# TableModelColumn QML Type

Represents a column in a model. More...

## Detailed Description

The TableModelColumn class represents columns in TableModel. TableModel supports JavaScript/JSON data where each row is an object, a list of simple key-value pairs where the keys are unordered.

     {
         // Each property is one cell/column.
         checked: false,
         amount: 1,
         fruitType: "Apple",
         fruitName: "Granny Smith",
         fruitPrice: 1.50
     },
     // ...

However, models in Qt are manipulated via row and column indices. Specifying the columns with TableModelColumn allows a mapping between Qt's built-in roles to any property in each row object.

                 ]
             }
             delegate:  TextInput {
                 text: model.display
                 padding: 12
                 selectByMouse: true

                 onAccepted: model.display = text

                 Rectangle {
                     anchors.fill: parent
                     color: "#efefef"
                     z: -1
                 }
             }
         }
     }

TableModelColumn also has basic read-only support for complex rows. For more information, see Supported Row Data Structures.

Note: Most of the above concepts also apply to TreeModel, except in TreeModel each row represents a node of the tree.

## Supported Roles

TableModelColumn supports all of Qt's roles, with the exception of `Qt::InitialSortOrderRole`. Roles can be accessed by as listed below, e.g.

     text: display

     required property string display

Qt::DisplayRole | display
Qt::DecorationRole | decoration
Qt::EditRole | edit
Qt::ToolTipRole | toolTip
Qt::StatusTipRole | statusTip
Qt::WhatsThisRole | whatsThis
Qt::FontRole | font
Qt::TextAlignmentRole | textAlignment
Qt::BackgroundRole | background
Qt::ForegroundRole | foreground
Qt::CheckStateRole | checkState
Qt::AccessibleTextRole | accessibleText
Qt::AccessibleDescriptionRole | accessibleDescription
Qt::SizeHintRole | sizeHintRoleNam
