Detailed Description

Association tool to create associations between widgets.

With association tool, two widgets are selected clicking with left button on them and an association of the needed type (depending on the association button selected) is created between the widgets. When the first widget is selected, a temporal visual association that follows the cursor movement is created until the second widget is selected or the association cancelled.

Also, association tool can create association class: a classifier widget which is linked to an association. To do this, the classifier must be selected first and then the association must be selected. The association can't be selected first.

An association can be cancelled using right button, which also returns to default tool, or with middle button, which only cancels the association without changing the tool being used.

Member Function Documentation

void ToolBarStateAssociation::init ( ) [virtual]

Goes back to the initial state.

Reimplemented from ToolBarState.
Definition at line 45 of file toolbarstateassociation.cpp.
References ToolBarState::init().

void ToolBarStateAssociation::cleanBeforeChange ( ) [virtual]

Called when the current tool is changed to use another tool.
Executes base method and cleans the association.
Reimplemented from ToolBarState.
Definition at line 51 of file toolbarstateassociation.cpp.
References ToolBarState::cleanBeforeChange().

void ToolBarStateAssociation::mouseMove ( QMouseEvent * ome ) [virtual]

Called when a mouse event happened.
It executes the base method and then updates the position of the association line, if any.
Reimplemented from ToolBarState.
Definition at line 57 of file toolbarstateassociation.cpp.
References ToolBarState::mouseMove().

void ToolBarStateAssociation::slotWidgetRemoved ( UMLWidget * widget ) [virtual, slot]

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 widget, the association is cleaned.
Reimplemented from ToolBarState.
Definition at line 66 of file toolbarstateassociation.cpp.
References ToolBarState::slotWidgetRemoved().

void ToolBarStateAssociation::mouseReleaseAssociation ( ) [protected, virtual]

Called when the release event happened on an association.
If the button pressed isn't left button, the association being created is cleaned. If it is left button, and the first widget is set and is a classifier widget, it creates an association class. Otherwise, the association being created is cleaned.
Reimplemented from ToolBarState.
Definition at line 74 of file toolbarstateassociation.cpp.
References AssociationWidget::createAssocClassLine(), WidgetBase::getBaseType(), and ToolBarState::getCurrentAssociation().

void ToolBarStateAssociation::mouseReleaseWidget ( ) [protected, virtual]

Called when the release event happened on a widget.
If the button pressed isn't left button, the association is cleaned. If it is left button, sets the first widget or the second, depending on whether the first widget is already set or not.
Reimplemented from ToolBarState.
Definition at line 87 of file toolbarstateassociation.cpp.

void ToolBarStateAssociation::mouseReleaseEmpty ( ) [protected, virtual]

Called when the release event happened on an empty space.
Cleans the association.
Reimplemented from ToolBarState.
Definition at line 108 of file toolbarstateassociation.cpp.
