For each graphical property for which there is a reset"Property" method, there is also a "property"IsSet method to check if the property is explicitly set. The "property"IsSet method returns true for an object if the property was set before (manually or through a call to set"Property") and this has not yet been restored to the default (by using the manual reset command or with a call to reset"Property").
If the property was not explicitly set, the "propery"IsSet method returns false.
The following "property"IsSet methods are available:
A value of the type Object or an expression evaluating to a value of that type.
A Boolean: true if the property is set to a non-default value, false otherwise.
