pop-up window without a parent use config position

[yim7]

My app has only one pop-up window, but it always shows in top left corner of the screen.

The reason is that the parent window is not considered empty and the calculation of the relative position of the child window fails.

WindowDesc::new(app_ui())
    .window_size(size)
    .set_level(WindowLevel::Tooltip(WindowHandle::default()))

Thanks for the PR! I'm not on windows to test right now, but is this correct in the presence of scaling? It seems like the code in question adds an offset of the parent origin and does some DPI scaling, and I think without the parent you still want the scaling...

You're right, it would be better if the window without parents could be scaled correctly.
A popup window without the parent will be the same as the top-level window. And the position of the window without parents will not be scaled in current druid.
I hope to improve this, but I am not familiar with windows gui.

I'm not convinced that this is a valid premise. The primary window should definitely not be a tooltip. Use WindowLevel::AppWindow for your primary window. The Tooltip, DropDown, and Modal levels are meant for child windows.

Also, as it happens the code in question has been refactored in #2296 so we can't merge anyway.
