## Detailed Description

Sequence tool to create components linked with one object in sequence diagram like precondition. With sequence tool, one objects is selected clicking with left button on it

## Constructor & Destructor Documentation

## ◆ ToolBarStateOneWidget()

ToolBarStateOneWidget::ToolBarStateOneWidget | ( | UMLScene * | umlScene | ) |
| explicit

Creates a new ToolBarStateOneWidget.

Parameters

  umlScene | The UMLScene to use.

## ◆ ~ToolBarStateOneWidget()

ToolBarStateOneWidget::~ToolBarStateOneWidget | ( |  | ) |
| virtual

Destroys this ToolBarStateOneWidget.

## Member Function Documentation

## ◆ cleanBeforeChange()

void ToolBarStateOneWidget::cleanBeforeChange | ( |  | ) |
| virtual

Called when the current tool is changed to use another tool. Executes base method and cleans the message.

Reimplemented from ToolBarState.

## ◆ init()

void ToolBarStateOneWidget::init | ( |  | ) |
| privatevirtual

Goes back to the initial state.

Reimplemented from ToolBarState.

## ◆ mouseMove()

void ToolBarStateOneWidget::mouseMove | ( | QGraphicsSceneMouseEvent * | ome | ) |
| virtual

Called when a mouse event happened. It executes the base method and then updates the position of the message line, if any.

Reimplemented from ToolBarState.

## ◆ mouseReleaseEmpty()

void ToolBarStateOneWidget::mouseReleaseEmpty | ( |  | ) |
| protectedvirtual

Called when the release event happened on an empty space. Cleans the message. Empty spaces are not only actual empty spaces, but also associations.

Reimplemented from ToolBarState.

## ◆ mouseReleaseWidget()

void ToolBarStateOneWidget::mouseReleaseWidget | ( |  | ) |
| protectedvirtual

Called when the release event happened on a widget. If the button pressed isn't left button or the widget isn't an object widget, the message is cleaned. If the release event didn't happen on the line of an object and the first object wasn't selected, nothing is done. If the first object was already selected, a creation message is made. If the event happened on the line of an object, the first object or the second are set, depending on whether the first object was already set or not.

Reimplemented from ToolBarState.

## ◆ setCurrentElement()

void ToolBarStateOneWidget::setCurrentElement | ( |  | ) |
| protectedvirtual

Selects only widgets, but no associations. Overrides base class method. If the press event happened on the line of an object, the object is set as current widget. If the press event happened on a widget, the widget is set as current widget.

Reimplemented from ToolBarState.

## ◆ setWidget()

void ToolBarStateOneWidget::setWidget | ( | UMLWidget * | firstObject | ) |
| protected

Sets the first object of the message using the specified object. The temporary visual message is created and mouse tracking enabled, so mouse events will be delivered.

Parameters

  firstObject | The first object of the message.

## ◆ slotWidgetRemoved

void ToolBarStateOneWidget::slotWidgetRemoved | ( | UMLWidget * | widget | ) |
| virtualslot

A widget was removed from the UMLView. If the widget removed was the current widget, the current widget is set to 0. Also, if it was the first object, the message is cleaned.

## ◆ widgetType()

WidgetBase::WidgetType ToolBarStateOneWidget::widgetType | ( |  | ) |
| protected

Returns the widget type of this tool.

Returns
  The widget type of this tool.

## Member Data Documentation

## ◆ m_firstObject

UMLWidget* ToolBarStateOneWidget::m_firstObject
| protected

The first object in the message.

## ◆ m_isObjectWidgetLine

bool ToolBarStateOneWidget::m_isObjectWidgetLine
| protected

If there is a current widget, it is true if the press event happened on the line of an object, or false if it happened on a normal UMLWidget.
