java.lang.Object com.esri.arcgis.framework.Tool
public class Tool
Tool CoType.
A Tool acts as a button that allows further interaction with the application's display. The Zoom In command is a good example of a tool--you click or drag a rectangle over a map before the display is redrawn to show the map contents in more detail. Toosl can only be placed on toolbars.
To create a custom Tool object, implement both esriSystemUI.ICommand and esriSystemUI.ITool.

public boolean isEnabled() throws IOException, AutomationException
When implementing ICommand to create a custom command, add some logic to the Enabled property to specify in what state the application should be in for the command to be enabled.
isEnabled
in interface ICommand
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public boolean isChecked() throws IOException, AutomationException
The Checked property indicates the state of this Command. If a command item appears depressed on a commandbar, the command is checked. The active tool will appear checked. Also commands that serve as a toggle will be checked when that toggle is on.
A system event is periodically called to set the state of the commands on the commandbars indicating which ones are checked.
isChecked
in interface ICommand
IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public String getName() throws IOException, AutomationException
The Name property of a command is a programmatic identifying name string. By convention, a command's name should include its category name. The format of the Name string should be <Category>_<Caption>. For example, the name of the builtin ArcMap command About ArcMap is "Help_About". Since it is an identifier of the command, the Name property should not be localized.
When implementing ICommand to create a custom command, use the Name property to set the internal name of this command.
Note, the Caption property of a command is the string that appears when the command is placed on a command bar.
public String getName () {return "MyCustomTool_MyTool";}

IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public String getCaption() throws IOException, AutomationException
The Caption property of a command is the string that appears when the command is placed on a command bar.
When implementing ICommand to create a custom command, use the Caption property to set the caption of the command.
public String getCaption() {return "MyTool";}

IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.public String getHelpFile() throws IOException, AutomationException
The HelpFile property is used to specify the name of the help file that contains the context sensitive help topic for your custom command.
If you set both the HelpFile and HelpContextID properties, then an end-user of your command can use the "What's This?" command in ArcMap or ArcCatalog to get help on your command. Note, if you want your What's This help to look and behave the same as the standard ArcGIS commands, then you should create a WinHelp file instead of a HTMLHelp file.
If you have a WinHelp file (*.hlp), set ICommand_HelpFile to the name of the help file containing the topic that describes the command and set ICommand_HelpContextID to the topic ID's mapped numeric value. The topic ID is the so-called # footnote in the RTF file you include in your WinHelp file. You can use Help Workshop to add this numeric value by opening the HPJ file, clicking Map and then clicking Add (to add the mapping for an individual topic). See the help topic "To enable a program to display an individual Help topic" in the Help Workshop's help file.
If you have an HTMLHelp file (*.chm) the procedure is similar; specifiy the .chm file as ICommand_HelpFile and the mapped numeric value as ICommand_HelpContextID. Popup topics are problematic with HTMLHelp, but the help topic will display in a default or user-defined window.
As part of your deployment strategy register the name of the WinHelp file (*.hlp) as a new string value in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Help
Or if you're working with a HTMLHelp file (*.chm) register its name as a new string value in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\HTMLHelp.
Note, if you want to create a custom command that launches your help system, you can call an entire help file and/or use the functionality of the appropriate Help APIs by declaring and using the Windows API WinHelp() function or HTMLHelp() function.
Once you have one of these help functions declared, the OnClick event of your command could call the help function.

public int getBitmap() throws IOException, AutomationException
When implementing ICommand to create a custom command, use the Bitmap property to set the bitmap to be used as the icon on this command. In your Visual Basic project for this command, the bitmap can be stored in a resource file or in a PictureBox control on a form.
You must use a Bitmap file (.bmp) for the Bitmap property; Icon files (.ico) are not supported. Bitmap files should be 16 X 16 pixels. The color of the upper left pixel of the bitmap is treated as the transparent color. For example, if the upper left pixel of the bitmap is red, then all of the red pixels in the bitmap will be converted to transparent.
When a command is put on a toolbar, the command is displayed with the bitmap only by default; the display type is set to Image Only (ICommandItem::Style = esriCommandStyleIconOnly). When a command is put on a menu, the command is displayed with the bitmap and caption by default; the display type is set to Image and Text (ICommandItem::Style = esriCommandStyleIconAndText). However, if the Bitmap property is not set for this command, then the command will be displayed with the caption only by default when it is put on a toolbar or menu; the display type is set to Text Only (ICommandItem::Style = esriCommandStyleTextOnly).
When implementing ICommand to create a custom command, there is no need to implement this method. In the custom Java Command class, set the bitmapPath String to the physical location of the bitmap file to be used on the toolbar.
bitmapPath = "/images/mybitmap.bmp";
You must use a Bitmap file (.bmp); Icon files (.ico) are not supported. Bitmap files should be 16 X 16 pixels. The color of the upper left pixel of the bitmap is treated as the transparent color. For example, if the upper left pixel of the bitmap is red, then all of the red pixels in the bitmap will be converted to transparent.
When a command is put on a toolbar, the command is displayed with the bitmap only by default; the display type is set to Image Only (esriCommandStyles.esriCommandStyleIconOnly). When a command is put on a menu, the command is displayed with the bitmap and caption by default; the display type is set to Image and Text (esriCommandStyles.esriCommandStyleIconAndText). However, if the Bitmap property is not set for this command, then the command will be displayed with the caption only by default when it is put on a toolbar or menu; the display type is set to Text Only (esriCommandStyles.esriCommandStyleTextOnly).

AutomationException
- If the ArcObject component throws an exception.public void onCreate(Object hook) throws IOException, AutomationException
hook is a reference to an IApplication object or any of the Controls.
The OnCreate method gives the command a hook into the application.
When implementing ICommand to create a custom command, use the OnCreate method to get a hook to the application.
When you implement ICommand to create a custom command, you will find that your class constructor and destructor are called more than once per session. Commands are constructed once initially to get information about them, like the name, bitmap, etc and then they are destroyed. When the final, complete construction takes place, the OnCreate method gets called. OnCreate gets called only once, so you can rely on it to perform initialization of member variables. You can check for initialized member variables in the class destructor to find out if OnCreate has been called previously.
