53.0. "Changing focus from a callback" by INFACT::DATZMAN (Indianapolis Field Applications Center) Fri Jan 27 1989 14:29

    Is there a was to make a window come into focus into focus from
    a callback?  I looked at the xtcallacceptfocus routine but it
    is C only.  I need to do this using UIL and PL/I.
    
    Any help is much appreciated.

	That's a documentation error. There is an XT$CALL_ACCEPT_FOCUS routine. It takes a Widget by reference and an X Time by reference. Leo
53.2	XT$CALL_ACCEPT_FOCUS ?	INFACT::DATZMAN	Indianapolis Field Applications Center	`Wed Feb 01 1989 08:32`	10
	I searched all of the DECW*.PLI files in sys$library but did not see a XT$CALL_ACCEPT_FOCUS declaration. I did see a dcl dwt$accept_focus_proc pointer based; declaration. Where might I find what is meant by an X time? What value would one use if one wanted the new window to take focus after the callback had completed? Thanks. Dick

This was an intrinsics procedure added very late in the game... It's in the code, but I guess it didn't make the documentation or the language definition files. > Where might I find what is meant by an X time?

It comes back in most events, which is where you need to get it from. It's defined in decw$include:x.h "Time". The various event data structures are defined in decw$include:xlib.h. Leo
53.4	Alternative to C??	INFACT::DATZMAN	Indianapolis Field Applications Center	`Tue Feb 07 1989 14:15`	5
	It there an alternative way? My customer is trying to do this using PL/I, not C. Dick
53.5	do it yourself, until it's on the kit	PSW::WINALSKI	Paul S. Winalski	`Tue Feb 07 1989 14:22`	8
	RE: .4 Of course there's an alternative way. Using the .h file as a guide, write up a PL/I version of the data structure and routine declarations and include them in your code. --PSW
53.6	which event	INFACT::DATZMAN	Indianapolis Field Applications Center	`Tue Feb 07 1989 15:22`	5
	Ok, I'm game. What event should I use to cause another widget to receive input focus? XFocusInEvent? Dick
