public void override_cursor (RGBA? cursor, RGBA? secondary_cursor)
Warning: override_cursor is deprecated since 3.16.
Sets the cursor color to use in a widget, overriding the cursor-color and secondary-cursor-color style properties.
This function is not useful in the context of CSS-based rendering. If you wish to change the color used to render the primary and secondary cursors you should use a custom CSS style, through an application-specific StyleProvider and a CSS style class.
All other style values are left untouched. See also modify_style.
Note that the underlying properties have the Color type, so the alpha value in
secondary will be ignored.
