(I'm only replying to this email because I happened to have just read it. I'm really replying to the thread in general.) So here's a sampling of the points I've seen raised in this thread: 1) Toggle buttons look just like command buttons when they're "off". 2) There's no visual indication of the mutual exclusivity of radio buttons. 3) There's no visual indication that labels for radio buttons and check buttons are also clickable. Point (1) is interesting, and I think should be pursued further. But points (2) and (3) just seem like we're hacking solutions to problems that don't exist. I'm using Clearlooks, the default theme in upstream Gnome. When I hover over the label of a radio button or check box, the entire clickable area prelights. As you mouse your way towards the box, you'll see the prelight and, hopefully, realize you can click. As for mutual exlusivity, is there real-world data suggesting that this is frequently a problem? Even if users don't immediately grok the round-means-select-one thing, can't they generally get it from context? And if they can't, will connecting the radio buttons with chains or sliders actually convey that? There could potentially be cases where there are multiple radio button groups, and it isn't immediately clear which buttons belong to which group. But if that case arises, I'm inclined to say that the developers just need to fix their interface, putting each group under a distinct heading. I don't want to be the luddite, but I worry that we're just adding visual noise to solve a problem that doesn't exist. -- Shaun _______________________________________________ Usability mailing list [email protected] http://mail.gnome.org/mailman/listinfo/usability
