Detailed Description

Class is STRATEGY pattern for mode construction. Includes method for selecting objects on page and manipulating with him.

This implementation is for selecting only annotation on the page. If mouse cursor is over some annotation, then emits new selected annotation. If click on annotation emit required execute script commad.

Member Function Documentation

void gui::PageViewMode_Annotations::actualizeSelection ( ) [virtual, slot]

Actualize selected operators on the page.

Method is reimplemented from parent and nothing operators are be set.

Reimplemented from gui::PageViewMode.

Add operators selected on the page.

Parameters:

sOps

Vector of operators.

Method is reimplemented from parent and nothing operators are be set.

Reimplemented from gui::PageViewMode.

void gui::PageViewMode_Annotations::addWorkOperators ( const std::vector< boost::shared_ptr< PdfOperator > > & wOps ) [virtual, slot]

Add operators for selection on the page.

Parameters:

wOps

Vector of operators.

Method is reimplemented from parent and nothing operators are be set.

Reimplemented from gui::PageViewMode.

void gui::PageViewMode_Annotations::clearSelectedOperators ( ) [virtual, slot]

Clear all operators and annotations which are selected on the page.

Reimplemented from gui::PageViewMode.

void gui::PageViewMode_Annotations::clearWorkOperators ( ) [virtual, slot]

Clear all operators and annotations which can be possible select on the page.

Reimplemented from gui::PageViewMode.

void gui::PageViewMode_Annotations::extraInitialize	(	const boost::shared_ptr< CPage > &	page,
		const DisplayParams &	displayParams
	)			`[virtual, slot]`

Extra initialization mode.

Parameters:

	page	Page which are viewed.
	displayParams	Display parameters viewed page.

This method is good called after change viewed page, or change display parameters (zoom, rotation, ...) Initialize annotation for selecting on the page page.

Reimplemented from gui::PageViewMode.

PageViewMode_Annotations::annot_rect gui::PageViewMode_Annotations::getAnnotationOnPosition ( const QPoint & p ) [protected]

Get struct for annotation and its activation rectangle for annotation under point on the page

Parameters:

p

Position on the page.

Returns:: Return initialized struct for annotation and its activation region. If nothing annotation is under position p, struct is initialized to null shared pointer to annotation.

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

Method is call if mouse is moving (see Qt::QWidget::mouseMoveEvent)

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.

Is switch which call other method. Is settings pomCur and mouse cursor for widget w.

void gui::PageViewMode_Annotations::movedSelectedObjects ( QPoint relativeMove ) [virtual, slot]

Method is calling if is need move selected region (operation 'move' is finished).

Parameters:

relativeMove

relativ move x and y position of selected region.

This method call script.

This implementation call script function 'scriptFncAtMouseRelease' if relativeMove is [0,0].

void gui::PageViewMode_Annotations::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.

void gui::PageViewMode_Annotations::resizedSelectedObjects	(	int	dleft,
		int	dtop,
		int	dright,
		int	dbottom
	)			`[virtual, slot]`

Method is calling if is need resize selected region (operation 'resize' is finished).

Parameters:

	dleft	delta position of bounding-rectangle's left edge of selected operators.
	dtop	delta position of bounding-rectangle's top edge of selected operators.
	dright	delta position of bounding-rectangle's right edge of selected operators.
	dbottom	delta position of bounding-rectangle's bottom edge of selected operators.
