Field Detail

fEncodingSupport

protected 
DefaultEncodingSupport fEncodingSupport
The encoding support for the editor.

Since:
2.0
Constructor Detail

TextEditor

public TextEditor()
Creates a new text editor.

Method Detail

initializeEditor

protected void initializeEditor()
Initializes this editor. Subclasses may re-implement. If sub-classes do not change the contract, this method should not be extended, i.e. do not call super.initializeEditor() in order to avoid the temporary creation of objects that are immediately overwritten by subclasses. This method configures the editor but does not define a SourceViewerConfiguration. When only interested in providing a custom source viewer configuration, subclasses may extend this method.

Overrides:
initializeEditor in class AbstractDecoratedTextEditor

dispose

public void dispose()
Description copied from class: AbstractTextEditor
The AbstractTextEditor implementation of this IWorkbenchPart method may be extended by subclasses. Subclasses must call super.dispose().

Note that many methods may return null after the editor is disposed.

Specified by:
dispose in interface IWorkbenchPart
Overrides:
dispose in class AbstractDecoratedTextEditor

installEncodingSupport

protected void installEncodingSupport()
Installs the encoding support on the given text editor.

Subclasses may override to install their own encoding support or to disable the default encoding support.

Since:
2.1

isSaveAsAllowed

public boolean isSaveAsAllowed()
Description copied from class: AbstractTextEditor
The AbstractTextEditor implementation of this IEditorPart method returns false. Subclasses may override.

Specified by:
isSaveAsAllowed in interface ISaveablePart
Overrides:
isSaveAsAllowed in class AbstractTextEditor
Returns:
false

createActions

protected void createActions()
Description copied from class: AbstractTextEditor
Creates this editor's standard actions and connects them with the global workbench actions.

Subclasses may extend.

Overrides:
createActions in class AbstractDecoratedTextEditor

getStatusHeader

protected 
String getStatusHeader(
IStatus status)
Description copied from class: StatusTextEditor
Returns a header for the given status

Overrides:
getStatusHeader in class StatusTextEditor
Parameters:
status - the status whose message is returned
Returns:
a header for the given status

getStatusBanner

protected 
String getStatusBanner(
IStatus status)
Description copied from class: StatusTextEditor
Returns a banner for the given status.

Overrides:
getStatusBanner in class StatusTextEditor
Parameters:
status - the status whose message is returned
Returns:
a banner for the given status

getStatusMessage

protected 
String getStatusMessage(
IStatus status)
Description copied from class: StatusTextEditor
Returns a message for the given status.

Overrides:
getStatusMessage in class StatusTextEditor
Parameters:
status - the status whose message is returned
Returns:
a message for the given status

doSetInput

protected void doSetInput(
IEditorInput input)
                   throws 
CoreException
Description copied from class: AbstractTextEditor
Called directly from setInput and from within a workspace runnable from init, this method does the actual setting of the editor input. Closes the editor if input is null. Disconnects from any previous editor input and its document provider and connects to the new one.

Subclasses may extend.

Overrides:
doSetInput in class AbstractDecoratedTextEditor
Parameters:
input - the input to be set
Throws:
CoreException - if input cannot be connected to the document provider

getAdapter

public 
Object getAdapter(
Class adapter)
Description copied from class: WorkbenchPart
Returns an object which is an instance of the given class associated with this object. Returns null if no such object can be found. Subclasses may override this method (however, if they do so, they should invoke the method on their superclass to ensure that the Platform's adapter manager is consulted).

Specified by:
getAdapter in interface IAdaptable
Overrides:
getAdapter in class AbstractDecoratedTextEditor
Parameters:
adapter - the adapter class to look up
Returns:
a object castable to the given class, or null if this object does not have an adapter for the given class

updatePropertyDependentActions

protected void updatePropertyDependentActions()
Description copied from class: AbstractTextEditor
Updates all property dependent actions.

Overrides:
updatePropertyDependentActions in class AbstractTextEditor

handlePreferenceStoreChanged

protected void handlePreferenceStoreChanged(
PropertyChangeEvent event)
Description copied from class: AbstractTextEditor
Handles a property change event describing a change of the editor's preference store and updates the preference related editor properties.

Subclasses may extend.

Overrides:
handlePreferenceStoreChanged in class AbstractDecoratedTextEditor
Parameters:
event - the property change event

editorContextMenuAboutToShow

protected void editorContextMenuAboutToShow(
IMenuManager menu)
Description copied from class: AbstractTextEditor
Sets up this editor's context menu before it is made visible.

Subclasses may extend to add other actions.

Overrides:
editorContextMenuAboutToShow in class AbstractDecoratedTextEditor
Parameters:
menu - the menu
