Constructor Detail

ShiftAction

public ShiftAction(ResourceBundle bundle,
                   String prefix,
                   ITextEditor editor,
                   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

editor - the text editor

operationCode - the operation code

setEditor

public void setEditor(ITextEditor editor)

Description copied from class: TextEditorAction

Retargets this action to the given editor.

Overrides:

setEditor in class TextEditorAction

Parameters:

editor - the new editor, or null if none

isEnabled

public boolean isEnabled(boolean isWritable)

Description copied from interface: IReadOnlyDependent

Returns whether the actions would be enabled if its target would be enabled given the writable state described by isWritable. isEnabled() and isEnabled(boolean) holds the following invariants: isEnabled() == false, if isEnabled(true) == false || isEnabled(false) == false isEnabled() == true, if isEnabled(true) == true || isEnabled(false) == true

Specified by:

isEnabled in interface IReadOnlyDependent

Parameters:

isWritable -

Returns:

the hypothetical enable state of the action
