DrillDownAdapter

public class DrillDownAdapter implements ISelectionChangedListener(Code)

Implements a simple web style navigation metaphor for a TreeViewer. Home, back, and "drill into" functions are supported for the viewer,

To use the DrillDownAdapter ..

Create an instance of TreeViewer.
Create a DrillDownAdapter for the viewer.
Create a container for your viewer with a toolbar or a popup menu. Add actions for "goBack", "goHome", and "goInto" to either one by calling addNavigationActions with the popup menu or toolbar.

If the input for the underlying viewer is changed by something other than the adapter the reset method should be called. This will clear the drill stack and update the navigation buttons to reflect the new state of the underlying viewer.

Constructor Summary
public	DrillDownAdapter(TreeViewer tree) Allocates a new DrillDownTreePart.

Method Summary
public void	addNavigationActions(IMenuManager manager) Adds actions for "go back", "go home", and "go into" to a menu manager.
public void	addNavigationActions(IToolBarManager toolBar) Adds actions for "go back", "go home", and "go into" to a tool bar manager.
public boolean	canExpand(Object element) Returns whether expansion is possible for the current selection.
public boolean	canGoBack() Returns whether "go back" is possible for child tree.
public boolean	canGoHome() Returns whether "go home" is possible for child tree.
public boolean	canGoInto() Returns whether "go into" is possible for child tree.
public void	goBack() Reverts the input for the tree back to the state when `goInto` was last called. A frame is removed from the drill stack.
public void	goHome() Reverts the input for the tree back to the state when the adapter was created. All of the frames are removed from the drill stack.
public void	goInto() Sets the input for the tree to the current selection. The current input and expansion state are saved in a frame and added to the drill stack.
public void	goInto(Object newInput) Sets the input for the tree to a particular item in the tree. The current input and expansion state are saved in a frame and added to the drill stack.
public void	reset() Resets the drill down adapter.
public void	selectionChanged(SelectionChangedEvent event) Updates the navigation buttons when a selection change occurs in the tree.
protected void	updateNavigationButtons() Updates the enabled state for each navigation button.

Constructor Detail

DrillDownAdapter
public DrillDownAdapter(TreeViewer tree)(Code)
	Allocates a new DrillDownTreePart. Parameters: tree - the target tree for refocusing

Method Detail

addNavigationActions
public void addNavigationActions(IMenuManager manager)(Code)
	Adds actions for "go back", "go home", and "go into" to a menu manager. Parameters: manager - is the target manager to update

addNavigationActions
public void addNavigationActions(IToolBarManager toolBar)(Code)
	Adds actions for "go back", "go home", and "go into" to a tool bar manager. Parameters: toolBar - is the target manager to update

canExpand
public boolean canExpand(Object element)(Code)
	Returns whether expansion is possible for the current selection. This will only be true if it has children. Parameters: element - the object to test for expansion `true` if expansion is possible; otherwise return `false`

canGoBack
public boolean canGoBack()(Code)
	Returns whether "go back" is possible for child tree. This is only possible if the client has performed one or more drilling operations. `true` if "go back" is possible; `false` otherwise

canGoHome
public boolean canGoHome()(Code)
	Returns whether "go home" is possible for child tree. This is only possible if the client has performed one or more drilling operations. `true` if "go home" is possible; `false` otherwise

canGoInto
public boolean canGoInto()(Code)
	Returns whether "go into" is possible for child tree. This is only possible if the current selection in the client has one item and it has children. `true` if "go into" is possible; `false` otherwise

goBack
public void goBack()(Code)
	Reverts the input for the tree back to the state when `goInto` was last called. A frame is removed from the drill stack. Then that frame is used to reset the input and expansion state for the child tree.

goHome
public void goHome()(Code)
	Reverts the input for the tree back to the state when the adapter was created. All of the frames are removed from the drill stack. Then the oldest frame is used to reset the input and expansion state for the child tree.

goInto

public void goInto()(Code)

Sets the input for the tree to the current selection.

The current input and expansion state are saved in a frame and added to the drill stack. Then the input for the tree is changed to be the current selection. The expansion state for the tree is maintained during the operation.

On return the client may revert back to the previous state by invoking goBack or goHome.

goInto

public void goInto(Object newInput)(Code)

Sets the input for the tree to a particular item in the tree.

The current input and expansion state are saved in a frame and added to the drill stack. Then the input for the tree is changed to be newInput. The expansion state for the tree is maintained during the operation.

On return the client may revert back to the previous state by invoking goBack or goHome.

Parameters:
newInput - the new input element

reset
public void reset()(Code)
	Resets the drill down adapter. This method is typically called when the input for the underlying view is reset by something other than the adapter. On return the drill stack has been cleared and the navigation buttons reflect the new state of the underlying viewer.

selectionChanged
public void selectionChanged(SelectionChangedEvent event)(Code)
	Updates the navigation buttons when a selection change occurs in the tree.

updateNavigationButtons
protected void updateNavigationButtons()(Code)
	Updates the enabled state for each navigation button.
