I wanted to know how to create an image a button and when clicked it changes scenes for my app.

And Also I wanted to know how to make a tab menu like facebook. And i am a noob at promgramming.

First look how to create a simple image,

local image = display.newImageRect(“image.png”, 50,50)

image.x = display.contentWidth/2

image.y = display.contentHeight/2

Creating a button 

local widget = require( “widget” )

– Function to handle button events
local function handleButtonEvent( event )

if ( “ended” == event.phase ) then

composer.gotoScene(“menu”)
print( “Button was pressed and released” )
end
end

– Create the widget
local button1 = widget.newButton
{
left = 100,
top = 200,
id = “button1”,
label = “Default”,
onEvent = handleButtonEvent
}
