So it seems that apple hasn't got a yesnocancel dialog. How do they costraint the programmer to put "cancel" on the left ? Is it just a convention?
They constrain the programmer to put the buttons in the proper place by threatening him with slow and painful death at the hands of hordes of angry users who clicked the wrong button because they didn't bother to read the button labels because they knew it was supposed to be in that place... in other words, yes, it's just a convention. They do have a readymade Don't Save/Cancel/Save dialog. The button ordering issue applies to all kinds of dialogs, and I think it's important for an application to feel "right", so we will still need a general solution. I'm thinking of something like a "button box" widget that automatically places buttons. You'd say that you have one OK button, one Cancel button, and one button that doesn't fit in any of those two categories, and the library would place the buttons appropriately. Cheers, Wolfgang
