How to restore QFrame to its initial/default state

Absurd

I am subclassing a QFrame and I have some data members of my own there.
Initially, I am customizing the QFrame with some parameters such as:

myFrame->setFrameShape(QFrame::Panel);
myFrame->setFrameShadow(QFrame::Raised);
myFrame->setLineWidth(4);
...
...

And later I want that QFrame to be customized differently, but I want to do that on a clean slate.

Is there a way to restore a QFrame back to its default state (shape/shadow/background color/line width/etc...)?
Something along the lines of

myFrame->setToDefualt(); // sets MyFrame back to its defaults as if it was just now created with the 'new' operator

of course I could do:

delete myFrame;
myFrame = new MyFrame();

but I'd rather avoid that.

Move the lines where you set your default behavior into an own function and call it later on again when you want to reset to default.

Absurd

@Christian-Ehrlicher those lines are in a class ("FormatterA") that customizes the QFrame, and I have another class ("FormatterB") that will customize it differently (and in the future there might be more "Formatters"), but I don't want FormatterB to assume knowledge on FormatterA, I want FormatterB to just do myFrame->setToDefault() to cancel everything that's been done by FormatterA.

I can write my own myFrame->setToDefault() and have the Formatters invoke it, but that's prone to misses since another formatter in the future might change an attribute that wasn't initialized in myFrame->setToDefault().
So I thought maybe there's something like that that's provided by the object that I was missing...

@Absurd
There is no "restore object to default/as it was before FormatterA" call.

Only FormatterA knows exactly what it did to your object. Either export a method from FormatterA which knows how to reset what it did, or, just possibly, have it save all the original settings somehow in a subclassed QFrame and use those values to restore.
