Hi, not sure whether this belongs here.. but it is part of my docking windows so I hope I guessed OK for this Q: How do I set the size of the ContainerSplitter? currently in my project it appears to have a width/height (depending on orientation) of 4 and I want t set this to 0 (or 1 if that's the absolute minimum), but I cannot find a property that affects this. help appreciated!
