Direct Known Subclasses:

TextStructureTool

public class XMLStructureTool
extends org.eclipse.gef.tools.SelectionTool

XMLStructureTool - tool to make whole nodes selection
Structure is defined by tree of nodes, so this tool can select nodes of xml document.

1. Supports structure selection - selection is composed of nodes.
2. Selections are performed by mouse and keyboard.
3. Editing is performed through menu and keyboard.
4. Suports clipboard, undo, redo

Key and mouse functionality control:

• up, down arrow - selects brother of selected node; if more nodes are selected, deselects all
• CTRL + wheel - selects parent/child of selected node; if more nodes are selected, deselects all
• click in special place - square, triangel selects element assigned to that place. So elements are bounded by visible border with square at corner.
• some mechanism - selects elements only of selected type

Constructor.

Method Detail

getFocusEditPart

protected org.eclipse.gef.GraphicalEditPart getFocusEditPart()

Returns:

the EditPart that has focus

handleKeyDown

protected boolean handleKeyDown(KeyEvent event)

Overrides:

handleKeyDown in class org.eclipse.gef.tools.SelectionTool

selectSiblingNode

protected void selectSiblingNode(int direction)

Selects previous or next sibling of selected node(if not exists such sibling, does nothing). If more nodes are selected, selects nothing.

handleKeyUp

protected boolean handleKeyUp(KeyEvent e)

Overrides:

handleKeyUp in class org.eclipse.gef.tools.SelectionTool

ScrollUp

protected void ScrollUp(org.eclipse.gef.EditPartViewer viewer)

Selects parent of selected node. If more nodes are selected, does * nothing.

ScrollDown

protected void ScrollDown(org.eclipse.gef.EditPartViewer viewer)

Selects first child of selected node(TODO Studva some alg to select not first child). If more nodes are selected, selects nothing.

mouseWheelScrolled

public void mouseWheelScrolled(Event event,
                               org.eclipse.gef.EditPartViewer viewer)

Delegates the scrolling to the DragTracker (if there is one). If not, invokes the super method.

Specified by:

mouseWheelScrolled in interface org.eclipse.gef.Tool

Overrides:

mouseWheelScrolled in class org.eclipse.gef.tools.SelectionTool

See Also:

Tool.mouseWheelScrolled(org.eclipse.swt.widgets.Event, org.eclipse.gef.EditPartViewer)

canScroll

protected boolean canScroll()

getXMLGraphicalViewer

protected IXMLGraphicalViewer getXMLGraphicalViewer()

getXMLAcces

protected XMLAccess getXMLAcces()

updateTargetUnderMouse

Overrides:

updateTargetUnderMouse in class org.eclipse.gef.tools.TargetingTool

handleButtonDown

protected boolean handleButtonDown(int button)

Process only left mouse clicks (as selection or anything).

Overrides:

handleButtonDown in class org.eclipse.gef.tools.SelectionTool
