Java Source Code / Java Documentation » IDE Eclipse » ui workbench » org.eclipse.ui.internal   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.eclipse.ui.internal.PerspectiveHelper PerspectiveHelper public class PerspectiveHelper (Code) A perspective presentation is a collection of parts with a layout. Each part is parented to a main window, so you can create more than one presentation on a set of parts and change the layout just by activating / deactivating a presentation. In addition, the user can change the position of any part by mouse manipulation (drag & drop). If a part is removed, we leave a placeholder behind to indicate where it goes should the part be added back.

Field Detail dropTarget protected ActualDropTarget dropTarget(Code) Constructor Detail PerspectiveHelper public PerspectiveHelper(WorkbenchPage workbenchPage, ViewSashContainer mainLayout, Perspective perspective)(Code) Constructs a new object. Method Detail activate public void activate(Composite parent)(Code) Show the presentation. addDetachedPart public void addDetachedPart(LayoutPart part)(Code) Create a detached window containing a part. addDetachedPart public void addDetachedPart(LayoutPart part, Rectangle bounds)(Code) addPart public void addPart(LayoutPart part)(Code) Adds a part to the presentation. If a placeholder exists for the part then swap the part in. Otherwise, add the part in the bottom right corner of the presentation. attachPart public void attachPart(IViewReference ref)(Code) Attaches a part that was previously detached to the mainLayout. Parameters:   ref - bringPartToTop public boolean bringPartToTop(LayoutPart part)(Code) Bring a part forward so it is visible. true if the part was brought to top, false if not. canDetach public boolean canDetach()(Code) Return whether detachable parts can be supported. collectViewPanes public void collectViewPanes(List result)(Code) Answer a list of the view panes. deactivate public void deactivate()(Code) Hide the presentation. derefPart void derefPart(LayoutPart part)(Code) Deref a given part. Deconstruct its container as required. Do not remove drag listeners. describeLayout public void describeLayout(StringBuffer buf)(Code) Writes a description of the layout to the given string buffer. This is used for drag-drop test suites to determine if two layouts are the same. Like a hash code, the description should compare as equal iff the layouts are the same. However, it should be user-readable in order to help debug failed tests. Although these are english readable strings, they should not be translated or equality tests will fail. This is only intended for use by test suites. Parameters:   buf - detachPart public void detachPart(IViewReference ref)(Code) Detached a part from the mainLayout. Presently this does not use placeholders since the current implementation is not robust enough to remember a view's position in more than one root container. For now the view is simply derefed and will dock in the default position when attachPart is called. By default parts detached this way are set to float on top of the workbench without docking. It is assumed that people that want to drag a part back onto the WorkbenchWindow will detach it via drag and drop. Parameters:   ref - dispose public void dispose()(Code) findPart public LayoutPart findPart(String primaryId, String secondaryId)(Code) Find the first part that matches the specified primary and secondary id pair. Wild cards are supported. forceNoZoom public void forceNoZoom()(Code) Forces the perspective to have no zoomed or minimized parts. This is used when switching to the 3.3 presentation... getCachedBoundsFor public Rectangle getCachedBoundsFor(String id)(Code) getDockingRatio public static float getDockingRatio(LayoutPart source, LayoutPart target)(Code) Returns the ratio that should be used when docking the given source part onto the given target Parameters:   source - newly added part Parameters:   target - existing part being dragged over the final size of the source part (wrt the current size of target)after it is docked getLayout public ViewSashContainer getLayout()(Code) Returns the layout container. getMaximizedStack public PartStack getMaximizedStack()(Code) The currently maxmized stack (if any) hasPlaceholder public boolean hasPlaceholder(String id)(Code) Returns true if a placeholder exists for a given ID. hasPlaceholder public boolean hasPlaceholder(String primaryId, String secondaryId)(Code) Returns true if a placeholder exists for a given ID. since:    3.0 isActive public boolean isActive()(Code) Gets the active state. isPartVisible public boolean isPartVisible(IWorkbenchPartReference partRef)(Code) Returns true if the given part is visible. A part is visible if it's top-level (not in a tab folder) or if it is the top one in a tab folder. isZoomed public boolean isZoomed()(Code) Returns whether the presentation is zoomed. NOTE: As of 3.3 this method should always return 'false' when using the new min/max behavior. It is only used for legacy 'zoom' handling. partChangeAffectsZoom public boolean partChangeAffectsZoom(LayoutPart pane)(Code) Returns whether changes to a part will affect zoom. There are a few conditions for this .. - we are zoomed. - the part is contained in the main window. - the part is not the zoom part - the part is not a fast view - the part and the zoom part are not in the same editor workbook - the part and the zoom part are not in the same view stack. removePart public void removePart(LayoutPart part)(Code) Remove all references to a part. replacePlaceholderWithPart public void replacePlaceholderWithPart(LayoutPart part)(Code) Add a part to the presentation. Note: unlike all other LayoutParts, PartPlaceholders will still point to their parent container even when it is inactive. This method relies on this fact to locate the parent. resetBoundsMap public void resetBoundsMap()(Code) Resets the bounds map so that it won't interfere with normal minimize operayions restoreState public IStatus restoreState(IMemento memento)(Code) See Also:   org.eclipse.ui.IPersistable saveState public IStatus saveState(IMemento memento)(Code) See Also:   org.eclipse.ui.IPersistable setMaximizedStack public void setMaximizedStack(PartStack stack)(Code) Sets the currently maximized stack. Used for query and 'unZoom' purposes in the 3.3 presentation. Parameters:   stack - The newly maximized stack updateBoundsMap public void updateBoundsMap()(Code) Captures the current bounds of all ViewStacks and the editor area and puts them into an ID -> Rectangle map. This info is used to cache the bounds so that we can correctly place minimized stacks during a 'maximized' operation (where the iterative min's affect the current layout while being performed. willPartBeVisible public boolean willPartBeVisible(String partId)(Code) Returns true is not in a tab folder or if it is the top one in a tab folder. willPartBeVisible public boolean willPartBeVisible(String partId, String secondaryId)(Code) zoomIn public void zoomIn(IWorkbenchPartReference ref)(Code) Zoom in on a particular layout part. zoomOut public void zoomOut()(Code) Zoom out.
