QLabel not giving updated txt - c++

Question

I added a QLabel inside my widget and it is editable through UI, able to set new text also, but not able to retrieve the updated text using function text();
QLabel *m_ColorName = new QLabel("_________");
m_ColorName->setTextInteractionFlags(Qt::TextSelectableByMouse | Qt::TextEditable);
In UI i am able to edit to new text but by calling function
m_ColorName->text();
Its giving default txt _________

It seems that although the text is editable, the data is not updated in the text, that can be solved with a hack, we use findChild to find the QTextDocument that is created when the flags are activated and get the text of that element:
QTextDocument *td = m_ColorName->findChild<QTextDocument *>();
if(td){
QString text = td->toRawText(); // >= Qt 5.9
// td->toPlainText();
// td->toHtml();
}
Example:
#include <QApplication>
#include <QLabel>
#include <QTextDocument>
#include <QTimer>
#include <QVBoxLayout>
#include <QWidget>
#include <QDebug>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWidget widget;
QLabel label("_________");
label.setTextInteractionFlags(Qt::TextSelectableByMouse | Qt::TextEditable);
widget.setLayout(new QVBoxLayout);
widget.layout()->addWidget(&label);
QTimer timer;
QObject::connect(&timer, &QTimer::timeout, [&label](){
QTextDocument *td = label.findChild<QTextDocument*>();
if(td){
qDebug()<<td->toRawText();
//qDebug()<<td->toPlainText();
//qDebug()<<td->toHtml();
}
});
timer.start(100);
widget.show();
return a.exec();
}
Output:
[...]
"________"
"________"
"_______"
"____f___"
"____f___"
"____ff___"
"____fff___"
"____fff___"
"____ffff___"
"____fffff___"
"____fffff___"
