Constructor & Destructor Documentation

te::qt::widgets::RubberBand::RubberBand ( MapDisplay display,
QObject *  parent = 0 
)

It constructs a rubber band associated with the given map display and with the specified cursor.

Parameters
displayThe map display associated with the tool.
parentThe tool's parent.
Note
The tool will NOT take the ownership of the given pointers.
If the given cursor is different of Qt::BlankCursor, it will be setted on map display.
virtual te::qt::widgets::RubberBand::~RubberBand ( )
virtual

Destructor.

Member Function Documentation

virtual bool te::qt::widgets::AbstractTool::eventFilter ( QObject *  watched,
QEvent *  e 
)
virtualinherited

Filters events if this object has been installed as an event filter for the watched object.

Parameters
watchedThe watched object.
eventThe last event sent to watched object.
Note
In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
Here, the default implementation looks for QMouseEvents and call the pure virutal methods defined on AbstractTool class, e.g. mousePressEvent().

Reimplemented in te::qt::widgets::ZoomKeyboard, and te::qt::widgets::ZoomWheel.

virtual bool te::qt::widgets::AbstractTool::mouseDoubleClickEvent ( QMouseEvent *  e)
virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse double click events for the watched object.

Parameters
eThe mouse event.
Returns
If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
Note
The AbstractTool will also receive mouse press and mouse release events in addition to the double click event. It is up to the developer to ensure that the application interprets these events correctly.

Reimplemented in te::edit::VertexTool, te::qt::widgets::Measure, te::edit::CreateLineTool, te::edit::CreatePolygonTool, te::qt::widgets::PolygonAcquire, te::edit::AggregateAreaTool, and te::edit::SubtractAreaTool.

virtual bool te::qt::widgets::RubberBand::mouseMoveEvent ( QMouseEvent *  e)
virtual

This event handler can be reimplemented in a concrete tool class to receive mouse move events for the watched object.

Parameters
eThe mouse event.
Returns
If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented from te::qt::widgets::AbstractTool.

Reimplemented in te::qt::widgets::Selection, te::qt::widgets::ExtentAcquire, and te::qt::widgets::ZoomArea.

virtual bool te::qt::widgets::RubberBand::mousePressEvent ( QMouseEvent *  e)
virtual

This event handler can be reimplemented in a concrete tool class to receive mouse press events for the watched object.

Parameters
eThe mouse event.
Returns
If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented from te::qt::widgets::AbstractTool.

Reimplemented in te::qt::widgets::Selection, te::qt::widgets::ExtentAcquire, and te::qt::widgets::ZoomArea.

virtual bool te::qt::widgets::RubberBand::mouseReleaseEvent ( QMouseEvent *  e)
virtual

This event handler can be reimplemented in a concrete tool class to receive mouse release events for the watched object.

Parameters
eThe mouse event.
Returns
If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented from te::qt::widgets::AbstractTool.

Reimplemented in te::qt::widgets::Selection, te::qt::widgets::ExtentAcquire, and te::qt::widgets::ZoomArea.

virtual void te::qt::widgets::AbstractTool::setCursor ( const QCursor &  cursor)
virtualinherited

It sets the tool cursor.

Parameters
cursorThe cursor that will be used during the tool operation.
