Color Picker¶

New in version 1.7.0.

Warning

This widget is experimental. Its use and API can change at any time until this warning is removed.

The ColorPicker widget allows a user to select a color from a chromatic wheel where pinch and zoom can be used to change the wheel’s saturation. Sliders and TextInputs are also provided for entering the RGBA/HSV/HEX values directly.

Usage:

clr_picker = ColorPicker()
parent.add_widget(clr_picker)

# To monitor changes, we can bind to color property changes
def on_color(instance, value):
    print "RGBA = ", str(value)  #  or instance.color
    print "HSV = ", str(instance.hsv)
    print "HEX = ", str(instance.hex_color)

clr_picker.bind(color=on_color)
