Table.setContentCallback -> What happened?

[Oli Ullmann]

Hello to all! :-)

Table.setContentCallback(var contentFunction) can be used to set a function to be executed when a point is added, removed or modified.

Is there a way to find out what exactly happened? So whether a point was added, removed or changed?

And which point has been changed?

Many thanks
Oli

@Oli-Ullmann maybe a broadcaster can do it

@d-healey
Good idea. I'll try that. Thanks! :-)

Hey David,

unfortunately I haven't found a way to know if a point has been added, removed or changed.

I do have some insight into the value with a “ComplexData” broadcaster, but I can't do anything with it.

Have a look at my snippet. If you uncomment column 22, you will see the value. I couldn't work with trace either. Perhaps you have another idea?

I have now solved it with a MouseCallback-Broadcaster. When I left-click I add a point (the console prints “Add”), when I right-click I remove a point (the console prints “Remove”). It's not perfect, but it should be sufficient for my purposes.

What else I noticed: in the ContentCallback function of the table there is the variable changedIndex. However, this always returns -1.

Maybe this is a bug?

@Oli-Ullmann said in Table.setContentCallback -> What happened?:

Maybe this is a bug?

Maybe, I'm not sure

@d-healey
Have you had a look at the value supplied by the broadcaster? I have reduced this snippet to this. Do you have any idea what this is, or how it can be put to good use?

You must add, edit or delete a point in the table so that the console prints the value.

@Oli-Ullmann That's a base64 string. It could be representing the path or the table. Either way I don't think it's particularly useful.

[Oli Ullmann]

@d-healey
That is interesting! Do you have any idea how I can print the value? Console.print(Engine.decodeBase64ValueTree(value)); does not work.

[d.healey]

@Oli-Ullmann It won't be a single value, it will either be a path that you can draw, or the table itself (more likely) which you can apply to another table to recreate the table you already have - not very useful.

@d-healey
I got it. Thank you! :-)
