*
|
|
* TableView
|
|
*
|
|
* This component provides an item-view with resizable
|
|
* header sections.
|
|
*
|
|
* You can style the drawn delegate by overriding the itemDelegate
|
|
* property. The following properties are supported for custom
|
|
* delegates:
|
|
*
|
|
* Note: Currently only row selection is available for this component
|
|
*
|
|
* itemheight - default platform size of item
|
|
* itemwidth - default platform width of item
|
|
* itemselected - if the row is currently selected
|
|
* itemvalue - The text for this item
|
|
* itemforeground - The default text color for an item
|
|
*
|
|
* For example:
|
|
* itemDelegate: Item {
|
|
* Text {
|
|
* anchors.verticalCenter: parent.verticalCenter
|
|
* color: itemForeground
|
|
* elide: Text.ElideRight
|
|
* text: itemValue
|
|
* }
|
|
* }
|
|
*
|
|
* Data for each row is provided through a model:
|
|
*
|
|
* ListModel {
|
|
* ListElement{ column1: "value 1"; column2: "value 2"}
|
|
* ListElement{ column1: "value 3"; column2: "value 4"}
|
|
* }
|
|
*
|
|
* You provide title and size properties on TableColumns
|
|
* by setting the default header property :
|
|
*
|
|
* TableView {
|
|
* TableColumn{ property: "column1" ; caption: "Column 1" ; width:100}
|
|
* TableColumn{ property: "column2" ; caption: "Column 2" ; width:200}
|
|
* model: datamodel
|
|
* }
|
|
*
|
|
* The header sections are attached to values in the datamodel by defining
|
|
* the listmodel property they attach to. Each property in the model, will
|
|
* then be shown in each column section.
|
|
*
|
|
* The view itself does not provide sorting. This has to
|
|
* be done on the model itself. However you can provide sorting
|
|
* on the model and enable sort indicators on headers.
|
|
*
|
|
* sortColumn - The index of the currently selected sort header
|
|
* sortIndicatorVisible - If sort indicators should be enabled
|
|
* sortIndicatorDirection - "up" or "down" depending on state
|
|
*
|
