Cascades Development

[discnick]

Hello,

I am trying to implement the functionality provided by the ComponentDefinition class as shown on the following page,

https://developer.blackberry.com/cascades/reference/bb__cascades__qmlcomponentdefinition.html

Unfortunately an error occured when running the application and loading the qml file . The console output follows,

ComponentDefinition is not a type

Any advices anyone?

Yes I too got the same error.

I also tried changing ComponentDefinition with QmlComponentDefinition as analogous to ImagePaintDefinition when used with attachedObjects property to define an ImagePaint to draw a background image for the respective control.

This too results in the same error

Error 1    A colon after attachedObject property was missing

Error 2    Padding property is not available for Container object

Error 3    Actually no such classes named ComponentDefinition and QmlComponentDefinition were found in API References like we have class ImagePaintDefinition to define an ImagePaint in QML when used inside attachedObjects property.

Hi discnick,

I tried making a sample for using Componentdefinition provided on the same link you've referred: https://developer.blackberry.com/cascades/reference/bb__cascades__qmlcomponentdefinition.html

Following is the code & I'm getting No such error like "Component Definition is not a Type" while running. The code is working successfully in my beta3 device. 

import bb.cascades 1.0

Page {
    Container {
        Button {
            text: "Click to create bordered text"
            onClicked: {
                // creates borderedTextComponent control and appends it to container
                var createdControl = borderedTextComponent.createObject();
                container.add(createdControl);
                createdControl.textString = "Hello Component";
                createdControl.padding = 30;
                createdControl.textColor = Color.DarkGray;
            }
        }
        Container {
            id: container
        }
        attachedObjects: [
            ComponentDefinition {
                id: borderedTextComponent
                Container {
                    property variant borderColor: Color.Red
                    property variant fillColor: Color.White
                    property variant textColor: Color.Black
                    property string textString
                    property real padding: 10
                    background:  borderColor//Color.Black //
                    leftPadding: padding
                    rightPadding: padding
                    topPadding: padding
                    bottomPadding: padding
                    Container {
                        background: fillColor// Color.Blue
                        Label {
                            text: textString
                            textStyle.color: textColor//Color.Green //textColor
                        }
                    }
                }
            }
        ]
    }
}

 No special inclusion for any file in app.cpp. Nothing.

Sry for the delay guys.

The problem does not exist any more.

I think the problem fixed once I updated my SDK to Beta 3 ( not 100% sure though..).

@ Shubhangi : can you confirm that you are using the Beta 3?

[Shubhangi]

Hi Discnick,

How to check whether I am having beta2 or beta3?

Also How to upgrade to Beta3? Do I need to download Beta3 native SDK from Download and then install it directly on laptop?

Let me know.

Thanks and regards,

Shubhangi

Hi Shubhangi

From inside the QNX Momentics IDE , go to : Help  - About QNX Momentics IDE. On the About QNX Momentics IDE dialog check your version . The Beta 3 version number is : 10.0.9 .

In case you have not updated to Beta 3 , you should also look at this link also
