Detailed Description¶
QGraphicsScene
provides certain parameters to help control how the scale should be applied.
The origin is the point that the item is scaled from (i.e., it stays fixed relative to the parent as the rest of the item grows). By default the origin is QPointF
(0, 0).
The parameters xScale
, yScale
, and zScale
describe the scale factors to apply in horizontal, vertical, and depth directions. They can take on any value, including 0 (to collapse the item to a point) or negative value. A negative xScale
value will mirror the item horizontally. A negative yScale
value will flip the item vertically. A negative zScale
will flip the item end for end.

- class PySide6.QtWidgets.QGraphicsScale([parent=None])¶
- Parameters
parent –
PySide6.QtCore.QObject
Constructs an empty QGraphicsScale
object with the given parent
.
- PySide6.QtWidgets.QGraphicsScale.origin()¶
- Return type
This property holds the origin of the scale in 3D space..
All scaling will be done relative to this point (i.e., this point will stay fixed, relative to the parent, when the item is scaled).
- PySide6.QtWidgets.QGraphicsScale.originChanged()¶
- PySide6.QtWidgets.QGraphicsScale.scaleChanged()¶
- PySide6.QtWidgets.QGraphicsScale.setOrigin(point)¶
- Parameters
point –
PySide6.QtGui.QVector3D
This property holds the origin of the scale in 3D space..
All scaling will be done relative to this point (i.e., this point will stay fixed, relative to the parent, when the item is scaled).
- PySide6.QtWidgets.QGraphicsScale.setXScale(arg__1)¶
- Parameters
arg__1 – float
This property holds the horizontal scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be mirrored horizontally around its origin.
- PySide6.QtWidgets.QGraphicsScale.setYScale(arg__1)¶
- Parameters
arg__1 – float
This property holds the vertical scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be flipped vertically around its origin.
- PySide6.QtWidgets.QGraphicsScale.setZScale(arg__1)¶
- Parameters
arg__1 – float
This property holds the depth scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be flipped end for end around its origin.
- PySide6.QtWidgets.QGraphicsScale.xScale()¶
- Return type
float
This property holds the horizontal scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be mirrored horizontally around its origin.
- PySide6.QtWidgets.QGraphicsScale.xScaleChanged()¶
- PySide6.QtWidgets.QGraphicsScale.yScale()¶
- Return type
float
This property holds the vertical scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be flipped vertically around its origin.
- PySide6.QtWidgets.QGraphicsScale.yScaleChanged()¶
- PySide6.QtWidgets.QGraphicsScale.zScale()¶
- Return type
float
This property holds the depth scale factor..
The scale factor can be any real number; the default value is 1.0. If you set the factor to 0.0, the item will be collapsed to a single point. If you provide a negative value, the item will be flipped end for end around its origin.
