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 ( )

default

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

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::edit::GeometriesUpdateTool, 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.

bool te::qt::widgets::AbstractTool::keyPressEvent ( QKeyEvent *  e )

virtualinherited

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

Parameters

e	The key event.

Returns

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

Reimplemented in te::qt::widgets::Measure.

Definition at line 101 of file AbstractTool.cpp.

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.
