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;
