Windows Dummy Keystroke
This package exports sendDummyKeystroke()
, which will send a generic key down/up event on Windows.
But why?
This is a workaround for an issue with Windows Notifications. Normally you can call the native AllowSetForegroundWindow
method to permit another application to take foreground focus. But when an app is started from a Windows notification activation, this call fails with ERROR_ACCESS_DENIED
. One of a list of conditions has to be met for the call to succeed.
Sending a key press event satisfies this check and lets AllowSetForegroundWindow
succeed.
This is useful for letting a second instance of a program activate the original instance. In Electron, you would call this before calling requestSingleInstanceLock()
, as this can call AllowSetForegroundWindow
for the initial instance.
This workaround was used by Chromium to solve a foreground focus issue, and is adapted here for use with Node.
