Sorter

This component sorts the children of a Container (i.e. a Component or a List) according to a specified property.

Constructor

          Sort <id> (Process container, string path_and_name_of_the_property)
        

Action

Sort the children of the given container according to the given path.

Predefined children

• BoolProperty: ascending if true, sorts in the ascending order, otherwise sorts in the descending order.
• TextProperty: spec path and name of the property used for the sort.
• Spike: sort triggers the sort.

Example

use core
use base
use gui

_main_
Component root {
  Frame f ("my frame", 0, 0, 400, 600)
  Exit ex (0, 1)
  f.close -> ex
  FillColor _ (200, 50, 50)
  OutlineColor _ (100, 100, 250)
  FillOpacity _ (0.5)
  List l {
    Rectangle r1 (0, 0, 100, 40, 0, 0)
    Rectangle r2 (0, 10, 50, 60, 0, 0)
    Rectangle r3 (0, 20, 150, 90, 0, 0)
  }
  Sorter sorter (l, "width")
  Timer t (1000)
  AssignmentSequence change (1) {
    "height" =: sorter.spec
  }
  t.end->change, sorter.sort
  sorter.sort->(l) {
    int y = 10
    for (int i = 1; i <= l.size; i++) {
      l.[i].y = y
      y = y + 70
    }
  }
