RE: [Plib-users] ComboBox Problems

[Clay, B. <bc...@ba...>]

Brian:
  I have had problems using the streams for debugging.  Things get
buffered so you may not see what you expect.  Try using fprintf(stderr,
... Instead or put a break point in the callback.  Also, if you are
doing this with C++ you may have to declare the  callback method as a
static method.

Subject: [Plib-users] ComboBox Problems


I am having a little problem with all of the selection objects
(puaComboBox,=20
selectbox, buttonBox).  I have posted this before but no one replied to
me,=20
hoping maybe you can help.  I declare the pointer in the header file.
Here=20
is where I set the combo box and start to use it:

char *listOne[] =3D { "First Entry", "Second Entry", "Third Entry",
"Fourth=20
Entry", "Fifth Entry", "Sixth Entry", NULL } ;

      choiceOne =3D new puaComboBox(30, 400, 230, 425, listOne, FALSE);
      choiceOne->setCallback(ChoiceOneCallback);

I have all of the necessary callbacks for keyboard and mouse.  You can
click=20
on the combobox and the menu drops down, however you can't select
anything. =20
If you use the up arrow on the keyboard (or down whichever) the program
will=20
crash.  However I have displayed that the combo box does have six items
in=20
it.  I think I have narrowed it down to the callback function for the=20
combobox, it never enters in there when something is selected:

void MainChoiceOneCallback(puObject *) {
       cout<<"HELLLOOOOOOOOO";
}
this will display nothing.  I have also tried changing the list for the=20
combobox within the callback and it doesn't change the display at all.
So=20
my question is why is it not entering the callback, is it a bug with=20
pui/puAux or is it my doing??  Thank you in advance.

-Brian
