QUESTION
Here's a codepen demonstrating a treetable with groups:
https://codepen.io/dharmatech/full/mdWGbox
ScreenshotScreenshot of the above treetable:
The IssueOnly some of the columns are shown; there are many more available. However, note that there is no horizontal scrollbar shown at the bottom to bring the other columns into view.
Is there a way to turn on a horizontal scrollbar?
Approaches I've exploredI've tried each of these:
...ANSWER
Answered 2021-Jun-11 at 09:04Your code is correct. And TreeTable does show all columns, you just miss the horizontal scroll at bottom of the grid.
To fix the situation, you need to
- init UI in container ( currently it is atached to the body ). To do so you need to add
container
property to the UI configuration
QUESTION
I'm trying to get documents in brews collection from firestore database.
I wrote code like below but it's getting empty array.
What is wrong with my code?
Help me somebody who is used to flutter and firebase.
...ANSWER
Answered 2021-Apr-25 at 01:55Your Print is trying to convert an array of objects to a string that isn't valid or Stringable since it also contains circular references.
However, snapshot.docs
are iterable, and using forEach will process each document for your needs.
Just ensure that the snapshot is finalized before processing it by awaiting it or handling it inside your Stream Provider as needed.
You can check the count of the documents with snapshot.docs.length
if you are seeing values return, you will have to debug further.
QUESTION
I have trouble understanding this syntax. I didn't find the answer to my quesion in the Agda tutorial manual. The only thing I found was that (x : A) -> (y : A) -> B
sugars to (x : A)(y : A) -> B
which sugars into (x y : A) -> B
, but this isn't the whole story.
What troubles me is that type declaration:
map : {A B : Set} -> (A -> B) -> List A -> List B
is fine, while
map : {A B : Set} (A -> B) -> List A -> List B
is not.
Version with arrow between arguments
singleton : {A : Set} -> (x : A) → List A
is fine, while the same expression without arrow
singleton : {A : Set}(x : A) → List A
is still fine.
The version with ':' between arguments

...ANSWER
Answered 2021-Mar-05 at 15:52Quoting the OCaml Towards Clarity and Grace style guide:
Code is more often read than written - make the life of the reader easy
and
Less code is better, cryptic code is worse
The first makes me think that the version with multiple when
clauses is the better choice, as it makes it easy to predict or evaluate the result when reading the code depending on condition. The second goes further, against the if-then-else
because, even if shorter, is cryptic when looking from afar.
Also, in the section Functions, we find out that "Pattern matching is the preferred way to define functions"
From a Haskell functional programmer's point of view.

I'm learning Flutter and as an exercise I'm interfacing with Firebase (I'm also new to this - my first encounter). In the exercise when we register a new user we create a document for the newly registered user with default values.

QUESTION
I am using Windows Forms .NET C# for this project I am making a school project for a cafe ordering system. And the coffee aspect is a simple custom controller that allows users to pick out a size of the coffee, how many sugars and creams they want. My issue is that I then have to take that user control inputs and store them in the main form list and inside a ListBox as a display of an order.
Does anyone know how to store user control inputs into a main form List<>?
...ANSWER
Answered 2020-Nov-27 at 18:52The best way is to create a class to store info about order, let's call it class "Order". Each order will be represented by instance of this class (you pass your control's values as parameters to the constructor). You can store orders in the List.
To add it to the ListBox, you must override ToString() method:
public override string ToString(){ return "onfo to show" }
This method will show info about order from your class in the way you like.
P.s. for more specific help provide sample code of what you have tried since now.
