SwitchList

This complex component allows to define a set of branches that can be activated one after the other.

Constructor

SwitchList <id> (bool loop) {
  Component <id> {...}
  ...
}
        

The branches of a SwitchList are classic components, that is containers to which any kind of processes can be added. The SwitchList has three predefined children: next, previous, index that allow to activate a new branch, respectively, the next, the previous or the one designated by the index. In each case, the current branch is deactivated and the new one is activated. If the loop argument is set to true, the next and previous signals will loop over the branches.

Warning

A switch list branch can't have loop, next, previous or index as a name

Action

Activates the fist branch of the SwitchList.

Predefined children

• BoolProperty: loop specifies if the switch can loop over its branches.
• Spike: next goes to the next branch.
• Spike: previous goes to the previous branch.
• IntProperty: index goes to the branch designated by the value of index.

Example

use core
use base
use gui

_main_
Component root {
  Frame f ("myButton", 0, 0, 500, 500)
  Exit quit (0, 1)
  f.close->quit
  SwitchList blink (1) {
    Component _ {
      FillColor red (255, 0, 0)
      Rectangle r (0, 0, 100, 70, 0, 0)
    }
    Component _ {
      FillColor green (0, 255, 0)
      Rectangle r (0, 0, 100, 70, 0, 0)
    }
  }
  Clock cl (500)
  cl.tick->blink.next
}
