键盘

例子

WSAD

examples/unit/keyboard-event/event-basic.ts

export function main(window: Window) {    // 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;        }    });
    const container = getControlDemoContainer(window);    window.SetContent(container);}

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;};
