Hery my code

hand. QML where I have a Navegationpane, then SegmentedControl and Lisview (myLVNuevo). When I select an item, I take the Id (selectedItem.IdLibro), I create and send another to the qml (bibliapage.qml). His works, in fact.

 NavigationPane {
            id: navpaneBible
            Page {
                Container {
                    horizontalAlignment: HorizontalAlignment.Fill
                    verticalAlignment: VerticalAlignment.Fill

                    leftPadding: 30
                    topPadding: 30
                    rightPadding: 30
                    bottomPadding: 30

                    SegmentedControl {
                        id: sgfavorites
                        accessibility.name:  sgfavorites
                        Option {
                            id: option1
                            text: "Antiguo"
                            selected: true
                        }
                        Option {
                            id: option2
                            text: "Nuevo"
                        }

                        onSelectedOptionChanged: {

                            if (selectedOption == option1) {

                                myLVNuevo.visible = false;                          

                            } else if (selectedOption == option2) {

                                myLVNuevo.visible = true;                        

                            }

                             }
                        }

                    }
                }
                attachedObjects: [

                    GroupDataModel {
                        id: gdmNuevo
                    },
                    DataSource {
                        id: dtNuevo

                        // Load the data from an SQL database, based on a specific query
                        source: "asset:///sql/MyBiblia.db"
                        query: "select IdLibro, NombreLibro, Testamento from Libros Where Testamento = 'Nuevo' order by IdLibro DESC"
                        onDataLoaded: {
                            // After the data is loaded, insert it into the data model
                            gdmNuevo.clear();
                            gdmNuevo.insertList(data);
                        }
                    } // end of DataSource
                ]

                onCreationCompleted: {
                        dtNuevo.load();
                }
            } // end of Page

But then when the page is loaded, is not load or filter by property string idlibro. Becuse the query in the data source is idlibro.

 import bb.cascades 1.4
import bb.data 1.0
import bb.cascades.datamanager 1.2
Page {
property string idlibro;
property alias texto: lblNombre.text;

    titleBar: TitleBar {
        id: titlebar
        title: texto
    }
    Container {
        id: bibliapagina;

        Label {
            id: lblNombre
            accessibility.name: lblNombre

            text: texto //qsTr("Pagina de la biblia") + Retranslate.onLocaleOrLanguageChanged

        }
        ListView {
            accessibility.name: myLVCapitulos
            id: myLVCapitulos
            dataModel: dm //gdmCapitulos
            listItemComponents: [
                ListItemComponent {
                    type: "item"
                    StandardListItem {
                        title: ListItemData.Capitulo
                        description: ListItemData.Versiculo
                        status: ListItemData.IdVersiculo
                    }
                }
            ]
            onTriggered: {
                if (indexPath.length > 1) {

                }
            }

            attachedObjects: [
                GroupDataModel {
                    id: gdmCapitulos

                },
                DataSource {
                    id: dtCapitulos

                    // Load the data from an SQL database, based on a specific query
                    source: "asset:///sql/MyBiblia.db"
                    query: "select ('Capítulo ' || IdCapitulo) as Capitulo, IdVersiculo, Versiculo from CapitulosVers Where IdLibro = " + lblNombre.text + " GROUP BY IdCapitulo ORDER BY IdCapitulo DESC" 
onDataLoaded: {
                        gdmCapitulos.clear();
                        gdmCapitulos.insertList(data);
                    }
                }
            ]

            onCreationCompleted: {
                dtCapitulos.load();

            }

        }
    }
}

HOW CAN I ACHIEVE THIS?

ITS important to say, its fine words is a set a query without params. example (select * from CapitulosVers Where idlibro = 1).

THANKS IN ADVANCE

I did the solution...

in the second .qml, just before closing the page, put this:

 onIdlibroChanged: { dtCapitulos.query = "select ('Capítulo ' || IdCapitulo) as Capitulo, IdCapitulo, IdVersiculo, Versiculo from CapitulosVers Where IdLibro = " + idlibro + " GROUP BY IdCapitulo ORDER BY IdCapitulo DESC" dtCapitulos.load();

 }

 onCreationCompleted: {
                dtCapitulos.load();

            }

    Hey @claregirl7,

    I understand that you are experiencing problems printing envelopes to your HP Officejet 4500 all-in-One Printer G510g. I want to help you solve this issue. As you said, you know how to load envelopes and you just need advice on where to change the pattern of how the envelope is responsible. In order for me to give you the troubleshooting steps specific I have a few questions for you.

    1. what operating system is on your computer?

    What is my OS?

    2. what type of program are you printing envelopes of?

    3. you print the envelope size #10 standard?

    That being said, most people print envelopes in Word so I'll give you the steps on how to correctly print an envelope through this program. Again, these steps should be incorrect do not forget to reply to this message with your operating system and the program you are printing from so I can give you exact measurements.

    How to print envelopes from Word:

    1. Open Word and click Mail Merge to top
    2. Select "Envelopes" in the upper left side
    3. A page of envelopes and labels should now open. Enter your delivery and return address.
    4. Select 'Options' on the lower right.
    5. Under the tab"Options of the envelope 'to ensure that your envelope size is correctly selected.
    6. Select the tab"print"at the top Options Now you must select the method of diet appropriate for your product.
    7. Make sure that you choose the option 'face '.
    8. Also to ensure that "Needles" is enabled.
    9. Press 'OK' and 'print '.

    Also, I'll include loading envelopes paper for your printer for additional advice.

    We do not have the software 10.8 HP for your printer posted on hp.com and yet, once that happens, you can just download and install. You don't need to do it though, in order to get your printer running on your new Mac.  Simply connect your printer, on the sur le meme same wireless network or via a USB cable, add in printing and fax and let the operating system find and install the software from the Apple software update.  You will be able to the printer and scanning will however be of Image Capture.

    Hello world

    I try my app to display the title and favico starting from a given url without showing the content of the Web page itself using the class bb::cascades:WebPage, but after the constructor method and setUrl, apparently not start the loading content and methods title() both icon give anything (or loading())

    Any idea on how to load the webpage using this class?

    Web page * bookmark = new WebPage();

    Bookmark-> setUrl (request.uri ());

    root->findChild ('message')-> setProperty ('text', QString (bookmark-> title()));

    }

    Thanks in advance

    I have use the class Web page, but the documentation, it seems you should subscribe to the loadingChanged signal and wait for the download to complete. The download can begin asynchronously so loading() might return false immediately after the definition of the URL.

  • How to load programs from a CD which does not automatically load

    I am new to windows 7. I want to load a program from a CD. It was easy with the Control Panel Add and deleate one program; or the execution of the order. Now, I don't know how to load a program from a CD which does not automatically load. Help!

    How can I install software on a disk?

    1. Insert the CD/DVD
    2. If the CD is not automatic open start Windows Explorer - click on start, then click computer.
    3. in the Windows Explorer window, open the drive that contains the installation files. For example, if they are on a CD or DVD open that drive or the letter of the disk drive.
    4. in the disk that contains your files, look for either a configuration or installation of the file. Double-click on this file should launch the installation of the program, a game or utility.
