| Title: Library initialization and versioning |
| |
| The GDK and GTK headers annotate deprecated APIs in a way that produces |
| compiler warnings if these deprecated APIs are used. The warnings |
| can be turned off by defining the macro `GDK_DISABLE_DEPRECATION_WARNINGS` |
| before including the `gdk.h` header. |
| |
| GDK and GTK also provide support for building applications against defined |
| subsets of deprecated or new APIs. You can define the macro |
| `GDK_VERSION_MIN_REQUIRED` to specify up to what version you want to receive |
| warnings about deprecated APIs; and the macro `GDK_VERSION_MAX_ALLOWED` to |
| specify the newest version whose API you want to use. If you attempt to use |
| a function deprecated before the version of GTK specified in |
| `GDK_VERSION_MIN_REQUIRED`, or a function introduced after the version of |
| GTK specified in `GDK_VERSION_MAX_ALLOWED`, the compiler will warn you when |
| building your code. |
