Perhaps you’ve primarily used SVG to render fixed images, or if the images do 
change, the triggers come from events in 4D, not on the SVG area. In that case, 
you probably don’t notice much difference. But the SVG spec creates objects 
just like HTML does, and just like HTML, you can bind events and attributes to 
those objects, and can do some very useful interactive stuff

The 4D SVG component and the 4D language don’t have any direct way to apply 
events to individual objects in an SVG area. With Javascript, this is easy. It 
is object oriented. Each SVG object can contain its own event handlers and 
attribute data. Objects can inherit prototype traits. Objects can nest inside 
each other. The language is built for this stuff.

An example of the difference would be in an implementation of drag and drop in 
SVG. You can do it with 4D, but it takes quite a few lines of code. Its pretty 
awkward, especially if there are a lot of objects. The same problem in 
javascript is simple and elegant and fast.

Configure SSL Web Server on 4Dv15

[Andrea Angeli via 4D_Tech]

Hi,
It is the first time that I try to config https on 4D and I’m not able to it.
I generated the request from 4D and send the request to Godaddy in order to 
create the cert files. 
I got the cert files from GoDaddy.
Godaddy generated 2 files with extansion in .crt but the files are text files 
so I just change the extension from .cert to .pem.
I verify the files .pem using openssl and they are ok.
The file names are set in cert.pem and key.pem.
In the cert.pem file I append the second file that, I suppose is the 
intermediate file, it has 2 ——BEGIN CERTIFICATE—— ——END CERTIFICATE—— 
If I start 4D it gave me the alert: “The database cannot be published”.
I tried to put to files separately on cert.pem and the second intermediate.pem 
so I do not change any text inside the file but I got the same alert

Does any one know where I’m wrong?

Thanks in advance

Andrea

Well said. Also, I should have made the point more clearly that you can get
the scaling library from D3 _without_ the rest of D3. No need to buy the
whole pig if you just want a pork chop.

Re: SVG Scale

> SVG is a whole lot easier to manage in JavaScript.

> I'm wondering about modern myths …

Hey Ortwin, you may not have had the same experience as me, but I find JS
easier for dealing with SVG. Just having foreach is a help, at a start. And
D3 is lightyears ahead, if you want to get that far into the weeds. To be
fair, I can't comment on the component as I haven't used it. I started out
doing SVG by hand to learn about SVG itself, From there I tried automating
it with 4D (hard) and then moved right into D3 (amazing.) But from the
comments and limits I see people running into, yeah, if you're planning on
doing a lot of work with SVG where you need the *full* feature set of SVG,
head to JavaScript.

[Tom DeMeo via 4D_Tech]

Hi,

> you've got access to the D3 libraries. 

I would strongly concur with David Adams point that you want to manage SVG with 
javaScript instead of the 4D language. This is an object oriented scheme, and 
its pretty difficult to work with if you don’t have an object oriented language 
to work with it. The D3 libraries or some other library are important too, but 
the language itself is truly important.

This style is really just accepting a single hierarchical object of parameters. 
You can write code that defines attributes in objects in a lot of different 
ways in javaScript. I’d recommend to anyone that they spend some time 
considering a coding style that appeals to them and always try to do it the 
same way. The syntax the library’s examples shows you is not mandatory. Its 
just a javascript object, and as long as you respect the underlying 
architecture of that object, you can use whatever syntax you prefer. 


Regarding SVG scaling, I haven’t specifically used D3, but I’m sure it makes 
scaling issues easier. However, scaling in SVG is still something that requires 
you to think through the relationships of your objects. It isn’t magic, and it 
can’t guess what you have in mind.

Consider the scheme on a 4D form. In 4D, the form itself and the objects have 
sizing parameters (none/move/grow). Splitters can provide additional control. 
Its a nice, simple scheme. However, if you don’t bother to set these 
parameters, you don’t get the scaling you want.

A few years ago, I worked out an HTML layout scheme using a different 
javascript library, Raphael. I wrote a code library so that I could set 
move/grow parameters just like 4D provides in its forms, which I think is a 
pretty smart scheme. I haven’t done anything with it for quite a while, but I’m 
still hosting a demo, so you can check it out:

http://www.svglayout.com/svglayout/index.html 


When you get there, click on the SL widget in the upper right corner to 
activate the editor. You will see object outlines and handles and can drag 
objects around. You can also double click on an object to see the sizing and 
scaling attribute dialog. The whole site you see is built using an SVG based 
layout scheme. Traditional HTML layout strategies are not used.

Re: SVG Scale

[Ortwin Zillgen via 4D_Tech]

> SVG is a whole lot easier to manage in JavaScript.

I'm wondering about modern myths …

There is a wonderful component in every copy of 4D, which is called 4D SVG.

This is a gem of a component and makes working with SVGs in 4D so much easier. 
I see the diehards still trying to do the xml-plumbing themselves.

For my own convenience and sometimes to better understand how it's done I check 
the source of a 4D SVG-command

and then fix my code

Re: 4D v16.2 false record locks

[Alan Chan via 4D_Tech]

Hi Koen,

I think your case is very different and might be v16 issue as user was still on 
server list and you couldn't disconnet it.

The trigger issue (not actually an issue) I mentioned was the record was locked 
and the related user wasn't even on the server list.

But I don’t know how the user left the building…

Because I did not know this command exists. Thanks for pointing out. I look
it is available from 16R2, project is not there yet, but will create

RE: Form with Custom Grow Box

Hi Cannon,

Thanks for the reply, I am certainly going to try it!

Do you perhaps know if there is a way to open a Movable form dialog box without 
title bar?
Because I didn't find how to do that, I want to create the grow box on a Modal 
form dialog box

Or is the reason you know how to create a custom grow box exactly for this 
reason?
