TextArea {
    id: text
    readOnly: true
    width: parent.width - 30
    textFormat: Text.RichText
    renderType: Text.NativeRendering
    text: "hello\nhelloh\nellohxxxellohello"
    selectByMouse: true
    selectionColor: "#7887FF"
    selectedTextColor: "#FFF"
}

After:

text.cursorPosition = 20;
text.moveCursorSelection(23, TextEdit.SelectCharacters);

How to know which line the specified position is in the TextArea?

You can try to get the whole text from the start to the position of the cursor. Then split it into a list of lines and return the length of the list.

   function currentLine(){
        let list = text.text.substring(0, text.cursorPosition).split(/\n/gm)
        return list.length
   }
