Electron：不使用框架实现自定义的可拖拽标题栏

preload.js:

contextBridge.exposeInMainWorld('window_control', {
    toClose: () => ipcRenderer.send('close-app'),
    toMinimize: () => ipcRenderer.send('min-app'),
    windowMove: (canMove) => ipcRenderer.send("window-move-open", canMove)
})

最小化

renderer.js

document.querySelector(".my-btn-minimize").addEventListener('click', () => {
    window.window_control.toMinimize()
})

main.js

ipcMain.on('min-app', () => {
     if(win){
        win.minimize()
    }
})

最大化同理

关闭窗口

renderer.js

document.querySelector(".my-btn-close").addEventListener('click', () => {
    window.window_control.toClose()
})

main.js

ipcMain.on('close-app', () => {
    if(win) {
        win.close()
    }
})

拖拽窗口

randerer.js

function titleDown(e) {
    window.window_control.windowMove(true)
}
function titleUp(e){
    window.window_control.windowMove(false)
}

main.js

ipcMain.on("window-move-open", (events, canMoving) => {
    if (canMoving) {
        // 读取原位置
        const winPosition = win.getPosition();
        winStartPosition = { x: winPosition[0], y: winPosition[1] };
        mouseStartPosition = screen.getCursorScreenPoint();
        // 清除
        if (movingInterval) {
            clearInterval(movingInterval);
        }
        // 新开
        movingInterval = setInterval(() => {
            // 实时更新位置
            const cursorPosition = screen.getCursorScreenPoint();
            const x = winStartPosition.x + cursorPosition.x - mouseStartPosition.x;
            const y = winStartPosition.y + cursorPosition.y - mouseStartPosition.y;
            win.setPosition(x, y, true);
        }, 10);
    } else {
        clearInterval(movingInterval);
        movingInterval = null;
    }
});

setInterval函数的第二个参数，也就是定时器间隔，会直接决定拖拽窗口的流畅感，但是如果设置太低……会出问题！

使标题栏内容不可选择

style.css

.my-title {
    -webkit-user-select: none;

}
