mouse/menu control
by Kevin McGee 30 Oct '99

30 Oct '99

Hi, I just downloaded Squeak and am beginning to explore it. One quick newbie question: is there an easy way to change the default for pop-up menus? In other words, to reduce my carpal-tunnel strain, I would prefer not to have to hold the mouse key down to dispaly a menu -- rather, clicking once with mouse toggles between display of menu and removing display of menu. Cheers, k ______________________________________________ Kevin McGee kevin(a)kevinmcgee.com * www.kevinmcgee.com

One of my favorite things to do as an attorney when a client comes asking about hypertechnical ways to "get around" IP, is simply to suggest, "why don't you ask them if you can have permission to do that?" This isn't always the right advice, but it often is. Consent is the only 100% absolute defense in this business -- if you prove consent, you always, always win. The owner of a copyright can do what he wants, and if he is willing to give a license under the Squeak terms, we can incorporate it without having to deal with RMS, Peter or anyone. Note that there are presently pending cases where products are being withheld because of GNU licensing conflicts. Let's be careful. RMS designed GNU so that the world would be GNU only, and recent activity seems to suggest he meant it. I agree that GNU can be circumvented in a manner favorable to what we want to do (and the only thing we can do): distribute Squeak under the terms of the Squeak license, but someone ought to be able to say, "yes" to the straightforward question, and not an indirect basis for a legal argument, so we don't actually have to lawyer this thing to get to an answer.

Access to Squeak mail-list archives

Re: [UPDATES]
by Dwight Hughes 30 Oct '99

30 Oct '99

It would get a bit confusing if others sent [UPDATE] or [UPDATES] messages since one expects to be able to use the "update from server" mechanism in Squeak to retrieve any [UPDATES]. So, yes, it would be good to "reserve" this for SC. I think the primary message tags used in the Squeak list so far are: [BUG], [FIX], [ADDON], [GOODIE], [ANN], [ENH], and [UPDATES]; sometimes you will see [NEWBIE], [REQUEST] or [REQ], and [Q]. [ADDON] and [GOODIE] are pretty much equivalent - I prefer [GOODIE] for historical reasons. [ANN] is more general -- often applied to things like a new or updated port or VM or some such. -- Dwight Stephan Rudlof wrote: > > Dear Dwight, > > I thank you very much for your precise answers.
