Re: Deriving an angle from three points

[Phil Davis]

I never took trig, but I imagine some of Rev's trig functions might be 
helpful in determining this. If it's any help, here's a button handler 
that draws the angle:


on mouseUp
   put "40,116/98,186/132,118" into tPointsList
   replace "/" with cr in tPointsList
   set the style of the templateGraphic to "polygon"
   set the lineSize of the templateGraphic to 1
   set the showBorder of the templateGraphic to true -- to show the grc 
edge

   create grc "angle"
   set the points of grc "angle" to tPointsList
end mouseUp

When I draw it, I see there is a right angle at the bottomRight of it 
that might serve as a reference point of some sort? Of course a real 
numbers person wouldn't need to draw anything to "see" this. It would be 
,.


I'll be interested to see the solution too.

How would one determine the angle created from three points, such as those

There are three angles. Which one are you interested in?

One way around this is to use token rather than word, look it up in the Rev
Dictionary.

You need to read it a couple of times and unfortunately it's slightly
erroneous in that some characters, like %, is also a token but not listed in
the first group. But if you experiment a bit you'll find that in all the
examples above only: including ending; ending:

ending. (period)
ending?
and the single instance of a double quote (everything after it
disappears)

are the only ones to cause you problems. Also as eluded to in the
Dictionary, anything between a pair of double quotes is a single token, so
"this is the ending, almost" will appear to Rev as a single token.

So certainly not without it's own pitfalls, but with token there are far
less punctuation characters you have to deal with compared to using word.

NOTE the Note in the Rev Dictionary entry for token. If this is for a
commercial app then maybe token isn't something you should be working with
as it's clearly designed by the Rev team purely to work with the Rev
language, and I suppose subject to change. On the other hand, if you're
writing something one off, I'd go for it.

Sorry, that was supposed to be "beat" not "beta".

(Does anyone ever let the possibility of the answer be "no" stop  
them?)

I had assumed when I saw the following code in the guide:

  put field "data" into tData
  put true into pFirstLineContainsHeaders
  set the dgText [ pFirstLineContainsHeaders ] of group "DataGrid 2"  
to tData


I assumed that  the data grid would function in much the same way  
that FileMaker does when importing an Excel file, i.e. it allows one  
to assign the items in the first line of the file to field names and  
the rest of the llines to populate these fields. That would be a  
reasonable behavior of "dgText[pFirstLineContainsHeaders]" il.e.  
when the parameter is true, the column headings are taken from the  
first line of the text field and the rest go into filling the columns.


The first line is only used to tell the data grid which columns to map  
the rest of the data to. If you want to create columns then you will  
need to set the dgProp["columns"] property.


You can't really use multiple parameters when using setProp (which is  
what dgText is). I'm kind of fudging things a bit by treating dgText  
as a custom property set and pFirstLineContainsHeaders as the custom  
property. The truth is we still don't have access to a very expressive  
syntax when creating custom controls (which the Data Grid is one).

Re: HTMLText question

[Kay C Lan]

Craig,

one further observation. If the field already contains formatted text, ie
bold or coloured, doing what you are doing would set everything back to
plain text except for word 2 so in most cases (but I accept not all) you'd
want to do deal with htmlText exclusively:

put the htmlText of fld "myField" into tHtml --not the plain text
replace "" with "" in line 2 of  tHtml
replace "" with "" in line 2 of tHtml
set the htmlText of fld "myField to tHtml

Of course one case where you would one to swap from one to the other is if
you want to strip HTML tags. Set the htmlText of a field to a html file,
then put the field into a Var, most of the html is then nicely stripped for
you :-)

Re: Newbie Data Grid question

[Jim Ault]

One valuable technique for understanding the DataGrid inner workings.

In Rev, choose the pointer tool, click on a data grid, then go the  
inspector, choose 'custom properties' from the drop down,


and now check out the property sets.  You should see dgProps and dgCache
Note all the properties that have been created when the data grid was  
created.
Of course you can edit the values here, but you can also change them  
in script lines.


One bit of confusion for me is that there is no dgText property set  
visible here.  The syntax


set the dgText [ true ] of group "DataGrid"  to tHeaders

would logically mean that there would be a custom property set "dgText"

Interesting if you click on dgProps "row template" you will see:
group id 1011 of card id 1010 of stack "Data Grid Templates  
1260751174078"


...at least in my version of Rev 3.5

Hope this helps in your travels.

In my code I have this sprinkled throughout all the repeat loops.

if the optionkey is down then
   exit repeat
end if

Then if I hold down on the option key, it drops out of that repeat loop. I 
sprinkle these within each repeat loop so that it drops out of whatever long

Re: interrupting a repeat loop

[Alex Tweedly]

Andre Garzia wrote:

Hi Folks,

this been answered in many ways already but I thought I'd chime in and try
to answer it in a different way. The key is to think of reusable code, every
now and them we keep rewritting the same pieces over and over again. How do
we create a generic thing that will:

1) Run some code in a loop
2) Enable us to stop this execution when something happen

If speed is not the main issue here, then we can approach this with a more
flexible way by creating a group of functions that will enable a generic
handler to be executed until something else make it stop. We will use the
new dispatch calls for that.

command iterate pHandlerToLoop, pHandlerThatInterrupts
   dispatch pHandlerThatInterrupts
   if the result is true then
  dispatch pHandlerToLoop
  if the result is true then
 dispatch iterate with pHandlerToLoop, pHandlerThatInterrupts
  end if
   end if
end iterate

This code will first call a command to check if the loop should be executed,
this command should return true or false. If it is true then it will call
the loop command once and if the loop command returned true, it will call
itself again. This code will loop and will exit the loop if any of two
things happen, the command that interrupts return false or the command that
loops return false, for example, let us count to ten using this code:

  

Nice. But as George said, you will hit recursion limits.

And the dispatch to iterate (i.e. to itself) is a simple tail recursion 
- which you can eliminate easily.


AFAICT, this is equivalent and has no recursion issues.

command iterate pHandlerToLoop, pHandlerThatInterrupts
   repeat forever
  dispatch pHandlerThatInterrupts
  if the result is false then exit iterate
  dispatch pHandlerToLoop
  if the result is false then exit iterate
   end repeat
end iterate

Re: regex/HTMLText question

[zryip theSlug]

Hi Chris,

As said by Jim Ault, I think that you have first to decide the list of whole
word forms you accept.
"space&use&space";"use&comma","use&dot"
=> " use ","use,","use.",".use",".use."...
Once your list prepared, substitute your word by a key that you will replace
at the fly by a word to search.
=> "  ",",",".",".",".."...

Then in a loop treats the different cases with the solution of Craig Newman
likes this:

repeat with aWord in wordList
repeat with aRegex in regexList
put replaceText(aRegex,"",aWord) into wholeWordForm -- replace
the "" key in your pattern by the word that you need
get fld "yourField"
replace wholeWordForm with "" & wholeWordForm & "" in it
end repeat
end repeat

set the htmltext of fld "yourField" to it

This is a first approach because it encloses the word with its possible
punctuation.

Kresten, to clarify what you want, are you trying to create 9 separate
scrolling windows on the desktop, or do you want 9 separate scrolling
regions in one window?

VS: How do I construct a scroll bar for stack larger than screen

[Kresten Bjerg]

Thank you for good advices. 

I have tried to follow them, but am approaching the view, that it cannot
be done.

Which is a shame, because the users of the cheap mini-notebooks would be
a most relevant target group

 It is a most unusual context : A stack, where the stacksize is 3072 x
2304  =  9  different 1024x768 windows,  

which ideally should each have a vscrollbar. 

When I select and group all objects in the first window the
resultant group on inspection defines the size of itself as 

...32162 x 32113..(where it should be 1024x768)  and location 16081 x
16037 ( where it should be  0,0,1024,768) !? 

  and in spite of group inspector indicates vertical scroll  visible, no
such scroll appears in the application browser, nor can it be found. 

 In one attempt somehow a "scrollbar1" appeared in the application
browser, but was fixed at the layer I think 782,

 and resisted all attempts at raising it to a higher layer, to ensure
its visibility. 

I guess part of the problem is that the number of layers has reached
1364, and the number of more or less overlapping groups 

(difficult to identify - several  may be unnecessary mistakes )-
allready is  approximately 183.)

Maybe I should add, that the oversize stack is a substack (meaning that
it can be user-modified in standalones.)

 

(I have previously  placed the former  version, -  in rev
user spaces- under my name: Kresten.

If someone could be persuaded to test, whether my endeavour 

(to adapt the application for use on mini-notebooks  with a 1024 x 600
screen)

 is impossible, and better should be  given up, I will of course be
happy to mail or upload the latest version).

Kresten

Re: Shortcut for resizing a selected object ?

Hi all,

In fact I'm in editing mode with the edit tool when I tried to resize a
button with arrow keys. It's an old (may be bad) habit that I have to resize
objects with arrow keys. I find it more convenient.
When I edit objects it seems that the Message Watcher doesn't receive a
arrowkey message but a rawkeydown/up message.

Re: regex/HTMLText question

[Peter Brigham MD]

Ah, you want to exclude parts of words. Try this:

function wordOffsets str,cntr,wholeWords
   if wholeWords = empty then put true into wholeWords
   -- or you could default to false if you want
   put offsets(str, cntr) into charList
   -- assumes you have the offsets() function to draw on
   -- see my previous email
   if charList = "0" then return "0"
   put the number of items of charList into nbr
   put "" into oList
   repeat for each item n in charList
  if wholeWords and word n of cntr <> str then next repeat
  put the number of words of (char 1 to n of ctr) & "," after oList
   end repeat
   if char -1 of oList = "," then delete char -1 of oList
   return oList
end wordOffsets

This will still be extremely fast unless you're processing megabytes  
of text.

Hi again,

In my previous solution I proposed this loop :

*repeat* until charToNum("s") is in the keysDown

However, the use of "is in" to test the presence of a number in a list is
risky. Because for example, "122" may be in "1222,256"

So to prevent bugs prefers this handler to my previous solution :

 *on* mouseUp

   *put* 0 into fld "Msg"

   *repeat* until charToNum("s") is among the items of the keysDown

  *-- the charToNum function is necessary to compare the key with the
content returned by the keysDown function. The keysDown function returns a
list of keys in ascii form separated by commas.*

  *add* 1 to fld "Msg"

  *wait* 30 ticks

   *end* *repeat*

*end* mouseUp

All I can think of is to grab the text block and use a series of 
"replace" commands to replace each punctuation type with a space. That 
should still retain your word boundaries and relative character 
positions. After that, use regex to get the word boundaries. Presumably 
you won't have to box the punctuation.


Ugly, but might work.

Re: regex question in matchChunk function

[Peter Brigham MD]

Here is one way. These are utility functions I use constantly for text  
processing. Offsets(str,cntr) returns a comma-delimited list of all  
the offsets of str in ctnr. Lineoffsets(str,cntr) does the same with  
lineoffsets. Then you can interate over the list of offsets to do  
whatever you want to each instance of str in cntr. I keep them in a  
utility stack that is in the stackinuse, so it is available to all  
stacks. I don't use regex, as I have never gotten the regex syntax to  
stick in my head firmly enough to find it natural, and in any case  
doing it by script turns out to be as fast or faster.

Given a passage of text, I need to find every instance of certain  
words within that text and draw a box around them. The box drawing I  
can handle just fine by including "box" in the textStyle of the  
found chunk. But it's finding the instances that I'm struggling  
with. Here is my code. Big warning! This should not be run as is, if  
anyone wants to attempt it. The second repeat will go forever.


repeat for each line tWord in tDiffWords
   repeat until matchChunk(tStoryText, "(?i)\b(" & tWord & ") 
\b", tStartChar, tEndChar) is false


   put the textStyle of char tStartChar to tEndChar of fld  
"StoryText" into tStyle

   if tStyle is empty or tStyle is "plain" then
   put "box" into tStyle
   else
   put comma & "box" after tStyle
   end if
   set the textStyle of char tStartChar to tEndChar of fld  
"StoryText" to tStyle


   end repeat
   end repeat

What I need is some way to use the matchChunk function and continue  
the search where the last search ended. I read through some regex  
documentation and came across "\G", but this doesn't seem to work in  
Rev. But maybe I'm not putting it in the right place in my search  
string.


Can anyone help? Is there a way to do this? Or can someone recommend  
another method of accomplishing the same thing? Keep in mind that  
this needs to search whole words in a story passage, and we're  
dealing with all kinds of punctuation here, including hyphens, em  
dashes, etc.

Chris

Thanks, Troy. Unfortunately, offset doesn't quite work for me, as it does not 
honor the wholeMatches property. So I might search for "use", and it would find 
both "use" and "used", which is not the desired result. However, with some 
extra code I could probably make it work (manually checking for punctuation,

Re: regex/HTMLText question

Caution: wordoffset, replace, regEx
You need to decide what constitutes a word.
In Rev,
ending ending. ending, ending?  ending!   ending)   ending]
ending"   ending's   ending=  (ending)
are all words, so the last word in a phrase or sentence cannot be  
matched by wordoffset without a bit of rule checking for punctuation.


The same will apply to regEx since white space/punctuation rules can  
vary.

Two problems: only fields have the htmlText property (as Jerry  
mentioned), and you're mixing literals and an expression. Try:


get fld "myField"
put "" & word 2 of it & "" into word 2 of it
set the htmlText of fld "myField" to it

You need a field for setting HTMLtext.

Re: regex question in matchChunk function

[dunbarx]

I am not either. but:

on mouseup
get fld "yourField"
repeat with y = 1 to the number of words in it
   if word y of it = yourtext then set the textstyle of word y of fld   
"yourField" to "box"
end repeat
end mouseup

Now this writes to fld "yourfield" every time it matches. I think if you 
use the "htmltext" you can work in a variable and set the style all at once. 
Faster.

Hi Tim,

Maybe you could use the keysDown function.
This RR function returns the ascii form of the keys pressed while a handler
is being executed.

For example this mouseUp handler add 1 to the fld msg until the key "s" is
pressed :

*on* mouseUp

   *put* 0 into fld "Msg"

   *repeat* until charToNum("s") is in the keysDown

-- the charToNum function is necessary to compare the key with the content
returned by the keysDown function. The keysDown function returns a list of
keys in ascii form separated by commas.

  *add* 1 to fld "Msg"

  *wait* 30 ticks

   *end* *repeat*
*end* mouseUp


Hope this helps.

- Zryip TheSlug - wish you the best 8)

In the MC IDE, choose Control Browser from the Tools menu. You will see

double-click to open the object's property inspector. It's very fast.

I like MC's control browser too. Sometimes I only want to see what's 
immediately available on a card, not the whole hierarchy of objects and 
stacks. And I really like how I can change the layering order of objects 
so easily in MC, from directly within the browser. Sometimes I do want 
to see everything, so then I look at the stack in Rev. Each IDE has 
advantages/disadvantages.


A couple of things that might make your work in Rev easier:

- You can have open only one script editor at the same time in the Rev 
IDE, the Metacard IDE allows any number of open script editors (which 
simplifies the comparison and editing of scripts)


If you right-click on an editor tab, you can open that script in a new 
window. If you always want new windows and you never want tabs, change 
the option in the Script Editor pane Preferences. That way it acts like MC.




- If you edit a script and close the editor with the close icon - 
instead of the compile button - the tools palette (which disappears when 
you open the script editor) will not re-appear. You have to take a 
detour now to bring back the tools palette, for instance using the 
message box.


Change the option in Prefs that specifies whether to hide palettes when 
opening the editor. This is one of the first things I change whenever I 
set up new prefs. I never want palettes or the message box hidden.

However, note that the default recursionlimit is actually 40, not

Re: Rev IDE vs MetaCard IDE

[Wilhelm Sanke]

I do not care too much how the historical icons look, what I care about 
is the functionality of the Metacard IDE. Above all I like the quickly 
accessible "Control Browser", which is my main tool during programming. 
Also: No interference from front- or backscripts in the IDE.


The workflow - for my needs - is fast, and this is not only because I am 
used to the MC IDE.


The Rev IDE has improved considerably and gradually over time. In the 
beginning it was nearly un-usable, especially with stacks that contained 
a larger number of objects, so you had to produce your own tools for 
specific purposes. What I like most of the present Rev IDE is the 
Dictionary.


Still, there are points that could be improved. A few examples.

- Response speed of the Rev IDE is sometimes slow:
   When the menubar comes up (on a 3 GHz Windows computer), first a 
blank rectangle is shown, after which menuitems and icons apppear.

   Opening menus is especially slow with cards that contain many controls.

- You can have open only one script editor at the same time in the Rev 
IDE, the Metacard IDE allows any number of open script editors (which 
simplifies the comparison and editing of scripts)


- If you edit a script and close the editor with the close icon - 
instead of the compile button - the tools palette (which disappears when 
you open the script editor) will not re-appear. You have to take a 
detour now to bring back the tools palette, for instance using the 
message box.


- Using the Property Inspector, which comes up with a noticable delay, 
and accessing the script needs one step more than in the Metacard IDE. 
But of course, using right-click on an object for getting at script and 
properties is the same in both IDEs.


- Using Rev's Standalone Builder with larger stacks was a nightmare 
until recently (including IDE version 3.5). With some stacks the 
Standalone Builder needed 45 minutes and longer to build the standalone 
- as opposed to one second in the Metacard IDE. Happily this has been 
fixed now with version 4.0, and it should be mentioned that this 
improvement was initiated and supported by a discussion between Oliver 
Kenyon and Metacard users.-


The group of Metacard IDE users - all of which are Rev Enterprise 
license holders - are naturally interested in the further improvement 
and development of Revolution (both the engine and the IDE) and some 
group members have made valuable contributions to this development. This 
is not only because the Metacard IDE - in the same way as the Rev IDE - 
needs and uses the Revolution engine (which, by the way, originated from 
the old Metacard engine). New Rev features are usually integrated into 
the Metacard IDE, too. At present there is work in progress to adapt the 
Metacard IDE to the new standalone building process of Rev.-

Re: How to prevent unlocking the screen

[Jacques Hausser]

Andre

Thank you, I solved the problem, and I think it's a generalisable trick if you 
know exactly how to compute the future size of the stack (perhaps a rare 
situation, but it's my case, the stack has only few possible sizes):
1) compute the future size of your stack
2) lock screen
3) compute the future size and position of every objet in the card
4) set their size and position. They will perhaps be outside the present 
window, but it's not a problem since the screen is locked.
5) only after that, set the new stack size.
Works perfectly well (almost) without a flick !

Re: interrupting a repeat loop

[Andre Garzia]

Good question george, it depends on the works of dispatch call. Let me try
something here, ok did try it, tried computing some big sums and factorials,
it can reach recursion limit depending on memory usage but I've reached
overflow before reaching recursion limits.

But checking the recursionlimits on the dictionary, I see we can increase it
by code! :-O So, if you're going to comput something big, then increase
it!!!

Re: interrupting a repeat loop

[George C Brackett]

Dumb question: could your approach result in too deep a recursion while looping 
some quick code?

George

On Dec 15, 2009, at 1:43 PM, Andre Garzia wrote:

Hi Folks,

this been answered in many ways already but I thought I'd chime in and try
to answer it in a different way. The key is to think of reusable code, every
now and them we keep rewritting the same pieces over and over again. How do
we create a generic thing that will:

1) Run some code in a loop
2) Enable us to stop this execution when something happen

If speed is not the main issue here, then we can approach this with a more
flexible way by creating a group of functions that will enable a generic
handler to be executed until something else make it stop. We will use the
new dispatch calls for that.

command iterate pHandlerToLoop, pHandlerThatInterrupts
  dispatch pHandlerThatInterrupts
  if the result is true then
 dispatch pHandlerToLoop
 if the result is true then
dispatch iterate with pHandlerToLoop, pHandlerThatInterrupts
 end if
  end if
end iterate

This code will first call a command to check if the loop should be executed,
this command should return true or false. If it is true then it will call
the loop command once and if the loop command returned true, it will call
itself again. This code will loop and will exit the loop if any of two
things happen, the command that interrupts return false or the command that
loops return false, for example, let us count to ten using this code:

local lCount

on countToTen
  add 1 to lCount
  return true
end countToTen

on isItTenYet
  if lCount is 10 then
 return false
  else
 return true
  end if
end isItTenYet

on mouseUp mouseButtonNumber
  iterate "countToTen", "isItTenYet"
  put lCount
end mouseup

This has the benefit of splitting the code to be looped from the code that
says if it should loop more, this way, one could simply change the
isItTenYet command to something that checks for the key press without
touching the countToTen function. This code will work for any kind of loop
and it is nonblocking. You can reuse this for example to create code that
reads from sockets or anything mathematical that loops until some condition
is matched.

Instead of using a simple repeat loop with exit conditions and the like
mixed with the logic that should be looped, this will create some clear
distinctions which leads to more readable code in my experience. Reusable
code is your friend!

regex question in matchChunk function

[Chris Sheffield]

I am not very familiar with regular expressions, and I'm wondering if someone 
more knowledgeable could give me a hint as to how to accomplish this.

Given a passage of text, I need to find every instance of certain words within 
that text and draw a box around them. The box drawing I can handle just fine by 
including "box" in the textStyle of the found chunk. But it's finding the 
instances that I'm struggling with. Here is my code. Big warning! This should 
not be run as is, if anyone wants to attempt it. The second repeat will go 
forever.

repeat for each line tWord in tDiffWords
repeat until matchChunk(tStoryText, "(?i)\b(" & tWord & ")\b", 
tStartChar, tEndChar) is false
   
put the textStyle of char tStartChar to tEndChar of fld "StoryText" 
into tStyle
if tStyle is empty or tStyle is "plain" then
put "box" into tStyle
else
put comma & "box" after tStyle
end if
set the textStyle of char tStartChar to tEndChar of fld "StoryText" 
to tStyle
   
end repeat
end repeat

What I need is some way to use the matchChunk function and continue the search 
where the last search ended. I read through some regex documentation and came 
across "\G", but this doesn't seem to work in Rev. But maybe I'm not putting it 
in the right place in my search string.

Can anyone help? Is there a way to do this? Or can someone recommend another 
method of accomplishing the same thing? Keep in mind that this needs to search 
whole words in a story passage, and we're dealing with all kinds of punctuation 
here, including hyphens, em dashes, etc.

Thanks,
Chris

Re: interrupting a repeat loop

[Andre Garzia]

Hi Folks,

this been answered in many ways already but I thought I'd chime in and try
to answer it in a different way. The key is to think of reusable code, every
now and them we keep rewritting the same pieces over and over again. How do
we create a generic thing that will:

1) Run some code in a loop
2) Enable us to stop this execution when something happen

If speed is not the main issue here, then we can approach this with a more
flexible way by creating a group of functions that will enable a generic
handler to be executed until something else make it stop. We will use the
new dispatch calls for that.

command iterate pHandlerToLoop, pHandlerThatInterrupts
   dispatch pHandlerThatInterrupts
   if the result is true then
  dispatch pHandlerToLoop
  if the result is true then
 dispatch iterate with pHandlerToLoop, pHandlerThatInterrupts
  end if
   end if
end iterate

This code will first call a command to check if the loop should be executed,
this command should return true or false. If it is true then it will call
the loop command once and if the loop command returned true, it will call
itself again. This code will loop and will exit the loop if any of two
things happen, the command that interrupts return false or the command that
loops return false, for example, let us count to ten using this code:

local lCount

on countToTen
   add 1 to lCount
   return true
end countToTen

on isItTenYet
   if lCount is 10 then
  return false
   else
  return true
   end if
end isItTenYet

on mouseUp mouseButtonNumber
   iterate "countToTen", "isItTenYet"
   put lCount
end mouseup

This has the benefit of splitting the code to be looped from the code that
says if it should loop more, this way, one could simply change the
isItTenYet command to something that checks for the key press without
touching the countToTen function. This code will work for any kind of loop
and it is nonblocking. You can reuse this for example to create code that
reads from sockets or anything mathematical that loops until some condition
is matched.

Instead of using a simple repeat loop with exit conditions and the like
mixed with the logic that should be looped, this will create some clear
distinctions which leads to more readable code in my experience. Reusable
code is your friend!

Cheers
andre

Re: interrupting a repeat loop

Another way to check for any key being down is:

command runTheLoop
   repeat forever
  if the keysDown <> empty then exit repeat
  -- do what you want
   end repeat
end runTheLoop

If it is not relevant which key is being pressed, then a tad simpler

command runTheLoop
   repeat forever
  if the shiftkey is down then exit repeat

It could also be altKey/optionKey or controlKey/commandKey instead of

Hey, this is great. I will donate.

I like the attention to detail. Also the (unprotected) stack itself is a
good example of some rather nice divider bars, geometry,  practical use of
XML, and plugin design.

There is no replacing going on. However, my stack needs the  
documentation one time for an initial setup. It will thus display a  
kind of Setup wizard when you first start it. After this first step,  
my stack is best used as a plugin to start when rev starts. just put

Re: interrupting a repeat loop

[Jacques Hausser]

Tim, I forgot two little things:

local stoploop

command runTheLoop
  put empty into stoploop -- as stoploop is a "permanent" variable, it should 
already contain "S" and the loop will not run
  repeat forever
 if stoploop = "S" then exit repeat
 -- do what you want
 wait 10 milliseconds with messages
  end repeat
end runTheLoop

on keyDown thekey
   put thekey into stoploop
   pass keydown -- depends of what else is in your card script, without this 
line something else could be blocked...
end keydown

Sorry, I was answering too quickly !

Hello Björnke,
Using dual monitors (one set at a very high resolution), I too would prefer to 
have documentation displaying larger fonts, but that leads to another 
question...

Does your document stack replace the original version or can either one be used 
by choice?

Best regards,
David C.

in a card script:

Re: type font size in dictionary

[Björnke von Gierke]

It's a rev stack, and you can set the default font (of the field the  
content is shown in) to a larger size... however most of the text has  
it's own style, and those are set by scripts, so you'd need to go  
trough the scripts and set them yourself. There's a chance that you  
change the wrong thing and the ide becomes unusable (i hope you feel  
warned). And finally, when rev updates the docu stack, your changes  
might be overwritten.


The easier way is, to use my bvg docu stack, where you can set text  
sizes in the settings:

Re: How to prevent unlocking the screen

[Jacques Hausser]

Mark,

Sorry, I was not crystal clear. When I was talking of copying a picture, I was 
actually transferring the imageData (As an alternative, I also tried to use 
"import snapshot", what works fine  and perhaps a bit quicker). You are quite 
right with the screen unlocking between the two handler in my second solution - 
it was my reason to try the first one first ;-)
And you are perfectly right in suspecting the geometry manager: it is certainly 
the culprit: in my first solution it does its work AFTER the handler resizing 
the image is completed. And the size of images was set in reference to a 
"geometrized" rectangle graphic. So of course the image size corresponds to the 
previous size of this graphic...
I foresee a nice moment to write scripts to control the size of a good amount 
of objects.

Still many thanks, and all the best

Jacques

Re: Newbie Data Grid question

[Andre.Bisseret]

Bonjour Jim, Trevor and others on this thread ;-)

Le 14 déc. 09 à 19:11, James Hurley a écrit :
...


Trevor (and Andre.Bisseret),

Thanks you for the very thoughtful reply(s).

It is heartening to see something defended by its parent. My sincere  
apologies for treating your offspring in such a quick and dirty  
fashion :-)
I'm sure I will appreciate the richness  of this new Run Rev object  
in time--see below.


FIrst to satisfy my quick and dirty needs, I find that the following  
works well to get data displayed in a data grid field:


on mouseUp
  put field "data" into tData --Tab delimited text
  --The first line of tData contains the column names
  put line 1 of tData into tHeaders
  replace tab with cr in tHeaders
  set dgProp["Columns"] of group "DataGrid"  to tHeaders --Thanks to  
Andre for this line.

  set the dgText [ true ] of group "DataGrid" to tData
end mouseUp

Your handler above, confirmed by Trevoir, helped me a lot to  
understand the possible uses of pFirstLineContainsHeaders.
In order to learn more about data grid, I tried several variations, I  
put below in case it could interest someone :


 local tData,tHeaders,
-- field "data" = lines of tab delimited text -- a Data Grid  
"DataGrid" with 3 columns

 

-- 1 ) IF THE LINE OF HEADERS IS NOT INCLUDED IN THE DATA (AS I AM  
ACCUSTOMED TO)

-- 1.1) WITHOUT USING pFirstLineContainsHeaders; WORKS:
on mouseUp
   put "header1" & cr & "header2" & cr & "header3" into tHeaders
   set the dgProp["columns"] of grp "DataGrid" to tHeaders
   put fld "data" into tData
   set the dgText of group "DataGrid" to tData
end mouseUp

-- 1.2) USING pFirstLineContainsHeaders: USELESS BUT WORKS :-)))
   on mouseUp
   put "header1" & cr & "header2" & cr & "header3" into tHeaders
   set the dgProp["columns"] of grp "DataGrid" to tHeaders
   put fld "data" into tData
   set the dgText[false] of group "DataGrid" to tData
end mouseUp

-- 2) IF,  FOR SOME REASON, THE LINE OF HEADERS IS INCLUDED IN THE  
DATA (FIRST LINE)

-- 2.1) WITHOUT USING pFirstLineContainsHeaders: WORKS:
on mouseUp
   put field "data" into tData
   put line 1 of tData into tHeaders
   replace tab with cr in tHeaders
   set dgProp["Columns"] of group "DataGrid"  to tHeaders
   delete line 1 of tData
   set the dgText of group "DataGrid" to tData
end mouseUp

 -- 2.2) USING  pFirstLineContainsHeaders: WORKS:
on mouseUp -- the handler from Jim
   put field "data" into tData
   put line 1 of tData into tHeaders
   replace tab with cr in tHeaders
   set dgProp["Columns"] of group "DataGrid"  to tHeaders --Thanks to  
Andre for this line.

   set the dgText [ true ] of group "DataGrid" to tData
end mouseUp
 -
--   indeed, in all these handlers, it's possible to directly set the  
dgText of grp "datagrid" to fld "data" (but less fast, I guess,  
specially if it contains a lot of lines)

--
 AS FOR THE SYNTAX OF pFirstLineContainsHeaders
OK: set the dgText[true]
nevertheless:
put true into pFirstLineContainsHeaders
set the dgText[pFirstLineContainsHeaders] of grp "datagrid" to true
works as well, but useless, OK :-)

set the pFirstLineContainsHeaders of grp "datagrid" to true does not  
work as that is creating a custom prop; OK :-))


I am a bit slow-witted but I am beginning to understand quite what  
this pFirstLineContainsHeaders can do ;-o)


Thanks to both of you,

André

Re: How to prevent unlocking the screen

Hi Jacques,

When you copy a resized picture, Revolution may restore the original  
dimensions. Copy the picture first, then resize the new picture, or  
use the imagedata of the old picture to set the imagedata of the new  
picture. If you do the latter, set the dimensions of the new picture  
to formattedHeight and formattedWidth.


I strongly recommend not to use the geometry manager. Instead, write  
your own scripts in a resizeStack handler. This is more reliable and  
gives you more control in situations like these.


Your incomplete scripts don't give me a good impression of what is  
going on, hence I can't tell you why the screen unlocks prematurely.  
Do you have an answer or ask dialogue somewhere? Are you repeating or  
waiting with messages perhaps?


Note that locking the screen doesn't really lock the entire screen and  
not even the entire Revolution interface. It only locks windows, while  
they are redrawn in memory.


In the case of your particular stack, when the resizeStack handler  
runs, all other handlers have finished already, because I don't see an  
explicit call to the resizeStack handler. If a handler containing the  
lock screen command finishes, the screen unlocks. This means that  
screen will unlock before the resizeStack handler runs.


Just a few thoughts. I hope this helps.

Thanks, Mark. Works for almost everything, except for a copy of a  
picture (I have the original picture hidden and resized in the  
background, and a visible copy of it to work on). I tried two  
solutions


1) resize the original picture and recopy it in my changeStackSize  
command:


command changeStackSize
  lock screen
  -- (computes and sets the new size)
  resetpicture -- (resizes the original picture and recopy it)
end changeStackSize

The picture is not resized... why ?

2) catch the resizeStack message and resize the picture from there

command changeStackSize
  lock screen
  -- (computes and sets the new size)
end changeStackSize

on resizeStack
  lock screen
  revupdateGeometry
  resetpicture - (resizes the original picture and recopy it)
end resizeStack

the picture is resized OK, but you see the two successive steps on  
the screen...

Needless to say that resetpicture is the same in both cases...

Hi Jacques,

Lock screen, change stack size, change content, unlock screen. This  
should give acceptable results. This is a script, which I use in a  
project of mine:


 revChangeWindowSize the width of this stack,the cNewHeight of cd  
"Destination Card","Slide",,100

 lock screen
 go cd "A different card"
 resizeStack // update contents here
 unlock screen with visual effect dissolve very fast

(mind line wraps, if any)

Hello everybody,

I want to change the size of a stack:

command changeStackSize
 lock screen
 -- (computes and set the new size)
end changeStackSize

The problem is that notwithstanding the "lock screen" the change is  
visible in two steps: first the window size, and then the content. I  
would like to hide the change till completed. How to do ?

Thanks in advance

Jacques
