The ToolBarButton toolbar element defines a toolbar button in a Maplet application.

The ToolBarButton element features can be modified by using options.  To simplify specifying options in the Maplets package, certain options and contents can be set without using an equation. The following table lists elements, symbols, and types (in the left column) and the corresponding option or content (in the right column) to which inputs of this type are, by default, assigned.

A ToolBarButton element can contain Action or command elements to specify the onclick option and an Image element to specify the image option.

A ToolBarButton element can be contained in a ToolBar element.

The content of a ToolBarButton can be any number of ToolBarButton or ToolBarButtonItem descriptions, or in general, any element which extends the ToolBarButtonInterface.

The following table describes the control and use of the ToolBarButton element options.

An x in the I column indicates that the option can be initialized, that is, specified in the calling sequence (element definition).

An x in the R column indicates that the option is required in the calling sequence.

An x in the G column indicates that the option can be read, that is, retrieved by using the Get tool.

An x in the S column indicates that the option can be written, that is, set by using the SetOption element or the Set tool.

The opts argument can contain one or more of the following equations that set Maplet application options.

caption = string or symbol

The caption that appears on the toolbar button.  By default, it is the string OK.

enabled = true or false

Whether a toolbar button can be clicked.  If enabled is set to false, the toolbar button is dimmed, and any action associated with it cannot be initiated.  By default, the value is true.

image = Image element or reference to an Image element (name or string)

An image on the toolbar button.

onclick = Action or command element, or reference to an Action element (name or string)

The action that occurs when the toolbar button is clicked.

reference = name or string

A reference to the ToolBarButton element.

If the reference is specified by both an index, for example, ToolBarButton[refID], and a reference in the calling sequence, the index reference takes precedence.
