DWFilenameFilter reference
The objects of type DWFilenameFilter are new to Dreamweaver CS5 and are used to restrict the files displayed in the
Related Files bar. To manipulate the related Files bar filter, extension developers can create a new DWFilenameFilter
object and change the behavior of the filter using the functions described in the following sections.
For example,
var filter = new DWFilenameFilter;
filter.setExpression('*.js');
dw.setRelatedFilesFilter(filter);
Extension developers can also manipulate the current filter applied to the Related Files bar by invoking the
dreamweaver.getRelatedFilesFilter() function (see “ dreamweaver.getRelatedFilesFilter() ” on page 190 )and
then changing the behavior of the filter using the other functions.
For instance,
var filter = dw.getRelatedFilesFilter();
filter.addExtensionToExclusionExpression('.js');
dw.setRelatedFilesFilter(filter);
