[static] QRgb QColorDialog:: getRgba ( QRgb initial = 0xffffffff, bool * ok = Q_NULLPTR, QWidget * parent = Q_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 .

若 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.

使用 QColorDialog::getColor () instead, passing the QColorDialog::ShowAlphaChannel 选项。
