Detailed Description

Controller for FloatingTextWidget.

When moving a FloatingTextWidget, it is constrained using constrainTextPos method from the LinkWidget, if any. This applies both when moving as part of a selection and when constraining the move of the selection because it's the receiver of mouse move events. The only exception to this is that when moving the widget, if it's a sequence message and the message widget is selected, the floating text widget isn't moved itself, but automatically by the message widget. If the sequence message wasn't part of the selection, the floating text widget moves it. When moving the floating text as part of a selection, if the position of the floating text is constrained, it's kept at that position until it can be moved to another valid position. No resize is allowed for FloatingTextWidget.

Constructor & Destructor Documentation

FloatingTextWidgetController::FloatingTextWidgetController ( FloatingTextWidget * floatingTextWidget )

Constructor for FloatingTextWidgetController.

Parameters:

floatingTextWidget The floating text widget which uses the controller.

Definition at line 21 of file floatingtextwidgetcontroller.cpp.

FloatingTextWidgetController::~FloatingTextWidgetController ( )

Destructor for MessageWidgetController.

Definition at line 30 of file floatingtextwidgetcontroller.cpp.

Member Function Documentation

void FloatingTextWidgetController::saveWidgetValues ( QMouseEvent * me ) [protected, virtual]

Overridden from UMLWidgetController.
Saves the values of the widget needed for move/resize. Calls parent method and then saves the value of m_unconstrainedPositionX/Y and m_movementDirectionX/Y.

Parameters:

me The QMouseEvent to get the offset from.

Reimplemented from UMLWidgetController.
Definition at line 33 of file floatingtextwidgetcontroller.cpp.
References UMLWidget::getX(), UMLWidget::getY(), and UMLWidgetController::saveWidgetValues().

bool FloatingTextWidgetController::isInResizeArea ( QMouseEvent * me ) [protected, virtual]

Overridden from UMLWidgetController.
FloatingTextWidgets can't be resized, so this method always returns false. Cursor isn't changed.

Parameters:

me The QMouseEVent to check.

Returns:
true if the mouse is in resize area, false otherwise.

Reimplemented from UMLWidgetController.
Definition at line 42 of file floatingtextwidgetcontroller.cpp.

void FloatingTextWidgetController::moveWidgetBy ( int diffX,

int diffY

) [protected, virtual]

Overridden from UMLWidgetController.
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.

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 UMLWidgetController.
Definition at line 46 of file floatingtextwidgetcontroller.cpp.
References LinkWidget::calculateNameTextSegment(), UMLWidget::getHeight(), UMLWidget::getSelected(), MessageWidget::getSequenceMessageType(), MessageWidget::getWidget(), UMLWidget::getX(), UMLWidget::getY(), FloatingTextWidget::m_pLink, FloatingTextWidget::m_Role, UMLWidget::setX(), and UMLWidget::setY().

void FloatingTextWidgetController::constrainMovementForAllWidgets ( int & diffX,

int & diffY

) [protected, virtual]

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

Parameters:

diffX The difference between current X position and new X position.

diffY The difference between current Y position and new Y position.
