This class provides a spin box for fractional numbers.

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 );
|
|
\endcode
