Detailed Description
Debug messages are usually created by the OpenGL server and then read by OpenGL clients (either from the OpenGL internal debug log, or logged in real-time). A debug message has a textual representation, a vendor-specific numeric id, a source, a type and a severity.
It's also possible for applications or third-party libraries and toolkits to create and insert messages in the debug log. In order to do so, you can use the createApplicationMessage() or the createThirdPartyMessage() static functions.
See also QOpenGLDebugLogger.
Member Type Documentation
enum QOpenGLDebugMessage::Severity
flags QOpenGLDebugMessage::Severities
The Severity enum defines the severity of the debug message.
| Constant | Value | Description |
|---|---|---|
QOpenGLDebugMessage::InvalidSeverity | 0x00000000 | The severity of the message is invalid; this is the severity of a default-constructed QOpenGLDebugMessage object. |
QOpenGLDebugMessage::HighSeverity | 0x00000001 | The message has a high severity. |
QOpenGLDebugMessage::MediumSeverity | 0x00000002 | The message has a medium severity. |
QOpenGLDebugMessage::LowSeverity | 0x00000004 | The message has a low severity. |
QOpenGLDebugMessage::NotificationSeverity | 0x00000008 | The message is a notification. |
QOpenGLDebugMessage::AnySeverity | 0xffffffff | This value corresponds to a mask of all possible message severities. |
The Severities type is a typedef for QFlags<Severity>. It stores an OR combination of Severity values.
enum QOpenGLDebugMessage::Source
flags QOpenGLDebugMessage::Sources
The Source enum defines the source of the debug message.
| Constant | Value | Description |
|---|---|---|
QOpenGLDebugMessage::InvalidSource | 0x00000000 | The source of the message is invalid; this is the source of a default-constructed QOpenGLDebugMessage object. |
QOpenGLDebugMessage::APISource | 0x00000001 | The message was generated in response to OpenGL API calls. |
QOpenGLDebugMessage::WindowSystemSource | 0x00000002 | The message was generated by the window system. |
QOpenGLDebugMessage::ShaderCompilerSource | 0x00000004 | The message was generated by the shader compiler. |
QOpenGLDebugMessage::ThirdPartySource | 0x00000008 | The message was generated by a third party, for instance an OpenGL framework a or debugging toolkit. |
QOpenGLDebugMessage::ApplicationSource | 0x00000010 | The message was generated by the application itself. |
QOpenGLDebugMessage::OtherSource | 0x00000020 | The message was generated by a source not included in this enumeration. |
QOpenGLDebugMessage::AnySource | 0xffffffff | This value corresponds to a mask of all possible message sources. |
The Sources type is a typedef for QFlags<Source>. It stores an OR combination of Source values.
enum QOpenGLDebugMessage::Type
flags QOpenGLDebugMessage::Types
The Type enum defines the type of the debug message.
| Constant | Value | Description |
|---|---|---|
QOpenGLDebugMessage::InvalidType | 0x00000000 | The type of the message is invalid; this is the type of a default-constructed QOpenGLDebugMessage object. |
QOpenGLDebugMessage::ErrorType | 0x00000001 | The message represents an error. |
QOpenGLDebugMessage::DeprecatedBehaviorType | 0x00000002 | The message represents an usage of deprecated behavior. |
QOpenGLDebugMessage::UndefinedBehaviorType | 0x00000004 | The message represents an usage of undefined behavior. |
QOpenGLDebugMessage::PortabilityType | 0x00000008 | The message represents an usage of vendor-specific behavior, that might pose portability concerns. |
QOpenGLDebugMessage::PerformanceType | 0x00000010 | The message represents a performance issue. |
QOpenGLDebugMessage::OtherType | 0x00000020 | The message represents a type not included in this enumeration. |
QOpenGLDebugMessage::MarkerType | 0x00000040 | The message represents a marker in the debug log. |
QOpenGLDebugMessage::GroupPushType | 0x00000080 | The message represents a debug group push operation. |
QOpenGLDebugMessage::GroupPopType | 0x00000100 | The message represents a debug group pop operation. |
QOpenGLDebugMessage::AnyType | 0xffffffff | This value corresponds to a mask of all possible message types. |
The Types type is a typedef for QFlags<Type>. It stores an OR combination of Type values.
Member Function Documentation
QOpenGLDebugMessage::QOpenGLDebugMessage()
Constructs a debug message with an empty message string, id set to 0, source set to InvalidSource, type set to InvalidType, and severity set to InvalidSeverity.
Note: This constructor should not be used to create a debug message; instead, use the createApplicationMessage() or the createThirdPartyMessage() static functions.
See also createApplicationMessage() and createThirdPartyMessage().
QOpenGLDebugMessage::QOpenGLDebugMessage(const QOpenGLDebugMessage &debugMessage)
Constructs a debug message as a copy of debugMessage.
See also operator=().
[noexcept] QOpenGLDebugMessage::~QOpenGLDebugMessage()
Destroys this debug message.
[static] QOpenGLDebugMessage QOpenGLDebugMessage::createApplicationMessage(const QString &text, GLuint id = 0, QOpenGLDebugMessage::Severity severity = NotificationSeverity, QOpenGLDebugMessage::Type type = OtherType)
Constructs and returns a debug message with text as its text, id as id, severity as severity, and type as type. The message source will be set to ApplicationSource.
See also QOpenGLDebugLogger::logMessage() and createThirdPartyMessage().
[static] QOpenGLDebugMessage QOpenGLDebugMessage::createThirdPartyMessage(const QString &text, GLuint id = 0, QOpenGLDebugMessage::Severity severity = NotificationSeverity, QOpenGLDebugMessage::Type type = OtherType)
Constructs and returns a debug message with text as its text, id as id, severity as severity, and type as type. The message source will be set to ThirdPartySource.
See also QOpenGLDebugLogger::logMessage() and createApplicationMessage().
GLuint QOpenGLDebugMessage::id() const
Returns the id of the debug message. Ids are generally vendor-specific.
QString QOpenGLDebugMessage::message() const
Returns the textual message contained by this debug message.
QOpenGLDebugMessage::Severity QOpenGLDebugMessage::severity() const
Returns the severity of the debug message.
QOpenGLDebugMessage::Source QOpenGLDebugMessage::source() const
Returns the source of the debug message.
[noexcept] void QOpenGLDebugMessage::swap(QOpenGLDebugMessage &debugMessage)
Swaps the message debugMessage with this message. This operation is very fast and never fails.
QOpenGLDebugMessage::Type QOpenGLDebugMessage::type() const
Returns the type of the debug message.
bool QOpenGLDebugMessage::operator!=(const QOpenGLDebugMessage &debugMessage) const
Returns true if this message is different from debugMessage, or false otherwise.
See also operator==().
[noexcept] QOpenGLDebugMessage &QOpenGLDebugMessage::operator=(QOpenGLDebugMessage &&debugMessage)
Move-assigns debugMessage to this object.
QOpenGLDebugMessage &QOpenGLDebugMessage::operator=(const QOpenGLDebugMessage &debugMessage)
Assigns the message debugMessage to this object, and returns a reference to the copy.
bool QOpenGLDebugMessage::operator==(const QOpenGLDebugMessage &debugMessage) const
Returns true if this debug message is equal to debugMessage, or false otherwise. Two debugging messages are equal if they have the same textual message, the same id, the same source, the same type and the same severity.
See also operator!=().
