The neat thing is, it actually works properly (and on all platforms).
Hi Karl, Yes - all true, or at least about the title bar. I've just checked it in Linux. The problem appears to be that they're using a window for CHOOSE and on some platforms a window's border can't be got rid off. The following in Windows gives you a borderless layout... view/options layout [button "Close" [unview]] [no-border no-title] but not in Linux. What's more, on Amiga the NO-TITLE isn't needed to get rid of the border, but it is in Windows. (Though Amiga's depricated with regards to Amiga, at least at the moment, so...:) So windows' borders are a real problem for cross-platform apps in REBOL, never mind attempting to create popups. The real question I guess is what platforms RT plans to support with regards to View in the long-term. Will they go back to supporting all the platforms they started out supporting if resources ever permit them to again, or just stick with four or so of the main ones? As a limited number would perhaps allow them to do more as well as reaching a higher level of cross-platform compatibility. In the meantime though, it looks like we'd be best to stick to menus within a window... ): All that said, I'm still very impressed at the level of cross-platform compatibility View does achieve. -- Carl Read
