Anyone done a colour wheel/picker ?

IIRC Oldes did something, but don't know. if it's available.

back again.... fixed a bug where resize didn't work during filtering 
and incorrect amount of results when filtering and turning off sorting

graham: it seems the convention is so that when you have a group 
of faces that need to be resized (such as the scroller), you use 
a RESIZE function rather than just a variable.

the filter works on multiple strings and is case insensitive. the 
purpose is to let you very quickly search for things without resorting 
to regular expressions or wildcards, with as few keypunches as possible. 
try entering "shoe" first. then "shoe very". "shoevery" won't produce 
a result

Henrik, that makes sense.

Now, how to change the font size of the font used in an area widget 
?

area/font/size: newsize .. doesn't do it.

view layout [area font-size 20] works here.

yeah .. wasn't working for me.

set-font area '?? 20

no matter .. got it going.

new version 0.0.5 uploaded.

single selecting works now.
standard font made a bit smaller.

selecting requires the use of a new face called LIST-TEXT with a 
FEEL that allows for mouse over and single/double clicking in the 
list.
single-click action is stored as a block in LST-ACT
double-click action is stored as a block in DBL-LST-ACT

Demo can be found at http://hmkdesign.dk/rebol/list-view3.r

0.0.6 uploaded... minor bugfix to keep the selected persistent even 
when sorting and filtered.

0.0.7 uploaded...

This one is released under the BSD license.

Changes:
      New: Added /force refinement to UPDATE

      Fix: Fields are rendered now, when filtering with fewer results than 
      the size of the list view.
      New: List now can have an edge of any size.
      New: ALT-LST-ACT action for right click actions.
      New: If HDR-COLS is empty, the header is now not drawn.

is keyboard navigation coming?

viz. moving up/down the list.

I tried it, but there are problems with focusing. Keyboard nav, requires 
focusing on the right face, and when I try that, selecting goes haywire. 
It's the same with mousewheel. Suggestions are welcome.

unsort: please put this on the right-click. Cycling through unsorted 
isn't standard and doens't make sense.

filtering: how about doing it in real-time, while typing.

real-time filtering - in old days I remember it was Allen, who introduced 
such field style ...

Henrik - as for the focus - do you try to focus/hilite particular 
cell, or just a row?

Robert: I will look at right click unsorting.


Realtime filtering is really up to the field that provides the string 
and updates the list, not the list itself (more flexible that way). 
I've done it before, where realtime performance could be achieved 
with more than 30000 entries in the list, so it's not a problem to 
do.

pekr: I've tried focusing a single cell, and I can get key and mousewheel 
feedback, but selecting is ruined by it.

robert, BTW tri-state sorting can be turned off with the TRI-STATE-SORT 
variable. then it only switches between ascending and descending.

(but it's broken in 0.0.7!)

sorry for the wait... Version 0.0.8 uploaded

Changes:

      New: Functions to select next, previous, next page, previous page, 
      first and last. Uses FOLLOW.

      New: FOLLOW. Automatically follows the selected entry so it's always 
      in view. Requires FOLLOW? set to TRUE

      New: SCROLL-HERE. Scrolls automatically to the selected entry.
      Fix: Filter result was lost after resize.
      Fix: Sorting was lost after resize.
      Fix: Sorting indication is now persistent after resize.
      Fix: Dual state sorting was accidentally broken.
      New: Initial sorting can now be set before first view
      New: Right-click on header unsorts the list

Demo can be found at http://hmkdesign.dk/rebol/list-view3.r

forgot an entry:


New: can return a row as a block or an object from the selected row, 
using GET-ROW-HERE.

Version 0.0.9 uploaded

Changes:

      New: GET-BLOCK retrieved the selected data as a block. Only works 
      with shift for now under multi and multi-row.

      New: Using the shift key, you can select multiple cells in multi 
      and multi-row mode.

      New: Five different select modes now: Single, multi, row, multi-row 
      and column.

      Fix: SCROLL-HERE only works with select modes 'single and 'row

      Fix: FOLLOW didn't work when selecting a row and then sorting


The different select modes might be interesting for a future spreadsheet 
face.

Are the header names hard coded into the list-view ?

they can be changed with the HDR-COLS variable

how does your list cope with an empty list ?

I don't know yet, but I plan to just let it draw empty cells. It 
should do the same if you filter for something not in the list

what's the syntax for creating a two column empty list ?

you'd use (for now):

view layout [list-view with [in-cols: [a b]]]

The list uses some standard values that are not correct right now, 
but I'll move those values into the correct place soon. If you for 
example set HDR-COLS to [], the header won't be shown.


The idea is that you have IN-COLS, which is based on the data you 
have in DATA. It's just a block of any words to tell each column 
apart. Then you will have OUT-COLS, which are the columns shown in 
the list view. The ordering of OUT-COLS determines the order that 
the columns are displayed in. HDR-COLS is for now a separate block, 
but it will be combined with OUT-COLS later. This ordering mechanism 
doesn't work yet, but it'll come in very soon.

Example of intended functionality:


in-cols: [person-id age sex height weight name address city country 
phone]
out-cols: [name age city]

Then you could reorder:

out-cols: [age city name]


And after using UPDATE, the list would update on the fly. DATA is 
not manipulated at all.

0.0.10 uploaded.

Changes:

      Fix: Optimized updating when moving from filtered to unfiltered view

      Fix: Accidentally didn't filter on the original DATA, when doing 
      multiple filterings
      Fix: Better detection of when FLT-STRING has been changed
      Fix: SCROLL-HERE can handle empty lists now
      Fix: Crashed if DATA was empty

      Fix: Selecting rows that are empty, no longer causes a script crash

      Removed: Ctrl-key functionality, because it's too complex to handle 
      with the different modes right now

      Fix: GET-BLOCK caused error if Ctrl-key was used to select cells.
      New: Data manipulation functions:
        INSERT-ROW, INSERT-ROW-HERE, CHANGE-ROW, CHANGE-ROW-HERE,
        REMOVE-ROW, REMOVE-ROW-HERE, APPEND-ROW
        These only work in select-mode 'row

I tried this

list-view with [in-cols: [user time] data: []]

which doesn't work.

doesn't work how?

the existing hardware columns appear and not the new named ones, 
and they are added to the existing ones.

the existing hardcoded columns still appear.  Then a large gray box, 
and then the scoller.

hmm.. that's because the layout is still hardcoded. you'll need to 
define a new layout in LIST-VIEW/LST/SUBFACE for now

I think I'll work on that now

the layout is for one row and it must be horizontal. you should also 
use the LIST-TEXT widget.

example:

layout/tight [across space 0 list-text 100 list-text 50]


but.. when I get this done right, it shouldn't be necessary to define 
the layout

I guess I'd better wait as that didn't work either.

uploaded 0.0.11

Changes:

      New: Header can now be defined from the words in OUT-COLS or IN-COLS

      New: No longer need to manually create the subface for the list
      Fix: DATA was not properly initialized

      Fix: List was updated twice during all manipulation functions added 
      in 0.0.10

      New: Added /no-show refinement to FLT-LIST to speed up certain updates 
      that require setting the selected row before showing

oops... the example code has been commented out, but the example 
line at the bottom should be fairly easy to figure out :-)

hm... still a bug when initializing the header... hang on

there... new 0.0.11 uploaded

seems to work now
