Hello,

I've been struggling with this for some hours now. I followed the "dialogs" example available at github, so I successfully created a SystemPrompt (the dialog that lets the user to enter text, and accept / dismiss it). Strangely enough, in that example there's no use of the user input text. Do you know how can I get that text in my QML? Here you have some sample code I'm using:

My QML:

// Default empty project template
import bb.cascades 1.0
import bb.system 1.0

// creates one page with a label
NavigationPane {
    id: navigationPane
	Page {
	    attachedObjects: [
            SystemPrompt {
	            id: prompt
	            title: qsTr("Enter a text for the label")
	            modality: SystemUiModality.Application
	            inputField.inputMode: SystemUiInputMode.Default
	            inputField.emptyText: "Label text..."
	            confirmButton.label: qsTr("Ok")
	            confirmButton.enabled: true
	            cancelButton.label: qsTr("Cancel")
	            cancelButton.enabled: true
	            onFinished: {
                    if (result == SystemUiResult.ConfirmButtonSelection) {
                        lab1.text = ????? // Here is where I don't know what to do
                    }
	            }
	        }
        ]
	                
	    Container {
	        layout: StackLayout {}
	        
	        Label {
                        id: lab1
		        text: "Label text"
		        objectName: "lab1"
		        textStyle.base: SystemDefaults.TextStyles.TitleText
		        horizontalAlignment: HorizontalAlignment.Center
	        }
	        
	        Button {
	            text: "Update label"
	            horizontalAlignment: HorizontalAlignment.Center
	            topMargin: 150.0
	            onClicked: {
	                //_appUi.editLabel();
	                prompt.show();
	            }
	        }
	    }
	}
}

 Don't forget to add this in your app .cpp or .hpp file:

#include <bb/system/SystemCredentialsPrompt>
#include <bb/system/SystemDialog>
#include <bb/system/SystemPrompt>
#include <bb/system/SystemToast>
#include <bb/system/SystemUiButton>
#include <bb/system/SystemUiError>
#include <bb/system/SystemUiInputField>
#include <bb/system/SystemUiInputMode>
#include <bb/system/SystemUiPosition>
#include <bb/system/SystemUiResult>

 and also don't forget to include these in your app .cpp file (probably not all of them are needed but just in case I'm leaving them here for the moment):

qmlRegisterType<bb::system::SystemUiButton>("bb.system", 1, 0, "SystemUiButton");
	qmlRegisterType<bb::system::SystemUiInputField>("bb.system", 1, 0, "SystemUiInputField");
	qmlRegisterType<bb::system::SystemToast>("bb.system", 1, 0, "SystemToast");
	qmlRegisterType<bb::system::SystemPrompt>("bb.system", 1, 0, "SystemPrompt");
	qmlRegisterType<bb::system::SystemCredentialsPrompt>("bb.system", 1, 0, "SystemCredentialsPrompt");
	qmlRegisterType<bb::system::SystemDialog>("bb.system", 1, 0, "SystemDialog");
	qmlRegisterUncreatableType<bb::system::SystemUiError>("bb.system", 1, 0, "SystemUiError", "");
	qmlRegisterUncreatableType<bb::system::SystemUiResult>("bb.system", 1, 0, "SystemUiResult", "");
	qmlRegisterUncreatableType<bb::system::SystemUiPosition>("bb.system", 1, 0, "SystemUiPosition", "");
	qmlRegisterUncreatableType<bb::system::SystemUiInputMode>("bb.system", 1, 0, "SystemUiInputMode", "");
	qmlRegisterUncreatableType<bb::system::SystemUiModality>("bb.system", 1, 0, "SystemUiModality", "");
	qRegisterMetaType<bb::system::SystemUiResult::Type>("bb::system::SystemUiResult::Type");

Many thanks,

If you scan ever so carefully through the docs, you'll stumble over https://developer.blackberry.com/cascades/reference/bb__system__systemprompt.html#inputfieldtextentr...

So replace your ????? with inputFieldTextEntry() and you'll get the text you need.

Thanks Peter. I went a couple of times through the SystemPrompt documentation, but I didn't realize about this method. I think It's time to rest now... hehe

Peter, what does the documentation say about working in C++? How do you retrieve the text value then?

This should work the same in C++.  I don't generally use C++ so I can't advise further. Have you tried it?  If you did and it's not working, please post specifics (preferably in a new thread since this one is answered, so relatively few people would see your question if you just add it here).

Thanks for the reply. I found my way through. I also don't use C++ regularly, thus I rely on the documentation, which in this case is incomplete, misleading and with errors in the code examples.
