Error in version R2014a.
The name 'userdata' is not an accessible property for an instance of class 'com.mathworks.widgets.desk.DTDocumentContainer'.
This function is awesome!
Apparently the dock group window remembers its last layout (i.e. how many tiles it has and where they are located).
Is it possible to control which tile a given figure goes into?
This is exactly what I was searching for!
1) add functionality to close these docked group windows groups! ('close all' doesn't do the trick, as the group container remains)
2) keep the grouped windows from populating Matlab's Desktop menu list (The drop down alongside File | Edit | Debug |... ). It seems to include every single grouped window I create :(
