Icons

Icons are all item stacks shown on GUI.

Creating Icon

Icon icon = new Icon(new ItemStack(Material.STONE));
//or
Icon icon = new Icon(Material.STONE);

Editing Icon Item Stack

icon.setName("");

icon.setLore(stringArrayList);
//or
icon.setLore("1st line", "2nd line");

icon.appendLore("3th line");
icon.insertLore(0, "0th line");

icon.setAmount(64);

icon.hideFlags(ItemFlag.HIDE_ENCHANTS);
//or all flags
icon.hideFlags();

icon.enchant(Enchantment.ARROW_DAMAGE); //supports enchanted book enchantments
//or
icon.enchant(Enchantment.ARROW_DAMAGE, 2); 
//or
icon.enchant(enchantmentsMap);
		
icon.setDurability(10);

Listening Icon Actions

icon.onClick(event -> {
    player.sendMessage("you clicked to an icon.");
});

icon.onDrag(event -> {
    player.sendMessage("you dragged an icon.");
});

Registering Icons

Each line has same function. Puts a dysfunctional stone icon to 0. slot of GUI.

addItem(0, Material.STONE);
addItem(0, new ItemStack(Material.STONE));
addItem(0, new Icon(new ItemStack(Material.STONE)));
addItem(0, new Icon(Material.STONE));

Fill Methods

fillGui(new ItemStack(Material.BLACK_STAINED_GLASS_PANE));
fillGui(new Icon(Material.BLACK_STAINED_GLASS_PANE), 10,11,12); // fills all GUI except 10., 11. and 12. slots.
fillColumn(new Icon(Material.BLACK_STAINED_GLASS_PANE), 0); // column numbers are starting from 0.
fillRow(new Icon(Material.BLACK_STAINED_GLASS_PANE), 0); // row numbers are starting from 0.

Note

Icon methods returns the object again. This is means you can make that:

new Icon(Material.STONE).setName("Stone").setLore("it is a special stone").setAmount(10);
