Re: What's the widget's variable name?

mh, may be I don't understand what the problem is.
But anytime I want to know the variable name in a GUI I use Self which gives
you a pointer to the variable.
Very simple and reliable.

Any reason why this simple solution is not working?

Re: What's the widget's variable name?

Self is deprecated in v12. It's replaced by Object Current or Focus Object
or whatever.
The problem is that the variable is dynamic. Yes, Self gives you a pointer
to the variable. But I need to find out WHICH variable the pointer refers
to and whether it is the search object variable. But I don't know what the
search object variable's name is because its name is assigned dynamically
each time the form is loaded. So one time the variable might be
called $form.5.C and another time it might be $form.9.C or $form.10.C or
whatever. I do not care what the CONTENT of the variable is. I need to know
if the variable whose data was just modified is the search object variable,
which might be named $form.9.C or $form.5.C or something else..

Re: What's the widget's variable name?

If you know the search object's Object Name, you can match that with the
object's Variable Name using FORM GET OBJECTS.

(Caveat: haven't tried it doing what you're doing though).

Re: What's the widget's variable name?

Nope - doesn't work because (I guess) the variable that you enter the
search into, which is PART of the search object, is on a subform.

again, that is not a problem at all.
we don't need to know the name of a dynamic variable, ever.

I think the real problem is that,
if I understand correctly,
you prefer to put all code in the form method, not the object method.

the whole point of using widgets is that it abstracts a collection of form objects and represent it as a
single variable.

you really shouldn't care about what event fired in which object inside the widget, at all.
it could be On Data Change, On After Edit, On Click, On Double Click, On Timer...
but the bottom line is, regardless of what really happened inside the widget,
if the event qualifies as updating the bounding variable,
an On Data Change event is sent to the container.

in your case, the actual event that fired inside the widget happens to be On Data Change,
which is a bit confusing,
but I think the search picker catches On After Edit as well,

Re: What's the widget's variable name?

Hi Pat,
thanks for your explanation, I missed that Self is deprecated ;)
On the other hand I agree with Miyako. To me it sounds like you see a
problem which actually doesn´t exist.

Although it doesn't seem to be quit forward how to use this widget.

Re: What's the widget's variable name?

Hi all,

Self is not deprecated at all.. It's exactly the same command as
Object get pointer. Both commad do exactly the same thing
As you may have noticed, Self command has not been converted to
'Object get pointer' in your old code when converting to v12. 'Object
get pointer' is a new command that respect new naming rules.

'Self' has been kept because it is far more easy to write than the
'Object get pointer'. I usually use the first without parameter and
use the second with parameters.
//
$ptr1:=Self
$ptr2:=OBJECT Get pointer(Object named;"Button15")
//
Even if I don't recommand this syntax,  you can do the following, it works fine

$ptr1:=Self(Object named;"Button15")
$ptr2:=OBJECT Get pointer(Object named;"Button15")

Amicalement,

Jérôme

Re: What's the widget's variable name?

Well, the manual says:
This command is kept only for compatibility reasons.
Starting with version 12 of 4D, it is recommended to use the OBJECT Get
pointer command.

This means, that sometime in the future, it will be killed. 
Thats the way 4D did it in the past.

Pretty sure it will not.. Otherwise, the new command would have taken
the place/number of the old one..

Re: What's the widget's variable name?

I hear you, but I don´t think you are right.
We had many issues like that in the past. 

>>Otherwise, the new command would have taken...
not necessarily. Sometime 4D keeps similar commands side by side.

Yes, exactly. I need to handle it in the form method because there is code
in the On Data Change event which sets a flag if the data in any field or
variable on the form has been modified. But I do not want that flag set if
it's the search object's field that was modified - that does not count as a
data change in this context. So I need to know the name of the search
object's field in order to know if that was what was modified. The only way
to get that (as far as I can see) is to set it when that field is modified
- i.e., in the object's On Data Change event.:

RESOLVE POINTER(Focus
object;tQuickSearchVarName;$focustablenum;$focusfieldnum)
