attaching event with "ParameterTypeCategory"

mansoorbahrian

Hello Everyone,


I am developing an operator for RapidMiner.

My question is how to attach an event the dropdownbox  (i.e. ParameterTypeCategory), because I want to enable or disable few textfields on basis of selection.

Hi,
you might attach Conditions on parameters, which will hide them if the condition is not met. For example this code:

		
type = new ParameterTypeCategory(PARAMETER_IO_OBJECT, "The class of the object(s) which should be checked for existance.", objectArray, 0);
type.registerDependencyCondition(new EqualStringCondition(this, PARAMETER_CONDITION_TYPE, true, CONDITION_INPUT_EXISTS));
type.setExpert(false);
types.add(type);

It will create a parameter which will only be shown if the parameter CONDITION_TYPE is equal to CONDITION_INPUT_EXISTS.
