initial position of a QSlider

[Thoosle]

Franco,

Sorry I wasn't paying attention to which version you're using. setSliderPosition method is in QT 4.

This shouldn't work but have you tried setting the "value" after the QSlider has been instantiated? If for some strange reason the QSlider wasn't being initialized properly this could show??

Thoosle yes I'm using QT 4.
I followed your suggestion and now it works, but I don't understand why .
Is possible to have a smooth movement of the cursor?

Regards,
Franco

Franco,

If you're using Qt4 then you need to look at the Qt4 docs, not Qt3. The QSlider constructor you show in your code is incorrect for Qt4. This is probably why it doesn't instantiate properly and why it works setting value after instantiation. QSlider has two constructors in Qt4 as follows:


QSlider ( QWidget * parent = 0 )

QSlider ( Qt::Orientation orientation, QWidget * parent = 0 )

Thanks for the link.
I didn't see the reference to qt 3 .
