Description

Dreamweaver calls this function before the Components tab appears. Dreamweaver then calls the getSetupSteps()

function if the

setupStepsCompleted() function returns zero or a positive integer.

Arguments

None.

Returns

An integer that represents the number of setup steps the user has completed, as described in the following list:

• A value of either zero or a positive integer indicates the number of completed steps.

• A value of -1 indicates that all the necessary steps are complete, so the instruction list does not appear.

handleDesignViewDrop()

Availability

Dreamweaver MX.

Description

Handles the drop operation when the user drags a table or view from the Databases panel or a component from the

Components panel to the Design view.

Arguments

componentRec

• The componentRec argument is an object that contains the following properties:

• The name property is the name of the tree node item.

• The image property is an optional icon for the tree node item. If omitted, Dreamweaver MX uses a default icon.

• The hasChildren property is a Boolean value that indicates whether the tree node item is expandable: if true,

Dreamweaver MX displays the Plus (+) and Minus (-) buttons for the tree node item; if

false, the item is not

expandable.

• The toolTipText property is optional tool tip text for the tree node item.

• The isCodeViewDraggable property is a Boolean value that indicates whether the tree node item can be dragged

and dropped into the Code view.

• The isDesignViewDraggable property is a Boolean value that indicates whether the tree node item can be dragged

and dropped into the Design view.

Returns

A Boolean value that indicates whether the drop operation was successful: true if successful; false otherwise.

Example

The following example determines if the component is a table or view, and then returns the appropriate bHandled
