void gui::PageViewMode_TextSelection::mouseMoveWithPressedLeftButton	(	QMouseEvent *	e,
		QPainter *	p,
		QWidget *	w
	)			`[virtual, slot]`

Method is calling if is press left mouse button and is moving with mouse.

Parameters:

	e	Pointer to mouse event (see Qt::QMouseEvent).
	p	Pointer to initialized painter for draw changes (see Qt::QPainter). Method emit at end 'needRepaint' if p is NULL.
	w	Pointer to widget (see Qt::QWidget). E.g. for change mouse cursor above operators.

See also:: updateSelection; PageViewMode::mousePressEvent

If is selecting action (mousePressLeftButton find and select one text operator), method find the nearest text operator to mouse cursor and select all text operator from first selected text operator to it respecting word and line order.

Reimplemented from gui::PageViewMode.

void gui::PageViewMode_TextSelection::mousePressLeftButton	(	QMouseEvent *	e,
		QPainter *	p,
		QWidget *	w
	)			`[virtual, slot]`

Method is calling if is release left mouse button.

Parameters:

	e	Pointer to mouse event (see Qt::QMouseEvent).
	p	Pointer to initialized painter for draw changes (see Qt::QPainter). Method emit at end 'needRepaint' if p is NULL.
	w	Pointer to widget (see Qt::QWidget). E.g. for change mouse cursor above operators.

See also:: mousePressLeftButton; PageViewMode::mousePressEvent

Method find the nearest text operator below mouse cursor. If cursor is not over text operator, nothing do.

void gui::PageViewMode_TextSelection::mouseReleaseLeftButton	(	QMouseEvent *	e,
		QPainter *	p,
		QWidget *	w
	)			`[virtual, slot]`

Method is calling if is release left mouse button.

Parameters:

	e	Pointer to mouse event (see Qt::QMouseEvent).
	p	Pointer to initialized painter for draw changes (see Qt::QPainter). Method emit at end 'needRepaint' if p is NULL.
	w	Pointer to widget (see Qt::QWidget). E.g. for change mouse cursor above operators.

void gui::PageViewMode_TextSelection::repaint	(	QPainter &	p,
		QWidget *	w
	)			`[virtual, slot]`

Repaint method for draw actual state of mode (selected region, moving and resizing in action, ...).

Parameters:

	p	Pointer to initialized painter for draw changes (see Qt::QPainter). Method emit at end 'needRepaint' if p is NULL.
	w	Pointer to widget (see Qt::QWidget). E.g. for change mouse cursor above operators.

It is only drawing method use, if viewing parent need clear repaint.

		std::vector< boost::shared_ptr< PdfOperator > > *	selOps = `NULL`
	)			`[protected]`

Method update selected operators and add new or remove operators from vector of selected operators.

Parameters:

	first	First selected operator (pointer to sorted structure by line and word on line)
	last	Last selected operator (pointer to sorted structure by line and word on line)
	selOpsRegion	Bounding region of all selected operators.
	selOps	Vector of selected operators.

Method find the nearest text operator to mouse cursor and select all text operator from first selected text operator to it respecting word and line order. New selected operators add to selOps. Removed selected operators remove from that. Actualize selOpsRegion by selOps.
