EXTENDING DREAMWEAVER CS4

Toolbars

Attributes

id, {showIf}

• id="id_reference" Required. Must be the ID of an item that was previously defined or included in the file.

Dreamweaver does not allow forward references. If a toolbar item tag references an undefined ID, Dreamweaver

reports an error and ignores the reference.

• showIf="script" Specifies that this item appears on the toolbar only if the specified script returns a true value.

For example, you can use

showIf to show certain buttons only in a given application or only when a page is written

in a server-side language such as Adobe ColdFusion, ASP, or JSP. If you do not specify

showIf, the item always

appears. Dreamweaver checks this property whenever the item’s enabler runs; that is, according to the value of the

update attribute. You should use this attribute sparingly. The attribute can be used either in the item definition or

in a reference to the item from a toolbar. If both the definition and the reference specify the

showIf attribute,

Dreamweaver shows the item only if both conditions are true. The

showIf attribute is equivalent to the showIf()

function in a command file.

Contents

None.

Container

The toolbar tag or the toolbarset tag.

Example

Description

Inserts a separator at the current location in the toolbar.

Attributes

{showIf}

• The showif attribute specifies that the separator should appear only on the toolbar if the given script returns true.

For example, you can use the

showIf attribute to show the separator only in a given application or only when the

page has a certain document type. If the

showIf attribute is unspecified, the separator always appears.

Contents

None.

Container

The toolbar tag.
