Introduction
The EditorChooser is responsible for two different tasks: It provides - a GUI, with which the user can choose the preferred editor part - a static accessor, with which the current selected editor part can be obtained.
The GUI Editor Chooser The EditorChooser is a simple widget with a group box containing an information label and a combo box which lists all available KTextEditor implementations. To give the user the possibility to choose a text editor implementation, create an instance of this class and put it into the GUI:
KTextEditor.EditorChooser* ec = new KTextEditor.EditorChooser(parent); // read the settings from the application's KConfig object ec->readAppSetting(); // optionally connect the signal changed() // plug the widget into a layout layout->addWidget(ec);Later, for example when the user clicks the Apply-button:
// save the user's choice ec->writeAppSetting();After this, the static accessor editor() will return the new editor part object. Now, either the application has to be restarted, or you need code that closes all current documents so that you can safely switch and use the new editor part. Restarting is probably much easier.
- Note:
- If you do not put the EditorChooser into the GUI, the default editor component will be used. The default editor is configurable in KDE's control center in "KDE Components > Component Chooser > Embedded Text Editor".
Accessing the Editor Part The call of editor() will return the currently used editor part, either the KDE default or the one configured with the EditorChooser's GUI (see chooser_gui). Example:
KTextEditor.Editor* editor = KTextEditor.EditorChooser.editor();

Signal Documentation
changed | ( | ) |
This signal is emitted whenever the selected item in the combo box changed.
- Signal syntax:
QObject.connect(source, SIGNAL("changed()"), target_slot)
Method Documentation
__init__ | ( | self, | ||
QWidget | parent=0 | |||
) |
Constructor.
Create an editor chooser widget.
- Parameters:
-
parent the parent widget
readAppSetting | ( | self, | ||
QString | postfix=QString() | |||
) |
Read the configuration from the application's config file. The group is handeled internally (it is called "KTEXTEDITOR:", but it is possible to add a string to extend the group name with postfix.
- Parameters:
-
postfix config group postfix string
- See also:
- writeAppSetting()
writeAppSetting | ( | self, | ||
QString | postfix=QString() | |||
) |
Write the configuration to the application's config file.
- Parameters:
-
postfix config group postfix string
- See also:
- readAppSetting()
Static Method Documentation
KTextEditor.Editor editor | ( | QString | postfix=QString(), | |
bool | fallBackToKatePart=1 | |||
) |
Static accessor to get the Editor instance of the currently used KTextEditor component.
That Editor instance can be qobject-cast to specific extensions. If the result of the cast is not NULL, that extension is supported:
- Parameters:
-
postfix config group postfix string
- Parameters:
-
fallBackToKatePart if true, the returned Editor component will be a katepart if no other implementation can be found
- Returns:
- Editor controller or NULL, if no editor component could be found
