Lua / Lightroom SDK: how to access field text value?
I'm looking at plugins for Adobe Lightroom using their SDK, which is Lua. I'm just trying to understand one of their hello world examples. local LrFunctionContext = import 'LrFunctionContext' local LrBinding = import 'LrBinding' local LrDialogs = import 'LrDialogs' local LrView = import 'LrView' local LrColor = import 'LrColor' local LrLogger = import 'LrLogger' local myLogger = LrLogger( 'libraryLogger' ) MyHWLibraryItem = {} myLogger:enable( "print" ) -- or "logfile" function MyHWLibraryItem.outputToLog( message ) myLogger:trace( message ) end function MyHWLibraryItem.showCustomDialog() -- body of show-dialog function LrFunctionContext.callWithContext( "showCustomDialog", function( context ) -- body of called function local props = LrBinding.makePropertyTable( context ) -- create bound table props.isChecked = true -- add a property key and initial value -- create view hierarchy local f = LrView.osFactory() -- Create the contents for the dialog. local c = f:row { bind_to_object = props, -- Add a checkbox and an edit_field. f:checkbox { title = "Enable", value = LrView.bind( "isChecked" ), }, f:edit_field { value = "Some Text", enabled = LrView.bind( "isChecked" ) } } local result = LrDialogs.presentModalDialog( { title = "Custom Dialog", contents = c, -- the view hierarchy we defined } ) --this is where I am trying get the value of the text box MyHWLibraryItem.outputToLog(c.row.checkbox.title) end) end MyHWLibraryItem.showCustomDialog()So, what I want to do is send the value of the edit_field dialog box to the console (i.e. in Mac OSX).Questions:1) how to access the text in the dialog box?2) What is going on with the f:checkbox and f:edit_field where there are no () brackets and instead there are {} brackets? Why aren't those functions written like f:edit_field()?
