Property Documentation

bool QRangeModel::inverted

readwrite

the model is inverted or not

The model can be represented with an inverted behavior, e.g. when value assumes the maximum value (represented by maximumValue) the position will be at its minimum (represented by positionAtMinimum).

Definition at line 62 of file qrangemodel.h.

QRangeModel::maximumValue

readwrite

the maximum value that value can assume

This property's default value is 99

Definition at line 57 of file qrangemodel.h.

QRangeModel::minimumValue

readwrite

the minimum value that value can assume

This property's default value is 0

Definition at line 56 of file qrangemodel.h.

qreal QRangeModel::position

readwrite

the current position of the model

Represents a valid external position, based on the positionAtMinimum, positionAtMaximum and the stepSize properties. The user can set it internally with a position, that is not within the current position range, since it can become valid if the user changes the position range later.

Definition at line 59 of file qrangemodel.h.

qreal QRangeModel::positionAtMaximum

readwrite

the maximum value that position can assume

This property's default value is 0

Definition at line 61 of file qrangemodel.h.

qreal QRangeModel::positionAtMinimum

readwrite

the minimum value that position can assume

This property's default value is 0

Definition at line 60 of file qrangemodel.h.

qreal QRangeModel::stepSize

readwrite

the value that is added to the value and position property

Example: If a user sets a range of [0,100] and stepSize to 30, the valid values that are going to be seen externally would be: 0, 30, 60, 90, 100.

Definition at line 58 of file qrangemodel.h.

qreal QRangeModel::value

readwrite

the current value of the model

Represents a valid external value, based on the minimumValue, maximumValue and the stepSize properties. The user can set it internally with a value, that is not within the current range, since it can become valid if the user changes the range later.
