Fwd: Quantum tunneling in LiveCode
The issue of a background group being in two places at once is not quite clarified. Getting back to the script sequence below, when there is a mouseUp handler in a background group, the message, on clicking on the grouped button goes from: button -- group -- card -- stack When clicking on the card the message goes from: card -- group -- stack In effect the group acts on both sides of the card depending on where you click. So is mistaken to think that as soon as a background group is formed it mysteriously picks up and moves from one side of the card to the other (spreading out as it does so). It in effect remains on both sides, as seen by the message sequence when clicking on the button. I think the practicality of this discussion is in the situation where one wants, say, a cluster of buttons to appear on all cards in a stack, so one makes the button cluster a background group. If the background group has a mouseUp handler, its script will confusingly be enacted not only when clicking on the buttons but also wherever one clicks on the card. I think the bottom line is to be cautious about putting mouseUp scripts in background groups, or to put a disclaimer in the group at the beginning of the group handler the line (as mentioned in the User Manual (pg 131, 5.3.9): if the owner of the target is not me then pass mouseUp Stephen Goldberg www.medmaster.net -Original Message- From: stgoldberg stgoldb...@aol.com To: use-livecode use-livecode@lists.runrev.com Sent: Mon, Mar 2, 2015 4:07 pm Subject: Quantum tunneling in LiveCode In quantum mechanics something can be in more than one place at once. A paradox of sorts seems to occur in the message chain with groups in LiveCode. Try this: 1. Place a button on a card. 2. Make the button a group. Set the group's backgroundBehavior to true. 3. Place the following script in the button: on mouseUp answer I am a button pass mouseUp end mouseUp 4. Place the following script in the group: on mouseUp answer I am a strange group pass mouseUp end mouseUp 5. On the card script write: on mouseUp answer I am a card pass mouseUp end mouseUp 6. In the stack script write: on mouseUp answer I am a stack end mouseUp 7. Now click on the button. You get the sequence: I am a button -- I am a strange group -- I am a card -- I am a stack 8. Now click on the card. You get: I am a card -- I am a strange group -- I am a stack Where is the strange group, before or after the card?

Perhaps my Dell model thinks it can support multiple batteries (maybe counting the onboard clock battery? Seems unlikely). Once we discover the battery numbering scheme, parsing the byte stream at that location will be trivial. In fact, the articles I've found suggest that when that status element is present it contains just a single word, such as charging or discharging, shown in the example here: https://bbs.archlinux.org/viewtopic.php?id=133716 I'll see if I can get some time to look into this further this evening. -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Fwd: Quantum tunneling in LiveCode
While on the subject of out-of-the-normal message paths, I came across another one a couple of months ago. openControl messages are sent to the highest level group and then DOWN to any of it's child groups which seems the opposite of the normal message direction. It gets more interesting though. Let's say you have a group hierarchy like this: Group A GroupA.1 (child of groupA) GroupA.1.1 (child of groupA.1) If all these groups have openControl handlers, they fire in the following order GroupA GroupA.1 GroupA GroupA.1.1 GroupA.1 GroupA So not only do these messages go down to each child group but they also come back up again! In the above example, the openControl for GroupA is executed 3 times, GroupA.1 twice, and GroupA.1.1 just once. I submitted a bug report for this some time ago (#14091) and it's been stuck in Expert Review status for about 3 months. I don't know if it's a bug or not but it certainly seems like odd behavior and could certainly screw up whatever logic you have in an openControl handler. Pete On Tue, Mar 3, 2015 at 10:43 AM J.

According to the dictionary 'sharedBehavior' was introduced in LC 4.6.4, but it doesn't even appear in the current user guide at all, whereas 'backgroundBehavior' is mentioned multiple times in paragraphs about the message path and groups. There is no mention of 'sharedBehavior' in the LC Lessons on-line, but there is a tutorial covering 'backgroundBehavior'. The only places to learn about 'sharedBehavior' seems to be the Dictionary or when post like this show up on this list, or the 6 entries for 'sharedBehavior' in the forums. I appreciate that some things do fall through the cracks from time to time, but the cracks in LC documentation are growing wider with every new release. I am a huge LC fan, but to me this is probably the biggest failing of RR and we see it crop up over and over again, I think many of the questions on this list and the forums could be addressed with good quality documentation, and I'm sure that it would also reduce the stress on RR support, not to mention improving the LC user experience, especially for new LC users. Personally, I wish RR would use some of the crowdfunding money to employ a good technical writer to work alongside the software engineers, the current user guide (LC7.0.3) is revision 19 (2010.11.09), that's well over 4 years out-of-date, how many entries are really missing? Now I think I understand why RR dropped it from the LC Help menu for a while, but the fact that the users wanted it re-instating should tell them how important it really is. Just my 2¢.

I've read other cases online where folks find the same thing, but haven't found the definitive rule governing why. In my reading I also came across some laptop models (Toshiba came up a couple times) in which the battery firmware doesn't report its info in a standard way, making it more difficult for generalized utilities to obtain it. But frankly, if an OEM chooses to disregard published standards personally I can't see spending much time accommodating them, so I'm not too worried about such edge cases. Given all this, I would feel reasonably safe at this time with the following algorithm: First check BAT0/status If empty then check BAT1/status end if If both are empty there's probably no battery If a value is found then use it I've seen no mention of BAT2 or more, so I feel this should account for a reasonably useful range of contexts.

Re: [OT] Invalid host address
It sounds like their DNS might be hosed. Perhaps the user has manual assigned a DNS server instead of the local network assigning one for him. Perhaps that DNS server is inaccessible at certain locations. Some users like to manually set their DNS to Google’s DNS or OpenDNS.

revUnplacedGroupIDs has both false positives and negatives?
I know that it's undocumented, but has anyone looked seriously at revUnplacedGroupIDs? As I went hunting for crud, missing menus, and whathaveyou, As I stepped through (after blowing a foot off), I found that some of the ids covered by revUnplacedGroupIDs were, in fact, placed. In one case, it was most of the groups on a card. I also find it *not* consistently finding all of the actually unplaced groups, although this is much harder to track down. Has anyone else experimented with this? And, I suppose more importantly, can anyone reproduce it? -- Dr. Richard E. Hawkins, Esq.

Re: Power Status (was Re: Because LC can't do two things at once.)
Peter- Actually, BAT0 is a directory, so you want put url /sys/class/power_supply/BAT0/status into tStatus and what I see on my Thinkpad running linux Mint 17 is status returns one of three states: Unknown if the laptop is plugged into the AC adapter Discharging if running off the battery power Charging if it's (wait for it) charging the battery. If I remove the battery and run the laptop off AC power there is no BAT0 directory. -- Mark Wieder ahsoftw...@gmail.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Fwd: Quantum tunneling in LiveCode
Richard, Very nice explanation of this. I always wondered about the relationship between this properties.

In HC, there was always and only one background, which was placed below the card. In LC, there is no background object pe se, but instead employs groups which can be shared across cards. In LC we can have any number of groups, and they may even be nested. In LC, in the absence of an always-present background object, all objects always reside on the card. To maintain compatibility with HC, the backgroundBehavior was introduced in an attempt to account for those cases where the message handling order needed the background after the card, as it was in HC, rather than before the card as is natural in LC. In older versions of LC setting the backgroundBehavior was the only way to share groups among multiple cards, which sometimes caused problems for developers expecting the natural order of messages to be in play, reflecting the visual order in which all controls, even groups, are on top of the card. So a few versions back a new property was added: the sharedBehavior. When true this allows us to share a group across multiple cards, and when creating a new card any groups with their sharedBehavior set are automatically placed on new cards. It's related to the backgroundBehavior, but is not the same thing: When the backgroundBehavior is set, the sharedBehavior is also set. This should trigger the change you're describing, in which messages are handled by as group with the backgroundBehavior set occur after the card receives them. But the sharedBehavior can be set by itself, allowing sharing without altering LC's natural message order as reflected by what we see visually on screen: objects on top of the card get messages before the card does. So all that said, we might consider what you're seeing to be a bug. But personally, with more than a decade separating me from the last time I had a machine even capable of running HC, it's been so long since I've thought about the HC-style message order that I never rely on it. I was very glad when they introduced the sharedBehavior as a way of sharing groups while maintaining the natural, visible order of messages, and when I need messages to occur after the card I generally just put them in the stack or a library. But there are those who may need the older HC-style message order, and if so that's what the backgroundBehavior is supposed to provide. If you see a difference between LC and HC with message flow when the backgroundBehavior is set, it may be time to file a bug report. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Sorting Columns
An easy way is to extract the full dataset, perhaps with the dgData. This will give you a tab and return delimited list. Then you might sort by a function: sort yourData numeric by goodNumber(item columnOfInterest of each) where: function goodNumber var repeat for each char tChar in var if var is in 0123456789 then put tChar after temp end repeat return temp end goodNumber Craig Newman -Original Message- From: JB sund...@pacifier.com To: How to use LiveCode use-livecode@lists.runrev.com Sent: Tue, Mar 3, 2015 6:33 am Subject: Sorting Columns I have a data grid and one of the columns has numbers with commas included.
