QUESTION
I am having a problem with ObservableCollection
. I have two ObservableCollection
. One is old the other new. I want to check if there are items in the old one that aren't there in the new one and remove them (from the old one).
ANSWER
Answered 2021-Apr-22 at 01:32Stepping through the code I noticed that when
result
is changedtmp_Files
also changes.
That's because they reference the same collection. If you don't want tmp_Files
to change, then you need to make a copy of it:
QUESTION
Write a function get_knights_greeting(name, answer='Ni') which returns 'I am of the Knights who say '. Then write another function get_new_knights_greeting with no input parameters that calls the previous function to return 'I am John of the Knights who say Ekke Ekke Ekke Ekke Ptang Zoo Boing!'
I could not find any other answer than below. My question is how can I write John between the given string in get_knights_greeting() function when I am in get_new_knights_greeting() function?
My expected outcome is getting 'I am John of the Knights who say Ekke Ekke Ekke Ekke Ptang Zoo Boing!'
How can I get this outcome using the first function nested in the second function?
...ANSWER
Answered 2020-Apr-09 at 11:30I wonder whether you have transcribed the original question accurately. Surely function get_knights_greeting
is supposed to output its passed parameters. It can do so in several ways:
return 'I am %s of the Knights who say %s' % (name, answer)'
return 'I am {} of the Knights who say {}'.format(name, answer)
return 'I am {name} of the Knights who say {answer}'.format(answer=answer, name=name)
return f'I am {name} of the Knights who say {answer}'

QUESTION
I am creating two buttons, using Corona SDK, one for playing music and the other for stopping. The program works fine up until i create the stop button and nothing works. There is no audio. Can someone help me resolve this please?
...ANSWER
Answered 2020-Jan-27 at 08:13Your buttonHit function is wrong.
You pass in the argument action, however, since you are using widget library, the only thing that gets passed into the function is event. Also, you've given the buttons an id, not an action. This id then belongs to the event target, i.e. the button that is being pressed.
What you want is something along the lines of:

QUESTION
What is the difference between Dispatchers.Main and Dispatchers.Default in Kotlin coroutines?
I used viewModelScope.launch {}
and launch block as expected is executed on UI thread. Then I discovered that it defaults to viewModelScope.launch(Dispatchers.Default) {}
.
This was a bit confusing to me as I thought that I should use Dispatchers.Main
to perform operations on the UI thread.
So far it looks like that on Android Dispatchers.Default
is defaulting to Dispatchers.Main
. Is that right?
Is there any drawbacks if I use one or another or they are interchangeable? If they are interchangeable on Android, is it boing to affect something if in future I will add support of kotlin multiplatform?
...ANSWER
Answered 2020-Jan-08 at 13:55Then I discovered that it defaults to viewModelScope.launch(Dispatchers.Default) {}.
No, viewModelScope.launch()
defaults to Dispatchers.Main
. Google overrides the ordinary default launch()
dispatcher, which is Dispatchers.Default
. I recommend always specifying the dispatcher, rather than having to make people guess which one gets used in which circumstances.
Is that right?
No, sorry.

QUESTION
Kennel has a Dog.
KennelWithPlayground (of type Kennel) has a DogWithABall (of type Dog) and cannot have just a normal Dog.
I want to be able to treat any type of Kennel like it has a normal Dog.
So, I would like to redefine a property of a super class, in a subclass. The new property will be a subclass of the property's superclass. Is this possible in Dart? (something like the 'new' modifier in c# maybe). Or is there another way to achieve this?
The following code does not work because in the KennelWithPlayground class, DogWithABall is not a valid override of Dog.
...ANSWER
Answered 2019-Aug-09 at 11:02It is possible, but if and only if the property has no setter.

This is pretty simple but I can't seem to figure this one out. What am I doing wrong here?

Answered 2019-Feb-23 at 01:58The issue is related to \n
. This token .*
does not match new lines, and it will break whenever there is a new line. This code \n
is interpreted in the Python REPL as a new line, but as a regular text in the Regex 101 website. Try to think of your string this way:
