## Constructor & Destructor Documentation

## ◆ UMLWidget() [1/2]

UMLWidget::UMLWidget | ( | UMLScene * | scene,
|  | WidgetType | type = `wt_UMLWidget`,
|  | UMLObject * | o = `nullptr`
| ) |  |

explicit

Creates a UMLWidget object.

Parameters

  scene | The view to be displayed on.
  type | The WidgetType to construct. This must be set to the appropriate value by the constructors of inheriting classes.

explicit

Creates a UMLWidget object.

Parameters

  scene | The view to be displayed on.
  type | The WidgetType to construct. This must be set to the appropriate value by the constructors of inheriting classes.
  id | The id of the widget. The default value (id_None) will prompt generation of a new ID.

  showProperties | whether to show properties of the widget

## ◆ adjustAssocs()

void UMLWidget::adjustAssocs | ( | qreal | dx,
|  | qreal | dy
| ) |  |

virtual

Adjusts associations with the given co-ordinates

Parameters

  dx | The amount by which the widget moved in X direction.
  dy | The amount by which the widget moved in Y direction.

Todo:
  avoid trigger of this event during load

Reimplemented in ComponentWidget.

## ◆ adjustUnselectedAssocs()

void UMLWidget::adjustUnselectedAssocs | ( | qreal | dx,
|  | qreal | dy
| ) |  |

virtual

Adjusts all unselected associations with the given co-ordinates

Parameters

  dx | The amount by which the widget moved in X direction.
  dy | The amount by which the widget moved in Y direction.

Reimplemented in ComponentWidget.

## ◆ associationWidgetList()

AssociationWidgetList & UMLWidget::associationWidgetList | ( |  | ) | const

Returns the list of associations connected to this widget.

## ◆ calculateSize()

QSizeF UMLWidget::calculateSize | ( | bool | withExtensions = `true` | ) | const

virtual

calculate content related size of widget.

Returns
  calculated widget size

Reimplemented in ClassifierWidget, EntityWidget, and NoteWidget.

## ◆ cleanup()

void UMLWidget::cleanup | ( |  | ) |

virtual

Used to cleanup any other widget it may need to delete. Used by child classes. This should be called before deleting a widget of a diagram.

Reimplemented in CombinedFragmentWidget, MessageWidget, and ObjectWidget.

## ◆ clipSize()

void UMLWidget::clipSize | ( |  | ) |

clip the size of this widget against the minimal and maximal limits.

## ◆ constrain()

void UMLWidget::constrain | ( | qreal & | width,
|  | qreal & | height
| ) |  |

protected virtual

Apply possible constraints to the given candidate width and height. The default implementation limits input values to the bounds returned by minimumSize()/maximumSize().

Parameters

  width | input value, may be modified by the constraint
  height | input value, may be modified by the constraint

Reimplemented in ActivityWidget, and ForkJoinWidget.

## ◆ constrainMovementForAllWidgets()

void UMLWidget::constrainMovementForAllWidgets | ( | qreal & | diffX,
|  | qreal & | diffY
| ) |  |

protected virtual

Modifies the value of the diffX and diffY variables used to move the widgets.

It can be overridden to constrain movement of all the selected widgets only in one axis even when the user isn't constraining the movement with shift or control buttons, for example. The difference with moveWidgetBy is that the diff positions used here are applied to all the selected widgets instead of only to m_widget, and that moveWidgetBy, in fact, moves the widget, and here simply the diff positions are modified.

Default behaviour is do nothing.

See also
  moveWidgetBy

Parameters

  diffX | The difference between current X position and new X position.
  diffY | The difference between current Y position and new Y position.

Reimplemented in FloatingTextWidget, MessageWidget, and ObjectWidget.

## ◆ contextMenuEvent()

void UMLWidget::contextMenuEvent | ( | QGraphicsSceneContextMenuEvent * | event | ) |

protected virtual

Event handler for context menu events.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget.

## ◆ deselect()

void UMLWidget::deselect | ( | QGraphicsSceneMouseEvent * | me | ) |

protected

Deselects the widget and removes it from the list of selected widgets.

Parameters

  me | The QGraphicsSceneMouseEvent which made the selection.

## ◆ fixedAspectRatio()

bool UMLWidget::fixedAspectRatio | ( |  | ) | const

inline

## ◆ forceUpdateFontMetrics() [1/2]

void UMLWidget::forceUpdateFontMetrics | ( | QFont & | font,
|  | QPainter * | painter
| ) |  |

Note
  For performance Reasons, only FontMetrics for already used font types are updated. Not yet used font types will not get a font metric and will get the same font metric as if painter was zero. This behaviour is acceptable, because diagrams will always be shown on Display first before a special painter like a printer device is used.

## ◆ forceUpdateFontMetrics() [2/2]

void UMLWidget::forceUpdateFontMetrics | ( | QPainter * | painter | ) |

Updates font metrics for widgets current m_font

## ◆ getFontMetrics()

QFontMetrics & UMLWidget::getFontMetrics | ( | UMLWidget::FontType | fontType | ) | const

Returns
  The QGraphicsObject position.

Reimplemented in PinPortBase.

## ◆ getStartMove()

bool UMLWidget::getStartMove | ( |  | ) | const

inline

Returns whether we triggered the update of position movement. If so, you probably don't want to move it.

Returns
  The moving state.

Todo:
  Add support to load older version.

Reimplemented from WidgetBase.

Reimplemented in ActivityWidget, ClassifierWidget, CombinedFragmentWidget, DatatypeWidget, EntityWidget, EnumWidget, FloatingDashLineWidget, FloatingTextWidget, ForkJoinWidget, MessageWidget, NoteWidget, ObjectNodeWidget, ObjectWidget, PinPortBase, PreconditionWidget, RegionWidget, SignalWidget, and StateWidget.

Reimplemented in ActivityWidget, ActorWidget, ArtifactWidget, CategoryWidget, ClassifierWidget, CombinedFragmentWidget, ComponentWidget, DatatypeWidget, EntityWidget, EnumWidget, FloatingTextWidget, ForkJoinWidget, MessageWidget, NodeWidget, NoteWidget, ObjectNodeWidget, ObjectWidget, PackageWidget, PreconditionWidget, RegionWidget, SignalWidget, StateWidget, and UseCaseWidget.

## ◆ mouseDoubleClickEvent()

void UMLWidget::mouseDoubleClickEvent | ( | QGraphicsSceneMouseEvent * | event | ) |

protected virtual

Event handler for mouse double click events.

Parameters

  event | the QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in ClassifierWidget, NoteWidget, and StateWidget.

## ◆ mouseMoveEvent()

void UMLWidget::mouseMoveEvent | ( | QGraphicsSceneMouseEvent * | event | ) |

protected virtual

Handles a mouse move event. It resizes or moves the widget, depending on where the cursor is pressed on the widget. Go on reading for more info about this.

If resizing, the widget is resized using UMLWidget::resizeWidget (where specific widget resize constraint can be applied), and then the associations are adjusted. The resizing can be constrained also to a specific axis using control and shift buttons. If one or another is pressed, it's constrained to X axis. If both are pressed, it's constrained to Y axis.

If not resizing, the widget is being moved. If the move is being started, the selection bounds are set (which includes updating the list of selected widgets). The difference between the previous position of the selection and the new one is calculated (taking in account the selection bounds so widgets don't go beyond the scene limits). Then, it's constrained to X or Y axis depending on shift and control buttons. A further constraint is made using constrainMovementForAllWidgets (for example, if the widget that receives the event can only be moved in Y axis, with this method the movement of all the widgets in the selection can be constrained to be moved only in Y axis). Then, all the selected widgets are moved using moveWidgetBy (where specific widget movement constraint can be applied) and, if a certain amount of time passed from the last move event, the associations are also updated (they're not updated always to be easy on the CPU). Finally, the scene is resized, and selection bounds updated.

Parameters

  event | The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget, ObjectWidget, and SignalWidget.

## ◆ mousePressEvent()

void UMLWidget::mousePressEvent | ( | QGraphicsSceneMouseEvent * | event | ) |

protected virtual

Handles a mouse press event. It'll select the widget (or mark it to be deselected) and prepare it to be moved or resized. Go on reading for more info about this.

Widget values and message bar status are saved.

If shift or control buttons are pressed, we're in move area no matter where the button was pressed in the widget. Moreover, if the widget wasn't already selected, it's added to the selection. If already selected, it's marked to be deselected when releasing the button (provided it isn't moved). Also, if the widget is already selected with other widgets but shift nor control buttons are pressed, we're in move area. If finally we don't move the widget, it's selected and the other widgets deselected when releasing the left button.

If shift nor control buttons are pressed, we're facing a single selection. Depending on the position of the cursor, we're in move or in resize area. If the widget wasn't selected (both when there are no widgets selected, or when there're other widgets selected but not the one receiving the press event) it's selected and the others deselected, if any. If already selected, it's marked to be deselected when releasing the button (provided it wasn't moved or resized).

Parameters

  event | The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget, and ObjectWidget.

## ◆ mouseReleaseEvent()

void UMLWidget::mouseReleaseEvent | ( | QGraphicsSceneMouseEvent * | event | ) |

protected virtual

Handles a mouse release event. It selects or deselects the widget and cancels or confirms the move or resize. Go on reading for more info about this. No matter which tool is selected, Z position of widget is updated.

Middle button release resets the selection. Left button release, if it wasn't moved nor resized, selects the widget and deselect the others if it wasn't selected and there were other widgets selected. If the widget was marked to be deselected, deselects it. If it was moved or resized, the document is set to modified if position or size changed. Also, if moved, all the associations are adjusted because the timer could have prevented the adjustment in the last move event before the release. If mouse was pressed in resize area, cursor is set again to normal cursor Right button release if right button was pressed shows the pop up menu for the widget. If left button was pressed, it cancels the move or resize with a mouse move event at the same position than the cursor was when pressed. Another left button release is also sent.

Parameters

  event | The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget.

## ◆ moveByLocal()

void UMLWidget::moveByLocal | ( | qreal | dx,

## ◆ moveEvent()

void UMLWidget::moveEvent | ( | QGraphicsSceneMouseEvent * | me | ) |

protected virtual

Parameters

  me | The move event.

Reimplemented in ObjectWidget.

## ◆ moveWidgetBy()

void UMLWidget::moveWidgetBy | ( | qreal | diffX,
|  | qreal | diffY
| ) |  |

protected virtual

Moves the widget to a new position using the difference between the current position and the new position. This method doesn't adjust associations. It only moves the widget.

It can be overridden to constrain movement only in one axis even when the user isn't constraining the movement with shift or control buttons, for example. The movement policy set here is applied whenever the widget is moved, being it moving it explicitly, or as a part of a selection but not receiving directly the mouse events.

Default behaviour is move the widget to the new position using the diffs.
