From 70f4bf1a487aa56e9667b92f420926e353ba7862 Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Fri, 14 Feb 2014 17:45:41 +0100 Subject: QPlatformDialogHelper: change ButtonRole flags to ensure 32-bit size 0x80000000 is too big for a signed 32-bit int, so the compiler ends up choosing a 64-bit number. Then it will not be the same size as the parallel enum QDialogButtonBox::ButtonRole, which does not have these extra flags. By making EOL be the same as InvalidRole and changing Reverse to 0x40000000, we don't need to use 0x80000000 at all, so again the compiler can choose a 32-bit representation for both if appropriate. EOL is used as a terminator in the static const int buttonRoleLayouts table and therefore as a terminator in arrays returned from QPlatformDialogHelper::buttonLayout(). It's internal API so it's OK to change in a minor release, but QtQuick.Dialogs is also looking for the EOL now, so we should avoid changing it again if possible. This is mainly for efficiency and for avoiding surprise data type conversions when casting from one enum to the other.
