QUESTION
I'm trying to migrate an existing, small Flutter app to Flutter 2.12. The null safety thing is new and still confusing to me. For the most part I have been successful in resolving the errors from the migration, but I haven't found a solution for this problem. Here we go:

QUESTION
I'm trying to set up different Xmonad key mappings depending on the number of connected monitors. The reason is that I use the same Xmonad config file on multiple systems (desktops, a laptop with different monitor configurations including 3 displays). Displays are listed in a different order on different systems, that's why I need to hardcode display indices when using a 3 monitor setup.
My current best try is something like that (everything that is not relevant has been removed):
...ANSWER
Answered 2021-Jun-14 at 10:51not too familiar with Xmonad but you can easily do the following I guess. create a pure function mkConfig
which takes the number of screens and returns the desired key mapping. Then, in your main
pass it to xmonad
function. I haven't tried to compile any of this but probably you can modify it easily
QUESTION
This is a simple one for JS programmers. Base on this demo, https://codepen.io/gschier/pen/jkivt
I want 'The pen is simple.' to be 'The pen issimple.' To remove the space after 'is'.
I tried different areas with no luck. I only know CSS and HTML but not so much JS.
Of course this doesn't make sense with this demo example, I want to start it with an alphabet to make a sentence, for example

QUESTION
Valid under help centre guidelines:software tools commonly used by programmers. I would like to start PyCharm and for it to automatically open the programs I had open when I closed PyCharm in the previous session (i.e. start where I left off). I usually have several concurrent programs from very different locations, so finding them all manually is a pain. Is there a way this can happen automatically?

QUESTION
I have created an API and I am trying to provide permissions to the views in my API app. I have assigned users to groups with permissions in my admin portal and then I am using DjangoModelPermissions in my views so that the permissions behave according to the admin portal which is not working. When I use IsAdminUser then its working it is preventing other users to read the view. but for DjangoModelPermissions it is not working.
In simple terms I want to block access to views for few users even after assigning permissions and passing this value DjangoModelPermissions in permission glass that user is still able to get access for that view.
Users and Groups in my admin group One super_user assigned to Developers groups with all permissions. One Testuser assigned to Language groups with only access to language view.

Good day fellow programmers,
I have a simple domain expressed as follows:
...ANSWER
Answered 2021-Jun-05 at 01:19You could check for the default value of int

QUESTION
without losing hyperlink or read more goes below text
Any ideas to keep 'read more' next to text and remove 'p' from var content = $(".myClass p").html(); without losing hyperlink ? Thanks a lot..
...ANSWER
Answered 2021-Jun-04 at 02:55Just one small thing to do and this should work fine. You can include The child combinator ( > ) to capture p
tag within .myClass
while omitting to write the tag in your third line, i.e. var content = $(".myClass").html();

QUESTION
I am creating a Smart Contract (BEP20 token) based on the BEP20Token template (https://github.com/binance-chain/bsc-genesis-contract/blob/master/contracts/bep20_template/BEP20Token.template). The public contructor was modified to add some token details. However all of the standard functions are giving compile time issues like Overriding function is missing.
** here is the source code **
...ANSWER
Answered 2021-May-11 at 13:28Constructor public () - Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it "abstract" is sufficient.
The warning message says it all. You can safely remove the public
visibility modifier because it's ignored anyway.
If you marked the BEP20Token
contract abstract, you would need to have a child contract inheriting from it, could not deploy the BEP20Token
itself, but would have to deploy the child contract. Which is not what you want in this case.

ANSWER
Answered 2021-Jun-01 at 18:25All QObjects will delete their own child objects automatically. (See docs here.) QWidgets are QObjects. So as long as you establish a parent/child relationship, you do not need to manually delete your objects. To do that, simply pass a pointer to the parent object to the constructor:
QUESTION
Hello fellow programmers,
For a project I want to generate a stacked bar chart plot. I was succesful at this. However, I want to add a label to every bar to indicate the size of each bar. I read the demo on the fairly new added function to matplotlib called the bar label: Bar Label Demo.
The solution I tried to come up with is as follows:
...ANSWER
Answered 2021-May-31 at 18:43When you iterate to add the labels at the end the objects held in c
are instances of matplotlib.container.BarContainer
. These have an attribute datavalues
which are used for labelling unless you provide other labels to matplotlib.axes.Axes.bar_label
with the parameter labels
.
Therefore, setting empty strings for 0
values allows you to control what is added:

Install programmers
You can use programmers like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
