bug in focus management

bug in focus management

[Stan Pinte]

hello,

I guess we have a bug in our focus management code, in guile-gtk-1.2-0.31.

Indeed, when a widget has the focus, a call to (gtk-widget-get ref-entry 'has-focus) returns #f.

the following code should proof the point.

Any idea?

thanks a lot,

Stan.

(use-modules (ice-9 format))
(use-modules (gtk gtk))

(let ((window (gtk-window-new 'toplevel))
      (button (gtk-button-new-with-label "Say Hello"))
      (ref-entry (gtk-entry-new)))
  (gtk-widget-set-name button "mybutton")
  (gtk-widget-set-name window "mywindow")
  (gtk-window-set-title window "Guile-Gtk: Hello World")
  (gtk-container-border-width window 10)
;  (gtk-container-add window button)
  (gtk-container-add window ref-entry)
  (gtk-signal-connect ref-entry "insert-text"
		      (lambda (new-text new-length position)
			(if (string? new-text)
			    (format #t "inserted: [~c]~%" (string-ref new-text 0))
			    (format #t "not text!!!~n"))))
	;;;shows the problem

  (gtk-signal-connect ref-entry "focus-in-event"
		      (lambda (entry)
			(format #t "focused [~A]. Has focused: ~A ~%" 
				ref-entry
				(gtk-widget-get ref-entry 'has-focus))))

	;;;end of problem

  (gtk-widget-show-all window)
  (gtk-standalone-main window))

Try 'has_focus instead of 'has-focus.  Also, the focus flag seems to
be set only after the "focus-in-event" handler has returned.  Try
printing the focus flag from the "insert-text" handler to observe
this.

indeed, calling 'has_focus after the "focus-in-event" does the trick!!!!

thanks a lot,

Stan.

It is weird, though, because the property is documented as "has-focus" in the Gtk docs...

Is this normal? Is there a rule to guess the right form?

Stan.

I have no idea.  I just tried a few things and suddenly one of them
worked.  I also looked at (gtk-widget-flags ...) to find out about the
has-focus flag.
