Overrides the `GtkEditable` properties for class.
This is a helper function that should be called in class_init, after installing your own properties.
Note that your class must have "text", "cursor-position", "selection-bound", "editable", "width-chars", "max-width-chars", "xalign" and "enable-undo" properties for this function to work.
To handle the properties in your set_property and get_property functions, you can either use [[email protected]_set_property]
and [[email protected]_get_property] (if you are using a delegate), or remember the first_prop offset and add it to
the values in the [[email protected]] enumeration to get the property IDs for these properties.
