Property Documentation

alternatingRowColors : bool

This property holds whether to draw the background using alternating colors

If this property is true, the item background will be drawn using QPalette::Base and QPalette::AlternateBase; otherwise the background will be drawn using the QPalette::Base color.

By default, this property is false.

Access functions:

autoScroll : bool

This property holds whether autoscrolling in drag move events is enabled

If this property is set to true (the default), the QAbstractItemView automatically scrolls the contents of the view if the user drags within 16 pixels of the viewport edge. If the current item changes, then the view will scroll automatically to ensure that the current item is fully visible.

This property only works if the viewport accepts drops. Autoscroll is switched off by setting this property to false.

Access functions:

autoScrollMargin : int

This property holds the size of the area when auto scrolling is triggered

This property controls the size of the area at the edge of the viewport that triggers autoscrolling. The default value is 16 pixels.

This property was introduced in Qt 4.4.

Access functions:

defaultDropAction : Qt::DropAction

This property holds the drop action that will be used by default in QAbstractItemView::drag()

If the property is not set, the drop action is CopyAction when the supported actions support CopyAction.

This property was introduced in Qt 4.6.

Access functions:

See also showDropIndicator and dragDropOverwriteMode.

dragDropMode : DragDropMode

This property holds the drag and drop event the view will act upon

This property was introduced in Qt 4.2.

Access functions:

See also showDropIndicator and dragDropOverwriteMode.

dragDropOverwriteMode : bool

This property holds the view's drag and drop behavior

If its value is true, the selected data will overwrite the existing item data when dropped, while moving the data will clear the item. If its value is false, the selected data will be inserted as a new item when the data is dropped. When the data is moved, the item is removed as well.

The default value is false, as in the QListView and QTreeView subclasses. In the QTableView subclass, on the other hand, the property has been set to true.

Note: This is not intended to prevent overwriting of items. The model's implementation of flags() should do that by not returning Qt::ItemIsDropEnabled.

This property was introduced in Qt 4.2.

Access functions:

See also dragDropMode.

dragEnabled : bool

This property holds whether the view supports dragging of its own items

Access functions:

See also showDropIndicator, DragDropMode, dragDropOverwriteMode, and acceptDrops.

editTriggers : EditTriggers

This property holds which actions will initiate item editing

This property is a selection of flags defined by EditTrigger, combined using the OR operator. The view will only initiate the editing of an item if the action performed is set in this property.

Access functions:

horizontalScrollMode : ScrollMode

how the view scrolls its contents in the horizontal direction

This property controls how the view scroll its contents horizontally. Scrolling can be done either per pixel or per item. Its default value comes from the style via the QStyle::SH_ItemView_ScrollMode style hint.

This property was introduced in Qt 4.2.

Access functions:

iconSize : QSize

This property holds the size of items' icons

Setting this property when the view is visible will cause the items to be laid out again.

Access functions:

Notifier signal:

selectionBehavior : SelectionBehavior

This property holds which selection behavior the view uses

This property holds whether selections are done in terms of single items, rows or columns.

Access functions:

See also SelectionMode and SelectionBehavior.

selectionMode : SelectionMode

This property holds which selection mode the view operates in

This property controls whether the user can select one or many items and, in many-item selections, whether the selection must be a continuous range of items.

Access functions:

See also SelectionMode and SelectionBehavior.

showDropIndicator : bool

This property holds whether the drop indicator is shown when dragging items and dropping.

Access functions:

See also dragEnabled, DragDropMode, dragDropOverwriteMode, and acceptDrops.

tabKeyNavigation : bool

This property holds whether item navigation with tab and backtab is enabled.

Access functions:

textElideMode : Qt::TextElideMode

This property holds the position of the "..." in elided text.

The default value for all item views is Qt::ElideRight.

Access functions:

verticalScrollMode : ScrollMode

how the view scrolls its contents in the vertical direction

This property controls how the view scroll its contents vertically. Scrolling can be done either per pixel or per item. Its default value comes from the style via the QStyle::SH_ItemView_ScrollMode style hint.

This property was introduced in Qt 4.2.
