Rohit, Thanks. Gerry

I'd like to use Manipulate to show a dynamic control variable's name and value in a larger font size. The following code yields the name of the scoped variable for "a" rather than its value, for example "a = Dynamic[FE`a$$189]". How do I fix this code so that the value of the dynamic variable appears with font size 20?

Manipulate[
 Grid[{{Style["a = " <> ToString[Dynamic[a]], 20]}, {ContourPlot3D[
     x^2 + y^2 + a z^3 == 1, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}, 
     Mesh -> None, ImageSize -> Medium]}}], {a, -2, 2}]

Hi Gerald,

You were close.

Manipulate[
 Grid[
  {{Style["a = " <> ToString@a, 20]},
   {ContourPlot3D[x^2 + y^2 + a z^3 == 1, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}, 
     Mesh -> None, 
     ImageSize -> Medium]}
   }],
 {{a, -2, Style["a", 16]}, -2, 2}]

Also increased the size of the label for the control.

John again,

No need to answer. On viewing the last session recording I learned callKernel is a dummy variable.

Thanks for the very useful / helpful course materials.
POSTED BY: John Burgers

I'm having trouble finding further information on the use of "callKernel" in the Wolfram documentation. I'm hoping someone can direct me to further my understanding or provide an explanation so that I understand more how it functions in examples such as in Session 13 Tip and Tricks for Effective UI design example of a Button disabled until computation finishes ...

DynamicModule[{enabled = True},
 Button["Print",
  enabled = False;
  Pause[2]; Print[TimeObject[]];
  enabled = True;
  ,
  Method -> "Queued",
  Enabled -> Dynamic[callKernel; enabled]
  ]
 ]
POSTED BY: John Burgers

TimeConstrained seems not to work when implemented in the Button functionality.

  • Correctly understood?
  • Is there a work around?

Thank you in advance and best regards Pål L

Is there a way to verify that my quiz results have been recorded?
POSTED BY: Tom Blanton
POSTED BY: vincent feng

Hi Tom,

As long as you see a passing score after hitting "Get Results", your score has been sent to a Databin for review by the Wolfram U team. Quiz scores will be reviewed the week of Oct. 4th and certificates sent shortly thereafter. If you do not receive your certificate, please send an email to wolfram-u@wolfram.com, we can pull the data and double check at that time.

Hi Gerald,

I see a couple of typos. Dyanmic[input] should be Dynamic[input], and BaseStyle -> BackGround -> White should be BaseStyle -> Background -> White

PaneSelector evaluates its arguments before the selector is rendered, they are not re-evaluated when a selection is made. e.g. the random values do not change

DynamicModule[{x = 1}, 
 Column[{SetterBar[Dynamic[x], {"Don't press this", 1, 2, 100, "Hi there"}], 
   PaneSelector[{"Don't press this" -> "I said DONT PRESS !!!", 
     1 -> RandomInteger[10], 2 -> RandomReal[], 100 -> "You Pressed One Hundred", 
     "Hi there" -> "What is your name ?"}, Dynamic[x]]}]]
POSTED BY: Rohit Namjoshi
POSTED BY: Artin Hatzikioseyian

Use the second argument of Dynamic:

DynamicModule[{x = 1},
 Column[
  {
   SetterBar[
    Dynamic[x, 
     If[# == "Don't press this", Speak["I said DONT PRESS !!!"]; 
       x = #, x = #] &],
    {"Don't press this", 1, 2, 100, "Hi there"}],
   PaneSelector[
    {"Don't press this" -> "", 1 -> "One", 2 -> "Two", 
     100 -> "You Pressed One Hundred", 
     "Hi there" -> "What is your name ?"}, Dynamic[x]
    ]
   }
  ]
 ]

Question: Today you pointed out that ImageSize -> Automatic helps speed up slow interfaces. Could you please explain why?
POSTED BY: Zbigniew Kabala

Wrapping the contents with Dynamic and setting ImageSize->Automatic make the contents evaluate only when the particular tabs are clicked. Without these settings, TabView or PaneSelector evaluates all the contents before displaying. Thus the settings help in reducing the initial loading time.

Yes DynamicModule is in general supported in the Wolfram Player. Please see the difference between the Free Player and the Player Pro/Enterprise CDF though, for a comparison of all the supported features.

We will discuss encoding of packages, making the functions ReadProtected etc. for securing the code in Session 10 - Deployment. If your interface is small enough, you could deploy the interface and need not keep code in any separate package. Once again, more about deployment practices are coming in Session 10.

Yes, it is possible by using the third argument of Overlay.

Here is an example from the documentation (ref/Overlay#53834658):

Overlay[{Slider2D[], Graphics[{Opacity[.2], Disk[]}]}, All, 1]

POSTED BY: John Burgers

Yes it seems that the controls from only one layer can be activated. You can however use Row/Column/Grid in that layer for keeping multiple controls.
POSTED BY: Jayanta Phadikar

Where should I put the Dynamic to control the appearence or not of the frame in this toy manipulate example:

Manipulate[
 x,
 {x, 0, 1},
 {{frmd, False}, {True, False}},
 Paneled -> frmd
 ]

It would be better if you did NOT begin the session with some survey question that blocks the session from opening up on my computer. I am working on the computer while waiting for the session to begin and depending on the sound of the audio to let me know when the session has begun. That is the whole point of signing in early, and the survey question defeats that purpose.

POSTED BY: Raymond Low

Hi Raymond,

Sorry to hear you faced some issues with the webinar session today. We do use poll questions to allow our attendees to interactively respond during the study group. But they should not interfere with the webinar itself in anyway or prevent it from starting up. If you run into the issue again, please email us at wolfram-u@wolfram.com and we can try to troubleshoot it.

Hi Charles,

I think what you are looking for is an undocumented function MakeBilateral from the AuthorTools package. Check this thread on MSE.

One of the comments in that thread

MakeBilateral is to make documents or parts of documents like the style of Wolfram's old printed "The Mathematica Book", with explanatory text alongside Input/Output cell pairs

Dear Friends, how can I obtain the same type of sliders and light gray color in the final graphic if I'm using the same code? Do I need to change some initial setting?

Many thanks.

POSTED BY: Jorge O. Garcia L

Yes by default the appearances are OS dependent. We can set a generic appearance which should be independent of the OS:

Style[Slider[Dynamic[x]], ControlsRendering -> "Generic"]
POSTED BY: Jayanta Phadikar

Thank you for your reply. I think in the option inspector should be "somewhere" an option for the default FontSize to be set at 12 globally or for a notebook.

Thank you everyone for your enthusiastic participation in this week's sessions. I hope that you have been enjoying and finding the sessions helpful.

In this week, we covered some fundamental concepts of dynamics and Manipulate.

In the next week, we will discuss more about certain pragmatic concepts related to the development of User Interfaces and look at several User Interface examples.

Our apologies for few things here and there not working properly in the notebooks. We are making the corrections and will make an updated set of notebooks available to you at the end of the series.

Hi Everyone,

Just wanted to confirm Quiz 1 should be working as expected. Our apologies for the issues you faced with the quiz last week.

Also we'd like to request that you not post the link to the quizzes here in the public forum. We've created the quizzes specifically for our study group attendees. But we are happy to discuss any questions you may have about the quizzes, here.

Thank you, Abrita

On slide 10 of today's presentation, Session 3 - Dynamic Fundamentals I, a correction was made to the following expression:

Control objects:

stop = 1;

Dynamic[
 If[stop == 0,
  Button[Style["Start", 20], Background -> LightGreen, ImageSize -> {80, 40}],
  Button[Style["Stop", 20], Background -> LightRed, ImageSize -> {80, 40}]]
 ]

To make it work as intended, stop==1 and stop==0 were inserted, but I haven't been able to make the correction properly. Could you please help?

   ImageSize -> {80, 40}]]
