                    font.pixelSize: 22
                    width: 350
                    placeholderText: "Write your tweet"
                    platformSipAttributes: sipAttributes
                    maximumLength: 30

                    Keys.onReturnPressed: twitText.closeSoftwareInputPanel();
}

Attached are the screenshot for with and without the SipAttributes. Hope it helps
