SpinBox

This property holds the textual value of the spinbox.

The value of the property is based on textFromValue and locale, and equal to:

var text = spinBox.textFromValue(spinBox.value, spinBox.locale)

This property was introduced in QtQuick.Controls 2.4 (Qt 5.11).

See also textFromValue.

These properties hold the down indicator item and whether it is pressed or hovered. The down.hovered property was introduced in QtQuick.Controls 2.1, and the down.implicitIndicatorWidth and down.implicitIndicatorHeight properties were introduced in QtQuick.Controls 2.5.

See also decrease().

This property holds whether the spinbox is editable. The default value is false.

See also validator.

This property holds the starting value for the range. The default value is 0.

See also to and value.

This property holds whether an editable spin box has partial text input from an input method.

While it is composing, an input method may rely on mouse or key events from the spin box to edit or commit the partial text. This property can be used to determine when to disable event handlers that may interfere with the correct operation of an input method.

This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

This property provides hints to the input method about the expected content of the spin box and how it should operate.

The default value is Qt.ImhDigitsOnly.

The value is a bit-wise combination of flags or Qt.ImhNone if no hints are set.

Flags that alter behavior are:

• Qt.ImhHiddenText - Characters should be hidden, as is typically used when entering passwords.
• Qt.ImhSensitiveData - Typed text should not be stored by the active input method in any persistent storage like predictive user dictionary.
• Qt.ImhNoAutoUppercase - The input method should not try to automatically switch to upper case when a sentence ends.
• Qt.ImhPreferNumbers - Numbers are preferred (but not required).
• Qt.ImhPreferUppercase - Upper case letters are preferred (but not required).
• Qt.ImhPreferLowercase - Lower case letters are preferred (but not required).
• Qt.ImhNoPredictiveText - Do not use predictive text (i.e. dictionary lookup) while typing.
• Qt.ImhDate - The text editor functions as a date field.
• Qt.ImhTime - The text editor functions as a time field.

Flags that restrict input (exclusive flags) are:

• Qt.ImhDigitsOnly - Only digits are allowed.
• Qt.ImhFormattedNumbersOnly - Only number input is allowed. This includes decimal point and minus sign.
• Qt.ImhUppercaseOnly - Only upper case letter input is allowed.
• Qt.ImhLowercaseOnly - Only lower case letter input is allowed.
• Qt.ImhDialableCharactersOnly - Only characters suitable for phone dialing are allowed.
• Qt.ImhEmailCharactersOnly - Only characters suitable for email addresses are allowed.
• Qt.ImhUrlCharactersOnly - Only characters suitable for URLs are allowed.

Masks:

• Qt.ImhExclusiveInputMask - This mask yields nonzero if any of the exclusive flags are used.

This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

This property holds the step size. The default value is 1.

This property holds a callback function that is called whenever an integer value needs to be converted to display text.

The default function can be overridden to display custom text for a given value. This applies to both editable and non-editable spinboxes; for example, when using the up and down buttons or a mouse wheel to increment and decrement the value, the new value is converted to display text using this function.

The callback function signature is string function(value, locale). The function can have one or two arguments, where the first argument is the value to be converted, and the optional second argument is the locale that should be used for the conversion, if applicable.

The default implementation does the conversion using Number.toLocaleString():

textFromValue: function(value, locale) { return Number(value).toLocaleString(locale, 'f', 0); }

See also valueFromText, validator, and locale.

This property holds the end value for the range. The default value is 99.

See also from and value.

These properties hold the up indicator item and whether it is pressed or hovered. The up.hovered property was introduced in QtQuick.Controls 2.1, and the up.implicitIndicatorWidth and up.implicitIndicatorHeight properties were introduced in QtQuick.Controls 2.5.

See also increase().

This property holds the input text validator for editable spinboxes. By default, SpinBox uses IntValidator to accept input of integer numbers.

SpinBox {
    id: control
    validator: IntValidator {
        locale: control.locale.name
        bottom: Math.min(control.from, control.to)
        top: Math.max(control.from, control.to)
    }
}

This property holds the value in the range from - to. The default value is 0.

This property holds a callback function that is called whenever input text needs to be converted to an integer value.

This function only needs to be overridden when textFromValue is overridden for an editable spinbox.

The callback function signature is int function(text, locale). The function can have one or two arguments, where the first argument is the text to be converted, and the optional second argument is the locale that should be used for the conversion, if applicable.

The default implementation does the conversion using Number.fromLocaleString():

valueFromText: function(text, locale) { return Number.fromLocaleString(locale, text); }

See also textFromValue, validator, and locale.

This property holds whether the spinbox wraps. The default value is false.

If wrap is true, stepping past to changes the value to from and vice versa.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

This signal is emitted when the spin box value has been interactively modified by the user by either touch, mouse, wheel, or keys. In the case of interaction via keyboard, the signal is only emitted when the text has been accepted; meaning when the enter or return keys are pressed, or the input field loses focus.

Note: The corresponding handler is onValueModified.

This signal was introduced in QtQuick.Controls 2.2 (Qt 5.9).

Decreases the value by stepSize, or 1 if stepSize is not defined.

Increases the value by stepSize, or 1 if stepSize is not defined.
