- class spinetoolbox.spine_db_editor.graphics_items.EntityItem(spine_db_editor, x, y, extent, db_map_ids, offset=None)[source]
Bases:
PySide6.QtWidgets.QGraphicsRectItem
- Parameters:
spine_db_editor (SpineDBEditor) – ‘owner’
x (float) – x-coordinate of central point
y (float) – y-coordinate of central point
extent (int) – Preferred extent
db_map_ids (tuple) – tuple of (db_map, id) tuples
- has_unique_key()[source]
Returns whether or not the item still has a single key in all the databases it represents.
- Returns:
bool
- default_parameter_data()[source]
Return data to put as default in a parameter table when this item is selected.
- shape()[source]
Returns a shape containing the entire bounding rect, to work better with icon transparency.
- apply_rotation(angle, center)[source]
Applies rotation.
- Parameters:
angle (float) – The angle in degrees.
center (QPointF) – Rotates around this point.
- mouseMoveEvent(event)[source]
Moves the item and all connected arcs.
- Parameters:
event (QGraphicsSceneMouseEvent)
- itemChange(change, value)[source]
Keeps track of item’s movements on the scene. Rotates svg item if the relationship is 2D. This makes it possible to define e.g. an arow icon for relationships that express direction.
- Parameters:
change (GraphicsItemChange) – a flag signalling the type of the change
value – a value related to the change
- Returns:
the same value given as input
- setVisible(on)[source]
Sets visibility status for this item and all arc items.
- Parameters:
on (bool)
- contextMenuEvent(e)[source]
Shows context menu.
- Parameters:
e (QGraphicsSceneMouseEvent) – Mouse event
Populates the ‘Expand’ or ‘Collapse’ menu.
- Parameters:
menu (QMenu)
Populates the ‘Add relationships’ menu.
- Parameters:
menu (QMenu)
- class spinetoolbox.spine_db_editor.graphics_items.ArcItem(ent_item, el_item, width)[source]
Bases:
PySide6.QtWidgets.QGraphicsPathItem
Connects two EntityItems.
- Parameters:
ent_item (spinetoolbox.widgets.graph_view_graphics_items.EntityItem) – entity item
el_item (spinetoolbox.widgets.graph_view_graphics_items.EntityItem) – element item
width (float) – Preferred line width
- class spinetoolbox.spine_db_editor.graphics_items.CrossHairsItem(*args, **kwargs)[source]
Bases:
