GetText
The GetText function opens a dialog to request a multi-line text string. If you click [OK], the entered text is returned.

sText, bOK = GetText( s=nil, sPrompt=nil, sTitle=nil )
s is the initial text string and may contain new lines separated using \r\n pairs, If nil, a blank string is used.
sPrompt is the message above the text field. If nil, a default is used.
sTitle is the window title. If nil, a default is used.
If [OK] is clicked, the function returns the text and bOK=true.
If the dialog is canceled, "",false is returned.
All arguments are optional and assume default values beyond the last argument you specify. In order to use a default argument but follow it with a specified argument, use a nil in its place.
If the string uses multiple lines, the string should be formatting using the \r\n escape sequence (the so-called carriage return / line feed pair) to separate the lines.
The window shown above was created using the following code. The last argument, the window title, was omitted and left to the default:
sText, bOK = GetText( |
|
"It is a tale told by an idiot\r\n" .. |
-- text (concatenated by ..) |
"full of sound and fury\r\n" .. |
-- text (concatenated by ..) |
"signifying nothing...", |
-- text (end of string) |
"Enter some Shakespeare :" ) |
-- prompt |
