Re Module Desktop+
1.41 & earlier: No notes here.
1.42 Changed sprite dir code which uses 2 sprites to distinguish between
selected/not selected {rather than marking icon selected (which
inverts it) or not} to also invert text part of icon (as Filer+
does), by switching fore & back colours.
This makes it much clearer which icons are selected in a multiple
selection, or where the 2 sprites differ only slightly.
1.43 Slight mod. If sprite dir option code should have previously
encountered a filer dir icon already antialiased (by filer or
another patching app), selected & with its own sprite, when trying
to invert text part, it would have screwed up font handle & failed
to invert it.
Situation isn't thought likely to occur, so haven't corrected
failure to invert, but have put a stop on the font handle scrambling
part, so if this case should ever arise, will not crash/scramble
icon, but just fail to invert text part.
Could of course extend code to cope with the inversion, if thought
necessary.
Also, inclusion of a check during initialisation, that os is 3.10 or
greater (via Utility Module version number).
1.44 Slight improvements to error handling during init/fini - should not
now crash machine if any error occurs (eg if can't find font) -
previously, it didn't reverse actions such as claim swi vector,
register filter, or find font, but module still died, so in vector &
filter cases os subsequently tried to execute non existent code
(oops - sorry).
Also added warning (at head of source), about fancy text size going
wrong after mode change if another app has screwed font$path up so
that Resources:$.Fonts isn't scanned anymore.
1.45 Bug re filer icon drags going to outline (when should be solid)
fixed.
This has nothing to do with possible bug re task handles (which has
previously screwed up fancy filer text, & with wellsolid, filer icon
sprite drags). Recall, D+ records last selected icon in a given
filer window, for upto 4 windows, & forgets a recorded
window/sprite-name pair when it is deselected. Bug was due to
failure of D+ to forget a pair, if the deselection was due to
closure of the parent window, thus the 4 item list could become full
of pairs of long since deselected items, which D+ should but hadn't
forgotten. Thus there becomes no more room to remember new pairs,
for subsequent drags, hence bug.
Fix: preprocess Wimp_DeleteWindow SWIs - Compare window handle with
each of D+'s remembered handles, & for any match, reset (to -1),
that recorded handle.
1.46 For indirected sprite only icons, the sprite area is specified in
the icon data.
It seems FormEd will use a value of -1 for the wimp area, even
though PRM (& other progs) specifies/use +1. However, wimp does
correctly function when FormEd does this, so Desktop+ should behave
in a consistent manner.
Thus implement small change such that an indirected sprite only
icon, with area -1, will be treated as if the area given was +1.
1.47 Seems as though if sprite icon has area specified directly or via
window data, as non-wimp-area, then although wimp will look in that
area for sprite, if it fails to find it, it won't leave sprite
invisible, but instead first tries wimp area.
This allows a mix of user/wimp sprites of type indirected text &
sprite, on the one window (these would otherwise have to have the
same area, which would be taken from the window info).
I should have realised this a long time ago.
Desktop+ will check only in area specified in sprite or window data
as appropriate; if this fails it uses old outline drag.
It should behave as wimp does; ie if search fails, then try wimp
area. 1.47 fixes this.
1.48 It was recognised some time ago that DragASprite cannot handle 256
colour sprites, & a patch into the code which replaces drags over
sprite icons with solid drags, was added so that if the given sprite
is 256 colour then an old outline drag is done. However, a similar
patch was not applied to the separate section of code which deals
with filer icon drags.
Now it is not usual for file icons to be defined in 256 colour
modes; indeed the style guide specifies 4bpp modes; however since
RISC OS 3 allows 256 colour sprites in icons, it is possible that we
could encounter such a file icon.
Have implemented a suitable test which causes reversion to outline
drag if an 8bpp file sprite is encountered, in v 1.48.
Recall, if an 8bpp sprite is given to DragASprite, then if current
mode is 8bpp, drag works though colours are scrambled, however if
mode is not 8bpp, then drag fails to start; we get neither an error
report, nor reversion to an outline drag - the request to start a
drag is simply ignored. In the context of Desktop+ trying to solid
drag a filer icon, this would make it impossible to drag the file
out of a filer window.
NB For future reference, may consider adding another patch to
DragASprite (in same was as semi-transparent drags are done), which
checks if sprite is 8bpp, & if so, replaces it with a 4bpp version
based on the 8bpp one (either use the usual best colour mapping
possible, or use more complex processing incorporating error
diffusion). If do this, then will need to remove the 8bpp checks in
D+, so that it will pass these sprites on to DragASprite.
NB2 This modification to give v 1.48 was made after I made use of an
8bpp file icon - specifically, the Clares logo sphere, used as an
application icon for !Spheres, the app used to generate part of
Clares logo, for inclusion in Montage.
1.49 Directory sprites are now also used on the standard pinboard. This
does not include the secondary sprite used when a filer icon is
inverted (can't be done properly, i think - ie can't construct a
single icon st on selection sprite changes & text part inverts) - so
instead put up with using a single sprite & inverting it on
selection.
1.50 Special Multiple file sprite used when solid dragging a group of
files, on either pinboard, or in a filer window. !DirSprite now
contains a suitable sprite to use for this, however this may be
replaced - the sprite should be called multifile, & loaded into the
wimp area (ie *IconSprites a sprite file containing such a sprite).
Also, semi-trans code changed such that if sprite is 16 colour, mask
is perforated manually (rather than via SWI to alter every other
pixel's mask status). This is essential on an ARM2 machine when
dealing with large sprites such as a mode 27 version of 'multifile'
which can be around 114x113 pixels - thus 6441 pixels need altering,
& using the SWI call takes about 2 seconds. The new code cuts the
time such that delay is not noticeable.
Finally, a bug in the general solid app drag code was found & fixed.
Old code used ptr constraint when the box data required box
constraint. However, although DragASprite allows both forms, box
constraint doesn't work correctly (see below), thus had to add some
code to modify parent box st would give correct behaviour for ptr
constraint.
Re DragASprite problem, it seems that if you specify box constraint,
DAS calcs pos of sprite within initial box, & then uses the minimal
box bding the sprite, as the initial box, instead of the initial box
it was given.
This will give incorrect behaviour unless the initial box given to
DAS is an exact match to the sprite bounding box. Often this won't
be the case - eg for a text/sprite icon, programmer may pass the
icon bding box, which will be larger than just the sprite. I guess
this constitutes a bug in DAS, as I doubt this was the intent of the
SWI's specification.
Another change: Reduced multifile sprite to about half previous area
- it was placing too much of a strain on processor during drag, &
redraw was becoming too jerky.
1.51 Several mods concerned with relative position of sprite to ptr
during drag:
In single file drag from small-icon/full-info display, sprite is now
centred on ptr, rather than on original file icon in filer window.
In multi icon drag from filer or pinboard, multifile sprite is now
centred on ptr, rather than on original group of icons.
NB both these mods work by centering the initial drag box on the
pointer, which means (eg) when dropping files onto pinboard, they
will appear within this drag box (as before), but now centred on
pointer, rather than maintaining offset between pointer & the
original drag box enclosing source icons.
I think this often gives more natural behaviour than before, as well
as keeping pointer & multifile icon together during drag rather than
separated by large offset, however it takes a little getting used
to, & can be slightly confusing when dragging multi-selection from a
full-info display to pinboard.
1.52 Several mods re use with new filer etc (of which I of course have no
knowledge - just guessing what might turn out to be useful):
Options now default to 2_10001 - solid app drags & sprite dirs on;
fancy filer text, filer solid drags & semi-trans solid drags off.
Filer sprites 'directory<c1><c2>' & 'small_dir<c1><c2>' are replaced
by custom sprites if they exist, for any characters c1 & c2
(previously c1 had to be the null terminator).
If a solid drag comes directly from filer & sprite dirs D+ option is
on, then if appropriate, will change the choosen drag sprite to use
the custom sprite as displayed in the filer window.
1.53 a) � Serious bug from 1.52 fixed:
With sprite dirs & filer solid drags both on, ordinary
directory drags become invisible under RISC OS 3.10/3.11 etc.
This is due to the DAS patch corrupting data used by the Filer
patch (the initial drag box position).
Fixed this by making the two routines use disjoint buffers to
store their data.
b) � Very old sprite directories bug fixed:
A transient selection of a directory due to click of menu over
a directory in a viewer where all items are unselected, can
cause a missed PlotIcon when the menu is destroyed, if the
destruction results in a MenusDeleted message & the menu has
been moved to reveal the icon prior to deselection.
This PlotIcon wasn't caught as the wimp filter masked out
messages events. Fixed this by altering mask to allow these
events in filter.
c) � Augmentation:
Sprite directories option previously needed all sprites in
pairs (both a # type & a $ type).
Now, can cope with being given only a # type sprite.
In this case, on icon selection, icon will be inverted as
normal (rather than being swapped with the $ type, if it had
been present). This saves memory & time, should one choose not
to use the two sprite animation, but instead stick with the old
behaviour of filer selection by inversion.
d) � Additional feature:
Support is now given for modified file sprites independent of
file type.
Note, this is controlled by the sprite directories option,
which now switches both customised directories &
customised files on/off.
To customise a file sprite, give the file a name which ends in
an affix /<abc> (or \<abc>), where <abc> is any 3 legal file
name characters.
Note, in general use the affix /<abc> must be used as the '\'
character is not a legal file name character
{see iii) below for a reference to the \<abc> affix}.
Load sprites into the wimp pool, with the names file/<abc> &
small/<abc> analagous to typical file sprites file_xxx &
small_xxx, for file name affix /<abc> (use file\<abc> &
small\<abc> for affix \<abc>).
The new sprites will then be used to represent all files with
the given suffix, both in the filer & the pinboard,
irrespective of file type.
Important: this does not alter the file or its type & hence its
RunType is unchanged; only the file icon's
appearance is altered.
Note, if you use the filer display options 'full info' or
'small icons', you must supply a sprite small/<abc> (or
small\<abc>, as appropriate), otherwise the old file-type
dependent sprite will be used (unlike with the custom
directories option, where if you don't supply a small
sprite, the large one will be used at half scale).
Note, unlike the customised directory option, custom files do
not change when selected; they just invert, as for normal
file icons.
Possible uses:
i) � Give a visual distinction between various resource files
which don't need custom Run aliases, without need for
allocation of several file types from Acorn.
ii) � Distinguish between differing source filetypes amongst a
collection of squashed files.
iii) � Perhaps differentiate DOS files (I don't use a PC or the
PC emulator - is this idea a workable useful option?).
Note, support for the affix \<abc> has been made with
this use in mind.
Perhaps this use is made redundant by the *command
DOSMap. Any comments?
1.54 Re 1.53 d):
Have now removed support for a file name affix \<abc>. This is
believed to be redundant.
The affix /<abc> is adequate for all purposes.
