[Solved] QML ComboBox model from C++

skammers

Hey!

I have a list from C++ containing language code, language description and a flag for the corresponding country.
I made the connection to QML, but cant get to set the model right.
I tried different approaches and either I get an empty ComboBox, or I get a ComboBox containing only one alternative, which is "0".

This is the code for the ComboBox:

@
ComboBox{
id: langSelection;
editable: false;
width: caText.width;
model: LanguageList.languageList;

                textRole:{
                    if(LanguageList.langList.langCode !== undefined){
                        LanguageList.langList.langCode;
                    }

                }

Hi,

I'm not sure if this is correct but I use QVariantList with strings for ComboBox. For example:
@
QVariantList MslHelpers::keychainActionTypeList()
{
QVariantList list;
list.clear();

list.append("Unknown Action");
list.append("Save Datas Action");
list.append("Remove Datas By Kyes Action");

return list;

}

and used it like this:
@
ComboBox {
id: keychaninActionBox
width: 200
model: manager.typeManager.keychainActionTypeList()
}

You can look at the examples given in <QtInstallDir>\examples\quick\models about exporting C++ models to QML ?

Also ComboBox has 'model' property. You should be able to set this property by model which is exposed from C++.

Thanks for the replies, but I got it to work, I set it up like this:

@
ComboBox{
id: comboBox;
width: caText.width;
model: languageList.langList;
textRole: "langDescription";
}
