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.

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

Hi Gerald,

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

Attendees in the daily study group had asked about the palette used to delete outputs during presentation. DeleteAllOutputPalette is now present in the Wolfram Function Repository. https://resources.wolframcloud.com/FunctionRepository/resources/DeleteAllOutputPalette/

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]
    ]
   }
  ]
 ]

I would like to develop UI's that clients can use with Wolfram Player. From the class yesterday it seems that DynamicModule could be used in this way. Is this correct?

ETA: I would like to keep my functions proprietary, i.e. the client would not be able to see the code.
POSTED BY: Tom Blanton

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.

I am trying, without much success, to set a local DynamicModule Variable (x) when a global variable (y) is changed :

y = 1 ;

DynamicModule[{x},
 Dynamic[y; Print["called"]; x=100, TrackedSymbols :> {y}]; 
 Dynamic@x,
 Initialization :> (x = 3*y)]

Where am I going wrong?

Is it permissible to Overlay a control onto a graphic?

For the "Car Game" I created a background image as a graphic object and the "start"/"Stop" controller

background = Graphic[...] control = ... which toggles as in the car game demo,

But the control can't be used when these are packaged together using 

Overlay[{
  background,
  control
  }, Alignment -> {Center, Bottom}]

Thanks.
POSTED BY: John Burgers

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: Jayanta Phadikar
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
 ]

How would you set up two columns where the left column is text and the right column is Mathematica commands such as In/Out. This is format was used by S. Wolfram in his Mathematica Book 4th edition.

Jorge,

I believe the differences you are seeing are because the visual appearance of controls matches the default appearance of controls in the underlying operating system. The one on the left is Mac OS, the one on the right is Windows. I don't think there is an easy way to make them look identical.

In few examples from the tutorials in Windows 10 I have a couple of appearence issues: For example in the figure below enter image description here

The controls are truncated.

In the next simple command the x symbol at the left appears very small. enter image description here

Both examples are at 100% (zoom) magnification level. Obviously there is a matter of scaling in a laptop screen. All the values at the preferences are in the default values.

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

The approach suggested by Mr. Choi is correct.

The standalone version of the built-in LAB color palette can be seen using:

CellPrint[FrontEndResource["LABColorValueSelector"]]

This particular palette works by replacing the selection, and is thus hard to integrate with a Manipulate.

It is possible to emulate the built-in LAB color setter using top level code, but that would require some work.
POSTED BY: Jayanta Phadikar
POSTED BY: James Choi

I am wondering is there a way to vary what type of color setter is presented to the user with the Manipulate function. For example, is it possible to use a LAB Color setter instead of the default color selector in the Manipulate function? enter image description here
