Detailed Description

Controller for ObjectWidget.

When moving an ObjectWidget, it is only moved along X axis. Y axis movement is always ignored. So, if the ObjectWidget is being moved as part of a selection and that selection is moved in X and/or Y axis, the ObjectWidget will only move in X axis. Also, when constraining the move of the selection because the receiver of mouse move events is an ObjectWidget, all the widgets are moved only in X axis.

Only horizontal resize is allowed for ObjectWidget. Cursor is set to reflect this.

Constructor & Destructor Documentation

ObjectWidgetController::ObjectWidgetController ( ObjectWidget * objectWidget )

Constructor for ObjectWidgetController.

Parameters:

objectWidget The object widget which uses the controller.

Definition at line 23 of file objectwidgetcontroller.cpp.

ObjectWidgetController::~ObjectWidgetController ( ) [virtual]

Destructor for ObjectWidgetController.

Definition at line 27 of file objectwidgetcontroller.cpp.

Member Function Documentation

QCursor ObjectWidgetController::getResizeCursor ( ) [protected, virtual]

Overriden from UMLWidgetController.
Returns the cursor to be shown when resizing the widget. The cursor shown is KCursor::sizeHorCursor().

Returns:
The cursor to be shown when resizing the widget.

Reimplemented from UMLWidgetController.
Definition at line 30 of file objectwidgetcontroller.cpp.

void ObjectWidgetController::resizeWidget ( int newW,

int newH

) [protected, virtual]

Overriden from UMLWidgetController.
Resizes the width of the object widget. Object widgets can only be resized horizontally, so height isn't modified.

Parameters:

newW The new width for the widget.

newH The new height for the widget (isn't used).

Reimplemented from UMLWidgetController.
Definition at line 34 of file objectwidgetcontroller.cpp.
References UMLWidget::getHeight(), and UMLWidget::setSize().

void ObjectWidgetController::moveWidgetBy ( int diffX,

int diffY

) [protected, virtual]

Overriden from UMLWidgetController.
Moves the widget to a new position using the difference between the current position and the new position. Y position is ignored, and widget is only moved along X axis.

Parameters:

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

diffY The difference between current Y position and new Y position (isn't used).

Reimplemented from UMLWidgetController.
Definition at line 38 of file objectwidgetcontroller.cpp.
References UMLWidget::getX(), and UMLWidget::setX().

void ObjectWidgetController::constrainMovementForAllWidgets ( int & diffX,

int & diffY

) [protected, virtual]

Overriden from UMLWidgetController.
Modifies the value of the diffX and diffY variables used to move the widgets. All the widgets are constrained to be moved only in X axis (diffY is set to 0).

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 42 of file objectwidgetcontroller.cpp.
