Issues creating gtk4 dropdown

[Will]

Hello, I’m having trouble understanding the documentation for dropdowns in gtk4 and all the help online seems to be for combo boxes which are now deprecated. This is my code:

const char* options = { “1”, “5”, “7”, “9” };
//seg fault on this line
GtkWidget* dropdown0 = gtk_drop_down_new_from_strings (options);

Any help would be appreciated.

The array of strings must be NULL-terminated:

Use this, instead:

GtkWidget *dropdown =
  gtk_drop_down_new_from_strings ((const char *[]) {
                                    "1",
                                    "5",
                                    "7",
                                    "9",
                                    NULL,
                                  });

Wow! That was a real head-scratcher, thanks!

(const char *[]) {
                                    "1",
                                    "5",
                                    "7",
                                    "9",
                                    NULL,
                                  });

Exactly what I was looking for.
