[static] QRgb QColorDialog::getRgba(QRgb initial = 0xffffffff, bool *ok = nullptr, QWidget *parent = nullptr)

Pops up a modal color dialog to allow the user to choose a color and an alpha channel (transparency) value. The color+alpha is initially set to initial. The dialog is a child of parent.

If ok is non-null, *a ok is set to true if the user clicked OK, and to false if the user clicked Cancel.

If the user clicks Cancel, the initial value is returned.

Use QColorDialog::getColor() instead, passing the QColorDialog::ShowAlphaChannel option.
