Public Functions

explicit ExtensionPlugin(QObject *parent = nullptr)#

~ExtensionPlugin() override#

virtual QString name() const = 0#: The name of the extension plugin, will be displayed in the user interface.

virtual QString description() const = 0#: A description of the extension plugin, may be displayed in the user interface.

virtual QList<QAction*> actions() const = 0#

Returns:: The QActions for this extension (should be at least one).

virtual QStringList menuPath(QAction *action = nullptr) const = 0#

Returns:: The menu path of the supplied action. This can be empty if the action was not recognized, or contain two or more strings (top level, plus name, e.g. File, &Open).

virtual QList<Io::FileFormat*> fileFormats() const#

The caller takes ownership of the objects in the returned list.

Returns:: A list of file format readers/writers.

Public Slots

virtual void setMolecule(QtGui::Molecule *mol) = 0#: Called when the current molecule changes.

virtual bool readMolecule(QtGui::Molecule &mol)#

Call this slot when the moleculeReady signal indicated that a molecule is ready to be read. The molecule will have the data read into it. The slot will

Returns:: true if a molecule was successfully read in.

virtual void setScene(Rendering::Scene *scene)#: Called when the current scene changes.

virtual void setCamera(Rendering::Camera *camera)#: Called when the active camera for the view changes.

virtual void setActiveWidget(QWidget *widget)#: Called when the active widget changes. This must be used carefully, and should check that the widget has been cast if used.

Signals

void moleculeReady(int numberOfMolecules)#: Signal that the extension has a new molecule that is ready to be loaded. The application must call readMolecule in order to actually read the molecule(s).

void fileFormatsReady()#: Signal that the extension has file formats that are ready to be registered. If emitted the application should call fileFormats to get the formats the extension is registering.

void requestActiveTool(QString toolName)#: Signal to request a particular tool is set as the active tool. This is useful when loading a structure outside of the normal file API and setting “Navigator” to active instead of “Editor” (the default).

void requestActiveDisplayTypes(QStringList displayTypes)#: Request a specific display type (or types) are active, and all others are disabled. This can be useful when loading a specific type of data that would be most readily viewed with a specialized view.
