Detailed Description
The plugin spec is also filled with more information as the plugin goes through its loading process (see PluginSpec::State). If an error occurs, the plugin spec is the place to look for the error details.
Member Type Documentation
enum PluginSpec::State
The State enum indicates the states the plugin goes through while it is being loaded.
The state gives a hint on what went wrong in case of an error.
| Constant | Value | Description |
|---|---|---|
ExtensionSystem::PluginSpec::Invalid | 0 | Starting point: Even the plugin meta data was not read. |
ExtensionSystem::PluginSpec::Read | 1 | The plugin meta data has been successfully read, and its information is available via the PluginSpec. |
ExtensionSystem::PluginSpec::Resolved | 2 | The dependencies given in the description file have been successfully found, and are available via the dependencySpecs() function. |
ExtensionSystem::PluginSpec::Loaded | 3 | The plugin's library is loaded and the plugin instance created (available through plugin()). |
ExtensionSystem::PluginSpec::Initialized | 4 | The plugin instance's IPlugin::initialize() function has been called and returned a success value. |
ExtensionSystem::PluginSpec::Running | 5 | The plugin's dependencies are successfully initialized and extensionsInitialized has been called. The loading process is complete. |
ExtensionSystem::PluginSpec::Stopped | 6 | The plugin has been shut down, i.e. the plugin's IPlugin::aboutToShutdown() function has been called. |
ExtensionSystem::PluginSpec::Deleted | 7 | The plugin instance has been deleted. |
Member Function Documentation
[virtual] void PluginSpec::addArgument(const QString &argument)
Adds argument to the command line arguments specific to the plugin.
[virtual] ExtensionSystem::PluginSpec::PluginArgumentDescriptions PluginSpec::argumentDescriptions() const
Returns a list of descriptions of command line arguments the plugin processes.
[virtual] QStringList PluginSpec::arguments() const
Returns command line arguments specific to the plugin. Set at startup.
See also setArguments().
[virtual] QString PluginSpec::category() const
Returns the category that the plugin belongs to. Categories are used to group plugins together in the UI. Returns an empty string if the plugin does not belong to a category.
[virtual] QString PluginSpec::compatVersion() const
Returns the plugin compatibility version. This is valid after the PluginSpec::Read state is reached.
[virtual] QString PluginSpec::copyright() const
Returns the plugin copyright. This is valid after the PluginSpec::Read state is reached.
[virtual] QVector<ExtensionSystem::PluginDependency> PluginSpec::dependencies() const
The plugin dependencies. This is valid after the PluginSpec::Read state is reached.
[virtual] QHash<ExtensionSystem::PluginDependency, ExtensionSystem::PluginSpec *> PluginSpec::dependencySpecs() const
Returns the list of dependencies, already resolved to existing plugin specs. Valid if PluginSpec::Resolved state is reached.
See also PluginSpec::dependencies().
[virtual] QString PluginSpec::description() const
Returns the plugin description. This is valid after the PluginSpec::Read state is reached.
[virtual] QString PluginSpec::errorString() const
Returns a detailed, possibly multi-line, error description in case of an error.
[virtual] Utils::FilePath PluginSpec::filePath() const
Returns the absolute path to the plugin.
[virtual] bool PluginSpec::hasError() const
Returns whether an error occurred while reading or starting the plugin.
[virtual] bool PluginSpec::isAvailableForHostPlatform() const
Returns whether the plugin works on the host platform.
[virtual] bool PluginSpec::isDeprecated() const
Returns whether the plugin has its deprecated flag set.
[virtual] bool PluginSpec::isEffectivelyEnabled() const
Returns whether the plugin is loaded at startup.
See also isEnabledBySettings().
[virtual] bool PluginSpec::isEnabledByDefault() const
Returns whether the plugin is enabled by default. A plugin might be disabled because the plugin is experimental or deprecated, or because the installation settings define it as disabled by default.
[virtual] bool PluginSpec::isEnabledBySettings() const
Returns whether the plugin should be loaded at startup, taking into account the default enabled state, and the user's settings.
Note: This function might return false even if the plugin is loaded as a requirement of another enabled plugin.
See also isEffectivelyEnabled().
[virtual] bool PluginSpec::isEnabledIndirectly() const
Returns true if loading was not done due to user unselecting this plugin or its dependencies.
[virtual] bool PluginSpec::isExperimental() const
Returns whether the plugin has its experimental flag set.
[virtual] bool PluginSpec::isForceDisabled() const
Returns whether the plugin is disabled via the -noload option on the command line.
[virtual] bool PluginSpec::isForceEnabled() const
Returns whether the plugin is enabled via the -load option on the command line.
[virtual] bool PluginSpec::isRequired() const
Returns whether the plugin is required.
[virtual] bool PluginSpec::isSoftLoadable() const
Returns whether the plugin is allowed to be loaded during runtime without a restart.
[virtual] QString PluginSpec::license() const
Returns the plugin license. This is valid after the PluginSpec::Read state is reached.
[virtual] Utils::FilePath PluginSpec::location() const
Returns the absolute path to the directory containing the plugin.
[virtual] QString PluginSpec::longDescription() const
Returns the plugin's long description. This is valid after the PluginSpec::Read state is reached.
[virtual] QJsonObject PluginSpec::metaData() const
Returns the plugin meta data.
[virtual] QString PluginSpec::name() const
Returns the plugin name. This is valid after the PluginSpec::Read state is reached.
[virtual, since 3.0] QRegularExpression PluginSpec::platformSpecification() const
Returns a QRegularExpression matching the platforms this plugin works on. An empty pattern implies all platforms.
This function was introduced in Qt 3.0.
[virtual] bool PluginSpec::provides(ExtensionSystem::PluginSpec *spec, const ExtensionSystem::PluginDependency &dependency) const
Returns whether the plugin spec can be used to fill the dependency of this plugin.
See also PluginSpec::dependencies().
[virtual] bool PluginSpec::requiresAny(const QSet<ExtensionSystem::PluginSpec *> &plugins) const
Returns whether the plugin requires any of the plugins specified by plugins.
[virtual] void PluginSpec::setArguments(const QStringList &arguments)
Sets the command line arguments specific to the plugin to arguments.
See also arguments().
[virtual] void PluginSpec::setEnabledBySettings(bool value)
Sets whether the plugin should be loaded at startup to value.
See also isEnabledBySettings().
[virtual] ExtensionSystem::PluginSpec::State PluginSpec::state() const
Returns the state in which the plugin currently is. See the description of the PluginSpec::State enum for details.
[virtual] QString PluginSpec::url() const
Returns the plugin URL where you can find more information about the plugin. This is valid after the PluginSpec::Read state is reached.
[virtual] QString PluginSpec::vendor() const
Returns the plugin vendor. This is valid after the PluginSpec::Read state is reached.
