SignatureCapture Properties

The properties for SignatureCapture widget are:

---

accessMode Property

---

Specifies how the captured image must be stored.

Syntax

accessMode

Type

Number

Read/Write

Read + Write

Remarks

The default value for this property is CAMERA_IMAGE_ACCESS_MODE_PRIVATE.

The available options are:

• CAMERA_IMAGE_ACCESS_MODE_PRIVATE: The captured image is stored as an Image on the device and will not be accessible to any other application on the device and remain private to the application.
• CAMERA_IMAGE_ACCESS_MODE_PUBLIC: The captured image is stored on the device as a Image and is accessible to all the applications on the device. For example, the captured images are accessible in ImageGallery.
• CAMERA_IMAGE_ACCESS_MODE_INMEMORY: The captured camera image is stored in memory and is never written to the disk.

Example

//Sample code to set the accessMode property of a SignatureCapture widget.

frmSCapture.mySCapture.accessMode=constants.CAMERA_IMAGE_ACCESS_MODE_INMEMORY;

---

anchorPoint Property

---

Specifies the anchor point of the widget bounds rectangle using the widget's coordinate space.

Syntax

anchorPoint

Type

JSObject

Read/Write

Read + Write

Remarks

The value for this property is a JavaScript dictionary object with the keys "x" and "y". The values for the "x" and "y" keys are floating-point numbers ranging from 0 to 1. All geometric manipulations to the widget occur about the specified point. For example, applying a rotation transform to a widget with the default anchor point causes the widget to rotate around its center.

The default value for this property is center ( {"x":0.5, "y":0.5} ), that represents the center of the widgets bounds rectangle. The behavior is undefined if the values are outside the range zero (0) to one (1).

Example

Form1.widget1.anchorPoint = {
    "x": 0.5,
    "y": 0.5
};

Platform Availability

---

bottom Property

---

This property determines the bottom edge of the widget and is measured from the bottom bounds of the parent container.

In freeform layout, the distance is measured from the bottom edge of the parent container. In flow-vertical layout, the value is ignored. In flow-horizontal layout, the value is ignored.

The bottom property is used only if the Height property is not provided.

Syntax

This property specifies the stack order of a widget. A widget with a higher zIndex is always in front of a widget with a lower zIndex.

The zIndex property is used to set the stack, or layer order of a widget. Widgets with higher values will appear “over”, or “on top of” widgets with lower values. Widgets layered over other widgets will override any interaction events tied to widgets beneath. Modifying the zIndex does not modify the order of the widgets in the Volt MX Iris hierarchy, inside of a flexContainer or form. The zIndex property accepts only positive values.

Remarks

The default value for this property is 1.

Note: Modifying the zIndex does not modify the order of the widgets inside the FlexContainer. If zIndex is same for group of overlapping widgets then widget order decides the order of overlapping. The last added widget is displayed on top.

From Volt MX Iris V9 SP2 FP7, developers can configure the Z Index value for a Responsive Web app as Auto or Custom. When the selected Z Index value is Auto, the default Z Index value of 1 is applied. When the selected Z Index value is Custom, developers can specify a desired numeric value.

Prior to the V9 SP2 FP7 release, the default value for the Z Index was 1. When developers imported any third-party libraries with the Z index set as Auto, content overflow was disabled as the value of Auto is less than 1.

Note: The Z Index value Auto is supported only when the Enable JS Library mode is configured as unchecked.

For existing components, the value of the Z Index is configured as 1 for the Native channel. For the Responsive Web channel, the Z Index will be set as Custom with 1 as the value.

For new components, the value of the Z Index is configured as 1 for the Native channel. For the Responsive Web channel, the Z Index will be set as Auto or 1 based on the project level settings.

Note: If ModalContainer property is set to true in any of the FlexContainer widget, the Z Index value of that container and all of its parent containers should be set to Custom.

voltmx.flex.ZINDEX_AUTO : Constant to configure the Z Index value as auto programmatically.

//Sample code to set the ZIndex value to Auto  
 var flx = new voltmx.ui.FlexContainer({ 
  "id": "flx"
  "zIndex": voltmx.flex.ZINDEX_AUTO
});

//Sample code to set the ZIndex value to Auto
flx.zIndex = voltmx.flex.ZINDEX\_AUTO;

Example

//Sample code to set the zIndex property for widgets.  
frmHome.widgetID.zIndex = 300;
