Detailed Description

The Sonnet Highlighter class, used for drawing red lines in text fields when detecting spelling mistakes.

SpellcheckHighlighter is adapted for QML applications. In usual Kirigami/QQC2-desktop-style applications, this can be used directly by adding Kirigami.SpellCheck.enabled: true on a TextArea.

On other QML applications, you can add the SpellcheckHighlighter as a child of a TextArea.

Note: TextField is not supported, as it lacks QTextDocument API that Sonnet relies on.

TextArea {
    id: textArea
    Sonnet.SpellcheckHighlighter {
        id: spellcheckhighlighter
        document: textArea.textDocument
        cursorPosition: textArea.cursorPosition
        selectionStart: textArea.selectionStart
        selectionEnd: textArea.selectionEnd
        misspelledColor: Kirigami.Theme.negativeTextColor
        active: true
 
        onChangeCursorPosition: {
            textArea.cursorPosition = start;
            textArea.moveCursorSelection(end, TextEdit.SelectCharacters);
        }
    }
}

Additionally SpellcheckHighlighter provides some convenient methods to create a context menu with suggestions.
