How in Reagent with Hiccup make an element with takes all available space

I am trying to find out how in Reagent with Hiccup make an element with takes all available space. So an resize parent I will get :component-did-mount call back.

(defn chart [id col-width row-height]
  (let [dimensions (atom {})]
    (reagent/create-class
      {:component-did-mount
       (fn [e]
         (let [thisComponent (aget (js/document.querySelector ".app") "parentNode")
               width (aget thisComponent "offsetWidth")
               height (aget thisComponent "offsetHeight")]
           (swap! dimensions {:width width :height height})
           (println "----did mountwdth" width "--" height col-width row-height)
           (.log js/console thisComponent)))
       :reagent-render
       (fn [id col-width row-height]
         [:div
          [:div {:style {:background "gray"}} "--drag handle--"]
          [:div.non-dragable
           [simple-bar id]
           [tchart id col-width (int (- row-height controls-height))]]])})))

I want the chart element to take all the space available.

Solution

  • React lifecycle callbacks like ComponentDidMount does not react to component size changes.

    If you want to fire a callback whenever the component size changes - you'll need to use some third-party React libraries like react-measure or react-sizeme

    The other strategy is to add an event listener on window resize and get your component's parent size from there.
