            Div with absolute width is smaller than specified
            Asked 2021-Jun-15 at 20:37

            I am trying to have a number of columns with exact widths, and their heights split evenly between some number of elements. For some reason, despite my indicating an exact 200px width on each column, they are instead getting a computed width of 162px somehow. Chrome dev tools is showing some weird arrow thing indicating that it it was shrunk from it's intended size for some reason. I've even tried removing all of the content from the div's as possible so as to rule out some weird interaction with the size of children.

            Setting display: flex turns the sizing of child elements over to the flex container. If you don't want the individual elements to resize, set flex-grow: 0, flex-shrink: 0, and flex-basis: 200px. You can do all three using the flex shorthand:

            Qt - trying to align two GroupBoxes in a layout
            Asked 2021-Jun-15 at 17:18

            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)?

            ...

            ANSWER

            Answered 2021-Jun-15 at 17:18

            Items will be aligned if both QGroupBoxes 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).

            React Router Link changes URL but doesn't render Component - Rest Countries API
            Asked 2021-Jun-15 at 17:07

I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.

            Issue

            The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.

            Solution

            The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.

            Changing the PowerShell Window Font

            To do this, right-click your PowerShell window and head to "Properties"

            There, you can choose the header "Font" and change your font to Cascadia Code PL".

            This should fix the problem. If you still experience some weird characters, you might need to install a Nerd Font instead.

            Changing the VS Code Terminal Font

            To use the font in the VS Code Terminal, head to Settings.

            Searching for "integrated terminal font family" should bring up the setting you need to edit. Here, add your font 'Cascadia Code PL' on the very front of the setting and save.

            Integrated:Font Family"" />

            You should now be able to open a terminal and use the PL prompt.
