10 // Google Chrome must depend on GTK 2.18, at least until the next LTS drops
11 // (and we might have to extend which version of GTK we want to target due to
12 // RHEL). To make our porting job for GTK3 easier, we define all the methods
13 // that replace deprecated APIs in this file and then include it everywhere.
14 //
15 // This file is organized first by version, and then with each version,
16 // alphabetically by method.
17 //
18 // For Google Chrome builds, we want to support RHEL 6, which uses GTK 2.18,
19 // but the official builder is Ubuntu Lucid with GTK 2.20. Thus for Google
20 // Chrome builds, we define the GTK 2.20.0 compatibility functions even though
21 // the system GTK provides the functions.
