Detailed Description

This class allows the application that embeds the KTextEditor component to allow it access to application wide information and interactions.

For example the component can get the current active main window of the application.

The application must pass a pointer to the Application object to the setApplication method of the global editor instance and ensure that this object stays valid for the complete lifetime of the editor.

It must not reimplement this class but construct an instance and pass a pointer to a QObject that has the required slots to receive the requests.

KTextEditor::Editor::instance()->application() will always return a non-nullptr object to avoid the need for nullptr checks before calling the API.

The same holds for activeMainWindow(), even if no main window is around, you will get a non-nullptr interface object that allows to call the functions of the MainWindow without needs for a nullptr check around it in the client code.

Constructor & Destructor Documentation

Application()

KTextEditor::Application::Application

(

QObject *

parent

)

Construct an Application wrapper object.

The passed parent is both the parent of this QObject and the receiver of all interface calls via invokeMethod.

Parameters

parent

object the calls are relayed to

Definition at line 15 of file application.cpp.

~Application()

KTextEditor::Application::~Application ( )

overridedefault

Virtual Destructor.

Member Function Documentation

activeMainWindow()

KTextEditor::MainWindow * KTextEditor::Application::activeMainWindow

(

)

Accessor to the active main window.

Returns

a pointer to the active mainwindow, even if no main window is active you will get a non-nullptr dummy interface that allows you to call interface functions without the need for null checks

Definition at line 40 of file application.cpp.

closeDocument()

bool KTextEditor::Application::closeDocument

(

KTextEditor::Document *

document

)

Close the given document.

If the document is modified, user will be asked if he wants that.

Parameters

document

the document to be closed

Returns

true on success, otherwise false

Definition at line 79 of file application.cpp.

closeDocuments()

bool KTextEditor::Application::closeDocuments

(

const QList< KTextEditor::Document * > &

documents

)

Close a list of documents.

If any of them are modified, user will be asked if he wants that. Use this, if you want to close multiple documents at once, as the application might be able to group the "do you really want that" dialogs into one.

Parameters

documents

list of documents to be closed

Returns

true on success, otherwise false

Definition at line 87 of file application.cpp.

documentCreated

void KTextEditor::Application::documentCreated ( KTextEditor::Document * document )

signal

This signal is emitted when the document was created.

Parameters

document

document that was created

documentDeleted

void KTextEditor::Application::documentDeleted ( KTextEditor::Document * document )

signal

This signal is emitted when the document has been deleted.

Warning

Do not access the data referenced by the pointer, it is already invalid. Use the pointer only to remove mappings in hash or maps

Parameters

document

document that is deleted

documents()

QList< KTextEditor::Document * > KTextEditor::Application::documents

(

)

Get a list of all documents that are managed by the application.

This might contain less documents than the editor has in his documents () list.

Returns

all documents the application manages, might be empty!

Definition at line 50 of file application.cpp.

documentWillBeDeleted

void KTextEditor::Application::documentWillBeDeleted ( KTextEditor::Document * document )

signal

This signal is emitted before a document which should be closed is deleted The document is still accessible and usable, but it will be deleted after this signal was send.

Parameters

document

document that will be deleted

findUrl()

KTextEditor::Document * KTextEditor::Application::findUrl

(

const QUrl &

url

)

Get the document with the URL url.

if multiple documents match the searched url, return the first found one...

Parameters

url	the document's URL

Returns

the document with the given url or nullptr, if none found

Definition at line 58 of file application.cpp.

mainWindows()

QList< KTextEditor::MainWindow * > KTextEditor::Application::mainWindows

(

)

Get a list of all main windows.

Returns

all main windows, might be empty!

Definition at line 32 of file application.cpp.

openUrl()

KTextEditor::Document * KTextEditor::Application::openUrl	(	const QUrl &	url,
		const QString &	encoding = QString() )

Open the document url with the given encoding.

if the url is empty, a new empty document will be created

Parameters

url	the document's url
encoding	the preferred encoding. If encoding is QString() the encoding will be guessed or the default encoding will be used.

Returns

a pointer to the created document

Definition at line 66 of file application.cpp.

plugin()

KTextEditor::Plugin * KTextEditor::Application::plugin

(

const QString &

name

)

Get a plugin for the plugin with with identifier name.

Parameters

name	the plugin's name

Returns

pointer to the plugin if a plugin with name is loaded, otherwise nullptr

Definition at line 95 of file application.cpp.

pluginCreated

void KTextEditor::Application::pluginCreated ( const QString & name, KTextEditor::Plugin * plugin )

signal

This signal is emitted when an Plugin was loaded.

Parameters

name	name of plugin
plugin	the new plugin

pluginDeleted

void KTextEditor::Application::pluginDeleted ( const QString & name, KTextEditor::Plugin * plugin )

signal

This signal is emitted when an Plugin got deleted.

Parameters

name	name of plugin
plugin	the deleted plugin

Warning

Do not access the data referenced by the pointer, it is already invalid. Use the pointer only to remove mappings in hash or maps

quit()

bool KTextEditor::Application::quit

(

)

Ask app to quit.

The app might interact with the user and decide that quitting is not possible and return false.

Returns

true if the app could quit
