Returns true if this item handles child events (i.e., all events intended for any of its children are instead sent to this item); otherwise, false is returned.
This property is useful for item groups; it allows one item to handle events on behalf of its children, as opposed to its children handling their events individually.
The default is to return false; children handle their own events. The exception for this is if the item is a QGraphicsItemGroup, then it defaults to return true.
Returns the item's affine transformation matrix. This is a subset or the item's full transformation matrix, and might not represent the item's full transformation.
Rotates the current item transformation angle degrees clockwise around its origin. To translate around an arbitrary point (x, y), you need to combine translation and rotation with setTransform().
Example:
// Rotate an item 45 degrees around (0, 0).
item->rotate(45);
// Rotate an item 45 degrees around (x, y).
item->setTransform(QTransform().translate(x, y).rotate(45).translate(-x, -y));
Scales the current item transformation by (sx, sy) around its origin. To scale from an arbitrary point (x, y), you need to combine translation and scaling with setTransform().
Example:
// Scale an item by 3x2 from its origin
item->scale(3, 2);
// Scale an item by 3x2 from (x, y)
item->setTransform(QTransform().translate(x, y).scale(3, 2).translate(-x, -y));
If enabled is true, this item is set to handle all events for all its children (i.e., all events intented for any of its children are instead sent to this item); otherwise, if enabled is false, this item will only handle its own events. The default value is false.
This property is useful for item groups; it allows one item to handle events on behalf of its children, as opposed to its children handling their events individually.
If a child item accepts hover events, its parent will receive hover move events as the cursor passes through the child, but it does not receive hover enter and hover leave events on behalf of its child.
Sets the item's affine transformation matrix. This is a subset or the item's full transformation matrix, and might not represent the item's full transformation.
Translates the current item transformation by (dx, dy).
If all you want is to move an item, you should call moveBy() or setPos() instead; this function changes the item's translation, which is conceptually separate from its position.
