Help in axlFormCreate

luanvn81

Hi all!

I have a problem with my form code as below.

here my code 

axlCmdRegister( "testfm" `get_database )
(defun get_database ()
axlSetFindFilter(?enabled '(noall VIAS NAMEFORM) ?onButtons '(noall VIAS))
axlVisibleDesign(nil)
axlVisibleLayer("VIA CLASS" t)
axlClearSelSet()
AllVias_check = axlGetSelSet(axlAddSelectAll())
axlClearSelSet()
test_frm()
);end defun

form = nil
(defun test_frm ()
Out_File_Form = outfile("./test_frm.form" "w")
.........
close(Out_File_Form)
form = axlFormCreate((gensym) "test_frm.form" nil '_form_Action t)
axlFormAutoResize(form)
axlFormDisplay(form)
);end defun form main

(defun _form_Action (form)
case(form->curField
("start"
printf("test %L\n", AllVias_check)
);end case start
...........
);end case all
);end defun

The problem occur when I click on Start button, variable "AllVias_check" return dbid: removed. But if I change  '_form_Action t  into '_form_Action nil  variable "AllVias_check" return list of dbib.  Please help me to understand it.

  • Hello Luan,

    Maybe the non-blocking form allows some other process that clears the dbid.

  • What is your goal with this code?

    First you select VIAs and after bring up a form. But what do you want to do next?

    The dbid removed has indeed to do with the non-blocking form. , When get_database() is finished Allegro returns to 'idle'. Since this code is called from the command line with 'testfm' the selection set and dbids are cleared at the moment it returns.

    If you call  get_database()  directly from the SKILL prompt the dibd's will most likely stay valid, until you do a 'done' or start another command in Allegro.

    Perhaps this is an other option: use a mini-status form ('options'  window) and use a while loop with axlEnterEvent() to do whatever you need to do. During this axlEnterEvent() the selection and dbids are valid.

    Look into the axlMiniStatusLoad() and axlEnterEvent() API description.

    Hi Bruekers!

    Thank for your reply.  I have resolved my problem. As your advice,  the dbib removed is caused by non-blocking form  and  calling 'testfrm'  after  get_database()  make dbids are cleared.

    By the way, my code use to check  via types (with different sizes)  is not allow exist in out of constraint region.

    Thank you.

    Luan.

    Hi Leto!

    You are right, the non-blocking form cause the dbids are  cleared. And my code works.

    Thank you.

    Luan.
