QR code
Creates a graphical image in the form of a two-dimensional bar code which, when read by a QR scanner, directs you to a particular web site.
Appearance
Label placement: The label position.
{Top | Left}		 LabelPlacement
Label width: The width of the label in px, % or em.\r\nFor example\: 50px, 20%, 0.4em. If no unit is specified, px is assumed. String
Width: Width of the QRCode view String
Height: Height of the QRCode view String
Background image URL: The background image URL for the QR view. String
Behavior
Error correction level: There are 4 error correction levels used for QR codes, with each one adding different amounts of backup data depending on how much damage the QR code is expected to suffer in its intended environment, and hence how much error correction may be required\:\r\nLevel L up to 7% damage\r\nLevel M up to 15% damage\r\nLevel Q up to 25% damage\r\nLevel H up to 30% damage
{Level L - up to 7% damage | Level M - up to 15% damage | Level Q - up to 25% damage | Level H - up to 30% damage}		 QRErrorCorrectionLevel
Formula
QR code formula: The formula or expression to calculate the QR code value. String
Events
On Load:
Description: This event is fired when the QRCode is loaded.
Example: 
me.setQRCode("www.salientprocess.com")
On Change:
Description: This event is fired when the QRCode is changed.
Example: 
${Text1}.setText(oldQRCode); ${Text2}.setText(newQRCode);
Context Variables newQRCode {string} oldQRCode {string}

Methods:
Inherited addClass(name, [replaced])
Add/replace CSS class(es) for this control
NameTypeDefaultDescription
name{string}CSS class name(s) to add to the control. Separate class names by a space if more than one class.
replaced{string}CSS class name(s) to be replaced by the first argument. Separate class names by a space if more than one class.
Example
Button.addClass("green");
getBackgroundImageURL() Returns: {string}
Get configured backgroundImageURL for QRCode control
Inherited getData() Returns: {Object}
Retrieve bound data associated this view/control. Only works for views/controls with bound data.
Example
var dec1 = MyDecimal.getData();
getErrorCorrectionLevel() Returns: {string}
Get configured errorCorrectionLevel for QRCode control
getHelpText() Returns: {string}
Get help text associated with QRCode control
getLabel() Returns: {string}
Get label associated with QRCode control
getLabelPlacement() Returns: {string}
Get label placement for control. NOTE: This always returns the label placement as set, to avoid ambiguity always set the label placement using "T"|"L"
getLabelWidth() Returns: {string}
Get label width of QRCode control (e.g. 50px, 20%, 2em - omitting the unit assumes px)
getQRCode() Returns: {string}
Get QRCode for QRCode control
getType() Returns: {string}
Get descriptive string representing the type of control
getWidth() Returns: {string}
Get configured width for QRCode control (including unit)
Inherited hide(collapseFlag)
Hide this view/control
NameTypeDefaultDescription
collapseFlag{boolean}Set to true to collapse the view (equivalent to a view setting of "NONE")
Example
MyView.hide();
Inherited isBound() Returns: {boolean}
Indicates bound status of control.
Inherited isEnabled() Returns: {boolean}
Checks if the view is enabled or not
Example
var enabled = MyView.isEnabled();
isLabelVisible() Returns: {boolean}
Get label visibility for QRCode control
Inherited isValid() Returns: {boolean}
Returns the valid status as last set by the setValid() method.
Example
var valid = MyView.isValid();
Inherited isVisible() Returns: {boolean}
Checks whether or not view is visible
Example
var visible = MyView.isVisible();
Inherited propagateUpValueChange(event) Returns: {boolean}
Propagates value change of control up through parent views
NameTypeDefaultDescription
event{Event}Value change event (usually an onchange event)
Example
MyView.propagateUp(event);
Inherited recalculate()
Only for formula-enabled views!
Explicitly triggers the re-evaluation of the formula

Text1.recalculate();
//If the formula for Text1 is: new Date().toString(), Text1 is updated to the current date/time
setBackgroundImageURL(height)
Set backgroundImageURL of QRCode control
NameTypeDefaultDescription
height{string}backgroundImageURL
Inherited setEnabled(enabled, required)
Enable/disable this view/control
NameTypeDefaultDescription
enabled{boolean}Enabled/read-only flag (true to enable view, false to disable/make read-only)
required{boolean}Enable/disable required field flag for control
Example
MyView.setEnabled(false); //Make MyView read-only
setErrorCorrectionLevel(level)
Set errorCorrectionLevel of QRCode control
NameTypeDefaultDescription
level{string}"L"=Level L | "M"="Level M | "Q"=Level Q | "H"=Level H
setHeight(height)
Set height of QRCode control (e.g. 50px, 20%, 2em - omitting the unit assumes px)
