81 | \brief The DynamicParameter (previously \l MapParameter ) type represents a parameter for a Map element, |
82 | or other elements used in a Map (such as map items, etc.). |
83 | This type provides a mean to specify plugin-dependent optional dynamic parameters that allow a plugin to |
84 | extend the runtime API of the module. |
85 | |
86 | |
87 | DynamicParameters by default contain only the \l type property, and |
88 | are highly plugin-dependent. |
89 | For this reason, additional properties have to be defined inside a |
90 | DynamicParameter at declaration time, using the QML syntax "property var foo". |
91 | |
92 | What properties have to be put inside a particular DynamicParameter type for |
93 | a particular plugin can be found in the documentation of the plugin. |
94 | \note DynamicParameters are \b optional. |
95 | By not specifying any of them, the Map, or other container elements, will have the default behavior. |
