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.

enum QOpenGLDebugMessage::Severity
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. |
enum QOpenGLDebugMessage::Source
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. |
enum QOpenGLDebugMessage::Type
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. |
