List of all members, including inherited members

#Public Types

• enum KNumberModel::Roles

#Properties

• formattingOptions : QLocale::NumberOptions
• maximumValue : qreal
• minimumValue : qreal
• stepSize : qreal

#Public Functions

• KNumberModel(QObject *parent = nullptr)
• qreal value(const QModelIndex &index) const

#Detailed Description

The model contains two roles:

• display - the number represented as a string
• value - the actual value as a number

#Member Type Documentation

#enum KNumberModel::Roles

KNumberModel::ValueRole	Qt::UserRole

#Property Documentation

#formattingOptions : QLocale::NumberOptions

Defines the string representation of the number, e.g. "1,000" or "1000".

Default is QLocale::Default.

Access functions:

• QLocale::NumberOptions formattingOptions() const
• void setFormattingOptions(QLocale::NumberOptions options)

Notifier signal:

• void formattingOptionsChanged()

#maximumValue : qreal

The maximum value for the model

The default value is 0.0.

Note: If maximumValue is a multiple of stepSize added to minimumValue it will be included. Otherwise it will not be reached. E.g. in a model with a minimumValue of 0.0, a maximumValue of 1.0 and a stepSize of 0.3, the final row will be 0.9.

Access functions:

• qreal maximumValue() const
• void setMaximumValue(qreal maximumValue)

Notifier signal:

• void maximumValueChanged()

#minimumValue : qreal

The minimum value for the model

The default value is 0.0.

Access functions:

• qreal minimumValue() const
• void setMinimumValue(qreal minimumValue)

Notifier signal:

• void minimumValueChanged()

#stepSize : qreal

Step between listed entries

The default value is 1.0.

Access functions:

• qreal stepSize() const
• void setStepSize(qreal stepSize)

Notifier signal:

• void stepSizeChanged()
