Initial error when trying to use @iconify-icons/cryptocurrency with next.js and typescript (it happens only when in typescript).

I am working on extending a Vue.js frontend application. I am currently inspecting a render function within a functional component. After looking over the docs, I had the current understanding that the render function within the functional component will return a single VNode created with CreateElement aka h. My confusion came when I saw a VNode being returned as an element in an array. I could not find any reference to this syntax in the docs. Does anyone have any insight?

A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.

And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).

This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.

If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).

I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.

What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?

I've read a number of questions on this same error but couldn't understand whats happening in my case. On the other questions this error is caused by an object being used as a React child or caused by more than one prop attribute being passed.

I'm trying to set formik and yup to validate a Day Field according to a Month Field, both using react-select, in such way that if the month is February then the max day allowed is 29. Just that...

I've managed to reproduce the error in a Codesandbox: https://codesandbox.io/s/formik-yup-reactselect-rmd9f?file=/src/App.js

If you select the Day 29 and any month, then it works, but if you select day 30 and February then this error appears and I can't find out what's wrong:

Uncaught Error: Objects are not valid as a React child (found: object with keys {value}). If you meant to render a collection of children, use an array instead.

The code is:

I have a two sets of data in database one is date and one is time. I display my data in calendar. I made one post request when user choose the date, that time will be selected for the user. I want to make one helper function when user's choosing time will be over I want to show them alert in front-end that "Your selected time expired!". I am using date-fns for date validation.

This is my code so far:

I'm using BufferGeometry to handle meshes with lots of vertices, faces and normals, which I supply via TypedArrays. During rendering, the Scene and its Mesh is constructed without any warnings or errors in the console. With BoxHelper I've constructed a Bounding Box around the mesh.

Now the strangest thing happens: Although the Bounding Box is perfectly correct, the faces/vertices are cut off somewhere in the middle.

To see what I mean, here is the comparison of two models rendered with a python script (left) and rendered with Three.js (right):

The code I've used for this task can be found here in this pastebin. Any help is highly appreciated.

hello i'm using css counter to display the number of div that have a specific class inside a section but i don't know why the result of my code is alwase 0 this the code

I'm working on a Project where I have a lot of decimal fields in every model and want to put comma all of them. I can use helper mutators or PHP number_format() while fetching. The problem is I have to do it for every field.

Is there any simple solution for this??
