Exactly. When I said “adding nodes,” I was talking about potentially adding both branches and leaves. My sample code was a small section of a larger one with more branches. > I don't see anywhere in the documentation where ADDBRANCH-1 is a valid term, Me neither, which is why I couldn't figure out why my flattree was a blank until I started this thread and was told about it by others. I tried looking for sample code, but the flattree was only in C, not Lua. Looking at the documentation now, I found a mention in iupflattree > attributes > hierarchy: "ADDLEAFid (write only): Adds a new leaf after the reference node, where id is the reference node identifier. Use id=-1 to add before the first node." Then it says that ADDBRANCHid works like ADDLEAFid, but I didn't make the connection that to solve my problem, I had to create a branch to serve as the first root, and to do that, use ADDBRANCH-1. I think a note that explicitly says this in the documentation would be helpful. Another thing I didn't realize right away was that the root node's id is 0 and not -1. You can find the earlier emails discussing it here: https://sourceforge.net/p/iup/mailman/iup-users/thread/28CE84F4-E49B-4EB7-9E3F-307725A9AB4A%40hxcore.ol/#msg37390775 By the way, does anyone know what's wrong with my emails when they get reposted to SourceForge? Do they come to other people's inboxes looking that horrible with code I didn't add? If not, I sent a support ticket and can hopefully get that sorted out. > I think the focus node should be the root node I believe the focus node is whatever is currently selected. _______________________________________________ Iup-users mailing list Iup-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/iup-users
