measure

Description:

public virtual void measure (Orientation orientation, int for_size, out int minimum, out int natural, out int minimum_baseline, out int natural_baseline)

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

As an example, if orientation is gtk_orientation_horizontal and for_size is 300, this functions will compute the minimum and natural width of this if it is allocated at a height of 300 pixels.

See [GtkWidget’s geometry management section](class.Widget.html#height-for-width-geometry-management) for a more details on implementing `GtkWidgetClass.measure()`.

Parameters:

this	A `GtkWidget` instance
orientation	the orientation to measure
for_size	Size for the opposite of `orientation`, i.e. if `orientation` is gtk_orientation_horizontal, this is the height the widget should be measured with. The gtk_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
minimum_baseline	location to store the baseline position for the minimum size, or -1 to report no baseline
natural_baseline	location to store the baseline position for the natural size, or -1 to report no baseline
