I'm wanting to hide the toolbar as I scroll down a page and return it as I scroll up. I have seen this done in UIKit but wanting to know if someone has done this in SwiftUI?

In the below screenshots (taken from the Apple Developer app), we can see that the Account button sticks to the bottom of the sidebar.
When the window is tall enough (left), the list doesn’t scroll, Account button’s background color has no difference. When the window is not tall enough (right), causing the list to scroll, Account button changes its background color to reveal the relationship.
The list's scroll position can not be probed. How can I declare the Account button in SwiftUI?
That app is a UIKit catalyst app and the sidebar uses scrollViewDidScroll which uses the contentSize to set a bottomButtonState which is passed into a child UIHostingController (so the account button can be SwiftUI) which I would assume switches between a clear or solid background.
We cant get the scroll info in SwiftUI however a possible workaround would be to add dummy 1 pixel high cell to the bottom of the list and using its onAppear to set a binding that is used in a bottom view to enable/disable a background colour and should achieve the same effect.
I have started learning swiftUI so I have question about Navigation View. My app starts with splash screen which is embedded in Navigation View and after that I have navigation link to the second screen which is Tab View. Do I need navigation views in child views of Tab View if I have some button etc and I also need to go to other screens from them or I use primary navigation view which tab view is embedded in?
When using both TabView and NavigationView, TabView should always be the parent view and should contain NavigationView inside it.
Hope this clarifies what you’re looking for?
I've designed a toolbox control. It's inside a CDockablePane object. Since the tools inside it may need to be scrolled, I've created a CScrollView as a child of the pane and have inserted the tools inside it as children. Based on the pane size, scrollbars of the CScrollView object appear properly, but clicking on them doesn't scroll the view. It seems that they're disabled. When I use SS_NOTIFY style when creating the CScrollView, the CScrollView object receives mouse clicks, but when i don't use the style, it doesn't. But it seems that the scroll bars inside the view control don't receive clicks. When mouse hover over them, no visual effect in scroll bars appears. It seems that the scroll bars are disabled, while I've not created nor manipulate them.
What's wrong?
mouse wheel works. click on scrollbars is received by the scroll view, not by the scrollbars. inside handler, i wrote this code:
CScrollBar *pScroll = GetScrollBarCtrl(SB_VERT);
if (pScroll->GetSafeHwnd())
{
...
if is not true. this means that the scroll view has not a scroll bar, but if so, how is it shown?!
any idea?
...
since i didn't get answer, i'm going to clarify my question with a sample code:

in this sample, how can i scroll my view as i do with other views like class view and file view?

Did you initialize by calling SetScrollSizes? The scroll bars are enabled only when the sizeTotal is larger than the view window size.

I would like to display the ActionBar alone without any navigation buttons(Home, back,etc) which are present at the bottom of the screen.
If I use '#android:style/Theme.NoTitleBar.Fullscreen', then even the ActionBar is not present.
Is there a way to display ONLY the ACTIONBAR without the navigation bar at the bottom?
For hiding the Navigation Bar, which is there only since API 14, see this
