Watch Gradient Spot

The watch gradientm spot widget allows you to create a pointer watchface with dynamic water drops in the center.

Usage

Create Widget

You can create a watch gradient spot widget by calling the gui_watch_gradient_spot_create().

Set Center

The center position of the widget can be freely set by using the gui_watch_gradient_spot_set_center() function to change the center position, where c_x and c_y are the coordinate points of the central position.
