Question

我需要从主要的电子过程向所有渲染器进程广播消息。 ipcMain没有发送选项，只有通过event.sender.send()回复发件人的选项。

Answer 1

您正在寻找webContents API。来自帖子中的同一页文档：

也可以将消息从主进程发送到渲染器进程，有关详细信息，请参阅webContents.send。

的文档

Answer 2

您可以创建一个窗口数组，然后迭代它们并发送如下消息：

Caused by op u'Variable_2/read', defined at:
File "7.py", line 78, in <module>
b_conv2 = tf.Variable(tf.constant(0.1, shape=[63]))
