Screen refresh problems in OS X
Unfortunately the planned fix for the refresh problem in OS X will have to await a later update. The fix had repercussion elsewhere in 2.7.1 (fields particularly) and so we will have to await 2.7.2.

To: use-revolution@lists.runrev.com Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1 I¼ve just started playing with Revolution having been a passionate enthusiast for Hypercard in a previous life. One thing I¼ve hit upon early on that annoys me a little. Though Revolution is far newer, and loads into memory rather than writing to disk, it is still way slower at certain things such as refreshing text fields than Hypercard ever was. I wrote the following counting routine (as a speed test to measure the difference between writing to a variable and writing to a field). However, what I learned was that on my computer, at any rate Revolution only refreshes its text fields slightly more than once a second. When I run the same script on Hypercard, the counting field whirs through changes faster than a gas pump - with every new number registered on screen. Revolution only shows me about one figure in every twenty five or so despite the fact that the routine tells the field to display every consecutive number from 1 to 300. Just add this script to a locked text field, and click on it, to see what I¼m talking about: on mouseup -- COUNT TO 300 put the ticks into startTime repeat with i = 1 to 300 put 1 + line 1 of me into line 1 of me end repeat put the ticks - starttime into stopTime1 put stopTime1 into word 1 of line 3 of me put the ticks into startTime put me into testVar -- NOW JUST SHOW MULTIPLES OF TEN repeat with i = 1 to 300 put 1 + line 2 of testVar into line 2 of testVar if i mod 10 = 0 then put line 2 of testVar into line 2 of me end repeat put line 2 of testVar into line 2 of me put the ticks - startTime into stopTime2 put stopTime1 : stopTime2 into line 3 of me end mouseup Eric, You didn't mention what operating system you are using.

But Jacque, I know you can do fractals with your math tied behind your back. The beauty of Turtle Graphics is that all the analytical stuff is done for you. The rest is a little geometry using such commands as: Forward, Back, Right, Left, to handle the local geometry, and setXY, incXY to deal with the coordinate stuff. It is amazing what you can do with this tool. There are books, written by MIT math professors, using TG to do special relativity. To do the snowflake all the geometry you need is to recognize that: on drawSide L forward L left 60 forward L right 120 forward L left 60 forward L end drawSide will draw a four segment line with a angular (60 degree) bump in the middle. The hard part, at least it's hard for me, is to recognize that the recursive version of this is: on drawSide L if L 3 then --Three is a measure of the smallest fractal segment to be considered. divide L by 3 -- Or whatever drawSide L left 60 drawSide L right 120 drawSide L left 60 drawSide L else forward L end if end drawSide And that takes a while to see.

ANN: Displacement Scaling of graphic objects
Scaling is a very common feature of all graphics applications, e.g. Illustrator and Freehand. But there is another type of scaling that is sometimes useful; for lack of a better expression I'll call it displacement scaling. (Thanks to a suggestion from Scott Rossi for bringing this up.) As a simple example, consider a rectangle of width w and height h. If you magnify this in Illustrator or Freehand by an amount m, you get a rectangle with sides m*w and m*h. This preserves the geometrical features of the rectangle. For example the tangent of the angle between the diagonal and the base is h/w in both rectangles. But suppose you wanted to make a frame by putting two rectangles together, one inside the other. You would want all the sides of the expanded rectangle to be at a uniform distance, say d, from the original--as in a frame. This expanded rectangle does not preserve the geometry. The tangent of the diagonal angle becomes: (h+2d)/(w+2d), which is not the same as h/w. In fact, for large displacements, the rectangle becomes a square--the tangent approaches one. (Similarly, an expanded ellipse approaches a circle.) The stack ScaleMe performs this displacement scaling on all polygons. (It also applies to any polygon with sufficient points that it approximates a curved figure, for example an ellipse.) It presents some interesting problems, particularly when the graphic points are numerous and close together--as in an ellipse. In this case it is necessary to define the points of the graphic, not by Run Rev's graphic points (with just 3 significant figures) but with the full precision of Run Rev's decimal calculations. The calculated graphic points are stored in a custom property of the graphic. The points then are stored both as the customary 3 digit graphic points for purposes of display and as a decimal (8 displayed , 15 total?) digits for purposes of calculation. (Scott: This eliminates all the problems we had with such figures.) The stack shows how to create some dazzling graphic figures by repeatedly scaling a simple form and setting each displaced figure to a different color. It also touches on fractal graphics.

I am making a stack to teach students math -- linear equations, to be more precise. When I display the y = mx + b form, the best I can do to show a fraction in the m position is something like y = 4/5x + 2. This is ambiguous because it isn't clear what should be taken as the divisor, 5 or 5x or 5x + 2. The math teacher for whom I am making the game would prefer a horizontal division line instead of a slash. So far this is what I've thought of and rejected: Use fonts that have fractions built in as one character. No, because they have too few for the range of possible slopes I want to generate. Force the numerals around as subscripts and superscripts until it is clear what the fraction is. Messy and probably won't lead to success. Use inline images. Need too many images to cover possible slopes. Write it y = (4/5)x + 2. This is mathematically acceptable, but not the way the students will see it elsewhere. Use a different 2-line field that moves according to the location of the fraction. Hmm.. maybe. I could use some help on this one.

Re: Don't understand the meaning of local
Type: text/plain; charset=ISO-8859-1; format=flowed Jim, If you declare your local outside the object handlers, then it stays persistent to that object *until* you edit the script. Editing scripts resets all it's locals. best, Chipp Chipp, Thanks. That is what I was missing. I was also finding that when I returned to the script the old local variable retained its value from the previous run--until, as you say, the script is recompiled. Local is a deceptive descriptor. It is used (as a script local) to control not only locality, but also persistence--it has both spacial and temporal implications. I'm not faulting the docs. It's all there.

Re: Don't understand the meaning of local
Message: 7 Date: Fri, 23 Dec 2005 09:24:41 -0800 From: Jim Ault [EMAIL PROTECTED] Subject: Re: Don't understand the meaning of local To: How to use Revolution use-revolution@lists.runrev.com Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=US-ASCII Local is a deceptive descriptor. It is used (as a script local) to control not only locality, but also persistence--it has both spacial and temporal implications. Perhaps it is the terminology used in the docs. More precisely, I think of it as *handler local, *script local, and *global to Rev variables. The handler local is the one that dies when exiting that handler. This allows the same variable name (eg. tempVar) to be used without carry-over. Also, 'set the itemDel to space' only applies to that running handler. Entering another starts with the default itemDel, so this is a 'handler local' setting. Important concept for front/back scripts and stacks in use Globals are held by Rev and only die when either delete variable gGlobalVar --is done the user quits Revolution app. This means that you could build a stack that is opened, sets some globals, close with the 'destroyStack' as true, leaving the globals in RAM and available to all stacks and sub stacks. Obviously, the kinder, gentler stack design is to delete these variables on closeStack. Good questions. Jim Ault Las Vegas Jim, Good points. The persistence of local SCRIPT variables that Chipp's earlier reply clears up for me is handlers calling themselves (in x millisec or whatever) in order to achieve asynchronous behavior ( i.e. not monopolizing CPU time and allowing other uses of the CPU to seek in.) Unless the script remembers the local script variables (until the next compiling of the code) then on the next call the handler will not know what values to assign. On way around this would be to include the value of the variable in the call. For example in the following script the send message tells the handler what the value of the variable should be after 20 millisec is up. on mouseUp put into field 1 checkPersistence 1 end mouseUp on checkPersistence tNum if tNum 10 then exit checkpersistence put tNum into field 1 send checkPersistence tNum + 1 to me in 20 millisec end checkPersistence And there would be no need to include a script local variable. But if checkPersistence look like this: on checkPersistence if tNum 10 then exit checkpersistence put tNum into field 1 add 1 to tNum send checkPersistence to me in 20 millisec end checkPersistence It would not work unless tNum was declared earlier as a script local. It's about time I'm getting these fundamental points straight. There is a danger in learning RR on an as-needed basis.

Don't understand the meaning of local
I suspect that this issue has been dealt with before, but I don't get it. I thought I understood what a local variable was. Create a field. Put a bunch of returns into it--or several lines of text. Lock the field and put the following script into it. Hold the mouse down and move it through the field. I would have expected a list of the lines that have been moved over to appear in the msg box. Instead only the current line is shown. But I so get the entire list if I include tLines as a local script variable. Apparently tLines is set to empty after every execution of mouseMove, unless tLines is included as a local script variable. I get the feeling that mouseMove stops and restarts with every cycle and therefore forgets the value of tLines. However if tLines is set as a local script varable then the script continues to run and therefore remembers tLines. I had thought that the function of the local script declaration was to allow the variable to be used throughout the handlers of the script. However, in this example tLines is used only in mouseMove. I think I ran into this behavior earlier when adding a rolling snowball asynchronously to Scott's snow storm. I wondered why local variables were kept in memory each time a handler called itself after a few milliseconds. Once again it appears that setting a local script variable retains the variables in memory--even when the script stops (?) until called again. Anyone understand the different behavior of this script depending on whether tLines is declared as a local script variable? Or, more challenging, can anyone explain it to me? local myName, --tLines on mouseDown put the name of me into myName end mouseDown on mouseUP put into myName end mouseUP on mouseMove if myName is then exit mouseMove put word 2 of the MouseLine into tLine if tLine is not in tLines then put tLine comma after tLines put tLines into msg box end mouseMove ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

I would definitely say revCrumplePoly is a better name for the revRotatePoly command. Is there any situation where revRotatePoly could be useful? Not if it does this. Totally bugged.

If this is the case, then Rev should store fractionals, but render to integers.) Here, here. I have been promoting fractional coordinates for graphic points for some time. Try the following handler: on mouseUp set the loc of me to 200.6,200.4 put the loc of me into msg box--reveals 200,200 set the points of grc 1 to 100,100 cr 200.4,200.6 --There is no evidence of the line graphic -- The fractional point is not truncated but interpreted as a blank line. end mouseUp RR will accept fractional coordinates for controls (it truncates the coordinates) but it will not accept fractional graphic points. You don't get an error message and no feedback that the problem lines in the fractional coordinates. Problems arises when the graphic points are computed; the programmer may not realize that the points are fractional or that RR will not accept fractional points. Any point with a fractional coordinate is interpreted as an empty point and therefore a discontinuity. It has been a while and I forget the details, but I think there was support for this change in RR; so far no implementation.

Re: OT Last week's CarTalk puzzler
I guess I can assume you have all had time to work on this beautiful problem. But if not, read no further. I really like the solution that Charles Hartman provided. Simple and precise. It wasn't the solution I had in mind at all. There is another approach, not as quick as Charles', but it not only demonstrates when the number of factors is odd or even, but it also provides a method of obtaining how many odd or how many even factors there are, and, as a bonus, as a process for finding those factors. From the fundamental theorem of arithmetic any number N can be represented as a unique product of primes N = p1^n1 * p2^n2 * etc. where p1, p2, etc are prime numbers, and n1, n2, etc. are integers The factors of N are then p1^m1 * p2^m2 * . etc. where m1 takes on values from 0 to n1, m2 takes on values from 0 to n2, etc. The number of factors is therefore: (n1 + 1) * (n2 + 1) etc. This product will be odd if and only if EACH of the brackets is odd; But (n + 1) is odd if and only if n is even. If all the n's are even, it follow that N is as perfect square. Similarly for the odd number of factors. For example, if N = 24 then its prime factor representation is 24 = 2^3 * 3^1 And the number of factors is the exponent 3 plus 1, times the exponent 1 plus 1, or 4 * 2 = 8 Explicitly the 8 factors are: 1,2,3,4,6,8,12,24 Each factor is 2 to some power less than or equal to 3, multiplied by 3 to some power less than or equal to 1.

Re: OT Last week's CarTalk puzzler
Charles Hartman wrote: Interesting. At first it looks straightforward: 1. If a factor is by definition an integer that when multipilied by another integer yields the number we're interested in as a product, then factors have to come in pairs. (It takes two to multiply.) 2. Odd number of factors is therefore a contradiction in terms, unless factor is shifted to mean unique factor. 3. If a number has a pair of factors that are identical (so not unique, so they only count once), then it's the product of that factor (which provably can't be either 1 or the number itself), times that factor, which is the definition of a square. So having an odd number of factors is a sufficient condition for being a square. But it doesn't seem to be a necessary condition. The factors of 36 -- by the double definition you have to use in order to make sense of the statement of the problem -- are either 1 36 2 2 3 3 or 1 36 2 3 Charles, The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36; an odd number of factors as the theorem predicts. The factors of 32 are 1, 2, 4, 8, 16, and 32; an even number of factors, again consistent with the theorem. The only way I know to solve this problem, i.e. show that the number of factors of a given number is odd, if and only if the number is a perfect square, is to express the number as a product of primes. For example 36 = 2^2 * 3^2 And 32 = 2^5 In case anyone wants to pursue this further, I will quit here. Beauty is best enjoyed if you discover it for yourself.

OT Last week's CarTalk puzzler
For those of you who find beauty in mathematics. Below is this week's CarTalk puzzle. (A National Public Radio program on cars and car repair, hence this beautiful puzzle in number theory--don't ask.) At first I didn't believe Ray theorem (below), so I used Run Rev to at least confirm his hypothesis: All numbers with an odd number of factors is a perfect square, i.e. the square of an integer, 1, 4, 9 16, etc. As an example: 16 has as factors, 1, 2, 4, 8 and 16. There are 5 factors, an odd number. This implies that the 16'th bulb will be switch an odd number of times and therefore will be off if initially on, and on if initially off. Sure enough a little repeat loop shows that the theorem is true. To prove it you may find the fundamental theorem of arithmetic helpful, i.e. Every integer may be uniquely represented as a product of prime numbers. (20,000 is just an arbitrarily large number.) Jim PUZZLER: The Hall of 20,000 Ceiling Lights There are 20,000 lights on. A person comes through and pulls the cord on every second light. A third person comes along and pulls the cord on every third light, etc. When someone comes who pulls every 20,000th chain, which lights are on? Their solution(?): The Hall of 20,000 Ceiling Lights RAY: Let's number all the lights and pick one at random. TOM: How about 26? RAY: OK, let's look at light number 26 and figure out if it's going to be on or off. All we need to know are the factors of the number 26. Well what's a factor? A factor is a whole number that will divide evenly into another number, with nothing leftover. So, the factors of 26 are 1, 26, 13 and 2. Here's why that's important. It tells us that light number 26 is going to get its chain pulled four times. TOM: How did you figure that out? RAY: Well, when every cord gets pulled it gets turned on, right? Light number 26 gets its cord pulled again at 2, which is a factor of 26. When every 13th chain gets pulled, light number 26 gets turned on again. And it doesn't get touched again until 26, when it gets turned off forever. Now it's pretty obvious then that every bulb that has an even number of factors will eventually get turned off for good. So, which lamps remain on? All those represented by a number with an odd number of factors. And those are, are you ready for this? Light bulbs 1, 4, 9, 16, 25, 36, etc. All those numbers are called perfect squares. And only they have an odd number of factors, because one of the factors is the square root of the number in question. For example, nine has three factors, 1 and 9 and 3. [I confess, I can't see how this follows. Jim] Do we have a winner? TOM: We do have a winner and the winner this week is Laurie Warner from Greer, South Carolina. And for having her answer selected at random from among all the correct answers that we got Laurie gets a 26 dollar gift certificate to the Shameless Commerce Division at Car Talk.com, with which she can pick up our new best and second best of Car Talk CD pack. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: Difference between Step over and Run
Jim Hurley wrote: I have noticed in the debugger that there is quite a difference in time of execution between Step over and Run I think this is because of the traceDelay. When you are debugging, every step includes a pause equivalent to the traceDelay setting. When you run, the engine goes back to full speed. snip stuff Moral: Even though the screen is locked by script, it is not locked when running the debugger, UNLESS you Run to the next line. And it will run though the window work much faster if you unlock the window. Unless someone recognizes this as a known bug in the debugger, I will submit it. I believe this behavior is intentional. The assumption is that during debugging you always want to see what is happening. There have been innumerable instances where I was happy it worked that way, because I could see the screen change during debugging without altering my code temporarily. Jacque, Yes, I understand and appreciate this facility. To understand my point you need to run the following script: on mouseUp put into field 1 lock screen --Try with and without this line. doWindowWork --With a break point maker here beep end mouseUp on doWindowWork put the ticks into tStartTime put 1 into field 1 repeat 100 add 1 to field 1 end repeat put cr the Ticks - tStartTime after msg box end doWindowWork First, step over doWindowWork with the screen unlocked. You see the values in field 1 change (rapidly) from 1 to 100. It take about 30 ticks. This is the way I would hope the debugger would work in this case. Next, step over doWindowWork with the screen locked. You again see the values in field 1 change from 1 to 100, but this time very slowly--it takes about 1000 ticks. In both cases you see what is happening but at a very different pace. Many times in the stack I was working on, there was so much field work being done that Step over is not feasible with the screen locked--taking several minutes to execute. (The screen was locked precisely because of this field activity.) The work around is to strike out the screen lock line in the script. A bit of a nuisance, requiring one script without the debugger and another with the debugger. Or better, if viewing the field changes is not important, then running to the next line of code. My suggestion would be that the debugger would reveal the field changes at the same pace with and without the screen lock when stepping over the line which effects the field changes. Sorry; long winded and perhaps a point too fine. And I'm afraid I confused the issue with the subject line of this post.

Difference between Step over and Run
I have noticed in the debugger that there is quite a difference in time of execution between Step over and Run even when Run takes me to the very next line of code--a line which is also a break point. When the handler to be Stepped over is complex, the time to execute Step over can be prohibitive. In such cases I set a break point at the next line and Run to the next line. This is VERY much faster. Is this a bug? Wouldn't it be better if RR executed Step over as if it were a Run to the next line of code? Does the Step over do something other than Run to the next line when that next line is a breakpoint?

(I don't own a cell phone, but I appreciate them nevertheless. I can hold my hand to my ear and talk to my imaginary friends without attracting undue attention.) Here is an example of the problem I have with the debugger. The following handlers are in a button script: on mouseUp lock screen doWindowWork--There is a break point marker at this line. beep--There is also a break point marker at this line. end mouseUp on doWindowWork put the ticks into tStartTime put 1 into field 1 repeat 100 add 1 to field 1 end repeat put cr the Ticks - tStartTime after msg box end doWindowWork When I run MouseUp and Step over the line doWindowWord in the debugger, it take 1100 ticks to get to the next line, beep When I hit Run at dowindowWork it takes 10 ticks to run to the next line, beep Now it gets really weird. If you comment out the lock screen line it takes only 30 ticks to step over the doWindowWork line. The doWindowWork is 30 fold faster if the screen is not locked. (This applies only to scripts run in the degugger.) Moral: Even though the screen is locked by script, it is not locked when running the debugger, UNLESS you Run to the next line. And it will run though the window work much faster if you unlock the window. Unless someone recognizes this as a known bug in the debugger, I will submit it.

Re: Constrain Within Circle?
From: Roger Guay [EMAIL PROTECTED] Cool, Jim. And, if you change just one line of your code in the mouseMove handler to if rr is not r then you get an object that is constrained to move on the circle of radius rr. This is useful if you want to build a rotary knob for example. Roger, Scott and I were working on a problem like the one you describe some time ago. But the question was: Could the rotary knob be used to *accumulate* multiple turns by following the the polar angle. The difficulty here was that the angle as reported by RR using the atan2 function is single valued, that is it returns to the same value after one complete revolution. How then do you record the angle *plus* the number of revolutions? But as the knob crosses the branch cut where the angle changes from 360 back to 0, one can detect this large discontinuity using something like: if abs(da) some small number then add 1 to the counter and multiply this counter by 360, where da is the continuously measure difference in polar angle in the mouseMove function. This is hard to explain.

ANN Sukodu puzzles--again
Our local paper has begun to carry a daily Sukodu puzzle. A friend challenged me to solve one that he had trouble with. I couldn't find a solution; I kept running into situations where I could find no possible entry without guessing. To work on it I loaded up Alex Tweedly wonderful Sukodu Assistant. But I needed something that would determine in there was a unique one-stage solution, i.e. a solution in which there was always at least one cell with a determined digit, given the present configuration. Well, one thing lead to another and Sukodu--see below--resulted. It uses Alex's very nice interface. The drop down menu is an excellent way to enter this limited assortment of discrete data into a field. The stack also does an analysis of the puzzle after each step and will display in each cell the possible entries. It also looks at the constraints on rows, columns, and blocks, to determine what's possible in these components--applying the restriction that each row, column and block are to contain all nine digits. This analysis is displayed in separate fields. If you choose the mode in which this info is displayed, the solution to any puzzle will be trivial. But I found it a very useful tutorial to run through a few of the harder puzzles this way. There were strategies available which I had never guessed at. (You can toggle the display of this analysis on and off with a right-click or control-click. You can turn any entry green with a shift-click. This is useful if you have to make a guess. Then, if you run into a contradiction at some point down the road, you can undo back to the green entry.) When the puzzle is first loaded, the stack uses this analysis of rows, columns and blocks to run through the puzzle (with the screen locked) step by step to obtain a solution--if there is a one-stage solution. With this solution available, it is then possible to choose a mode of play which will not allow an incorrect entry into a cell--comforting. I have tested this in Mac OS X, but not thoroughly in Windows. I had one stinker of a problem with the Window version. It read a menuPick handler in a button which I had commented out, and did not pass the menuPick message to the card. Took a while to find this bug. Turned out that the puzzle my friend had given me was missing a number. With friends like this The stack (and file folder) are at: http://home.infostations.net/jhurley/SudokuFolder.zip Keep the file folder with the stack. The folder contains a few additional puzzles and a place to save your own. I may never do one of these Sudoku puzzles again.

Re: ANN: Simple Pendulum Simulation
Thanks, Jim. I do indeed have this inclination. In fact my original intent was to use the simple pendulum to learn and apply the Runge- Kutta Method. I just haven't gotten around to it yet. Might your suggestion be a variation of this? Cheers, Roger Roger, Actually I was thinking of something even simpler than the Runge-Kutta approximation. Using the Euler approximation, the repeat loop to generate the pendulum motion is really simple and looks like this: repeat until the mouseClick setRA r,270+psi -- Polar coordinates; 270 so that the pendulum hands DOWN add -c*psi to angVel --Add angular acceleration to the angular velocity add angVel to psi --Add angular velocity to the angle end repeat where psi is the angular displacement of the pendulum. I am using Turtle Graphics, but I think you get the idea. To see this in action, put this in the message box: go stack url http://home.infostations.net/jhurley/ControlGraphics.rev; and go to the last card. Control graphics is a variation on TG. It allows you to identify any control as a Turtle which not only responds to Transcript, but also to TG. So you can create a circle graphic and call it pendulum and then talk to the circle like it was a turtle, i.e. forward 10, right 90, setXY 20,30, setRA 200,35 etc. Polar coordinates are particularly useful in the pendulum problem I tried to show the dependence of the period on the amplitude but no luck so far. Maybe Runga-Kutta is required. The period depends on the amplitude (to second order in the amplitude) in this way: T = T(0) (1 + A^2/16) where A is the angular amplitude in radians.

Re: ANN: Simple Pendulum Simulation
A simple simulation of a simple pendulum . . . revOnlin - User Spaces - RogerG or Education. Cheers, Roger Roger, Nice job! Good interface. If you have the inclination, you might want to tackle the large amplitude pendulum. There is no nice analytic solution but you could numerically integrate the equation of motion. Something like this: Let A represent the angle. Then you would do a numerical integration with repeat loop set the location of the pendulum to R,A --using radial coordinates add c * sine(A) to the angular velocity -- where c depends on the mass, L and g --The angular acceleration is proportional to the torque which is proportional to sine(A) --For small amplitudes sine(A) = A, in radial coordinates add the angular velocity to A end repeat loop Where I have assumed the time interval between loops is one second, so that dt =1 It would be interesting to show how the period (determined by the number of loops between changes in sign of the angular velocity) depends on the amplitude. Show that the clock slows down as it runs down, i.e. the period decreases with decreasing amplitude--albeit slowly; it is a second order effect in the amplitude. That's why pendulum clocks work so well.

Re: Creating sub-menus a la the inspector?
Hi Jim, If I understand correctly your question, you want to build a menu with sub-menus (a hierarchical menu). That's easy using tabs you place in front of menu items to specify they are sub-menu items. With this method, you can build hierarchical menus including as many rows as you need. You will build your menu on-the-fly at mouseDown in the way you want according to the number of items you have to display :-) Have a look at my How to Build and Manage Dynamic Menus available from Tutorials Picker to get started: . How to build on-the-fly a menu with sub-menus from an outline stored into a custom property. . How to add contextual items, checkmark, activate or disable menu items, etc. . How to respond to the user's actions: choosing a menu item, using a keyboard shortcut, etc. Hi Eric, Thanks a lot. I tried using the tab before, but all I got was something like: Choice 1 Sub a Sub b Choice 2 Sub c Etc. That is the literal result of what I put in the button text. On exploring further, I see the tab creates a submenu only in Pull Down and Pop Up styles. I think that was where I went wrong earlier. Small bug: If you create a PullDown button, change it to a Combo Box, and then back to a PullDown, the button name disappears. Only by putting the cursor into the Labels field and hitting return, will the button name (not the label name) reappear. This applies to 2.6 and 2.6.1 alike.

If this is the first time you've heard of StackRunner, StackRunner is a simple player application that is similar to the DreamCard Player in that it will play your MetaCard or Revolution stacks, but it is much simpler and doesn't present any user-interface elements so it runs cleaner. It's free, so you can distribute it with any kind of stack. You can get more information and download it here: http://www.sonsothunder.com/devres/revolution/downloads/StackRunner.htm Enjoy! Ken Ray Sons of Thunder Software Web site: http://www.sonsothunder.com/ Email: [EMAIL PROTECTED] Ken, Just a note to say how useful I found StackRunner recently. I was working on an application for a friend of mine. There was a lot of back and forth. But I only needed to update the file; no need to send a giant standalone. Thank you so much for this.

I am working on a transcription stack, i.e. a stack which will speak an audio file while the user types what he or she hears into a field. There is no field script. The card script is: on keyDown theKey switch theKey case / send mouseUP to button pause break case \ send mouseUP to button resume break default pass keyDown end switch end keyDown When the user types a / the speech pauses. When the user types \ the speech resumes--actually it backs up a little bit and then resumes. The keyboard replaces the usual foot pedal in transcription hardware. What I found surprising (and welcome) is that the back and forward slashes never appear in the field. The key stroke is never passed back to the field for display after it is caught by the card script. (It would be if there were a pass keyDown in the first two case statements.) So apparently the field gets the message first, then then card (as you both say) and then, if the key stroke is passed by the card script, it is passed back to the field display for viewing. I was wrong to speak of this last message as part of the conventional message passing path. Maybe display message? The keyDown message is never *displayed* unless it is passed through all of RR message handlers--display is the last in line. And as Martha Stewart would say: It is a good thing.

I was puzzled that you weren't getting the static that I get when the thumbposition of the scrollbar is set with the update. Turns out that my scrollbar has a scrollbarDrag handler which sets the currentTime of the player. (I want to be able to drag the thumb to any point along the bar. This allows me to choose the starting point with the slider.) What I needed was a way to avoid the execution of the scrollbar handler when the thumbposition was moved by an external handler, but to allow the script when the thumb was dragged. That can be done with the same device one uses in a mouseMove handler. I added a mouseDown handler in the scrollbar which puts a value into the variable myName and then exiting the scrollBarDrag handler if myName is empty.

Re: Can one pause revSpeak?
As an alternative I have put this handler into the field: on mouseUp put the clickchunk into tChunk set the tClickChunkStart of field 1 to word 2 of tChunk revstopSpeech end mouseUp And stop speech by ckicking on the point where I wish the next speech to begin on resuming. And then resume speech from char tClickChunkStart to char -1 of field 1. How about setting up a loop that reads a sentence then waits until revIsSpeaking goes to false. After that, check for a key or mouseDown or checkbox set and either go on to the next sentence or stop, while remembering which sentence was next. Then a Resume button or keystroke could start the loop again. Cheers, Sarah Sarah, That works. It has the advantage that the locktext of the field can be set to false, leaving the field open to editing. The advantage of using the clickChunk is that I have more freedom on where to resume speaking. No need to begin at the next sentence. I will try both for a while to see which works best.

Can one pause revSpeak?
I use Run Rev to read articles back to me. I find that it is a useful writing tool, both for purposes of style and finding typos. There is a big difference between the written and spoken word and it is helpful to have both at one's disposal. I have a little stack for this purpose. Very simple. Two buttons and a text field. The script for the start button is: on mouseUp get the selectedText if it is then get field 1 revspeak it end mouseUp And the stop button is just revStopSpeech. But as I listen, I find things I want to change. This means stopping speech, making the change (in Word, not in the RR field) and then selecting the text from the stop point. It would be nice if I had Pause and Resume buttons which would allow me to pick up where I left off without having to find the stop point and re-select the text.

It is fairly quick, about 8 or 9 millisec. But, as I said, there would be a fair bit of calculation required to GET the proper loc, dimensions, and angle.

It would be difficult even to make it a well-defined problem, i.e. a problem with a unique solution. Given an ellipse which fits inside a given quadrilateral, one would always rotate the ellipse a bit and fiddle with it a bit to find another. And only in a special case would the ellipse be tangent to the quadrilateral at the midpoints of the four sides. Do you want to do this dynamically in your stack or just illustrate some examples? Would it help to fit bezier curves inside the quadrilaterals?

This can be part of the config.srn file, or you you let it take its default behavior. For more info, please see: http://www.sonsothunder.com/devres/revolution/downloads/StackRunner.htm Have fun! Ken Ray Sons of Thunder Software Web site: http://www.sonsothunder.com/ Email: [EMAIL PROTECTED] Ken, Thanks for the Runner. I love the simplicity. I have had no occasion to use DreamCard so I'm not familiar with its limitations. (I can see occasions when I would prefer DreamCard--or StackRunner--to building an app. It would be most helpful working with a user during the development stages. Updates would consist only of the new stack without the need to continually carry the baggage of the full application.) But help me out a bit. StackRunner comes in at 3.6 megs, and DreamCard at 2.1 megs. What are the differences and when would one choose StackRunner and when DreamCard? Thanks again for all you do for the Rev community.

I've also added some new stacks, and hopefully there will be more to come in the next few weeks as I get myself organised. I have also changed to using Gmail for all Revolution list emails. I find the threading really good and I like being able to read reply to the list from any computer. If anyone wants an invitation to join Gmail, let me know off-list and I will be happy to send some out. Have fun, Sarah [EMAIL PROTECTED] Sarah, Thanks for the re-design. I know I will have use for the Pending messages manager in debugging stacks with lots of messages floating around. It is good to know what messages are pending, not just when they are sent as with RR's message watcher.

ANN: Line shaper
I have always wondered about the feasibility of a shaper graphic tool. By shaper tool I mean a circular graphic which may be used to nudge a graphic line to conform locally to the shaper. That is, as the circle moves against the line, the line conforms to the circular shape of the shaper. Imagine a string lying of a flat surface. Slide a circular disk into the string. The string will be deformed to the shape of the disk. (Well, not quite. The length of the sting is fixed; the length of the Rev graphic line is not fixed. Instead the number of graphic points is fixed. It might be interesting to try to keep the length of the graphic line fixed.) This works by pushing the graphic points ahead of the shaper. (You can see this by making the Marker Points visible.) This tool works poorly when the graphic points become widely separated. For most purposes, the bezier tools still work best for constructing lines with a complex shape. But some may find the shaper useful in some situations.

OT: Another NPR puzzle
Here is another NPR (National Public Radio) puzzle: From listener Frank Morgan, a mathematician at Williams College. (He also has a puzzle page at mathchat.org.) Think of a word whose meaning you can make plural by adding an A at the start. Start with a very common singular noun, add the letter A at the beginning, and you'll make the meaning plural. What word is it? Note that the meaning is made plural, not the word itself. The straightforward approach is not very fruitful. Listing all words which can be derived by pre-pending the letter a yields 559 words. Hard to find the word satisfying the conditions of the puzzle from so large a list. The best I was able to do was a list of 103 words to choose from. (I realize that that statement is enigmatic.) To save time it is imperative that the dictionary be converted to an array, i.e. for each word (tWord) in the dictionary: put true into dictArray[tWord] The dictionary is compressed in a custom variable--see the Get started button. This is harder than the last NPR puzzle. In the message box run: go stack url http://home.infostations.net/jhurley/NPRpuzzle.rev; It is a large file (370k) so be patient.

OT: Search content of your Rev files
For those of you using OS X 3 and those using OS X 4 but have not been successful with Spotlight, there is an alternative called EasyFind, free and available at: http://www.macupdate.com/info.php/id/11076 To search for Rev file content it is necessary to include (under the light switch icon) either the file extension (.rev) if there is one, or the type code or Rev: 'RSTK' (Be sure to include the single quote at each end.) The later is safer. It will search all Rev files, extension or no. EasyFind is much slower than Spotlight but MUCH more reliable.

Due to some other complexities, I cannot just do a send mouseUp to me in 1000 seconds Rather, I have to wake up every 10 seconds and figure out whether it is time to do the processing or not. The current code is presented below. The interesting thing is that, despite the claim that Rev times are in seconds, and even in milliseconds, the values I'm seeing are in increments of 60 seconds. I flagged a line in the code below. Rather than seeing 60 and then 50 and then 40, etc, I instead see 60 6 times and then 0. Am I doing something wrong? Or, rather, what am I doing wrong? BTW: feel free to show me how I should have written this: it is hugely awkward and could be done much easier in languages that I know better. :) Jon on mouseup local mostRecentFTPTime -- is it time yet? convert the date the time to dateItems subtract field TestFreq from item 5 of it convert it to seconds put item 1 of it into currTime if currTime mostRecentFTPTime then -- show the user how long before next test set the text of field TimeToGo to mostRecentFTPTime - currTime secs to go -- this is the line I'm talking about send mouseUp to me in 10 seconds exit mouseUp end if -- do the FTP stuff here! convert the date the time to seconds put it into mostRecentFTPTime send mouseUp to me in 10 seconds end MouseUp Jon, The information in the variable mostRecentFTPTime is lost after mouseUp is run. To save that data you might want to consider a custom variable, for example: set the mostRecentFTPTime of me to it, and earlier: if currTime the most mostRecentFTPTime of me then Jim ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: resolution of Time in Rev
Jon, I should have pointed out in my previous response that the way to find these problems in the future is to use the RR debugger. If you set a break point at the line: if currTime mostRecentFTPTime then... and if you open the Variable watcher you would see that the variable mostRecentFTPTime is empty on each go around. You would then easily recognize the need for permanence, either using a global or custom variable.

OT: Super-computer studies aerodynamics of the potato chip
This from todays NYT: Once the exclusive territory of nuclear weapons designers and code breaker, ultrafast computers are increasingly being used in every day product design. Procter Gamble used a supercomputer to study the airflow over its Pringles potato chips to help stop them from fluttering off the company's assembly lines. Today the potato chip, tomorrow the Shuttle.

Ask does not put empty into it when Cancel is clicked.
Is this a known change in 2.6? The scrip below functioned as expected in Rev 2.5. When the user click Cancel in response to the ask command the it variable was set to empty. Not so in 2.6. In 2.6 the script behaves differently. When the user clicks Cancel, there is a error response. The ask command does not return empty to the it variable--I'm not sure what it is. It shows empty but charToNum return the zero character. From the Docs: If the user cancels the dialog, the it variable is set to empty and the result function returns cancel. on mouseUp ask What field to save? --User clicks Cancel if it is not empty then --Debugger steps into this line even --though Cancel was clicked. put it into temp1 --Shows empty put chartonum(it) into temp2 --Shows 0, i.e. zero put the result into temp3--Shows empty but should be cancel put field it into tContents --Error message else put field 1 into tContents ask file Put where? if it is not empty then put file: it into tFileName put tContents into url tFileName else beep exit mouseUP end if end mouseUp There is a work-around. Test the the result not it, i.e. use: If the result is not empty.
