QUESTION
A part of my form contains QGroupBox
(Status Box
) with 4 child QGroupBox
es arranged in a grid layout (2x2). Two bottom QGroupBox
es (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 QGroupBox
es (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 QGroupBox
es 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 QGroupBox
es. As a result spacing between QCheckBox
es 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 QCheckBox
es 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 QGroupBox
es 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)?
ANSWER
Answered 2021-Jun-15 at 17:18Items will be aligned if both QGroupBox
es have same count of children and each row have at least one child with Expanding
vertical policy. Instead of spacer use QWidget
I removed unrelated widgets and reduces number of rows to 4 for demonstration purposes (less xml).

QUESTION
Is there a way (except looking at implementation and docs) to determine when new() in rust allocates on stack or heap?
Ideally I'm looking for a way to determine this when writing source at a glance. For example trait or parameter that can be added restricting whether heap allocation can take place.
...ANSWER
Answered 2021-Mar-02 at 12:20Functions named new()
in Rust are not special in anayway. So no, you cannot easily determine if something returned by such a function owns any heap-allocated data. Even for std::default::Default
trait implementations there is no restriction nor convention which prevents the default()
method from doing heap allocations, nor is it usually documented.
QUESTION
Working with type stubs, I'm wondering if it's possible to express a type in Python that allows you to type this correctly for any number of arguments:
...ANSWER
Answered 2021-Jun-10 at 12:09TLDR: @overload
is currently the only viable way to annotate some level of variance. PEP 646 -- Variadic Generics is a draft proposal to enable proper annotation of variadics.
The correct approach to annotate *args
is to decide on some level of supported "variance length", and explicitly type this using @overload
. Notably, explicit parameters must be positional only β they must be either __anonymous
or positional, /
. A final catch-all variadic @overload
handles the case of more arguments.

QUESTION
If I run the code below, my Global Environment in RStudio tells me the dimensions for x2 (num [1:10, 1:10, 1:10]). But for x1, it only says "large array (1000000 elements, 7.6 Mb)".
I want to see the array's dimensions at a glance even for large arrays. (I know I can run dim(x1)
to get the dimensions, looking for an "at a glance" solution with RStudio...)
Is there a way to get RStudio to treat even large arrays like it does with smaller arrays?
EDIT: It does show the dimensions if I click the small blue error beside x1, but I'm working with many large arrays and adding/removing from my environment. I am hoping to make it show the dimensions by default.

QUESTION
I'm trying to figure out how to parse S-expressions in C on my own, in order to store data and code for my own rudimentary Lisp (written as a learning exercise, not for production).
Before explaining my code and my reasoning, I should explain that all I know about S-expressions is the introductory section of the Wikipedia article on it, and the occasional glance at Common Lisp code, so the naming of my structs and variables may be a bit off.
My language of implementation is C, and before I defined any functions I created the following structs:
...ANSWER
Answered 2021-Jun-06 at 15:05Don't use void*
. Use a union
. That's what union
s are for.
In this example, I use an "anonymous union", which means that I can just refer to its fields as though they were directly inside the Atom struct. (I changed the spelling of names according to my prejudices, so that types are Capitalised and constants are ALLCAPS. I also separated the typedef and struct declarations for Atom, in case Atom turns out to be self-referential.

I try example in this topic https://github.com/DevExpress-Examples/XPO_how-to-create-an-xpclassinfo-descendant-to-dynamically-build-a-persistent-class-structure-e1729

I have run 3 regressions with rdrobust, and would like to print some of the values (not all of them in a table, so that each model has a column and the results can be compared side by side.
I tried with stargazer but with no success, same thing goes for modelsummary.
This is what my regression code looks like:
...ANSWER
Answered 2021-Jun-03 at 15:03I asked for clarification in a comment, but here is my best attempt at guessing what you want in the table:
- Multiple models side-by-side
- Model estimates
- p values in parentheses below estimates
- Kernel type at the bottom of hte table
- Bandwidth selection at the bottom of the table
To achieve this, I only modified your glance.rdrobust
method, and I used the statistic
argument of the modelsummary
function.
Load libraries and define custom tidy
and glance
methods to extract information (see documentation) from rdrobust

QUESTION
I use a spreadsheet to prioritize workflow for my team. Certain cells highlight depending on how close we are to cycle times. There is a start date, a tentative finish date, and a discharge date.
A blank discharge date cell turns red if: start date is not blank; tentative is not blank; and today's date is within five days of the tentative date.
Some of my team member have the habit of writing their dates with periods (mm.dd.yyyy). Excel of course does not recognize this as a date. BUT it does know that the 'tentative date' cell is not blank. As a result, even if today's date is equal to the tentative date, the 'discharge date' cell does not turn red. This is taking away from the utility of this sheet, as it is intended to be info at a glance, where a glaring red cell lets one know, "Oh shoot! I need to focus on that task as a priority."
I'd like for the start date and tentative date cells to go red if the date is not the desired format (mm/dd/yyyy).
Formula and condition in S1:
S1 fills red if
=AND($P1-TODAY()<=5,COUNTA($S1)=0,$M1<>0,$P1<>0)
...ANSWER
Answered 2021-Jun-03 at 01:23In the same way that you can conditionally format the output as red with your supplied formula above, you can conditionally format the inputs (start date and tentative date) if they do not match your criteria.
One idea is to use something like =SEARCH(".", A1)>0
as the criteria for the format (if the incorrect input always comes in some variation of dd.mm.yyyy, and assuming the start of your range is in cell A1).
Here are the steps to do so if you did not create the original rule:
- Highlight the ranges of the start and tentative dates
- Go Home->Conditional Formatting->New Rule->"Use formula to determine which cells to format"
- Enter the formula above (where you are sure to remove absolute references)
- Go Format->Fill->Choose Red and hit okay
