LiveCode Forums

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, when I close everything and open my project again the rTree control is totally unresponsive and it looks like none of the rTree information remained in my project. I tried including the rTree .livecode file, but that didn't work.

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 mainstack. That will make the engine a substack which belongs to the mainstack, making it part of your new project.
