SiSpinBox Class Reference

A spin box with SI prefix support. This spin box supports the SI prefixes (k/M/G/T) after its value and allows floating point values. The step size is increasing in an exponential way, to keep the percentual difference between the steps at equal levels. More...

Member Function Documentation

fixup()

void SiSpinBox::fixup

(

QString &

input

)

const

Fixes the text after the user finished changing it.

Parameters

input

The content of the text box.

setMode()

void SiSpinBox::setMode

(

const int

mode

)

Set the mode.

Parameters

mode	The mode, the value 0 will have fixed interval, otherwise the value will have interval within steps itself.

setSteps()

void SiSpinBox::setSteps

(

const QList< double > &

steps

)

Set the steps the spin box will take.

Parameters

steps

The steps, will be extended with the ratio from the start after the last element.

setUnit()

bool SiSpinBox::setUnit

(

Unit

unit

)

Set the unit for this spin box.

Parameters

unit	The unit shown for the value in the spin box.

Returns

true on success, false on invalid unit.

setUnitPostfix()

void SiSpinBox::setUnitPostfix

(

const QString &

postfix

)

Parameters

postfix

the string shown after the unit in the spin box.

stepBy()

void SiSpinBox::stepBy

(

int

steps

)

Increase/decrease the values in fixed steps.

Parameters

steps

The number of steps, positive means increase.

textFromValue()

QString SiSpinBox::textFromValue

(

double

val

)

const

Get string representation of value.

Parameters

val	Value in base unit.

Returns

String representation containing value and (prefix+)unit.

validate()
