Sorry, meant to say the pointer that results from the Object Get name is to the 
entity

Re: Object notation replacement for use of Self in a script — v18

[kculotta via 4D_Tech]

18.1

The pointer OBJECT Get name(Object current) is to the entity instead of the to 
the entity attribute.

The field is eg, MyEntity.MyName, but the pointer to the form object ends up 
being ->MyEntity

Yes, I'm using it, but it really seems like an artificial way to get an entity

I'll explore your example.

Is there a "Get edited text without having to type anything first" kind of 
function.  
Does an entry area have an Object that contains its type and contents?

Re: Object notation replacement for use of Self in a script — v18

[kculotta via 4D_Tech]

This example does not avoid having to carefully name form objects and
the form object must have "matching" variable and object names: variable 
entity.MyName with its object name of  "MyName"

// the object method
a_test (OBJECT Get name(Object current))

// a_Test
$ent:=OBJECT Get pointer(Object named;$1)->
$s:=$ent[$1]
ALERT($s)  // the value entered into the text area

No one mentioned WA OPEN URL and a web area, which I thought would have been as

When I did get a pdf to open in the web area, all pages were available.

Re: Where Are All The Steppers And Spinners?

[kculotta via 4D_Tech]

Just in case you did not see it, a Stepper and a Spinner are available in the 
Object Library of the "classic" mode.

Re: Remote working with 4D networks - what are people using ?

[kculotta via 4D_Tech]

I remember connecting a terminal to the serial port on Apple's Lisa, and 
running a second user.  We must have installed Unix or Xenix at the time.  
Aren't "terminal services" already a part of Unix (or macOS)?  I put that in 
quotes because, apart form being a terminal services user on occasion, I am not 
familiar with the workings of it.

Re: Use Named Selection Unexpectedly Loads First Record of Named Selection

An unloaded record can still be the current record.

ALL RECORDS([RecipeRec]) // has current record
LAST RECORD([RecipeRec]) // has current record
NEXT RECORD([RecipeRec]) // no current record

It works just as you described in v18 Mac too.
If you put NEXT RECORD after ALL RECORDS, that second record is later restored.

Listbox arrow navigation - line 1

[kculotta via 4D_Tech]

This code will make line1 of the listbox highlighted. Pressing the down arrow 
moves the highlight to row #2.
: (Form event code=On Load)
ARRAY TEXT(A1;5)
GOTO OBJECT(*;"ListBox")
LISTBOX SELECT ROW(*;"ListBox";1)

This code does the same thing, except pressing the down arrow the first time 
has no apparent effect.
Pressing it a second time moves the cursor down as expected.
(btw, first pressing the up arrow key highlights the last populated line)
An entity selection listbox has the same behavior.
ALL RECORDS([Client])
GOTO OBJECT(*;"ListBox")
LISTBOX SELECT ROW(*;"ListBox";1)
GOTO SELECTED RECORD([Client];1)

Adding the line "POST KEY(Down arrow key)" is one way to solve the problem for 
the user.
Is there a less tricky way to fix that first down arrow behavior?

Thanks,
Keith

Re: SVG_New_textArea OR SVG_New_tspan

I find textAreas easier to work with for those purposes.  The only drawback is 
that the textArea is not supported by some browsers.  I'll see some documents

efficiencies than the classic way.

The input and output forms, not so much the brain, are starting from scratch 
with ORDA.  The code in the example is in a text object sitting above an entity 
listbox on the form.  "Self" was changed to "Get Edited Text" so the listbox 
changes after each keystroke, and ended up with this:

Case of 
: (Form event code=On After Edit)
$text:=Get edited text
If ($text#"")
$obj:=New 
object("$wordList";$text;"$fieldName";"Name";"$tableName";"Client")
$ents:=ORDA_WordQuery ($obj) // returns an entity 
selection, match if field contains all @words@
If ($ents#Null)
ents:=$ents.r_Contracts
End if 
End if 
End case 
// The ents entity selection is Contracts.  $ents is a Client entity selection. 
 The text entry area expects a Client name.


ORDA handles the problems solved by SET AUTOMATIC RELATIONS in both the input 
and output forms really well.  It is also flexible in terms of writing generic 
code.  You are right about pointers not being useful when trying to point to 
parts of an Entity.  

Christian, 
in your example:
  $clients:=ds.Client.query("Name = :1";"@"+Self->+"@")
  $contracts:=$clients.Contracts
is ".Contracts" meant to be the Table's name or is it meant to be the Link's 
name?

Thanks, Keith - CDI

ORDA RELATE MANY SELECTION

[kculotta via 4D_Tech]

Hello,

RELATE MANY SELECTION is a convenient way to get a set of related many records.
Is there a more succinct or efficient ORDA method than the following to do the 
same thing?

  // get Contracts for a group of Clients
ARRAY TEXT($array;0)
C_COLLECTION($col)

$clients:=ds.Client.query("Name = :1";"@"+Self->+"@")  // get the clients
$col:=$clients.toCollection("PriKey")  // make a Collection of Client Primary 
Keys ("PriKey";"..Value..";"PriKey...)
COLLECTION TO ARRAY($col;$array;"PriKey")  // make it an array of Primary Keys
ARRAY TO COLLECTION($col;$array)  // back to a Collection of Text 
("..Value..";"..Value..")
EntSel:=ds.Contract.query("to_Client IN :1";$col)  // search in the Collection

Dot notation in entry forms

[kculotta via 4D_Tech]

In an entry form with entry fields like entity.Name, entity.Address, etc...
When the cursor is in a field like entity.Address
$name:=OBJECT Get name(Object current) gets the form object's name, eg 
"text_Address", 
but OBJECT Get pointer(Object named;$name) always returns a pointer to entity 
(->entity),
so you could not get the length of the text in the field using Length(OBJECT 
Get pointer(Object named;$name)->)

Is there another way to get the field's value? (v18 latest build)

Thanks,

Keith

Re: OBECT SET TABBABLE?

[kculotta via 4D_Tech]

Actually that done in this way
Case of 
: (Form event code=On Clicked)
OBJECT SET ENTERABLE(Self->;True)
HIGHLIGHT TEXT(*;OBJECT Get name(Object current);0;100)
: (FORM Event=On Losing Focus)
  // check if populated...
End case 
looks like a path there.

Thanks

OBECT SET TABBABLE?

[kculotta via 4D_Tech]

Is there a way to change the tabbable property of an object in an entry form 
using the language?
It seems like "OBECT SET..." addresses almost every other property.
I'd like to make a field tabbable if it is empty, and skip it when tabbing if 
it has a value (the easy way).

Thanks,

Re: Pop up form window (v17.6)

[kculotta via 4D_Tech]

When it says "outside the window", it's referring to the pop-up window itself, 
so you are seeing the correct behavior.

• The window cannot have a close box but is automatically closed and 
the "cancel" event is passed to the window when:
• a click occurs outside the window;
• the background window or the MDI (Multiple Document 
Interface) window is moved;
• the user clicks the Esc key.

Re: Option click close box

[kculotta via 4D_Tech]

All true what you said, with some observations (17.3):

If On Close Box is checked, an input window gets the event, but does not close. 
 An output window did close.
If not checked an input window will close, revealing the output window it was 
opened from (when DIALOG was called without OPEN WINDOW being called first).
The windows were created with "DIALOG(outputForm)".

I saw the application window close, but was able to option-command-E to get the 
Explorer.
