timeline.expandFolder(bExpand [, bRecurseNestedParents [, index]])
bExpand A Boolean value that, if set to true, causes the method to expand the folder; false causes the method to collapse the folder. bRecurseNestedParents A Boolean value that, if set to true, causes all the layers within the specified folder to be opened or closed, based on the bExpand parameter. This parameter is optional. index A zero-based index of the folder to expand or collapse. Use -1 to apply to all layers (you also must set bRecurseNestedParents to true). This property is equivalent to the Expand All/Collapse All menu items in the Animate authoring tool. This parameter is optional.
Nothing.
Method; expands or collapses the specified folder or folders. If you do not specify a layer, this method operates on the current layer.
The following examples use this folder structure:
Folder 1 *** --layer 7 --Folder 2 **** ----Layer 5
The following example expands Folder 1 only:
fl.getDocumentDOM().getTimeline().currentLayer = 1;
fl.getDocumentDOM().getTimeline().expandFolder(true);The following example expands Folder 1 only (assuming that Folder 2 collapsed when Folder 1 last collapsed; otherwise, Folder 2 appears expanded):
fl.getDocumentDOM().getTimeline().expandFolder(true, false, 0);
The following example collapses all folders in the current timeline:
fl.getDocumentDOM().getTimeline().expandFolder(false, true, -1);
