StandardControl.init

  • Artikkeli

Used to initialize the component instance. Components can kick off remote server calls and other initialization actions. Dataset values cannot be initialized here, use the updateView method to achieve that.

trackContainerResize should be called once, preferably in the component init method to notify that the component needs the layout information. Use this method to tell the framework to populate allocatedHeight and allocatedWidth methods.

Note

tractContainerResize should be called first before the allocatedHeight and allocatedWidth methods.

Available for

Model-driven apps, canvas apps, & portals.
