Detailed Description

The QtIntPropertyManager provides and manages int properties.

An int 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, QtIntPropertyManager 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.

See also QtAbstractPropertyManager, QtSpinBoxFactory, QtSliderFactory, and QtScrollBarFactory.

Member Function Documentation

QtIntPropertyManager::QtIntPropertyManager ( QObject * parent = 0 )

Creates a manager with the given parent.

QtIntPropertyManager::~QtIntPropertyManager ()

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

int QtIntPropertyManager::maximum ( const QtProperty * property ) const

Returns the given property's maximum value.

See also setMaximum(), minimum(), and setRange().

int QtIntPropertyManager::minimum ( const QtProperty * property ) const

Returns the given property's minimum value.

See also setMinimum(), maximum(), and setRange().

void QtIntPropertyManager::rangeChanged ( QtProperty * property, int minimum, int 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().

void QtIntPropertyManager::setMaximum ( QtProperty * property, int maxVal )   [slot]

Sets the maximum value for the given property to maxVal.

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

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

void QtIntPropertyManager::setMinimum ( QtProperty * property, int 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 the range).

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

void QtIntPropertyManager::setRange ( QtProperty * property, int minimum, int 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(), and rangeChanged().

void QtIntPropertyManager::setSingleStep ( QtProperty * property, int 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().

void QtIntPropertyManager::setValue ( QtProperty * property, int 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(), and valueChanged().

int QtIntPropertyManager::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().

void QtIntPropertyManager::singleStepChanged ( QtProperty * property, int 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().

int QtIntPropertyManager::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().

void QtIntPropertyManager::valueChanged ( QtProperty * property, int 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().
