Add icon to plugin

[Gonvaz]

I'm trying to add an icon to a plugin but I can't make it work and I see no errors on the Ruby Console. Can you help?
Thanks in advance!

require 'Sketchup'

filename=File.basename(FILE)

if not file_loaded?(filename)
UI.menu('Plugins').add_item('Container creator') { JGV_FVC3.container_creator() }
end

#Toolbar test
if !file_loaded?("Container.rb")
#Container creator toolbar
FV_project_tb = UI::Toolbar.new("FV JGV")
#Container creator command
cmd3 = UI::Command.new(("Container creator")) { JGV_FVC3.container_creator() }
cmd3.small_icon = "containersmall.png"
cmd3.large_icon = "containerbig.png"
cmd3.tooltip = "Inserts a container"
FV_project_tb.add_item(cmd3)
end
#End Toolbar test

file_loaded(filename)

module JGV_FVC3

def self.container_creator

I think you need some extra lines to actually show your toolbar:

require 'Sketchup'

filename=File.basename(__FILE__)

if not file_loaded?(filename)
	UI.menu('Plugins').add_item('Container creator') { JGV_FVC3.container_creator() }
end

#Toolbar test
if !file_loaded?("Container.rb")
	#Container creator toolbar
	FV_project_tb = UI;;Toolbar.new("FV JGV")
	#Container creator command
	cmd3 = UI;;Command.new(("Container creator")) { JGV_FVC3.container_creator() }
	cmd3.small_icon = "containersmall.png"
	cmd3.large_icon = "containerbig.png"
	cmd3.tooltip = "Inserts a container"
	FV_project_tb.add_item(cmd3)
	if FV_project_tb.get_last_state==TB_NEVER_SHOWN
		FV_project_tb.show
	elsif FV_project_tb.get_last_state==TB_VISIBLE
		FV_project_tb.restore
	end
end
#End Toolbar test

file_loaded(filename)
