Detailed Description

An input control for real numbers, consisting of a spinbox and a slider.

since 5.0, use QSpinBox instead

KDoubleNumInput combines a QSpinBox and optionally a QSlider with a label to make an easy to use control for setting some float parameter. This is especially nice for configuration dialogs, which can have many such combinated controls.

The slider is created only when the user specifies a range for the control using the setRange function with the slider parameter set to "true".

A special feature of KDoubleNumInput, designed specifically for the situation when there are several instances in a column, is that you can specify what portion of the control is taken by the QSpinBox (the remaining portion is used by the slider). This makes it very simple to have all the sliders in a column be the same size.

Constructor & Destructor Documentation

◆ KDoubleNumInput() [1/3]

KDoubleNumInput::KDoubleNumInput ( QWidget parent = nullptr)

Constructs an input control for double values with initial value 0.00.

Definition at line 701 of file knuminput.cpp.

double  singleStep = 0.01,
int  precision = 2

Definition at line 709 of file knuminput.cpp.

◆ ~KDoubleNumInput()

Definition at line 728 of file knuminput.cpp.

◆ KDoubleNumInput() [3/3]

KDoubleNumInput::KDoubleNumInput ( KNumInput below,
double  lower,
double  upper,
double  value,
QWidget parent = nullptr,
double  singleStep = 0.02,
int  precision = 2 


the difference here is the "below" parameter. It tells this instance that it is visually put below some other KNumInput widget. Note that these two KNumInput's need not to have the same parent widget or be in the same layout group. The effect is that it'll adjust its layout in correspondence with the layout of the other KNumInput's (you can build an arbitrary long chain).

Member Function Documentation

◆ decimals()

int KDoubleNumInput::decimals ( ) const
number of decimals.
See also

◆ doLayout()

void KDoubleNumInput::doLayout ( )

You need to overwrite this method and implement your layout calculations there.

See KIntNumInput::doLayout and KDoubleNumInput::doLayout implementation for details.

Implements KNumInput.

Definition at line 882 of file knuminput.cpp.

◆ exponentRatio()

double KDoubleNumInput::exponentRatio ( ) const
the value of the exponent use to map the slider to the spin box.

◆ maximum()

double KDoubleNumInput::maximum ( ) const
the maximum value.

◆ minimum()

double KDoubleNumInput::minimum ( ) const
the minimum value.

◆ prefix()

QString KDoubleNumInput::prefix ( ) const
the prefix.
See also

◆ referencePoint()

double KDoubleNumInput::referencePoint ( ) const
the reference point for relativeValue calculation

◆ relativeValue()

double KDoubleNumInput::relativeValue ( ) const
the current value in units of referencePoint.

◆ relativeValueChanged

void KDoubleNumInput::relativeValueChanged ( double  )

This is an overloaded member function, provided for convenience.

It essentially behaves like the above function.

Contains the value in units of referencePoint.

◆ setDecimals()

void KDoubleNumInput::setDecimals ( int  decimals)

Specifies the number of digits to use.

Definition at line 1045 of file knuminput.cpp.

◆ setExponentRatio()

void KDoubleNumInput::setExponentRatio ( double  dbl)
dblthe value of the exponent use to map the slider to the spin box (dbl need to be strictly positive).

Definition at line 1081 of file knuminput.cpp.

◆ setLabel()

void KDoubleNumInput::setLabel ( const QString label,
Qt::Alignment  a = Qt::AlignLeft | Qt::AlignTop 

Sets the text and alignment of the main description label.

labelThe text of the label. Use QString() to remove an existing one.
aThe alignment of the label (Qt::Alignment). Default is Qt:AlignLeft | Qt:AlignTop.

The vertical alignment flags have special meaning with this widget:

@li @p Qt:AlignTop     The label is placed above the edit/slider
@li @p Qt:AlignVCenter The label is placed left beside the edit
@li @p Qt:AlignBottom  The label is placed below the edit/slider

Reimplemented from KNumInput.

Definition at line 1065 of file knuminput.cpp.

◆ setMaximum()

void KDoubleNumInput::setMaximum ( double  max)

Sets the maximum value.

Definition at line 982 of file knuminput.cpp.

◆ setMinimum()

void KDoubleNumInput::setMinimum ( double  min)

Sets the minimum value.

Definition at line 971 of file knuminput.cpp.

◆ setPrefix

void KDoubleNumInput::setPrefix ( const QString prefix)

Sets the prefix to be displayed to prefix.

Use QString() to disable this feature. Note that the prefix is attached to the value without any spacing.

Definition at line 1038 of file knuminput.cpp.

◆ setRange()

void KDoubleNumInput::setRange ( double  min,
double  max,
double  singleStep = 1,
bool  slider = true 
minminimum value
maxmaximum value
singleStepstep size for the QSlider
sliderwhether the slider is created or not

Definition at line 912 of file knuminput.cpp.

◆ setReferencePoint

void KDoubleNumInput::setReferencePoint ( double  ref)

Sets the reference Point to ref.

It ref == 0, emitting of relativeValueChanged is blocked and relativeValue just returns 0.

Definition at line 905 of file knuminput.cpp.

◆ setRelativeValue

void KDoubleNumInput::setRelativeValue ( double  r)

Sets the value in units of referencePoint.

Definition at line 895 of file knuminput.cpp.

◆ setSingleStep()

void KDoubleNumInput::setSingleStep ( double  singleStep)
the step of the spin box

Definition at line 998 of file knuminput.cpp.

◆ setSliderEnabled()

void KDoubleNumInput::setSliderEnabled ( bool  enabled)
enabledShow the slider @default enabled

Definition at line 934 of file knuminput.cpp.

◆ setSpecialValueText()

void KDoubleNumInput::setSpecialValueText ( const QString text)

Sets the special value text.

If set, the spin box will display this text instead of the numeric value whenever the current value is equal to minVal(). Typically this is used for indicating that the choice has a special (default) meaning.

Definition at line 1057 of file knuminput.cpp.

◆ setSuffix

void KDoubleNumInput::setSuffix ( const QString suffix)

Sets the suffix to be displayed to suffix.

Use QString() to disable this feature. Note that the suffix is attached to the value without any spacing. So if you prefer to display a space separator, set suffix to something like " cm".

Definition at line 1031 of file knuminput.cpp.

◆ setValue

void KDoubleNumInput::setValue ( double  val)

Sets the value of the control.

Definition at line 890 of file knuminput.cpp.

double KDoubleNumInput::singleStep ( ) const
the step of the spin box

◆ specialValueText()

QString KDoubleNumInput::specialValueText ( ) const
the string displayed for a special value.
