I‘m trying to do drag and drop scenario in a list of elements.Currently I’m using Actions class to do the job, but it’s hang the process when trying to drop the element to the target position.
I’ve tried following solutions so far,
dragAndDrop(source,target)
clickAndHold(source) , release(target) - here release not happened until manually do the mouse movement.
Javascripts dragAndDrops not worked in the application
Robot class - not getting the exact element position in the local machine plus in the servers.
As my guess best way to do this from actions class , Any solution for doing clickAndHold and once release function called do the mouseMovement from automation.It will hang the process inside the release function. And moveToElement will not work as well.

I am using React
I want to animate a series of chronological events occurring in network graph.
Requirements as follows;
Network graph displayed is statically drawn (i.e: nodes and edges never change)
Given a dynamic list of chronological events (which come from an api), animation shows the nodes in the network highlighted one after another for the given times
There is a play/pause slider to play/pause and scroll through the animation
The events are shown in a table and table rows can be clicked on to jump to the time in the animation they occured
Would also be nice to be able to play animation at 2x, 4x ... speeds
My questions
How can this be implemented in react?
Is there any library that can help me with this?
Or any similar project which may be a good starting point?
My thoughts
I am totally open to any open source solution as long as it can be implemented using react.
I am thinking of using d3 (though I have no prior experience). The following examples seem somewhat similar to what I want to do.

I am trying to build a react application that can create a card component and connect them, and they also can pan and zoom the screen also drag those cards. Like the building window in Figma or Adobe XD. Can anyone suggest to me any popular and effective solution or packages for it. I have been doing some research for a few days now and I could not get a proper solution for it.
You can use drag&drop functionality, basically you need to handle callbacks when drag&drop events happen (onDragStart, onDragEnd, onDragEnter ...), you get data from the event parameter. When something is dropped, you update the state accordingly (add/remove item from list), and render them with map function. Some sample: https://codesandbox.io/s/reactdrag-and-drop-iq89y?file=/src/components/TaskList.jsx
I can find a few thousand examples of creating new windows with electron, and how to change out the current main windows to a new file, But I'm really stumped when it comes to being able to smoothly transition between pages.
I could build all the functionality into the index and swap it out, but that seems overly complex and load heavy.
I could use one of the react bootstraps but this seems rather heavy on learning and counter intuitive to Electron (Plus a massive amount of messing around with multiple package loaders and other such things I've seen).
I've seen some things in the docs for child windows and seem someone suggest the use of those, or hidden windows to pre-load content, append onto the existing page, animate then remove the old. But that just sounds like a nightmare when it comes to adding event listeners.
I just need a way to be able to transition nicely between say a splash page and a load page, then the app page
Then say in the app transition in a modal
Personally I use multiple windows and if the user clicks on the close button for one of them I do not perform a window.close() but a hide(). In addition on every close button press I check if at least one window is left to keep the app alive. If not I exit the application. For ipc calls I introduced a naming convention like: "settings_win-operation1", "splash_win-operation1" and so forth.
I have been trying to develop a very basic game using Ionic. Initially, I was using pure JavaScript to listen to clicks and then act on them but the response time was very long. When I asked a question on Stack overflow, it was suggested that I should be using Angular JS to work optimally with Ionic apps. Now, I have started using Ionic but the response time is still very very slow.
I am using ng-mousedown and ng-mouseup to detect mouse down and mouse up events. The buttons are positioned absolutely over a canvas element which occupies all the screen space. A single tap on any of the buttons results in no response. I have to keep the button pressed for some time before the logic kicks in. There is no such lag on my PC. Can anyone please guide me on how can I improve the response time?
Let me know if I need to add any code here but it doesn't seem to be a problem with the code because there is no such issue on PC.
Try this...It should solve your problem..Actually the ionic.js is sometimes responsible for delays Ionic handle delay
Eventually, their may be a system performance related issue.If, other apps are lagging behind.
I have a fairly simple RN app with a layout similar to this:
As shown in my image, I have four Touchable columns equally splitting the screen.
Everything works fine. But here is what I'm trying to do now: wherever a user touches the screen, I need to append an element where the touch interaction occured and on top of everything.
First, I naively added a new TouchableWithoutFeedback on top of my other views, but this simply prevented onPress to be fired on those other views.
Then I began to realize that this was not as simple as I thought and took a look to the Gesture Responder System. I think I got the concept but I didn't achieve anything with it yet...
Is it possible to let onPress events to bubble up through every layers ?
