Public Methods
| Name | Description | |
|---|---|---|
 | CanStart | Overridden. Allow this tool to start if the user isn't using the context button and if the mouse isn't over an object in the document. |
| ComputeRubberBandBox | Overridden. Make the box keep the aspect ratio of the observed view. |
| DoCancelMouse | The view calls this method when the user cancels the gesture with the mouse; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoClick | Any tool can call this method in order to implement the standard click behavior. (Inherited from Northwoods.Go.GoTool) |
| DoKeyDown | The view calls this method when the user presses a key on the keyboard; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoMouseDown | This starts keeping track of the Box's bounds. (Inherited from Northwoods.Go.GoToolRubberBanding) |
| DoMouseHover | The view calls this method after the mouse rests for a while at a point; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoMouseMove | As the mouse is dragged, we display the rubber band box. (Inherited from Northwoods.Go.GoToolRubberBanding) |
| DoMouseUp | When the mouse is released, we remove the rubber band box, call DoRubberBand, and stop this tool if Modal is false. (Inherited from Northwoods.Go.GoToolRubberBanding) |
| DoMouseWheel | The view calls this method as the mouse wheel rotates; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoRubberBand | Overridden. Instead of selecting objects within a rectangle, change the ZoomedView's GoView.DocPosition and GoView.DocScale to match the given box within this view. |
| DoSelect | Any tool can call this method in order to implement the standard selection behavior for a user click. (Inherited from Northwoods.Go.GoTool) |
| IsBeyondDragSize | Determine if the mouse has gone beyond the DragSize distance to be considered a drag instead of a sloppy click. (Inherited from Northwoods.Go.GoTool) |
| Start | This method is called when this tool becomes the view's current tool. (Inherited from Northwoods.Go.GoTool) |
| StartTransaction | Start a transaction on the view. (Inherited from Northwoods.Go.GoTool) |
| Stop | Remove the rubber band box from the view. (Inherited from Northwoods.Go.GoToolRubberBanding) |
| StopTool | This method just causes the view's current tool to be stopped and to start the view's default tool instead as the current tool. (Inherited from Northwoods.Go.GoTool) |
| StopTransaction | Stop the current transaction, aborting it if TransactionResult is null. (Inherited from Northwoods.Go.GoTool) |
