Detailed Description

Widget for rendering the score.

This class represents the widget capable of rendering the score. It is usually used as a central widget in the main window, but might be used for example, in a list of possible harmonization or improvization solutions, score layout window and more as an independent widget or only as a drawable content on a button.

Score viewport consists of a virtual workspace full of drawable elements which represent the abstract music elements or contexts. Every drawable element has its absolute X, Y, Width and Height geometry properties. Score viewport also shows usually a small part of the whole workspace (depending on scroll bars values and a zoom level). When drawable elements are drawn, their CADrawable::draw() methods are called with the viewports X and Y coordinates, zoom level, pen color and other properties needed to correctly draw an element to the score viewport's canvas.

Note that this widget is only capable of correctly rendering the drawable elements. No Control part of the MVC model is implemented here. The viewport logic is implemented outside of this class (usually main window). Score viewport only provides various signals to communicate with outer world. However, this class provides various modes (eg. drawing the shadow notes when inserting music elements, coloring only one voice, hiding certain staffs, animating the scroll etc.) the controller might use.

This widget also provides horizontal and vertical scrollbars (see _hScrollBar and _vScrollBar).

Member Enumeration Documentation

enum CAScoreViewPort::CAScrollBarVisibility

Different behaviour of the scroll bars:

• ScrollBarAlwaysVisible - scrollbars are always visible, no matter if the whole scene can be rendered on canvas or not
• ScrollBarAlwaysHidden - scrollbars are always hidden, no matter if the whole scene can be rendered on canvas or not
• ScrollBarShowIfNeeded - scrollbars are visible, if they are needed (the current viewport area is too small to render the whole scene), otherwise hidden. This is default behaviour.

Here is the caller graph for this function:

void CAScoreViewPort::CAKeyPressEvent ( QKeyEvent *  e )

signal

This signal is emitted when keyPressEvent() is called. Parent class is usually connected to this event. It adds another two arguments to the wheelEvent() function - pointer to this score viewport. This is useful when a parent class wants to know which class the signal was emmitted by.

Parameters

e	Wheel event which gets processed.
