Depend
Qubes 6.7 Declares an explicit dependency.
Syntax
Depend(expression[, dependency1[, ...]])
expression = the expression whose value you want to retrieve
dependencyN = the expression's nth dependency
Remarks
This function allows you to declare explicit dependencies for an expression, relative to other expressions with which it has no implicit dependencies.
This can be used for instance to update a local time display, whenever a component changes (like an auto-incrementing button).
Examples
Depend(LocalNow, B1) = current date/time, updated each time B1 is recalculated
