Detailed Description

Whenever a user wants to edit or create a document, the EditorManager scans all IEditorFactory instances for suitable editors. The selected IEditorFactory is then asked to create an editor.

Implementations should set the properties of the IEditorFactory subclass in their constructor with IEditorFactory::setId(), IEditorFactory::setDisplayName(), IEditorFactory::setMimeTypes(), and setEditorCreator()

IEditorFactory instances automatically register themselves in Qt Creator in their constructor.

There are two varieties of editors: Internal and external. Internal editors open within the main editing area of Qt Creator. An IEditorFactory defines an internal editor by using the setEditorCreator function. External editors are external applications and are defined by using the setEditorStarter function. They are accessible by the user using the Open With dialog

Member Function Documentation

[protected] IEditorFactory::IEditorFactory()

Creates an IEditorFactory.

Registers the IEditorFactory in Qt Creator.

[protected] void IEditorFactory::addMimeType(const QString &mimeType)

Adds mimeType to the list of MIME types supported by this editor type.

See also mimeTypes() and setMimeTypes().

[static] const Core::EditorFactories IEditorFactory::allEditorFactories()

Returns all registered internal and external editors.

Core::IEditor *IEditorFactory::createEditor() const

Creates an internal editor.

Uses the function set with setEditorCreator() to create the editor.

See also setEditorCreator().

[static] const Core::EditorFactories IEditorFactory::defaultEditorFactories(const Utils::MimeType &mimeType)

Returns all available internal and external editors for the mimeType in the default order: Editor types ordered by MIME type hierarchy, internal editors first.

QString IEditorFactory::displayName() const

Returns a user-visible description of the editor type.

See also setDisplayName().

Utils::Id IEditorFactory::id() const

Returns the ID of the editors' document type.

See also setId().

QStringList IEditorFactory::mimeTypes() const

Returns the list of supported MIME types of this editor type.

See also addMimeType() and setMimeTypes().

[static] const Core::EditorFactories IEditorFactory::preferredEditorFactories(const Utils::FilePath &filePath)

Returns the available editor factories for filePath in order of preference. That is the default order for the document's MIME type but with a user overridden default editor first, and the binary editor as the very first item if a text document is too large to be opened as a text file.

[protected] void IEditorFactory::setDisplayName(const QString &displayName)

Sets the displayName of the editor type. This is for example shown in the Open With menu and the MIME type preferences.

See also displayName().

[protected] void IEditorFactory::setEditorCreator(const std::function<IEditor *()> &creator)

Sets the function that is used to create an editor instance in createEditor() to creator.

This is mutually exclusive with the use of setEditorStarter.

See also createEditor().

[protected] void IEditorFactory::setId(Utils::Id id)

Sets the id of the editors' document type. This must be the same as the IDocument::id() of the documents returned by created editors.

See also id().

[protected] void IEditorFactory::setMimeTypes(const QStringList &mimeTypes)

Sets the MIME types supported by the editor type to mimeTypes.

See also addMimeType() and mimeTypes().

bool IEditorFactory::startEditor(const Utils::FilePath &filePath, QString *errorMessage)

Starts an external editor.

Uses the function set with setEditorStarter() to start the editor.

See also setEditorStarter().
