How to change the cursor to a watch in GTK for C?

Question

I'm using the C-style GTK functions in C++ and I can't figure out how to set the cursor for the main window.

Answer 1

Use gdk_window_set_cursor() on a GdkCursor created by gdk_cursor_new_from_name().

To get the GdkWindow of a GtkWindow you can use gtk_widget_get_window() because GtkWindow is a subclass of GtkWidget.

Answer 2

Use gdk_set_cursor()

on a GdkCursor created by gdk_cursor_new()
