public class TextViewerOperationAction
extends TextViewerAction

An action which gets a text operation target from its text editor.

The action is initially associated with a text editor via the constructor, but can subsequently be changed using setEditor.

If this class is used as is, it works by asking the text editor for its text operation target adapter (using getAdapter(ITextOperationTarget.class). The action runs this operation with the pre-configured opcode.

Since:

2.3

Constructor Detail

TextViewerOperationAction

public TextViewerOperationAction(java.util.ResourceBundle bundle,
                         java.lang.String prefix,
                         org.eclipse.jface.text.ITextViewer viewer,
                         int operationCode)

Creates and initializes the action for the given text editor and operation code. The action configures its visual representation from the given resource bundle. The action works by asking the text editor at the time for its text operation target adapter (using getAdapter(ITextOperationTarget.class). The action runs that operation with the given opcode.

Parameters:

bundle - the resource bundle

prefix - a prefix to be prepended to the various resource keys (described in ResourceAction constructor), or null if none

viewer - the text viewer

operationCode - the operation code
