public GraphViewer()

Method Detail

doSave

public void doSave(org.eclipse.core.runtime.IProgressMonitor monitor)

Description copied from interface: org.eclipse.ui.ISaveablePart

Saves the contents of this part.

If the save is successful, the part should fire a property changed event reflecting the new dirty state (PROP_DIRTY property).

If the save is cancelled through user action, or for any other reason, the part should invoke setCancelled on the IProgressMonitor to inform the caller.

This method is long-running; progress and cancellation are provided by the given progress monitor.

Specified by:

doSave in interface org.eclipse.ui.ISaveablePart

---

doSaveAs

public void doSaveAs()

Description copied from interface: org.eclipse.ui.ISaveablePart

Saves the contents of this part to another object.

Implementors are expected to open a "Save As" dialog where the user will be able to select a new name for the contents. After the selection is made, the contents should be saved to that new name. During this operation a IProgressMonitor should be used to indicate progress.

If the save is successful, the part fires a property changed event reflecting the new dirty state (PROP_DIRTY property).

Specified by:

doSaveAs in interface org.eclipse.ui.ISaveablePart

---

gotoMarker

public void gotoMarker(org.eclipse.core.resources.IMarker marker)

---

init

public void init(org.eclipse.ui.IEditorSite site,
                 org.eclipse.ui.IEditorInput input)
          throws org.eclipse.ui.PartInitException

Description copied from interface: org.eclipse.ui.IEditorPart

Initializes this editor with the given editor site and input.

This method is automatically called shortly after the part is instantiated. It marks the start of the part's lifecycle. The IWorkbenchPart.dispose 55 method will be called automically at the end of the lifecycle. Clients must not call this method.

Implementors of this method must examine the editor input object type to determine if it is understood. If not, the implementor must throw a PartInitException

Specified by:

init in interface org.eclipse.ui.IEditorPart

---

setInput

public void setInput(org.eclipse.ui.IEditorInput input)

Description copied from class: org.eclipse.ui.part.EditorPart

Sets the input to this editor.

---

isDirty

public boolean isDirty()

Description copied from interface: org.eclipse.ui.ISaveablePart

Returns whether the contents of this part have changed since the last save operation. If this value changes the part must fire a property listener event with PROP_DIRTY.

Specified by:

isDirty in interface org.eclipse.ui.ISaveablePart

---

isSaveAsAllowed

public boolean isSaveAsAllowed()

Description copied from interface: org.eclipse.ui.ISaveablePart

Returns whether the "Save As" operation is supported by this part.

Specified by:

isSaveAsAllowed in interface org.eclipse.ui.ISaveablePart

---

createPartControl

public void createPartControl(org.eclipse.swt.widgets.Composite parent)

Description copied from interface: org.eclipse.ui.IWorkbenchPart

Creates the SWT controls for this workbench part.

Clients should not call this method (the workbench calls this method when it needs to, which may be never).

For implementors this is a multi-step process:

1. Create one or more controls within the parent.
2. Set the parent layout as needed.
3. Register any global actions with the IActionService.
4. Register any popup menus with the IActionService.
5. Register a selection provider with the ISelectionService (optional).

Specified by:

createPartControl in interface org.eclipse.ui.IWorkbenchPart

---

setFocus

public void setFocus()

Description copied from interface: org.eclipse.ui.IWorkbenchPart

Asks this part to take focus within the workbench.

Clients should not call this method (the workbench calls this method at appropriate times). To have the workbench activate a part, use IWorkbenchPage.activate(IWorkbenchPart) instead.

Specified by:

setFocus in interface org.eclipse.ui.IWorkbenchPart

---

isSaveOnCloseNeeded

public boolean isSaveOnCloseNeeded()

Description copied from interface: org.eclipse.ui.ISaveablePart

Returns whether the contents of this part should be saved when the part is closed.

Specified by:

isSaveOnCloseNeeded in interface org.eclipse.ui.ISaveablePart

---
