Prevent gaining focus on os x

[Ibrahim14]

Not every time, but most times when I open a file for edit, after saving it, when the confirmation dialog pops up, FileZilla is gaining focus and brings the window to front. It's annoying because I often hit the save shortcut very often, even before I finish doing the changes.

The behaviour I'm expecting is just to see the bouncing icon in dock, without making FileZilla the foremost application.

That's interesting, there is no code in FileZilla to bring the window to foreground and to give it focus. It may be something OS X is doing or perhaps something deep in the wxWidgets internals.

Which version of OS X are you using?

I'm on latest macOS Sierra 10.12.1. But it was doing the same thing even on earlier versions.

Maybe force the popup window to start with a lower priority?
I researched wxWidgets a week ago for something helpful and found that there is a function ​ShowWithoutActivating(), but I failed in having patience to install all the dependencies for compiling FileZilla in order to try that.
