Could you make a Windows release? #1

Also, custom colors based on user-determined stdin would be nice .

Thanks

Could you make a Windows release?

How do I cross-compile Qt applications from Linux to Windows?

Is there some e.g. Docker image that just does that?

custom colors based on user-determined stdin would be nice .

Currently it just contains four crude png images. Custom colours would require actually implementing drawing things in the code.

If I knew, I would have built it myself! 😳 However, if I understand correctly, QT is cross-platform and very easy to port.

It would be nice, but it is up to you.

Is it in general a good idea to build Windows GUI apps and release them without having a Windows nearby to test?

(I do that for Rust-based CLI apps and it typically works. But for GUI things it may be different).

gd4c commented 3 years ago

Generally, no. It is always a good idea to test first.

But, as long as your app doesn't interface with low-level features and hardware, I think you should be fine simply testing in a VM.

Found a Docker image to build Qt apps for Windows, tried it: https://github.com/vi/trafficlighticon/releases/download/v0.1.0/trafficlighticon.exe

Does it work for you?

Note that you need to bring your own Qt and Mingw dlls.

gd4c commented 3 years ago

It gives this error: The procedure entry point _Z21qRegisterResourceDataiPKhS0_S0_ could not be located in the dynamic link library <path>\trafficlighticon.exe.

All DLLs are 64-bit and recent ( > 2020-09).

vi commented 3 years ago

Are Qt dlls you used compatible with each other?

Maybe try Qt5 dlls from around 2018?

gd4c commented 3 years ago

Same thing.

I noticed it complains about something in the executable itself rather than the DLLs

vi commented 3 years ago

Another attempt: https://github.com/vi/trafficlighticon/releases/download/v0.1.0/trafficlighticon_static.exe

It starts in Wine and shows the icon. But changing the state based on stdin commands does not work for some reason (icon just disappears). I don't know whether it is because of Wine or because of the bug in the program itself.

gd4c commented 3 years ago

I can confirm the same behavior: Icon appearing (without a color) then closes immediately. Windows has a long-standing bug where if an app crashes, its tray icon won't disappear until you hover over it with the cursor. Don't depend on it to monitor app status.
