QUESTION
I created a class that helps me to show a 3D model using A-Frame. In this class, there are some spheres created at runtime ad inserted into the scene. I'm trying to add an event listener (I have to show a message when those spheres are clicked)
Here is the code:
...ANSWER
Answered 2021-May-06 at 16:40Using the setAttribute("pointer-handler", "")
approach is absolutely valid and a correct way of doing what you want to achieve.
I think it may be the click
event that's causing problems. I suggest you replace it with mouseup
and mousedown
events.
Also make sure you can indeed fire the events - you need a cursor attached to your camera
Working examplerun in full screen (top right corner after running snippet to see the whole scene - close is also in the top right).
You can add new elements by pressing the button in the top left. See how click sometimes is fired and sometimes not at all.
QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I'm doing some final cleanup in my code for straggler functions. My output pane is taken directly from the out of the box OutputWnd.cpp
created by the MFC wizard. When you right click on the output pane with the 3 tabs it creates, the context options are copy/clear/hide. I have copy and clear working. But the issue is the Hide
. When clicked, it drops into the function void COutputList::OnViewOutput()
and I've debugged it to verify it drops into it.
Here is the function:
...ANSWER
Answered 2021-Apr-18 at 20:46Yes, you're right.
If we create a simple project (based on the "MFC App" template with "Project Style" as "Visual Studio" and "Visual Style and Colors" as "Visual Studio 2008"), then
even the out of the box solution doesn't work.
Why is this happening?

members are created
QUESTION
I am working on assigning random priorities (i.e. high, medium, low) to a list for a ServiceDesk assignment.
Before that, I was wondering how to go about storing (and printing) an array in said priority queue. This is currently what I have.
*UPDATED CODE
...ANSWER
Answered 2021-Apr-18 at 02:33Sounds like you are asking for help on how to get started. You are asking for help on learning to learn. Here is how I would approach your problem:
Apparently you are supposed to use a priority queue.
- Write a tiny program that makes a priority queue and stores strings into it, then prints them out.
- Define a class and store instances of that class into the priority queue instead of strings.
- Modify the sort criteria on the priority queue and notice that the printed sequence changes according to the sort criteria.
- Write a function that creates one class instance with random values.
- Write a function that creates all 100 class instances.
- Declare victory.
QUESTION
I would like some help please, you see I had to determine in exercise 6, if the the array included the name "waldo" and if my function would past the tests, it did and the console logged true for both tests. Now in exercise 7 it wants me to do this again, determine if the array contains "waldo" and if it does or doesn't my function should past these test. My issues if I tried so many different scenarios and I keep getting the console to log false for both tests or give me an error message "arrayOfNames" is not defined. I'm trying to use the hint and just call my containsWaldo function to no success. Any idea of what I'm doing wrong here, I copied in the questions for both exercises to make it hopefully more clear. Thank you in advance.

QUESTION
I'm trying to perform a parallel operation on several chunks of strings at a time, and I'm finding having an issue with the borrow checker:
(for context, identifiers
is a Vec
from a CSV file, client
is reqwest and target
is an Arc
that is write once read many)
ANSWER
Answered 2021-Mar-02 at 22:35Your issue here is that the identifiers are a Vector of references to a slice. They will not necessarily be around once you've left the scope of your function (which is what async move inside there will do).
Your solution to the immediate problem is to convert the Vec<&[String]>
to a Vec>
type.
A way of accomplishing that would be:

QUESTION
ANSWER
Answered 2020-Dec-10 at 20:49I would suggest that you would first just assign a new group name to the selected questions, and then go through all the questions to see what needs to be updated:
- The minimal value for
date
should be determined for each group, and the size of the group - Following the order of increasing minimal
date
, these groups should be reassigned a name with increasing suffix, or "no-group" if their size is 1.
So you would still sort, but just temporary, without affecting questions
itself.
Here is how that could be coded:
