@short A spin box for fractional numbers.
This class provides a spin box for fractional numbers.
\image html kdoublespinbox.png "KDE Fractional Number Spinbox"
See below for code examples on how to use this class.
\b Parameters \n
To make successful use of KDoubleSpinBox, you need to understand the
relationship between precision and available range.
@li precision: The number of digits after the decimal point.
@li maxValue/minValue: upper and lower bounds of the valid range
@li lineStep: the size of the step that is made when the user hits
the up or down buttons
Since we work with fixed-point numbers internally, the maximum
precision is a function of the valid range and vice versa. More
precisely, the following relationships hold:
\code
max( abs(minValue()), abs(maxValue() ) <= INT_MAX/10^precision
maxPrecision = floor( log10( INT_MAX/max(abs(minValue()),abs(maxValue())) ) )
\endcode
Since the value, bounds and lineStep are rounded to the current
precision, you may find that the order of setting these
parameters matters. As an example, the following are @em not equivalent (try
it!):
\code
// sets precision,
// then min/max value (rounded to precision and clipped to obtainable range if needed)
// then value and lineStep
KDoubleSpinBox * spin = new KDoubleSpinBox( 0, 9.999, 0.001, 4.321, 3, this );
// sets minValue to 0; maxValue to 10.00(!); value to 4.32(!) and only then
// increases the precision - too late, since e.g. value has already been rounded...
KDoubleSpinBox * spin = new KDoubleSpinBox( this );
spin->setMinValue( 0 );
spin->setMaxValue( 9.999 );
spin->setValue( 4.321 );
spin->setPrecision( 3 );
