Sets whether the hexpand flag (see gtk_widget_get_hexpand()) will
be used.
The hexpand-set property will be set automatically when you call
gtk_widget_set_hexpand() to set hexpand, so the most likely
reason to use this function would be to unset an explicit expand
flag.
If hexpand is set, then it overrides any computed
expand value based on child widgets. If hexpand is not
set, then the expand value depends on whether any
children of the widget would like to expand.
There are few reasons to use this function, but it’s here
for completeness and consistency.
