Detailed Description

Song editor.

The main widget of SongEditorPanel, responsible for altering the sequence of patterns.

It supports mouse and keyboard based activation of patterns in timeslots, as well as visual editing of multiple pattern+timeslot cells using a 2-dimensional visual representation, with copy, paste, move, delete, duplicate etc.

◆ yScrollTarget()

int yScrollTarget	(	QScrollArea *	pScrollArea,
		int *	pnPatternInView )

Calculate a target Y scroll value for tracking a playing song.

Songs with many patterns may not fit in the current viewport of the Song Editor. Depending on how the song is structured, as the viewport scrolls to show different times, the playing patterns may end up being off-screen. It would be ideal to be able to follow the progression of the song in a meaningful and useful way, but since multiple patterns may be active at any one time, it's non-trivial to define a useful behaviour that captures more than the simple case of a song with one pattern active at a time.

As an attempt to define a useful behaviour which captures what the user might expect to happen, we define the behaviour as follows:

If there are no currently playing patterns which are entirely visible:
- Find the position with the smallest amount of scrolling from the current location which:
  - Fits the maximum number of currently playing patterns in view at the same time.

This covers the trivial cases where only a single pattern is playing, and gives some intuitive behaviour for songs containing multiple playing patterns where the general progression is diagonal but with constant (or near-constant) background elements, and the "minimum scrolling" allows the user to hint if we stray off the path.
