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.
QtDoublePropertyManager | ( | QObject * | parent = nullptr | ) |
Creates a manager with the given parent.
Destroys this manager, and all the properties it has created.
int decimals | ( | const QtProperty * | property | ) | const |
Returns the given property's precision, in decimals.
|
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
|
protectedvirtual |
This function is called whenever a new valid property pointer has been created, passing the pointer as parameter.
The purpose is to let the manager know that the property has been created so that it can provide additional attributes for the new property, e.g. QtIntPropertyManager adds {QtIntPropertyManager::value()}{value}, {QtIntPropertyManager::minimum()}{minimum} and {QtIntPropertyManager::maximum()}{maximum} attributes. Since each manager subclass adds type specific attributes, this function is pure virtual and must be reimplemented when deriving from the QtAbstractPropertyManager class.
Implements QtAbstractPropertyManager.
double maximum | ( | const QtProperty * | property | ) | const |
Returns the given property's maximum value.
double minimum | ( | const QtProperty * | property | ) | const |
Returns the given property's minimum value.
|
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
|
slot |
Sets the precision of the given property to prec.
The valid decimal range is 0-13. The default is 2.
|
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).
|
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).
|
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 |
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.
|
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.
double 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.
|
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
|
protectedvirtual |
This function is called just before the specified property is destroyed.
The purpose is to let the property manager know that the property is being destroyed so that it can remove the property's additional attributes.
Reimplemented from QtAbstractPropertyManager.
double 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.
|
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.
|
protectedvirtual |
Returns a string representing the current state of the given property.
The default implementation of this function returns an empty string.
Reimplemented from QtAbstractPropertyManager.
