List view section from QStringList

Mabrouk

Hi,

i made a list view in qml, which uses for model a QStinrgList like "this example":http://developer.qt.nokia.com/doc/qt-4.8/declarative-modelviews-stringlistmodel.html

and i want to make sections in the view for the first letter of the string item in the list, how can i do that ?

QString provided by the C++ side becomes JavaScript String so use its interface to access string content. For your case it will be just a list of str[0] where str is the string from the model you have passed to QML

Mabrouk

well, i added the following on the previous example and didn't work

@section.criteria: ViewSection.FirstCharacter
section.property: myModel[0]
section.delegate: Rectangle{color: "green"; width: parent.width; height: 20}

obviously it doesn't work, you should use the model item not the model itself. See the example, link to which you have provided, it uses modelData for each created delegate not the myModel

Mabrouk

well, i don't understand what you mean exactly
but i tried to replace myModel with modelData and it got me and error

past the full QML code you have, please

here you are

@import QtQuick 1.0

ListView {
width: 100; height: 100
anchors.fill: parent

 model: myModel

 section.criteria: ViewSection.FirstCharacter
 section.property: medelData[0]
 section.delegate: Rectangle{color: "green"; width: parent.width; height: 20}
 delegate: Rectangle {
     height: 25
     width: 100
     Text { text: modelData }
 }

}@

try this out
@import QtQuick 1.0

ListView {
width: 100; height: 100
anchors.fill: parent
model: myModel

 section.criteria: ViewSection.FirstCharacter
 section.property: "modelData"
 section.delegate: Rectangle{color: "green"; width: parent.width; height: 20}
 delegate: Rectangle {
     height: 25
     width: 100
     Text { text: modelData }
 }

}@
