Salesh, It's not common, but here is a use case on the desktop today: In an installer, you may have a tree view of components to select. Each item in the tree view is a tristate checkbox. If only some of the some items are checked, then the checkbox is shown as "mixed". - Aaron "Sailesh Panchang" <sailesh.panchang@deque.com> Sent by: wai-xtech-request@w3.org 04/14/2008 04:24 PM Please respond to <sailesh.panchang@deque.com> To Aaron M Leventhal/Cambridge/IBM@IBMUS, <wai-xtech@w3.org> cc Subject RE: Style guide: tristatecheckbox I question the concept of a partially checked checkbox. Checkbox and radio buttons are meant to hold just the 2 boolean values: yes or no. If one can have a 3 state checkbox (to correspond to Yes, No, Not sure), then why not a 5 state checkbox (that corresponds with something like Strongly agree, Agree, Not decided, Disagree, Strongly disagree)?

If the item is partially checked, space rotates through checked, unchecked and then partially checked again. However, the first bullet says if it's not checked that space checks it! Is the implementation supposed to have 2 different code paths for unchecked checkboxes depending on whether it was originally partially checked? - Aaron Three State Check Box If not checked, space checks the check box If checked, space unchecks the check box If partially checked, space will rotate through checked, unchecked, and partially checked states.
