Detailed Description
QStyleOptionToolButton contains all the information that QStyle functions need to draw QToolButton.
For performance reasons, there are few member functions and the access to the member variables is direct (i.e., using the . or -> operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

Member Type Documentation
enum QStyleOptionToolButton::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 |
|---|---|---|
QStyleOptionToolButton::Type | SO_ToolButton | The type of style option provided (SO_ToolButton 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 QStyleOptionToolButton::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 |
|---|---|---|
QStyleOptionToolButton::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.
See also StyleOptionType.
enum QStyleOptionToolButton::ToolButtonFeature
flags QStyleOptionToolButton::ToolButtonFeatures
Describes the various features that a tool button can have.
| Constant | Value | Description |
|---|---|---|
QStyleOptionToolButton::None | 0x00 | A normal tool button. |
QStyleOptionToolButton::Arrow | 0x01 | The tool button is an arrow. |
QStyleOptionToolButton::Menu | 0x04 | The tool button has a menu. |
QStyleOptionToolButton::PopupDelay | 0x08 | There is a delay to showing the menu. |
QStyleOptionToolButton::HasMenu | 0x10 | The button has a popup menu. |
QStyleOptionToolButton::MenuButtonPopup | Menu | The button should display an arrow to indicate that a menu is present. |
The ToolButtonFeatures type is a typedef for QFlags<ToolButtonFeature>. It stores an OR combination of ToolButtonFeature values.
