290 Floating Panels

How floating panel files work

Custom floating panels can be moved, resized, and tabbed together the same way as the

floating panels that are built in to Dreamweaver. Custom floating panels differ from built-in

floating panels in the following ways:

■ Custom floating panels display in the default gray. Setting the BGCOLOR attribute in the

BODY tag has no effect.

■ All custom floating panels either appear always in front of the Document window or float

behind it when inactive, depending on the setting for All Other Floaters in the

Panels preferences.

Floating panel files also differ somewhat from other extensions. Unlike other extension files,

Dreamweaver does not load floating panel files into memory at startup unless the floating

panels were visible when Dreamweaver last shut down. If the floating panels were not visible

when Dreamweaver shut down, the files that define them are loaded only when referenced

from one of the following functions:

dreamweaver.getFloaterVisibility(),

dreamweaver.setFloaterVisibility(), or dreamweaver.toggleFloater(). For more

information on these functions, see the Dreamweaver API Reference.

When one of the files inside the Configuration folder calls the

dw.getFloaterVisibility(floaterName), dw.setFloaterVisibility(floaterName),

dw.toggleFloater(floaterName) functions, the following events occur:

1. If floaterName is not one of the reserved floating panel names, Dreamweaver searches the

Configuration/Floaters folder for a file called

floaterName.htm. (For a complete list of

reserved floating panel names, see the

dreamweaver.getFloaterVisibility() function

in the Dreamweaver API Reference. If

floaterName.htm is not found, Dreamweaver

searches for

floaterName.html. If no file is found, nothing happens.

2. If the floating panel file is being loaded for the first time, the initialPosition() function

is called, if it is defined, to determine the floating panel’s default position on the screen,

and the

initialTabs() function is called, if it is defined, to determine the floating panel’s

default tab grouping.

3. The selectionChanged() and documentEdited() functions are called on the

assumption that changes probably occurred while the floating panel was hidden.
