Getting Started

You design and build visual components in the canvas designer.

  • You can save a Canvas section as a custom component which can be used as a custom gadget, embedded in a cell of a grid or embedded in a cell of a formgrid section.
  • Custom components are saved into the lib:/components/component_library/component_name directory as JavaScript code so that they can be used in Desktop, Web and Mobile Apps.
  • When you save a canvas section as a custom component the JavaScript code is automatically generated.
  • The name of the component is taken from the Canvas section Component Details attributes.
  • This code should not be edited as it will be generated automatically every time changes are saved to a "Custom Component page".
  • Components can be referenced using the notation component:/component_lib.component_name.
  • It is best practice to make component libraries unique to your organization e.g. com_yourcompany. This will allow them to be used by other developers without causing any name clashes.
  • When generating Web and Mobile Apps, components are included in the index.html file so there is no need to deploy them specifically.

Embedding a Visual Component

Components can be used in custom section and custom gadget code. You simply call the constructor function in JavaScript like this:

mycomponent = yourcomponentlib_componentname();
