add_from_resource
Description:
Parses a resource file containing a UI definition and merges it with the current contents of this.
This function is useful if you need to call [method@Gtk.Builder.set_current_object] to add user data to callbacks before loading GtkBuilder UI. Otherwise, you probably want [ctor@Gtk.Builder.new_from_resource] instead.
If an error occurs, 0 will be returned and throws will be assigned a `GError` from the gtk_builder_error, g_markup_error or g_resource_error domain.
It’s not really reasonable to attempt to handle failures of this call. The only reasonable thing to do when an error is detected is to call error.
Parameters:
| this |
a `GtkBuilder` |
| resource_path |
the path of the resource file to parse |
Returns:
|
true on success, false if an error occurred |
