Sets entry’s inner-border property to border, or clears it if
null is passed.
Use the standard border and padding CSS properties (through objects like GtkStyleContext and GtkCssProvider
); the value set with this function is ignored by Entry.
The inner-border is the area around the entry’s text, but inside its frame.
If set, this property overrides the inner-border style property. Overriding the style-provided border is useful when you want to do in-place editing of some text in a canvas or list widget, where pixel-exact positioning of the entry is important.
