2970.0. "Have anybody get focus?" by ZUDEV1::CASAULTA () Thu Jun 21 1990 06:35

	Dear Notes Users,

	Finally I arrive to put my little problem, I couldn't solve until 
	now, in this note.

	Some of our customers are developing a buisness application under
	DECwindows and VAX/VMS V5.3 using the Xlib, Xtoolkit and DECwindows 
	Toolkit at the same time. It's there were we encountered some very
	ennoying focus problems.

	The szenario: from the main part of the application a popup dialog
	box will be invoked which controls one or more simple text widgets.
	The very first of these simple text widgets is sensitive in the 
	sense that, when you click the mid mouse button on it or when you
	press a predefined function key on it at the moment this text widget 
	has input focus, a popup dialog box will appear controlling itself
	a list box.
	Selecting an item out of this list box, the list box and its parent
	popup dialog box will disappear returning the input focus to the
	previous popup dialog box controling all the simple text widgets.

	Now, just there is our problem! We don't succeed in returning the
	input focus to the very first simple text widget from where we've
	called the "popup list box"!

	Has anybody an idea how we could manage to return the input focus
	from the disappearing "popup list box" to the very first simple text
	widget? Or, how could we trace the input focus to see where we might
	run into problems?

	I would appreciate very much any clue given to my problem.

	Thanks, Martin.

	

Try XtCallAcceptFocus on the widget you want.

    
    	We have already used the XtCallAcceptFocus routine! And too, it
    	works in the sense that when clicking within the first popup
    	dialog box the input focus will be returned to the widget we've
    	specified as parameter to the XtCallAcceptFocus.
    
    	The real problem is that the input focus is kept by the popup
    	dialog box (the associated title bar change to active) until you 
    	change this state "manually".
    
    	Any further suggestions?
    
    	Martin.
