Function gtk4::init

source ·
pub fn init() -> Result<(), BoolError>
Expand description

Tries to initialize GTK.

Call either this function or Application::new before using any other GTK functions.

Note that this function calls gtk_init_check() rather than gtk_init(), so will not cause the program to terminate if GTK could not be initialized. Instead, an Ok is returned if the windowing system was successfully initialized otherwise an Err is returned.
