[Qemu-devel] [PATCH v3] ui/cocoa.m: Make a better about dialog |
Date: |
Fri, 29 Jul 2016 11:16:49 -0400 |
The about dialog in QEMU on Mac OS X is very plain and unhelpful. This patch
makes the about dialog look a lot better and have some descriptive information
on what version of QEMU the user is running.
Signed-off-by: John Arbuckle <address@hidden>
---
version 3 changes:
Removed buffer related code
version 2 changes:
Added QEMU version to the version label
