It showed the splash screen, cleared it and then I saw a screen with 10 B&W buttons with green circular backgrounds. This seems to be working without me changing anything.
Are you not seeing this?
is it taking you to the feed page ?
you can see there is feed,lua files on the project numbered from 1 to 10, for me I want the buttons from 1 to 10 to open the feed pages from 1 to 10, and also I want to put a back button to take me back to the main screen
could you please help me with that ???
I thought you were saying it was not going to the scene with the 10 buttons.
Your buttons are not working because you’re trying to call functions that don’t exist. For instance:
local button2 = widget.newButton({ id = "wed\_scn", defaultFile = "wed\_btn.png", overFile = "wed\_btn.png", width = 90, height = 90, label = "", labelColor = { default = { 0.90, 0.60, 0.34 }, over = { 0.79, 0.48, 0.30 } }, labelYOffset = -210, font = myApp.font, fontSize = 18, emboss = false, onRelease = myApp.showScreen3 }) sceneGroup:insert(button2) button2.x = display.contentCenterX - 1 button2.y = display.contentCenterY - 245
You try to call myApp.showScreen3, but that function doesn’t exist anywhere. BTW: You don’t need the myApp. on the front of those function calls in this scene. It was something needed to make the tabBar work in main.lua. Just define them as:
local function showScreen3() ... end
above the scene:create() function in menu.lua.

What is the code in the function myApp.showScreen2()?
Rob
I’m using the corona sample business app, if you mean the code inside myapp, the code is
local M = {}
return M
this is the whole code

Oh I recognized where the code originated. But that doesn’t mean you’ve not changed it since downloading. In main.lua functions were defined to handle the button presses:
In fact that block of code is:
function myApp.showScreen2(event) myApp.tabBar:setSelected(2) local options = { feedName = "corona.rss", -- feedURL = "http://www.coronalabs.com/feed/atom/", feedURL = "http://www.ems1.com/ems-rss-feeds/news.xml", icons = "fixed", displayMode = "webpage", pageTitle = "Corona Labs" } composer.removeHidden() composer.gotoScene("feed", {time=250, effect="crossFade", params = options}) return true end
in the original. (Also, when posting code please click on the <> in forum formatting bar above where you type and paste your code into the window that pops up).
So back to my question, what is the content of the myApp.showScreen2() function?
function myApp.showScreen1() myApp.button4Press = showScreen2 composer.removeHidden() composer.gotoScene("menu", {time=250, effect="crossFade"}) return true end
this is what inside that function
I did not know if I wrote it well ??
Is this not working? The code looks like what I would expect it to be.
NO
it is not working, when I press the button, it is not taking me to the specified scene
I am using an icons on the buttons
Is anything happening?
Are there any messages in the terminal/console window that the simulator opens in the background?
Can you put some print statements in the various functions to make sure they are getting called correctly?
Rob
NO
nothing is happening and written on the console
Can you post some more code.
Rob

First in menu.lua in the hide function, you make a call to storyboard. You should a) not call goto scene from the hide() event. You get this event because this scene is being hidden. b) its a storyboard call, not a composer call. Simply remove the line.
Next, menu.lua is missing all the functions to handle the buttons. I don’t know if this is causing errors or not. There should be something in the console log.
You can put in some print statements and try to watch the code execute.
Rob
if you mean this code
storyboard.gotoScene ( "storyboard-list")
this I wrote it as a test only and I removed it now,
the console is showing nothing when I press on the buttons,
could you please help me for how to write the good code so when I press the button it takes me to the specified scene ??
PLEASE I NEED YOUR HELP
Are you on a Mac or a PC?
i’m using both on my projects
Where are you actively developing this? Because there is an OS-X bug that sometimes causes the terminal window to not print things. On the Mac try running “Corona Terminal” instead of “Corona Simulator” and see if messages show up?
Rob
it is the same it is showing nothing when I press a button
if I but an image on a button is that affecting the button ?
