## Detailed Description

Displays a line of text or an operation.

This is a multipurpose class. In its simplest form it will display a line of text. It can also be setup to be the text for an operation with regard to the MessageWidget on the sequence diagram. It is also used for the text required for an association.

The differences between all these different uses will be the popup menu that is associated with it.

## Constructor & Destructor Documentation

## ◆ FloatingTextWidget()

FloatingTextWidget::FloatingTextWidget | ( | UMLScene * | scene,
|  | Uml::TextRole::Enum | role = Uml::TextRole::Floating,
|  | const QString & | text = QString(),
|  | Uml::ID::Type | id = Uml::ID::None )
| explicit

Constructs a FloatingTextWidget instance.

Parameters

  scene | The parent of this FloatingTextWidget.
  role | The role this FloatingTextWidget will take up.
  text | The main text to display.
  id | The ID to assign (-1 will prompt a new ID.)

## ◆ ~FloatingTextWidget()

FloatingTextWidget::~FloatingTextWidget | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

## ◆ activate()

bool FloatingTextWidget::activate | ( | IDChangeLog * | ChangeLog = 0 | ) |
| virtual

Activate the FloatingTextWidget after the saved data has been loaded

Parameters

  ChangeLog | Pointer to the IDChangeLog.

Returns
  true for success

Reimplemented from UMLWidget.

## ◆ changeName()

void FloatingTextWidget::changeName | ( | const QString & | newText | ) |

Changes the text of linked widget.

Parameters

  newText | the new text

## ◆ constrainMovementForAllWidgets()

void FloatingTextWidget::constrainMovementForAllWidgets | ( | qreal & | diffX,
|  | qreal & | diffY )
| protectedvirtual

Overridden from UMLWidget. Modifies the value of the diffX and diffY variables used to move the widgets. The values are constrained using constrainPosition.

See also
  constrainPosition

Parameters

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

Reimplemented from UMLWidget.

## ◆ constrainPosition()

QPointF FloatingTextWidget::constrainPosition | ( | qreal | diffX,
|  | qreal | diffY )
| private

Returns a constrained position for the widget after applying the position difference. If no link widget exists, the position returned is the current widget position with the difference applied. If there's a link, the position to be returned is constrained using constrainTextPos method from the LinkWidget, if any.

Parameters

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

Returns
  A QPointF with the constrained new position.

## ◆ displayText()

QString FloatingTextWidget::displayText | ( |  | ) | const

Use to get the total text (prepended + main body + appended) currently displayed by the widget.

Returns
  The text currently being displayed by the widget.

## ◆ handleRename()

bool FloatingTextWidget::handleRename | ( |  | ) |

Handle the ListPopupMenu::mt_Rename case of the slotMenuSelection. Given an own method because it requires rather lengthy code.

## ◆ isEmpty()

bool FloatingTextWidget::isEmpty | ( |  | ) |

Return state if no pre, post and main text is empty

Returns
  true if widget contains no text

## ◆ isTextValid()

bool FloatingTextWidget::isTextValid | ( | const QString & | text | ) |
| static

For a text to be valid it must be non-empty, i.e. have a length larger than zero, and have at least one non whitespace character.

Parameters

  text | The string to analyze.

Returns
  True if the given text is valid.

## ◆ link()

LinkWidget * FloatingTextWidget::link | ( |  | ) | const

Returns the LinkWidget this floating text is related to.

Returns
  The LinkWidget this floating text is related to.

## ◆ loadFromXMI()

bool FloatingTextWidget::loadFromXMI | ( | QDomElement & | qElement | ) |
| virtual

Loads the "floatingtext" XMI element.

Reimplemented from UMLWidget.

## ◆ minimumSize()

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

Overrides method from UMLWidget.

Reimplemented from UMLWidget.

## ◆ moveWidgetBy()

void FloatingTextWidget::moveWidgetBy | ( | qreal | diffX,
|  | qreal | diffY )
| protectedvirtual

Overridden from UMLWidget. Moves the widget to a new position using the difference between the current position and the new position. If the floating text widget is part of a sequence message, and the message widget is selected, it does nothing: the message widget will update the text position when it's moved. In any other case, the floating text widget constrains its move using constrainPosition. When the position of the floating text is constrained, it's kept at that position until it can be moved to another valid position (m_unconstrainedPositionX/Y and m_movementDirectionX/Y are used for that). Moreover, if is part of a sequence message (and the message widget isn't selected), it updates the position of the message widget.

See also
  constrainPosition

Parameters

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

Reimplemented from UMLWidget.

## ◆ onWidget()

UMLWidget * FloatingTextWidget::onWidget | ( | const QPointF & | p | ) |
| virtual

Override method from UMLWidget in order to additionally check widget parentage.

Parameters

  p | Point to be checked.

Returns
  'this' if UMLWidget::onWidget(p) returns non 0; else NULL.

Reimplemented from WidgetBase.

## ◆ paint()

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

Overrides default method

Reimplemented from UMLWidget.

## ◆ postText()

QString FloatingTextWidget::postText | ( |  | ) | const

Use to get the post-text which is appended to the main body of text to be displayed.

Returns
  The post-text currently displayed by the widget.

## ◆ preText()

QString FloatingTextWidget::preText | ( |  | ) | const

Use to get the pre-text which is prepended to the main body of text to be displayed.

Returns
  The pre-text currently displayed by the widget.

## ◆ saveToXMI()
