[comp.windows.x] a few questions about the X related source on the SVR4

lpgc@eng.sun.COM ("Larry Cable, Intrinsics based toolkit group, Sun Microsystems.") (05/28/90)

	Hi Chris,

	I am one of the developers working on the Sun version
	of AT&T's Xt+ toolkit, called OLIT (OpenLook Intrinsics
	Toolkit), I'd like to try and take a shot at answering
	some of your questions.

>Can anyone comment on the compatibility between Sun's Xt+ toolkit, 
>AT&T's SVR4 Xt+ toolkit, and the regular X11R4 Xt toolkit ?

	I think you may be a little confused here, but let me try
	to cover all the bases ...... The Xt toolkit, commonly
	known as "the Intrinsics", are a toolkit builders toolkit
	the 'toolkits' available today consist of a collection
	of user interface components (widget sets) built on the
	Intrinsics. When we ship OLIT with V2 of OpenWindows it
	will be based on "vanilla" R4 Intrinsics from MIT with
	'fixes' 1 through 11 applied .... i.e we will be 100% 
	'compatible' with the up to date Intrinsics from MIT .....
	I am not at liberty to comment on AT&T's plans to ship 
	an R4 based widget set, but they have the same code we
	have.

	As I understand it the 'current' code on the SVR4 tape 
	is based upon an R3.5 version of the Intrinsics (In a
	similar fashion to Motif ....) this is due, in both cases,
	to the emergence of Gadget support post R3 ....

	If you are confusing the Athena widget set with the
	'MIT R4 Xt Toolkit' then we are as 'compatible' as
	any other two widget sets are with each other .... 


	ButtonStacks are indeed mentioned in the documentation
	and in the code, they are there for backwards compatibility
	only ..... you should not use them .... since they are no
	longer part of the OpenLook specification.

>SVR4 comes with X11R3.
>Do I have to make the entire X11R3 tree so that I will have a version
of X11R3 to make
>the AT&T stuff with ?


	I have linked the R3.5 Intrinsics and Xt+ from AT&T with
	an R4 environment ..... and it seems to work in some
	cases .... alhtough doing so will obviously introduce
	the possibilty of incompibilities  ..... 
	
	but it will work!



	Hope this helps ....


	Rgds
