ChatUI | UI design language and React library | User Interface library

I want to using Dialogflow framework within website . I know dialogflow offers the website integration as widget but.I want to use in it a custom designed floating chatbox in website.Like a chatbox which hovers in the corner of the page.How can i integrate with such chatUI

I am trying to create a simple chat program.
Initially I wrote this code to save an input message from user into a Text file, depending on the given Command, but I don't have any idea about the testing strategy. Should I write test for the runUi() only? Because this method already contains switch statement and inside it are the other methods invoked, or should I write for all other methods as well?

Am trying to match email,phone,email,hashtags and mention tag in a message and insert them inside a hyper link. But am having problem with my regex as it doesn't match emails as mail instead it match as a link.

Below is a working example.

I'm trying to understand well the Flutter Lifecycle and I'm not sure that is normal that events like PUSH a view occurs twice. I'm searching for a event that occurs one time only when the view is showed. For example: ViewA is showed eventImSearchingOn occurs one only time. ViewA open ViewB, ViewA is deactivate. ViewB go back to ViewA and eventImSearchingOn occurs one only time.

The log of the code that I've tried:

New to React/Redux combo and trying to work through an issue.

When a user first visits or logs in / a fetch_user api request is made. The intention is that the page would display differently based on their login status. In redux dev tools I can see the state being updated and fields being populated to 'auth' after the initial state, however, while I am in a subcomponent of the app the value is seen as undefined. Please let me know if you need any more information. Thanks in advance.

The answer was more simple than the code below - the code above uses QPropertyAnimation rather than using for loops with QThread like below - which saves tons of space in the code and is more efficient.

Original question below:

I am writing an application in Qt and I am having an issue with closing the application and the threads.

Basically, the application window closes, however the process remains in the background and never closes.

my main header (just included the class since there are a lot of includes):

if i write this onPress={() => this.submit()} instead onPress={() => this.onSendBtnPressed()} i can get the text value but if i just write onPress={() => this.onSendBtnPressed()} this i can't see the text on the message list
