We have a tooltip component in an Angular ag-grid component. The problem with the default implementation is that our tooltip is rather large and we use scroll view to show all information. However the user never gets a chance to scroll as as soon as he moves the cursor to the right side of the tooltip the cursor leaves the boundary of the original cell and the tooltip goes away. I would imagine that this situation is rather common and there should be a ready solution I just cannot find one.

I have a bunch of horizontal scrolling components stacked on top of each other. When I click one, the browser knows that is the "selected" scroller, and left/right arrow keys will start scrolling that component.
I've tried every element state in dev tools, and haven't been able to find one that correlates with this action. Does anyone know what this state is that I can use?
End goal is to change background color of the "active" scroller (it's not active, I tried!)
I'm trying to figure out how to prevent a popup image from poping up and down repeatedly (forever) when the user moves the mouse to a location on the page.
See https://codesandbox.io/s/jitterbug-on-popup-25kp4 to illustrate the problem. Hover over the text Mouse over this and the Jitter Image will appear to see the jitter problem.
EDIT: Since this was originally posted, I incorporated the solution into the code showing the problem, and now it also shows a solution.
Details
What follows is a text description of the problem, but the code does illustrates the problem as well (and with a lot less text).
On a web page, that has a vertical scroll bar,
The user moves the mouse over a div which has a MouseEnter javascript handler.
the on MouseEnter event fires which causes an image to pop up.
The popup causes the scroll bar to scroll the content. So now, the mouse is no longer hovering over the hover item so the MouseLeave event fires which causes the image to pop down.
With the image no longer being displayed, the scroll bar moves the content back to where it was prior to the popup and viola, the mouse is overtop of the div and the MouseEnter event fires again to pop up the image.
Steps 2-4 repeat forever at the speed at which the browser can keep up.
Or when the user moves the mouse to stop the popup/popdown from happening.
I've seen this happen on some other websites and now that it's happening to me, I want to fix it but I'm not sure how to.
I've searched for a solution but haven't found one yet. Here are some links I found:
https://css-tricks.com/content-jumping-avoid/ - This was good but suggests using min-height which doesn't work in my situation.
I've also tried using overflow: hidden which does prevent the jitter effect described above but leaves the user with no way to see the rest of the popup image. This, however, is a better solution than the jitter effect described above.
I'm using AngularJS and JQuery if that affects the answer.
position:absolute on the image, will solve this as it won't change the current flow when you display the image and the scroll bar will remain in it current position.
My Ionic1 app displays a list of items that can be collapsed/expanded, so the vertical length of the content can increase significantly when an element is expanded (the way I do it is through ng-show directives).
My issue is that when this happens, I cannot scroll down to see the new content. Actually, if I drag my finger from bottom to top, I can see the new content appear in the bottom, but as soon as I release my finger, some elasticity brings back the top of the content.
However, strangely enough, after a few seconds, the scrolling mechanics is updated correctly and I can scroll normally.
It looks like the Ionic framework takes some time to figure out that the content length has changed and needs some update in the scrolling mechanics... I would like to tell him immediately once it is needed. I tried to call $apply from the onClick call back of the Expand buttons, but I get an error saying I am already in a digest cycle.
Any clue to fix this please? Many thanks!
You can avoid $apply approach because every $scope.$apply is rebind in the page. So you can follow the ionic scroll concept.
ionic scroll
Thanks! this helped me fix the problem, by adding a call to $ionicScrollDelegate.resize() whenever some item is collapsed/expanded.
You can check the issue with this fiddle: quickly expand groups 7/8/9 and try to scroll down:

In my GWT application I use a DialogBox like this:
DialogBox dialog = new DialogBox(autoHide, true);
dialog.setText("Hello GWT DialogBox");
dialog.setGlassEnabled(true);
dialog.center();
dialog.show();
My whole page is very long and it scrolls vertically.
This works fine, the dialog pops up and the rest of the page is darkened. When scrolling (with mouse wheel) outside the dialog box nothing happens, which is fine. But when scrolling inside of the dialog box, the whole page scrolls away including the dialog box itself. This feels very wrong.
It is even possible to use scrolling inside the dialog box to scroll the dialog box out of the visible area and then there is no way to scroll it back, because scrolling outside of the dialog box does not do anything.
How to prevent the page from scrolling when using the mouse wheel inside the dialog box?
dialog.setModal(true);
might work. This discards all the events that do not affect the DialogBox, aka scroll that is affecting the underlying page.
WAIT NEVER MIND, DOESN'T WORK
The Page will still scroll if the mouse is within the DialogBox.
Found this though:

Might be useful.
When you navigate to a page with LongListSelector where items have already been loaded (items are already present in itemsSource), the focus, by default is on top most item. You can scroll down to view other items.
In my application, I have a requirement to focus on bottom most item and user can scroll up to view other items.
One solution is to call ScrollTo function on bottom most item. Here, user can see the list being loaded and then change of focus from top to bottom most element. So, the user experience becomes very bad.
Is there any seamless way to do it?
I think ScrollTo is most efficient for a LongListSelector. But if you need to have the experience more seamless you might want to wait/halt your app with a loading screen while the LLS is populated and the focus is changed to the bottom. Async commands or a simple loading status bar could do the trick.
