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.

Constructor & Destructor Documentation

ToolBarStateArrow()

explicit

Creates a new ToolBarStateArrow.

Parameters

umlScene

The UMLScene to use.

Here is the call graph for this function:

~ToolBarStateArrow()

ToolBarStateArrow::~ToolBarStateArrow ( )

virtual

Destroys this ToolBarStateArrow.

Member Function Documentation

changeTool()

void ToolBarStateArrow::changeTool ( )

protectedvirtual

Overridden from base class to do nothing, as arrow is the default tool.

Reimplemented from ToolBarState.

cleanup()

void ToolBarStateArrow::cleanup

(

)

Clean up anything before deletion.

init()

void ToolBarStateArrow::init ( )

virtual

Goes back to the initial state.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseDoubleClickAssociation()

void ToolBarStateArrow::mouseDoubleClickAssociation ( )

protectedvirtual

Called when the double click event happened on an association. Delivers the event to the association.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseDoubleClickWidget()

void ToolBarStateArrow::mouseDoubleClickWidget ( )

protectedvirtual

Called when the double click event happened on a widget. Delivers the event to the widget.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseMoveAssociation()

void ToolBarStateArrow::mouseMoveAssociation ( )

protectedvirtual

Called when the move event happened when an association is currently available. Delivers the event to the association.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseMoveEmpty()

void ToolBarStateArrow::mouseMoveEmpty ( )

protectedvirtual

Called when the move event happened when no association nor widget are currently available. Updates the selection rectangle to the new position and selectes all the widgets in the rectangle.

Todo:

Fix selection

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseMoveWidget()

void ToolBarStateArrow::mouseMoveWidget ( )

protectedvirtual

Called when the move event happened when a widget is currently available. Delivers the event to the widget.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mousePressAssociation()

void ToolBarStateArrow::mousePressAssociation ( )

protectedvirtual

Called when the press event happened on an association. Delivers the event to the association.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mousePressEmpty()

void ToolBarStateArrow::mousePressEmpty ( )

protectedvirtual

Called when the press event happened on an empty space. Calls base method and, if left button was pressed, prepares the selection rectangle.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mousePressWidget()

void ToolBarStateArrow::mousePressWidget ( )

protectedvirtual

Called when the press event happened on a widget. Delivers the event to the widget.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseReleaseAssociation()

void ToolBarStateArrow::mouseReleaseAssociation ( )

protectedvirtual

Called when the release event happened on an association. Delivers the event to the association.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseReleaseEmpty()

void ToolBarStateArrow::mouseReleaseEmpty ( )

protectedvirtual

Called when the release event happened on an empty space. If selection rectangle is active, it is cleared. Else, if the right button was released, it shows the pop up menu for the diagram.

Reimplemented from ToolBarState.

Here is the call graph for this function:

mouseReleaseWidget()

void ToolBarStateArrow::mouseReleaseWidget ( )

protectedvirtual

Called when the release event happened on a widget. Delivers the event to the widget.

Reimplemented from ToolBarState.

Here is the call graph for this function:

setCurrentWidget()

void ToolBarStateArrow::setCurrentWidget ( UMLWidget *  widget )

protectedvirtual

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 canceling the movement in the big widget.

Reimplemented from ToolBarState.

Here is the call graph for this function:

Member Data Documentation

m_selectionRect

QList<QGraphicsLineItem*> ToolBarStateArrow::m_selectionRect

protected

The selection rectangle that contains the four lines of its borders.

m_startPosition

QPointF ToolBarStateArrow::m_startPosition

protected

The start position of the selection rectangle.
