QUESTION
I am trying to get the best combination to reach the best R Squared and P value. In this case, I have 6 columns to run the code, but I have the R-Squared and P values just for this combo ([col0, col1, col2, col3, col4, col5] vs [col6]). I want to test all the possible combinations, something like:
[col0] vs [col6]
[col0 + col1] vs [col6]
[col0 + col1 + col2] vs [col6]...
Is there any way to automatize this? So I dont have to run all possible combinations on hand.

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
I'm creating 2 pages (Summary and Cycles pages) using react.js
.
On the Summary page, there is a column named CN
that every item links to the Cycles page.
Summary page has a path /route/summary/location=abc
and Cycles page has a path /route/cycle/location=abc/deviceId=4410
For example, if I click the value from CN
column in the first row of the table inside the Summary page, I will be redirected to the Cycles page with the path /route/cycle/location=abc/deviceId=4410
.
In the Summary page, I use https://github.com/react-bootstrap-table/react-bootstrap-table2 for the table component and I use a columnRenderer
function inside columns.js
to render a custom item inside the table like this one:
How can I put the pathname
(example "abc") to a Link component inside cnColumnRenderer
function in columns.js
?
Summary page with the path: /route/summary/location=abc
Cycles page with the path: /route/cycle/location=abc/deviceId=4410
Error because of invalid hook call while rendering the Summary page
My Code:table code inside Summary page (inside Summary.js):
hint: focus on columns
variable from './columns' and its implementation
ANSWER
Answered 2021-Jun-15 at 05:17React hooks are only valid in React functional components, not in any callbacks, loops, conditional blocks. If you need the location data in the callback it needs to be passed in.
From what I can tell it seems you need to move the columns.js
code into the main component so the location
values can be closed over in scope.
QUESTION
I'm attempting to pass my ID variable to my edit function so I can POST my changes to my database. However, I'm receiving this error...
...ANSWER
Answered 2021-Jun-14 at 15:47In your template you're calling your method editData(item)
and you're passing variable item
as your parameter. But in your template there is no such thing defined - I assume (without looking at the rest of your code) that you wanted to write editData(forecast)
instead. This will pass the forecast
variable defined in your *ngFor
directive.

Answered 2021-Jun-12 at 20:01Like you noticed already, you can only check interactions on a mocked object type, i.e. mock, stub or spy. The latter, a spy, is what you need in this case, i.e. something like:
