## Detailed Description

The QStyleOptionToolBar class is used to describe the parameters for drawing a toolbar.

The QStyleOptionToolBar class holds the lineWidth and the midLineWidth for drawing the widget. It also stores information about which area the toolbar should be located in, whether it is movable or not, which position the toolbar line should have (positionOfLine), and the toolbar's position within the line (positionWithinLine).

In addition, the class provides a couple of enums: The ToolBarFeature enum is used to describe whether a toolbar is movable or not, and the ToolBarPosition enum is used to describe the position of a toolbar line, as well as the toolbar's position within the line.

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

## Member Type Documentation

### enum QStyleOptionToolBar::ToolBarFeature
flags QStyleOptionToolBar::ToolBarFeatures

This enum is used to describe whether a toolbar is movable or not.

Constant | Value | Description
--- | --- | ---
`QStyleOptionToolBar::None` | `0x0` | The toolbar cannot be moved. The default value.
`QStyleOptionToolBar::Movable` | `0x1` | The toolbar is movable, and a handle will appear when holding the cursor over the toolbar's boundary.

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

See also features and QToolBar::isMovable().

### enum QStyleOptionToolBar::ToolBarPosition

This enum is used to describe the position of a toolbar line, as well as the toolbar's position within the line.

The order of the positions within a line starts at the top of a vertical line, and from the left within a horizontal line. The order of the positions for the lines is always from the the parent widget's boundary edges.

Constant | Value | Description
--- | --- | ---
`QStyleOptionToolBar::Beginning` | `0` | The toolbar is located at the beginning of the line, or the toolbar line is the first of several lines. There can only be one toolbar (and only one line) with this position.
`QStyleOptionToolBar::Middle` | `1` | The toolbar is located in the middle of the line, or the toolbar line is in the middle of several lines. There can several toolbars (and lines) with this position.
`QStyleOptionToolBar::End` | `2` | The toolbar is located at the end of the line, or the toolbar line is the last of several lines. There can only be one toolbar (and only one line) with this position.
`QStyleOptionToolBar::OnlyOne` | `3` | There is only one toolbar or line. This is the default value of the positionOfLine and positionWithinLine variables.

See also positionWithinLine and positionOfLine.
