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, *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。
