 CompareEditorInput editorInput)

Method Details

getViewer

protected Viewer getViewer(Viewer oldViewer,
 Object input)

Description copied from class: CompareViewerSwitchingPane

Returns a viewer which is able to display the given input. If no viewer can be found, null is returned. The additional argument oldViewer represents the viewer currently installed in the pane (or null if no viewer is installed). It can be returned from this method if the current viewer can deal with the input (and no new viewer must be created).

Specified by:

getViewer in class CompareViewerSwitchingPane

Parameters:

oldViewer - the currently installed viewer or null

input - the input object for which a viewer must be determined or null

Returns:

a viewer for the given input, or null if no viewer can be determined

createTopLeft

protected Control createTopLeft(Composite p)

Overrides:

createTopLeft in class CompareViewerPane

Parameters:

p - a widget which will be the parent of the control (cannot be null)

Returns:

the control to be placed in the top left corner of the pane

inputChanged

protected boolean inputChanged(Object input)

Overrides:

inputChanged in class CompareViewerSwitchingPane

Parameters:

input - the input

Returns:

true, if the input is considered as changed

setInput

public void setInput(Object input)

Description copied from class: CompareViewerSwitchingPane

Sets the input object of this pane. For this input object a suitable viewer is determined by calling the abstract method getViewer(Viewer, Object). If the returned viewer differs from the current one, the old viewer is disposed and the new one installed. Then the input object is fed into the newly installed viewer by calling its setInput(Object) method. If new and old viewer don't differ no new viewer is installed but just setInput(Object) is called. If the input is null the pane is cleared, that is the current viewer is disposed.

Overrides:

setInput in class CompareViewerSwitchingPane

Parameters:

input - the new input object or null

setText

public void setText(String text)

Description copied from class: CompareViewerPane

Set the pane's title text. The value null clears it.

Overrides:

setText in class CompareViewerPane

Parameters:

text - the text to be displayed in the pane or null

setImage

public void setImage(Image image)

Description copied from class: CompareViewerPane

Set the pane's title Image. The value null clears it.

Overrides:

setImage in class CompareViewerPane

Parameters:

image - the image to be displayed in the pane or null

addMouseListener

public void addMouseListener(MouseListener listener)

Description copied from class: Control

Adds the listener to the collection of listeners who will be notified when mouse buttons are pressed and released, by sending it one of the messages defined in the MouseListener interface.

Overrides:

addMouseListener in class Control

Parameters:

listener - the listener which should be notified
