D2Editor:setExpression is a function that is part of the D2Editor Library.
This function sets the contents of a D2Editor, and is a synonym of setText.
Syntax
D2Editor:setExpression(text, [cursor], [selection])
Sets the content to text, or appends it to a certain position if cursor is set. If selection is -1, no text is selected (?).
Example
function on.create()
editor = D2Editor.newRichText()
editor:move(0,0)
editor:resize(200,100)
end
function on.charIn(char)
currentText = editor:getText()
editor:setExpression(currentText .. char) -- or setText(...)
--Add char to the editor
end
function on.enterKey()
on.charIn(string.char(10))
--Add a new line
end
A very simple text editor (its actually more complicated that it be, but it shows the basics).
