[Moved] ListView inside ComboBox wont populate...PLz help

andresteves

Hi all, im a newbie at Qt/QML and Symbian. Sorry for my english.

I have a situation and i am starting to get desperate without knowing what to do.
I got the QML ComboBox from "Qt Components":https://qt.gitorious.org/qt-components/qt-components/blobs/f97eb3eb5d6e9de3bfca69d291ffc1564aee8a01/ComboBox.qml

My situation is that i want to populate the QML ComboBox with elements from C++ (a QStringList). Next i will present the errors and the code where i am trying to populate the ComboBox. Just a heads up: the ComboBox has a ListView where the items are inserted.

Errors:
@file:///C:/Users/andre.esteves/Launcher-build-simulator/qml/Launcher/styles/default/ComboBoxStyle.qml:108: Unable to assign [undefined] to QString text
file:///C:/Users/andre.esteves/Launcher-build-simulator/qml/Launcher/styles/default/ComboBoxStyle.qml:92: TypeError: Result of expression 'model.get' [undefined] is not a function.@

C++ Code:
@
QStringList appName; //Im filling this in the real code, so no worries
QDeclarativeView view;
QDeclarativeContext *ctxt = view.rootContext();
ctxt->setContextProperty ("apps", appName);
view.setSource(QUrl::fromLocalFile("example.qml");
view.show();
@
view.show() isnt for display the example.qml file? Im trying to move from one QML file to another with this show() function.

Part of the QML Code:
@
Item {
Column {
x: 33
y: 193
width: 251
height: 40
spacing: 10

  ComboBox{
      id: appbox
      model:myModel

      ListView{
          id:myModel
          model:apps
      }
  }

}
}
@

If u need more details, ill be happy to provide.
Thanks for any help,
Estevex

I do not understand why there is a ListView inside the ComboBox.
Are you able to show your QStringList items in ListView alone, or in ComboBox alone?
If not, you may simply copy from the QStringList example:

Part of the QML Code:
@
Item {
..............
ComboBox{
id: appbox
model:myModel

      ListView{
          id:myModel
          model:apps
      }
  }

}
}

Briefly went through ComboBox code. You don't need to have ListView in your code. Its already defined inside ComboBox.

try below code

@Item {
..............
ComboBox{
id: appbox
model:myModel
}
}
}

Hi thx for the hint Vijay. Trying that.

For my other question:
I want to show a different qml file with view.show(). The thing is that i am inside a qml file and want to jump to another qml file. the show() function would do that?

Thanks for the help

Are you coding for Symbian platform?? If so you should try ApplicationWindow, PageStack, and Page. You can easily do what you asked for with those elements.

Im coding for Symbian but on Qt 4.7. Goig to check if i can use those libraries on Qt 4.7 .
