## 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.

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

See also Core::IEditor, Core::IDocument, and Core::EditorManager.

## Member Function Documentation

### 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().

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

Creates an editor.

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

See also setEditorCreator().

### `[static]` const Core::EditorFactoryList IEditorFactory::defaultEditorFactories(const Utils::MimeType &mimeType)

Returns all available editor factories for the mimeType in the default order (editor types ordered by MIME type hierarchy).

### 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 factory.

See also addMimeType() and setMimeTypes().

### `[static]` const Core::EditorFactoryList IEditorFactory::preferredEditorFactories(const QString &fileName)

Returns the available editor factories for fileName 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.

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().
