Is it possible to utilize the identical key in both the render and main processes in Electron?

While exploring electron, I have come across an issue regarding listening for the ESC key in both the main and render processes.

In the Main process,

menu.append(new MenuItem({
    label: "Hide on Escape",
    visible: false,
    accelerator: "Escape",
    click: (item, window, event) => {
      if (window.isVisible()) {
        window.hide();
      }
    }
}))

In the Render Process,

// Key press Handler
const onKeyDownHandler = (event: React.KeyboardEvent) => {
    if (isContentEditable && event.key === "Enter") {
      applyContentEditable();
    } else if (event.key === "Enter") {
      onSelected && onSelected(pair);
    } else if (event.key === "Delete") {
      onDelete && onDelete(pair);
    } else if (event.key === "F2") {
      setIsContentEditable(true);
    } else if (event.key === "Escape") {
      resetContentEditable(); // Stop Renaming and get back to default
    }
}

The issue arises when calling the hide function too soon before reaching the render process. How can I prevent it from hiding when triggered by the Render Process?

Answer №1

One way to halt further propagation or calls on an event is by using the event.stopPropagation() method. You can learn more about it in the official documentation here.

Similarly, there is also a event.preventDefault() method that can be employed to prevent default handling of events. Check out the details here.

If you're struggling to grasp your setup and desired outcome, another approach could be to cease listening for the escape key in the main process altogether. Instead, exclusively listen in the render process and manually transmit the event to the main process when necessary. Consider utilizing the electron ipcMain module for this purpose; additional information can be found here.
