How toolbars work

217

You cannot drag and drop toolbars between the document window and the Dreamweaver 
workspace frame. 

■

Toolbars remain a fixed size. A toolbar does not shrink if the container shrinks or if other 
toolbars are placed next to it. 

■

You can show or hide toolbars from the View >Toolbars menu.

■

Toolbars cannot overlap. 

■

Only the outline of the toolbar appears while you drag it. 

On the Macintosh, toolbars are always attached to the document window. They can be shown 
or hidden from the menu, but you cannot drag and drop, rearrange, or undock them.

How toolbar commands work

When Dreamweaver draws a toolbar, the following events occur: 

1.

For each toolbar control item, Dreamweaver determines whether the 

file

 attribute exists.

2.

If the 

file

 attribute exists, Dreamweaver calls the 

canAcceptCommand()

 function to 

determine whether it should enable the control in the current context of the document. 

For the Document Title text box in the Dreamweaver toolbar, for example, the 

canAcceptCommand()

 function checks to see if there is a current DOM and if the current 

document is an HTML file. If both these conditions are true, the function returns 

true

 

and Dreamweaver enables the text box on the toolbar.

3.

If the 

file

 attribute exists, Dreamweaver ignores the following attributes, if they are 

specified: 

checked

, 

command

, 

DOMRequired

, 

enabled

, 

script

, 

showif

, 

update

, and 

value

.

4.

If the 

file

 attribute does not exist, Dreamweaver processes the attributes that are set for 

the toolbar control item: 

checked

, 

command

, 

DomRequired

, and so on.

For more information on specific item tag attributes, see 

5.

Dreamweaver calls the 

getCurrentValue()

 function on every update cycle, as specified by 

the 

update

 attribute, to determine what value to display for the control.

6.

The user selects an item on the toolbar.

7.

Dreamweaver calls the 

receiveArguments()

 function to process any arguments that the 

arguments

 attribute of the toolbar item specifies.
