Hi all,

I just read the api regarding to the spinner method, after research and follow to what it said nothing appear on the simulator,

I am trying to create a spinner to display on my device, here is the code:

local widget = require( “widget” )

– Create a default spinner (using widget.setTheme)

local spinnerDefault = widget.newSpinner

{

    left = 150,

    top = 150,

    sheet = “refresh.png”,

    data = { width = 44, height = 44, numFrames = 1, sheetContentWidth = 44, sheetContentHeight = 44},

    width=44,

    height=44,

    startFrame = 1, frameCount = 1,

    time = 1000

}

spinnerDefault:start();

spinnerDefault:stop();

what’s wrong with this code

Hi Keat,

Where is the “data” setting coming from? Did you create an actual image sheet with your “refresh.png” image on it?

Hi Keat,

I haven’t tested this, but try creating the image sheet first, then referencing it in the Spinner:

[lua]

local mySheet = graphics.newImageSheet( “refresh.png”, width=44, height=41, numFrames=1, sheetContentWidth=44, sheetContentHeight=44  )

local spinnerDefault = widget.newSpinner

{

    left = 150,

    top = 150,

    sheet = mySheet,

    width=44,

    height=44,

    startFrame = 1, frameCount = 1,

    time = 1000

}

[/lua]

Hi Brent,

I tried to test this code many time but still got an error in corona simulator output said that:

main.lua"1: ‘)’ expected near ’ = ’

I tried to check the syntax of imagesheet and found nothing error.

Pls help me to test this code

Many thanks

Hi Keat,

My fault on that… the options/parameters for the image sheet must be contained in a table:

[lua]

local mySheet = graphics.newImageSheet( “refresh.png”, { width=44, height=41, numFrames=1, sheetContentWidth=44, sheetContentHeight=44 }  )

[/lua]

Hi Brent,

Just the curly bracket and make the code ok.

I really love for the community and the fast respond to my question,

You deserved the best.

Still say thank you again,
