I submitted a bug report several years ago about not being able to drag nested elements after dragging a parent.  I think Ivica may have fixed it in Pd-l2ork because I can drag the nested elements after moving the parent, so it's an issue in Pd-extended and Pd-vanilla.

I can click the nested scalars in Pd-l2ork, though if I move them too far upward I lose the ability to select them.  A scaling factor is probably off somewhere in the monstrosity of code that controls this stuff.

is it possible to click/drag all nested elements only in pd-l2ork? Or you mean move the whole nested array upwards/downwards? The latter I can do as well, the "top layer" was always accessible.

The selection problem is there when scalars are positioned outside of a GOP. Although this isn't the case here, don't know if there's a connection between both.

But even if it worked properly, your interface will be limited by the automated, inflexible logic that only registers a click in the 10x10 rectangle enclosing the origin of the drawing instruction.

so it seems that nested elements "below the surface" are unreachable under this gui? is it an issue with pd, tcl/tk, or both?

Assuming that this field is further developed, I wanted to leave a question that might (?) be relevant:

- when drawing arrays with encapsulated arrays, it's not possible to click-and-drag to change the array contents in the same way it can be done with normal (single-layered) arrays. Or, to click and type numerical values.

As a test you can have this patch from my data-structures workshop:

- open [pd graphic]

- you can click/drag the base array in the green line, but you can click/drag the arrays inside it

- to change these arrays one must go to [pd encapsulated-array], and select the elements through the program

I don't know if this is directly related with "multi-dim arrays", but I thought about warning about this. I haven't seen encapsulated arrays in any other patches, so I don't know if many people are aware of this.

Best,

How do you do multi-dim arrays in c where each row can have a different number of columns?

In Pd I would do this:
[struct foo array a data]

and:

[struct data symbol svg_drawing_command array a the_data]

and finally:

[struct the_data float datum]

In c I've done a character array, an int telling me how big the character array is, an array for the numbers (actually a t_fielddesc array so they are settable per instance), and an int array to tell how many numbers per command.  So if the command is "M 10 10 L 20 30 A 1 2 3 4 5 6 7", the char array stores "MLA" and the array of numbers has "10 10 20 30 1 2 3 4 5 6 7".

I'm sending path data to the gui using this, so I want it to be fast.  Is there a better way?
