This function can be used to create the loon object handles from a vector of the widget path name and the object ids (in the order of the parent-child relationships).

l_create_handle(target)

Arguments

target	loon object specification (e.g. ".l0.plot")

Details

loon's plot handles are useful to query and modify plot states via the command line.

Examples

# plot handle
p <- l_plot(x=1:3, y=1:3)
p_new <- l_create_handle(unclass(p))
p_new['showScales']
#> [1] FALSE

# glyph handle
gl <- l_glyph_add_text(p, text=LETTERS[1:3])
gl_new <- l_create_handle(c(as.vector(p), as.vector(gl)))
gl_new['text']
#> [1] "A" "B" "C"

# layer handle
l <- l_layer_rectangle(p, x=c(1,3), y=c(1,3), color='yellow', index='end')
l_new <- l_create_handle(c(as.vector(p), as.vector(l)))
l_new['color']
#> [1] "#FFFFFFFF0000"

# navigator handle
g <- l_graph(linegraph(completegraph(LETTERS[1:3])))
nav <- l_navigator_add(g)
nav_new <- l_create_handle(c(as.vector(g), as.vector(nav)))
nav_new['from']
#> [1] "A:B"

# context handle
con <- l_context_add_context2d(nav)
con_new <- l_create_handle(c(as.vector(g), as.vector(nav), as.vector(con)))
con_new['separator']
#> [1] ":"
