get_intrinsic_height

Gets the preferred height the this would like to be displayed at.

Consumers of this interface can use this to reserve enough space to draw the paintable.

This is a purely informational value and does not in any way limit the values that may be passed to [method@Gdk.Paintable.snapshot].

If the this does not have a preferred height, it returns 0. Negative values are never returned.

Parameters:

this	a `GdkPaintable`

Returns:

the intrinsic height of this or 0 if none.
