[Qt-interest] Overwriting public slots and qobject_cast

[Álvaro Morais]

Hi.

I want to make a custom progressBar that changes color with 
percentage. For example 25% will give a highlight red, 50% Yellow, 
etc...

It will also automatically give the password entropy of a QString, so 
the setValue SLOT will become private, since there is no need to 
change it from outside.

I'm using the promote to custom widget on the QtDesigner.

My question is: What is the best way of overwriting the public slots?

is it safe to do this:

class PasswordQuality : public QProgressBar
{
...
private slots:
    virtual void setValue ( int value ) {
	qobject_cast<QProgressBar*>(this)->setValue(value);
	
	... //code to change the palette.
	}
};

Am I using qobjet_cast the right way?

Thanks in advance.
