Constructor & Destructor Documentation

te::qt::widgets::ExtentAcquire::ExtentAcquire	(	MapDisplay *	display,
		const QCursor &	cursor,
		QObject *	parent = `0`
	)

It constructs a extent acquire tool associated with the given map display and with the specified cursor.

Parameters

display	The map display associated with the tool.
cursor	The tool cursor.
parent	The 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.

te::qt::widgets::ExtentAcquire::~ExtentAcquire ( )

Destructor.

te::qt::widgets::ExtentAcquire::ExtentAcquire ( const ExtentAcquire & rhs )

private

Copy constructor not allowed.

Parameters

rhs	The right-hand-side copy that would be used to copy from.

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

watched	The watched object.
event	The 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.

void te::qt::widgets::ExtentAcquire::extentAcquired ( te::gm::Envelope env )

signal

This signal is emitted when a envelope was acquired.

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

e	The 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::SplitPolygonTool, te::edit::CreatePolygonTool, te::edit::CreateLineTool, te::edit::CreatePointTool, te::qt::widgets::PolygonAcquire, te::edit::AggregateAreaTool, te::edit::SubtractAreaTool, and te::mnt::ProfileTools.

bool te::qt::widgets::ExtentAcquire::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

e	The 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::RubberBand.

bool te::qt::widgets::ExtentAcquire::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

e	The 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::RubberBand.

bool te::qt::widgets::ExtentAcquire::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

e	The 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::RubberBand.

ExtentAcquire& te::qt::widgets::ExtentAcquire::operator= ( const ExtentAcquire & rhs )

private

Assignment operator not allowed.

Parameters

rhs	The right-hand-side copy that would be used to copy from.

Returns: A reference to this object.

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

virtualinherited

It sets the tool cursor.

Parameters

cursor The cursor that will be used during the tool operation.
