InjectionArgs Object

Summary

Event data for the inject event.

Syntax
TypeScript
JavaScript
function lt.LEADVIEW.InjectionArgs 
class lt.LEADVIEW.InjectionArgs() 
Remarks

The InjectionManager fires the inject event when an injection site is created, as well as when it is about to be removed. The event allows users to inject their own custom UI components into LEADVIEW.

Example
InjectionManager.ts
InjectionManager.html
export class InjectionManagerExample { 
   public constructor() { 
      if (lt.RasterSupport.kernelExpired) 
         lt.RasterSupport.setLicenseUri("https://demo.leadtools.com/licenses/js/LEADTOOLSEVAL.txt", "EVAL", null); 
 
      lt.LEADVIEW.InjectionManager.Instance.inject = this.inject; 
   } 
 
   public run = (divID: string): void => { 
      const lv = new lt.LEADVIEW.Viewer(); 
 
      lv.run(null, { 
         'rootDivId': divID 
      }); 
   }

       * Simple example for showcasinbg injection functionality. 
       * We will inject a red square in every area that is capable of being injected. 
       * 
       * Since we are not wiring up any callbacks -- we don't need to perform any 
       * cleanup actions, so we can ignore all unmounting calls.
