Question 1

How do I compile a MUI app for the web with Emscripten?

Accepted Answer

Use the -d emscripten flag with V, patch the output .c file using sed to fix waitpid calls, then compile with emcc and specific flags like -s ALLOW_MEMORY_GROWTH. It's experimental and may require adjustments for different setups.

Question 2

MUI or ImGui for building desktop apps in C?

Accepted Answer

MUI is better for cross-platform consistency and system theme integration in V/C, while ImGui is immediate-mode and C++-focused with a different performance profile. Choose MUI if you need V language support or native look-and-feel.

Question 3

Does MUI work on MacOS for basic applications?

Accepted Answer

Basic widget drawing and click handling should function, but themes and screen reader support won't work, and there may be MacOS-specific bugs, as noted in the README. It's not fully tested or supported.

Question 4

What's the best way to prevent UI freezing in MUI with long tasks?

Accepted Answer

Run processes over 0.2s concurrently using V's go routines, as per the README suggestions. This keeps the UI responsive, especially for dialogs or heavy computations.

Question 5

Can I use MUI with the TCC compiler on Windows?

Accepted Answer

Yes, but with limitations: webview submodule doesn't work, and you need full winapi from a specific download. Follow the FAQ steps to set up TCC, but GCC is recommended for full functionality.

Question 6

How to add tray icons to MUI applications?

Accepted Answer

Use the external VTray library, as MUI doesn't have built-in tray support but is interoperable with it. Check the VTray GitHub for integration details and report any issues.
