Detailed Description
The model contains two roles:
- display - the number represented as a string
- value - the actual value as a number
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 1.0.
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 1.0.
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() |

qreal KNumberModel::value(const QModelIndex &index) const
