## Detailed Description

The QStyleOptionQ3ListViewItem class is used to describe an item drawn in a Q3ListView.

This class is used for drawing the compatibility Q3ListView's items. It is not recommended for new classes.

QStyleOptionQ3ListViewItem contains all the information that QStyle functions need to draw the Q3ListView items.

For performance reasons, the access to the member variables is direct (i.e., using the `.` or `->` operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

For an example demonstrating how style options can be used, see the Styles example.

See also QStyleOption, QStyleOptionQ3ListView, and Q3ListViewItem.

## Member Type Documentation

### enum QStyleOptionQ3ListViewItem::Q3ListViewItemFeature
flags QStyleOptionQ3ListViewItem::Q3ListViewItemFeatures

This enum describes the features a list view item can have.

Constant | Value | Description
--- | --- | ---
`QStyleOptionQ3ListViewItem::None` | `0x00` | A standard item.
`QStyleOptionQ3ListViewItem::Expandable` | `0x01` | The item has children that can be shown.
`QStyleOptionQ3ListViewItem::MultiLine` | `0x02` | The item is more than one line tall.
`QStyleOptionQ3ListViewItem::Visible` | `0x04` | The item is visible.
`QStyleOptionQ3ListViewItem::ParentControl` | `0x08` | The item's parent is a type of item control (Q3CheckListItem::Controller).

The Q3ListViewItemFeatures type is a typedef for QFlags<Q3ListViewItemFeature>. It stores an OR combination of Q3ListViewItemFeature values.

See also features, Q3ListViewItem::isVisible(), Q3ListViewItem::multiLinesEnabled(), and Q3ListViewItem::isExpandable().

### enum QStyleOptionQ3ListViewItem::StyleOptionType

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption subclass.

Constant | Value | Description
--- | --- | ---
`QStyleOptionQ3ListViewItem::Type` | `SO_Q3ListViewItem` | The type of style option provided (SO_Q3ListViewItem for this class).

The type is used internally by QStyleOption, its subclasses, and qstyleoption_cast() to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles.

See also StyleOptionVersion.

### enum QStyleOptionQ3ListViewItem::StyleOptionVersion

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.

Constant | Value | Description
--- | --- | ---
`QStyleOptionQ3ListViewItem::Version` | `1` | 1

The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally don't need to check it.

See also StyleOptionType.
