Detailed Description

The QAbstractSpinBox class provides a spinbox and a line edit to display values.

The class is designed as a common super class for widgets like QSpinBox, QDoubleSpinBox and QDateTimeEdit

Here are the main properties of the class:

  1. text : The text that is displayed in the QAbstractSpinBox.

  2. alignment : The alignment of the text in the QAbstractSpinBox.

  3. wrapping : Whether the QAbstractSpinBox wraps from the minimum value to the maximum value and vica versa.

QAbstractSpinBox provides a virtual stepBy() function that is called whenever the user triggers a step. This function takes an integer value to signify how many steps were taken. E.g. Pressing Qt::Key_Down will trigger a call to stepBy(-1).

QAbstractSpinBox also provide a virtual function stepEnabled() to determine whether stepping up/down is allowed at any point. This function returns a bitset of StepEnabled.

◆ stepBy()

void QAbstractSpinBox::stepBy ( int  steps)
virtual

Virtual function that is called whenever the user triggers a step.

The steps parameter indicates how many steps were taken, e.g. Pressing Qt::Key_Down will trigger a call to stepBy(-1), whereas pressing Qt::Key_Prior will trigger a call to stepBy(10).

If you subclass QAbstractSpinBox you must reimplement this function. Note that this function is called even if the resulting value will be outside the bounds of minimum and maximum. It's this function's job to handle these situations.

Reimplemented in QDateTimeEdit.

Properties

◆ accelerated

QAbstractSpinBox::accelerated
private

whether the spin box will accelerate the frequency of the steps when pressing the step Up/Down buttons.

Since
4.2

If enabled the spin box will increase/decrease the value faster the longer you hold the button down.

Definition at line 74 of file qabstractspinbox.h.

◆ acceptableInput

QAbstractSpinBox::acceptableInput
private

whether the input satisfies the current validation

Since
4.2
See also
validate(), fixup(), correctionMode

Definition at line 76 of file qabstractspinbox.h.

◆ alignment

Qt::Alignment QAbstractSpinBox::alignment
private

the alignment of the spin box

Possible Values are Qt::AlignLeft, Qt::AlignRight, and Qt::AlignHCenter.

By default, the alignment is Qt::AlignLeft

Attempting to set the alignment to an illegal flag combination does nothing.

See also
Qt::Alignment

Definition at line 69 of file qabstractspinbox.h.

◆ buttonSymbols

QAbstractSpinBox::ButtonSymbols QAbstractSpinBox::buttonSymbols
private

the current button symbol mode

The possible values can be either UpDownArrows or PlusMinus. The default is UpDownArrows.

Note that some styles might render PlusMinus and UpDownArrows identically.

See also
ButtonSymbols

Definition at line 71 of file qabstractspinbox.h.

◆ correctionMode

QAbstractSpinBox::CorrectionMode QAbstractSpinBox::correctionMode
private

the mode to correct an QValidator::Intermediate value if editing finishes

Since
4.2

The default mode is QAbstractSpinBox::CorrectToPreviousValue.

See also
acceptableInput, validate(), fixup()

Definition at line 75 of file qabstractspinbox.h.

◆ frame

QAbstractSpinBox::frame
private

whether the spin box draws itself with a frame

If enabled (the default) the spin box draws itself inside a frame, otherwise the spin box draws itself without any frame.

Definition at line 68 of file qabstractspinbox.h.

◆ keyboardTracking

bool QAbstractSpinBox::keyboardTracking
private

whether keyboard tracking is enabled for the spinbox.

Since
4.3

If keyboard tracking is enabled (the default), the spinbox emits the valueChanged() signal while the new value is being entered from the keyboard.

E.g. when the user enters the value 600 by typing 6, 0, and 0, the spinbox emits 3 signals with the values 6, 60, and 600 respectively.

If keyboard tracking is disabled, the spinbox doesn't emit the valueChanged() signal while typing. It emits the signal later, when the return key is pressed, when keyboard focus is lost, or when other spinbox functionality is used, e.g. pressing an arrow key.

Definition at line 77 of file qabstractspinbox.h.

◆ readOnly

QAbstractSpinBox::readOnly
private

whether the spin box is read only.

In read-only mode, the user can still copy the text to the clipboard, or drag and drop the text; but cannot edit it.

The QLineEdit in the QAbstractSpinBox does not show a cursor in read-only mode.

See also
QLineEdit::readOnly

Definition at line 70 of file qabstractspinbox.h.

◆ specialValueText

QString QAbstractSpinBox::specialValueText
private

the special-value text

If set, the spin box will display this text instead of a numeric value whenever the current value is equal to minimum(). Typical use is to indicate that this choice has a special (default) meaning.

For example, if your spin box allows the user to choose a scale factor (or zoom level) for displaying an image, and your application is able to automatically choose one that will enable the image to fit completely within the display window, you can set up the spin box like this:

QSpinBox *zoomSpinBox = new QSpinBox;
zoomSpinBox->setRange(0, 1000);
zoomSpinBox->setSingleStep(10);
zoomSpinBox->setSuffix("%");
zoomSpinBox->setSpecialValueText(tr("Automatic"));
zoomSpinBox->setValue(100);

The user will then be able to choose a scale from 1% to 1000% or select "Auto" to leave it up to the application to choose. Your code must then interpret the spin box value of 0 as a request from the user to scale the image to fit inside the window.

All values are displayed with the prefix and suffix (if set), except for the special value, which only shows the special value text. This special text is passed in the QSpinBox::valueChanged() signal that passes a QString.

To turn off the special-value text display, call this function with an empty string. The default is no special-value text, i.e. the numeric value is shown as usual.

If no special-value text is set, specialValueText() returns an empty string.

Definition at line 72 of file qabstractspinbox.h.

◆ text

QString QAbstractSpinBox::text
private

the spin box's text, including any prefix and suffix

There is no default text.

Definition at line 73 of file qabstractspinbox.h.

Referenced by QAccessibleAbstractSpinBox::text().

◆ wrapping

bool QAbstractSpinBox::wrapping
private

whether the spin box is circular.

If wrapping is true stepping up from maximum() value will take you to the minimum() value and vica versa. Wrapping only make sense if you have minimum() and maximum() values set.

QSpinBox *spinBox = new QSpinBox(this);
spinBox->setRange(0, 100);
spinBox->setWrapping(true);
spinBox->setValue(100);
spinBox->stepBy(1);
// value is 0
