Re: [Dynapi-Help] Dynapi3 getContentWidth and Template

[Raymond I. <xw...@ya...>]

This might call for a setAutoSize() function on either
DynLayer or TemplateManager.

lyr.setAutoSize(true) // will adjust the size of the
layer everytime its content changes or a new child is
added.

lyr.setAutoSize(false) // will disable auto-resize

Sometime ago I had create such a function for use in
one of my test systems. Should this function be added
to DynLayer or to TemplateManager?
