Detailed Description

The QtxPopupSelection class is used as back-end for getting value of each parameter found in the rule by the expression parser.

For example, it can be used for the analyzing of the currently selected objects and defining the values of the parameters used in the rules syntax expression. Rules, in their turn, define each action state - visibility, enabled and toggled state.
