Detailed Description

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 KDoubleNumInputs 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.

It uses KFloatValidator validator class. KDoubleNumInput enforces the value to be in the given range.

Constructor

put it below other KNumInput

Parameters:
valueinitial value for the control
parentparent QWidget
nameinternal name for this widget

double  value ()

value

[const]

Returns: the current value.

QString  suffix ()

suffix

[const]

Returns: the suffix.

See also: setSuffix()

QString  prefix ()

prefix

[const]

Returns: the prefix.

See also: setPrefix()

const char * format ()

format

[const]

Returns: the format.

See also: setFormat()

QString  specialValueText ()

specialValueText

[const]

Returns: the string displayed for a special value.

See also: setSpecialValueText()

void  setRange (double lower, double upper, double step=1, bool slider=true)

setRange

Parameters:
lowerlower bound on range
upperupper bound on range
stepstep size for the QSlider

void  setFormat (const char* format)

setFormat

Sets the format string that should be used to display the double value. The format string follows the same rules as the printf() function or QString::sprintf(). You can use this if you want to set the number of digits to be displayed, etc.

void  setSpecialValueText (const QString& text)

setSpecialValueText

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.

void  setLabel (QString label, int a = AlignLeft | AlignTop)

setLabel

[virtual]

Reimplemented from KNumInput for internal purposes..

QSize  minimumSizeHint ()

minimumSizeHint

[const virtual]

Reimplemented from QWidget for internal purposes..

bool  eventFilter (QObject*, QEvent*)

eventFilter

[virtual]

void  setValue (double)

setValue

[slot]

Sets the value of the control.

void  setSuffix (const QString &suffix)

setSuffix

[slot]

Sets the suffix to be displayed to suffix. Use QString::null 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()

void  setPrefix (const QString &prefix)

setPrefix

[slot]

Sets the prefix to be displayed to prefix. Use QString::null to disable this feature. Note that the prefix is attached to the value without any spacing.

See also: setPrefix()

void  valueChanged (double)

valueChanged

[signal]

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

void  doLayout ()

doLayout

[protected virtual]
