Detailed Description

The QtDoublePropertyManager provides and manages double properties.

A double property has a current value, and a range specifying the valid values. The range is defined by a minimum and a maximum value.

The property's value and range can be retrieved using the value(), minimum() and maximum() functions, and can be set using the setValue(), setMinimum() and setMaximum() slots. Alternatively, the range can be defined in one go using the setRange() slot.

In addition, QtDoublePropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes, and the rangeChanged() signal which is emitted whenever such a property changes its range of valid values.

+ Here is the caller graph for this function:

◆ rangeChanged

void QtDoublePropertyManager::rangeChanged ( QtProperty property,
double  minimum,
double  maximum 
)
signal

This signal is emitted whenever a property created by this manager changes its range of valid values, passing a pointer to the property and the new minimum and maximum values

signal

Referenced by setReadOnly().

+ Here is the caller graph for this function:

◆ setDecimals

void QtDoublePropertyManager::setDecimals ( QtProperty property,
int  prec 
)
slot

Sets the precision of the given property to prec.

The valid decimal range is 0-13. The default is 2.

+ Here is the caller graph for this function:

◆ setMaximum

void QtDoublePropertyManager::setMaximum ( QtProperty property,
double  maxVal 
)
slot

Sets the maximum value for the given property to maxVal.

When setting the maximum value, the minimum and current values are adjusted if necessary (ensuring that the range remains valid and that the current value is within in the range).

See also
maximum(), setRange(), rangeChanged()

References QtAbstractPropertyManager::propertyChanged(), rangeChanged(), and valueChanged().

◆ setMinimum

void QtDoublePropertyManager::setMinimum ( QtProperty property,
double  minVal 
)
slot

Sets the minimum value for the given property to minVal.

When setting the minimum value, the maximum and current values are adjusted if necessary (ensuring that the range remains valid and that the current value is within in the range).

+ Here is the caller graph for this function:

◆ setRange

void QtDoublePropertyManager::setRange ( QtProperty property,
double  minimum,
double  maximum 
)
slot

Sets the range of valid values.

This is a convenience function defining the range of valid values in one go; setting the minimum and maximum values for the given property with a single function call.

When setting a new range, the current value is adjusted if necessary (ensuring that the value remains within range).

slot

◆ setSingleStep

void QtDoublePropertyManager::setSingleStep ( QtProperty property,
double  step 
)
slot

Sets the step value for the given property to step.

The step is typically used to increment or decrement a property value while pressing an arrow key.

◆ setValue

void QtDoublePropertyManager::setValue ( QtProperty property,
