# Command Images

###### Identifier:

org.eclipse.ui.commandImages

###### Since:

3.2

###### Description:

The images extension point provides a way of linking different types of images and icons to a particular command. These images can be used, as appropriate, wherever the command appears in the user interface. To accommodate some boundary cases (e.g., tool bar drop-down items), it is possible to group the images for a particular commands into "styles". These styles can then be specifically requested when a command is to be displayed.

Commands placed in menus using the org.eclipse.ui.menus extension point will use the default image if available, and commands placed in a toolbar will use the `toolbar` style images if available, followed by the default images.

The images to associate with a particular command.

- commandId - The identifier of the command with which the images should be associated.
- icon - The path to the icon which should be used in the default case, or the `ISharedImages` constant. This will appear when the icon is enabled and mouse is not hovering over it. It will also be used in any situation where such a more specific icon is not available.
- disabledIcon - The icon to display when the command is disabled.
- hoverIcon - The icon to display when the user is hovering over the command.
- style - The particular scenario in which this block of icons apply. For example, it may be desirable to have different icons when the command is displayed as a toolbar drop-down item. Currently the org.eclipse.ui.menus extension will use the default style (no style) for menu icons and the `toolbar` style for toolbar contributions. If no `toolbar` entry is available for that command, it uses the default style.

###### Examples:

    <extension
     point="org.eclipse.ui.commandImages">
     <image
      commandId="org.eclipse.example.ProfileLast"
      hoverIcon="icons/full/etool16/profile.gif"
      disabledIcon="icons/full/dtool16/profile.gif"
      icon="icons/full/etool16/profile.gif" />
     <image
      commandId="org.eclipse.example.ProfileLast"
      hoverIcon="icons/full/etool16/history.gif"
      disabledIcon="icons/full/dtool16/history.gif"
      icon="icons/full/etool16/history.gif"
      style="toolbar" />
    </extension>

###### API Information:

Within the workbench, it is possible to get images for commands using the `org.eclipse.ui.commands.ICommandImageService` interface. This interface can be retrieved from supporting workbench objects, such as `IWorkbench` itself, the `IWorkbenchWindow`, or the `IWorkbenchPartSite`. To retrieve the service, you would make a call like `workbench.getService(ICommandImageService.class)`.
