Solid::DeviceInterface::Type deviceInterfaceType()

Detailed Description

It exposes a set of properties and is organized as a key/value set.

Warning: Using this class could expose some backend specific details and lead to non portable code. Use it at your own risk, or during transitional phases when the provided device interfaces don't provide the necessary methods.

Member Type Documentation

enum GenericInterface::PropertyChange

This enum type defines the type of change that can occur to a GenericInterface property.

ConstantValueDescription
Solid::GenericInterface::PropertyModified0A property value has changed in the device
Solid::GenericInterface::PropertyAdded1A new property has been added to the device
Solid::GenericInterface::PropertyRemoved2A property has been removed from the device

Member Function Documentation

QMap<QString, QVariant> GenericInterface::allProperties() const

Returns a key/value map of all the known properties for the device.

Warning: Using this method could expose some backend specific details and lead to non portable code. Use it at your own risk, or during transitional phases when the provided device interfaces don't provide the necessary methods.

[signal] void GenericInterface::conditionRaised(const QString &condition, const QString &reason)

This signal is emitted when an event occurred in the device. For example when a button is pressed.

Returns the name for the condition of the event and the reason for the condition to have been raised.

[static] Solid::DeviceInterface::Type GenericInterface::deviceInterfaceType()

Returns the Solid::DeviceInterface::Type of the GenericInterface device interface.

See also Solid::DeviceInterface::Type.

QVariant GenericInterface::property(const QString &key) const

Returns the property key of the device, or QVariant() if the property is unknown.

Warning: Using this method could expose some backend specific details and lead to non portable code. Use it at your own risk, or during transitional phases when the provided device interfaces don't provide the necessary methods.

[signal] void GenericInterface::propertyChanged(const QMap<QString, int> &changes)

This signal is emitted when a property is changed in the device.

Returns the map describing the property changes that occurred in the device, keys are property names, and values describe the kind of change done on the device property (added/removed/modified), one of Solid::Device::PropertyChange.

bool GenericInterface::propertyExists(const QString &key) const

Returns whether a property key exists in the device.

Warning: Using this method could expose some backend specific details and lead to non portable code. Use it at your own risk, or during transitional phases when the provided device interfaces don't provide the necessary methods.
