At design, add a width_assign() method. Set autosize = .t..

In the Init() event, save nWidth as startup width. In width_assign(), intercept the new value and adjust up/down based on new width to nWidth comparison, and re-save nWidth.

You'll need the nWidth value to know how it's changed as there's a feature-not-a-bug in VFP that accesses to left, top, width, height will also call assign code as well. There are times the "new width" will be the old width re-stored for some feature-not-a-bug reason.

You can create a custom class for this and use it wherever you need this resize ability. You can also create a discriminating class which will behave in one of N ways based on an nType setting, where nType=1 means resize form, nType=2 means reduce/enlarge font size, etc.
