Use Qt. locale to display local data, and use qt. locale to localize

We know that for some applications, we can display different data formats, such as time and money, based on the language selection. In today's routine, we will show you how to use Qt. locale to display data in different formats based on different languages.

In the routine, note the following syntax:

 

 

delegate: Text {                        property string locale: modelData                        height: units.gu(3)                        width: view.width                        text: Qt.locale(modelData).name + " ("+ Qt.locale(modelData).nativeCountryName + "/" + Qt.locale(modelData).nativeLanguageName + ")"                        MouseArea {                            anchors.fill: parent                            onClicked: view.currentIndex = index                        }                    }

We can get the modelData of the current Item by defining a property locale. In this way, we use

 

 

 

 property string locale: view.currentItem.locale

To get the modelData in the current list, and then reference it in other parts of the program!
