I have a standard-type menubar with standard pulldowns and so on. I want to relabel a couple of the operations on one of the menus depending on the application state. I know that sounds weird, but it's good ergonomics. These buttons do something that's easy to understand once you've done it, but hard to explain without saying very specifically what happens (in a context specific way) on top of the button. Problem is, after I change the XmNlabelString on the pushbutton, the associated XmNmnemonic is no longer underlined when the menu pulls down. This although the mnemonic character remains the first character in the changed label. So I got smart and went in and also reset the mnemonic when I changed the labelString. That didn't work so I also changed the XmNaccelerator and XmNacceleratorText, also without visible effect. HOWEVER, the mnemonic is not gone; it still works, it just isn't underlined any more. Went and cruised back and forth through the source (mostly in Label.c) but couldn't quite dope out what was supposed to happen. dbx says it calls _XmStringDrawMnemonic the appropriate number of times via the ReDisplay method... RTFM'ed quite a bit but no joy. I suspect this is probably a bug, not my problem, but... Any ideas? Tim Bray tbray@watsol.waterloo.edu
