gtkBuilderValueFromString

Description

This function demarshals a value from a string. This function calls gValueInit() on the value argument, so it need not be initialised beforehand.

Arguments

`object`	a `GtkBuilder`
`pspec`	the `GParamSpec` for the property
`string`	the string representation of the value
`.errwarn`	Whether to issue a warning on error or fail silently

Details

This function can handle char, uchar, boolean, int, uint, long, ulong, enum, flags, float, double, string, GdkColor and GtkAdjustment type values. Support for GtkWidget type values is still to come.

Upon errors FALSE will be returned and error will be assigned a GError from the GTK_BUILDER_ERROR domain. Since 2.12

Value

A list containing the following elements:

`retval`	[logical] `TRUE` on success
`value`	the `R object` to store the result in
`error`	return location for an error, or `NULL`. [ allow-none ]
