javascript - ExtJS change mask target while opening an Ext.Window -

-

i have extjs application , want change mask target while showing ext.window. when show window, entire dom masked, want mask div. overriding getmasktarget not working, gets target through ext.panel.header.

maybe can setup window modal: false , mask component / element in window show event handler (remove mask in hide or destroy event handler depending on closeaction)?
