Class BaseTool

java.lang.Object
  extended by com.esri.arcgis.controls.BaseCommand
      extended by com.esri.arcgis.controls.BaseTool
All Implemented Interfaces:
ICommand, ITool, java.io.Serializable

public class BaseTool
extends BaseCommand
implements ITool

This is a helper class for creating custom tools. It implements the ITool interface and exteds the BaseCommand class. It forces the user to implement the OnCreate method. public class BaseTest extends BaseTool { public BaseTest() { bitmapPath = "icons/identify.bmp"; cursorPath = "icons/identify.cur"; caption = "Identify"; category = "Commands"; message = "Identifies the geographic features or place you click on"; name = "CustomCommands_Identify"; toolTip = "Identify"; enabled = true; } Then this Base test can be used as a tool and added to the ToolBarBean. Here toolbar is the ToolBarBean. toolbar.addItem(new BaseTest(),0,-1,false,0,esriCommandStyles.esriCommandStyleIconOnly);

Remarks

When implementing ITool to create a custom tool, write code to display a custom context menu when the right mouse button is pressed when this tool is the active tool in the OnContext method.

If your tool displays a custom context menu, it should let the application know that it handled the OnContextMenu event by returning True from the OnContext function. If you don't do this, the standard context menu will be displayed after your custom context menu.

This method does not fire in ArcGIS Engine. A context menu is implemented using IToolbarMenu in ArcGIS Engine as illustrated by the ControlsEditingSketchContextMenu command.
