The BEEP component sends some "stupid beep" to the speaker of the client. The "beep" is triggered by a corresponding Trigger-property on server side.
There is an other component SOUND - which is the one to be used for playing sound files. The BEEP component uses the output of the ASCII beep character, which is also available on e.g. industry terminals without sound processor, or uses the default toolkit's beep processing.

Configuration information that is attached to this component. This information is not functionally used by CaptainCasa, but may be used for any application specific purpose.
Reference to an outside object that is the content behind the component. E.g. a field is representing a certain field of a database table: in this case you could define the value table;column. The reference plays a siginficant role within the attributemacro management.
The attribute value must not be changed once the component is created.
| ref | One reference |
| ref1;ref2 | Two references |
| ref1;ref2;ref3 | Three references |
Flag that indicated if this component is rendered at all. If set to false then the component is not rendered - there is no component data sent to the client.
The attribute value must be an expression.
| true | Component is rendered (default) |
| false | Component is not rendered |
In CaptainCasa you can define styles definitions for components. A style definition is a definition of a set of default attribute values that are applied to the component. In case you want to differenciate between different usage types of the component you can apply multiple styles - and use the stylevariant attribute to select between.
Trigger value: if the value changes then the component's activity is executed on client side. Use class Trigger on server side for implementations of this property.
The attribute value must be an expression.
