The RotatingTool is used to interactively change the GraphObject#angle of a GraphObject. This tool allows the user to rotate the Part#rotateObject of the selected Part. Normally this works with Parts or Nodes; it does not make sense for Links. The Part must be Part#rotatable, which is false by default.
You do not normally need to create an instance of this tool because one already exists as the ToolManager#rotatingTool, which you can modify.
Gets the GraphObject that is being rotated.
Gets the Diagram that owns this tool and for which this tool is handling input events.
Gets or sets a small GraphObject that is copied as a rotation handle for the selected part.
Gets or sets a small GraphObject that is copied as a rotation handle for the selected part.
Gets or sets whether this tool is started and is actively doing something.
Gets or sets whether this tool can be started by a mouse event.
Gets or sets the name of this tool.
Gets the angle that was the original value of the GraphObject#angle of the GraphObject that is being rotated.
Gets or sets the the closeness to a desired angle at which the angle is "snapped to".
Gets or sets the preferred angles for the selected object.
Gets or sets the name of the transaction to be committed by #stopTransaction; if null, the transaction will be rolled back.
This tool may run when there is a mouse-down event on a rotate handle, the diagram is not read-only and it allows rotation, the left mouse button is being used, and this tool's adornment's rotate handle is at the current mouse point.
boolean
This is called to cancel any running "WaitAfter" timer.
any
Compute the new angle given a point.
number
Capture the mouse, remember the original GraphObject#angle, and start a transaction.
any
Restore the original GraphObject#angle of the adorned object.
any
Stop the current transaction and release the mouse.
any
The diagram will call this method upon a key down event.
any
The diagram will call this method upon a key up event.
any
The diagram will call this method upon a mouse down event.
any
Call #rotate with a new angle determined by the current mouse point.
any
Call #rotate with an angle based on the most recent mouse point, commit the transaction, and raise the "PartRotated" DiagramEvent.
any
The diagram will call this method as the mouse wheel is rotated.
any
This method is called by the diagram when this tool becomes the current tool; you should not call this method.
any
This method is called by the diagram when this tool stops being the current tool; you should not call this method.
any
This is called a certain delay after a call to #standardWaitAfter if there has not been any call to #cancelWaitAfter.
any
This convenience function finds the front-most GraphObject that is at a given point and that is part of an Adornment that is of a given category.
a Point in document coordinates.
the required Part#category of the Adornment.
Return true when the last mouse point is far enough away from the first mouse down point to constitute a drag operation instead of just a potential click.
Point in view coordinates, defaults to Diagram#firstInput's InputEvent#viewPoint.
Point in view coordinates, defaults to Diagram#lastInput's InputEvent#viewPoint.
boolean
Change the angle of the selected part's Part#rotateObject.
any
Implement the standard behavior for mouse clicks, searching for and calling click handler functions on GraphObjects or on Diagram, and raising the corresponding DiagramEvent.
An optional custom navigation function to find target objects.
An optional custom predicate
any
Implement the standard behavior for mouse enter, over, and leave events, where the mouse is moving but no button is pressed.
any
Implement the standard behavior for selecting parts with the mouse, depending on the control and shift modifier keys.
any
Implement the standard behavior for mouse wheel events.
any
This is called to start a new timer to call #doWaitAfter after a given delay.
in milliseconds
any
Call Diagram#startTransaction with the given transaction name.
a description of the transaction
boolean
If the Diagram#currentTool is this tool, stop this tool and start the Diagram#defaultTool by making it be the new current tool.
any
If #transactionResult is null, call Diagram#rollbackTransaction, otherwise call Diagram#commitTransaction.
boolean
Show an Adornment with a rotate handle at a point to the side of the adorned object if the part is selected and visible and if Part#canRotate() is true.
any
