Struct qt_widgets::QDoubleSpinBox

#[repr(C)]
pub struct QDoubleSpinBox { /* fields omitted */ }

The QDoubleSpinBox class provides a spin box widget that takes doubles.

C++ class: QDoubleSpinBox.

C++ documentation:

The QDoubleSpinBox class provides a spin box widget that takes doubles.

QDoubleSpinBox allows the user to choose a value by clicking the up and down buttons or by pressing Up or Down on the keyboard to increase or decrease the value currently displayed. The user can also type the value in manually. The spin box supports double values but can be extended to use different strings with validate(), textFromValue() and valueFromText().

Every time the value changes QDoubleSpinBox emits two valueChanged() signals, one taking providing a double and the other a QString. The QString overload provides the value with both prefix() and suffix(). The current value can be fetched with value() and set with setValue().

Note: QDoubleSpinBox will round numbers so they can be displayed with the current precision. In a QDoubleSpinBox with decimals set to 2, calling setValue(2.555) will cause value() to return 2.56.

Clicking the up and down buttons or using the keyboard accelerator's Up and Down arrows will increase or decrease the current value in steps of size singleStep(). If you want to change this behavior you can reimplement the virtual function stepBy(). The minimum and maximum value and the step size can be set using one of the constructors, and can be changed later with setMinimum(), setMaximum() and setSingleStep(). The spinbox has a default precision of 2 decimal places but this can be changed using setDecimals().

Most spin boxes are directional, but QDoubleSpinBox can also operate as a circular spin box, i.e. if the range is 0.0-99.9 and the current value is 99.9, clicking "up" will give 0 if wrapping() is set to true. Use setWrapping() if you want circular behavior.

The displayed value can be prepended and appended with arbitrary strings indicating, for example, currency or the unit of measurement. See setPrefix() and setSuffix(). The text in the spin box is retrieved with text() (which includes any prefix() and suffix()), or with cleanText() (which has no prefix(), no suffix() and no leading or trailing whitespace).

It is often desirable to give the user a special (often default) choice in addition to the range of numeric values. See setSpecialValueText() for how to do this with QDoubleSpinBox.

Note: The displayed value of the QDoubleSpinBox is limited to 18 characters in addition to eventual prefix and suffix content. This limitation is used to keep the double spin box usable even with extremely large values.

This property holds the step value

When the user uses the arrows to change the spin box's value the value will be incremented/decremented by the amount of the singleStep. The default value is 1.0. Setting a singleStep value of less than 0 does nothing.

Access functions:

pub unsafe fn set_step_type(&mut self, step_type: StepType)

Sets the step type for the spin box to stepType, which is single step or adaptive decimal step.

Calls C++ function: void QDoubleSpinBox::setStepType(QAbstractSpinBox::StepType stepType).

C++ documentation:

Sets the step type for the spin box to stepType, which is single step or adaptive decimal step.

Adaptive decimal step means that the step size will continuously be adjusted to one power of ten below the current value. So when the value is 1100, the step is set to 100, so stepping up once increases it to 1200. For 1200 stepping up takes it to 1300. For negative values, stepping down from -1100 goes to -1200.

It also works for any decimal values, 0.041 is increased to 0.042 by stepping once.

Step direction is taken into account to handle edges cases, so that stepping down from 100 takes the value to 99 instead of 90. Thus a step up followed by a step down -- or vice versa -- always lands on the starting value; 99 -> 100 -> 99.

Setting this will cause the spin box to disregard the value of singleStep, although it is preserved so that singleStep comes into effect if adaptive decimal step is later turned off.

This function was introduced in Qt 5.12.

Note: Setter function for property stepType.

See also stepType().

The suffix is appended to the end of the displayed value. Typical use is to display a unit of measurement or a currency symbol. For example:

spinbox->setSuffix(" km");

To turn off the suffix display, set this property to an empty string. The default is no suffix. The suffix is not displayed for the minimum() if specialValueText() is set.

If no suffix is set, suffix() returns an empty string.

QString	suffix() const
void	setSuffix(const QString &suffix)

pub unsafe fn is_read_only(&self) -> bool

This property holds whether the spin box is read only.

Calls C++ function: bool QAbstractSpinBox::isReadOnly() const.

C++ documentation:

This property holds 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.

Access functions:

bool	isReadOnly() const
void	setReadOnly(bool r)

See also QLineEdit::readOnly.

pub unsafe fn keyboard_tracking(&self) -> bool

This property holds whether keyboard tracking is enabled for the spinbox.

Calls C++ function: bool QAbstractSpinBox::keyboardTracking() const.

C++ documentation:

This property holds whether keyboard tracking is enabled for the spinbox.

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.

This property was introduced in Qt 4.3.

Access functions:

bool	keyboardTracking() const
void	setKeyboardTracking(bool kt)

pub unsafe fn set_special_value_text(
    &mut self,
    txt: impl CastInto<Ref<QString>>
)

This property holds the special-value text

Calls C++ function: void QAbstractSpinBox::setSpecialValueText(const QString& txt).

C++ documentation:

This property holds 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.

Access functions:

QString	specialValueText() const
void	setSpecialValueText(const QString &txt)

pub unsafe fn set_wrapping(&mut self, w: bool)

This property holds whether the spin box is circular.

Calls C++ function: void QAbstractSpinBox::setWrapping(bool w).

C++ documentation:

This property holds 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

Access functions:

bool	wrapping() const
void	setWrapping(bool w)

      zoomSpinBox->setSpecialValueText(tr("Automatic"));

pub unsafe fn step_by(&mut self, steps: c_int)
