A simple toolbar command file

This simple example implements a Title text box item as seen on the Dreamweaver Document

toolbar. The text box item lets the user enter a name for the current Dreamweaver document.

You can implement this toolbar example by performing the following steps:

■ Creating the text box

■ Writing the JavaScript code

Creating the text box

To add a toolbar to Dreamweaver, you place an XML file that contains the toolbar definition

in the Toolbars folder inside the Dreamweaver Configuration folder.

The following figure shows the Title text box:

The following toolbar

editcontrol item defines a text box that is labeled Title:

<EDITCONTROL ID="DW_SetTitle"

label="Title: "

tooltip="Document Title"

width="150"

file="Toolbars/MM/EditTitle.htm"/>

The tooltip attribute causes Dreamweaver to display Document Title in a tooltip box when

the user places the mouse pointer over the text box. The

width attribute specifies the size of

the field in pixels. The

file attribute specifies that the EditTitle.htm file contains the

JavaScript functions that operate on the text box. To see the full definition of the

Dreamweaver Document toolbar, see the main toolbar (

id="DW_Toolbar_Main") in the

toolbars.xml file.

Writing the JavaScript code

When the user interacts with the text box, it causes Dreamweaver to invoke the EditTitle.htm

command file in the Toolbars/MM folder. This file contains three JavaScript functions that

operate on the Title text box. These functions are

canAcceptCommand(),

receiveArguments(), and getCurrentValue().
