QUESTION
I'm trying to build a Flutter Web version of the threejs Periodic Table Helix view (see here: https://mrdoob.com/lab/javascript/threejs/css3d/periodictable/ and click on "Helix")
Currently, I place all the element tiles in a stack, and position and rotate them with matrix transformations. See below code:
...ANSWER
Answered 2021-Mar-04 at 16:08So I found a solution. It's not perfect, but it works so far.
The idea is to use a Flow() widget. In the children widgets, where I'd normally build them, I instead stored their transformations in a map. Then, in the flow delegate function, access these transformations, calculate the z coordinate of each widget after transforming (row 3, column 3 (1 indexed) in the transformation matrix). Sort the widgets by z coordinate, and then paint them on screen in that order.
Here is the code for the same:
The part with the root Flow widget:
QUESTION
Thank you for your help in advance!!
I've created a class to which I pass the name of an array as an argument.
...ANSWER
Answered 2020-Apr-11 at 13:18You're storing a dangling pointer.
Not an array; a pointer.
By the time you try to use it, the array (which was a local variable in FillPeriodicTable()) is dead. Gone. Buried. Turned to dust long ago.
If you want the class objects to contain arrays, then make them do that thing, preferably by storing a std::array.

I'm strugling with generating periodic table in HTML from information given in this.periodicTable[] and rendering it later, as you can see in code below. How can I make it work?
Firstly i have made it by hand (all in render() section written in HTML), but later I found out that generating it would be better idea. Everything worked until i switched to generating html istead of writting it. I also would like to use periodicTable data in other parts of website so this one is necessary

QUESTION
I need to output the number of elements from a dat file. The number of elements needs to be 118 but I get 0.
...ANSWER
Answered 2019-Oct-22 at 20:35When I run the sample class it seems to work correctly for me, so I assume there is and issue with the periodictable.dat file.
With a test periodictable.dat file filled with the following:
110 T 200.00 Test
300 A 100.18 Again
I get the following output:
Periodic Table
2 elements
If there was a formatting error in the file you would receive a mismatch exception. So I would
- Check your file is not empty as this would cause the while condition to be false.
- I would also add what your current file looks like in your question :)

I am creating a periodic table and I have created a dictionary in the Home Controller called dictionaryOfElements which has element's atomic number as key and element's atomic number, symbol, name, and weight as values. I need help in displaying all the values of a dictionary to a View from ViewModel.
Below is the Model I created:

QUESTION
I'm trying to make a program that will allow the user to input either a name or symbol of an element from the periodic table, and will then output some data about that element. So far I've managed to get the user to be able to input either a name or a symbol and have it output correctly, but if the user inputs something wrong then the code doesn't output anything, and will stop accepting an input of a symbol and only accept an input of a name. I would like to know how I would be able to break out of the loop and tell a user that their input is invalid only after the input has been checked against every item in the enum, since my current solution doesn't work. I'm new to Java, so a simple explanation as to how and why would be greatly appreciated.
...ANSWER
Answered 2018-Dec-01 at 20:35Assuming I understand your question, I would add the logic for parsing Element(s) to Element. You can create Map(s), one to symbol and one of name to corresponding Element instances and then invoke them in whichever order you choose. Like,
QUESTION
I've been working on a program that will take the user's input of the name or symbol of an element in the periodic table and then output some facts about that element. After quite a few questions on here I've gotten to the point the program stores all the data correctly, outputs it in the way I want and can accept an input of both the name or symbol. The problem I'm having now is that the breaks I have inserted into a loop are not actually breaking from the loop, and I'm really not sure why. The program will just keep on asking for an input even if it received a correct input. In addition, if the user inputs a symbol rather than a name the program will repeatedly tell the user that their input was invalid before finally outputting correctly (and then restarting the loop rather than breaking as it should). I'm new to Java, so if anyone could help me fix either of these issues and explain why the problem occurred and how they fixed it fairly simply I would greatly appreciate it.
...ANSWER
Answered 2018-Dec-01 at 18:12The problem is that the break's are within the for loop, so it only breaks to for loop. If you want to break the do-while loop you can use a label:
QUESTION
I couldn't really think of how to phrase the question, but I have a fairly simple program that will ask the user to input an element from the periodic table and then will output the symbol, group and atomic mass of that element. Currently it will only accept an input of the name of the element, and I'm trying to make it accept an input of the symbol too, but I don't know how to do that. For example, at the moment if the user inputs "Iron", the program will output correctly, but if they input "Fe" it will not work. I want the input of "Fe" to work as well. I'm very new to Java, so a simple explanation as to how and why would be greatly appreciated.
...ANSWER
Answered 2018-Dec-01 at 16:10The collection Element.values() contains all the values of your enum class.
After the user gives input, loop through this collection and check the symbol property to find the element.
QUESTION
How do I determine if a WPF page is still in the navigation history of WPF frame and then navigate back to it?
Summary:
My WPF application uses a single MainWindow containing two Frames one for menu layout and the other for display content. I am using MVVM pattern with content displayed as WPF pages as views with as little code as possible behind each view/page.
The content frame (shown in red) has a NavigationUI visible.
XAML:
Here is typical code to create WPF page and display it in the main window from a static helper class:
...ANSWER
Answered 2018-Nov-24 at 15:43Pages are rarely used in commercial apps. As I understand it, they were really intended for xbap ( wpf in a browser ). It's much more usual to have usercontrols hosted in a contentcontrol. In which case there are two commonly used alternatives
1) View First. Hold a dictionary of usercontrols keyed by type. https://gallery.technet.microsoft.com/WPF-Navigation-Basic-Sample-11f10c74
QUESTION
Continuing on from this post I've been looking into and messing around with enums a bit, and now I've managed to create an enum that holds the values I want and outputs them in the way I want, now I'd just like to know how I could get the same output but for a single item rather than every item. Again, I'm very new to Java so a simple explanation as to how and why would be greatly appreciated.

Answered 2018-Nov-16 at 00:56You can use the valueOf method passing in the user input to retrieve the enum:

Install PeriodicTable
You can use PeriodicTable like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
