The QStyleOptionMenuItem class is used to describe the parameter necessary for drawing a menu item. QStyleOptionMenuItem contains all the information that QStyle functions need to draw the menu items from QMenu. It is also used for drawing other menu-related widgets.
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.
This enum is used to indicate whether or not a check mark should be drawn for the item, or even if it should be drawn at all.
Constant | Value | Description |
---|---|---|
QStyleOptionMenuItem::NotCheckable | 0 | The item is not checkable. |
QStyleOptionMenuItem::Exclusive | 1 | The item is an exclusive check item (like a radio button). |
QStyleOptionMenuItem::NonExclusive | 2 | The item is a non-exclusive check item (like a check box). |
This enum indicates the type of menu item that the structure describes.
Constant | Value | Description |
---|---|---|
QStyleOptionMenuItem::Normal | 0 | A normal menu item. |
QStyleOptionMenuItem::DefaultItem | 1 | A menu item that is the default action as specified with QMenu::defaultAction(). |
QStyleOptionMenuItem::Separator | 2 | A menu separator. |
QStyleOptionMenuItem::SubMenu | 3 | Indicates the menu item points to a sub-menu. |
QStyleOptionMenuItem::Scroller | 4 | A popup menu scroller (currently only used on Mac OS X). |
QStyleOptionMenuItem::TearOff | 5 | A tear-off handle for the menu. |
QStyleOptionMenuItem::Margin | 6 | The margin of the menu. |
QStyleOptionMenuItem::EmptyArea | 7 | The empty area of the menu. |
This enum is used to hold information about the type of the style option, and is defined for each QStyleOption subclass.
Constant | Value | Description |
---|---|---|
QStyleOptionMenuItem::Type | SO_MenuItem | The type of style option provided (SO_MenuItem 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.
This enum is used to hold information about the version of the style option, and is defined for each QStyleOption subclass.
Constant | Value | Description |
---|---|---|
QStyleOptionMenuItem::Version | 1 | 1 |
The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally do not need to check it.
QStyleOptionMenuItem::QStyleOptionMenuItem | ( | ) |
Constructs an empty QStyleOptionMenuItem.
|
inline |
Copy constructs a new QStyleOptionMenuItem from other.
|
default |
Copy assigns from other and returns a reference to this object.
