scrolls | Made for writers | Icon library

Below is a screenshot of my current situation. Is it possible to make the text within the blob.svg white, and the text outside the blob.svg the color of the blob (#e60050)?

There is also a parallax effect on this particular element. The blob scrolls slower than the text. Therefore the text does not always overlap the blob in the same way/position. Based on the scrolling position, the text may even be completely within or without the blob.

I have been messing around with various implementations of mix-blend-mode now, but i can't seem to figure it out.

Current situation

Using Vue, I have the following setup in a component:

I have an svg which forms the basis of my horizontal scroller.

Within this svg, I have added the class .animate to the elements which I want to fade in up as the item comes into view. The .animate class for reference has been added to all the text items in the svg.

Currently, only the .animate elements that are in view initially fade in up. When I scroll down to continue the scroller, the other elements are static. They're not fading in or translating up or down in any way?

TL;DR, here is what I'm trying to achieve:

• When the scroller pins in place, and the user continued to scroll down, start fading away .horizontalScroller__intro.
• Once .horizontalScroller__intro has faded away, start the horizontal scroll for .horizontalScroller__items
• Any elements with the class of .animate in my scroller will fade in up to its original position.

Note: I understand SO rules and preferences to post code here. But, my demo's contain a length SVG, which I cannot post here as it exceeds SO's character limit.

Here is a demo of my latest approach

From the scrollTrigger docs, containerAnimation is what helps achieve animations on horizontal scrollers, and is what I've tried to achieve.

However, in my demo above, I have the following issues:

1. .horizontalScroller__intro doesn't show initially, when it should, and should fade out on scroll.
2. The horizontal scroller doesn't work anymore
3. The .animate elements that are in view, do not fade in up

If I use timeline (see below snippet), then the intro fade out and scroller works. But, doesn't animate in the child elements, which is where I need containerAnimation

After Android Studio upgraded itself to version Arctic Fox, I now get these strange sub-windows in my code editor that I can't get rid of. If I click in either of the 2 sub-windows (a one-line window at the top or a 5-line window underneath it (see pic below), it scrolls to the code in question and the sub-windows disappear. But as soon as I navigate away from that code, these sub-windows mysteriously reappear. I can't figure out how to get rid of this.

I restarted Studio and it seemed to go away. Then I refactored a piece of code (Extract to Method Ctrl+Alt+M) and then these windows appeared again. Sometimes these windows appear on a 2nd monitor instead of on top of the code area on the monitor with Android Studio. But eventually they end up back on top of my code editor window.

I have searched hi and low for what this is. Studio help, new features, blog, etc. I am sure that I am just using the wrong terminology to find the answer, so hoping someone else knows.

How do i change how much a single mouse scroll wheel step scrolls in a Flutter Desktop App (Windows, macOS, Linux), without affecting touchpad scrolling speed?

The default scroll wheel step size is too small, especially on 4K monitors.

If i multiply the step size through scroll listener, it breaks touchpad scrolling, makes it too fast.

I maybe need to somehow distinguish between touchpad scroll and mousewheel scroll?

I use this code to scroll:

In HTML, there is a that redirects to another component, and after that scrolls to a certain anchor.

EDIT [resolved]

based on the answer from Thingamabobs below, the approach simply turns out to be making sure the elements you spawn are allocated to correct parents.

It is worthwhile to create a frame just to hold every scrollable element since you can't move widgets around between parents when using pack/place. So a common parents between all movable elements will give you the freedom to move them around, again just create a holder frame. See the answer and discussion below for more details.

EDIT2

Bryan's answer below has very good info and an alternate approach using just a canvas. The core concepts still stand the same.

original question begins here

So based on this answer by Bryan, I used this approach to spawn widgets on a scrollable frame (which is basically a Canvas wrapping a frame inside as we know cause Frames don't have scroll attributes).

The widgets in this case are just tk.Buttons which I spawn in a loop using lambda to preserve state. That aspect is completely fine.

Now everything works fine except when I spawn more elements (again just buttons), they seem to be cut off. and I can't seem to scroll down to see the remaining ones. I am only able to scroll upwards only to see empty space.

please see the video below to see what I mean (excuse my horrible color choices, this is for a quick demo)

In the video, there are more elements below template47 but I can not scroll to them. I can scroll upwards but it's just lonely up there. All the names are actually buttons with zero bd and HLthickness.

To begin, my first instinct was to attach a ttk.scrollbar to the canvas+frame, which I did but observed the exact same behavior.

Then I tried to see if i could use .moveTo('1.0') to scroll down to last entry and then since upward scrolling works already, shouldn't have an issue. But this didn't do anything either. Still the elements were cut off, and it obviously messed up upward scrolling too.

I don't think I can use pack/grid geoManagers since as the answer by bryan i linked to above suggests, using place with its in_ arg is the preferred way. If it is possible otherwise, let me know though.

as depicted in the answer linked above, I also have two frames, and I'm using the on_click callback function to switch parents (a lot like in example code in answer). Turned out place was the best bet to achieve this. and it is, all of that aspect is working well. It's just the scroll thingy which doesn't work.

how i bind to mousewheel

As can be seen in official documents there is layout named SubcomposeLayout defined as

Analogue of Layout which allows to subcompose the actual content during the measuring stage for example to use the values calculated during the measurement as params for the composition of the children.

Possible use cases:

You need to know the constraints passed by the parent during the composition and can't solve your use case with just custom Layout or LayoutModifier. See androidx.compose.foundation.layout.BoxWithConstraints.

You want to use the size of one child during the composition of the second child.

You want to compose your items lazily based on the available size. For example you have a list of 100 items and instead of composing all of them you only compose the ones which are currently visible(say 5 of them) and compose next items when the component is scrolled.

I searched Stackoverflow with SubcomposeLayout keyword but couldn't find anything about it, created this sample code, copied most of it from official document, to test and learn how it works
