System.Type memberTypeMustDerive

Fields

MemberName

Which property we're watching, or 'determine from context' if null.

public readonly string MemberName
Field Value
Type Description
System.String

MemberTypeMustDerive

Only watch types that are derived from this specific class or interface.

OverridenType

This is used with TooltipAffectedByAttribute and specifically when watching an event on a method that has a NewTooltip attribute and an override type. This can be removed when we move the NewTooltip to Eco.Core, which then we can just make a function as an extansion of System.Reflection.MethodInfo which give us the real root type of that method (Detect whether that method has a NewTooltip attribute and return the Override property.

WatchAllSubMembers

If set, ignore the SubMemberName and watch all sub properties.

Declaration
public readonly bool WatchAllSubMembers
Field Value
