Trackpad | Turns a Keyboard into a Trackpad | Keyboard library

Recently I started studying KivyMD. Whenever I run a simple program the window opens in fullscreen mode(in which the bottom taskbar is not even visible, ie the entire laptop screen is covered by the KivyMD screen) I thought this fullscreen issue was indeed part of KivyMD. I omitted that and started watching KivyMD tutorials on youtube. To my dismay all the tutorials I watched had the KivyMD screen opened in a non-fullscreen mode. This is the first problem I faced. The second issue is the invisible cursor. After I run the program the window opens in fullscreen mode and the cursor remains invisible. Whatever way I wipe on the trackpad, the cursor remains invisible. The moment I exit the program the cursor becomes visible. can someone rectify this issue...

If I use CTRL + scroll wheel or pinch to zoom with my trackpad in Chrome (Windows), I see this weird behavior:

Where the Flutter web app is resizing but also leaving behind artifacts.

If I want to override the scroll to zoom in / trackpad zoom behavior in order to use it in my Flutter web app to zoom in on a canvas for example, this prevents me from doing so. Flutter does not prevent this default behavior, even when I react to zoom gestures.

So how do I prevent this from happening?

I've been trying to figure out the issue for days, but I still can't reproduce it outside of my web app.

I have a scrollable list that looks something like this: https://codesandbox.io/s/jolly-galileo-gk5x1?file=/src/App.js

When scrolling up, new items are loaded on top. I need flex-direction: column-reverse to scroll to the bottom as soon as the page is loaded.

The issue is that when a new item is loaded, it often scrolls up by a few hundred pixels. It happens when I scroll with a mouse or a trackpad on Chrome. It doesn't occur in Firefox, Edge, or Chrome when simulating touch using mobile mode. I couldn't reproduce it in the CodeSandbox link above and my web app isn't live yet.

Adding overflow-anchor: none didn't fix it. What are some other possible issues? I rewrote the c ode several times, so I think it's likely a browser quirk. Also, I don't think this issue occurred before I updated to Chrome 87.

Edit: Disabling smooth scroll seems to fix it. Still trying to figure out how to fix smooth scroll.

When trying to set the max-zoom of a layer to "14", the leaflet-controlls block at 14. But when i try to use the gestures on the trackpad or touchscreen the maxZoom-property seems not to be used.

How can I set the maxZoom for all types of Gestures or Controlls?

This is the configuration I use in my code for my layer:

I'm trying to rotate a wheel based on user interaction. If the user is accelerating his scroll, the wheel should spin faster. Likewise, if the user is decelerating his scroll, the wheel should stop. I'm applying these conditions with styled-components and React state, using the Skrollr library.

Here is what I have:

I'm currently writing a website for a movie making company, which shows their different movies in full-screen. I put each video in a list, and wrote a function that takes the user to the next video everytime a mousewheel event is triggered. The problem is that when the user is mousewheeling with a trackpad, it triggers multiple events at once, so I figured, I just had to set an interval between each triggering, depending on a variable "animating" that would be either true or false.

So here's my code :

I have in my app a layout showing a list of rectangular cards - each one should be tappable (once) to reveal a set of action buttons and more information, etc.

I have implemented this using .onTapGesture() and I have also put .contentShape(Rectangle() to enforce the tappable area. However, while my implementation works fine for touchscreen interface, when I'm using it with the iPadOS mouse support, and on Catalyst for that matter, I see some very unexpected behaviour.

I've made a minimal reproducible example below that you can copy to recreate the problem.

Where the problems are when using mouse/trackpad input:

• Not every click of the mouse is recorded as a tap gesture. This is happening mostly arbitrary except from in a few cases:
• It seems to click either only in very specific areas, or when clicking multiple times in the same spot.
• It seems that in a lot of cases only every other click is recorded. So I double click to get only one tap gesture.
• It isn't evident in this example code, but in my main app the tappable areas are seemingly arbitrary - you can usually click near text or in alignment with it to record a tap gesture, but not always.

If you are running the example code you should be able to see the problem by repeatedly moving the mouse and attempting one click. It doesn't work unless you click multiple times in the same spot.

What does work as expected:

• All input using touch instead of mouse; regardless of where you tap it records a tap gesture.
• Mouse input when running as a native Mac target. The issues mentioned above are only for mouse/trackpad when running the example under iPadOS and Mac Catalyst.

Code I used to recreate this problem (has a counter to count every time a tap gesture is recorded):

So I'm using a regular USB 3rd party keyboard with a chrome OS device in a desktop setup. I want to be able to access all the same features of chrome OS, but some are seemingly not available.

Specifically, overview mode. Accessing it has been described as Overview mode can be achieved by either a 3-finger swipe up or down on your trackpad or by hitting the overview button on the top row of your Chromebook keyboard... But since I'm not using it in tablet or laptop mode, with a 3rd party keyboard -there is seemingly no way to access this feature. No hardware key and no UI icon. Can anyone help?

I have an NSTableView and its parent is the view for an NSMenuItem. The NSTableView is a view-based table. I'm populating the table using bindings with the data coming from an NSArrayController.

The performance of scrolling in the NSTableView is abysmal. It seems like the scrolling function is not "continuous" and only scrolls once I have lifted my fingers off the trackpad. The behavior is sort of like when you have a text field and it only sends its action upon hitting the return key as opposed to sending the action continuously.

If I open and close the menu enough times, the table will scroll smoothly for a part of the NSTableView, but quickly reverts to jerky scrolling. I can also click and drag to effectively scroll through the rows relatively smoothly, but again, the two-fingered scroll gesture is super-clunky.

Below is the code for how the table is being populated. In IB, the text field is bound to the name property, and the NSImageView is bound to the icon property of a custom class called AmphRunningApp.
