Is there a way to dynamically set the number of columns/range of a matrixctrl object

- without loosing whatever has been set in it before, besides when shortening it?

You could also use some sort of storage like [zl reg] if you want to keep the values and reset them in case number of cells increases to a point where you set values before.

Using a message, without scripting is no problem. "without loosing whatever has been set in it before, besides when shortening it?" You can't decrease the size of a matrixctrl and expect the same col/row numbers to map 1:1. For instance, if you fill the upper 8x8 left quadrant of a 16x16 matrixctrl object and then reduce its total size to 8x8, you will lose half your values by displacement. If you want to maintain absolute row/col address values you will need to save them and recall them. I'm sure you could use a coll, pattr, preset, etc.

Whatever you decide to do, here is a way to dynamically change the row, columns and cell range of a matrixctrl object without scripting.. but you still need to reference range-matching images in your search path.

Here's a way to store all of matrixctrl's settings in a jit.matrix, and recall them whenever the matrixctrl is resized by messages. I set the maximum size at 32x32, but you can modify it to suit your needs.
