Class, Method Overview

ColorPickerDialog

• ColorPickerDialog(color=QColor(255, 255, 255), orientation='horizontal')
  • color argument's type can be QColor or str.
  • orientation argument decides the overall layout direction of the dialog. There are two values. 'horizontal', 'vertical'. See layout preview below.
• getColor() -> QColor - get the color.

If you only want to use this as a part of window(not as whole dialog), use ColorPickerWidget(color=QColor(255, 255, 255), orientation='horizontal'). See the example below.

ColorPickerWidget

• colorChanged(color: QColor) - signal. After color being changed, this will be emitted.
• getCurrentColor() -> QColor - get the current color.
• setCurrentColor(QColor|str) - set the current color.
