Class method
GtkWidgetClassbind_template_child_full
Declaration [src]
void
gtk_widget_class_bind_template_child_full (
GtkWidgetClass* widget_class,
const char* name,
gboolean internal_child,
gssize struct_offset
)
Description [src]
Assigns an object declared in the class template XML to be set to
a location on a freshly built instance’s private data, or
alternatively accessible via gtk_widget_get_template_child().
The struct can point either into the public instance, then you should
use G_STRUCT_OFFSET(WidgetType, member) for struct_offset, or in the
private struct, then you should use G_PRIVATE_OFFSET(WidgetType, member).
An explicit strong reference will be held automatically for the duration
of your instance’s life cycle, it will be released automatically when
GObjectClass.dispose() runs on your instance and if a nonzero struct_offset
is specified, then the automatic location in your instance public or private
data will be set to NULL. You can however access an automated child pointer
the first time your classes GObjectClass.dispose() runs, or alternatively
in GtkWidget::destroy.
If internal_child is specified, Gtk.BuildableIface.get_internal_child
will be automatically implemented by the widget class so there is no
need to implement it manually.
The wrapper macros gtk_widget_class_bind_template_child(),
gtk_widget_class_bind_template_child_internal(),
gtk_widget_class_bind_template_child_private() and
gtk_widget_class_bind_template_child_internal_private()
might be more convenient to use.
Note that this must be called from a composite widget classes class
initializer after calling gtk_widget_class_set_template().
Parameters
name-
Type:
const char*ID of the child defined in the template XML.
The data is owned by the caller of the method. The value is a NUL terminated UTF-8 string. internal_child-
Type:
gbooleanWhether the child should be accessible as an “internal-child” when this class is used in GtkBuilder XML.
struct_offset-
Type:
gssizeThe offset into the composite widget’s instance public or private structure where the automated child pointer should be set, or 0 to not assign the pointer.
