Question about using Slint plugin for VSCode in a devcontainer

[cirib88]

Hi there,

I’m currently trying to use the Slint plugin for VSCode within a devcontainer setup. The plugin works fine locally, including the preview, but I’m having trouble getting the preview to work when running in the devcontainer.

When I click on "Preview", I don’t see any error messages, but the preview simply doesn’t show up. Is it possible to use the Slint plugin in a devcontainer? If so, what steps should I follow to get the preview working in this environment? Are there any special configurations or dependencies I need to consider when setting this up?

If the preview isn't working, where would I find more information to troubleshoot why this is happening?

I’d appreciate any tips or guidance from anyone who has experience using the Slint plugin in a devcontainer.

Thanks in advance!

The preview will need at the least to find a way to connect to your windowing system. What windowing system are you using and how is the container set up so that processes inside can connect to the windowing system?

(If we can solve this, then this might be worth adding to our documentation :)

In the vscode settings, you can try selecting the option

Slint › Preview: Provided By Editor

This will enable the wasm preview that should work in a container.

I managed to get the Slint plugin working in my devcontainer setup.

In my case, I was using a Debian-based devcontainer, and I realized that several modules were missing for the Slint server to start properly. After installing the following dependencies, everything worked seamlessly, including the preview:

sudo apt install -y build-essential libx11-xcb1 libx11-dev libxcb1-dev libxkbcommon0 libinput10 libinput-dev libgbm1 libgbm-dev

Once these were installed, the Slint preview started without any issues.

If anyone else is facing similar problems, I recommend checking if these packages are available and installing them in your devcontainer. Hope this helps other!

Thanks for taking the time to document this.
