reset the Palette of my QWidget

[sattu]

Hi everyone,

For setting an image as the background image of my QWidget I am using the following code-

this->setAutoFillBackground(true);
QPalette palette = this->palette();
palette.setBrush(this->backgroundRole(), QBrush(QImage("MyImage.jpg")));
this->setPalette(palette);

this->setAutoFillBackground(true);
QPalette palette = this->palette();
palette.setBrush(this->backgroundRole(), QBrush(QImage("MyImage.jpg")));
this->setPalette(palette);

To copy to clipboard, switch view to plain text mode 

Now I want to reset my Palette and make my QWidget appear completely Black. How do I do that?
I tried using

QPixMap and QPixMap::fill(Qt::Black)

and then setting this PixMap to my Palette, but it didn't work

If you haven't change the parent's palette, just take that, otherwise take the one from the QApplication instance

setPalette(parentWidget()->palette());
// or
setPalette(QApplication::palette());

setPalette(parentWidget()->palette());
// or
setPalette(QApplication::palette());

To copy to clipboard, switch view to plain text mode 

Cheers,

Sorry for replying late. For the moment what I did is I put a QFrame over the widget I wanted to appear black and made the background of the QFrame as black. So that solved the issue but yes, it's not a good way of doing it.
So I will definitely try what you have written here and will get back if I face any issues.
