Calendar Events

doLayout Event

This event is invoked for every widget when the widget position and dimensions are computed.

Syntax

doLayout()

Read/Write

Read + Write

Remarks

This event is invoked for all the widgets placed inside flex containers. This event is invoked in the order in which the widgets are added to the widget hierarchy and expect the frame property of the widget is calculated and available for use within this event.

This event is used to set the layout properties of child widgets in the relation to self and peer widgets whose layout is not yet performed.

The number of times this event invoked may vary per platform. It is not recommended to write business logic assuming that this function is invoked only once when there is a change in positional or dimensional properties. This event will not trigger when transformations are applied though widget is moved or scaled or rotated from its original location.

Example



//Sample code to set doLayout event callback to a button widget.
/*This code changes the top property of button2 and makes it appear below button1.*/
myForm.button1.doLayout=doLayoutButton1;


function doLayoutButton1(){
      
    myForm.button2.top = myForm.button1.frame.height;
}

onAppointmentTap Event

This event is triggered when you tap any of the existing appointments in the following view types:

CALENDAR_VIEW_TYPE_DAY_VIEW
CALENDAR_VIEW_TYPE_WEEK_VIEW
CALENDAR_VIEW_TYPE_MONTH_VIEW

Syntax

onAppointmentTap()

Remarks

The details of the appointment tapped is returned with a unique id in the callback.


{
  "uniqueid":"fc309",
  "startDate":"2014-10-12 00:00:00",
  "endDate":"2014-10-13 04:00:00",
  "Subject":"Travel to Europe",

  "skin":{"cellcolor":"#FFF09609"},
  "info":{}
}

The unique id, identifies the appointment displayed in these calendar views.

onBlur Event

An event that accepts a callback function as an input and executes the functionality defined in the callback function when the widget is blurred.

Syntax

onBlur()

Callback function

A function that contains the logic to be implemented when the widget is blurred.

Read/Write

Read + Write

Remarks

Assign a null value to the onBlur event of a widget to remove the blur effect on the widget.

Example

 

//This is a generic event that is applicable for various widgets.
/*Here, we have shown how to use the onBlur event for a Button widget. You need to make a corresponding use of the onBlur event for other applicable widgets.*/

onDone Event

This event is triggered when the Done or Enter button is clicked or tapped after the calendar opens.

Syntax

onDone()

Read/Write

Read + Write

Remarks

In Desktop Web platform, this event is fired when the enter key is pressed when the Calendar widget is in focus.
In iOS platform, the Done button is available only when the value of the inputAccessoryViewType property is CALENDAR_INPUTACCESSORYVIEW_NEXTPREV. So in iOS platform, the onDone event is fired only when the value of inputAccessoryViewType property is CALENDAR_INPUTACCESSORYVIEW_NEXTPREV.

Example



//Sample code to set the onDone event callback to a Calendar widget.

frmCalendar.myCalendar.onDone=onDoneCallback;

function onDoneCallback(calendarWdg){
      //Write your logic here.
}

This event is applicable only when the viewType is set to CALENDAR_VIEW_TYPE_DAY_VIEW. The arguments holds the value for the date time details of the empty cell being tapped in the following format "dd-MM-yyyy HH:mm". For example, 13-10-2014 10:20.

Example



//Sample code to set onEmptyCellTap event callback to Calendar widget.

frmCalendar.myCalendar.onEmptyCellTap=onEmptyCellTapCallBck;

function onEmptyCellTapCallBck(calendar){

onFocus Event

An event that accepts a callback function as an input and executes the functionality defined in the callback function when the widget is in focus.

Syntax

onFocus()

Input Parameters

Callback function

A function that contains the logic to be implemented when the widget is in focus.

From the V9 Service Pack 7 Fixpack 6 release, the callback function of the onFocus Event contains a new parameter, activeElement. The activeElement parameter specifies the widget that is currently in focus.

Read/Write

Read + Write

Remarks

Assign a null value to the onFocus event of a widget to remove focus from the widget.

Example

 

//This is a generic event that is applicable for various widgets.
/*Here, we have shown how to use the onFocus event for a Button widget. You need to make a corresponding use of the onFocus event for other applicable widgets.*/

frmButton.myButton.onFocus = onFocusCallBack;

onKeyPress Event

This event takes a callback as an input that is invoked by the platform when the user presses a key (on the keyboard).

Syntax

onKeyPress(eventObject, eventPayload, context)

Input Parameters

eventObject:

An Object that contains the instance of the widget that triggered the onKeyPress event.

eventPayload:

An Object that contains information about the keyboard interactions. Based on the key that the user presses, the value of the eventPayload varies as follows:

Key	Description
altKey	Returns a boolean value. The value is true when the Alt key (Option key on macOS systems) is pressed.
ctrlKey	Returns a boolean value. The value is true when the Ctrl key is pressed.
shiftKey	Returns a boolean value. The value is true when the Shift key is pressed.
metaKey	Returns a boolean value. The value is true when the meta key ( windows key ⊞ on windows systems, command key ⌘ on macOS systems) is pressed.
capsLock	Returns a boolean value. The value is true when the capsLock key is turned on.
keyCode	Returns the ASCII code of the key pressed .
preventDefault	Returns a function. This function can be invoked to prevent the default action of the widget.

context:

An Object that represents information about the row that contains the target widget that triggered the onKeyPress event.

rowIndex: The index of the row that contains the target widget for a Segment widget.

itemIndex: The index of the row that contains the target widget for a CollectionView widget.

sectionIndex: The index of the section that contains the target widget.

widgetInfo: The widget reference of the Segment or CollectionView widget.

Read/Write

Read + Write

Remarks

The onKeyPress event is not linked with native keypress event, i.e both the events are different.
For widgets (such as TextBox and TextArea) that support both the onKeyDown and onKeyPress events, the onKeyDown event takes higher priority.
If a widget has both the onKeyDown and onKeyPress events configured, the onKeyDown event is invoked first, followed by the onKeyPress event.
The Web Framework provides support for both the onKeyDown and onKeyPress events on the TextBox and TextArea widgets. However, Temenos recommends that you use only one of the events for a widget.

Example



/*This event is triggered in both TextBox and TextArea widgets for Android platform.*/

/*This example demonstrates how to set an onKeyPress event callback to a Button widget that is placed inside form


frmButton.myButton.onKeyPress = onKeyPressCallBack;

function onKeyPressCallBack(eventObject, eventPayload) {
    console.log('onKeyPress event triggered');
}

onScrollWidgetPosition Event

This event callback is invoked by the platform when the widget location position gets changed on scrolling. The onScrollWidgetPosition event returns the positional coordinates of the widget's location with respect to the screen (screenX and screenY) and the parent container (frameX and frameY). This event is invoked asynchronously, and is not available for FlexForm widget.

Syntax

onScrollWidgetPosition()

Example



var LabelWdg = new kony.ui.Label(basicConf, layoutConf, pspConf);
form.add(LabelWdg);
LabelWdg.onScrollWidgetPosition = onScrollWidgetPositionCallBack;

function onScrollWidgetPositionCallBack(wdg, screenX, screenY, frameX, frameY) { //wdg : Widget that is registered for onScrollWidgetPosition.
    /*screenX : Position of widget with respect to 
the screen's X - coordinates (after downsizing the navigation bar and status bar).*/
    /*screenY : Position of widget with respect to the screen's Y - 
coordinates (after downsizing the navigation bar and status bar).*/
    //frameX : Position of widget with respect to parent container's X- coordinates.
    //frameY : Position of widget with respect to parent container's Y- coordinates.
