdoc/qobject.html#children and "QObject::objectName":http://doc-snapshot.qt-project.org/qdoc/qobject.html#objectName-prop to filter your widgets. For example:
@
for(QObject child : widget->children()) {
if(child->objectName() == / some regexp here: doubleSpinBox_N */) {
connect(child, SIGNAL(editingFinished()), this, SLOT(mySlot()));
}
}

For this situation you can use "QSignalMapper":http://qt-project.org/doc/qt-5/qsignalmapper.html#details
