Although McCLIM is functionally almost complete, it’s a bit fragile if you don’t exactly play by the rules, and often the rules have to be guessed at or worked out from the source code. Also, I’ve had to work around the unsatisfactory appearance of some things, especially windows created by accept-values. I’ve done new implementations of all of the LKB accept-values calls by explicitly programming gadgets and callbacks.<div><br></div><div>As an example, I attach a screenshot of my select-file dialog. I've realised why select-file is missing from McCLIM - as of CLIM 2 it’s been removed from the standard!</div><div><br></div><div>Ann: so I can test it well, what problems have you had with file selection in Allegro? Are the problems in Windows or in Linux? Might they be caused by having lots of mounted network filesystems, unusual structures of symbolic links, or some of the weird varieties of Microsoft file system mounting (see <a href="https://sourceforge.net/p/sbcl/mailman/message/19520335/">https://sourceforge.net/p/sbcl/mailman/message/19520335/</a>)?</div><div><br></div><div>Apart from the amount of time I’ve spent, I’m pretty pleased with how it’s shaping up.</div><div><br></div><div>John</div><div><br> <br><div><div>On 7 Nov 2016, at 11:17, Ann Copestake <<a href="mailto:aac10@cl.cam.ac.uk">aac10@cl.cam.ac.uk</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"> <meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"> <div bgcolor="#FFFFFF" text="#000000"><p>sounds good - re 1 - file selection is barely working in Allegro right now anyway.  I'll be happy to do some testing if you like, just not this week ...<br> </p> it would be nice to fix that type bug but not exactly essential ... it's been there quite a few years, after all.<br> <br> All best,<br> <br> Ann<br> <br> <div class="moz-cite-prefix">On 07/11/2016 11:14, John Carroll wrote:<br> </div> <blockquote cite="mid:39A8AA9F-762D-4EA2-8AB5-575EE1840CCD@sussex.ac.uk" type="cite"> This is going so well that I think it’s going to end up as a viable new public version of the LKB for the average non-expert user.

Clozure CL and SBCL both have good Linux versions, so it might also be useful for the average Linux user. <div> <div><br> </div> <div>In total I’ve made around 50 minor edits to LKB code. The main reasons have been: <div><br> </div> <div>1. McCLIM does not (yet) implement all of the CLIM spec</div> <div>2.

In category 2, the most widespread problems are omission of explicit define-presentation-type declarations for presentation types, and an assumption that panes are created ‘eagerly’ - whereas McCLIM does this lazily when it actually displays the window (which seems to be allowed by the spec). There’s one issue in category 3 that currently has me stumped for a work-around (changing the colour of text before a redisplay) but I’m sure I’ll figure something out.</div> <div><br> </div> <div>So far I haven’t tried to go further than (load-system "lkb”), and haven’t looked at any non-graphics related code, e.g. in pvm, psql.</div> <div><br> </div> <div>John</div> <div><br> </div> <div>PS While I’m at it, should I fix the bug described at <a moz-do-not-send="true" href="http://moin.delph-in.net/LkbBugs">http://moin.delph-in.net/LkbBugs</a> ?
