Returns
Dreamweaver expects a Boolean value:
Example
The following example prevents the user from resizing the floating panel:
function isResizable()
{
return false;
}
selectionChanged()
Description
Called when the floating panel becomes visible and when the selection changes (when focus switches to a new
document or when the insertion point moves to a new location in the current document). This function should be
defined only if the floating panel must track the selection.
Note: Define
selectionChanged()
Arguments
None.
Returns
Dreamweaver expects nothing.
Example
The following example of
selectionChanged()
whether the selection is a script marker. If the selection is a script marker, Dreamweaver makes the
AP element visible. Otherwise, Dreamweaver makes the
function selectionChanged(){
/* get the selected node */
var theDOM = dw.getDocumentDOM();
var theNode = theDOM.getSelectedNode();
/* check to see if the node is a script marker */
if (theNode.nodeType == Node.ELEMENT
theNode.tagName == "SCRIPT"){
document.layers['blanklayer'].visibility = 'hidden';
document.layers['scriptlayer'].visibility = 'visible';}
else{
document.layers['scriptlayer'].visibility = 'hidden';
document.layers['blanklayer'].visibility = 'visible';
}
}
About performance
Declaring the
selectionChanged()
Dreamweaver performance adversely. Consider that the

important to use different scenarios to test your floating panel, using large documents (100 KB or more of HTML)
whenever possible, to test performance impact.
