When working with multiline controls ctrlTextWidth or getTextWidth will not return a proper value since the text will be treated as one long line.
Solution (Execute in Eden Editor): disableSerialization; private _display = findDisplay 313 createDisplay "RscDisplayEmpty"; private _edit = _display ctrlCreate ["RscEditMulti", -1]; _edit ctrlSetPosition [0,0,1,1]; _edit ctrlSetBackgroundColor [0,0,0,1]; _edit ctrlSetFont "EtelkaMonospacePro"; _edit ctrlSetFontHeight 0.03; _edit ctrlCommit 0; private _longestLineWidth = 0; private _exampleString = "abcdefghijklmnopqrstuvxyz0134567890"; private _text = ""; for "_lines" from 1 to 400 do // Loop through all lines and find the longest one { _lineText = _exampleString select [round random 35]; _longestLineWidth = _longestLineWidth max (_lineText getTextWidth ["EtelkaMonospacePro", 0.03]); _text = _text + _lineText + endl; }; _edit ctrlSetPositionW (_longestLineWidth + 2 * 0.008); // Width of longest line + left and right margin set in engine _edit ctrlCommit 0; _edit ctrlSetText _text;

It's important to set the width of the multiline text control before adding any text to it.
