AltME groups: search

now if area could scroll by hiliting by mouse, most "bugs" would 
be fixed for me :-) Well, not me, it was Bobik who reported it to 
me, as for me, being keyboard guy - I am ok with ctrl + A :-)

Can I use multiple level sort on a table?
If yes how?

For those who are not developers, Ashley offers a download on his 
site.

If that is too hard ... well, I think someone has a problem.

Note that the easiest way to grab the latest SVN build (without using 
any client s/w) is via a simple REBOL script like this:


 write %rebgui.r read http://trac.geekisp.com/rebgui/browser/rebgui.r?format=raw

 write %tour.r read http://trac.geekisp.com/rebgui/browser/tour.r?format=raw


%rebgui.r (the complete merged distribution sans %tour.r) is now 
regenerated and uploaded every build.

Pekr,Graham,Henrik,Ashley, all of you,


Thanks for your help and interest. Everything is sooo new and there 
is a lot of it.

I am to "new" to help with the development part, however I can play 
and test.
Just want to make sure I use the "latest and greatest" 

I used to download from Ashley's site until I realized that I'm 2-3 
build behind.


I will RebolAutomize thinhs as I go and hopefully catch up with you.

Best regards
A newly Rebolized
Peter

Any of you gurus feels a need for a multi-level-sort-table ?
I  need one and hopefully I'm not alone ! 


I have a lot of data with a lot of same values in some columns, no 
simple sort will do what I need.

For right now a simple hard coded: first by Col1, than by Col2 and 
so forth will do.
A more elegant and flexible [sort-definition] can follow later.
Cheers

post your code

 ... I suspect it was as simple as adding a fiew widget names into 
 behaviors/tabbable via request-ui

posts an improvement leading to 3x speed increase
 ... where?

the first 'sort in your train function consume a lot of time

And a good collection of bin files would be located at?

just take a book well writed

take a classic

use books.google.com to find a good one

? It's less than a dozen lines of code!

steeve: don't forget, that the 1s difference in TRAIN speed does 
not actually matter, since it is just a dictionary preparation. What 
matters is the speed of the CORRECT function

Soundex is a language-specific algorithm, unfortunately

Looking at the new algorithm again, a lot of effort goes into weighting 
word use (the values block) which in turn is only used in one place 
... to determine the "best" candidate replacement. Given that a spell-checker 
just needs to return a sorted candidate list and the remainder of 
the algorithm handles this quite well, I'd be quite happy with a 
cut-down version that excludes the whole dict/values logic. That 
way I could use the existing dictionary files I have sourced (sans 
soundex codes).

So, to create a specialized dictionary, you can train it on eg. a 
medical text ?

I suppose medical text can contain a lot of latin words e.g.

Isn't that just look up and highlight...quite a bit easier/faster 
than offering corrections?

how easy it would be to do real time spell checking

 ... with a cut-down version of Ladislav's code (mainly limiting edits 
 to one char distance) speed is no longer an issue. I'm looking at 
 using draw to red underline all spelling errors in a text face and 
 then only popping up the spellcheck box on right-clicking a misspelled 
 word.


Problem is synchronizing red underlines with scrolling. R3's rich 
text support would make this trivia [by comparison] to implement.

The source code for area is here:

	http://trac.geekisp.com/rebgui/browser/widgets/area.r?format=raw

feel free to propose a solution.

or define a dialect for this purpose

the issue is not to create synchronisation but to have a good interface

process-keystrokes has been inlined into the display function. This 
fixes those errors where typing while the focus is on a button placed 
the characters into the previous field/area with focus.

Are these global in nature or specific to a display?

I have one password entry screen, then a status window, and then 
before the main window pops up, I get this error.

Is that a critical widget for you?

chart, 
drop-tree, 
grid & 
input-grid need a bit of work to get 
them working again with Beta 2.

Not a bad idea. How do you specify them (i.e. if not via a display 
refinement then where/how)?

F1 - F12? Do you have a sample of the code you've had to add back?

BTW, in chat.r, in a multi line text message, the blue divider cuts 
across the first line of text

If there is a lot of text, it won't display all the text in a message

So a 'set-message-text accessor?

I think it's nice to have an addition column for a message id.

Otherwise , if you try and refer to a particular message .. you can't.. 
except by pointing to a datestamp which may be different depending 
upon which time zone you're in.

I think with Altme, each message is followed by a font block etc.

so, each colum of data is then followed by a block that specifies 
the font, background etc.

Which might be a bit of overkill ...

Remember we are in a public group. You may want to take this private?

I basically wrapped a gui around other peoples' code :)

spellchecker is a must though :(

Although not ideal, you can always force a spellcheck with:

	...
	button "Submit" [
		request-spellcheck my-area
		...
	]

But check-as-you-go is where it needs to be.

and in a chat screen, you don't normally need to scroll the text 
in the reply area ..

How do you make a display stay on top without making it modal ?

Ok. I added a /options to display previously ...

I've had a search on the internet and can't find the dbase template 
syntax.

I have the Ashton Tate Advanced Programmer's guide which describes 
it, but I'll have to find a scanner and scan the pages in.

Build 78 uploaded to SVN. Includes the following additions:

1) New chat widget

	chat data ["Bob" none "Comment." yello 1-May-2007/10:00:00

2) New on-fkey handlers

	ctx-rebgui/on-fkey/f3: make function! [face] [...]


3) Soundex spellcheck logic replaced with new algorithm as discussed 
above


4) New, smaller, dictionaries (sans soundex codes) to be uploaded 
within the next few days

5) request-font enhanced (now has multiple refinements)

6) %tour.r updated


Note that the chat widget has a known display problem when it appears 
on a tab or is resized. The fix, adding a 'show in its feel/resize, 
appears to eat other widgets resize events. Not sure if this is a 
REBOL/View bug or not. Anyone who knows of a fix please speak up!

chart, 
drop-tree, 
grid & 
input-grid need a bit of work to get 
them working again with Beta 2.

Ok, we take a look at them.

Off the top of my head these are some of the things needed to be 
done:


1) Code a rebind func where applicable to handle dynamic UI changes 
(e.g. color)

2) Assign a string! to 'tip so my audo-doc system can pick it up 
(look at table.r for an example)
3) remove redundant ctx-rebgui/ qualifiers
4) check for global namespace pollution

5) Avoid having the widget dependent upon %rebgui-edit.r hard-coded 
widget handling code ... I've removed all the widget specific stuff 
(apart from button) ... If the widget *really* requires other changes 
then we need to talk and find a way of making such changes "generic"

6) References to 'action, 'alt-action, 'dbl-action need to be changed 
to use the new action object (e.g. action/on-click, action/on-alt-click, 
action/on-dbl-click)

7) Use (and possible extension) of the standard RebGUI UI objects: 
colors, sizes, behaviors & effects

8) Use (and possible extension) of the standard widgets objects: 
default-*

9) Removal of accessors/options that are unlikely to be used (.e. 
KISS principle)

That's probably enough to start with. ;)

Has the layout engine changed?  I'm using some custom widgets derived 
from text and field ( just preset sizes, and content ), and now when 
I display them, there is a large vertical space following 'return 
to the next widget.  This is only in beta2

Minor bug fixes and enhancements. Two related specifically to 'at 
and 'after (the later now always triggers a newline). Also have a 
look at:

	http://www.dobeash.com/RebGUI/user-guide.html#section-4.2
	http://www.dobeash.com/RebGUI/user-guide.html#section-4.3

which provide easy ways of making small changes/variations.


Of course it's quite possible you've hit a bug in the layout logic, 
can you reproduce the layout problem just using the box widget?

Is the chat error on initialization or when you try to add a message?

I've got a widget named 'outcome defined as 


outcome: make text [
	size: 0x5
]

there is a large vertical gap ( twice normal ? ) between the two 
visible widgets

Ashley, would you provide a working example of using the function 
keys ?  I'm having difficulty getting it working.

A merge of my changes with your latest

checking out a new version now

BTW, would it be okay to add caret support to spinner so that we 
can change a single character?

text (derived from label) is trying to protect you from:


 text 10 "A really long bit of text that should wrap even though I 
 didn't specify 10x-1"


but the problem is that if you specify 10x5 then it should honor 
that regardless of whether the text fits or not. The solution, I 
think, is to change the default size from -1x5 to -1x-1 but ensure 
that size/y is always a min of sizes/line.

I get a red line, which is deeper than specified

I'm using these hidden widgets to controll the low, high range of 
acceptable values in a widget, and to provide them with database 
field names

It allows a user to define a template like this:


label "Tender joint count? (0-28)" outcome "tender28" ifield  low-range 
"0" hi-range "28" return

so, outcome refers to the database field, and the user has integer 
field for the data, with a low range of  0, and a high range of 28

I guess I could use a custom widget and use options instead

or a spinner?

you have to highlight a spinner and type over it

Does a spinner allow blank field to start off with ?  Trying to avoid 
users accepting default values

Not at the moment. Should it? And if so, should it let them leave 
the widget without entering a value?

Well, I don't want to present a template with prefilled values

show?: false *should* work, haven't tracked down why not yet. Also, 
if you're going to be placing "hidden" widgets consider using box 
with a 0x0 size. This involved less processing and lets you use the 
data facet without having to "hide" the widget per sa. e.g.

	box 0x0 data "Text"

does what you want.

in 'current-word, add a check for series? str

A list of your changes would be good, might help to nail the remaining 
problems.

I've also got a sparker widget

A sparkline is a graphic intense object of word size

Probably not something that will ever be part of the base release, 
but feel free to check it in to SVN and add an entry to WidgetList. 
The pie-chart widget and Robert's chart widget probably fall into 
the same category. I'll eventually figure out a good way of providing 
a base + optional widgets download facility. What I really want is 
a checklist of widgets to download which dynamically builds a tailored 
%rebgui.r ... sort of a "would you like fries with that" type facility.

have a file named custom-widgets.r ??

For you edit-text patch, where do you place the attempt? (caret is 
handled in quite a view places there).

I've wrapped both in a gui-error/continue test which will write out 
diagnostic information to %error.txt but ignore the error.

Hmm.  I'm stuck in a edit-list .. can't tab out of it

what a life .. trapped in an edit-list!

and I did a show-focus to get to the edit-list

Ashley, View system has broken highlighting and caret positioning 
with center and right aligned text. It's been a problem for a long 
time.

Ah, because they don't get keyboard focus like area and field do. 
The fact that they are not tabbable [yet] is a separate issue.

I'm getting a 5 second delay on using the "close" button in the spell 
checker, or on the final "add".  I wonder if it's better to close 
the spell checker window down first and then do the file maintenance.

Sometimes you need to disable buttons etc, until an action has been 
completed.  Rather than redefining the action of the face, how about 
a putting a flag that signifies whether the action is active or not?

in request-spellcheck.r, what does this line do?

	;	do we have a string with > 1 char?
	any [not string? face/text 2 > length? face/text] [exit]

Checks that face/text is in fact a string and has a length greater 
than one char. We don't really want to spellcheck an empty string 
or one with a single character in it. Why, is it causing a problem?

getting a 5 second delay
 Got it. Hard to believe, but:

	write file form sort unique dict

is about a hundred times slower than:

	write file form dict


Sorting isn't so bad, but unique absolutely grinds it to a halt. 
Timings are:

parse		00:00.2
plus sort	00:00.8
plus unique	00:05

Doh! Thanks, that's now two errors I need to fix in spellcheck. Will 
upload fix in a few minutes.

Uploaded build#82 with above changes. Note also that the request-spellcheck 
function now has a /anagram refinement (don't ask).

Do you have a utility for us to build our own dictionaries?  Or is 
it just a collection of unique words?

The dictionary files are just a collection of sorted unique space 
separated words (all on one line, no carriage returns). I extracted 
them from the latest Abiword dictionary files. No utility as such, 
but the trick to generating them in REBOL is to get a block of strings 
then do a:

	write %my-dict.dat form sort unique my-block-of-strings


As for the button disabling question, I thought it was specifically 
related to the spellcheck taking 5 seconds. But, more generally, 
I'm against that type of thing. Far better to pop up an alert or 
progress bar for actions that will take time. Pressing a button should 
provide *immediate* feedback or results.

Ok, how about ghosting a button then?

Button and many other widgets have an 'info option already. Any solution 
to disable a widget dynamically would have to be generic and done 
via functions like:

	set-disable
	set-enable


On a related note, I'm thinking a request-progress function might 
be handy. Would have the following format:

	request-progress 10000 [foreach f read %. [...]]
	request-progress/cancel 10000 [foreach f read %. [...]] [...]


Advantage would be that it is modal and provides useful feedback. 
The /cancel block provides a "cleanup" routine if the window is closed 
the cancel button is pressed. Without the refinement no window close 
button would be present and no cancel button. Useful?

A progress function would be useful .. but less useful for me, because 
modal windows can disrupt BEER async communications

All the request-* functions are modal.

(length? word) < 2

 ... I think that was guarding against the empty string case as well. 
 But can be expressed better as "2 > length? word" anyway. Or just 
 drop the condition entirely. After all, "a" is a valid "word" "z" 
 is not.
