196 Menus and Menu Commands

The command is renamed in the Commands menu.

To delete a command you’ve created:

1. Select Commands > Edit Command List.

A dialog box appears, listing all the commands you can delete. (Commands that are in the

default Commands menu don’t appear on this list and can’t be deleted using this

approach.)

2. Select a command to delete.

3. Click Delete, and then confirm that you want to delete the command.

The command is deleted. The file that contains the code for the command is also deleted;

deleting a command does not simply remove the menu command from the menu. Be

certain that you really want to delete the command before you use this approach. If you

want to remove it from the Commands menu without deleting the file, you can find the

file in Configuration/Commands and move it to another folder.

4. Click Close.

How menu commands work

When the user clicks a menu with a menu item that contains a menu command, the following

events occur:

1. If any menuitem tag in the menu contains the dynamic attribute, Dreamweaver calls the

getDynamicContent() function in the associated Menu Commands file to populate the

menu.

2. Dreamweaver calls the canAcceptCommand() function in each Menu Commands file that

is referenced in the menu to check whether the command is appropriate for the selection.

■ If the canAcceptCommand() function returns a false value, the menu item is

dimmed.

■ If the canAcceptCommand() function returns a true value or is not defined,

Dreamweaver calls the

isCommandChecked() function to determine whether to

display a check mark next to the menu item. If the

isCommandChecked() function is

not defined, no check mark appears.

3. Dreamweaver calls the setMenuText() function to determine the text that should appear

in the menu.

If the

setMenuText() function is not defined, Dreamweaver uses the text that is specified

in the

menuitem tag.

4. The user selects an item from the menu.
