  org.eclipse.gef.ui.parts.AbstractEditPartViewer
      org.eclipse.gef.ui.parts.GraphicalViewerImpl
          org.eclipse.gef.ui.parts.ScrollingGraphicalViewer
              sk.uniba.euromath.editor.textEditor.viewers.ScrollingTextGraphicalViewer

All Implemented Interfaces:

org.eclipse.gef.EditPartViewer, org.eclipse.gef.GraphicalViewer, ISelectionProvider, IDOMSelectionChangedListener, IDOMSelectionProvider, IXMLGraphicalViewer

public class ScrollingTextGraphicalViewer
extends org.eclipse.gef.ui.parts.ScrollingGraphicalViewer
implements IXMLGraphicalViewer

Overrides selection funcionality of ScrollingGraphicalViewer. Selection is represented by DOMIntervalSet. Converts DOMIntervals from DOMIntervalSet to EditParts and start offset and end offset in this EditParts Call @see #commitSelection() when selecting ends (mouse up, button up), this fires selection to selectionChangedListeners

Constructor Detail

ScrollingTextGraphicalViewer

public ScrollingTextGraphicalViewer(XMLEditor editor)

Parameters:

editor - Editor that uses this viewer to view its state

Method Detail

addSelectionChangedListener

public void addSelectionChangedListener(IDOMSelectionChangedListener listener)

Description copied from interface: IDOMSelectionProvider

Adds a listener for selection changes in this selection provider. Has no effect if an identical listener is already registered.

Specified by:

addSelectionChangedListener in interface IDOMSelectionProvider

Parameters:

listener - new listener to be add from selectionChangedListeners

removeSelectionChangedListener

public void removeSelectionChangedListener(IDOMSelectionChangedListener listener)

Description copied from interface: IDOMSelectionProvider

Removes the given selection change listener from this selection provider. Has no affect if an identical listener is not registered.

Specified by:

removeSelectionChangedListener in interface IDOMSelectionProvider

Parameters:

listener - listener to be removed from selectionChangedListeners

showSelection

public void showSelection(sk.baka.ikslibs.interval.DOMIntervalSet selection)

Description copied from interface: IXMLGraphicalViewer

Shows selection, but actual selection doesn't changes.

Specified by:

showSelection in interface IXMLGraphicalViewer

Parameters:

selection - the selection to show

setSelection

public void setSelection(sk.baka.ikslibs.interval.DOMIntervalSet selection)

Deselects editparts with Ids, that were in previous selection and select editparts that are in DOMIntervalSet

Specified by:

setSelection in interface IDOMSelectionProvider

Parameters:

selection - DOMIntervalSet containing DOMInetervals, that have to be selected

selectionChanged

public void selectionChanged(DOMSelectionChangedEvent event)

Effect is same as using setSelection

Specified by:

selectionChanged in interface IDOMSelectionChangedListener

Parameters:

event - DOMSelectionChangedEvent that contains source of new selction, that should be some XMLEditor and DOMIntervalSet as selection

fireSelectionChanged

protected void fireSelectionChanged()

This is called when selecting ends (mouse up or button up)

Overrides:

fireSelectionChanged in class org.eclipse.gef.ui.parts.AbstractEditPartViewer

select

protected void select(ITextPieceKeeper keeper,
                      int start,
                      int end)

select

public void select(org.eclipse.gef.EditPart editpart)

Selecting whole EditPart. When this EditPart was not in selected EditParts, than fireSelectionChanged() If editpart is ITextPieceKeeper then visualization is left on

Specified by:

select in interface org.eclipse.gef.EditPartViewer

Overrides:

select in class org.eclipse.gef.ui.parts.AbstractEditPartViewer

Parameters:

editpart - EditPart that is going to be selected

See Also:

If editpart is not ITextPieceKeeper then visualization is left on this editpart., EditPart#setSelected(EditPart.SELECTED)

deselect

public void deselect(org.eclipse.gef.EditPart editpart)

Deselecting whole EditPart. Alwas fires selection change If editpart is ITextPieceKeeper then visualization is left on

Specified by:

deselect in interface org.eclipse.gef.EditPartViewer

Overrides:

deselect in class org.eclipse.gef.ui.parts.AbstractEditPartViewer

Parameters:

editpart - EditPart that is going to be deselected

See Also:

If editpart is not ITextPieceKeeper then visualization is left on this editpart., EditPart#setSelected(EditPart.SELECTED_NONE)

deselectAll

public void deselectAll()

Deselects all selected editparts. At the end fires selection change

Specified by:

deselectAll in interface org.eclipse.gef.EditPartViewer

Overrides:

deselectAll in class org.eclipse.gef.ui.parts.AbstractEditPartViewer

commitSelection

public void commitSelection()

This tells to DOMSelectionChangeListeners(probably only TextEditor), about new selection. Local selection of this GraphiclViewer becomes a globalSelction Call this method when selction ends - mouse up, Shift key up, etc.

getSelectedEditParts

public List getSelectedEditParts()

Specified by:

getSelectedEditParts in interface org.eclipse.gef.EditPartViewer

Overrides:
