I am new to styled components. I am trying to change the flexDirection in media query but my inline styling row
seems to overlap with media query styles.
Code Link: https://codesandbox.io/s/hungry-minsky-npubu

I am not sure how to handle this issue. Can anyone please help me with this?
Thanks

QUESTION
I'm using react and I'm trying to create a footer element, that displays some information on one side of the screen. When the footer is hovered I want it to move to the other side of the screen in order for whats behind it to be visible.
A good example of this is the loading footer of chrome. when you move the mouse over it, it moves to the right side (and when you move out of it, it returns to the left again).
I'm currently struggling to make it so the footer ishover events are working and at the same time whats behind it is still clickable. The problem occurs because if the footer has pointerEvent: "none"
the hover event doesn't work, and if the footer doesn't have pointerEvent: "none"
then a button behind it isn't clickable...
I've created a minimal codesandbox to recreate the problem.
Thanks a lot in advance :)

QUESTION
I have a calendar app that renders its events with an array of objects:
...ANSWER
Answered 2020-Dec-05 at 05:30I think that that console.log
is missplaced, you shouldn't be calling that function inside an array assignment. And even if you call it below the setEvents function will not give you the title because the set function of the useState
is asynchronous. Also I think you are not doing right the assignment of the events into your array.
In this line:
setEvents([{ ...events, title: e.target.value }, console.log(events.title)])
You are spreading the events inside a new array and then adding the title, leaving you with a structure similar to this:

I am trying to write a few simple tests that the headers and data I want to render are showing up as expected. I created a repo - https://github.com/olore/ag-grid-testing-library to reproduce. The table looks as I would expect when opened in a browser.

attribute on the element.
QUESTION
I've created a simple draggable component. I'm using the react-swipeable
library but my question is about any event which repeatedly and in quick succession updates useState
.
With the console.log
in onSwiping
I can see that the function is called many times per second, which is what I need to update the position of the component. This works however is there a performance issue with calling setSwipeX
so frequently?
The entire component will re-render very fast as it's dragged. Is this OK or would it be better to just update swipeX
without re-rendering the entire component, and is this even possible?
ANSWER
Answered 2020-Sep-06 at 04:44I'm not an expert when it comes to performance, but I have implemented a couple of weeks ago a component that lets you swipe down page component. It was very similar to what you were doing, but vertically. First time I tried to do so with useState, I had no issues on my Pixel 3a. But when I tested it on Nexus 5x, it wasn't smooth at all. When I changed the logic to work with useRef instead of userState, it felt much smoother. Something like this:
QUESTION
I'm using the package react-transition-group, I have tried using the nodeRef props on the CSSTransition component, and added a wrapper on my component but I still get the warning regarding findDOMNode.
Here's the code:
...ANSWER
Answered 2020-Jun-04 at 10:12There are actually two distinct findDOMNode
warnings in your CodeSandbox demo:
When you first add or remove an entry, which originates from the direct usage of
react-transition-group
forTimesheetEntry
.When you save your timesheet, which originates from the indirect usage of
react-transition-group
through Material UI'sSnackbar
component.
Unfortunately, you have no control over the latter, so let's fix the former; you're managing a list of transitioning TimesheetEntry
components, but to correctly implement nodeRef
, each element needs a distinct ref object, and because you cannot call React hooks within a loop (see rules of hooks), you have to create a separate component:

QUESTION
I have a Form that has a group of checkboxes, Radio buttons and a Button.
Each time I update the value of a checkbox or radio button it dispatches an event that updates my state. I can see this state by clicking my button component:
However, I can't seem to access my state the same way in the parent container by adding the same code snippets as it just returns undefined, this is the same logic that I have inside my Button component, so I'm not sure why it's not working.
I'm clearly doing something wrong, but I'm not sure what. How do I go about accessing my state
from within the parent container?
I also have a working example here: https://codesandbox.io/s/elegant-minsky-0i4yx

...ANSWER
Answered 2020-Jan-12 at 19:58tl;dr Upgrade to PyTorch 0.4.1
Notice that DGL requires PyTorch 0.4.1 and you are using PyTorch 0.4.0. If you take a closer look, you'll see that as_tensor
was proposed in 30 Apr 2018 and merged in 1 May 2018. You'll also see that PyTorch 0.4.0 was released before that on 24 Apr 2018, whereas PyTorch 0.4.1 was release after on 26 Jul 2018. In fact, if you take a look at the changelog of the 0.4.1 version, you'll notice a new operator being announced: torch.as_tensor
