opts_hover: Hover effect settings

Description

Allows customization of the rendering of graphic elements when the user hovers over them with the cursor (mouse pointer). Use opts_hover for interactive geometries in panels, opts_hover_key for interactive scales/guides and opts_hover_theme for interactive theme elements. Use opts_hover_inv for the effect on the rest of the geometries, while one is hovered (inverted operation).

Usage

opts_hover(css = NULL, reactive = FALSE)
opts_hover_inv(css = NULL)
opts_hover_key(css = NULL, reactive = FALSE)
opts_hover_theme(css = NULL, reactive = FALSE)

Arguments

css

css to associate with elements when they are hovered. It must be a scalar character. It can also be constructed with girafe_css, to give more control over the css for different element types.

reactive

if TRUE, in Shiny context, hovering will set Shiny input values.
