Hi all,

I want to share QString data using Invocation. Following is what the snippet  should be for using Invocation concept: 

Button{

text: "Share"

onClicked: {
invoke.trigger("bb.action.SHARE")
}
attachedObjects: [
Invocation {
id: invoke
query: InvokeQuery {
mimeType: "text/txt"
uri: "Hello World"
invokeActionId: "bb.action.SHARE"
}
}
]

}

I don't get any error as this Invocation Framework is not function now in beta3 of BB10, but the property we have to provide is uri over here. i.e. QUrl. Isn;t there any other way apart from providing filepath for sharing??

Thanks in advance.

You should be using the data parameter of invocation instead of the uri parameter. https://developer.blackberry.com/cascades/reference/bb__cascades__invokequery.html#data

Hi, 

Seeing https://developer.blackberry.com/cascades/reference/bb__cascades__invocation.html I had tried data property as well. The documentation and the given example snippet guided me to use data property. Folliwing is what I had tried in my QML file.

Invocation {
id: invoke
query: InvokeQuery {
mimeType: "text/txt"
data: "Hello World"
invokeActionId: "bb.action.SHARE"
}

}

In this case, I get QML parsing Error stating: "Type mismatch of value of the 'data' property. Expecting QByteArray and found string"

try data: ["MyString"]

then it's an Array ;-)

Hi,

I tried data: ["mystring"]  and following is the screen when I trigger the invocation. I think this isn't what I should be getting.

Instead I should be getting the one providing four ways of sharing i.e. BBM, BBM Group, Bluetooth and Tag. Previously I was achieving it when I was trying with uri: "file:///share.txt". I'm attaching its screenshot as well.

What I need is data..and not uri ! that's clear...but something is still going wrong, I'll be very thankful if you could help out.

Hi

Try the following

in C++

QByteArray MyClass::getByteArray(QString str)
{
return str.toAscii();
}

and set the context for QML

QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

qml->setContextProperty("app", this);  /// this must point to MyClass

in QML

data: app.getByteArray("your_string")

Hi,
I converted my string to ByteArray in QML itself. So ideally it should work now. but still I'm not getting options for sharing (as shown in screenshot2 above.)

I was having same error as you are. Take a look at this sample: https://github.com/blackberry/Cascades-Community-Samples/tree/master/InvokeClient and see how they implemented app.invokeQuery() and app.processQueryReply()

You need to create your own list of matching applications that can allow you to share this text. After you have this code ready: use IN QML:
Invocation {
id: invoke
query: InvokeQuery {
mimeType: "text/txt"
data: "I am staying at Hilton"
}

However, I do not see BBM or BBM Group in the list. How can I get BBM and BBMGroup in the list?

[farahhanif]

mimeType: "text/plain" shows the BBM option

I would like to share a few lines of text including line breaks ("\n"). Is it possible?
