ActionItem :: setProperty - Change action item property

The function provides a generic way for changing action item properties. The value of the action item property passed in sProperty will be changed to the value passed in sValue. The following properties can be modified:

• name - action name
• action - name of action to be executed
• label - short action name
• tooltip - tool tip text defined for the action
• text - long text defined for the action (html)
• image - active image path defined for the action

• The plain_text property contains derived information (from text) and cannot be changed directly. Some of the properties mentioned above might be updated directly via property function calls as label() or image().
• The function throws an exception, when the requested action could not be found or when the requested property does not exist.
