Hi again: I have my entry widget as posted before:
(mk-button-ex ("Change!"
(let* ((pmutil-gui (fm^ :pmutil-gui))
(pm (selected-pm pmutil-gui)))
(when pm
(let ((callsign (fm^v :callsign-entry)))
(set-status pmutil-gui +PMUTIL-GUI-STATUS-
SETTING-CALLSIGN-IN-PM+)
(setf (new-callsign pmutil-gui)
(subseq callsign
0
(min (length callsign)
+PMIO_MAX_CALLSIGN_LENGTH+)
))
(set-status pmutil-gui +PMUTIL-GUI-STATUS-
READY+)))))
:id :callsign-entry-btn
;; :state (c? (if (pm-selected-p (fm^ :pmutil-
gui)) <--- My intended functionality
;; 'enabled ;; 'disbled)):state (c? (if 1 <-- Simple test
'enabled
'disbled))
:background (c? (background .parent))
:parent-x 589
:parent-y 320
:tile? nil)
As soon as I put the :state part in I get the following error:
the assertion (NOT (CFFI-SYS:NULL-POINTER-P CTK::SELF-TKWIN)) failed.
[Condition of type SIMPLE-ERROR]
I wasn't able to get a real trace/debug approach to this one ... I
assume this has to do with the order of widget creation. I am sure I
have used this before, so I haven't a clue what's wrong there. Oh
my ... ?!
Any help really appreciated... Frank
