Widget TurnImage89_v100
TurnImage is a pure LiveCode Builder widget, there is no essential script access and no use of JavaScript. The widgets lets you = turn an image horizontally or vertically with a 2D-perspective view, = switch from an image to a second image while turning or rotating. Thus it is essentially an animation tool for displaying LC objects. For example two groups of same size that make up the front and back of a turning "card". Just try the demo in the sample stack. The widget is fast enough to "turn" a video by grabbing frames from it. For this we need to use a browser widget to play the video (just play, nothing else) because the LC player object is essentially blocking. TurnImage is a "fat" widget that works with LC 8 and LC 9 identically and also in all LC editions, from community up to business. This sample stack includes buttons to install (or remove) the widget to/from both LC 8 and 9. And it containes several examples for scripting the widget's properties. Download it from "Sample Stacks" or http://livecodeshare.runrev.com/stack/929/ The widget is free for non-commercial use. For commercial use please give a (small) fee to the LC developer help fund. The source code (lcb-file) is not included. ___ 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

AW: Re: How to tell if a field is "closed"?
Thank you everyone especially Geoff and Mark. I ended up making some UI improvements, using a flag, and the focus tip from Mark so now the "Import" button is only enable when all fields are closed AND validated! I should have thought of most of this myself, but some days you have to write code when your brain would rather not. ___ 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: How to tell if a field is "closed"?
I think you had it right when you mentioned that you should redesign the interface. There are many threads, especially on the forum, debating the merits of live validation of user input as opposed to anything else at all. I always, always recommend never letting invalid data be typed or pasted, whatever, into a field where such data will break something down the road. Rewrite. I bet is not too onerous a task.

In your closeField handlers, if the field fails validation do: if then answer "Field failed validation" with "Oops - I'll correct it" or "Cancel" if it is "Cancel" then exit to top end if focus on me exit closeField end if Then in your import button do: on mouseUp focus on nothing if the selectedField is not empty then exit mouseUp end if answer "Go!" end mouseUp This should mean the import step won't run until a closeField handler has successfully finished.

Re: How to tell if a field is "closed"?
I'm sure someone else will come up with something better, but at the least, don't set a custom property for each field; instead, in the openField set one custom property for the card or group that the fields are in, something like "isOpen", with the long id of the open field; then empty that property on exitField. That way when you import you just have to check that one property, and if it contains a long id, validate that field.

RE: How to tell if a field is "closed"?
I think that you are on the right track. I would have a tPending variable with a true value that changes to false when the field is complete. "OnLeave" or "exitField". This variable would not allow any other task as long as the tPending variable is true.

weird video screenshot problem
Hello, I am experiencing a very weird problem, taking a screenshot from a video on Windows. Perhaps anybody has an idea where to look for? I have two programs, where I am playing the same mp4 videos. The user can make screenshots from the paused video and store them as JPGs/PNGs. If the user has the windows display settings text size at 100%, everything works fine in both programs. When setting the windows display text size to 125% or above, the quality of the screenshot in one of the both programs gets almost unusable. The image is corrupted by many bad pixels (red, black and lost pixels). The other program still shows a fine screenshot. My first idea was, that there must be a difference in the build of the standalones, so I tested the two stacks in the same LC 9.0.2 (and down to LC 8) IDE with the same result. I compared the two stacks and didn't found a relevant difference in displaying the video and taking the screenshot. Both codes are almost the same here. The relevant code looks like: set the alwaysBuffer of player "VideoPlayer" to false start player "VideoPlayer" stop player "VideoPlayer" export snapshot from rect (globalLoc(topLeft of player "VideoPlayer") , globalLoc(bottomRight of player "VideoPlayer")) to gScreenshot as PNG put gScreenshot into img "ScreenshotImg" Here you can download an example of the two screenshots in a pdf: http://www.kestner.de/material/screenshot-test.pdf Has anybody ever seen such a phenomenon? Any idea what could cause this issue in combination with the text size of > 100%? And for what difference I could look for in my two programs what could cause this issue in one of them?
