键盘

例子

WSAD

export function App() {    useEffect(() => {        const context = getAppContext();        const window = context.getWindow();
        // hk: hot key        const hkW = window.HotkeyRegister(KbKey.W, 0);        const hkS = window.HotkeyRegister(KbKey.S, 0);        const hkA = window.HotkeyRegister(KbKey.A, 0);        const hkD = window.HotkeyRegister(KbKey.D, 0);
        window.OnWindowHotkey((sender, nId, key, n) => {            switch (nId) {                case hkW:                    console.log("press w");                    break;                case hkS:                    console.log("press s");                    break;                case hkA:                    console.log("press a");                    break;                case hkD:                    console.log("press d");                    break;            }        });    }, []);
    return <Window></Window>;}

这个例子演示了对键盘事件的响应：按 wsad，然后输出对应按键到控制台：

press wpress spress apress d

API

注册快捷键（hotkey），然后获取一个数字来指代这个快捷键：

export type IWindow<T> = {    HotkeyRegister(key: KbKey, n: InputModifier): number;}
export enum KbKey {    None,
    // Function    Escape,    F1,    F2,    F3,    ...
    A,    B,    C,    D,    E,    F,    G,    H,    I,    J,    K,    L,    M,    ...}
export enum InputModifier {    // Keyboard    LControl /**/ = 0x00000001,    LShift /**/ = 0x00000002,    LMenu /**/ = 0x00000004,    LSys /**/ = 0x00000008,    RControl /**/ = 0x00000010,    ...
    // Pointer    Button1 /**/ = 0x00000100,    Button2 /**/ = 0x00000200,    ...}

这里nId的值都是之前调用HotkeyRegister返回的数字。

export type IWindow<T> = {    OnWindowHotkey(        fn: (sender: T, nId: number, key: KbKey, n: InputModifier) => void,    ): T;};
