[repost] v13+ Object (not C_Object) references from a Component
If a component method is called from the Host system, where a Text is
passed to the component method which is an object Identifier (ex:
"obj_Accept_button" - which is the object name of a button on an entry
form)
can/does the component reference the host system object?
Ex :
Host system Form Object method:
my_Component_Method("obj_Accept_Button")
Component Method: - my_Component_Method:
$Object_Name:=$1
OBJECT GET BEST SIZE($Object_Name;$Best_Width;$Best_Height)
Will the component 'see' the host form object "obj_Accept_Button", or
will the component look for the object within the component and,
presumably, find nothing?
Thanks
Chip

Re: [repost] v13+ Object (not C_Object) references from a Component
Hi Chip, I know that using 4D v16 it is possible to use the OBJECT GET commands
to get information about the named objects. Not completely sure about versions
prior to 4D v16. I think some commands would work and some would not.
BTW, your example line for OBJECT GET BEST SIZE is missing the * as a 1st param
since you are using the name of the object.

Re: [repost] v13+ Object (not C_Object) references from a Component
I am unclear in what you are saying (sorry).
Are you saying:
... there exists, at least some, Form object commands which *will*
work, from inside a component method, on Host form objects?
I know that in the Host, Object Get commands will retrieve (or set for
Object Set) a variety of Object properties; and I believe if the Form
(and its objects) are part of a component that the same commands will
do the same thing for the component form.
What I am asking about - to be more clear (I hope) -
preferably for v13 (or v15)
When the Object GET/SET commands are called from a Component method, do
they recognize that an object referenced by name is on a Host form?
Thanks

Hi Chip, >>When the Object GET/SET commands are called from a Component method, do they >>recognize that an object referenced by name is on a Host form? I don't think they behave differently from between v13 and v17. So a quick answer is yes. Suppose your component method is // Method: obSetTitle C_TEXT($1;$2) OBJECT SET TITLE(*;$1;$2) If you host form has a button with object method that executes: obSetTitle (OBJECT Get name(Object current);"Hello") The button title will change accordingly.
