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.

bool te::edit::CreatePolygonTool::mouseDoubleClickEvent ( QMouseEvent * e )

virtual

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

Definition at line 127 of file CreatePolygonTool.cpp.

bool te::edit::CreatePolygonTool::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::AbstractTool.

bool te::edit::CreatePolygonTool::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.
