Widget.measure

void measure(gtk.types.Orientation orientation,  int  forSize,  out  int  minimum,  out  int  natural,  out  int  minimumBaseline,  out  int  naturalBaseline)

Measures widget in the orientation orientation and for the given for_size.

As an example, if orientation is [gtk.types.Orientation.Horizontal] and for_size is 300, this functions will compute the minimum and natural width of widget if it is allocated at a height of 300 pixels.

See GtkWidget’s geometry management section for a more details on implementing GtkWidgetClass.measure().

Parameters

`orientation`	the orientation to measure
`forSize`	Size for the opposite of orientation, i.e. if orientation is [gtk.types.Orientation.Horizontal], this is the height the widget should be measured with. The [gtk.types.Orientation.Vertical] case is analogous. This way, both height-for-width and width-for-height requests can be implemented. If no size is known, -1 can be passed.
`minimum`	location to store the minimum size
`natural`	location to store the natural size
`minimumBaseline`	location to store the baseline position for the minimum size, or -1 to report no baseline
`naturalBaseline`	location to store the baseline position for the natural size, or -1 to report no baseline
