Dear All,
I have updated two applications I had on the newcastle info server. These can
be 'ordered' as usual from the info server.
IconClock (as appearing in Micro User) displays a clock on the iconbar. Three
clockfaces are allowed (raised, lowered or border) and choice of twelve of
twenty four hour clocks. This is a module and so will start up every time the
desktop does. The fix is involved with people resetting the clock when the
computer is running. Because the program only updates the clock every minute a
null event is only requested every minute. The time when the null event is
first allowed to occur was set initially and the increased in multiplies 60
seconds. This meant that if the clock was set back 20 seconds then minute
change would always occur twenty seconds too late. I have fixed this by
'resynching' the clock every time a message is recieved.
TurboFontLister caches the fonts available for a particular font path. You set
the font path to the desired value and then read then run the program. This
will create a module in the current directory. When this is loaded any attempt
to read the font catalogue for the 'known' path will result in the results
being returned from memory as opposed to from the disc, which is obviously
much faster (even for a hard disc). If a font catalogue is attempted to be
read for another path the call is passed on to the font manager module.
Because of the way the module works it must be loaded after the font
manager module. It should be noted that loading the turbofontlister module
will set the variable Font$Path to the value it was when the module was
created. As an interesting point while writing this module I came upon an odd
fact. The Font Manager module recognises the SWI &400BF (or whatever is the
last swi in it's chunk) although this has no name. Even more weird is the fact
that Impression II calls it upon start up as I thought that it may have
been for dialogue between the printer drivers and the font manager.
Yours,
PMF
