For performance reasons, there are few member functions and the access to the member variables is direct (i.e., using the
-> operator). This 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.
version – int
QStyleOptionToolBox , initializing the members variables to their default values.
This enum is used to hold information about the type of the style option, and is defined for each
The type of style option provided (
SO_ToolBoxfor this class).
The type is used internally by
QStyleOption , its subclasses, and 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
The version is used by
QStyleOption subclasses to implement extensions without breaking compatibility. If you use , you normally do not need to check it.
This enum describes tab positions relative to other tabs.
The tab is the first (i.e., top-most) tab in the toolbox.
The tab is placed in the middle of the toolbox.
The tab is placed at the bottom of the toolbox.
There is only one tab in the toolbox.
This enum describes the position of the selected tab. Some styles need to draw a tab differently depending on whether or not it is adjacent to the selected tab.
The tab is not adjacent to a selected tab (or is the selected tab).
The next tab (typically the tab on the right) is selected.
The previous tab (typically the tab on the left) is selected.
