Constructor Detail

SharedHeaderFormEditor

public SharedHeaderFormEditor()

The default constructor.

Method Detail

createPageContainer

protected Composite createPageContainer(Composite parent)

Overrides super to create a form in which to host the tab folder. This form will be responsible for creating a common form header. Child pages should not have a header of their own.

Overrides:

createPageContainer in class FormEditor

Parameters:

parent - the page container parent

Returns:

the parent for this editor's container. Must not be null.

See Also:

MultiPageEditorPart.createPageContainer(org.eclipse.swt.widgets.Composite)

getHeaderForm

public IManagedForm getHeaderForm()

Returns the form that owns the shared header.

Returns:

the shared header

createPages

protected void createPages()

Description copied from class: FormEditor

Creates the common toolkit for this editor and adds pages to the editor.

Overrides:

createPages in class FormEditor

See Also:

FormEditor.addPages()

setActivePage

protected void setActivePage(int pageIndex)

Description copied from class: MultiPageEditorPart

Sets the currently active page.

Overrides:

setActivePage in class FormEditor

Parameters:

pageIndex - the index of the page to be activated; the index must be valid

See Also:

MultiPageEditorPart.setActivePage(int)

setFocus

public void setFocus()

Description copied from class: MultiPageEditorPart

The MultiPageEditor implementation of this IWorkbenchPart method sets focus on the active nested editor, if there is one.

Subclasses may extend or reimplement.

Specified by:

setFocus in interface IWorkbenchPart

Overrides:

setFocus in class MultiPageEditorPart

dispose

public void dispose()

Description copied from class: FormEditor

Disposes the pages and the toolkit after disposing the editor itself. Subclasses must call 'super' when reimplementing the method.

Specified by:

dispose in interface IWorkbenchPart

Overrides:

dispose in class FormEditor

isDirty

public boolean isDirty()

Description copied from class: FormEditor

Tests whether the editor is dirty by checking all the pages that implement IFormPage. If none of them is dirty, the method delegates further processing to super.isDirty().

Specified by:

isDirty in interface ISaveablePart

Overrides:

isDirty in class FormEditor

Returns:

true if any of the pages in the editor are dirty, false otherwise.

commitPages

protected void commitPages(boolean onSave)

Description copied from class: FormEditor

Commits all dirty pages in the editor. This method should be called as a first step of a 'save' operation.

Overrides:

commitPages in class FormEditor

Parameters:

onSave - true if commit is performed as part of the 'save' operation, false otherwise.

createHeaderContents

protected void createHeaderContents(IManagedForm headerForm)

Subclasses should extend this method to configure the form that owns the shared header. If the header form will contain controls that can change the state of the editor, they should be wrapped in an IFormPart so that they can participate in the life cycle event management.

Parameters:

headerForm - the form that owns the shared header
