Creative tab icon using block?

[Criminox]

So I want to use my block as the creative tab icon for my modblocks however i seem to be a little stuck.

package com.crim.parallelworlds.tab;

import com.crim.parallelworlds.block.ModBlocks;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.init.Blocks;
import net.minecraft.item.Item;

public class BlocksTab extends CreativeTabs{

	public BlocksTab(int index, String label) {
		super(index, label);
	}

	public Item getItemFromBlock() {
		return ModBlocks.nightore;
	}


}

This is the code from the creative tab but im unsure what parameter goes in the brackets for the getItemFromBlock, I thought it was just block but that doesnt seem to be it, any help here

Item.getItemFromBlock(Block) will return the ItemBlock instance of the Block.
