| |
| \brief The DynamicParameter (previously \l MapParameter ) type represents a parameter for a Map element, |
| or other elements used in a Map (such as map items, etc.). |
| This type provides a mean to specify plugin-dependent optional dynamic parameters that allow a plugin to |
| extend the runtime API of the module. |
| |
| |
| DynamicParameters by default contain only the \l type property, and |
| are highly plugin-dependent. |
| For this reason, additional properties have to be defined inside a |
| DynamicParameter at declaration time, using the QML syntax "property var foo". |
| |
| What properties have to be put inside a particular DynamicParameter type for |
| a particular plugin can be found in the documentation of the plugin. |
| \note DynamicParameters are \b optional. |
| By not specifying any of them, the Map, or other container elements, will have the default behavior. |
