Disabling the user to change QCheckBox checkstate

[ChiliPalmer]

Hi

I'm trying to show a bool value with a QCheckBox, that the user shouldn't be able to change, but without changing the appearance of the QCheckBox.

This is what I've got so far:

checkBox->setEnabled(false);
QPalette palette(checkBox->palette());
palette.setColor(QPalette::Disabled, QPalette::WindowText, QColor(Qt::black));
checkBox->setPalette(palette);

checkBox->setEnabled(false);
QPalette palette(checkBox->palette());
palette.setColor(QPalette::Disabled, QPalette::WindowText, QColor(Qt::black));
checkBox->setPalette(palette);

To copy to clipboard, switch view to plain text mode 

That changes the text color back to black, but the checked indicator still is grey.
I tried to change it with a style-sheet:

checkBox->setStyleSheet("::indicator { border-color: black; }");

checkBox->setStyleSheet("::indicator { border-color: black; }");

To copy to clipboard, switch view to plain text mode 

...with that the indicator isn't visible.

checkBox->setStyleSheet("::indicator { width: 12px; height: 12px; border-width: 1px; border-style: solid; border-color: black; }");

checkBox->setStyleSheet("::indicator { width: 12px; height: 12px; border-width: 1px; border-style: solid; border-color: black; }");

To copy to clipboard, switch view to plain text mode 

... with that it is, but it just looks weird, plus the check doesn't show.

There has to be a simpler way.
I already thought about just connecting the QCheckBox toggled(bool checked) signal to a slot connected to:

void::myClass checkBoxToggled(bool checked)
{
     checkbox->setChecked(whatever I need);
}

void::myClass checkBoxToggled(bool checked)
{
     checkbox->setChecked(whatever I need);
}

To copy to clipboard, switch view to plain text mode 

..or something like that.

Any suggestions?
