Use setSeconds(); to close my splash screen in blackberry cascade - blackberry

Question

Well, Here I have a screen which I want to get close after 2-3 Seconds. For that I am using setDate() method.
I am very new to this Blackberry Cascade QML programming. I want to attach 1 more splash screen, so for that reason I want to use timer to close and open the sheet according to seconds.
Any help will be appreciated.
Thanks in advance.
I have worked on the following code.
import bb.cascades 1.0
import bb.cascades.pickers 1.0
Page
{
Container
{
background: Color.Transparent
//Todo: fill me with QML
onCreationCompleted:
{
mysheet1.open();
new Date();
**Error is shown in for loop**
for(Date.setSeconds(1),Date.setSeconds()<=5 , Date.setSeconds()+1)
{
if(Date == 5)
{
mysheet1.closed();
mysheet2.open();
}
}
}
attachedObjects:
[
Sheet
{
id: mysheet1
peekEnabled: false
Page
{
Container
{
background: Color.Transparent
ImageView
{
horizontalAlignment: HorizontalAlignment.Fill
verticalAlignment: VerticalAlignment.Fill
imageSource: "asset:///splash1.png"
}
}
}
}
]
}
Context Invokable: Date Date(...)
The Date object is used to work with dates and times.
Date objects are created with the new Date() constructor.
There are four ways of initiating a date:
new Date() // current date and time (or)
new Date(milliseconds) //milliseconds since 1970/01/01 (or)
new Date(dateString) (or)
new Date(year, month, day, hours, minutes, seconds, milliseconds)
Invokable: number setSeconds(number sec)
Sets the seconds of a date object.

Answer 1

It will use a lot of process for some seconds. But there is no setInterval in QML.
The best solution is using a C++ class, TimeManager.cpp with a QTimer:
To expose the C++ method to QML you can register as a ContextProperty when the QML is instanciated:
QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);
qml->setContextProperty("TimeManager", new TimeManager());
And declare the method:
Q_INVOKABLE void callLater(int milliSeconds, QObject* sloter);
The implementation:
void TimeManager::callLater(int milliSeconds, QObject* sloter){
QTimer::singleShot(milliSeconds, sloter, SLOT(timerEnd()));
}
And the QML:
onCreationCompleted: {
TimeManager.callLater(2500, this);
}
onTimerEnd: {
mysheet1.closed();
}

Here is sample code of Timer.
import bb.cascades 1.0
import my.timer 1.0
Page {
Container {
layout: DockLayout {
}
onCreationCompleted: {
mTimer.start();
}
ImageView {
id: mImageViewIcon
horizontalAlignment: HorizontalAlignment.Fill
verticalAlignment: VerticalAlignment.Fill
imageSource: "asset:///images/splash.png"
}
attachedObjects: [
QTimer {
id: mTimer
interval: 2000
onTimeout: {
//Push New Page here
}
}
]
}
}
Don't forgot to add below line in main.cpp
qmlRegisterType<QTimer>("my.timer", 1, 0, "QTimer");
