To implement the widget-specific logic, you can access the parent canvas using the '''cmdarg()''' API: | |||
<syntaxhighlight lang="php"> | |||
var my_canvas = canvas.get( cmdarg() ); # this will get a handle to the parent canvas | |||
var root = my_canvas.createGroup(); | |||
var text = root.createChild("text") | |||
.setText("some custom canvas widget") | |||
.setTranslation(10, 30) | |||
.setAlignment("left-top") | |||
.setFontSize(20) | |||
.setFont("LiberationFonts/LiberationSans-Regular.ttf") | |||
.set("max-width", 380) | |||
.setColor(1,0,0); | |||
