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.

Constructor & Destructor Documentation

◆ QtDoublePropertyManager()

QtDoublePropertyManager::QtDoublePropertyManager ( QObject * parent = 0)

Creates a manager with the given parent.

◆ ~QtDoublePropertyManager()

QtDoublePropertyManager::~QtDoublePropertyManager ( )

Destroys this manager, and all the properties it has created.

Member Function Documentation

◆ decimals()

int QtDoublePropertyManager::decimals ( const QtProperty * property) const

Returns the given property's precision, in decimals.

See also
setDecimals()

◆ decimalsChanged

void QtDoublePropertyManager::decimalsChanged ( QtProperty * property,
int prec )
signal

This signal is emitted whenever a property created by this manager changes its precision of value, passing a pointer to the property and the new prec value

See also
setDecimals()

◆ initializeProperty()

void QtDoublePropertyManager::initializeProperty ( QtProperty * property)
protectedvirtual

\reimp

Implements QtAbstractPropertyManager.

◆ maximum()

double QtDoublePropertyManager::maximum ( const QtProperty * property) const

Returns the given property's maximum value.

See also
minimum(), setRange()

◆ minimum()

double QtDoublePropertyManager::minimum ( const QtProperty * property) const

Returns the given property's minimum value.

See also
maximum(), setRange()

◆ 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

See also
setRange()

◆ 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.

See also
decimals()

◆ 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()

◆ 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).

See also
minimum(), setRange(), rangeChanged()

◆ 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).

See also
setMinimum(), setMaximum(), rangeChanged()

◆ 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.

See also
singleStep()

◆ setValue

void QtDoublePropertyManager::setValue ( QtProperty * property,
double value )
slot

Sets the value of the given property to value.

If the specified value is not valid according to the given property's range, the value is adjusted to the nearest valid value within the range.

See also
value(), setRange(), valueChanged()

◆ singleStep()

double QtDoublePropertyManager::singleStep ( const QtProperty * property) const

Returns the given property's step value.

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

See also
setSingleStep()

◆ singleStepChanged

void QtDoublePropertyManager::singleStepChanged ( QtProperty * property,
double step )
signal

This signal is emitted whenever a property created by this manager changes its single step property, passing a pointer to the property and the new step value

See also
setSingleStep()

◆ uninitializeProperty()

void QtDoublePropertyManager::uninitializeProperty ( QtProperty * property)
protectedvirtual

\reimp

Reimplemented from QtAbstractPropertyManager.

◆ value()

double QtDoublePropertyManager::value ( const QtProperty * property) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns 0.

See also
setValue()

◆ valueChanged

void QtDoublePropertyManager::valueChanged ( QtProperty * property,
double value )
signal

This signal is emitted whenever a property created by this manager changes its value, passing a pointer to the property and the new value as parameters.

See also
setValue()

◆ valueText()

QString QtDoublePropertyManager::valueText ( const QtProperty * property) const
protectedvirtual

\reimp

Reimplemented from QtAbstractPropertyManager.
