Detailed Description

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.

class StyleOptionType

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

Constant

Description

QStyleOptionGraphicsItem.StyleOptionType.Type

The type of style option provided ( SO_GraphicsItem 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.

class StyleOptionVersion

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

Constant

Description

QStyleOptionGraphicsItem.StyleOptionVersion.Version

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.

__init__()

Constructs a QStyleOptionGraphicsItem .

__init__(other)
Parameters:

other – QStyleOptionGraphicsItem

Constructs a copy of other.

__init__(version)
Parameters:

version – int

Constructs a copy of other.

static levelOfDetailFromTransform(worldTransform)
Parameters:

worldTransform – QTransform

Return type:

float

Returns the level of detail from the worldTransform.

Its value represents the maximum value of the height and width of a unity rectangle, mapped using the worldTransform of the painter used to draw the item. By default, if no transformations are applied, its value is 1. If zoomed out 1:2, the level of detail will be 0.5, and if zoomed in 2:1, its value is 2.
