Calculates the internal constraints of a pane.
A CAPI pane or layout.
The generic function
calculates the internal constraints for
according to the sizes of its children, and sets these values into
's geometry cache.
When the pane does not scroll in the relevant dimension, all the geometry hints (
and so on) override the values that are computed by
See "Width and Height Constraints" in the
CAPI User Guide
for description of internal and external constraints.
The CAPI calls
for each pane and layout that it displays.
When creating your own layout, you should define a method for
that sets the values of the following geometry slots based on the constraints of its children.
The minimum width of pane.
The maximum width of pane.
The minimum height of pane.
The maximum height of pane.
The constraints of any CAPI element can be found by calling get-constraints.
