Re: number of columns in a table field

[Bill Marriott]

Can you imagine the outcry if Excel supported only 2000 rows? But the "real" 
limit is even lower when you consider the performance realities. Consider if 
you have a grid, 1000 rows of 20 columns, and you want to delete row 2 then 
you must somehow update 19,980 objects.

You could say, "Well, don't structure it that way. Use only the fields 
necessary for on-screen display." Unfortunately, once you are in the 
business of going into fields and setting them, Rev bogs down as well.

What I arrived at was using a single field for each column, but it still is 
not as fast as deleting a line from a single field.

Corrupted Images

[Bridger Maxwell]

Hey,
 I have been having troubles with a few of my stacks.  At random times
images that I have imported will just show up as a big rectangle of uniform
black and white pixels.  The only resemblance the image keeps is its
original size.  I think they have all been PNG images.  I would use a
different image type, but PNG is the best for transparency.  Has anyone had
this problem before?  It has happenend in both Revolution Dreamcard
2.5.1and Revolution Studio
2.7.

On Gentoo (with KDE), I get:

in my sys_info.txt

Under KDE it looks like you have trouble with FontsFolder, StartupItemsFolder, 
TrashFolder. 

I'm fairly sure the normal fonts location is: /usr/share/fonts/

My startup items folder is at: /home/rishi/.kde/Autostart/

My trash is at /home/rishi/Desktop/trash.desktop which is a shortcut with 
URL=trash:/  
I'm not sure how those KDE/Konqueror KIOslave URLs work in terms of file

Regarding the standalone module for discovering fundamental system path

Meaning of "language" names

[Dar Scott]

Several places in Revolution as in font names, htmlText, uniDecode(),  
and uniEncode() the word "language" is used to designate the  
character encoding.  The value for language is not the name of some  
standard, it seems, but is some other name, often the name of a  
natural language.  Presumably there is some map from the Revolution  
names to the character encoding standard.


Is that arbitrary, or based on some Internet standard such as an IANA  
standard or the MIME standard, or based on some Font standard?  How  
do I get from the Revolution names for character encodings to the  
standards?


Does the "language" in this context ever indicate anything other than  
character encoding to Revolution?

Richard,

exactly what I meant at the end of my above quoted post:


The needs are certainly different for all users, but in any case it
would be a valuable enhancement to Revolution to have improved

possibly with a DLL that would open the door to work with

Such enhancements would certainly attract new users and encourage
present Revolution users to experiment with image processing.

Hi from Paris,

I agree about Rev gagging on large JPEG files, and
coming up with a black rect.

It might be that Rev is gagging on the large JPEG.  Perhaps, this
works better with PNG.


I had to scale down many of my JPEG files with
GraphicConverter to get them visible in my stack.
If the JPEG is less than 500K, then display is almost
immediate. If it is over 2 megs, be prepared for a long
wait - and the dreaded black rect afterwards (Mac G4 733)!
2 meg colour photos from my Sony digital, scaled down
to less than a meg work beautifully. Strangely enough,
high volume Black & White photos seem prone to this
problem, although I haven't quite fathomed out the whys
and whens ! It seems as if most of my problems come
from scanned B & W photos (HP ScanJet 7400). I may
rescan these using a different quality. I also use a little
routine to scale the "too tall - too wide" photos into the
smaller wondow. This may not help either. I will try PNGs
when I get some time !

hmmm 3 X 3? ... too small. Does  it mean that any starting image must

3X3, of course, means the size of the matrix filter, you can use Chipp's 
DLL for any image size and different rects (as far as my experiments 
went). My own scripted filters are adapted to an image size of 640X480, 
but that could be easily changed; however, the larger the image, the 
more processing time is needed - execution time for most of the no-dll 
640X480 filters is between 1 and 2 seconds. When the DLLs are used, the 
results are instantaneous.


As I have already mentioned as a request,  a nice add-on for Revolution 
would be a DLL (and the equivalent for MacOS) for a filter size of 5X5 
or even better 7X7. Photoshop CS (1) allows for the setting-up of 
user-defined filters with a 5X5 matrix. PaintShop Pro offers a 7X7 matrix.


I am not familiar with creating DLLs, but my guess is that it could not 
be too difficult to extend the functionality of Chipp's and Derek Bump's 
3X3-matrix DLL to cover a 7X7 filter matrix.


One thing is missing in the 3X3 Dlls, which include the "division" 
factor - "scale" in Chipp's and Derek's stacks,  namely what is called 
"shift" in Photoshop and "bias" in PaintShop Pro. This is a color value 
to be added to the equation important for instance for creating "relief" 
(and other) effects. I tried to add such a "bias" to Chipp's scripted 
(without DLL) solution, but did not get the same results as with 
PaintShop Pro. Otherwise the PaintShopPro sample filters, so far as they 
fit into a 3X3 matrix, yield the same results in my "ImageFilterDemo" 
that contains a modified version of Chipp's stack.


Especially PaintShop Pro 8 contains about 15 3X3 usable matrix filters, 
versions 7 and 10 only about 5, that could be used in our sample stacks. 
I will add some of these filters to a new release of my ImageFilterDemo.
I might also give it a try - in case I find time - to extend Chipp's 
no-dll version to encompass a 4X4 matrix.

Keep us all posted.  My needs are pretty much always the same -- and  
this would apply to most users needing to get from raw camera to web  
quickly, assuming they don't have time to  tweak levels or fix red-

eye -- or  those who have no clue what that stuff even means.

one  pass: raw Digital camera image.jpg
1) rotate
2) downsize
3) autolevels
4) unsharp mask (I will try sharpening, but for sure it's not as good  
for edges)

5) save jpg "optimize"

Option to turn off 4) 5) above where the image has already been  
through one in interpolation and more  filters will simply degrade.

Re: snapshot and imageData...

[jbv]

yes, there seems to be a speed problem...

in the following example :

on mouseUp
   import snapshot from rect (the screenRect)
   create img
   set rect of img 2 to rect of img 1
   set imageData of img 2 to imageData of img 1
end mouseUp

it looks like lines 2 to 4 are executed before the
completion of the snapshot, hence the "blank" imageData...

I wonder if there's a way to know when the "import snapshot"
is completed to start further processing of the imageData...

Actually, snapshots of large screen is a rather slow process,
and my goal is to loose as little time as possible...

Re: Webcam and Rev?

Roger,

I've had no problem switching between cameras. Try using the Video  
Input stack that comes with Rev, using the Video Source button to  
switch between cameras. You can then save the state of any one camera  
to a custom property or to a separate file so that you can call up  
that camera any time. I am doing this with firewire-based webcams,  
but I do not believe it is any different with a USB webcam.


Let me know if you need more help with this.

you could switch between multiple cameras. Instead, Rev only sees the

Testing here with MC 2.4.3 on OSX seems to work as expected.  The length of

Such a thing would be tough to implement so that it actually looks like
normal scrolling, but I think it could be done.


One of the challenges in using Rev effectively is that it does such a 
good job of hiding the deep nasty work needed to get stuff done from us 
that we often forget how complex these things are under the hood.


What we're talking about here would be a custom list definition in any 
lower-level language.  List defs are complex beasts.


One thing we can learn from list defs (in addition to a healthy 
appreciation for the enormity of the task and how relatively simple Rev 
makes it) is that, generally speaking, they often work much as you describe.


For example, a spreadsheet has only two elements in it:  a custom list 
definition to display the rows and columns, and a single editable text 
field positioned as needed for in-cell editing.


In the Rev world, the ease of working with fields may seduce us to 
forget how complex field objects are, tempting us to use a field for 
every cell.  And for small numbers of cells that works, and well -- but 
with larger numbers it exhibits the performance issues you note.


Extending that idea to use graphics in a list for display, and having a 
single row group for editing makes a lot of sense.  It may take some 
time to set up, but will be more efficient -- it's closer to how one 
would solve the problem in a lower-level language.

I've been using nested groups as custom tables for quite some time, but
curious about the threshold for bad behavior I did some testing:

1. Make a group -- two buttons, two fields, each 23px high, in a row
2. Group it, name the group "record"
3. Make a copy of that group, group both groups, and name the new master
   group "main"
4. Make a button with this script:

on mouseUp
  put 2113 into n
  --
  lock screen
  lock messages
  --
  -- delete old groups:
  repeat with 1 = the number of grps of grp "main" down to 2
delete grp 2 of grp "main"
  end repeat
  --
  set the vscroll of grp "main" to 0
  put 0 into i
  if the optionKey is "down" then exit to top
  repeat n
add 1 to i
clone grp "record" of grp "main"
set the topleft of it to the bottomleft of grp i of grp "Main"
  end repeat
  --
  put the formattedheight of grp "main"
end mouseUp


What I found is that the number shown above assigned to N is the max I
can create here without odd positioning of objects.  If I exceed that I
start getting row groups positioned over other row groups.

The formattedHeight of the "main" group is shown as 32806 --
suspiciously close to 32767 (32k), the old buffer limit for QuickDraw.

So this may suggest that the internal routines for buffering groups is
either using the old QD API, or has internal limits about the same as
QD's.

It's worth noting that 32,806 is almost 38 feet at 72dpi, which is
plenty for most uses so I can't really call this a bug.

But it might make a useful enhancement request to explore extending that
buffer size.

Or would it?  There's already a request for compound-object tables, so
if that gets done will we need position objects for any other purpose
farther than 38 feet in either direction?

Re: number of columns in a table field

many sub groups for the engine to handle quickly.


I've been using nested groups as custom tables for quite some time, but 
curious about the threshold for bad behavior I did some testing:


1. Make a group -- two buttons, two fields, each 23px high, in a row
2. Group it, name the group "record"
3. Make a copy of that group, group both groups, and name the new master
   group "main"
4. Make a button with this script:

on mouseUp
  put 2113 into n
  --
  lock screen
  lock messages
  --
  -- delete old groups:
  repeat with 1 = the number of grps of grp "main" down to 2
delete grp 2 of grp "main"
  end repeat
  --
  set the vscroll of grp "main" to 0
  put 0 into i
  if the optionKey is "down" then exit to top
  repeat n
add 1 to i
clone grp "record" of grp "main"
set the topleft of it to the bottomleft of grp i of grp "Main"
  end repeat
  --
  put the formattedheight of grp "main"
end mouseUp


What I found is that the number shown above assigned to N is the max I 
can create here without odd positioning of objects.  If I exceed that I 
start getting row groups positioned over other row groups.


The formattedHeight of the "main" group is shown as 32806 -- 
suspiciously close to 32767 (32k), the old buffer limit for QuickDraw.


So this may suggest that the internal routines for buffering groups is 
either using the old QD API, or has internal limits about the same as QD's.


It's worth noting that 32,806 is almost 38 feet at 72dpi, which is 
plenty for most uses so I can't really call this a bug.


But it might make a useful enhancement request to explore extending that 
buffer size.


Or would it?  There's already a request for compound-object tables, so 
if that gets done will we need position objects for any other purpose 
farther than 38 feet in either direction?

Re: turning a list into something more complex

[Jonathan Lynch]

I think you could do this by modifying my pseudo-table object:

http://revolution.widged.com/stacks/open/components/spreadsheet_object.rev


Each row already contains a pulldown menu (accessed by right-clicking in the
space to the left of the row). You can just change the options on that
pulldown menu. Each row is a subgroup of the spreadsheet object.

1) delete all rows except row 1
2) Go into the subgroup that contains the items for row 1 and change it to
meet your needs
3) create new rows as needed, using the insert row option in the pulldown
menu for row 1, or by hitting tab when in the very last cell

When it creates a new row, it does so by copying row 1, so whatever changes
you make to row 1 will now be present in every row in the table.


If this will work for you, I can help you with any scripting questions you
might have for using that pseudo-table object.

Take care,

Jonathan

Re: turning a list into something more complex

[Stephen Barncard]

Checkboxes are a pain to implement in a scrolling field. And users 
are presented with a bewildering array of checkboxes.


Why don't you just have the number of checkboxes you need for one 
line off to the side or top of a scrolling field. They could set the 
delimited data line selection to one's or checkmarks (in the line) 
without having to implement check boxes on each line.


In other words, the list, when clicked, would put the data on that 
selection line into one special line of checkboxes and fields for 
data entry and an 'enter' button, which then puts the data back on 
the selection line.


THis is the classic 'list' and 'detail' views of a database.

A popup menu or menus can also be used to alter data in a line.



I asked:
==

I'm writing a program that will eventually create a tabbed line, 
multiple lines

in a field.

Is there any way I can display each line (or a subsection thereof) and place
beside it a series of check boxes or pull down boxes.

peptide 1 1234.5  [chk1]  [..]   [..]  pulldowncolour  pulldownstyle
peptide 2 2334.5  [chk2]  [..]   [..]  pulldowncolour  pulldownstyle

Say I was drawing a graphic controlled by the list, and I wanted to use check
boxes to say "display this" or "Colour this red/green/blue (pulldown)". I have
tried to think this through, but I can't see an easy way at all. The number of
items in the list are such as to require that I can scroll through the items.

Devin, that is neat, and I shall play as soon as I am back at base

create the scrolling list dynamically, or could I make a list of  
say 200 lines, and hide the unneeded ones? If you had an example...:-)


Before I answer, let me just say that Chipp's suggestion (to use  
imbedded graphics in the field in conjunction with the popup command)  
might also be an excellent approach here. It would just depend on the  
types of controls that needed to be anchored to each line of text.


Okay, this is how I'd try appraoching it:

1. The field, and one of each type of control--say one checkbox and  
one option menu--are set up as templates and aligned to the first  
line of the field. Group these, turn on the group's vertical  
scrollbar, and lock the group's location. (set the lockLoc of group  
"mylistgrp" to true)


2. Populate the field with however many lines you need.

3. Use the formattedHeight property to set the physical height of the  
field:
   set the height of fld "mylist" to the formattedHeight of fld  
"myList"


   Keep in mind that the size and loc of the group needs to have  
been locked or the group will try to resize itself to accomodate the  
field's size.


4. Create a copy of the other controls for each line (line 2 to  
number of lines in fld "mylist"). Use the textHeight of the field to  
figure out how much space to leave between each control so that they  
line up with the proper line.


5. Update the hilite of the checkboxes and the contents of the option  
menus to match the contents of the corresponding line, as needed.


This is the basic recipe; the devil is in the details of getting it  
to create and align the needed controls properly. However, once it's  
working I've found it to be fast enough to handle several dozen  
lines--haven't needed to go higher than that so I don't know if there  
is an effective upper limit where it starts to bog down.


I hope this can get you to where you need to be.

Re: Detecting Window's Maximize Window Click

Alex, et al:


 (in Rev, "full screen" is "windowBoundingRect", not "screenRect").



On Tablet PCs, "full screen" is "working screenRect", not 
"windowBoundingRect" or "screenRect".  This is necessary to resize

Re: snapshot and imageData...

[jbv]

Mark,

yes, you're right; but try this :

on mouseUp
import snapshot from rect (the screenRect)
put length(the imagedata of img 1)

create img
set rect of img 2 to rect of img 1
set imageData of img 2 to imageData of img 1
end mouseUp

the 2nd image is just a black rect; although the imagedata
contains more than 5 Mb of binary, it seems that they're
all zeros...

as for Rev doc, just have a look at what it says for imageData
(bottom of the screen)...

Re: number of columns in a table field

my psuedo-table object works pretty well - Marielle made it available on his
site. It addresses many of these concerns.

However, I would not use it for thousands of rows. For a couple hundred
rows, it works ok, but for 2 or 3 thousand rows - well, that is just too
many sub groups for the engine to handle quickly.

Kay,

Sorry, I'm not sure what you're talking about -- of course all those UI
options are great but the way one must use them is not. The standard
method,
I believe, is to use a group the hold all those fields and controls, and
then scroll that group around. But the performance of such a solution is
truly awful when you have to move around hundreds of rows of a couple
dozen
columns. Not to mention that the Geometry Munger likes to resize the group
when it feels like it, and group scroll bars -- horizontal and vertical --
like to resize themselves at will. You end up rolling your own geometry
manager and scrolling manager and resize manager, etc. I do not think it
is
fun to build all these things from scratch, especially when I want to have
some advanced options like splitters and discontinuous selections, proper
cross-platform handling of keyboard controls, response to scroll wheels,
etc., etc. There are various sample stacks out there that try to address
the
shortcomings of the built-in table object, but none of them are perfect...
which just shows you how hard it is to do.

Even rolling my own, I had one standalone where people couldn't scroll to
the very bottom of a group after a certain number of rows were used. And
to
fix it I had to completely delete everything and rebuild from scratch. It
wasn't my code; Rev simply "held on" to something deep in its bowels and
wouldn't let go of it. Groups like to make themselves a couple pixels off
the size of the selected objects so you have a very unprofessional-looking
appearance. More than once I had scrollbar thumbs that refused to move all
the way to the beginning or end of their range. If you're not careful
during
development you can force the group's size to reset and it's difficult to
realign it just right. I don't like having to spend 60% - 70% of my
development time "reinventing the wheel" and working around display
idiosyncrasies just to get a decent grid UI. That is not "software at the
speed of thought" or "rapid application development" by any stretch.

The basic table object can't right-justify or center-justify columns,
easily
lock column and row headings, or even apply its own number formatting
rules
automatically. If a user tries to edit a cell, they get an edit box that
is
much larger than the size of the cell being edited. If you try to edit the
right-most  visible column of a table, Rev forces horizontal scrolling and
the addition of an extra column. Using the built-in, undocumented, set and
get cell commands is slower than molasses; but if you don't use those
methods the contents of the field disappear when you make changes (like
resizing the field) during development. You can't easily select columns of
data, and you can't embed radio buttons, check boxes, or drop-down lists.
This is in sharp contrast to what one can do in FileMaker, Excel, Visual
Basic, and most other development environments I can think of.

I am not making this stuff up, much of it is already documented in
BugZilla.

In short, the Revolution table object is crap and the alternatives are
exercises in frustration. In my opinion ... Attention to *QUALITY* grid
handling is an absolute necessity for the next major update if Rev wants
to
be taken seriously for database work.

My apologies.  I'm still not clear on what Rev is trying to do with the 
maximize box; but I'm going to conclude that my problem boils down to a 
Rev's lack of TCP compliance: Maximizing does _not_ fill the screen 
when the TCP Input Panel is hidden, as it does in MS software.

Well, I tried it on Win XP Pro SP 2 with this code:

if newWidth = oldWidth and newHeight = oldHeight then

it never put "maximized"... it always put the sizes in the message

the numbers I get are something like:

  1280,934,256,256

so it's obvious that there's no match going on...


That code never will (never should) put "Maximized"
What the Maximize icon does, on Win, is flip back and forward between 
"normal" size and "full screen" (in Rev, "full screen" is 
"windowBoundingRect", not "screenRect").


SO one time you should see (something like)
 1280,934,256,256
next time
  256,256,1280,934
next time
 1280,934,256,256
etc.

(When I say "never", I mean "almost never" - you could of course re-size 
the window by dragging until it is exactly the same size as it becomes 
when Maximized - then it should say it matched :-)




Looking more closely at what's going on here it appears you are correct.

What I'm seeing with an empty stack and your script is that clicking 
on the Maximize Box reverses the width & height of the stack on WinXP.


This is _not_ the response I get when clicking the Maximize Box on MS 
applications like WordPad & NotePad: in those cases the Window grows 
to full screen size or shrinks back to "normal" size.


So is there a bug in Rev's Maximize Box logic for Windows?  It 
certainly seems so to moi...especially since the behavior on MacOS is 
different.


It works for me on 2.6.1., WinXP and Mac.  - flips between (in my case) 
927 x 674 and 400 x 400.


(Sorry - I haven't been following this thread closely, so if it's 2.7 
specific, then there may be a problem I haven't seen yet).

By the way, if all you want is to obtain a clean output of man, you may
also use ManOpen:

Ok, sure that's impressive... but now can you write a routine that shows a 
print head moving back and forth and emulates the "clackety clack" noise of 
a teletype machine?

Just kidding! :D

Re: snapshot and imageData...

[Mark Schonewille]

The following scripts work fine in Rev 2.7.1.

on mouseUp
  import snapshot from rect (the screenRect)
end mouseUp

on mouseUp
  export snapshot from rect "100,100,200,200" to myVar as PNG
  set the rect of img 1 to "110,110,210,210"
  put myVar into img 1
end mouseUp

Best,

Mark

Hi list,

when using

I tried with Rev 2,5 and MC 2.4.1

Am I missing something, or is there a way to create the actual

You do it based on the backspaces (numtochar(8))s.

Depends how nicely you need it.

Easy: put numtochar(8) into BS

I get an "Operators + : error in left operand"?

My excuse is I tested it on the Mac, and then typed the email on

replace it by empty string
store the result somewhere


Thank you very much!

Works fine now and is nice enough to display in a field :-)

GREP 
(1) 
GREP(1)



NAME
   grep, egrep, fgrep - print lines matching a pattern

SYNOPSIS
   grep [options] PATTERN [FILE...]
   grep [options] [-e PATTERN | -f FILE] [FILE...]

DESCRIPTION
   Grep  searches the named input FILEs (or standard input if no  
files are
   named, or the file name - is given) for lines containing a  
match to the

   given PATTERN.  By default, grep prints the matching lines.

   In addition, two variant programs egrep and fgrep are  
available.  Egrep

   is the same as grep -E.  Fgrep is the same as grep -F

replaces any pair of chars containing a BS with nothing - so "_BS"  
goes away, and "x_x" becomes simply "x"


Harder:
scan through it looking for BSs,
if previous character is an underscore, then the next char  
should become underlined
if prev char and next char are the same, omit one of the  
duplicates, and make the other bold

Bonjour Didier,


"Double letters" is the way the Terminal displays bold characters...


thanks for the explanation.

But what about : "..._P_A_T_T_E_R_N | --ff _F_I_L_E]  
[_F_I_L_E...]"?

Capital letters, but not doubled.

Any hint on how to correct the display in Rev???
