## Detailed Description

A graphical version of a UML State.

This class is the graphical version of a UML State.

A StateWidget is created by a UMLView. A StateWidget belongs to only one UMLView instance. When the UMLView instance that this class belongs to is destroyed, it will be automatically deleted.

The StateWidget class inherits from the UMLWidget class which adds most of the functionality to this class.

## Constructor & Destructor Documentation

## ◆ StateWidget()

StateWidget::StateWidget | ( | UMLScene * | scene,
|  | StateType | stateType = `Normal`,
|  | Uml::ID::Type | id = `Uml::ID::None`
| ) |  |
| explicit

Creates a State widget.

Parameters

  scene | The parent of the widget.
  stateType | The type of state.
  id | The ID to assign (-1 will prompt a new ID.)

## ◆ ~StateWidget()

StateWidget::~StateWidget | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

## ◆ activities()

QStringList StateWidget::activities | ( |  | ) | const

Returns the list of activities.

## ◆ addActivity()

bool StateWidget::addActivity | ( | const QString & | activity | ) |

Adds an activity to this widget.

Returns
  true on success

## ◆ contextMenuEvent()

void StateWidget::contextMenuEvent | ( | QGraphicsSceneContextMenuEvent * | event | ) |
| protectedvirtual

Event handler for context menu events.

Reimplemented from UMLWidget.

## ◆ drawVertical()

bool StateWidget::drawVertical | ( |  | ) | const

Get whether to draw a fork or join vertically.

## ◆ loadFromXMI1()

bool StateWidget::loadFromXMI1 | ( | QDomElement & | qElement | ) |
| virtual

Loads a "statewidget" XMI element.

Reimplemented from UMLWidget.

## ◆ maximumSize()

QSizeF StateWidget::maximumSize | ( |  | ) |
| protectedvirtual

Overrides method from UMLWidget

Reimplemented from UMLWidget.

## ◆ minimumSize()

QSizeF StateWidget::minimumSize | ( |  | ) | const
| protectedvirtual

Overrides method from UMLWidget

Reimplemented from UMLWidget.

## ◆ mouseDoubleClickEvent()

void StateWidget::mouseDoubleClickEvent | ( | QGraphicsSceneMouseEvent * | event | ) |
| protectedvirtual

Event handler for mouse double click events.

Parameters

  event | the QGraphicsSceneMouseEvent event.

Reimplemented from UMLWidget.

## ◆ mouseMoveEvent()

void StateWidget::mouseMoveEvent | ( | QGraphicsSceneMouseEvent * | event | ) |
| protectedvirtual

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 UMLWidget.

## ◆ mousePressEvent()

void StateWidget::mousePressEvent | ( | QGraphicsSceneMouseEvent * | event | ) |
| protectedvirtual

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 UMLWidget.

## ◆ mouseReleaseEvent()

void StateWidget::mouseReleaseEvent | ( | QGraphicsSceneMouseEvent * | event | ) |
| protectedvirtual

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 UMLWidget.

## ◆ paint()

void StateWidget::paint | ( | QPainter * | painter,
|  | const QStyleOptionGraphicsItem * | option,
|  | QWidget * | widget = `0`
| ) |  |
| virtual
