Re: Field Validation in Listboxes

[Kirk Brooks via 4D_Tech]

Jeff,

I think you want to use EDIT ITEM.

$objName:=OBJECT Get name(Object current)  //  will be the name of the
listbox object even if called from a column/array
$row:=listbox_get_rowcolumn ($objName;->$column;->$objPtr)  // method gets
the row and ptr to the column & column object

If(Not( code to test the input is ok))

EDIT ITEM($objPtr->;$row)

End if


This works in the listbox object or the array within the listbox.

Field Validation in Listboxes

[Jeff Grann via 4D_Tech]

What is the best practice for validating data entry in listbox fields (cells)?

If the user enters an invalid value, I’d like to keep them in the field, but 
REJECT doesn’t seem to work in listbox cells.

COllections

[Chip Scheide via 4D_Tech]

a record can store any native type of data supported by 4D, and a blob 
(also available as a record field) can store other types of data such 
as an array.

It seems to me (at this point), that a collection is just a record, 
perhaps it is more flexible, being definable on the fly, but still a 
record.

Any one who has more insight?

Chip

Re: overlapping subforms

[Kirk Brooks via 4D_Tech]

Piotr,
This sounds like a creative use of subforms. But it also sounds pretty
complex. So the first thought I offer is to look at what you are trying to
do and be sure using subforms in actually the best solution. It may be but
there may also be another approach that results in the same UI.

For example, you could use OBJECT SET SUBFORM
 to
and simply change the displayed subform as required instead of managing
multiple subform objects.

The version you are using also may matter. But to answer the question you
asked:

​First I'm assuming all 3 of these subforms are on the parent form and not
nested (a subform on a subform) AND on the same form page. Also, are the
subform objects, the variables that contain the subforms, process variables
or form variables?

If the subform you are trying to display is on page 0 it would create this
issue. Either put all the subforms on page 0 or put a subform on each page
for this purpose. Remember you can use
​
​Are you using OBJECT DUPLICATE
 to
add subforms? If so remember to ​specify the "boundTo" object. This param
lets you manage the z order of the objects. If you don't use it the new
object is at the top of the stack. This could account for the issue.

The other possibility is the context. When you say "press a button" where
is that button? This is important.

If it is on the parent form you really shouldn't have a problem.

If it's on a subform you may be opening the popup subform within the
subform with the button because the button on the subform runs in the
context of the subform - not the parent form. This can be quite confusing.

Remember that the form events on a subform run BEFORE the parent form. So
an On clicked event from a button on a subform runs:
1) in the subform button

2) the subform form method

3) the subform container (which is the 'subform object' on the parent form)

4) the parent form method


You can see it as a kind of popup viewer

​The subform pops up - is it displaying fields from a record (which record)
or something like a list, variables etc?​

​What does "save the form" mean? Saving the parent form or the subform?

Hi,

I’m sitting in in the master class by Laurent in Paris.

Absolutely fantastic, if you haven’t booked for Washington yet you need to
break open the piggy bank now and book!

Really good stuff.

RE: overlapping subforms

[Piotr Chabot Stadhouders via 4D_Tech]

Hi,

Yes, I am sure I set it to the front, but when I do a "Save Form" the subform 
goes to the back again
I also tried setting the other subforms to invisible, and making the 4th 
subform visible
This also doesn’t work always
Maybe this problem has to do with some other facts :
I use a webarea in the 4th subform, and I also resize the subform before making 
it visible

Does anybody know of redraw problems when using a webarea in a subform?

Gr,

Piotr
