From 965bcca6d4e22788721a9af906adfbd97af9af29 Mon Sep 17 00:00:00 2001 From: Andy Shaw <andy.shaw@qt.io> Date: Thu, 23 Mar 2017 17:49:16 +0100 Subject: [PATCH] Cocoa: Explicitly hide popup windows when the application is hidden MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the application is hidden then Qt will hide the popup windows associated with it when it has lost the activation for the application. However, when it gets to this point it believes the popup windows to be hidden already due to the fact that the application itself is hidden. As a result, when the application is restored it causes a problem with the still visible popup window as it is taking the input events without responding to them. Therefore we need to explicitly hide the windows right before the application is hidden to ensure that they are actually hidden correctly.
