LiveCode Forums

It looks like it could evolve into an app for tracing the evolution of any kind of sequential process – for example, creating an eLearning course or planning an intentional community. An interesting interactive text<->diagram tool called Proquis AllClear Flowcharter offers a highly intuitive system...

Figured it out. When I answered all three variables in one string I could see that pSeed had a trailing return. Apparently that didn't bother Livecode when I asked if pSeed was 6 or "6" but it did silently break when I tried to use pSeed to lookup an array. This is not the first time I've spent more...

This works too. I get the keys I'd expect.

So I've got a function where I passed in some parameters. I'm trying to put the contents of an array into a temp variable using three of the parameters to specify the array position. It seems like two of the three variables work, but one of them doesn't. function resourceRollup pDoc,pSeed,pDirection...

sturgis, thanks so much! I'm not sure how long it would have taken me to think of combining a wait and grab, but that set me on the right path and now it works correctly :) This is the final script. It hilites/unhilites and drags properly! on mousedown if the cHilited of me is empty then set the cHi...

I posted this in the open forum but didn't get any traction. I've got a text field that represents an object. I want to either click on it, hiliting it, or drag it, repositioning it. However, I keep getting mouseMove messages before mouseDown, regardless of the fact that the mouse isn't moving. This...

I've got a text field that represents an object. I want to either click on it, hiliting it, or drag it, repositioning it. However, I keep getting mouseMove messages before mouseDown, regardless of the fact that the mouse isn't moving. This is a script that sort of works. It's got a couple problems. ...

Anybody still in the Virginia/DC area?

Oh, yeah right. Here is the thing https://github.com/matthewmaier/platyvue

I started learning livecode so that I could build a prototype of an idea I have for documenting open source hardware projects. It's complicated enough that it requires a dedicated application. I've shown the idea to other people and they've liked it, but they don't work in livecode. So I'd like to s...

rTree is poorly documented so I'm going to start collecting information that I need to understand and work with rTree that I had to search for. I want to send a message to my main application's engine when the user expands a node, so I used the nodeExpanded handler in the rTree object's script. But ...

This fixed the problem for me. Open the mainstack that you want to use rTree in, then also open the rTree engine file. Drag the rTree object onto a card, which makes a copy of it. Then open the property inspector for the rTree engine and under "basic properties" use the pulldown to select your mains...

I feel like I must be missing something obvious, but I can't get rTree to work properly. I create a new mainstack, then open rTree, then drag the control onto my new mainstack. At that point it mostly works, except for a couple things I found like having to manually change the icon ids. However, whe...

Thanks, I found this little nugget of wisdom in that thread: the formattedHeight of char 1 to - 1 of field 1 means just the text whereas the formattedHeight of field 1 also includes (besides the text) margins, borderwidth and scrollbars. Man, there are so many properties, many with overlapping effec...

Yeah, that's clever. So the number of lines returns 0 if the field is empty. Neat.
