Output elements

Matte.text_output — Function

text_output(id)

Render the output from the server as raw text.

This is best used with a formatting tag (such as p() or heading h1() etc)

source

Matte.datatable_output — Function

datatable_output(id::AbstractString; rows_per_page::Integer

Render a table of data in your UI. The function id in your Server module should return a table that is a subtype of either AbstractDataFrame or Table (from Tables.jl).

source

Matte.plots_output — Function

plots_output(id)

Render a plot. Supports plots created by the Plots package.

Plots are slow to render, and so should not be directly hooked up to inputs that rapidly request updates to the server – like sliders. If you wish to use these input types, add a button to refresh the plot input and only return the plot when that is true (otherwise return nothing).

Side effects / manually pushing updates to the UI

Matte.update_output — Function

ui_update(id, value, session)

Manually update a UI variable/element id to value. Use inside server-side functions for other outputs when you want calculations to have side effects in the UI.

session is the optional session argument to server-side functions that provides stateful variables. See the guides on server-side state and side effects for more information.

source

update_output is a way to manually change the value of an output variable in the UI from within the function for a different output variable. This is not the typical Matte computation model, but can be useful for logic flows like:

Setting and unsetting loading animations for long-running computations
Creating 'onclick' listeners for buttons that then change multiple elements

update_output must be passed an argument called session, and that variable must be an argument to the function from within which it is called. See the guide on server-side state for more details.
