get_item_attribute

Description:

public bool get_item_attribute (int item_index, string attribute, string format_string, ...)

Queries item at position item_index in this for the attribute specified by attribute.

If the attribute exists and matches the VariantType corresponding to format_string then format_string is used to deconstruct the value into the positional parameters and true is returned.

If the attribute does not exist, or it does exist but has the wrong type, then the positional parameters are ignored and false is returned.

This function is a mix of get_item_attribute_value and @get, followed by a g_variant_unref. As such, format_string must make a complete copy of the data (since the Variant may go away after the call to g_variant_unref). In particular, no '&' characters are allowed in format_string.

Parameters:

this	a MenuModel
item_index	the index of the item
attribute	the attribute to query
format_string	a Variant format string
...	positional parameters, as per `format_string`

Returns:

true if the named attribute was found with the expected type
