How to change element ID in QML?

Question

Qt

Actually standard IDs like text1, text2, text3 are not informative at all, and therefore useless. How to rename them - if I do it through the Designer - it writes "incorrect ID" and does not allow editing, if I edit in the code - it also swears and underlines in red.
Those. this code is correct:

Text {
            id: text1
            x: 163
            y: 8
            width: 70
            height: 65
            text: qsTr("Раз-два-три")
            font.pixelSize: 20
        }

But this one isn't:

Text {
            id: CustomText
            x: 163
            y: 8
            width: 70
            height: 65
            text: qsTr("Раз-два-три")
            font.pixelSize: 20
        }

Answer 1

Everything turned out to be simple. Turns out the first character can't be a capital letter (idiocy!)
