Builder.addFromString

uint addFromString(string buffer)

Parses a string containing a [GtkBuilder UI definition][BUILDER-UI] and merges it with the current contents of builder.

Most users will probably want to use [gtk.builder.Builder.newFromString].

Upon errors 0 will be returned and error will be assigned a #GError from the #GTK_BUILDER_ERROR, #G_MARKUP_ERROR or #G_VARIANT_PARSE_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 g_error().

Parameters

buffer the string to parse

Returns

A positive value on success, 0 if an error occurred

Throws

[ErrorWrap]
