Guys,
I’m really sorry if the a dumb question. I’ve search big and low but have not been able to find an answer.
I need the user to type in text to the textField and have the typed text appear somewhere in the same scene.
Thanks in advance, Jel [import]uid: 13916 topic_id: 20140 reply_id: 320140[/import]
using the example from here
http://developer.anscamobile.com/reference/index/nativenewtextfield
I modified the snippet like that:
local defaultField
local function fieldHandler( getObj )
return function( event )
print( "TextField Object is: " .. tostring( getObj().text ) )
redoTxt.text = getObj().text
if ( "began" == event.phase ) then
elseif ( "ended" == event.phase ) then
print( "Text entered = " .. tostring( getObj().text ) ) -- display the text entered
elseif ( "submitted" == event.phase ) then
native.setKeyboardFocus( nil )
end
end
end
-- Create our Text Fields
defaultField = native.newTextField( 10, 30, 180, 30,
fieldHandler( function() return defaultField end ) ) -- passes the text field object
redoTxt = display.newText( "wait...", 10, 150, native.systemFont, 20 ) -finefin [import]uid: 70635 topic_id: 20140 reply_id: 78688[/import]
Thanks so much for that Canupa. I have a lot to learn =) [import]uid: 13916 topic_id: 20140 reply_id: 78696[/import]
If you only want one field, that example is overly complicated.
local function handlerFunction(event)
if event.phase == "submitted" then
local enteredText = editField.text
native.setKeyboardFocus(nil)
end
end
local editField = native.newTextField( 10, 125, 300, 36, handlerFunction )
editField.text = "some pre-filled text" Basically the object has a .text property that you can either read to get the contents or set to pre-fill the form.

Hi Canupa,
If I wanted to add more fields to the above code how would I do it ?
I’ve tried
local defaultField, default2Field
etc but still nothing works. it always prints to the lowest display.newText
Sorry for all the newbie questions
Thanks Jel [import]uid: 13916 topic_id: 20140 reply_id: 78772[/import]
You need to add new x and y coordinates to your new fields or they will all be on top of one another:
local editFieldB = native.newTextField( 10, 225, 300, 36, handlerFunction )
local editFieldC = native.newTextField( 10, 325, 300, 36, handlerFunction )
The first var (10) is the left position
The second var (225 and 325) is the top position [import]uid: 19193 topic_id: 20140 reply_id: 78792[/import]
Hi ScottPhillips,
Thanks for the response. Yep that’s all done but the problem is that typed text from either textField only prints to the second line, or bottom line I only have two lines at the moment.

Would you mind posting some example code, should be easy to fix, but hard to envision w/o seeing the code you’re using. [import]uid: 19193 topic_id: 20140 reply_id: 78860[/import]
local defaultField, numberField – forward reference (needed for Lua closure)
– TextField Listener
local function fieldHandler( getObj )
– Use Lua closure in order to access the TextField object
return function( event )
print( "TextField Object is: " … tostring( getObj() ) )
redoTxt.text = getObj().text
if ( “began” == event.phase ) then
– This is the “keyboard has appeared” event
elseif ( “ended” == event.phase ) then
– This event is called when the user stops editing a field:
– for example, when they touch a different field or keyboard focus goes away
print( "Text entered = " … tostring( getObj().text ) ) – display the text entered
elseif ( “submitted” == event.phase ) then
– This event occurs when the user presses the “return” key
– (if available) on the onscreen keyboard
– Hide keyboard
native.setKeyboardFocus( nil )
end
end – “return function()”
end
– Create our Text Field
defaultField = native.newTextField( 10, 30, 180, 30,
fieldHandler( function() return defaultField end ) ) – passes the text field object
redoTxt = display.newText( “text1…”, 10, 140, native.systemFont, 20 )
numberField = native.newTextField( 10, 70, 180, 30,
fieldHandler( function() return numberField end ) )
redoTxt = display.newText( “text2…”, 10, 180, native.systemFont, 20 ) [import]uid: 13916 topic_id: 20140 reply_id: 78887[/import]
Hi ScottPhillips,
Above is the code I’m using. I’m not sure whats the correct way is to post code on the Corona forum at the moment.
