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 PySide6.QtWidgets.QStyleOptionGraphicsItem#

PySide6.QtWidgets.QStyleOptionGraphicsItem(other)

PySide6.QtWidgets.QStyleOptionGraphicsItem(version)

Parameters:

Constructs a QStyleOptionGraphicsItem .

Constructs a copy of other.

Constructs a copy of other.

PySide6.QtWidgets.QStyleOptionGraphicsItem.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.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.

PySide6.QtWidgets.QStyleOptionGraphicsItem.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.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.

static PySide6.QtWidgets.QStyleOptionGraphicsItem.levelOfDetailFromTransform(worldTransform)#
Parameters:

worldTransform – PySide6.QtGui.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.
