Detailed Description

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

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::KDoubleNumInput ( QWidget *  parent = 0)
explicit

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

Definition at line 697 of file knuminput.cpp.

KDoubleNumInput::KDoubleNumInput ( double  lower,
double  upper,
double  value,
QWidget *  parent = 0,
double  singleStep = 0.01,
int  precision = 2 
)

Constructor.

Parameters
lowerlower boundary value
upperupper boundary value
valueinitial value for the control
singleStepstep size to use for up/down arrow clicks
precisionnumber of digits after the decimal point
parentparent QWidget

Definition at line 705 of file knuminput.cpp.

KDoubleNumInput::~KDoubleNumInput ( )
virtual

destructor

Definition at line 724 of file knuminput.cpp.

KDoubleNumInput::KDoubleNumInput ( KNumInput *  below,
double  lower,
double  upper,
double  value,
QWidget *  parent = 0,
double  singleStep = 0.02,
int  precision = 2 
)

Constructor.

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).

Parameters
belowappend KDoubleNumInput to the KDoubleNumInput chain
lowerlower boundary value
upperupper boundary value
valueinitial value for the control
singleStepstep size to use for up/down arrow clicks
precisionnumber of digits after the decimal point
parentparent QWidget
Deprecated:
use the version without below instead

Definition at line 714 of file knuminput.cpp.

Member Function Documentation

int KDoubleNumInput::decimals ( ) const
Returns
number of decimals.
See also
setDecimals()
void KDoubleNumInput::doLayout ( )
protectedvirtual

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 876 of file knuminput.cpp.

double KDoubleNumInput::exponentRatio ( ) const
Returns
the value of the exponent use to map the slider to the spin box.
double KDoubleNumInput::maximum ( ) const
Returns
the maximum value.
double KDoubleNumInput::minimum ( ) const
Returns
the minimum value.
QSize KDoubleNumInput::minimumSizeHint ( ) const
virtual

Definition at line 807 of file knuminput.cpp.

QString KDoubleNumInput::prefix ( ) const
Returns
the prefix.
See also
setPrefix()
double KDoubleNumInput::referencePoint ( ) const
Returns
the reference point for relativeValue calculation
double KDoubleNumInput::relativeValue ( ) const
Returns
the current value in units of referencePoint.
void KDoubleNumInput::relativeValueChanged ( double  )
signal

This is an overloaded member function, provided for convenience.

It essentially behaves like the above function.

Contains the value in units of referencePoint.

void KDoubleNumInput::resizeEvent ( QResizeEvent *  e)
protected

Definition at line 836 of file knuminput.cpp.

void KDoubleNumInput::setDecimals ( int  decimals)

Specifies the number of digits to use.

Definition at line 1040 of file knuminput.cpp.

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

Definition at line 1076 of file knuminput.cpp.

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

Sets the text and alignment of the main description label.

Parameters
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 1060 of file knuminput.cpp.

void KDoubleNumInput::setMaximum ( double  max)

Sets the maximum value.

Definition at line 977 of file knuminput.cpp.

void KDoubleNumInput::setMinimum ( double  min)

Sets the minimum value.

Definition at line 966 of file knuminput.cpp.

void KDoubleNumInput::setPrecision ( int  precision)
inline

Definition at line 595 of file knuminput.h.

void KDoubleNumInput::setPrefix ( const QString &  prefix)
slot

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.

See also
setPrefix()

Definition at line 1033 of file knuminput.cpp.

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

Definition at line 906 of file knuminput.cpp.

void KDoubleNumInput::setReferencePoint ( double  ref)
slot

Sets the reference Point to ref.

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

Definition at line 899 of file knuminput.cpp.

void KDoubleNumInput::setRelativeValue ( double  r)
slot

Sets the value in units of referencePoint.

Definition at line 889 of file knuminput.cpp.

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

Definition at line 993 of file knuminput.cpp.

void KDoubleNumInput::setSliderEnabled ( bool  enabled)
Parameters
enabledShow the slider enabled

Definition at line 928 of file knuminput.cpp.

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 1052 of file knuminput.cpp.

void KDoubleNumInput::setSuffix ( const QString &  suffix)
slot

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".

See also
setSuffix()

Definition at line 1026 of file knuminput.cpp.

void KDoubleNumInput::setValue ( double  val)
slot

Sets the value of the control.

Definition at line 884 of file knuminput.cpp.

double KDoubleNumInput::singleStep ( ) const
Returns
the step of the spin box
QString KDoubleNumInput::specialValueText ( ) const
Returns
the string displayed for a special value.
See also
setSpecialValueText()
QString KDoubleNumInput::suffix ( ) const
Returns
the suffix.
See also
setSuffix()
double KDoubleNumInput::value ( ) const
Returns
the current value.
void KDoubleNumInput::valueChanged ( double  )
signal

Emitted every time the value changes (by calling setValue() or by user interaction).
