It looks like AbstractPlane::activate assumes that a plane cannot be both hidden and at the front of the hierarchy, and there is an assertion enforcing this:

In my usage, this assertion has had a lot of failures. For example, if you:

1. Create a UserInterface
2. Add a Plane to it
3. Call Plane::hide()
4. Call Plane::activate()

This causes a crash, even though it seems like perfectly legitimate usage.

I was able to fix it for my purposes by just deleting the if-statement and the two lines inside it. But I suspect that there's a reason that assertion is there, which is why I'm hesitant to submit a PR.

I know this project is on hold, but I thought I would file an issue in case someone picks it up again (or someone with the same problem as me checks the issues for help).

Hi @mosra !

As per gitter, I have a use case (some drop event) where I would like to be able to query the hovered widget(s) (e.g. the toplevel widget of some stack as you suggested).

Cheers, Jonathan

I tried following the instructions from Magnum's building docs and wanted to install the Emscripten wasm toolchain, however these pkgbuild's are not available in the AUR and installing them via makepkg gives me unresolved dependency errors.

Ξ package/archlinux → makepkg --nocheck -fp PKGBUILD-emscripten-webgl2
==> Making package: emscripten-magnum-extras dev.webgl2-1 (Tue 06 Dec 2022 07:15:34 PM IST)
==> Checking runtime dependencies...
==> Missing dependencies:
  -> emscripten-magnum=dev.webgl2
  -> emscripten-magnum-plugins=dev.webgl2
==> Checking buildtime dependencies...
==> ERROR: Could not resolve all dependencies.

How do I go about installing those? What is the procedure?

Actually build failed when I installed magnum-extras[ui]:x86-windows

here is the log

https://doc.magnum.graphics/magnum/ui.html

Since the doc explicitly mentions it's not documented yet, I would like to ask some questions regarding the UI - I have an open-source project in mind and would like to use Magnum to make both a desktop and a web-based application (and to let you know - you have superior licensing compared to Qt).

• Do I need to use the Dear Imgui library?
  • If yes, how customizable it is? Can I change only colors or more (like geometry, size, alignment etc)
  • If not - is there any way to have custom widgets? Doc mentions there is a singal+slot system - as long as there is a sort of 2D canvas (similar to HTML 5 canvas API) I'm fine with it to draw my own widgets and implement my event handlers.

usr/share/cmake* is missing at magnum-extras/package/debian/magnum-extras-dev.install.

Having no luck compiling Ui for Android.
Tested with Android-Studio, gradle command-line and CMake cross-compilation. Same error.
Hoping it's a simple thing like missing Header or something stupid on my part that I've missed.
