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.
- 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
mycomponent = yourcomponentlib_componentname();
Customizing a Visual Component at runtime
When a Visual Components is instantiated you can customize the internal attributes and intercept events using delegates.
Arguments (Optional): props -- A string of attribute key/values separated with a ; initFunction -- The init delegate for this component loadFunction -- The load delegate for this component readyFunction -- The ready delegate for this component
var cont = example_component_barrytest("field1.table=customers;field3.backcolor=red;") return cont;
So as you can see its quite easy to use components from your component libraries in custom sections and gadgets.
