Detailed Description

Accessor interface for Editor part.

Topics:

  • Introduction
  • Editor Configuration
  • Implementation Notes
  • Editor Extension Interfaces

Introduction

The Editor part can be accessed via the KTextEditor::Factory or the KTextEditor::EditorChooser and provides general information and configuration methods for the Editor implementation, for example KAboutData by using aboutData().

The Editor implementation has a list of all opened documents. Get this list with documents(). To create a new Document call createDocument(). The signal documentCreated() is emitted whenever the Editor created a new document.

Editor Configuration

If the Editor implementation supports a config dialog configDialogSupported() returns true, then the config dialog can be shown with configDialog(). Instead of using the config dialog, the config pages can be embedded into the application's config dialog. To do this, configPages() returns the number of config pages the Editor implementation provides and configPage() returns the requested page. Further, a config page has a short descriptive name, get it with configPageName(). You can get more detailed name by using configPageFullName(). Also every config page has a pixmap, get it with configPagePixmap(). The configuration can be saved and loaded with readConfig() and writeConfig().

Note:
We recommend to embedd the config pages into the main application's config dialog instead of using a separate config dialog, if the config dialog does not look cluttered then. This way, all settings are grouped together in one place.

Implementation Notes

Usually only one instance of the Editor exists. The Kate Part implementation internally uses a static accessor to make sure that only one Kate Part Editor object exists. So several factories still use the same Editor.

readConfig() and writeConfig() should be forwarded to all loaded plugins as well, see KTextEditor::Plugin::readConfig() and KTextEditor::Plugin::writeConfig().

Editor Extension Interfaces

There is only a single extension interface for the Editor: the CommandInterface. With the CommandInterface it is possible to add and remove new command line commands which are valid for all documents. Common use cases are for example commands like find or setting document variables. For further details read the detailed descriptions in the class KTextEditor::CommandInterface.

Constructor & Destructor Documentation

Editor::Editor ( QObject *  parent  ) 

Constructor.

Create the Editor object with parent.

Parameters:
parent parent object

Definition at line 86 of file ktexteditor.cpp.

Editor::~Editor (  )  [virtual]

Virtual destructor.

Definition at line 92 of file ktexteditor.cpp.


Member Function Documentation

virtual const KAboutData* KTextEditor::Editor::aboutData (  )  const [pure virtual]

Get the about data of this Editor part.

Returns:
about data

virtual void KTextEditor::Editor::configDialog ( QWidget *  parent  )  [pure virtual]

Show the editor's config dialog, changes will be applied to the editor, but not saved anywhere automagically, call writeConfig() to save them.

Note:
Instead of using the config dialog, the config pages can be embedded into your own config dialog by using configPages() and configPage().
Parameters:
parent parent widget
See also:
configDialogSupported()

virtual bool KTextEditor::Editor::configDialogSupported (  )  const [pure virtual]

Check, whether this editor has a configuration dialog.

Returns:
true, if the editor has a configuration dialog, otherwise false
See also:
configDialog()

virtual ConfigPage* KTextEditor::Editor::configPage ( int  number,
QWidget *  parent 
) [pure virtual]

Get the config page with the number, config pages from 0 to configPages()-1 are available if configPages() > 0.

Parameters:
number index of config page
parent parent widget for config page
Returns:
created config page or NULL, if the number is out of bounds
See also:
configPages()

virtual QString KTextEditor::Editor::configPageFullName ( int  number  )  const [pure virtual]

Get a readable full name for the config page number.

The name should be translated.

Example: If the name is "Filetypes", the full name could be "Filetype Specific Settings". For "Shortcuts" the full name would be something like "Shortcut Configuration".

Parameters:
number index of config page
Returns:
full name of given page index
See also:
configPageName(), configPagePixmap()

virtual KIcon KTextEditor::Editor::configPageIcon ( int  number  )  const [pure virtual]

Get a pixmap with size for the config page number.

Parameters:
number index of config page
Returns:
pixmap for the given page index
See also:
configPageName(), configPageFullName()

virtual QString KTextEditor::Editor::configPageName ( int  number  )  const [pure virtual]

Get a readable name for the config page number.

The name should be translated.

Parameters:
number index of config page
Returns:
name of given page index
See also:
configPageFullName(), configPagePixmap()

virtual int KTextEditor::Editor::configPages (  )  const [pure virtual]

Get the number of available config pages.

If the editor returns a number < 1, it does not support config pages and the embedding application should use configDialog() instead.

Returns:
number of config pages
See also:
configPage(), configDialog()

virtual Document* KTextEditor::Editor::createDocument ( QObject *  parent  )  [pure virtual]

Create a new document object with parent.

Parameters:
parent parent object
Returns:
new KTextEditor::Document object
See also:
documents()

void KTextEditor::Editor::documentCreated ( KTextEditor::Editor *  editor,
KTextEditor::Document *  document 
) [signal]

The editor emits this signal whenever a document was successfully created.

Parameters:
editor editor which created the new document
document the newly created document instance
See also:
createDocument()

virtual const QList<Document*>& KTextEditor::Editor::documents (  )  [pure virtual]

Get a list of all documents of this editor.

Returns:
list of all existing documents
See also:
createDocument()

virtual void KTextEditor::Editor::readConfig ( KConfig *  config = 0  )  [pure virtual]

Read editor configuration from KConfig config.

Note:
Implementation Notes: If config is NULL you should use kapp->config() as a fallback solution. Additionally the readConfig() call should be forwarded to every loaded plugin.
Parameters:
config config object
See also:
writeConfig()

void Editor::setSimpleMode ( bool  on  ) 

Switch editor to simple mode for average users.

Switch the editor to a simple mode which will hide advanced stuff from average user or switch it back to normal mode. This mode will only affect documents/views created after the change.

Parameters:
on turn simple mode on or not

Definition at line 97 of file ktexteditor.cpp.

bool Editor::simpleMode (  )  const

Query the editor whether simple mode is on or not.

Returns:
true if simple mode is on, otherwise false
See also:
setSimpleMode()

Definition at line 102 of file ktexteditor.cpp.

virtual void KTextEditor::Editor::writeConfig ( KConfig *  config = 0  )  [pure virtual]

Write editor configuration to KConfig config.

Note:
Implementation Notes: If config is NULL you should use kapp->config() as a fallback solution. Additionally the writeConfig() call should be forwarded to every loaded plugin.
Parameters:
config config object
See also:
readConfig()
