Line Widget Basics

You can add the Line Widget only to the VBox form. This widget will be available in the Widgets palette when the VBox form is selected in the app canvas.

Creating a Line Using a Constructor: kony.ui.Line

var myline = new kony.ui.Line(basicConf, layoutConf, pspConf);

• basicConf is an object with basic properties.
• layoutConf is an object with layout properties.
• pspConf is an object with platform specific properties.

Note: The configuration properties should be passed only in the respective configuration objects otherwise they are ignored

Example

//Defining the properties for a Line with id:"line".
var lineBasicConf = {
    id: "line1",
    skin: "gradlblskin",
    isVisible: true
};

var lineLayoutConf = {
    margin: [0, 0, 0, 0],
    padding: [3, 3, 3, 3],
    thickness: 25
};

var linePSPConf = {};

//Creating the Line.
var line1 = new kony.ui.Line(lineBasicConf, lineLayoutConf, linePSPConf);

//Reading the id property of Line widget.
alert("Line id ::"+line1.id);

When do I use a Line Widget?

You can use a Line widget to indicate a separator between two widgets which are placed side-by-side or placed one below the other.

Behavior of a Line Widget

• Orientation of a line can be horizontal or vertical. The orientation of the line depends on the widget it is placed in.

Customizing Appearance

You can customize the appearance of the Line widget using the following properties:

• margin: Defines the space around a widget.
• thickness: Defines the thickness of the line in pixels.
