UITextInput.HitTestCharacterIndex(IRenderer, float, string) Method
Definition
Namespace: Brine2D.UI
Returns the character index closest to screenX given the current scroll offset. Used to position the cursor on mouse click or drag. displayText should be Brine2D.UI.UITextInput.GetDisplayText so that password-masked fields are measured correctly. Widths are accumulated incrementally \(O\(n\) measurements instead of O\(n²\)).
