Stop scrollview from consuming the interface

[rnd-ash]

My application has a main UI page which is broken down into 2 parts:

1. main interface which can change
2. Bottom status bar which is permanently on screen

With the UI with explain enabled, you can see this:

Under log view in this image is a scrollview. Below that is a space followed by the status bar. It is drawn like so:

let mut c: Element<_> = Column::new()
                .push(view_contents) // Draw the custom view on screen
                .push(Space::with_height(Length::Fill)) // Pad the gap
                .push(Rule::horizontal(1)) // Draw a line
                .push(s_bar) // Draw the status bar
                .into();
if themes::is_debug() {
    c = c.explain(iced::Color::BLACK);
}
container(c)
    .height(Length::Fill)
    .width(Length::Fill)
    .into()

however, when I keep adding elements to the scrollview, this eventually happens:

Here, the scrollview has completely consumed the interface.

How would it be possible to stop this behavior?. I don't want to use the max_height function on the scrollview as i still want the entire UI to be adaptive according to the window size rather than creating a hard limit.

+1 for this

This is caused by a limitation / bug of the current layout engine and widget implementation.

In order to fix this, you have to explicitly state height(Length::Fill) for all of the parent containers of the Scrollable.

In any case, we should really tackle this limitation soon. I will work on it right away!

Fixed by #2192.

I think this is still happening with version 0.12. I have a scrollable which can become quite lengthy and two buttons beneath it. If the scrollable takes up more space than the window offers, it pushes the button out of the window.

My proejct
You will have to choose the attached input file, then click "Create Personal Running Order".

Input file:
data_summerbreeze2022.csv

This is the default for me when it opens:

Then, enlarging the window to make everything fit:

If there is barely space for the buttons, they are rendered very small (without text, I think)

The view is created in src/gui/band_selection_view.rs and src/band.rs (and excuse the hardcoded parts, this is still very much a work in progress).
