I have avoided this by getting myself in the habit of moving stuff around with a shift-arrowkey rather than the mouse. It takes a second longer, but it's almost guaranteed to work (it also helps avoid that annoying problem you get when you paste something directly over what you just copied and you don't know which one you're grabbing with the mouse).

i'm sure this must have happened to everyone a couple of times:
you cut a section of a patch, and paste it into another patch or subpatch. the pasted contents overlay existing parts of the patch, and you go to move them with your mouse while they are still highlighted.
however, sometimes your mouse just doesn't hit a part of the highlighted pasted objects, and the highlight comes off, and you're left with a big tangled mess of objects and patch chords.
other than just 'being super careful', is there any way to avoid or fix this problem without moving each individual object by hand???
After checking out Frank Barknecht's ds slider example, I'm trying to build a ds bar-graph that behaves like the max multi-slider, where you can click-drag to change multiple values in one mouse-swoop. In the attached patch, you can click on the red "handle" and drag across the bars to change the elements of the arrays. But I can't figure out how to resize the "bars" without using a metro to get the y-value of the handles. Is there a simpler way to do this? I tried using only one struct for both "bar" and "handle" but couldn't figure out how to get the bottom of the bars to stay constant.
Thanks, Jonathan
Wow, didn't really look at the programming, but the sliders look great...

i understand your question, and unfortunately don't have the answer because datastructs are a bit foreign to me.
however...if you are going to use this structure for controlling audio or visual processes, then won't you need to constantly poll the y-values of the handles anyway?
I haven't put it to practical use yet. But if I weren't using arrays, I would just have a scalable rectangle, for example, and get the y-value from the outlet of the corresponding struct. When stretching the rectangle, it gives a "change" message plus a pointer to the object, so there's no need to poll.
But a struct won't output anything when moving an array element. If it did, then maybe it's as simple as using [tabwrite] to link to a table for audio processing.

After screwing around with ds for awhile, I figured out that if you scale a point on a polygon or curve in the opposite direction of the y-scale for the plot, you get an anchored point that doesn't move, as in the attached bargraph.pd. Same thing works for drawnumber.
When I tested this using Miller's 0.42-0test06, I noticed some new features for data structures:
- Clicking a ds graphical object in non-editmode outputs a "click" message, pointer, and y-value from the corresponding struct.
- Clicking a plotted array outputs a series of lists: one for each element of the array. These lists come out of the struct box for the ds defined as the element of that array-- "bar" in my example. However, I can't figure out what the pointer in this list is pointing at: I get an empty/stale pointer error if I try to use it for either of the ds I created.
I also made a little scrolling bar graph test to get some heavy use out of ds while dealing with sound. In barscroll.pd, traversing the array every 40ms works fine with about 30 elements (at least with the simple, gritty sounds I'm using), but with 200 both video and audio get chopped up considerably. Sluggish redrawing seems to affect all data structures, too-- even in other patches.
Finally, I noticed a few things that might be nice additions to ds, if they're possible and/or desirable:
- quantization by variable: y0(0:100)(10:110)(variable)
- jump-on-click flag
- vertical plot
- drawsymbol outputting +1 or -1 msg (& pointer) on change
- keyboard entry for drawsymbol (same as drawnumber)
- fonts/sizes for drawnumber/drawsymbol
- ability to change pixels per increment for drawnumber
- [drawinlet var x y]
- [drawoutlet var x y -onClick -onSelect etc.]
- individual elements of an array outputting a list to the struct when changed
- some way to define a selectable size for grobs that move in non-editmode
- constraints on drawnumber scrolling when scaled
- have drawnumber ignore non-numeric input (instead of jumping to zero)
I have no idea how to implement any of these, but I hope at least a few of them would be generally useful.

hi jonathan,
you can update he bars by making them part of the handles. i attached my version of your attempt.
