2024.0. "simple_text & TAB key" by TAVHLT::DORON (Doing my BEST !!!) Wed Jan 10 1990 12:27

Hi,

 I have written a simple C program that is using a UID compiled file in order to
get 3 text fields. The text fields are 3 simple_text widgets the are children of
a popup_dialog_box widget. Moving from one field to another by the pointer
(mouse) is done w/o any problem, but, doing it with the TAB key produces 2
lost_focus events. My question is, why 2 events and not 1 (like the mouse
selection)? Is it a bug? If yes how can I work around it? If not, what is wrong?
I have tried it versions 1 & 2 of DECwindows.

			Thanks in advance,

 The UIL object declaration looks like:

.
.
.

object
   n_form : popup_dialog_box {
      arguments {
	 take_focus	= true ;
         x		= 100 ;
         y		= 70 ;
      };
      controls {
	 simple_text	n_x1 ;
	 simple_text	n_y1 ;
	 simple_text	n_z1 ;
      } ;
   };                                


object
   n_x1 : simple_text {
      arguments {
	  x	= 10 ;
          y 	= 10 ;
	  width = 40 ;
	  max_length 	= 9 ;
      } ;
      callbacks {
	  lost_focus = procedure CallBack( C_X1 );
      } ;
   } ;

.
.
.

  I can't recall which conference, but this was discussed somewhere.  I do
recall something about there being two different reasons activating the
LostFocus callback, and if I'm not mistaken the reasons were NotifyGrab and
NotifyWhileGrabbed.

  Hope this helps some...

I am afraid this does not help. Can any one relate?


				Thanks,

  In this conference and in HARBOR::DECWINDOWS_PROGRAMMING and in
CLT::DECWTOOLKIT try doing a DIR/TITLE=LOST.  I know this will start you on
your way...

Thanks,

 There  is a dicussion about it in the DECWINDOWS_PROGRAMMING (95).
