Declaration [src]

gtk_builder_add_from_file (
  GtkBuilder* builder,
  const char* filename,
  GError** error

Description [src]

Parses a file containing a UI definition and merges it with the current contents of builder.

This function is useful if you need to call gtk_builder_set_current_object()) to add user data to callbacks before loading GtkBuilder UI. Otherwise, you probably want gtk_builder_new_from_file() instead.

If an error occurs, 0 will be returned and error will be assigned a GError from the GTK_BUILDER_ERROR, G_MARKUP_ERROR or G_FILE_ERROR domains.

It’s not really reasonable to attempt to handle failures of this call. You should not use this function with untrusted files (ie: files that are not part of your application). Broken GtkBuilder files can easily crash your program, and it’s possible that memory was leaked leading up to the reported failure. The only reasonable thing to do when an error is detected is to call g_error().


filename const char*

The name of the file to parse.

 The data is owned by the caller of the function.
 The string is a file system path, using the OS encoding.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: gboolean

TRUE on success, FALSE if an error occurred.
