Detailed Description

KIntNumInput combines a QSpinBox and optionally a QSlider with a label to make an easy to use control for setting some integer 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 KIntNumInput, designed specifically for the situation when there are several KIntNumInputs 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 KIntValidator validator class. KIntNumInput enforces the value to be in the given range, and can display it in any base between 2 and 36.

 KIntNumInput (QWidget *parent=0, const char *name=0)

KIntNumInput

Constructs an input control for integer values with base 10 and initial value 0.

 KIntNumInput (int value, QWidget* parent=0, int base = 10, const char *name=0)

KIntNumInput

Constructor It constructs a QSpinBox that allows the input of integer numbers in the range of -INT_MAX to +INT_MAX. To set a descriptive label, use setLabel(). To enforce the value being in a range and optionally to attach a slider to it, use setRange().

Parameters:
valueinitial value for the control
basenumeric base used for display
parentparent QWidget
nameinternal name for this widget

 KIntNumInput (KNumInput* below, int value, QWidget* parent=0, int base = 10, const char *name=0)

KIntNumInput

Constructor

the difference to the one above 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 it's layout in correspondence with the layout of the other KNumInput's (you can build an arbitary long chain).

Parameters:
belowappend KIntNumInput to the KNumInput chain
valueinitial value for the control
basenumeric base used for display
parentparent QWidget
nameinternal name for this widget

 ~KIntNumInput ()

~KIntNumInput

[virtual]

Destructor

int  value ()

value

[const]

Returns: the current value.

QString  suffix ()

suffix

[const]

Returns: the suffix displayed behind the value.

See also: setSuffix()

QString  prefix ()

prefix

[const]

Returns: the prefix displayed in front of the value.

See also: setPrefix()

QString  specialValueText ()

specialValueText

[const]

Returns: the string displayed for a special value.

See also: setSpecialValueText()

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

setRange

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

void  setSpecialValueText (const QString& text)

setSpecialValueText

Sets the special value text. If set, the SpinBox 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]

This method returns the minimum size necessary to display the control. The minimum size is enough to show all the labels in the current font (font change may invalidate the return value).

Returns: the minimum size necessary to show the control

Reimplemented from QWidget.

void  setValue (int)

setValue

[slot]

Sets the value of the control.

void  setSuffix (const QString &suffix)

setSuffix

[slot]

Sets the suffix to suffix. Use QString::null to disable this feature. Formatting has to be provided (e.g. a space separator between the prepended value and the suffix's text has to be provided as the first character in the suffix).

See also: QSpinBox::setSuffix(), setPrefix()

void  setPrefix (const QString &prefix)

setPrefix

[slot]

Sets the prefix to prefix. Use QString::null to disable this feature. Formatting has to be provided (see above).

See also: QSpinBox::setPrefix(), setSuffix()

void  setEditFocus ( bool mark = true )

setEditFocus

[slot]

sets focus to the edit widget and marks all text in if mark == true

void  valueChanged (int)

valueChanged

[signal]

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

void  doLayout ()

doLayout
