JavaFX properties bindings

This article list the implementation-dependant bindings that have been defined on J661 on widgets properties. These bindings can be used for example to define animations on widgets.

Bindings properties

Java class	Property name	Property ARINC ID	Property type	Usage
javafx.scene.Node	opacity	0xB003	float property	Allows to change the opacity of a Node
javafx.scene.shape.Shape	strokeWidth	0xB800	float property	Allows to change the width of a Shape
javafx.scene.shape.Shape	stroke	0xB8001	color property	Allows to change the border color (stroke) of a Shape. See Color properties representation
javafx.scene.shape.Shape	fill	0xB002	color property	Allows to change the fill color of a Shape. See Color properties representation
javafx.scene.layout.Region	fill	0xB002	color property	Allows to change the fill color of a Region. See Color properties representation
javafx.scene.layout.Region	stroke	0xB002	color property	Allows to change the border color (stroke) of a Region. See Color properties representation

Color properties representation

The conversion from a float value to a Color uses the following algorithm: The value cast as int is considered to be the RGBA value of the color, with:

• the two first bytes being the red component
• the two next bytes being the green component
• the two next bytes being the blue component
• the two last bytes being the alpha component

Usage examples

Changing the border width of a rectangle

The following Definition File specifies an animation which changes the border width of a rectangle:

      <a661_widget name="gpRectangle" type="A661_GP_RECTANGLE">
         <model>
            <prop name="WidgetIdent" value="1" />
            <prop name="Anonymous" value="A661_FALSE" />

      </a661_widget>

Changing the opacity of a Panel

The following Definition File specifies an animation which changes the opacity of a Panel:

      <a661_widget name="panel" type="A661_PANEL">
         <model>
            <prop name="WidgetIdent" value="1" />
            <prop name="Enable" value="A661_TRUE" />
            <prop name="Visible" value="A661_TRUE" />
            <prop name="PosX" value="2000" />
            <prop name="PosY" value="2000" />
            <prop name="SizeX" value="5000" />
