Constructor Detail

TreeViewer

public TreeViewer()
Constructs a TreeViewer with the default root editpart.

Method Detail

createControl

public Control createControl(Composite parent)
Creates the default tree and sets it as the control. The default styles will show scrollbars as needed, and allows for multiple selection.

Specified by:
createControl in interface EditPartViewer
Specified by:
createControl in class AbstractEditPartViewer
Parameters:
parent - The parent for the Tree
Returns:
the control
See Also:
EditPartViewer.createControl(Composite)

findObjectAtExcluding

public 
EditPart findObjectAtExcluding(
Point pt,
                                      java.util.Collection exclude,
                                      
EditPartViewer.Conditional condition)
Description copied from interface: EditPartViewer
Returns null or the EditPart at the specified location, using the given exclusion set and conditional. This method behaves similarly to EditPartViewer.findObjectAt(Point).

Parameters:
pt - The mouse location
exclude - The set of EditParts to be excluded
condition - the Conditional used to evaluate a potential hit
Returns:
null or an EditPart
See Also:
EditPartViewer.findObjectAtExcluding(Point, Collection, EditPartViewer.Conditional)

fireSelectionChanged

protected void fireSelectionChanged()
Description copied from class: AbstractEditPartViewer
Fires selection changed to the registered listeners at the time called.

Overrides:
fireSelectionChanged in class AbstractEditPartViewer
See Also:
AbstractEditPartViewer.fireSelectionChanged()

hookControl

protected void hookControl()
"Hooks up" a Control, i.e. sets it as the control for the RootTreeEditPart, adds necessary listener for proper operation, etc.

Overrides:
hookControl in class AbstractEditPartViewer
See Also:
AbstractEditPartViewer.unhookControl()

reveal

public void reveal(
EditPart part)
Description copied from interface: EditPartViewer
Reveals the given EditPart if it is not visible.

Specified by:
reveal in interface EditPartViewer
Overrides:
reveal in class AbstractEditPartViewer
See Also:
AbstractEditPartViewer.reveal(org.eclipse.gef.EditPart)

unhookControl

protected void unhookControl()
Unhooks a control so that it can be reset. This method deactivates the contents, removes the Control as being the Control of the RootTreeEditPart, etc. It does not remove the listeners because it is causing errors, although that would be a desirable outcome.

Overrides:
unhookControl in class AbstractEditPartViewer
