Injectors
This is an overview of the injection methods supported by GammaRay and their limitations. You can choose which one to use in the QtCreator settings or using the "-i" command line option.
- Architecture: any (tested: x86, ARM)
- Operating System: Linux, QNX
- Limitations: Broken on some Ubuntu systems due to them building Qt the wrong way, see Known Issues.
- Coverage: all QObjects, all connections
- Injection time: startup
- Performance: no impact
- Note: default on Linux for startup injection
- Architecture: any (tested: x86)
- Operating System: Linux, Mac OS X
- Limitations: platform security needs to allow attaching to a process
- Coverage: only QObjects attached to widgets and/or receiving QEvents at runtime, all connections made after attaching
- Injection time: startup, runtime
- Performance: poor during startup/attaching
- Note: default on Linux/Mac for runtime attaching
- Architecture: any (tested: x86)
- Operating System: any (tested Linux, Mac, Windows/MSVC)
- Limitations: interference with custom styles, needs Qt style plugin support to be enabled
- Coverage: only QObjects attached to widgets and/or receiving QEvents at runtime, all connections made after attaching
- Injection time: startup
- Performance: no impact
- Note: only relies on Qt for injection, therefore a good fallback if any of the other injectors fail
- Architecture: x86
- Operating System: Windows
- Limitations: MSVC only in GammaRay 1.0, MingW support added in GammaRay 1.1
- Coverage: all QObjects created after injection (previously created objects are recovered if attached to new objects, widgets or when receiving events), all connections created after injection
- Injection time: startup, runtime
- Performance: no impact
- Note: default on Windows
- Architecture: x86
- Operating System: Mac OS X
- Limitations: see Known Issues regarding usage with app bundles
- Coverage: all QObjects, all connections
- Injection time: startup
- Performance: no impact
- Note: default on Mac
