Answer 1

if you can change text input item from TextEdit to TextInput can use validator and regular expressions

from doc :

The RegExpValidator type provides a validator, which counts as valid any string which matches a specified regular expression.

in another way can get the onTextChanged signal and remove whitespace : like this :

TextEdit {
    width: 240
    text: "123"
    font.pointSize: 20
    color: "blue"
    onTextChanged:text = text.replace(/s+/g,'')
}
