Method Detail

calculateCursor

protected Cursor calculateCursor()

Description copied from class: AbstractTool

Determines (and returns) the appropriate cursur.

Overrides:

calculateCursor in class AbstractTool

getCommandName

protected String getCommandName()

Description copied from class: AbstractTool

Returns the name identifier of the command that the tool is currently looking for.

Overrides:

getCommandName in class AbstractTool

getDebugName

protected String getDebugName()

Description copied from class: AbstractTool

Returns the debug name for this tool.

Overrides:

getDebugName in class AbstractTool

getSourceEditPart

protected EditPart getSourceEditPart()

handleButtonDown

protected boolean handleButtonDown(int button)

Description copied from class: AbstractTool

Called when the mouse button has been pressed. Should be implemented to process the users input correctly. Boolean should be used to indicate to your subclasses if you processed the event (true) or you didn't process it (false) and the subclass might process it. Key presses are a good example of this type of behavior.

Overrides:

handleButtonDown in class AbstractTool

handleButtonUp

protected boolean handleButtonUp(int button)

Description copied from class: AbstractTool

Handles the high-level processing of a mouse release.

Overrides:

handleButtonUp in class AbstractTool

Following copied from class: org.eclipse.gef.tools.AbstractTool

See Also:

AbstractTool.mouseUp(MouseEvent, EditPartViewer)

handleDoubleClick

protected boolean handleDoubleClick(int button)

Description copied from class: AbstractTool

Handles high-level processing of a double click.

Overrides:

handleDoubleClick in class AbstractTool

Following copied from class: org.eclipse.gef.tools.AbstractTool

See Also:

AbstractTool.mouseDoubleClick(MouseEvent, EditPartViewer)

handleDragStarted

protected boolean handleDragStarted()

Description copied from class: AbstractTool

Called once when the drag threshold has been passed.

Overrides:

handleDragStarted in class AbstractTool

Following copied from class: org.eclipse.gef.tools.AbstractTool

See Also:

AbstractTool.movedPastThreshold(), AbstractTool.mouseDrag(MouseEvent, EditPartViewer)

hasSelectionOccurred

protected boolean hasSelectionOccurred()

performConditionalSelection

protected void performConditionalSelection()

Ensures that the source EditPart is selected. If the source part is not selected, performSelection() is called. Note that either Control or Shift modifiers will still result in the source getting selected.

performSelection

protected void performSelection()

resetFlags

protected void resetFlags()

Description copied from class: AbstractTool

Resets the flags.

Overrides:

resetFlags in class AbstractTool

setSourceEditPart

protected void setSourceEditPart(EditPart part)
