Detailed Description
An input widget for integer numbers, consisting of a spinbox and a slider.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 or when the user calls setSliderEnabled.
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.

Constructor & Destructor Documentation
KIntNumInput::KIntNumInput | ( | QWidget * | parent = 0 |
) | [explicit] |
Constructs an input control for integer values with base 10 and initial value 0.
Definition at line 315 of file knuminput.cpp.
KIntNumInput::KIntNumInput | ( | int | value, | |
QWidget * | parent = 0 , |
|||
int | base = 10 | |||
) | [explicit] |
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:
-
value initial value for the control base numeric base used for display parent parent QWidget
Definition at line 322 of file knuminput.cpp.
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 its layout in correspondence with the layout of the other KNumInput's (you can build an arbitrary long chain).
- Parameters:
-
below append KIntNumInput to the KNumInput chain value initial value for the control base numeric base used for display parent parent QWidget
- Deprecated:
- use the version without the below parameter instead.

Member Function Documentation
void KIntNumInput::doLayout | ( | ) | [protected, virtual] |
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 513 of file knuminput.cpp.
int KIntNumInput::maximum | ( | ) | const |
- Returns:
- the maximum value.
int KIntNumInput::minimum | ( | ) | const |
- Returns:
- the minimum value.
QSize KIntNumInput::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
Definition at line 485 of file knuminput.cpp.
QString KIntNumInput::prefix | ( | ) | const |
int KIntNumInput::referencePoint | ( | ) | const |
- Returns:
- the current reference point
double KIntNumInput::relativeValue | ( | ) | const |
- Returns:
- the curent value in units of the referencePoint.
void KIntNumInput::relativeValueChanged | ( | double | ) | [signal] |
Emitted whenever valueChanged is.
Contains the change relative to the referencePoint.
void KIntNumInput::resizeEvent | ( | QResizeEvent * | e | ) | [protected] |
void KIntNumInput::setEditFocus | ( | bool | mark = true |
) | [slot] |
sets focus to the edit widget and marks all text in if mark == true
Reimplemented from QWidget.
Definition at line 480 of file knuminput.cpp.
void KIntNumInput::setLabel | ( | const QString & | label, | |
Qt::Alignment | a = Qt::AlignLeft | Qt::AlignTop | |||
) | [virtual] |
Sets the text and alignment of the main description label.
- Parameters:
-
label The text of the label. Use QString() to remove an existing one. a The alignment of the label (Qt::Alignment). Default is Qt:AlignLeft
|Qt:AlignTop
.
Qt:AlignTop
The label is placed above the edit/sliderQt:AlignVCenter
The label is placed left beside the editQt:AlignBottom
The label is placed below the edit/slider
Reimplemented from KNumInput.

void KIntNumInput::setMaximum | ( | int | max | ) |
void KIntNumInput::setMinimum | ( | int | min | ) |
void KIntNumInput::setPrefix | ( | const QString & | prefix | ) | [slot] |
Sets the prefix to prefix
.
Use QString() to disable this feature. Formatting has to be provided (see above).

void KIntNumInput::setRange | ( | int | min, | |
int | max, | |||
int | step, | |||
bool | slider | |||
) |
- Deprecated:
- Use the other setRange function and setSliderEnabled instead
Definition at line 430 of file knuminput.cpp.
void KIntNumInput::setRange | ( | int | min, | |
int | max, | |||
int | step = 1 | |||
) |
Sets the allowed input range and the step size for the slider and the spin box.
- Parameters:
-
min minimum value max maximum value step step size
Definition at line 414 of file knuminput.cpp.
void KIntNumInput::setReferencePoint | ( | int | ref | ) | [slot] |
void KIntNumInput::setRelativeValue | ( | double | r | ) | [slot] |
void KIntNumInput::setSliderEnabled | ( | bool | enabled = true |
) |
void KIntNumInput::setSpecialValueText | ( | const QString & | text | ) |
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.
Definition at line 596 of file knuminput.cpp.
void KIntNumInput::setSuffix | ( | const QString & | suffix | ) | [slot] |
Sets the suffix to suffix
.
Use QString() 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).

QSpinBox * KIntNumInput::spinBox | ( | ) | const [protected] |
QString KIntNumInput::suffix | ( | ) | const |
int KIntNumInput::value | ( | ) | const |
- Returns:
- the current value.
void KIntNumInput::valueChanged | ( | int | ) | [signal] |
Emitted every time the value changes (by calling setValue() or by user interaction).
