how to send text field values from one qml to another qml page in cascades blackberry - qt

Question

I am new to development on BB cascades. I've created two QML Pages. I want to pass data from one QML Page to another.
I want to pass the values phonenumber(id:phonenumber) and amount ( id:amount) from mobile.qml to payment.qml.
Please anyone help me out. Thank you in advance.
Mobile.qml:
import bb.cascades 1.4
import bb.data 1.0
Page {
onCreationCompleted: {
getData()
getCircle()
}
Container {
background: backgroundPaint.imagePaint
attachedObjects: [
ImagePaintDefinition {
id: backgroundPaint
imageSource: "asset:///images/background.png"
}
]
TextField {
id:phonenumber
hintText: "Enter Phone Number"
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
topMargin: ui.du(3)
// On text change the label text is updated.
input
{
keyLayout: KeyLayout.Text
}
}
TextField {
id:amount
hintText: "Enter Amount"
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
topMargin: ui.du(3)
// On text change the label text is updated.
input
{
keyLayout: KeyLayout.Text
}
}
Button {
id: newButton
horizontalAlignment: HorizontalAlignment.Center
verticalAlignment: VerticalAlignment.Center
topMargin: ui.du(3)
text: "Recharge"
appearance: ControlAppearance.Primary
color: Color.create("#F93249")
onClicked: {
var blogpage = goToWebView.createObject();
navigationPane.push(blogpage);
}
attachedObjects: ComponentDefinition {
id: goToWebView
source: "payment.qml"
}
}
}
attachedObjects: [
ComponentDefinition {
id: newOptionDef
Option {}
}
]
}
payment.qml:
import bb.cascades 1.4
Page {
Container {
background: backgroundPaint.imagePaint
attachedObjects: [
ImagePaintDefinition {
id: backgroundPaint
imageSource: "asset:///images/background.png"
}
]
}
}

Answer 1

Next time please post only code related to problem. As for your problem you can use parent as a proxy to access one item from another one.
For example, assume we have a component:
Page.qml
import QtQuick 2.4
import QtQuick.Controls 1.2
Item {
id:page
width: 200
height: 200
property int callee
function func() {
txt.text = txt.text + " (changed)"
}
Text {
id: txt
anchors.centerIn: parent
text: "click me"
MouseArea {
anchors.fill: parent
onClicked: {
page.parent.proxyFunction(page.callee);
}
}
}
}
and so Item contains several Pages:
import QtQuick 2.4
import QtQuick.Window 2.0
Window {
width: 400
height: 200
Row {
anchors.fill: parent
function proxyFunction(page) {
children[page].func();
}
Page {callee: 1}
Page {callee: 0}
}
}
So here as you can see clicking Text in one of Pages triggers changing Text in another Page.

Answer 2

In your Page add these lines:
import bb.cascades 1.4
import bb.data 1.0
Page {
id: mobilePage // ADD THIS
property string m_amount // ADD THIS
property string m_phoneNumber // ADD THIS
// the rest of the code
onClicked: { // Buttons onClick
mobilePage.m_amount = amount.text // ADD THIS
mobilePage.m_phoneNumber = phonenumber.text // ADD THIS
var blogpage = goToWebView.createObject()
navigationPane.push(blogpage)
}
}
Now in payment.qml you can use this:
console.log(mobilePage.m_amount)
console.log(mobilePage.m_phoneNumber)

Answer 3

You have to create a property in payment.qml at page level.
Page{
Id: payment
Properly string phonenumber;
Properly string amount;
Container{
Label{
Id: lblphonenumber
text: phonenumber
}
Label{
Id: lblamout
text: amount
}
}
in your main.qml you have to do this:
onClicked: {
var blogpage = goToWebView.createObject();
blogpage.phonenumber = yourvalue;
blogpage.amount = yourvalue;
navigationPane.push(blogpage);
}
This is it :)
