SliderGrid

Makie.SliderGrid <: Block

A grid of horizontal Sliders, where each slider has one name label on the left, and a value label on the right.

Each NamedTuple you pass specifies one Slider. You always have to pass range and label, and optionally a format for the value label. Beyond that, you can set any keyword that Slider takes, such as startvalue.

The format keyword can be a String with Formatting.jl style, such as "{:.2f}Hz", or a function.

Constructors

SliderGrid(fig_or_scene, nts::NamedTuple...; kwargs...)

Examples

sg = SliderGrid(fig[1, 1],
    (label = "Amplitude", range = 0:0.1:10, startvalue = 5),
    (label = "Frequency", range = 0:0.5:50, format = "{:.1f}Hz", startvalue = 10),
    (label = "Phase", range = 0:0.01:2pi,
        format = x -> string(round(x/pi, digits = 2), "π"))
)

Working with slider values:

on(sg.sliders[1].value) do val
    # do something with `val`
end

Attributes

Makie.SliderGrid attributes:

  • value_column_width: The width of the value label column. If automatic, the width is determined by sampling a few values from the slider ranges and picking the largest label size found. Default: automatic

Layout attributes:

  • alignmode: The align mode of the block in its parent GridLayout. Default: Inside()

  • halign: The horizontal alignment of the block in its suggested bounding box. Default: :center

  • height: The height setting of the block. Default: Auto()

  • tellheight: Controls if the parent layout can adjust to this block's height Default: true

  • tellwidth: Controls if the parent layout can adjust to this block's width Default: true

  • valign: The vertical alignment of the block in its suggested bounding box. Default: :center

  • width: The width setting of the block. Default: Auto()

The column with the value labels is automatically set to a fixed width, so that the layout doesn't jitter when sliders are dragged and the value labels change their widths. This width is chosen by setting each slider to a few values and recording the maximum label width. Alternatively, you can set the width manually with attribute value_column_width.
