How to use InputInjector

[jcdickinson]

I'm trying to use InputInjector and this is as much as I have managed:

use winrt::import;

import!(
    dependencies
        os
    types
        windows::ui::input::preview::injection::InputInjector
        windows::system::VirtualKey
);

use std::time::Duration;
use windows::ui::input::preview::injection::{InjectedInputKeyboardInfo, InputInjector};
use winrt::Array;

fn main() -> winrt::Result<()> {
    let injector = InputInjector::try_create()?;

    loop {
        let info = InjectedInputKeyboardInfo::new()?;
        info.set_virtual_key(9)?;
        let mut arr = Array::with_len(1);
        arr[0] = info;
        injector.inject_keyboard_input(winrt::Param::Owned(arr))?;
        std::thread::sleep(Duration::from_secs(5));
    }
}

It fails to compile with this error (on the inject_keyboard_input line):

the trait `winrt::AbiTransferable` is not implemented for `winrt::Array<windows::ui::input::preview::injection::InjectedInputKeyboardInfo>`

I have also tried Param::Borrowed. Any suggestions?

Related: I can't figure out how to extract the constant value from VirtualKey - if that is at all possible.

The inject_keyboard_input method is expecting a collection interface (IIterable<T>) rather than an array. That explains the parameter mismatch. Unfortunately, Rust/WinRT doesn't yet support implementing polymorphic collections. I'm working on that now. #81
