I am using PanResponder class in react native to achieve this functionalities.
for scrolling I am using scrollTo() . But I am failed do this. I like to share my code but it was too bulky and not understandable.
So my question is Is anyone have any code to achieve this. or Is there any libraries available?
Please help me
Use scrollToEnd({animated: true}) to go the bottom of scrollView in react-native.
From doc.s of facebook https://facebook.github.io/react-native/docs/scrollview#scrolltoend
scrollToEnd()
If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.

I'm trying to build a screen where there is a fixed widget at the top of the screen and another widget which is fixed to the bottom of the screen and in between is a scrollable widget.
I want to have the content inside the scrollable widget scroll underneath the two fixed widgets (both with a transparent blur), to indicate that there is more content underneath.
Here is an image of what I am trying to do.
I am currently using a Stack for this, however I am having to manually adjust the padding in the SingleChildScrollView to offset for the top and bottom widgets, but I would like to have this be much more flexible and have the widgets be any size and not have to update the padding.
I've found other examples where the bottom widget is part of the scrollable content but that isn't quite what I am looking for.
Does anyone know of a way to do this, without having to manually provide the padding?
I don't know how to properly explain this.
I have a svg element which is a big rectangle. If i scroll down, then click on my element, the click isn't registered where my mouse is, but where my mouse would be if i didn't scroll down.
So, if i scroll down by 100px and click on my rectangle, the click will be registered 100px above where i actually clicked.
It's behaving as if i hadn't scrolled down.
Edit: I'm using event.clientX and event.clientY to get the mouse position.
I'm new to svg and i don't know the right keywords to describe my problem.
I'm using svg.js, though i don't think it's relevant to the problem.
I assume this is a well known thing. Can someone point me in the right direction? What kind of keyword am i looking for here?
The problem seems simple enough, i just need to know what to search for.
Thank you.
The problem was the utilization of (event.clientX, event.clientY) to get the mouse position.
In the presence of a vertical and/or horizontal scroll, using these properties caused a mismatch between where the mouse appeared within the page and the mouse position provided by (event.clientX, event.clientY).
I was using the mousedown event, with the mousemove event to create a selection rectangle, similar to what you can find in video games. When horizontal or vertical scrolling had been applied, my selection rectangle didn't appear where my mouse was.
This was solved by using event.pageX and event.pageY (instead of clientX and clientY).
Thank you to #ccprog for pointing me in the right direction.
How to use both vertical and horizontal ScrollView in Xamarin iOS ?
I am using CollectionView but with it I only get one scrollview working at a time.
It's because it's nature of collection view, you can make it scroll in one direction at a time i.e. either horizontal or vertical. What you exactly want to achieve that you have not mentioned. if you are going to use collection view inside the scroll view, you have to manage it properly.
The best solution would be use a UICollectionView for the horizontal
scroll and the UITableView for the vertical scroll.
But if you want to make it work only using UICollectionView you have to use Subclassing UICollectionViewLayout.
here is link you can refer to make it work, hope this might help you:

This is a new one for me. In Design view I am unable to see the first 150 pixels of the design view window-- including the buttons/options to the left of the AppTheme button. I've tried the Pan and Zoom tool, which seems to do nothing. It shows the full view and blueprint view filling the Pan and Zoom tool interface. Any idea how to fix this:
"Window" -> "Restore Default Layout" worked for me.
I had the same problem.
Just drag the mouse where your projects are to the far left of the screen and slowly move with your mouse over to the right until you will see somewhere in the middle resize pointer- thats your design view border. Click it and move to the right and it should appear!
If you want i can try to make a gif how to do it if the above does not help.
I made a site parallax scrolling, using slider and stellarjs.
This works well for scrolling up and down, but it also scrolls horizontally and I do not want.
So i want to disable horizontally scrolling and keep my width at 100% of user screen or at a specific width.
here's the website : ecolopeintre.com/index_para.php
Stellar offers options, please review docs http://markdalgleish.com/projects/stellar.js/docs/
In order to turn off horizontal scrolling please review the code below hopefully it can help.
$.stellar({
horizontalScrolling: false,
});
