abstract OO.ui.Tool

Constructor

new OO.ui.Tool(toolGroup, [config])abstract #

Tools, together with toolgroups, constitute toolbars. Each tool is configured with a static name, title, and icon and is customized with the command to carry out when the tool is selected. Tools must also be registered with a tool factory, which creates the tools on demand.

Every Tool subclass must implement two methods:

Tools are added to toolgroups (ListToolGroup, BarToolGroup, or MenuToolGroup), which determine how the tool is displayed in the toolbar. See toolbars for an example.

For more information, please see the [OOUI documentation on MediaWiki][1]. [1]: https://www.mediawiki.org/wiki/OOUI/Toolbars

Parameters:

Name Type Attributes Description
toolGroup OO.ui.ToolGroup
config Object optional

Configuration options

Properties:
Name Type Attributes Description
title string | function optional

Title text or a function that returns text. If this config is omitted, the value of the static title property is used.
displayBothIconAndLabel boolean optional

See static.displayBothIconAndLabel
narrowConfig Object optional

See static.narrowConfig

The title is used in different ways depending on the type of toolgroup that contains the tool. The title is used as a tooltip if the tool is part of a bar toolgroup, or as the label text if the tool is part of a list or menu toolgroup.

For bar toolgroups, a description of the accelerator key is appended to the title if an accelerator key is associated with an action by the same name as the tool and accelerator functionality has been added to the application. To add accelerator key functionality, you must subclass OO.ui.Toolbar and override the getToolAccelerator method.

icon #

The symbolic name of the icon (e.g., ‘remove’ or ‘menu’), or a map of symbolic names. A map is used for i18n purposes and contains a default icon name and additional names keyed by language code. The default name is used when no icon is keyed by the user's language.
