TuiSolve

Returns the sizes that constraints give a total, adding up to exactly that total.

Syntax

TuiSolve( byval total as int32, byref cs as TuiConstraintArray ) as Array( of int32 )

Description

The raw sizes, if you want to lay something out yourself. The rule is stated exactly so the result is deterministic: fixed constraints first, FILL shares the remainder by weight, odd cells go to the earlier slots, and over-subscription shrinks right to left. The same input always gives the same answer, on both platforms.

Example

#import "std/containers"
#import "std/tui"
using tui, containers

dim as TuiConstraintArray cs
cs.Push( TuiLength( 3 ) )
cs.Push( TuiFill( ) )
cs.Push( TuiLength( 1 ) )

dim as Array( of int32 ) s = TuiSolve( 24, cs )
print s[0], s[1], s[2]            '' 3 20 1

dim as int32 total_ = 0
for i as int32 = 0 to s.Count( ) - 1 : total_ += s[i] : next
print total_                      '' 24 -- always exactly the total
