Direct Write support?

Does Neovim-qt support Direct Write on Microsoft Windows?

AFAIK Qt does not enable directwrite by default. I think you would need to rebuild Qt to support it.

We don't support windows xp, so should we not enable this by default? this and this suggest Windows Vista and later will work.

Its not under my control, it is configured in the Qt library at compile time.

(note: In order to get support for the DirectWrite back-end, you need to build Qt with the configuration flag “-directwrite” which will make your applications depend on DirectWrite support from your target platforms.)

I think the default Qt builds dont have it enabled, but I may me wrong.

According to the changelog of 5.6.0: "DirectWrite support is now the default if available". I checked the latest source, and there is a command line option to disable it.

Is there any chance that you'll provide windows builds with direct write support in the future? Thanks

@harg How do you confirm that DirectWrite is not enabled? The rendering output is not very relevant, given that neovim-qt uses it's own way to render text looping over the characters of the line. That will skip shaping features, as I understand it.

Sorry, i thought that Direct Write was enabled based on the rendering. Is it possible to have the same rendering as Gvim on Windows?

We don't really have a path forward here. Closing. But feel free to open issues with good approaches that improve this.
