SpinBox like a slider

[Alundra]

Ok, thanks for the tip, but one problem remains, when you edit the value you can write "10.0001" but that will be truncated because of decimals allowed.
Is it possible to counter that, to set the number of decimals based on the value ?
Is the virtual valueFromText function the best to have that correctly ?
Thanks for the help

valueFromText sounds like a good choice.

The real problem now is how to allow the lineEdit() of QDoubleSpinBox to write infinite decimals before the trick of setDecimals.
I tried some method but no one worked, sounds like not so easy that sounds.

The line edit is probably using a QDoubleValidator as its validator(), you might need a different one.

I use this one :

const QString DecimalPointString = ( LocalDecimalPoint != "." ) ? LocalDecimalPoint : "";
lineEdit()->setValidator( new QRegExpValidator( QRegExp( "-?[0-9]*[." + DecimalPointString + "]?[0-9]{,2}" ), this ) );

He works good to have only number, - and . but it doesn't remove the block of decimals.

Using :

lineEdit()->setValidator( new QRegExpValidator( QRegExp( "-?[0-9]*[." + DecimalPointString + "]?[0-9]{,}" ), this ) );

That works to not have limit on decimals when write on the LineEdit but I have a last prob.

// Set default decimals.
setDecimals( 15 );

// Set default min/max.
setMinimum( -DBL_MAX );
setMaximum( +DBL_MAX );

This code make the lineEdit really big on the width.I can't have it little.
Maybe a fix exist ?
