Member Function Documentation

QCameraControl::QCameraControl ( QCameraControl::CanonicalName canonicalName, quint32 id, QString & description, int min, int max, int step, int defaultValueIndex, QStringList & valueStrings, QCameraControl::GUIElement guiElement, QString customName = QString() )

The parameter given by canonicalName holds a common indentifier to a canonical setting e.g Brightness. If a control has no canonical name e.g the control is a custom device filter for Sharpness then customName provides a description string to it. Parameter id must be a unique identifier that is control specific. The parameter description is a user readable string in a GUI context. The control takes values between [ min and max in stride length step The value defaultValueIndex holds the initial default index. If the control represents a a multiple choice option then valueStrings holds the user readable strings that are parameterized by the values in the range [min, max]. The GUI element that represents this control e.g Slider,Combobox is given by guiElement
