cljfx-flowless

Cljfx-flowless is an idiomatic wrapper of Flowless library — an efficient virtual flow implementation similar to list view.

Installation

See latest version of io.github.vlaaad/cljfx-flowless on Clojars.

Requirements

cljfx/flowless requires Java 11.

Usage

A minimal code to try it out:

(require '[cljfx.api :as fx]
         '[cljfx.flowless :as fx.flowless])

(fx/on-fx-thread
  (fx/create-component
    {:fx/type :stage 
     :showing true
     :scene {:fx/type :scene 
             :root {:fx/type fx.flowless/virtualized-scroll-pane ;; add scroll bars
                    :content {:fx/type fx.flowless/virtual-flow
                              :cell-factory identity
                              :items (for [i (range 1000)]
                                       {:fx/type :label :text (str i)})}}}}))
