Re: Further Unicode ...
Hi Richmond, The useUnicode property has nothing to to with transferring unicodeText from one field to another. The useUnicode property affects the charToNum and numToChar function *only* and as you have already noticed it doesn't do a very good job on higher-level unicode values. That's why I rarely use useUnicode and use binaryEncode/binaryDecode in a repeat loop most of the time. To transfer the unicodeText, you need to do this: on mouseUp put the unicodeText of fld fCOOKED into COOKED set the unicodeText of fld fT to COOKED end mouseUp This is pretty obvious, as the useUnicode property doesn't magically convert the value of COOKED from plain text to unicodeText. Changing data in a variable always takes at least another line, e.g. put uniEncode(COOKED) into COOKED, but that's taken care of by using the unicodeText property directly. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Use Color Converter to convert CMYK, RGB, RAL, XYZ, H.Lab and other colour spaces. http://www.color-converter.com We have time for new software development projects.

Re: Further Unicode ...
Try one of this: on mouseUp set unicodeText of fld fT to unicodeText of fld fCOOKED end mouseUp or on mouseUp put unicodeText of fld fCOOKED into COOKED put unicode COOKED into fld fT end mouseUp on mouseUp put unicodeText of fld fCOOKED into COOKED set unicodeText of fld fT to COOKED end mouseUp For me any of above is working with ACII single letters as well with Unicode strings.

There's nothing regular about regular expressions, and like so many things in computing they seem to have come about through a series of evolutionary steps which may well be characterized as accidents. But it's the cryptic nature of regex that makes it so useful, providing a uniquely compact way of handling a vast range of text parsing in ways that would take many dozens of lines of code to do by any other means. So whether we like regex or not, it's here to stay, useful and ubiquitous enough to be worth the learning curve. That said, being a very generalized subsystem it's often not the fastest in execution speed in spite of being fast to type. In many cases, writing a pull-parser or other offset-based function for a specific need will yield a much faster result than using regex. The downside of not using regex, though, is the time required to write such functions every time you need 'em. For performance-critical operations it's often well worth it, but for less critical routines regex may be the more productive option. -- Richard Gaskin Fourth World LiveCode training and consulting: http://www.fourthworld.com Webzine for LiveCode developers: http://www.LiveCodeJournal.com Follow me on Twitter: http://twitter.com/FourthWorldSys ___ 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: Dockable Panes
Dockable panes are a deep subject. I have a need for them in an upgrade on the horizon for one of the projects I manage, and thus far my explorations have been challenging at best. One of those challenges is deciding how to handle the empty space left over from a removed pane. Should it be split equally among neighboring panes, or is one of those panes more important so that it should fill that space? In the app I'm working one there are some circumstances where each option may be best, but for usability I should probably pick one and use it consistently. Another challenge is providing feedback to the user during the drag. In some systems the panes update in real time during the drag, but with a good many complex groups this can be too intensive to do in LiveCode. So at the moment I'm exploring proxies, outlines to indicate how the panes will be resized as the drag happens. But even that is not without its challenges, since outlines alone don't always adequately communicate which pane is being indicated. Then there's the question of how a given pane should be split when another is dropped into it. Near the edges the decision is usually clear, but if you drop toward the center it's not always straightforward to decide whether to split horizontally or vertically. At the moment I'm considering abandoning truly dockable panes altogether in favor of a set of preset pane layouts the user can select from a gallery. This is MUCH easier to code, and simpler for the user to be able to anticipate how it works. I'll probably get back to experimenting with dockable panes later on, and the whole thing is interesting enough to me that I wouldn't mind if you want to continue this discussion via email or phone. Drop me a note if you do. Who knows, we may be able to come up with an affordable method for this which lends itself to a generalized framework that can be used in a wide range of apps. PS: If you haven't seen Pencil it's quite inspiring for dockable panes: http://www.pencil-animation.org/ That app has one advantage mine doesn't, though: it maintains one main pane in the center, so the docking decisions are limited to what happens at the edges. Still, it's one of the smoothest configurable pane implementations I've seen, very enjoyable to play with. -- Richard Gaskin Fourth World LiveCode training and consulting: http://www.fourthworld.com Webzine for LiveCode developers: http://www.LiveCodeJournal.com Follow me on Twitter: http://twitter.com/FourthWorldSys ___ 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: Help with Regex (was Re: Switch, Case and wild-cards?)
I ran into a similar problem doing search and replace in word to clean up text from some data system destined for excel. My solution was often to replace a character or string I wanted to preserve with a placeholder, replace or remove what remains, then restore my placeholders with the original values. In situations like this, work with bigger strings first, and sometimes you need to work it end to beginning, especially if you are using a word or character counter to keep track of where you are.

Bob Sneidar IT Manager Calvary Chapel CM Sent from iPhone Well, I am doing perfectly alright with the pattern searching routine I worked out with Unicode; as long as one works out which pattern to search for first, second and so forth everything is comparatively straightforward. This does not involve placeholders, nor anything else as bizarre. Here's a text: | abcdGfEhijGkElmnopGqrstuEvwxfyz | and I know that I have to move 'E' forwards to before the letter that precedes it, I know that I have to move 'G' to after the letter it follows, and, I know that I have to replace 'f' with ''. Now as 'G' and 'E' sometimes occur as 'doublets', vis 'GkE' I know that they have to swap before worrying about single instances of either 'G' or 'E', and that, as 'f' sometimes occurs in relation to either 'G' or 'E', or both of them, I have to replace 'f' with '' after the other operations, otherwise they won't work. So: 1. swap 'G' and 'E' when they surround one character. 2. move 'E' forwards by 1 when it occurs in isolation, and make sure that precludes those 'E' chars that have already been swapped by rule #1. 3. Ditto for 'G'. 4. replace every instance of 'a' by ''. One of the ways of avoiding falling over the results of rule #1 while implementing #2 and #3 is to encode 'G' and 'E' in rule #1 as different symbols, say '%' and '@' after processing so that rules #2 and #3 don't pick them up (one can always have some rules #5 and #6 to replace '%' and '@' with 'G' and 'E' after running through rules #2, #3 and #4). Now the fun of the whole thing is that I have to do that sort of thing with texts that contain about 20 patterns of the swap X with Y type. Having worked out a way to do this in 2010 (and then being fairly stupid and forgetting the whole thing) with Unicode putting the whole thing into practise has nothing at all to do with the strengths or short-comings of Livecode, but the limitations of the human mind to get itself wrapped around the underlying logic needed to work out the correct sequence of transformations.

Re: Dockable Panes
Dick, Take a look at Codejocks ActiveX control: http://www.codejock.com/products/dockingpane/tour_3.asp?platform=com http://www.codejock.com/products/dockingpane/tour_3.asp?platform=com This web page shows an animation of the panes being moved and relocated into another position. This is what I'm talking about when a pane is moved. Notice the handle icons that are made visible when dragging begins. It's a placement icon to show where the pane can be dropped, and it previews the place of the pane with a transparent pane when the mouse moves over it. Dick - answering your question, pane #4 would occupy pane #2 and #4 area. Again, you can see this in the Codejock web page referenced above. Richard - I read your reply and looked at the pencil-animation web site (cool software). Each pane can be represented as a toolbox or contain information such as record detail, for example. Each pane has a header, which contains a title and buttons. Buttons can be to close/remove the pane, or have a drop-down menu for actions. The header is the dragging object. I will continue to prototype in LC until I have something to show. If I'm successful at uploading to RevOnline, I'll place it there for y'll to take a look at. - Regards, Mark Stuart -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Dockable-Panes-tp4658476p4658505.html Sent from the Revolution - User mailing list archive at Nabble.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
