Detailed Description

Arrow tool for select, move and resize widgets and associations.

Arrow tool delegates the event handling in the widgets and associations. When no widget nor association is being used,the arrow tool acts as a selecting tool that selects all the elements in the rectangle created when dragging the mouse.

This is the default tool.

void ToolBarStateArrow::setCurrentWidget ( UMLWidget * currentWidget ) [protected, virtual]

Sets the widget currently in use.
It ensures that the widget is only set if there is no other widget set already. It avoids things like moving a big widget over a little one, clicking right button to cancel the movement and the little widget getting the event, thus not cancelling the movement in the big widget.
