QUESTION
As you can see from the image 2 QVBoxLayout looks bad so how can we design it so that both takes 50% of the QHBoxLayout size each.
As you can see combo_test11(QComboBox) and txt_test22(QLineEdit) both does not look aligned properly. both widget should be equally stacked/aligned so how can we design it .
I cannot add any fixed width since I need the whole box and the widgets to be responsive so any fixedwidth solution is not acceptable
Below is my implementation :

Answered 2022-Mar-24 at 21:00Whether you do it in Designer (recommended) or in code, you'll probably want to play with the stretch parameters. To make this particular form look good, a 1:2 ratio of label:control isn't bad.
Also, you probably want the label text to be right aligned. You can do this in HTML markup or in the alignment property.
I modified your horiz_layout function to have stretch:

ANSWER
Answered 2021-Dec-02 at 18:12The javadoc in AuthenticationPrincipalArgumentResolver says the following:
Will resolve the CustomUser argument using Authentication.getPrincipal() from the SecurityContextHolder. If the Authentication or Authentication.getPrincipal() is null, it will return null. If the types do not match, null will be returned unless AuthenticationPrincipal.errorOnInvalidType() is true in which case a ClassCastException will be thrown.
So you should make sure that the Authentication.getPrincipal() type is ExpiringUsernameAuthenticationToken.
Debug your application and see which type returns from SecurityContextHolder.getContext().getAuthentication() and from authentication.getPrincipal()
QUESTION
I'm trying to create a circular progressBar with timer function in my UItableviewCell class. I have created a custom class timer, and I am using Jonni's progressBar template (Credit to Jonni Åkesson) from - https://github.com/innoj/CountdownTimer.
The only noticeable difference between my code and source template is that I am adding the Custom ProgressBar class UIView programmatically whereas the source template used IBOutlet to connect to the Custom ProgressBar Class.
My goal is to ensure that the CAShapeLayers (both actual and background layers are shown as per below image - Source: https://www.youtube.com/watch?v=-KwFvGVstyc
Below is my code and I am unable to see both front CAShapeLayer and background CAShapeLayer. I am suspecting a logical error when I initialize constant "progressBar".
Please advise if it is possible to utilize the Custom ProgressBar Class, instead of re-writing the entire code.

I have an issue when in try generating mesh around a spline.
Everything is good but at random point on the spline the mesh is "twisted". Some of triangle are shifted (cf picture)

And the code who create the mesh. I do not start filling the array at index 0 because i generate the cap of the "tube" before (i can share the code if needed)
...ANSWER
Answered 2021-Nov-24 at 22:41The problem is that only knowing the current position and direction of the pipe isn't enough.
To illustrate, start with two identical pipes lined up going forward, with the top marked in red and the bottom marked in cyan with paint. Bend pipe 1 upwards, then to the right, then back down, then to the right. Bend pipe 2 downwards, then to the right, then back up, then to the right. Both pipes will end up at the same point and direction, but the red and blue sides at the end are in different positions:
(also applies to round pipes, of course)
If you don't account for this ambiguity and always treat the "top" as red, you would have to have points in the pipe where the red paint "twists" around your pipe. The same principle is what is happening to the edges & faces of your mesh.
To account for this, you can use the power of quaternions to calculate where the "first vertex" on the current ring corresponds to where the "first vertex" should belong on the previous ring.
The position of this "first vertex" we will call the "index direction". We can think of this direction as the direction of our "red paint". In reality it will be the first vertex for the ring at that location in the spline. So, the same thing your perpendicularVect did!
So, you can begin the pipe by finding any valid index direction. For the purposes of getting rid of these twists, it doesn't matter how this is found. Cross product with a constant parameter works great, just be sure to handle colinearity.
Then, at each following step, find the minimal rotation which rotates the previous direction of the pipe to the new direction. Quaternion.FromToRotation does exactly this. Then, apply that rotation to the index direction to find the new index direction.
Regardless of the step you are on, once you have your index direction, you can proceed as you were as if it was your perpendicularVect. Rotate it around the pipe's axis to find the other points in the ring, and connect adjacent points to each other. Then, continue to the next step.

QUESTION
I am working on a game map, that is made up of a hex grid. Currently I am saving the center points of each element to a list when they are generated. I want to have the tile the current mouse is over, to be highlighted. I have it working by taking the mouse position, and using the distance formula, and loop through each element to find the closest element to the mouse.
CENTER LIST is a list of centerpoints for each hex tile.
...ANSWER
Answered 2021-Sep-30 at 16:42Keeping a list of central points probably isn't the best way to represent hex tiles, and using a hex coordinate system is probably the most appropriate way of solving the problem (see the comments below your post for good resources to get started).
Should we keep to your list of center points approach, however,
a good way to speed up this kind of computation is usually to use the numpy library, which was built with scientific computing in mind and comes with extremely quick built-in functions:
