## Detailed Description

KTextEditor Plugin interface.

Topics: - plugin_intro - plugin_config - plugin_sessions - plugin_arch

Introduction

The Plugin class provides methods to create loadable plugins for all KTextEditor implementations. A plugin can handle several documents and views. For every document the plugin should handle addDocument() is called and for every view addView().

Configuration Management

To do: write docu about config pages (new with kpluginmanager) To do: write docu about save/load settings (related to config page)

Session Management

As an extension a Plugin can implement the SessionConfigInterface. This interface provides functions to read and write session related settings. If you have session dependent data additionally derive your Plugin from this interface and implement the session related functions, for example:

     class MyPlugin : public KTextEditor.Plugin,
                      public KTextEditor.SessionConfigInterface
     {
       Q_OBJECT
       Q_INTERFACES(KTextEditor.SessionConfigInterface)

       // ...
       virtual void readSessionConfig (const KConfigGroup& config);
       virtual void writeSessionConfig (KConfigGroup& config);
     };

Plugin Architecture

After the plugin is loaded the editor implementation should call addDocument() and addView() for all documents and views the plugin should handle. If your plugin has a GUI it is common to add an extra class, like:

     class PluginView : public QObject, public KXMLGUIClient
     {
         Q_OBJECT
     public:
         // Constructor and other methods
         PluginView( KTextEditor.View* view )
           : QObject( view ), KXMLGUIClient( view ), m_view( view )
         { ... }
         // ...
     private:
         KTextEditor.View* m_view;
     };

Your KTextEditor.Plugin derived class then will create a new PluginView for every View, i.e. for every call of addView().

The method removeView() will be called whenever a View is removed/closed. If you have a PluginView for every view this is the place to remove it.

## Methods

| __init__ (self, QObject parent)
| addDocument (self, KTextEditor.Document document)
| addView (self, KTextEditor.View view)
| removeDocument (self, KTextEditor.Document document)
| removeView (self, KTextEditor.View view)

## Method Documentation

__init__ | ( | self, |
|  | QObject | parent
| ) |  |  |

Constructor.

Create a new plugin.

Parameters:

  | parent | parent object

addDocument | ( | self, |
|  | KTextEditor.Document | document
| ) |  |  |

Add a new document to the plugin. This method is called whenever the plugin should handle another document.

For every call of addDocument() will finally follow a call of removeDocument(), i.e. the number of calls are identic.

Parameters:

  | document | new document to handle

See also:
  removeDocument(), addView()

addView | ( | self, |
|  | KTextEditor.View | view
| ) |  |  |

This method is called whenever the plugin should add its GUI to view. The process for the Editor can be roughly described as follows: - add documents the plugin should handle via addDocument() - for every document doc call addView() for every view for doc.

For every call of addView() will finally follow a call of removeView(), i.e. the number of calls are identic.

Note:
  As addView() is called for every view in which the plugin's GUI should be visible you must not add the GUI by iterating over all Document.views() yourself neither use the signal Document.viewCreated().

Parameters:

  | view | view to hang the gui in

See also:
  removeView(), addDocument()

removeDocument | ( | self, |
|  | KTextEditor.Document | document
| ) |  |  |

Remove the document from the plugin. This method is called whenever the plugin should stop handling the document.

For every call of addDocument() will finally follow a call of removeDocument(), i.e. the number of calls are identic.

Parameters:

  | document | document to hang the gui out from

See also:
  addDocument(), removeView()

removeView | ( | self, |
|  | KTextEditor.View | view
| ) |  |  |

This method is called whenever the plugin should remove its GUI from view.

For every call of addView() will finally follow a call of removeView(), i.e. the number of calls are identic.

Parameters:

  | view | view to hang the gui out from

  addView(), removeDocument()
