# JScript Example: No UI for Parameter Definition

This example produces the following UI:

    function XSILoadPlugin( in_reg )
    {
    	in_reg.Author = "SDK Documentation";
    	in_reg.Name = "LayoutTests";
    	in_reg.Major = 1;
    	in_reg.Minor = 0;

    	in_reg.RegisterShader("NoLayoutEx", 1, 0);
    	return true;
    }
    function LayoutTests_NoLayoutEx_1_0_DefineInfo( in_ctxt )
    {
    	in_ctxt.SetAttribute("Category", "Test Shaders/Layout@700");
    	return true;
    }

    function LayoutTests_NoLayoutEx_1_0_Define( in_ctxt )
    {
    	var oShaderDef = in_ctxt.GetAttribute("Definition");
    	oShaderDef.AddShaderFamily(siShaderFamilyTexture);

    	// Add 2 input parameters as connectable ports
    	var oInputParamsContainer = oShaderDef.InputParamDefs;
    	var oPDefOptions = XSIFactory.CreateShaderParamDefOptions();
    	oPDefOptions.SetTexturable(true);
    	oPDefOptions.SetInspectable(false);
    	oInputParamsContainer.AddParamDef("port1", siShaderDataTypeColor4, oPDefOptions);
    	oInputParamsContainer.AddParamDef("port2", siShaderDataTypeInteger, oPDefOptions);

    	// Add 2 input parameters on property page
    	oPDefOptions.SetTexturable(false);
    	oPDefOptions.SetInspectable(true);
    	oInputParamsContainer.AddParamDef("param1", siShaderDataTypeString, oPDefOptions);
    	oInputParamsContainer.AddParamDef("param2", siShaderDataTypeBoolean, oPDefOptions);

    	// Add 1 input parameters that won't appear in UI
    	oPDefOptions.SetInspectable(false);
    	oInputParamsContainer.AddParamDef("uiless", siShaderDataTypeScalar, oPDefOptions);
    	// Add the output color
    	var oOutputParamsContainer = oShaderDef.OutputParamDefs;
    	oOutputParamsContainer.AddParamDef("out", siShaderDataTypeColor4, oPDefOptions);

    	// Add renderer info

    	return true;
    }
