setAllowedBackends

fun setAllowedBackends(backends: String)

Sets a list of backends that GDK should try to use.

This can be useful if your application does not work with certain GDK backends.

By default, GDK tries all included backends.

For example:

gdk_set_allowed_backends ("wayland,macos,*");

instructs GDK to try the Wayland backend first, followed by the MacOs backend, and then all others.

If the GDK_BACKEND environment variable is set, it determines what backends are tried in what order, while still respecting the set of allowed backends that are specified by this function.

The possible backend names are:

  • broadway

  • macos

  • wayland.

  • win32

  • x11

You can also include a * in the list to try all remaining backends.

This call must happen prior to functions that open a display, such as func@Gdk.Display.open, gtk_init(), or gtk_init_check() in order to take effect.

Parameters

backends

a comma-separated list of backends
