Re: Splitter help

[Douglas von Roeder via 4D_Tech]

John:

I've got something similar set up. The splitter needs to be wider than the
grids (I'm using ALP), both grids are set to grow horizontally and
vertically, and the splitter is not a pusher.

Splitter help

[John Baughman via 4D_Tech]

Never spitters working the first time. v16 R5 on a Mac.

I have 2 list boxes, 1 above the other. with a spitter in between. 

   What I need…

When I move the spitter, both list boxes grow. If I move it down, the 
upper grows and the lower shrinks and vice versa.

I have both list boxes set to Grow and the spitter set as a pusher. The upper 
list box grows, but the lower list box moves and stops everything as soon as it 
hits the bottom of the window. I have tried all combinations and cannot get it 
to work.

If I add another spitter just below the first, the bottom list box gets pushed 
off the window. I can live with this, but…

Any help appreciated.

John

Using a Web Area as a Data Entry Area

[Bob Miller via 4D_Tech]

Hi Everyone,

I have a task that might be a good application for a 4D web area.  This 
would be my first use of this feature; normally I'd use Arealist or a 
Listbox to do this, but in this case the number of variables is high 
enough that a new approach might be warranted.

The problem: we have a number of workcenters that each have different data 
collection requirements when a product is made at that workcenter.  I have 
a table for each workcenter that includes data on what each data element 
is; the user can set up a workcenter and specify how many data elements 
are to be collected, what the name of each data element is, and what the 
data type (alpha or real) of each data element is.

The problem is creating a data entry area.  The area is supposed to look 
like a spreadsheet so that a user can enter multiple data points on a 
single screen and then click one button that behind the scenes will update 
multiple records.

I've created a simplistic screen shot at:
https://s13.postimg.org/hmj5o10fr/Web_Area_Mockup.jpg

Basically, the program flow for the data entry portion is:

> User selects the workcenter for which he needs to enter data

> The web form design is programmatically pulled together with the data 
from the workcenter setup file - this includes data about the type of 
data, the amount of data to be displayed, the enterability rules, etc. - 
and it pulls in the privileges of the user.  The form is then set up with 
the correct number of rows and columns, the data is put into the proper 
cells, and the enterability rules are applied.

> The user either enters new data or overtypes existing data as required
> The user submits the data (is this a 'Submit' button in the web area or 
a button on the form?)

> The program checks which data elements have been changed and updates the 
database accordingly

So my questions are:
> What are best practices for setting up an enterable HTML table that will 
be displayed in a web area? 

> Is there any callback possible when the user enters data in a cell in an 
HTML table in a web area?

> How does one pull the data from the form out of the web area so it can 
be used to update the database?

If anyone has any coaching tips or - this would be wonderful - an example 
I could poke at - I would be deeply grateful.  Beers on me at the Summit, 
for sure.

Thank you,

Re: Collections

[Jeff Grann via 4D_Tech]

Haven’t worked with them yet, but my understanding is that a collection is an 
ordered list of values of possibly varying types.  In 4D arrays, all of the 
values must be the same type.  In a 4D collection, you can use mixed types as 
the elements.

Example:

$MyCollection[0]:=“Hello”
$MyCollection[1]:=5
$MyCollection[2]:=$AnObject
$MyCollection[3]:=$AnArray
$MyCollection[4]:=True

Re: Collections

[Olivier Deschanels via 4D_Tech]

Hello,

Objects and Collections are really different.

A collection is not an object.

During the post-class of the next 4D Summit, for my side in French, or for the 
JPR side in English, we have the same slide with this sentence in red, bold, 80 
points 
Regards,

Olivier

I think i you use arrays you already use collections… I had from older versions 
object constructed with OB set array. To read the object after I used:
  case of
:(is object)
:(is array object)
  end case
Since v16r5 the second test din't work no more and I had to replace: "is 
collection". So in my understanding an object array was just a collection of 
same things. 

From here:

"Collection variables store JSON arrays."
