IGH_VariableParameterComponent Interface |
Implement this interface in your component if you want to enable variable parameter UI.
Namespace: Grasshopper.Kernel
Assembly: Grasshopper (in Grasshopper.dll)
SyntaxThe IGH_VariableParameterComponent type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CanInsertParameter |
This function will get called before an attempt is made to insert a parameter.
Since this method is potentially called on Canvas redraws, it must be fast.
|
| CanRemoveParameter |
This function will get called before an attempt is made to remove a parameter.
Since this method is potentially called on Canvas redraws, it must be fast.
|
| CreateParameter |
This function will be called when a new parameter is about to be inserted.
You must provide a valid parameter or insertion will be skipped.
You do not, repeat not, need to insert the parameter yourself.
|
| DestroyParameter |
This function will be called when a parameter is about to be removed.
You do not need to do anything, but this would be a good time to remove any event handlers
that might be attached to the parameter in question.
|
| VariableParameterMaintenance |
This method will be called when a closely related set of variable parameter
operations completes. This would be a good time to ensure all Nicknames and parameter
properties are correct. This method will also be called upon IO operations such as
Open, Paste, Undo and Redo.
