Combobox with multiple column

jimcad

I'm trying display Qt Quick Control ComboBox with multiple column such as here http://www.codeproject.com/KB/combobox/MultiColumnCombo/comboOpen.jpg

I have done this in widget based ui

ui->comboBox->setModel(model);
ui->comboBox->setView(myView);

but how this can be done with QML and Qt Quick Controls? Any ideas?

Thanks in advanced!

Hmmm.... Maybe I can use ListView. What is the best way to show it in popup?

Hi,

Create CustomComboBox Inherit QComboBox.
Reimplemented showPopup() method.

void CustomComboBox::showPopup()
 {
  //create/populate QTableWidget
  //set windowflags  
  //calculate position and size
  //and show()   tablewidget   :-)
 }

Hi @jimcad
AFAIK you can try by using ComboBoxStyle. In it there are still some private properties which can be taken advantage of. For eg. __dropDownStyle which can be used to modify the drop down.

model: ListModel {
    id: cbItems
    ListElement { text: "Banana"; color: "Yellow" }
    ListElement { text: "Apple"; color: "Green" }
    ListElement { text: "Coconut"; color: "Brown" }
}

style: ComboBoxStyle {
   ...
   ...
__dropDownStyle: MenuStyle {
    itemDelegate.label: Item {
        height: 40
        Row {
            Rectangle { height: 40; width: 50; Text { anchors.centerIn: parent; text:  cbItems.get(styleData.index).text } }
            Rectangle { height: 40; width: 50; Text { anchors.centerIn: parent; text:  cbItems.get(styleData.index).color } }
        }
    }
}

I doubt that it can provide the same look and feel but I think its worth a try.
