Probable bug in the List() class?

[Keivan]

When I was trying to execute this example in the List class documentation, I have noticed some strange behavior. I just want to make sure this is a normal behavior.

When I select an Item in the A[0] class (for example Random[1]) Neuron prints

Code: Select all

item 2 selected in list of object A[0]

which is a normal behavior, but after that when I select an item from A[1] class (for example Random[9]) Neuron prints the dialog 2 times repeatedly.

Code: Select all

item 2 selected in list of object A[0]
item 4 selected in list of object A[1]
item 4 selected in list of object A[1]

I think it should be printed only one time. Is this OK?

Doesn't happen for me. I just get a single
item 4 selected in list of object A[1]

But I'm using the latest version of NEURON--got the development code yesterday and compiled it. So if there is a bug, maybe it was fixed. What version are you using--what is the actual detailed "release information" that appears in the first line that NEURON prints when you start it?

I'm usin VERSION 7.2 (480:154ad065edb0) 2010-11-10.

Same here. That makes the difference in results rather surprising. My bet is the problem lies elsewhere--maybe your mouse buttons aren't sufficiently "debounced," so the circuitry is detecting a double click when you intended a single click. Mouse buttons operate switches that are mechanical devices, and all mechanical devices can have slight variations in performance. I wonder if the symptom would go away if you changed the "mouse settings" (make them a bit slower?) or maybe just use a different mouse.

It's not a mouse ptoblem. I've tried another mouse.
My CYGwin is not uptodate. I will update it and try again.

1. I've updated my cygwin. but can't compile it in the new one. excuse me but I'm sick and tired of this compiling issues. I will come back to this when I have enough energy.

2. what is your operating system? I've tested this problem in windows 7 32 and 64 bit. with latest alpha (compiled myself with my old cygwin) and also with this downloaded version nrn-7.2.alpha-469+-setup . problem persists.

3. I've tried ps2 or usb mouse also a laptop touchpad. steel no chance to solve the problem.

There is no urgency for me about this problem. I just wanted to report the possible bug.

You are probably slightly moving the mouse when you press the button. Selection events are both mouse down and
mouse move (while the button is down). On my virtualbox mswin I see that the sensitivity to mouse movement is very
great. I should fix this so only movement from one item to another causes the action instead of repeated action calls
within a single item.

With regard to building under the latest cygwin, if your problem is in the configure part, I found that it is important to
export WANT_AUTOMAKE=1.11
(in order to avoid random use of aclocal v 1.4)

You are probably slightly moving the mouse when you press the button.

But this does not explain my experience. even when i use a touchpad button (there is no chance of mouse movement when I click) this problem persists.
This problem happens only when I switch from list A[0] to list A[1] (even not from A[1] to A[0]).

export WANT_AUTOMAKE=1.11

Thank you. your tip solved the compiling issue. except I steel receive this error

Code: Select all

Error in script "nrnsetup.nsi" on line 192 -- aborting creation process
make: *** [mswin] Error 1

.

unfortunately the latest build could not fix the problem.

within a single item.

Finally got around to it. That fix is committed.

I've tested the fix under win and linux. it works the way it should be.
Thanks. good job.

This is unnecessary with cygwin 1.7.7 (latest version as of Dec. 1 2010) which includes a more recent version of automake.
